Effect of Weave and Weft Type on Mechanical and Comfort Properties of Hemp-Linen Fabrics.

In this study the influence of fabric weave (plain, twill, and panama) and weft type (flax and hemp yarns) on selected mechanical and comfort properties of six fabrics was analyzed. The results showed that tear and abrasion properties were most affected by the weave. The tensile properties of the linen fabrics were not significantly different when weft hemp yarns were used instead of flax. Fabrics with the same weave seemed to be equally resilient to abrasion regardless of the type of weft. By contrast, the hemp weft yarns favorized the physical and comfort properties of the investigated fabrics. For the same weave, the hemp-linen fabrics were slightly lighter and exhibited lower bulk density, significantly larger air permeability, and improved moisture management properties. Although the results of maximum thermal flux (Qmax) suggested a cooler sensation of the linen fabrics with panama and twill, the hemp-linen fabric with a plain weave seemed to be the optimal choice when a cool sensation was desired. Higher thermal conductivity values also suggested slightly better heat transfer properties of the hemp-linen fabrics, and these were significantly influenced by the weave type. The results clearly indicated the advantages of using hemp for improving physical and specific comfort properties of linen fabrics.

Advancements in Cotton Textile Design: Addressing Temperature and Moisture Challenges

The primary objective of this study is to alleviate discomfort arising from fluctuations in heat and humidity due to environmental and personal factors, aiming to develop functional textiles capable of effectively responding to these changes. To achieve this, systematic pattern designs were implemented on 100% cotton woven fabrics, incorporating hydrophobic characteristics through the application of a water-repellent agent to specific areas. The resulting compatibility of these hydrophobic features with hydrophilic elements endowed the fabrics with moisture management properties. Furthermore, the introduction of a phase-changing material agent to these fabrics imparted heat management capabilities. The rotation printing technique was employed to seamlessly transfer these agents onto the fabric. In assessing the durability of woven fabrics featuring distinct functionalities, a comprehensive examination was conducted, subjecting them to 30 repeated wash cycles within a single process step. The morphological structures of the fabrics produced were meticulously analyzed using SEM (scanning electron microscopy), SEM–EDX (energy-dispersive X-ray analysis) while their chemical compositions were scrutinized through FTIR–ATR (Fourier transform infrared spectroscopy–attenuated total reflectance). Additionally, a battery of tests, including physical, chemical, liquid absorption, liquid transfer assessments, and DSC (differential scanning calorimetry) analyses, were conducted in accordance with relevant standards. The outcomes of this study demonstrated that the fabrics not only met the criteria of the TS 866 standard, particularly with regard to a rapid response time of less than 10 s, but also exhibited resilience to repeated washings, affirming the enduring efficacy of the incorporated functionalities. According to tearing strength results, slight increase was also observed in treated cotton fabrics.

A Prospective Comparison of Materials and Structures for Sports Graduated Compression Socks

Abstract Compression socks have an effective role in the performance activity of athletes. This study aims to quantify the effect of fiber materials and structure on physical, mechanical, thermo-physiological, sensorial, and ergonomic comfort on sports graduated compression socks (SGCS). Two natural fibers, cotton and viscose, and two synthetic fibers, Coolmax and acrylic, were used to develop three different types of SGCS. Data have been analyzed by full factorial design of experiment. The finding exhibited that Coolmax-based socks have better moisture management and dimensional properties as compared with other materials. Acrylic-based SGCS are better to use in winter because of their higher thermal resistance, besides moderate moisture management. Moreover, it is verified that higher bursting strength is achieved by using higher-strength fibers. Additionally, it was observed that the effect of structure and material on desired properties without compromising compression/interface pressure is statistically significant. The overall properties of the developed stockings are better in terms of properties than market stockings. For all the socks, compression pressure between 15 and 20 mmHg, as per requirements of sports socks, was maintained. The effect of materials and structure on the aforementioned responses were examined using analysis of variance statistical analysis. The functional properties are greatly influenced by the material and structure. In this study, the comfort properties are considered to play a major functional role regarding usage by the end user. Its use not only maintained blood circulation by applying external pressure but also defended against unexpected harm or damage of vessels because of high pooling of blood during sports, running, or performance. This study will help to select suitable structure and materials for comfortable SGCS and is expected to fulfill the potential requirements of the athletes.

Evaluation of drying performance of sports bras

Introduction
 Fabrics used for manufacturing sports bras have to be lightweight, breathable, have fast drying behaviour, and moisture management properties (Uttam, 2013). Therefore, thermo-physiological comfort is an important quality criterion for sports bras (Carneiro et al., 2017). In addition, sports bras have to provide support to stabilize breasts during various physical activities (Ancutiene et al., 2017). These requirements lead to challenges in finding the best sports bra fabric, as bra support (Norris et al., 2021) and thermo-physiological comfort require contrasting fabric properties (Carneiro et al., 2017).
 This work aims to compare drying characteristics of different sports bras types (compression, encapsulation and combination) and fabrics used. A newly developed methodology to investigate the drying behaviour of sports bras in the lab has been taken for their examination.
 Methods
 The measurement set-up was built up in a climatic chamber (at 23°C and 50% RH). It consists of the upper body part of a female manikin, the air channel with fans and a balance to measure the weight change of the sports bra over time (indicative of the amount of moisture evaporated). The Infrared (IR) camera was used to record local surface temperature. Based on these measurements, the local and general drying performance of the sports bras were assessed based on dry fabric weight, moisture uptake, moisture absorption, drying time and drying rate.
 Results
 The results show that type of sports bra and material composition can have influence on better drying performance studied. The range of drying time for the different sport bra types was observed between 13 and 66 min for compression bras, 25 and 42 min for encapsulation bras, and between 35 and 43 min for combination bras. The moisture uptake was detected in a range between 6% and 15% for compression bras, 13% and 15% only for encapsulation bras, while between 7% and 19% for combination bras.
 Discussion/Conclusion 
 We were able to show that there is a significant difference in drying performance between sports bras. In combination with additional data about sensorial comfort and breast support, these findings provide a scientific basis for developing sports bras meeting specific requirements for various sports.

Investigation of comfort characteristics of knitted fabric produced from neppy yarn

Fabric made from fancy yarn, especially neppy yarn has a great environmental impact because the fabric does not need any additional dyeing process. This study involved knitting neppy yarn of two distinct spinning processes, vortex and ring spinning, each having three different percentages of neps. The comfort properties of six different fabrics were evaluated by analyzing various parameters, including moisture management properties, water vapor transmission rate, air permeability, hand feel properties, and bursting strength. Microscopic views were also examined for analyzing the physical appearance of the fabric’s surface. The experimental results revealed that fabrics made from vortex-spun neppy yarn (VSNY) exhibit better moisture management, breathability, and hand feel properties than ring-spun neppy yarn (RSNY). Alternatively, bursting strength and water vapor evaporation rate showed a lower trend in fabrics made from vortex-spun neppy yarn. The research findings contribute valuable insights into the potential of vortex spinning techniques for sustainable and comfortable textile production.

Research on thermal comfort and moisture management properties of drapery fabrics produced with polyester yarns having different fibre cross-sectional shapes and TiO2 amount

This study aims to provide an investigation regarding the effect of fibre cross-sectional shape, incorporated TiO2 amount (%) during polyester yarn production, and the weft density parameters respectively, on thermal comfort, moisture management, water vapour permeability, and air permeability properties of polyester drapery fabrics. Completely randomized three-factor analysis of variance (ANOVA) was conducted at the significance level of 0.05. SNK tests were also performed to observe the means of each parameter. Some of the weft yarn production parameters and the weft density (picks/cm) factors were found as significant factors in some thermal comfort and moisture management, water vapour, and air permeability properties of drapery samples.

A New Device (3D-MMD) and Method for Measuring Moisture Management Properties of Textiles

ABSTRACT Today, expectations from textile products have increased and the comfort features of clothes have gained more importance, especially for leisure and sports clothes. Therefore, the liquid moisture transmission of clothes is quite important, which has a significant effect on the body's ability to cool itself and the user's feeling cold after sweating. A new test instrument “3D-MMD” (3 Dimension Moisture Mapping Device), that measures the liquid moisture transmission feature of the fabrics in multidirection is introduced in this paper. The developed system includes two thermal cameras that allow measurement below and above of the sample. When the test liquid is dropped on the sample, the heat transfer occurs and due to the heat transfer during the transmission of moisture, the surface temperature of wetted and non-wetted parts of the fabric changes. This change is detected in the form of infrared data with the help of thermal cameras and converted into an electronic image. The wet area can be easily created by processing the images of the color visuals coming instantly from the thermal camera. The patent for this new method has been registered by the Turkish Patent and Trademark Office (TR2020/21004). Meanwhile, the international patent application process continues (PCT/TR2021/051223).

Impact of vitamin E in improving comfort, moisture management and mechanical properties of flame-retardant treated cotton fabric

The aim of this study is to analyze the use of vitamin E to enhance fabric's hand feel, moisture management and fabric strength which are affected due to flame retardant finish. Flame retardant treated fabrics typically become stiff, but the addition of Vitamin E along with emulsifier and binding agent through a vertical padding mangle by two times dipping and nipping results a soft fabric without impairing the flammability properties as determined by 45-degree flammability test. The samples were characterized by FTIR spectra, SEM images, and water contact angle. A new characteristics band is appeared at 1455 cm−1 for skeletal vibration of phenyl ring system of alpha tocopherol for Vitamin E measured by Fourier transform infrared spectroscopy (FTIR) that proves the effective attachment of vitamin E with fabric. Hydrophilicity of vitamin E containing sample is discovered after showing 37.629° as a water contact angle at optical tensiometer (Attension theta lite). Additionally, fabric comfort properties, moisture management properties, and mechanical properties were measured by fabric touch tester (FTT), moisture management tester (MMT) machine and tensile strength tester respectively that demonstrate significant affirmative change in almost all indexes of FTT, 43.5 % increase of overall moisture management capacity by MMT and 23 % increase of tear strength by tensile strength tester due to use of vitamin E that effectively compensate lower strength, poor fabric comfort, and low moisture management capability of flame retardant treated fabric.

Evaluation of the performance properties of modacrylic-cotton blended underwear fabrics manufactured for firefighters

In this study, the mechanical, comfort and flame-retardant properties of different knitted fabric structures containing modacrylic fibers with different blend ratios were investigated. Single jersey, rib, pique, three-thread fleece and interlock fabrics were produced with modacrylic/cotton blended yarns and evaluated comparatively. In order to understand the effect of antistatic fiber content on the investigated properties, two fabrics with antistatic fiber were produced. Since modacrylic fibers have moderate abrasion resistance, pilling resistances of the fabrics are not excellent. Due to the knitted fabrics having a soft and flexible structure, their fabric stiffness and bursting strength are quite high. It has been determined that water vapor resistances of all fabrics are satisfactory and the moisture management properties of the S1 (60% modacrylic, 40% cotton) and R1 (60% modacrylic, 40% cotton) fabrics are excellent. All the fabrics passed the flame-retardancy tests and it is sufficient that the modacrylic ratio is between 50% and 60% according to the fabric structure. Results also showed that 2% antistatic fiber content had no effect on the mechanical, thermal comfort and flame-retardancy properties. Since the air permeability, water vapor resistance and moisture management properties of S1 and R1 specimens are good enough, it is recommended to use one of them according to different temperature conditions. Evaluation of modacrylic fiber blended fabrics in different knitting types in terms of mechanical strength, thermal comfort and flame resistance properties together constitutes the originality of the work. Thus, it was possible to evaluate the effect of different knitting types and contents on all tests.

Improvement of mahogany leaf extract dye fixation on cotton-modal blend

The manufacture of regenerated cellulose-based fibers for better mechanical and comfort qualities was stimulated by the rising demand for cotton and the low production rate needed to meet global demands. Modal-cotton blend provides better tensile and moisture management properties. The present work has been designed to sketch out the scope of increased dye fixation or dye uptake opportunity onto the blends. Cotton-modal blend was dyed with mahogany leaf extract dyes avoiding mordant. The higher wash fastness rating 4/5, 5 along with the FTIR characteristic bands around 1190-1210 cm−1 created attention for the confirmation of dye-fibre bonding. But as modal is a regenerated cellulosic fibre, there was a suspect of uneven fixation because of dual way dye penetration options inside the fibre: direct bonding with cotton cellulose and dye penetration into swollen modal fibre through segmental mobility theory. Fortunately the uniformity of shade was affirmed by the determination of evenness through random CMC DE and K/S values at distinguished parts of the same sample. Mordantless mahogany dye fixation on cotton-modal blend was found even at the elevated dyeing temperature of 130 °C. The detailed CIE Lab data explored the close symmetry and uniformity of the dyeing outcomes of the blend.

Evaluation of the Moisture Management, Air and Water Vapour Permeabilities of Knitted Fabrics for Garments

The market today offers a variety of fabrics that may be utilised to create any style of clothing. Fabrics are periodically altered as a result of technology’s continual growth, to the point that it became difficult for clothes makers to assess the fabric characteristics related to thermal comfort. This paper reports some investigations on the moisture management and permeability properties of several commercial knitted fabrics intended for garment application. The fabric’s ability to manage moisture as well as its air and water vapour permeability were assessed. A fabric rating index was used to combine the results from each test to determine the fabric’s thermal comfort characteristics. Among the five knitted fabrics, the fabric comprised of nylon & polyester with jersey structure gave the highest assessment rating which is 5. The study serves as a future reference for future textile and garment industry, that implement the laboratory method used in this paper i.e moisture management, water vapour and air permeability in choosing the better thermal comfort qualities for general wear.

The visual perception of wetness: The role of stain chroma, size, and hue

AbstractA range of sensory cues contribute to human wetness perception, yet we know little of how visual modalities are involved, specifically if in‐situ physical observations differ from ex‐situ online observations. We aimed to assess the effect of stain volume, chroma, size, and hue on the wetness perception of static images, with a comparison to previously collected in‐situ data. A total of 440 participants completed the online study, including 18 from an analogous in‐situ study. Stimuli varied in physical wetness (0, 2.16 × 10−4 or 3.45 × 10−4 mL mm−2), stain chroma (clear saline, light synthetic urine, dark synthetic urine) and stain size (1150 or 5000 mm2). Further stimuli of a fixed wetness (3.45 × 10−4 mL mm−2) varied in stain hue (red, orange, yellow, green, blue, violet) and stain size (1150 or 5000 mm2). Participants rated wetness perception using a visual analogue scale (very dry to very wet) and modified yes/no task (dry/wet, gloss/matte, dilute/concentrate). Participants successfully discriminated between all physical wetness levels. Wetness perception shared a positive relationship with stain chroma and size, and varied with hue such that higher wavelengths resulted in greater wetness perception. Finally, online and in‐situ wetness perception did not significantly differ.Practical ApplicationsThe findings fundamentally contribute to our scientific understanding of wetness perception, giving evidence toward different multisensory integration theories. Further applications lie in industry, such as improving the structure, function, and perception of absorbent hygiene products or informing the design of sportswear with moisture management properties. Additionally, findings may aid the improvement of digital software which uses visual wetness components, for example in augmented and virtual realities.

Study on Moisture Management Properties of Cotton/Polyester Knitted Fabrics

Abstract Comfortability of a fabric is achieved by improving the moisture management behavior of the knitwear. In our study, the moisture management behavior of polyester and cotton fibers blended in 100:0, 50:50, and 0:100 ratios in four different structures such as single jersey, cross tuck, cross miss, and twill at two different loop lengths, 0.29 and 0.32 cm, were studied. Objective fabric tests were conducted to analyze the thermal properties of various knitwear. The results clearly proved that the knit fabric made of 100 % polyester has better moisture management behavior and a considerable level of comfort. Therefore, polyester can be applied to active sportswear fabrics. The structure of the fabric and the length of the loops in the fabric further affect the moisture management behavior. The cross-stitch 100 % polyester knit fabric with a loop length of 0.32 has excellent moisture management behavior, which provides excellent moisture management property compared with all other samples.

Evaluation of fabric liquid and moisture management properties at simulated skin and sweat temperatures using an advanced novel sweating simulator

The moisture management performance of fabrics under profuse sweating (i.e. the ability to sweat absorb, spread, evaporate, drip, and dry) is crucial to the wearer’s comfort and performance, and should therefore be accurately and realistically tested for quality evaluation and product development. However, it is challenging to measure these properties simultaneously under realistic conditions using current evaluation techniques or testing standards. In this article an advanced version of the novel sweating simulator (NSS) is presented with which the skin temperature, sweat temperature, active body posture, and varying sweating rates can be simulated and multiple fabric moisture management properties including liquid sweat accumulation rate, multi-directional spreading rates, variations in downflow rates caused by increasing liquid accumulation, discharge rate, evaporation rate, drying rate, and drying time can be measured concurrently and in real-time during the simulated sweating and drying phases. The high accuracy and excellent reproducibility of NSS measurements were demonstrated through testing eight different kinds of commercial moisture management fabrics to show the potential applications of the NSS. It is believed that the novel sweating simulator, owing to its comprehensive testing capability, will play a key role in the development of next-generation moisture management fabrics for numerous apparel and technical applications.

Antibacterial and Comfort Properties of Untreated Bamboo Fabric Related to Cotton Fabrics Treated with Zinc Oxide

The current study aims to evaluate and categorize bamboo fabric's functional and comfort properties. The study includes the selection of 100% bamboo fabrics of 127 g/m2 and 112 g/m2 and cotton fabrics of 104 g/m2. The cotton fabric was chemically processed and then treated with ZnO (1%, 2%, and 3%) using a padding machine. The antibacterial action of bamboo and ZnO-coated cotton samples was assessed and analysed against E. coli and S. aureus. The moisture properties of the chosen samples were tested. Further, the chosen samples are tested for properties like bending, drapeability, specific handle force, and air permeability. It was found that bamboo samples exhibit extensive microbial activity, and the same was proven through the 3% ZnO treatment of cotton samples. Both cotton and bamboo samples demonstrated enhanced moisture management properties. The comfort properties of bamboo samples are observed to be exceptional compared to cotton samples, making them more suitable for functions in situ than cotton.

Evaluation of air permeability and moisture management properties of jacquards and basic knitted fabrics

The flow of moisture through textile surfaces is a complex phenomenon as many factors influenceits transmission. The objective of this research work is to determine the effect of yarn and binding on their ability to prevent or promote moisture transmission within knitted structures. For this, we have developed a series of structures from cotton yarn and five types of polyester with different counts. The study of moisture transmission for the samples we have developed requires various tests to make a comprehensive study including air permeability, porosity, absorption rate, drying time, Fabric-vertical wicking, and moisture absorption. The results found by the absorption rate test showed that the pique jacquard absorbs better than the double face-one facejacquard. Based on the results of moisture management, air permeability and porosity, an optimum knitted structure is developed that corresponds to the good moisture transmission and the air permeability.

The Influence of Different Structures of Single-Knit Fabric on the Comfort Properties of Clothes

The purpose of this research is to determine the characteristics of variations in knitted structures on the comfort properties of materials in the form of porosity and moisture management properties in single knits fabrics. This research was carried out by varying the mesh structure in the form of all knit, knit knit – knit tuck, and variations of knit tuck – tuck knit, which then looked for the porosity value of the material using the image processing method of tresholding color map images by looking at the size of the empty space between materials. To see the properties of moisture management in single knit fabrics can be seen by looking at the value of air permeability, and the moisture management tester. From the experimental results, it was found that the porosity test results for structure 1 obtained a porosity value of 22.04%, for structure 2 it was 29.2% and for structure 3 it was 30.2%. where the test results show that the mesh structure with knit-knit tuck is the best mesh structure with an air permeability value of 735 cm3/cm2/s, and an OMMC value of 0.7447.
