Silk/Rayon Webs and Nonwoven Fabrics: Fabrication,Structural Characteristics,and Properties

Silk is a naturally occurring material and has been widely used in biomedical and cosmetic applications owing to its unique properties, including blood compatibility, excellent cytocompatibility, and a low inflammatory response in the body. A natural silk nonwoven fabric with good mechanical properties was recently developed using the binding property of sericin. In this study, silk/rayon composite nonwoven fabrics were developed to increase productivity and decrease production costs, and the effect of the silk/rayon composition on the structure and properties of the fabric was examined. The crystalline structure of silk and rayon was maintained in the fabric. As the silk content increased, the porosity and moisture regain of the silk/rayon web and nonwoven fabric decreased. As the silk content increased, the maximum stress of the web and nonwoven fabric increased, and the elongation decreased. Furthermore, the silk/rayon web exhibited the highest values of maximum stress and elongation at ~200 °C. Regardless of the silk/rayon composition, all silk/rayon nonwoven fabrics showed good cytocompatibility. Thus, the silk/rayon fabric is a promising material for cosmetic and biomedical applications owing to its diverse properties and high cell viability.     

Tensile and elastic behavior of tencel continuous filaments

Tencel is a regenerated cellulose fiber produced using an environmentally‐responsible dry‐jet wet‐spinning process, which contributes to its excellent mechanical properties. In this study, the tensile properties of Tencel continuous filaments are characterized and the effect of twist on mechanical properties, including breaking load and extension, are considered. Peak strength was obtained in Tencel filaments of 140 t m^?1. The elastic behavior of Tencel monofilament was observed by assessing the recovery from strain‐induced energy and the elastic recovery was found to be low. Along with time dependency, Tencel has the ability to stabilize its deformed state by forming new crosslinks, and this influences the elastic behavior. In simple extension cycles, the same low elasticity was observed. Cumulative extension cycles were also performed to characterize the behavior of filaments subjected to repeated strain and to determine the resultant hysteresis effects. Permanent elongation was observed at 2% imposed strain, which suggests that the filament has low extensibility. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 99: 1496–1503, 2006

聚乳酸/天丝混纺纱混纺比与力学性能测试分析

聚乳酸(PLA)和天丝(Tencel)混纺纱的性能除了受到纤维本身和纱线捻度的影响,也跟纱线混纺比有很大关系。实验以不同混纺比的PLA/Tencel混纺纱为基本素材,进行力学性能测试,通过实验数据的分析,探索纱线力学性能随混纺比变化的规律。结果表明,标准状态下,混纺纱的强度随PLA质量分数的减少先减小后增大,混纺比在质量分数PLA60%/Tencel40%时,纱线强度降到最低点;混纺纱的湿强度随混纺比的变化趋势与干强度基本一致,临界混纺比相差也不大;混纺纱弹性回复率随PLA质量分数的减少,先增大后减小,PLA质量分数为70%时,纱线弹性回复率最大,纯Tencel纱线弹性回复率最小。     

Mechanism of crosslinking Tencel woven fabric for superior easy‐care properties and analysis using fluorescence microscopy

A crosslinking treatment to impart easy‐care properties to Tencel fabric has been investigated, using dimethyloldihydroxyethylene urea (Reaktant DH) as crosslinking agent and magnesium chloride hexahydrate as catalyst. Nonconventional treatment techniques such as “flash curing,” “moist curing,” “pad‐batch‐cure,” and “pad‐dry‐dry steam cure” are used to facilitate better penetration of crosslinking monomer into the fiber interior. Easy‐care properties of Tencel fabrics using these techniques are evaluated and compared with those treated with resin monomer using conventional pad‐dry‐cure process. Analysis of treated fabric using a fluorescent labeling technique and image analysis shows that nonconventional techniques significantly improve the penetration of crosslinking agent. The results further suggest that these techniques can be used to improve abrasion resistance and fabric handle of Tencel woven fabric. © 2006 Wiley Periodicals, Inc.

Ink‐jet printing process for lyocell and cotton fibres. Part 2: The relationship of colour strength and dye fixation to ink penetration

The colour appearance on ink‐jet printed textiles is influenced by a range of factors, including the chemical and physical nature of the fibre, dye–fibre affinity, pretreatment and fabric structure. Regression analyses were conducted to study the correlation between colour strength, fixation and ink penetration obtained by ink‐jet printing lyocell fibres (standard Tencel and Tencel A100) and cotton with an ink based on a monofunctional reactive red dye. The fixation was highest on Tencel A100, followed by standard Tencel and then cotton, while colour strength was highest on standard Tencel followed by cotton and Tencel A100. A linear relationship between colour strength and ink penetration was found with cotton, indicating greater dependence of depth of shade on ink penetration than on standard Tencel and Tencel A100 fabrics, where the interrelationships were more complex, but of low statistical significance. A schematic representation is proposed illustrating the mechanism of ink penetration into pretreated fibres, which provides a reasonable interpretation of the events occurring as dye penetrates into and fixes onto the fibres.     

The quasi‐yarn‐dyed effect: triple dyeing of woven polyester/cationic dyeable polyester/viscose rayon blend fabrics by chemical treatments in the laboratory and on a pilot and an industrial scale

The aim of this study was to carry out triple dyeing of woven polyester/cationic dyeable polyester/viscose rayon blend fabrics with the required colour fastness and physical properties. The feel and final appearance of the fabric were achieved by partial removal of the viscose rayon moiety of the fabric through optimised causticisation treatments. The results of the triple dyeings obtained from laboratory and small‐scale experiments were successfully scaled up in authentic processing equipment. The final product, which has a yarn‐dyed effect, readily satisfied the requirements related to the colour fastness and physical properties.

Assessment of uniformity of fibre coloration in Tencel woven fabrics dyed using reactive dyes

Weave structure and fabric density has an influence on dye penetration. The uniformity of dyeing, expressed as the uniformity of fibre coloration, of Tencel woven fabrics comprised of different weave structures, was assessed. The fabrics were dyed by exhaust and continuous dyeing methods using selected reactive dyes. Cross‐sectional images were captured and then given a rating 1–5 with respect to the depth of the fibre filaments of the yarn of the woven fabric. The images were assessed both subjectively and objectively. The uniformity of fibre coloration was expressed in terms of the standard deviation, mean value and histogram analysis such as dispersion and bandwidth. Objective assessment of uniformity of fibre coloration is a more accurate and quicker method than visual assessment and can be used to assess the uniformity of fibre coloration of woven and knitted fabrics dyed by any class of dyes. Improvement of the uniformity of fibre coloration of Tencel fabrics of various weave structures by causticisation of the fabrics and by modification to the padding process was investigated.
