The disposal of many rubbish materials affects the environment because they persist for a long period of time on the earth without degrading. Among the rubbish materials, medical gloves are the one that are disposed to the environment daily from different health centers all over the world. This leads to great environmental problems on soil, ground and surface water, plants, animals and human beings. Emission of bad odour and luck of storing place are the other problems of the disposed medical gloves into the landfills. The goal of this study is to recycle these disposable gloves and manufacture a full composite end product used for partition of shelves or different rooms. In this investigation an attempt has been made to determine the recyclability of medical gloves. The study was done by using molten gloves reinforced with jute fabric, which impart better strength for the composite end product. Thermal sterilization method at a temperature of 100°C was used for disinfecting the medical gloves. After sterilization the gloves wear melted using metal pot and composite was manufactured using hand layup technique. The manufactured composites were tested to study the mechanical properties of the composite, tensile strength, flexural strength, impact strength and hardness. The mean tensile strength of the composite (563.009, 664.7577 MPa), the mean compression of composite (1.3, 2.47 MPa) and the mean bending strength (0.99, 1.35 MPa) were recorded for two and three jute fabric layer composite product respectively. The results indicated that the recycling of medical gloves under the use of composite manufacturing gives very strong end product functional for the partition purpose.
许多垃圾的处理影响环境,因为它们在地球上持续很长一段时间而不降解。在这些垃圾中,医用手套是每天从世界各地不同的医疗中心排放到环境中的一种。这导致了土壤、地下水和地表水、植物、动物和人类的巨大环境问题。难闻的气味和存放地点的运气是处理后的医用手套进入垃圾填埋场的其他问题。本研究的目的是回收这些一次性手套,并制造一个完全复合的最终产品,用于货架或不同房间的隔断。在这项调查中,试图确定医用手套的可回收性。该研究是通过用黄麻织物增强熔融手套来完成的,这为复合最终产品提供了更好的强度。医用手套采用100℃热灭菌法消毒。消毒后的手套用金属锅熔化,用手工叠层法制备复合材料。对制备的复合材料进行了力学性能测试,研究了复合材料的拉伸强度、弯曲强度、冲击强度和硬度。两层和三层复合材料的平均拉伸强度分别为563.009、664.7577 MPa,平均压缩强度分别为1.3、2.47 MPa,平均抗弯强度分别为0.99、1.35 MPa。结果表明,在复合材料制造的条件下,医用手套的回收利用具有很强的终端产品隔断功能。

The pore size is one of the vital morphological characteristics of barrier fabrics as it decisively affects their permeability and retention properties. Apart from fabric construction and material aspects, the pore size also depends on applied mechanical loads, which occur during typical usage life cycles. Among others, barrier fabrics such as surgical gowns are exposed to loads during their use. These loads have a significant effect on the fabric morphology which influences the permeability properties as well. In this study, a newly developed in situ pore size measurement method was used to measure the changes in pore size that occur in high density barrier woven fabrics under biaxial loadings and after cyclic loading. It was observed that, under tension, pore size distributions changed and mean flow pore sizes increased. Results revealed that the developed in situ measurement method has a great potential for the determination of pore size changes in barrier textiles under biaxial loading.
孔隙大小是阻隔织物的重要形态特征之一,它决定着阻隔织物的透气性和截留性。除了织物结构和材料方面,孔径也取决于施加的机械载荷,这发生在典型的使用寿命周期。其中,屏障织物,如手术服,在使用过程中暴露在负荷下。这些载荷对织物的形态有显著的影响,从而影响织物的透气性。在本研究中,采用一种新开发的原位孔径测量方法来测量高密度阻隔机织物在双轴加载和循环加载后的孔径变化。结果表明,在拉伸作用下,孔隙尺寸分布发生变化,平均流动孔径增大。结果表明,所建立的原位测量方法在测定双向载荷作用下屏障织物的孔隙大小变化方面具有很大的潜力。

Conducting polymer coated in textiles possess a wide range of electrical properties. The surface resistivity is influenced by concentrations of the reactants, thickness of the coating, nature of the substrate surface, extent of penetration of the polymer into the textile structure and the strength of the binding of the coating to the textile surface. Low resistivity in fabric results from highly doped thicker coatings that penetrate well into the textile structure thus enabling good electrical contact between fibers. In this study, we had chosen copper as conductor polymer for coating. The electrical conductivity is influenced by the thickness of coating paste, the nature of the substrate surface. The thickness of the paste and the concentration of the copper were studied in this paper. Furthermore, the electrical surface resistance decreased from 68 MΩ to 8 MΩ with decreasing in coating thickness. However, the thickness of coated fabric is very important factor to determine conductivity and application of textile. In addition, we had noticed that the airflow is affected by the coating thickness which the penetration of the airflow differs from the lower thickness to the higher one. This study confirm that we can use coating woven fabric to develop a textile substrate responding to characteristics such as electrical resistance, drapability, air permeability and tensile strength, which are particularly important to be used as a support for flexible photovoltaic cells in clothes.
涂覆在纺织品上的导电聚合物具有广泛的电性能。表面电阻率受反应物浓度、涂层厚度、基材表面性质、聚合物对纺织品结构的渗透程度以及涂层与纺织品表面的结合强度的影响。织物的低电阻率源于高度掺杂的较厚涂层,这些涂层可以很好地渗透到纺织结构中,从而使纤维之间具有良好的电接触。在本研究中,我们选择了铜作为导体聚合物进行涂层。电导率受涂膏厚度、基材表面性质等因素的影响。对膏体的厚度和铜的浓度进行了研究。随着涂层厚度的减小,表面电阻从68 MΩ降至8 MΩ。然而,涂层织物的厚度是决定织物导电性和应用的重要因素。此外,我们还注意到气流受涂层厚度的影响,涂层厚度越低,气流的穿透力越大。这项研究证实,我们可以使用涂层机织织物来开发一种响应电阻、悬垂性、透气性和拉伸强度等特性的纺织基材,这些特性对于用作衣服中柔性光伏电池的支撑尤为重要。

This paper presents a comparative study of different 3D fabrics designed and produced to be used as mattress and seat overlays for bedridden or people with reduced mobility. Two 3D patterns were developed using a doubleweaving process. The effect of pick density and filling weft linear density on the thermal properties, air and water vapour permeability and wicking ability of the resulting 3D fabrics was evaluated and compared. The obtained results demonstrated that the fabrics produced with the pattern with less number of intersections and lengthier floats (striped channel structure), less pick density and finer filling weft yarns, depicted the highest air and moisture transfer properties, which makes them a better solution for a cushioning interface material.

Spirality in Knitted Fabric 针织物的螺旋度
Pub Date : 2018-04-10 DOI: 10.4172/2165-8064.1000350
H. Jamshaid
Knit wear industry is growing at a faster rate across the globe and technological innovations contribute a lot in the success of industry. Knitted cotton fabric is considered ideal for next-toskin wear. Knit wear fabrics are popular because of their excellent properties of comfort, softness, sweat absorption, durability and softness. The dimensional stability is a serious problem with reference to quality. Quality of the fabric is of prime concern in placement of new ties between buyers and manufacturers. Consumers, now days, are becoming increasingly concerned and aware of fabric quality and accept higher quality standards than ever before. Pakistan’s knit wear industry is lagging behind the world knitting industry due to its less command and control over quality awareness and implementation of quality standards. Various defects in knitted fabrics affect the quality but spirality is the most common fault that affects the single jersey knit wear fabric. Single jersey fabric is mostly used for T-Shirts, sports wears and under garments, so position of seam is very important in the exact shape of the product, more is spirality, more de shaped is the end product.
针织服装行业在全球范围内以更快的速度增长,技术创新对行业的成功做出了很大贡献。针织棉织物被认为是贴身穿着的理想选择。针织面料因其舒适、柔软、吸汗、耐久、柔软等优良性能而广受欢迎。尺寸稳定性是关系到质量的一个严重问题。织物的质量是在买家和制造商之间建立新联系的首要考虑因素。如今,消费者越来越关注和意识到织物的质量,并接受比以往更高的质量标准。巴基斯坦针织服装行业由于对质量意识和质量标准的执行缺乏指挥和控制,落后于世界针织行业。针织物的各种缺陷都会影响织物的质量,而螺旋度是影响针织单件织物质量的最常见缺陷。单件针织面料多用于t恤、运动服和内衣,所以接缝的位置对产品的确切形状非常重要,越呈螺旋形,越呈异形就是最终产品。

Electrically conducting and additionally ferromagnetic materials in mix with fibers and textiles are ended up being compelling in shielding against electromagnetic radiation. Fine wires of copper, steel or silver mixed with textile fibers are the broadly examined materials for electromagnetic shielding. Composite yarns containing metallic wires and textile fibers delivered by friction spinning, core spinning or twisting are changed over into fabrics for EMI shielding. Mixing textile fibers with metallic wires enhances the textile attributes and process execution. One thinks that it’s difficult to weave a metallic wire in typical weaving machine rather a composite yarn, correspondingly to knit moreover. Be that as it may, metal coated fiber/yarns are monetarily accessible with great electrical conductivity and textile attributes.

In this study-the ecological parameters of the effluents obtained from scouring and dyeing with reactive dyes of Remazol brand for conventional cotton single jersey knitted fabric as well as bio-scouring and dyeing with low impact reactive dyes of Avitera brand for organic cotton single jersey fabric have been investigated. The ecological parameters include chemical oxygen demand (COD), biological oxygen demand (BOD), total dissolved solids (TDS), Total Suspended Solid (TSS), dissolved oxygen (DO), EC or conductivity, alkalinity and pH. Also some selected physical properties have been investigated for both dyed fabrics such as bursting strength, fabric drapability, color fastness to wash, color fastness to rubbing and color fastness to perspiration. The results of ecological test show greater ecological advances for using organic cotton, bio scouring and low impact reactive dyes than the conventional method and raw materials. In addition, the bleaching process has eliminated by dyeing with deep shade that results less toxic chemicals in effluent. The physical properties also showed better results of using eco-friendly fabric and processes.
本研究考察了用Remazol牌活性染料对普通棉针织单衫织物进行练染所得出水的生态参数,以及用Avitera牌低冲击活性染料对有机棉针织单衫织物进行生物练染所得出水的生态参数。生态参数包括化学需氧量(COD)、生物需氧量(BOD)、总溶解固形物(TDS)、总悬浮固形物(TSS)、溶解氧(DO)、电导率(EC)或电导率(电导率)、碱度和ph。此外,还研究了两种染色织物的一些物理性能,如破裂强度、织物悬垂性、洗涤色牢度、摩擦色牢度和耐汗色牢度。生态试验结果表明,使用有机棉、生物精练和低冲击活性染料比传统方法和原料具有更大的生态优越性。此外,漂白过程已被用深阴影染色消除,从而减少了废水中的有毒化学物质。采用环保面料和工艺后,织物的物理性能也得到了改善。

To minimize water and energy consumption, it has become necessary to combine several textile processing stages in order to reduce the number of operations, process time and cost. In this project work an attempt was made to combine the pre-treatment process with optimal quantities of chemicals in single bath by varying different pH with the help of different buffers and comparison was made with conventional process. It has found that buffered system at pH 11 for 60 min shows the best result in respect to wicking test, drop test, immersion test, weight loss%, whiteness index, yellowness index. Then all the pre-treated samples were dyed with reactive dyes by varying the depth of shade. After dyeing it has been found that buffered system at pH 11 for 60 min can be selected for any depth of shades and buffered system at pH 11 for 45 min is suitable for dark shade. This kind of a one-bath process is shorter, consuming less energy and hence being less expensive. The combined processes also lead to substantial saving in water energy and time along with chemicals.
为了最大限度地减少水和能源的消耗,有必要将几个纺织加工阶段结合起来,以减少操作次数、加工时间和成本。在本项目工作中,尝试通过改变不同的pH值,在不同的缓冲液的帮助下,将预处理工艺与单浴中化学物质的最佳用量结合起来,并与常规工艺进行了比较。结果表明,在pH值为11的条件下,缓冲液的吸湿、跌落、浸没、失重率、白度、黄度等指标均达到最佳。然后用活性染料对所有预处理后的样品进行染色,改变色度的深度。染色后发现,pH值为11 60分钟的缓冲体系可用于任何深度的阴影,pH值为11 45分钟的缓冲体系适用于深色阴影。这种一浴过程更短,消耗更少的能量,因此更便宜。结合的过程也导致大量节约水,能源和时间以及化学品。

In this study an attempt has been focus on developing antibacterial finish using natural herbs. The cotton fabric samples were mordanted using natural mordants pomegranate and myrobalon. The mordanted fabrics were dyed with a natural dye Acacia catechu and the fabrics were finished with three herbal extracts of Tridax procumbens, Plectranthus amboinicus and Mentha piperita by using dip method and pad dry cure method. The Antibacterial finishes of the finished fabrics was assessed against Gram positive and Gram negative bacteria and concluded that the pomegranate mordanted fabric finished with Tridax procumbens herb using pad dry cure method gives the excellent result due to herbal imparted in fabric helps to protect the human beings free from skin infections, fungal growth and bad odour.
本研究尝试以天然草药为原料开发抗菌整理剂。用天然媒染剂石榴和米罗巴隆对棉织物样品进行了媒染剂染色。以天然染料儿茶相思为染色剂,采用浸渍法和垫干固化法分别用三种草本植物提取物对毛毡织物进行染色。对织物的抗菌整理液进行了革兰氏阳性菌和革兰氏阴性菌的抑菌试验,结果表明,采用湿法干燥法整理的石榴浸染织物效果良好,因为织物中含有的草药有助于保护人体免受皮肤感染、真菌生长和难闻的气味。
