This study investigates the impact of yarn count and stitch length of 100% cotton knitted fabrics. 1 × 1 ribs structured fabrics were used in this research work. The stitch length 2.50 mm, 2.52 mm, 2.60 mm, 2.70 mm, 2.80 mm and 2.96 mm were used of the yarn count of 26Ne, 28Ne and 36Ne. The areal densities of the grey fabrics were in various amounts. The impacts of yarn count and stitch length were measured concerning pilling resistance, abrasion resistance, and shrinkage and tightness factor. The result showed that the fabric pilling grade decreased while number of cycle increased. Abrasion resistance decreased but length wise shrinkage increased despite the fact that the stitch length increased. The results also exposed that the tightness factor of the fabric increased with the increase of the stitch length in both dyeing and washing state and finished state compared to grey state for the yarn count 26Ne and homogeneous result not found for yarn count 28Ne and 36 Ne. Evaluation of Impact of Yarn Count and Stitch Length on Pilling, Abrasion, Shrinkage and Tightness Factor of 1 × 1 Rib Cotton Knitted Fabrics
研究了纱线支数和针长对全棉针织物编织性能的影响。本研究采用1 × 1肋结构织物。纱支分别为26Ne、28Ne和36Ne,针长分别为2.50 mm、2.52 mm、2.60 mm、2.70 mm、2.80 mm和2.96 mm。坯布的面密度大小不一。考察了纱线支数和针长对织物抗起球性能、耐磨性和收缩紧性的影响。结果表明,织物起球等级随着循环次数的增加而降低。耐磨性下降,但长度收缩增加,尽管线长增加。结果还表明,纱线支数为26Ne时,织物在染洗状态和成品状态下的紧度系数均随针长增加而增加,而纱线支数为28Ne和36ne时,织物的紧度系数均不均匀。纱线支数和针长对1 × 1罗纹棉针织物起球、磨损、收缩和紧性系数影响的评价

The importance of sulfur dyeing of cellulosic fibers, particularly cotton, is realized economically throughout the dyeing industry. At the present time, dyeing with sulfur dyes requires the use of various auxiliaries, many of which have adverse effects on the environment. The most damaging of these is the reducing agent sodium sulphide, required to reduce the dye molecules to a water-soluble leuco form to enable adsorption and diffusion into the fiber. In this study, attempts have been made to replace the sodium sulfide used within the sulfur dyeing process with a variety of environmentally friendly reducing sugars. The redox potential of various hexose and pentose monosaccharide’s and reducing disaccharides was recorded and compared. Subsequently, cotton was dyed with the world's most important sulfur dye, C. I. Sulfur Black 1, using the reducing sugars under alkaline conditions, and compared to dyeing secured by employing commercial sulfide reducing agents. It was observed that reducing sugars gave comparable, and in many cases superior, color strength and wash fastness results, with respect to the commercial sulfide-based reducing agents, which still account for the vast majority of sulfur dyeing processes and that pose significant environmental concern. Employment of reducing sugars in sulfur dyeing could provide a sustainable, nontoxic, biodegradable, cost-effective alternative to sodium polysulfide and sodium hydrogen sulfide.

纤维素纤维,特别是棉花的硫染色的重要性在整个染色工业中都得到了经济上的认识。目前,用硫染料染色需要使用各种助剂,其中许多助剂对环境有不利影响。其中最具破坏性的是还原剂硫化钠,它需要将染料分子还原为水溶性的白色形式,使其能够吸附和扩散到纤维中。在本研究中,尝试用各种环保的还原糖代替硫染色过程中使用的硫化钠。记录并比较了各种己糖、戊糖单糖和还原性双糖的氧化还原电位。随后,用世界上最重要的硫染料c.i.硫黑1在碱性条件下使用还原糖染色棉花,并与使用商业硫化物还原剂染色进行比较。据观察,与商业硫化物基还原剂相比,还原糖具有相当的颜色强度和洗涤牢度结果,而且在许多情况下优于商业硫化物基还原剂,而商业硫化物基还原剂仍然占硫染色工艺的绝大多数,并造成重大的环境问题。在硫染色中使用还原糖可以为多硫化钠和硫化氢钠提供一种可持续的、无毒的、可生物降解的、具有成本效益的替代品。通讯作者:Mebrahtom Teklehaimanot,纺织工程系,阿克苏姆大学,阿克苏姆,埃塞俄比亚,E-mail: mebreat@gmail.com2018年11月30日录用;引用本文:Teklehaimanot M, Amsalu T(2018)糖水解对硫黑棉织物染色的影响。[J] .纺织工程学报,8(3):394。Copyright:©2018 Teklehaimanot M, et al. doi: 10.4172/21658064.1000384这是一篇根据知识共享署名许可协议发布的开放获取文章,该协议允许在任何媒体上不受限制地使用、分发和复制,前提是要注明原作者和来源。

The cost of making apparel fabrics for garment manufacturing is very high because of their conventional manufacturing processes and new methods/processes are being constantly developed for making fabrics by unconventional methods. With the advancements in technology and the availability of the innovative fibre, durable nonwoven fabrics by using the hydroentanglement process that can compete with the woven fabrics in terms of their aesthetic and tensile properties are being developed. In the work reported here, the hydroentangled nonwoven fabrics were developed through a hybrid nonwoven manufacturing processes by using fibrillated Tencel® and bi-component (sheath/core) polyethylene/polyester (PE/PET) fibres, in which the initial nonwoven fabrics were prepared by the needle-punching method followed by hydroentanglement process carried out at optimal pressures of 50 to 250 bars. The prepared fabrics were characterised according to the British Standards (BS 3356:1990, BS 9237:1995, BS 13934-1:1999) and the attained results were compared with those for a standard plain-weave cotton, polyester woven fabric and commercially available nonwoven fabric (Evolon®). The developed hydroentangled fabrics showed better drape properties owing to their flexural rigidity of 252 mg.cm in the MD, while the corresponding commercial hydroentangled fabric displayed a value of 1340 mg.cm in the MD. Tensile strength of the developed hydroentangled fabrics showed an approximately 200% increase than the commercial hydroentangled fabrics. Similarly, the developed hydroentangled fabrics showed higher properties in term of air permeability, such as the developed hydroentangled fabric exhibited 448 mm/sec and Evolon fabric exhibited 69 mm/sec at 100 Pa pressure. Thus for apparel fabrics, the work combining the existing methods of nonwoven production, provides additional benefits in terms of cost, time and also helps in reducing the carbon footprint for the apparel fabric manufacture.
由于传统的制造工艺,制造服装面料的成本非常高,而采用非常规方法制造面料的新方法/工艺正在不断开发。随着技术的进步和创新纤维的可用性,利用水缠结工艺的耐用非织造布在美学和拉伸性能方面可以与机织物竞争。在这里报道的工作中,通过混合无纺布制造工艺,使用纤化天丝®和双组分(护套/芯)聚乙烯/聚酯(PE/PET)纤维,开发了水缠结非织造布,其中最初的非织造布是通过针刺方法制备的,然后在50至250巴的最佳压力下进行水缠结过程。根据英国标准(BS 3356:1990, BS 9237:1995, BS 13934-1:1999)对所制备的织物进行了特性测定,并将所得结果与标准的平纹棉、聚酯机织织物和市售无纺布(Evolon®)进行了比较。所研制的水缠织物抗弯刚度为252mg,具有较好的悬垂性能。而相应的商业水缠织物显示的值为1340 mg。开发的水缠织物的抗拉强度比商用水缠织物提高了约200%。同样,开发的水缠织物在透气性方面表现出更高的性能,如开发的水缠织物在100 Pa压力下的透气性为448 mm/秒,Evolon织物的透气性为69 mm/秒。因此,对于服装面料,结合现有的非织造布生产方法,在成本、时间方面提供了额外的好处,也有助于减少服装面料制造的碳足迹。

In this study, the effects of ozone desizing treatment on the water absorption and tear strength of 100% cotton terry fabrics were investigated and the results were compared with those obtained by combined conventional desizing and scouring treatment. For this purpose, ozone dose, ozonation time and pile yarn length were considered as the factors. Ozone desizing process was carried out for four different terry fabric having different pile yarn lengths at two different ozone dose (500 and 1000 mL/minute), four different ozonation time (5, 15, 30, 45 minute). It was found that when the ozonation time or ozone dose increased the tear strength and abrasion resistance decreased, but the effect of ozone dose was remarkable on long ozonation duration. Also, it was determined that the combined conventional desizing and scouring process damaged the terry fabric much less than ozone desizing process.
研究了臭氧退浆处理对100%纯棉毛圈织物吸水性和撕裂强度的影响,并与常规退浆和精练联合处理的结果进行了比较。为此,考虑了臭氧用量、臭氧化时间和成纱长度等因素。在两种不同臭氧剂量(500和1000 mL/min)和四种不同臭氧化时间(5、15、30、45 min)下,对4种不同绒毛纱长度的毛圈织物进行了臭氧退浆工艺。结果表明,随着臭氧化时间和臭氧剂量的增加,材料的撕裂强度和耐磨性降低,但臭氧剂量对臭氧化持续时间的影响显著。同时,确定了常规退浆与精练联合退浆对毛圈织物的损伤要比臭氧退浆小得多。

This paper investigates the seam strength and efficiency along with, how fabric structural and sewing parameters as: weave design, weft density and seam type effect the strength and efficiency of seams. Six cotton fabrics having three weave designs and two weft densities were developed and sewn by five different seam sub-types. The lockstitch sewing machine was used. Strength of fabrics and seams were tested on Instron tensile machine. Assessments of all results were conducted with respect to weave design, weft density and seam sub-types separately by using a factorial design variance analysis. The study found that weave design significantly affect the seam strength and its efficiency in both directions. The direction of stitch is most important for seam efficiency. Moreover, the increasing trend was found towards seam strength and its efficiency by increasing the weft density. Each seam sub-type has its own strength values relative to each type of weave design and weft density. This research emphasizes only on cotton fabric with selected fabric structural parameters and seam sub-types. The presented conclusion is effective only this group of parameters and cannot be used inclusively. Thus far, the effect of different fabric structural parameters with seams has not been studied previously. This concern has been fulfilled in this research.
本文研究了织物的结构和缝纫参数,如组织设计、纬纱密度、缝型等对接缝强度和效率的影响。开发了六种具有三种组织设计和两种纬密度的棉织物,并采用五种不同的缝型进行缝制。使用了平缝机。在Instron拉伸机上对织物的强度和接缝进行了测试。采用因子设计方差分析分别对织物设计、纬纱密度和缝型进行评估。研究发现,编织设计对接缝强度和接缝效率都有显著影响。线迹方向是影响缝迹效率的最重要因素。此外,增加纬纱密度对接缝强度和效率有提高的趋势。每一种缝型都有自己的强度值,与每一种编织设计和纬纱密度有关。本研究仅针对选定织物结构参数和缝型的棉织物进行研究。所得结论仅对这组参数有效,不能综合使用。到目前为止,还没有研究不同织物结构参数对接缝的影响。这一关注在本研究中得到了实现。

Knit spacer fabrics have gained popularity in varied functional applications. Some important types of these fabrics are highlighted. One such is in medical applications, wherein the weft knit spacer fabrics have been attempted in treating pressure ulcer. The results show that the air permeability, thermal conductivity and water vapor permeability of weft knitted spacer fabrics are comparable with the existing wound dressings. The compressional resistance and resilience of them are good for providing protection as wound dressing. The absorbency of them is somewhat better than some wound dressings; however, they are suitable for pressure ulcer wounds with no heavy extrude. Warp knit spacer fabrics offer a better option over polyurethane foam in car seats owing to their advantages such as better recovery to compression, thermal properties and breathability. Flat-knitted spacer fabrics offer a strong potential for complex shape preforms, which could be used to manufacture composites with reduced waste and shorter production times. This article focuses on the improved strength and stiffness of woven three-dimensional (3D) spacer fabrics used in fiber reinforced plastics. The spacer fabrics were manufactured using E-glass/polypropylene (GF/PP) hybrid yarns and are intended for lightweight engineering applications. Flat-knitted spacer fabrics offer a strong potential for complex shape preforms, which could be used to manufacture composites with reduced waste and shorter production times.
针织间隔织物在各种功能应用中得到了广泛的应用。重点介绍了这些织物的一些重要类型。其中一个是在医疗应用中,其中纬编间隔织物已被尝试用于治疗压疮。结果表明,纬编间隔织物的透气性、导热性和透气性与现有伤口敷料相当。它们的抗压缩性和回弹性对伤口敷料有很好的保护作用。吸收性比一些创面敷料稍好;然而,它们适用于没有沉重挤压的压疮伤口。经编间隔织物在汽车座椅中提供了比聚氨酯泡沫更好的选择,因为它们具有更好的压缩恢复、热性能和透气性等优点。平编间隔织物为复杂形状预成型提供了强大的潜力,可用于制造复合材料,减少浪费,缩短生产时间。本文主要研究了提高纤维增强塑料中机织三维(3D)间隔织物的强度和刚度。间隔织物是由e -玻璃/聚丙烯(GF/PP)混合纱线制造的,用于轻量化工程应用。平编间隔织物为复杂形状预成型提供了强大的潜力,可用于制造复合材料,减少浪费,缩短生产时间。

In this study, the bamboo fibre bundles (CAN retted fibre bundles) have been treated with sodium hydroxide at different processing conditions, in combination with potassium hydroxide and chlorine containing agent sodium chlorite solution. The purpose of this study was to develop efficient method for the extraction/loosening of bamboo fibres for further textile applications, therefore, lignin content, tensile strength, weight loss, moisture content, whiteness and yellowness indices were measured. Lignin content analysis of the extracted fibre bundles showed that there was a remarkable reduction in lignin content after these treatments. Scanning electronic microscopy of the treated bamboo fibre bundles showed removal of short elementary fibres from their surfaces in appropriate amount which further improved their overall physical properties of treated bamboo fibres.
本研究用氢氧化钠在不同的工艺条件下,与氢氧化钾和含氯剂亚氯酸钠溶液混合处理竹纤维束(CAN纤维束)。本研究的目的是为进一步的纺织应用开发有效的提取/松动竹纤维的方法,因此,测量了木质素含量,拉伸强度,重量损失,水分含量,白度和黄度指标。对提取纤维束的木质素含量分析表明,这些处理显著降低了木质素含量。处理后的竹纤维束的扫描电镜显示,从其表面去除适量的短初级纤维,进一步改善了处理后的竹纤维的整体物理性能。
