Textile Recycling: Efficient Polyester Recovery from Polycotton Blends Using the Heated High-Ethanol Alkaline Aqueous Process.

Textile production has doubled in the last 20 years, but only 1% is recycled into new fibers. It is the third largest contributor to water pollution and land use, accounting for 10% of global carbon emissions and 20% of clean water pollution. A key challenge in textile recycling is blended yarns, such as polycotton blends, which consist of polyester and cotton. Chemical recycling offers a solution, in particular, alkali treatment, which hydrolyzes polyester (PET) into its components while preserving cotton fibers. However, conventional methods require high temperatures, long durations, or catalysts. Our study presents, for the first time, the heated high-ethanol alkaline aqueous (HHeAA) process that efficiently hydrolyzes PET from polycotton at lower temperatures and without a catalyst. A near-complete PET hydrolysis was achieved in 20 min at 90 °C, while similar results were obtained at 70 °C and 80 °C with longer reaction times. The process was successfully scaled at 90 °C for 20 min, and complete PET hydrolysis was achieved, with a significantly reduced liquid-to-solid ratio, from 40 to 7 (L per kg), signifying its potential to be implemented in an industrial context. Additionally, the cotton maintained most of its properties after the treatment. This method provides a more sustainable and efficient approach to polycotton recycling.

An eco-friendly droplet-wet spinning technology for producing high-quality hemp/cotton blend yarn

In recent years, hemp textiles have gained attention as a sustainable alternative to cotton. However, the uneven fineness and length of hemp fibers, along with their stiffness, adversely affect spinnability and exacerbate yarn evenness and hairiness, particularly due to short fibers. This study introduces a modified sustainable droplet-wet spinning technology aimed at enhancing hemp yarn quality, with a primary focus on reducing yarn hairiness. Implemented on a ring spinning machine, the technology utilizes a syringe connected to an adjustable-speed pump, delivering water onto the front top roller. This innovative approach enhances hemp yarn in two ways: firstly, the cohesive force of water promotes the consolidation of short fibers on both sides of the fiber bundle towards the center, thereby condensing the spinning triangle. Consequently, the fibers on both sides of the fiber bundle are more readily drawn into the spinning triangle and twisted to form yarn; secondly, wet hemp fibers possess a lower modulus, rendering them softer and more deformable, facilitating their embedding into the yarn, thereby enhancing yarn tenacity and reducing yarn hairiness. The study systematically investigates the relationship between droplet-wet spinning parameters (water droplet rate, hemp fiber content of the roving, and yarn twist multiplier) and hemp yarn quality. Experimental results reveals that optimal droplet-wet spinning lead to a 22% increase in yarn tenacity and about 50% reduction in hairiness. A higher hemp fiber content in the roving contributes to better performance of droplet-wet spinning technology in enhancing yarn quality. Moreover, droplet-wet spinning enables the production of high-quality hemp yarn at lower twist multipliers, thereby reducing electricity consumption during yarn production. Subsequently, the performance of knitted fabrics made from conventional ring-spun yarn and droplet-wet spun yarn was compared and analyzed. The results indicate that fabric made from droplet-wet spun yarn exhibits an approximately 8% increase in bursting strength and a one-level improvement in pilling resistance. This research highlights the potential of droplet-wet spinning technology to enhance hemp yarn quality and promote sustainable textile production.

Study on the relationship between blending uniformity and yarn performance of blended yarn

The performance of blended yarns is affected by the distribution of component fibers within blended yarn and the blending uniformity. However, there is a lack of comprehensive and quantitative investigations on the relationship between them. In this paper, various specifications for two-component blended yarns were prepared, and the main factors affecting blending uniformity were analyzed. Then the yarn blending irregularity and yarn performance, including tenacity, tenacity coefficient of variation, extension and yarn unevenness were tested. Finally, Pearson correlation analysis and linear regression were performed between blending irregularity and each yarn performance to characterize the influence of blending uniformity on yarn performance quantitatively. The results show that the blending irregularity is effectively improved by uniform feeding of slivers, and increasing the passage of sliver blending. The blending irregularity has no significant influence on the relationship between twist factor and yarn performance. The blending irregularity has the most positive and highest effect on tenacity coefficient of variation, followed by tenacity and unevenness in third place, and the Pearson correlation coefficient ( P) were all above 0.5, and the linear regression coefficient was above 10−3, but the breaking extension was weakest and negatively correlated with blending irregularity. Except for breaking extension, the effect of blending irregularities on yarn performance becomes more obvious when there are large differences in fiber linear density and fiber length. This paper reveals the relationship between blending uniformity and yarn performance, to provide a basis for theoretical research on the properties of blended yarns.

Effect of the blending between upland and combing waste on cotton fiber and yarn quality

Blending of cotton wastes with raw materials to produce different textile products has economically and environmentally beneficial. This study was carried out in Cotton Research Institute, Agricultural Research Center. This investigation aimed to study the impact of blending ratio on fiber, mechanical and physical yarn quality properties to find out the optimum blending ratio that achieves the optimum yarn quality properties. For this purpose, fiber properties, mechanical and physical yarn quality properties of ring spun yarns produced from cotton variety Giza95, Delta pine245 cotton variety (upland cotton) combed cotton waste of Extra Fine Giza93 and six different binary blend ratios were studied. Blended samples were spun into 36s, and 40s, carded yarns at constant twist multiplier 4 on ring spinning system. the results showed that fiber properties, Physical and mechanical properties of yarns produced from Giza95 were better than 100% upland cotton, 100% combed cotton waste and the other blended yarns.65% Giza95-35% combed waste of blended samples recorded higher fiber properties(maturity ratio, fiber length, uniformity index, fiber strength and fiber elongation) than all blended samples.Also,the same blended ratio at 36s, yarn count give better lea count product strength, yarn strength, yarn elongation, evenness, imperfections and yarn hairiness compared with all blended yarns followed by 65% combed waste - 35% Giza95.While, the lowest yarn quality properties recorded by The blended yarn of 35% Giza95-65% Delta pine245. Also, it observed that increasing proportion of G95 cotton variety in blended samples led to improve fiber, mechanical and physical yarn properties

Highly Soft, Abrasion-Resistant, and Moisture-Absorbent Wool/PA56 Blended Yarns for Seating Fabrics.

Biobased nylon (PA56) not only has the same physical properties as nylon (PA6/PA66) but its production method is also more environmentally friendly. PA56 fabric has the advantages of moisture absorption, perspiration, high-temperature resistance, and flexibility, which have been widely studied by scientific researchers. Wool has the advantages of beauty, environmental protection, and anti-wrinkle. However, pure wool fabrics have low strength and are easy to shrink when washed, which has always been a problem. Hence, this work adopted the ring spinning method to prepare wool/PA56 blended yarn with wool content of 0, 10, 30, 50, 70, and 100 wt%. Thus, to examine the effects of different blending ratios and twists on yarn performance, PA56 was blended with wool. The results showed that findings indicate that yarn performance is influenced by both yarn twist and blending ratio. The yarn thickens and takes on more linear density as the blending ratio and yarn twist increase. As the wool ratio increases, the yarn's breaking stress and breaking strain decrease. It is obvious that the strength and elongation at break of pure PA56 yarn are 2.09 cN/Dtex and 33.92%, respectively. When the wool content was 100 wt%, the strength and elongation at break of the blended yarn were 0.66 cN/Dtex and 21.15%, respectively. With the amount of wool blending, the yarn hairiness index's H-value initially rises and subsequently falls. The percentage of blended wool reaches 50% at 2.14; less blending might exacerbate the yarn's stem, resulting in neps and unevenness features. The quality of the yarn improves as the blending percentage rises. The yarn has the advantages of resource saving, biodegradability, and environmental friendliness and has a broad application prospect in the automotive interior field.

The prevention and control of hospital-acquired infections remain a significantchallenge worldwide, as textiles used in hospital wards are highly involved in transmission processes. This paper reports a new antibacterial medical fabric used to prepare hospital pillowcases, bottom sheets and quilt covers for controlling and reducing hospital-acquired infections. The medical fabric was composed of blended yarns of staple polyester (PET) and degradable poly(3-hydroxybutyrate co-3-hydroxyvalerate) (PHBV)/polylactic acid (PLA) fibres, which were coated with polylactide oligomers (PLAO), which are environmentally friendly and safe antimicrobial agents with excellent thermal stability in high-temperature laundry. A clinical trial was conducted, with emphasis on the bacterial species that were closely related to the infection cases in the study hospital. After 7 days of use, 94% of PET/PHBV/PLA-PLAO fabric retained <20colony-forming units/100cm2 of the total bacterial amount, meeting hygiene and cleanliness standards. This study demonstrates the potential of fabrics containing polyhydroxyalkanoate oligomers as highly effective, safe and long-lasting antimicrobial medical textiles that can effectively reduce the incidence of hospital-acquired infections.

Optimization of banana fibers degumming by high temperature alkaline method and spinning

Banana fibers are a promising textile resource. However, due to their high gum and lignin content, the development of an efficient degumming method is crucial for their successful utilization. This article researches an improved traditional fiber degumming method using the high temperature alkali method, and the effects of sodium hydroxide concentration, time and temperature on the physical properties of banana fibers were investigated through a single factor experiment. The banana fibers were characterized with FTIR, XRD, SEM and chemical composition. The optimized process parameters of degumming can be achieved. The processing temperature was 140 °C and sodium hydroxide concentration was 10% for 1h. The weight loss and residual gum ratio of the fibers reached 51.84 and 4.13% respectively, the breaking strength was 5.57 cN/dtex, and the crystallinity was increased to 61.33%. These results demonstrate the effectiveness of this new degumming method. Additionally, the optimized banana fibers employed a softening process and were subsequently blended with cotton fibers at a 60/40 ratio for 60tex blended yarn. The breaking strength of the blended yarn was 6.22cN/tex, and the bacterial inhibition ratio was above 70%. This improved method is more suitable for mass production with a high degumming efficiency, and has great potential in the industry. Meanwhile, the excellent antimicrobial properties of banana fibers provide new ideas for development in bedding and clothing applications.

Fabric handling evaluation of woven shirting fabrics by the fabric touch tester

A fabric touch tester is a novel instrument with fabric handling properties. Its principal advantage is that the device has integrated modules for compression, surface friction, and thermal and bending properties. This module integration simplifies the testing process, and provides an efficient measurement method, and a comprehensive physical index. This study focused on woven fabrics for dress shirts. The fabric samples comprised three groups with various yarn compositions – that is, cotton, polyester, and wool. Sample group 1 was composed of cotton, polyester, and blended yarns; sample group 2 mainly compared the effect of twist yarns on the fabric touch; and sample group 3 was composed of wool and blended yarns with polyester. The handling properties were assessed by compression work and the compression recovery rate for the compression attributes. The results revealed that fabric (T100p1) with high twist-level yarns had a higher value of compression work (242.56 gf*mm2), and the texture type may affect the compression characteristics more significantly than the blending ratio. The fabric touch tester can also distinguish small changes in the compression properties of samples (0.43–0.71), the maximum heat flux and surface roughness amplitude for the thermal and surface roughness properties. The results revealed that the maximum heat flux value of all the samples in this study was 1109 Wm−2, the sample C100 using pure cotton yarn had the highest maximum heat flux value (1270 Wm−2). Moreover, the sample W100 with 100% wool fiber yarn had the highest surface roughness amplitude in the warp direction (81 μm) and surface roughness amplitude in the weft direction (67 μm). Finally, the bending average rigidity was used to assess the bending performance of the fabric samples. These fabric touch tester indicators were applied to analyze the fabric handling characteristics of woven shirting fabrics, and perform cross-analysis among samples.

Preparation and performance of stainless steel fiber/Lyocell fiber-blended weft-knitted fabric

Abstract Stainless steel fiber exhibits excellent flame retardancy and melting resistance, but it lacks thermal and moisture comfort. To compensate for these shortcomings, stainless steel fiber was blended with Lyocell fiber in ratios of 0/100, 10/90, 20/80, and 30/70%. The blended yarn was then formed into a single-sided plain stitch fabric of stainless steel fiber and finished with a phosphorus–nitrogen flame retardant. Next, the effects of the blending ratio on the fundamental properties, thermal and moisture comfort, and flame retardancy of the blended yarn and its fabric were studied. Considering these parameters alongside cost, the 10% stainless steel fiber-blended fabric was the optimal choice and showed potential applications for updating and upgrading welding service fabrics.

Statistical analysis of Cotton-Jute blended ratio for producing good quality blended yarn

The present world is focusing on sustainable products. Most of the natural products collected from are environmentally friendly. In the textile sector the main raw material is fiber. Most textile products are made from the natural cotton fibers. But because of the shortage of this fiber, most of the researchers are looking forwards to other sources of natural fibers. Here in Bangladesh the natural jute fiber is available and the textile industries are making jute products but the jute products are comparatively lower price than cotton products. That's why some factories are making cotton-jute blended yarn to minimise the cost and increase the product's quality and appearance. Here in this research work, it was tried to identify the best cotton-jute blended ratio for producing good quality yarn. 80C-20 J, 60C-40 J and 40C-60 J blended ratios are compared with 100 C and 100 J yarn to analyse the results. The CV m%, Thick/Km +50 %, Neps/Km +200 %, IPI, RKM and Elongation% of blended yarns are evaluated and compared the results between the ratios. After that the yarn quality index (YQI) was calculated to identify the ratio which indicates a relation between yarns strength, elongation% and CVm. The other quality index was fiber quality index (FQI) which indicates a relation between fibers strength, fiber mean length, elongation% and fiber fineness. One way ANOVA was applied to see the significance level between the independent variables. Box plot was applied to see the visual effect of statistical analysis at the same time the regression results show the impact of cotton-jute ratio with an equation, through which it was easy to identify the perfect ratio. It was found that higher percentage of cotton and lower percentage of jute fiber blended yarn shows good results than others. The products which were made from the ratios were shown good results for their different use of purposes.

Sustainable yarns and fabrics from tri-blends of banana, cotton and tencel fibres for textile applications

Millions of tons of banana pseudo-stem are readily available annually, making it a sustainable resource for banana fiber. Banana fibres possess inherent mechanical strength and anti-microbial properties, accompanied by stiffness and a harsh feel that undermine their full utilization in textiles. An effort was made in this study to create eco-friendly yarns and fabrics by combining banana fiber reclaimed from banana agro-waste with cotton and regenerated cellulosic (Tencel) fiber in varying blend ratios. The negative influence attached to banana fibre due to its chemical softening was overcome by boiling it in distilled water. The softened banana fibres were evaluated based on feel, strength, and weight loss. Three blend ratios, i.e., 10%, 20%, and 30% of banana fibre by weight, were selected to produce Banana: Cotton: Tencel blended yarns. Yarn characterizations revealed excellent mechanical properties as compared to the benchmark Cotton: Tencel 50:50 yarns. The yarn bundle strength and single yarn strength obtained in the case of 20% banana fibre blended yarn were approximately 11% and 8.62% higher than the Cotton: Tencel 50:50 blended yarns and 22.90% better in the yarn quality index analysis, respectively. Fabrics were formed using the said yarns on an industrial loom. Banana fibre blended fabrics exhibited a 6.61% higher tear strength, 18.8% more air permeability, 20% more elongation, and 12% higher tensile strength as compared to the Cotton: Tencel blended fabrics. The provided findings in this study propose that following this design approach during textile manufacturing will lead to more environmental and economic gains with high performance.

Comprehensive performance evaluation based on electromagnetic shielding properties of the weft-knitted fabrics made by stainless steel/cotton blended yarn

Abstract Electromagnetic shielding (EMS) fabric is an effective way to prevent electromagnetic (EM) radiation. However, the research about mechanism analysis of the fabrics’ structure, EM wave (EMW) incident direction, and EMW frequency on the EMS properties of knitted fabrics is discordant at present. Meanwhile, researchers are focused on improving the EMS efficiency of the fabric but rarely discussed the thermal-wet comfort of the fabric. Therefore, in this study a series of weft-knitted fabrics within stainless steel/cotton (30/70) blended yarns were knitted, and the effects of EMW incident direction, stitches, loop lengths, and frequency on EMS effectiveness (EMSE) were analyzed. Meanwhile, the EMS property, warmth retention property, air permeability, moisture permeability, and bursting strength were selected as the evaluation index to evaluate the comprehensive properties of the fabrics by fuzzy mathematics. The results showed that all factors had different degrees of influence on EMSE, and the weft inlay stitch had both the functionality and thermal-wet comfort, which was excellent EMSE in knitted fabric. These results are expected to provide a reference to the design of EMS weft-knitted fabrics.

Escalating the use of jute (Robi-1)-cotton blended yarn rather than entirely made of cotton yarn

The process of blending involves the mixing of two different fibers to achieve the desired percentage. Various compositions, lengths, diameters, or colors may be intermingling to produce a blended yarn in a ring spinning system. This system entails the combination of different fibers lots into a homogeneous mass before spinning the mass into a staple fiber yarn. Typically, BJRI Tossa Pat-8 (Robi-1) and cotton fibers are combined to create jute-cotton blended yarn. Jute can be utilized in various ways, which is one approach to blending yarn. The jute-cotton blended yarn was produced in a ratio of 30% and 70%. Both jute-cotton blended yarn and totally cotton yarn were produced on a cotton spinning line using a ring frame. The physical characteristics of both yarns, such as count, yarn Lea strength, and CSP were measured. The average count of fully cotton yarn and jute-cotton blended yarn was found to be roughly equal at 12.16 and 11.82, respectively. However, the yarn lea strength and CSP of both samples, which are significantly different from one another, were 232 lb, 140 lb, and 2835, 1670, respectively. Along with entirely made of yarn, blended yarn also exhibits consistency in terms of CV%, SD, and PMD. This study compared the physical characteristics of both yarns after Robi-1 was first introduced for the blending process with cotton to produce a jute-cotton blended yarn.
