Our aim was to confirm earlier studies showing tcPO2 to be higher under clothing made with polyethylene terephalate (PET) fabric containing ceramic particles (CEL) compared to standard PET fabric. In previous studies PET garments were donned first to avoid possible persistent effects from ceramic particles. This study randomized donning sequence to avoid bias.

Methods: Subjects were randomized to don either PET shirts first (PETF n=73) or CEL first (CELF n=80), switching garments after 90 minutes. Skin temperature (ST), arterial oxygen saturation (O2sat), and tcPO2 were measured every 30 minutes.

Results: Baseline ST and O2 sat were nearly identical in the two groups. Baseline tcPO2 was modestly higher in the CELF group than with PETF: 66.4 ± 18.9 vs. 63.9 ± 18.8 mmHg (n.s). Independent of donning sequence, tcPO2 measurements 90 minutes after wearing CEL were 6.7% higher than after 90 minutes wearing PET (p<0.0003). Sequence analysis found tcPO2 in PETF subjects to gradually rise before and after switching garments, but tcPO2 fell immediately after switching garments in CELF subjects. PETF baseline O2sat of 98.1 ± 1.3 increased insignificantly after 90 minutes, and then increased further to 98.6 ± 0.8 after wearing CEL ninety minutes (p=0.0001). CELF baseline O2sat of 97.9 ± 1.7 increased to 98.5 ± 1.1 90 minutes after donning CEL (p=0.0002) and fell to 98.3 ± 1.0 ninety minutes after switching to PET (p=0.0033).

Conclusions: The ability of ceramic-embedded fabric to induce higher tcPO2 measurements is not due to sequence bias.

我们的目的是证实早期的研究表明,与标准PET织物相比,用含有陶瓷颗粒(CEL)的聚乙烯对苯二甲酸酯(PET)织物制成的衣服中tcPO2的含量更高。在之前的研究中,人们首先穿上PET服装,以避免陶瓷颗粒可能产生的持续影响。本研究随机化穿衣顺序以避免偏倚。方法:受试者随机选择先穿PET衬衫(PETF n=73)或先穿CEL衬衫(CELF n=80), 90分钟后换衣服。每30分钟测量皮肤温度(ST)、动脉血氧饱和度(O2sat)和tcPO2。结果:两组的基线ST和O2 sat几乎相同。基线tcPO2在CELF组略高于PETF组:66.4±18.9 mmHg vs. 63.9±18.8 mmHg (n.s)。与穿衣顺序无关,穿CEL后90分钟的tcPO2测量值比穿PET后90分钟高6.7% (PETF组p2在换服前后逐渐升高,而CELF组tcPO2在换服后立即下降)。PETF基线O2sat为98.1±1.3,佩戴90分钟后无显著升高,佩戴90分钟后进一步升高至98.6±0.8 (p=0.0001)。CELF基线O2sat在穿上CEL后90分钟由97.9±1.7升至98.5±1.1 (p=0.0002),而在换上PET后90分钟降至98.3±1.0 (p=0.0033)。结论:陶瓷嵌入织物诱导较高tcPO2测量的能力不是由于序列偏差。

Butane-tetra-carboxylic acid (BTCA) and sodium hypophosphite (SHP) were added into cellulose spinning solution. The cross-linked regenerated cellulose fibers were prepared by spinning the solution into a coagulation bath of distilled water and then cured at high temperature. The optimum conditions were obtained according to the single factor experiments. The properties and structure of the fibers were investigated. FTIR and XRD show that the cross-linked fibers were prepared successfully and the crystal form of the fibers remain the same before and after cross-linked. The results indicate that the regenerated cellulose fibers prepared in this study possess more excellent wrinkle recovery ability and wash durability than those treated by finishing process.

Introduction and application of eco-friendly natural dyes on textile coloration have significant importance on the reduction of environmental pollution. Due to this reason many scientists are doing research work on natural dye application on textile materials in the past few years. Having this in mind, this investigation was concerns with the dyeing of silk fabric with colorant extracted from bark of Hambo Hambo (Cassia singueana) plant in the presence of Aloe Vera as natural mordant. Aqueous extraction method was employed for obtaining coloring components. The extraction parameters have been studied and optimum dye extraction condition was examined under UV-Visible spectroscopy which recorded its maximum absorption as (A=3.9). Silk fabric was dyed with the extracted natural dye without mordant and in the presence of synthetic and natural mordants using different mordanting techniques. The color strength, CIE L*A*B* values and fastness properties of the dyed samples were analysed according to the international standards. The Washing fastness, rubbing fastness and light fastness obtained from the directly dyed without mordant and dyed using with Aloe Vera and Copper sulphate (CuSO4.5H2O) mordants was almost similar which was recorded in the range of very good to excellent. The results of this investigation led to the conclusion that there is possibility of dyeing of silk fabric using natural dye extracted from Cassia singueana plant directly without mordant and dying in the presence of Aloe Vera with acceptable range of fastness properties of dyed silk fabric.
环保型天然染料在纺织品染色中的引入和应用对减少环境污染具有重要意义。因此,近年来许多科学家对天然染料在纺织材料上的应用进行了研究。考虑到这一点,本研究关注的是从Hambo Hambo(决明子)植物树皮中提取的着色剂在芦荟作为天然媒染剂存在下对丝绸织物的染色。采用水提法提取染色成分。对提取工艺进行了研究,并在紫外可见光谱下确定了最佳提取条件,其最大吸光度为(A=3.9)。用提取的天然染料对真丝织物进行无媒染剂染色,在合成媒染剂和天然媒染剂的存在下,采用不同的媒染剂染色技术。按照国际标准对染色样品的色强、CIE L*A*B*值和牢度性能进行了分析。无媒染剂直接染色与用芦荟和硫酸铜(CuSO4.5H2O)媒染剂染色所得的洗涤牢度、摩擦牢度和光牢度基本相同,均在极好至优异的范围内。研究结果表明,用决明子提取的天然染料直接染色真丝织物是可行的,无需媒染剂,在芦荟的存在下染色,染色真丝织物的牢度性能在可接受的范围内。

The apparel fabric manufacturing is a growing sector of the global textile industry and the fabrics used in this market are mainly produced by the conventional methods such as weaving and knitting processes. These methods of making apparel fabrics are length and costly. However, because of the advancements in nonwoven technology, nonwoven fabrics are finding a niche market in the clothing industry because of its cost effectiveness and high speeds of nonwoven production processes. We have carried out an extensive study on the development of apparellike nonwoven fabrics. The resultant fabric showed improved drape, hand, durability and thermophysiological comfort characteristics than the reference samples for apparel applications. Results of the study also showed that the developed nonwoven fabrics showed nearly 200% higher tensile strength than the reference nonwoven fabrics. Furthermore, it also showed improved air permeability, for example, the resultant nonwoven fabric exhibited 500% higher air permeability value as compared with the Evolon fabric at 100 Pa pressure. Thus the results of the study indicate that the resultant nonwoven fabrics may be used in a wide range of apparel applications, which can lead to additional benefits in terms of cost and time.

服装面料制造是全球纺织工业中一个不断增长的部门,这个市场中使用的面料主要是通过织造和针织等传统方法生产的。这些制造服装面料的方法既冗长又昂贵。然而,由于非织造技术的进步,非织造布由于其成本效益和非织造生产过程的高速而在服装行业中找到了一个利基市场。我们对服装类非织造布的开发进行了广泛的研究。与服装应用的参考样品相比,所得织物具有更好的悬垂性、手感、耐久性和热生理舒适性。研究结果还表明,开发的非织造布的抗拉强度比参考非织造布高出近200%。此外,它还显示出改善的透气性,例如,所得的无纺布在100 Pa压力下的透气性值比Evolon织物高500%。因此,研究结果表明,所得的非织造布可以广泛用于服装应用,这可以在成本和时间方面带来额外的好处。服装应用非织造布的发展Cheema MS1*, Anand SC1 and Shah TH2 1英国博尔顿大学材料研究与创新研究所2巴基斯坦国立纺织大学*通讯作者:Cheema MS,英国博尔顿大学材料研究与创新研究所,博尔顿迪恩路,BL3 5AB,英国,电话:44-7735564985;邮箱:chscheema@gmail.com 2018年10月16日收稿;2018年11月19日录用;引用本文:Cheema MS, Anand SC, Shah TH(2018)非织造布在服装应用中的发展。[J] .纺织工程学报,8(3):382。doi: 10.4172/21658064.1000382版权所有:©2018 Cheema MS等。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。

Modification of Cotton Fibre with Functionalized Silane Coupling Agents Vinyltriethoxysilane and Aminopropyltriethoxysilane 功能化硅烷偶联剂乙烯基三乙基氧基硅烷和氨基丙基三乙基氧基硅烷改性棉纤维

Cotton fibre was modified by condensation polymerization with functionalized silane coupling agents like vinyltriethoxysilane (VTES) and aminopropyltriethoxysilane (APTES) in an ethanol/water medium. The modification of cotton fibre enhanced the tensile properties, softness properties, water repellence and wrinkle recovery, due to higher flexibility of the Si-O bond between the silane coupling agents and the cotton fibre. The ability of the modified cotton fibre to swell decreased in an aqueous solution, which affects the overall chemical suitability of the fibre. The optimized condition in which to modify cotton fibre was a monomer concentration of: 500% for VTES and 600% for APTES (depending on the weight of the fibre); pH 3.5 for VTES and 5 for APTES: ethanol-water ratio 40:60 for VTES and 80:20 for APTES; reaction time of 90 minutes both for VTES and APTES at room temperature (30°C), in the fibre-liquor ratio of 1:50. Swelling of the modified cotton fibre decreased in polar solvents and increased in nonpolar solvents. Fourier transform Infrared spectroscopy was used to identify the incorporation of siliconcontaining molecules. Energy Disperse X-ray analysis determined the quantities of atomic silicon which directly reflects its valence bond with organic moieties. Scanning electron microscopy and thermogravimetric analysis were used to investigate the surface morphology and thermal behavior of the modified fibre, respectively. Examination of the dyeability of washed and modified cotton fibres, dyed with Reactive Brown-10 and Reactive Orange-14, showed that the absorption of dye by modified fibre was comparatively higher than that of raw cotton fibre.
以乙烯基三乙基氧基硅烷(VTES)和氨基丙基三乙基氧基硅烷(APTES)为偶联剂,在乙醇/水介质中对棉纤维进行缩聚改性。由于硅烷偶联剂与棉纤维之间的Si-O键具有更高的柔韧性,因此改性棉纤维的拉伸性能、柔软性能、拒水性和抗皱回复率均有所提高。改性棉纤维在水溶液中的膨胀能力下降,影响纤维的整体化学适应性。改性棉纤维的最佳条件是:VTES单体浓度为500%,APTES单体浓度为600%(取决于纤维的重量);VTES的pH为3.5,APTES的pH为5:VTES的乙醇水比为40:60,APTES的乙醇水比为80:20;在室温(30℃)下,纤维液比1:50,VTES和APTES反应时间均为90分钟。改性棉纤维在极性溶剂中溶胀减小,在非极性溶剂中溶胀增大。傅里叶变换红外光谱法用于鉴定含硅分子的掺入。能量分散x射线分析确定了原子硅的数量,这直接反映了它与有机部分的价键。利用扫描电镜和热重分析分别对改性纤维的表面形貌和热行为进行了研究。用活性棕-10和活性橙-14染色水洗和改性棉纤维的可染性测试表明,改性纤维对染料的吸收率相对高于原棉纤维。

In this study the energy absorption response and load carrying capability of Bombyx mori (B. mori) natural silk fibre/Epoxy composite cylindrical tubes under an axial quasi-static compression was investigated. The composite tubes were prepared using mandrel assisted hand lay-up technique. The tube was fabricated using 24 layers of B. mori natural silk fibre, fully wetted with epoxy matrix. The tube was then cut into varied lengths of 50 mm, 80 mm, and 120 mm, respectively. Three specimens were tested in each category. The experimental results were analysed by measuring maximum peak load (Pmax), specific absorbed energy (SAE), and total energy absorption (TE) as a function of tube length. Findings show results being varied according to tube length in unpredictable manners. Failure fragmentation of the tubes was analysed from photographs obtained during the test using high resolution camera, which showed micro cracks induced by compression load as the predominant source of failure.
研究了家蚕天然丝纤维/环氧树脂复合材料圆柱形管在轴向准静态压缩下的吸能响应和承载性能。采用芯棒辅助手铺技术制备复合材料管。管是用24层蚕丝纤维制成的,用环氧基浸湿。然后将管分别切成50mm, 80mm和120mm的不同长度。每个类别测试三个标本。通过测量最大峰值载荷(Pmax)、比吸收能量(SAE)和总吸收能量(TE)与管长的关系,对实验结果进行了分析。研究结果显示,结果会随着试管长度的变化而发生不可预测的变化。利用高分辨率相机对试验过程中获得的照片进行了破坏破碎分析,结果表明压缩载荷引起的微裂纹是主要的破坏来源。

Fair Trade and Sustainability in the British Textile Industry: An Evolution from Exploitation towards Global ‘Equality’ 英国纺织业的公平贸易与可持续发展:从剥削到全球“平等”的演变
Pub Date : 2017-12-07 DOI: 10.4172/2165-8064.1000324

Organisations are currently adjusting their value chains to take account of consumer demand for sustainable development. They are also responding to new understandings of sustainability in textiles and branding for consumers in a globalised world. This paper analyses and discusses the evolution of a global textile pipeline into the concept of global citizenship, in which individuals evaluate the international consequences of their local behaviour. Aiming to analyse the awareness and general understanding of consumers in regards to sustainability within the apparel industry a systemic multi-worldview field research was carried out between 2014 and 2016. To do this, three sets of semi-structured interviews were developed: one for the members of the BAFTS (British Association for Fair Trade Shops and Suppliers), one for the Marketing and Membership Coordinator of this body, and a third one to a three sustainable companies not associated to BAFTS (establishing a control group). Confronted with Sachs’ five sustainable dimensions framework the interview results were analysed, as well as future implications.
组织目前正在调整其价值链,以考虑到消费者对可持续发展的需求。它们也在回应全球化世界中消费者对纺织品和品牌可持续性的新理解。本文分析并讨论了全球纺织管道向全球公民概念的演变,其中个人评估其当地行为的国际后果。为了分析消费者对服装行业可持续发展的认识和一般理解,在2014年至2016年期间进行了系统的多世界观实地研究。为此,开发了三套半结构化访谈:一套针对英国公平贸易商店和供应商协会(BAFTS)的成员,一套针对该机构的营销和会员协调员,第三套针对三家与BAFTS无关的可持续发展公司(建立对照组)。面对萨克斯的五个可持续发展的维度框架,访谈结果进行了分析,以及未来的启示。

Alumina Production and the Textile Industry 氧化铝生产和纺织工业
Pub Date : 2017-12-07 DOI: 10.4172/2165-8064.1000327
F. Habashi
The Bayer process used today for the production of alumina was originally discovered in Saint Petereburg in Russia in the Tentelev Chemical Plant for supplying mordants to the textile industry. Bayer replaced the Le Chatelier process for preparing aluminum hydroxide invented in 1855 by the sintering process by his method for preparing aluminum hydroxide by seeding in 1888 then by leaching bauxite under pressure in 1892 to recover sodium hydroxide. The process was used unviserally for the treating of bauxite for supplying the growing aluminum industry by alumina.
今天用于生产氧化铝的拜耳工艺最初是在俄罗斯圣彼得堡的Tentelev化工厂发现的,该化工厂为纺织工业提供媒染剂。拜耳在1888年用播种法制备氢氧化铝,1892年用压力浸出铝土矿法回收氢氧化钠,用烧结法取代了1855年发明的勒夏特列制备氢氧化铝的方法。该工艺被广泛应用于铝土矿的处理,为日益增长的铝工业提供氧化铝。
