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.

Incorporation of MPCM on cotton fabric for potential application in hospital bed sheet

Over the last few decades, phase change materials (PCM) have attracted a great deal of interest in medical textiles due to its superior thermoregulation system, simple application, and so on. Patients, however, confined to bed in a medical facility face the serious risk of developing bed sores, which is not mitigated by the use of a standard bed sheet. Numerous articles and patents have been studied related to development of thermal bed sheets using PCM applied by various techniques; however, no such initiates was found to prepare and characterize of hospital bed sheets using microencapsulated phase change material (MPCM) through screen printing method. Thus, this study aims to develop a hospital bed sheet constructed from cotton fabric incorporated with MPCM. To accomplish this, MPCM was mixed into the printing paste that had been applied on the fabric by screen printing method, and then dried at room temperature. Thermal behavior, thermal transition, and thermal conductivity of the developed samples had been investigated. Moisture management properties, mechanical properties, and bonding behavior of the samples were also examined. Scanning electron microscope (SEM) was used to analyze the sample's morphology, and a differential scanning calorimeter (DSC) was used to determine how polymeric materials behaved when heated. Thermogravimetric analysis (TGA) demonstrated that the MPCM incorporated sample lost weight slowly, while the DSC test confirmed that melting began at 20 °C and ended at 30 °C. Furthermore, fabricated sample had higher heat conductivity (0.1760822 w.m−1 k−1). Overall, the results revealed a great potential for using the developed samples as hospital bed sheets to prevent patients from developing bed sores.

Interrelationships between cotton fiber quality traits and fluid handling and moisture management properties of nonwoven textiles

Cotton fibers represent a sustainable and environmentally responsible raw material for the production of nonwoven textiles which are currently dominated by synthetic fibers derived from petrochemicals. Natural variation in quality parameters such as fineness, length, and strength present a challenge for cotton fiber conversion to yarns and in weaving and knitting for conventional textiles. The grading process for cotton fibers addresses this issue by allowing converters to select fibers suitable for specific woven textile applications. However, there has been little attempt to correlate cotton fiber quality traits with nonwoven textiles performance. This study examined the relationship of cotton fiber quality and fluid handling and moisture management performance properties of nonwoven textiles for personal hygiene and disposable applications. This includes potential end-use in diapers and incontinence products as well as disposable textiles for use in clinical settings. Ten recombinant inbred lines of cotton with a broad distribution of fiber quality traits were selected from a multiparent advanced generation intercross population. Fibers were harvested, converted into nonwoven textiles, and subjected to a series of standardized testing protocols. The results indicated that inferior quality coarse cotton fibers subjected to discount market pricing can be selectively utilized for nonwoven applications that benefit from improved moisture management and fluid handling performance.

According to experimental data, the effect of filament composition on the thermal comfort properties of fabric was analyzed.FindingsThe increasing difference of hydrophilicity between inner and outer layers resulted in the enhancement of moisture management properties. Better thermal-physiology performance was exhibited by fabrics made up of finer and circular section fibers. Excellent thermal transfer, drying performance and one-way water transport capacity benefited the improvement of dynamic cooling effect of fabrics.Originality/valueThis work provides a useful and effective method for the development of bi-layer knitted fabric applied for sports and summer clothing.

Electrospun bio-nano hybrid scaffold from collagen,Nigella sativa, and chitosan for skin tissue engineering application

The new sophisticated tissue engineering focused on producing nanocomposite with different morphologies for rapid tissue regeneration. In this case, utilizing nanotechnology with the incorporation of bio-based materials have achieved the interest of researchers. This research aims at developing hybrid bio-nano scaffold with collagen (Col), Nigella sativa ( Ns), and chitosan (Cs) by a bi-layered green electrospinning on polyvinyl chloride (PVA) layer in a different ratio for tissue regeneration. Field emission electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FTIR), moisture management properties, tensile properties, antibacterial activity, and wound healing assessment of the fabricated hybrid bio-nano scaffolds were employed to investigate the different properties of hybrid bio-nano scaffolds. The results exhibit that the sample with Col (50%) and Ns (25%), Cs (25%) has good fiber formation with a mean diameter of 381 ± 22 nm. This bio-nano scaffold has a porosity of 78 ± 6.9% and a fast absorbing-slow drying nature for providing a moist environment. The antibacterial zones of inhibition (ZOI) against Staphylococcus aureus and Escherichia coli were 10 ± 1.3 and 8 ± 0.9 mm respectively, and appeared to be adequate to inhibit bacterial action. The wound healing assessment states that 84 ± 3.8% of wound closure occurs in just 10 days, which is quicker (1.5 times) than the duration of a commercial bandage. All of the findings suggest that the bio-nano scaffold could be useful for skin tissue engineering.

Design and characterization of reversible thermodynamic SMPU-based fabrics with improved comfort properties

In recent years, great efforts have been made to research and develop advanced thermodynamic textiles that can change their thermal behavior in response to external stimuli. More specifically, shape memory alloys and shape memory polymer coatings have used for thermal comfort applications. However, the use of shape memory polymers in the form of filament yarns integrated in the fabrics has not yet reported. These fabrics have some advantages related to versatility in shape design. The aim of this study was to develop woven SMPU-based fabrics with reversible thermodynamic properties induced by weft SMPU filament yarns interlaced into polyester (PES) fabrics. To this end, PES woven fabrics with different ratios of weft SMPU filament yarns (PES/SMPU 1:0; 3:1; 1:1; 1:3, and 0:1) were developed and their thermodynamic properties (thermal resistance, water vapor resistance, and permeability index), shape memory effect, and mechanical performance were evaluated and compared to the 100% PES reference fabric. All the SMPU-based fabrics developed were classified as extremely breathable (water vapor resistance <6 m2·Pa/W) and thermally comfortable (water vapor permeability index <0.3). The fabrics integrating the SMPU filament yarns reacted dynamically to the temperature stimuli over and below Tg, whereas the 100% PES fabric showed passive thermodynamic behavior. This dynamism led to an improvement in thermal protection against an increase in ambient temperature, reaching values of 13.18 mK·m2/W in thermal resistance (PES/SMPU 0:1), while also maintaining good moisture management properties, reaching values of 5.19 m2·Pa/W in water vapor resistance (PES/SMPU 0:1).

Effect of plasma treatment on polyester knitted fabrics: Part II — Moisture management properties

This study focuses on the moisture management properties of plasma-treated polyester knitted fabrics (spun, continuous filament, micro denier and hollow fibre). The effect of different loop lengths and the impact of oxygen plasma treatment on the moisture management properties of the fabric has also been studied. The moisture management properties are better for the plasma-treated fabric and also for the fabric having highest loop length. The moisture management properties of the fabric have been improved with the oxygen plasma treatment.

Moisture management properties and drying behaviour of knitted fabrics for inner layer applications

The present research work is focused on moisture management properties and drying behaviour of various knitted fabrics for inner layer application. Nineteen knitted samples have been prepared by changing the blend percentage of wool/acrylic, number of filaments in polypropylene yarn and structure of knitted fabric. Yarns of different blend ratio of wool/acrylic fibre are used to knit fabrics of different structure. Polypropylene yarns having different number of filaments are also used to knit samples of different structure. These fabrics are tested for moisture management properties and drying behaviour. Wetting time, absorption rate, spreading speed, wetting radius, accumulative one-way transport index (AOWTI), overall moisture management capacity (OMMC), drying time and drying rate of the fabrics have been studied. It is observed that the overall performance of polypropylene knitted fabric and cotton knitted fabric are better as compared to the wool/acrylic having same structural parameters. The OMMC index of polypropylene plain knit, pile knit and cotton knit fabric is found as 0.70, 0.60 and 0.75 respectively. The polypropylene and cotton knitted fabrics shows better results than others in terms of the parameters, like maximum wetting radius, AOWTI, etc. Polypropylene knitted pile structure fabric shows minimum drying time (0.228 h) and zero residual moisture after wash at 90 min under standard conditions. So, it is found that the higher wool content in fabrics gives better moisture management and drying behaviour. Polypropylene fabrics having high number of filaments in the constituent yarn show better moisture management and drying behaviour than the wool/acrylic fabrics. Moisture management and drying behaviour of pile fabrics are better than the plain and rib fabrics.
