The fabrics used to make parachutes and paragliders must have the several specific characteristics: the mass of fabric per unit of surface must be low while the other physical- mechanical characteristics (the axial breaking strength load, the relative and absolute elongation, the tear resistance of the fabric and the assemblies, air permeability) must be at a maximum. The paper deals with the analysis of qualitative aspects of several parachute fabrics that are used as a baseline in the development of a novel fabric. The results of experiments have materialized in statistical data, diagrams and graphs and their interpretation leads to the determination of the fabric variant that best meets the requirements of the destination. The destination is a patent pending inflatable wing design that utilizes a single skin construction and solid reinforcements in the sewing for shape stability. It is worth noting that the experimental results were compared with values indicated in specific international testing norms.
用于制造降落伞和滑翔伞的织物必须具有几个特定的特性:单位表面的织物质量必须低,而其他物理机械特性(轴向断裂强度载荷,相对和绝对伸长率,织物及其组件的抗撕裂性,透气性)必须达到最大值。本文对几种降落伞织物的定性分析,作为开发一种新型织物的基准。实验结果以统计数据、图表和图形的形式体现出来,通过对实验结果的解释,确定最符合目的地要求的织物变型。目标是一项正在申请专利的充气机翼设计,该设计利用单一皮肤结构和坚固的缝线加强形状稳定性。值得注意的是,实验结果与特定的国际测试规范所指示的值进行了比较。

Texturized yarns are often preferred especially in home textiles and sportswear. To improve polyester filament properties, mechanical, thermal, chemical and combinations of texturingprocesses are applied. With these processes, filament yarns take on a curved and voluminous structure and gain a permanent form. Properties of the texturized yarn can be varied as raw materials properties, machine type and process factors. This study covers the investigation of the effect of cross-sectional shape of fiber (round and trilobal) and texturing process temperature (150, 175 and 200 0C) on air permeability of false twist textured polyester single jersey knitted fabrics.Results showed that the highest air permeability value was obtained from knitted fabric with round fiber cross-sectional shape polyester filament textured at 150 0C. According to the statistical analysis, both the fiber cross-sectional shape and process temperature were found to have a significant effect on air permeability property.
特别是在家用纺织品和运动服中,经常首选有纹理的纱线。为了提高涤纶长丝的性能,应用了机械、热、化学和组合织构工艺。通过这些工艺,长丝纱线呈现出弯曲和体积的结构,并获得永久的形状。变形纱的性能随原料性能、机器类型和工艺因素而变化。本文研究了纤维截面形状(圆形和三叶形)和变形工艺温度(150℃、175℃和200℃)对涤丝假捻变形针织物透气性的影响。结果表明,在150℃下经织构的圆形截面型涤纶长丝针织物透气性最高。通过统计分析,发现纤维截面形状和工艺温度对透气性有显著影响。

Abstract:Poly (ԑ-caprolactone) (PCL) is a member of petrochemical raw material based biodegradable polyesters. Numerous studies have applied electrospinning, wet spinning and melt spinning techniques for processing fibers from PCL and its copolymers. The thermoplastic nature, low melting point and high extensibility of PCL makes it a good candidate for processing with melt-spinning method which is an economic and environment friendly fiber production process. Several studies have investigated the production of PCL fibers via melt-spinning; however, there is still significant room for improvement in process parameters and fiber properties. Therefore, in this study, we used different spin pack designs, extrusion and drawing parameters for the melt spinning of neat PCL filaments. Melt-spun solid and hollow multifilaments having smooth surfaces were successfully produced by using a lab-scale melt spinning device. Crystallinity of multifilaments remained unchanged in terms of production parameters. Tensile test results suggest that PCL filaments can be produced using various types of spin packs with decent mechanical properties by means of melt spinning. Hollow structure can extend the field of application of fibers in medical appicatios by taking the advabtage of its carrier properties.
摘要:聚(ԑ-己内酯)(PCL)是石油化工原料基可生物降解聚酯中的一员。大量的研究应用静电纺丝、湿法纺丝和熔融纺丝技术来加工PCL及其共聚物的纤维。PCL的热塑性、低熔点和高延伸性使其成为一种经济、环保的纤维生产工艺。一些研究研究了熔融纺丝法生产PCL纤维;然而,在工艺参数和纤维性能方面仍有很大的改进空间。因此,在本研究中,我们采用不同的纺丝包设计、挤出和拉伸参数对整齐的PCL长丝进行熔体纺丝。利用实验室规模的熔融纺丝装置,成功地生产出表面光滑的固体和空心多丝。在生产参数方面,多丝的结晶度保持不变。拉伸试验结果表明,采用熔融纺丝的方法,可以生产出力学性能良好的各种纺丝包。中空结构利用纤维的载体特性,扩大了纤维在医疗领域的应用范围。

Electromagnetic radiation of telecommunication is undesired in rooms for data privacy [1]. One way to shield EM radiation is by achieving textile fabrics with electrical conductive properties [2,3]. Buildtech technical textiles are used in constructions and as such they need fireproof properties, too. Magnetron plasma sputtering is a novel technique for rendering nanometer scale coatings on woven fabrics. It is an eco-friendly technique, which leaves the bulk properties of the fabric unaltered and modifies only the surface properties. Thus, textile EM shields out of magnetron plasma coated fabrics keep initial properties of textile materials, such as flexibility, light weight, 3D shape-ability, good mechanical resistance and receive as well novel functionalities.The ERA-NET Manunet TexEMFiRe project aims to research Buildtech technical fabrics with electromagnetic shielding and fireproof properties, made out of magnetron plasma coating. TexEMFire envisages an optimization of plasma coated fabrics based on fabric structure parameters (density) and plasma coating parameters (generator power) The project has duration of two years (Apr. 2018-Mar. 2020) and five partners: INFLPR, INCDTP, Majutex from Romania and UniUPO and TecnoLab from Italy.

为了保证数据的隐私,不希望在机房中出现电信电磁辐射[1]。屏蔽电磁辐射的一种方法是实现具有导电性能的纺织织物[2,3]。Buildtech技术纺织品用于建筑,因此它们也需要防火性能。磁控等离子溅射技术是一种在机织物上制备纳米级涂层的新技术。这是一种环保技术,它使织物的整体特性保持不变,只改变表面特性。因此,由磁控管等离子体涂层织物制成的纺织电磁屏蔽保持了纺织材料的初始特性,如柔韧性、重量轻、3D成形能力、良好的机械阻力以及新颖的功能。ERA-NET Manunet TexEMFiRe项目旨在研究由磁控管等离子涂层制成的具有电磁屏蔽和防火性能的Buildtech技术织物。TexEMFire设想基于织物结构参数(密度)和等离子涂层参数(发电机功率)对等离子涂层织物进行优化。该项目为期两年(2018年4月至2018年3月)。2020)和五个合作伙伴:INFLPR, INCDTP,罗马尼亚的Majutex和意大利的UniUPO和TecnoLab。项目网址:http://texemfire.inflpr.ro/。

The textile industry is one of the most important polluters of the environment. The linear economic system, which dominates the sector, puts pressure on resources, pollutes and degrades the natural environment and its ecosystems and creates significant negative societal impacts on a local scale, regional and global. Given the multitude of technologies, which are growing exponentially, the complexity of current economic processes and society and the need to respond to growing environmental risk challenges, it is necessary to operationalize the textile sector through convergent solutions: disruptive innovation, circular economy, education for sustainable development. The article outlines the benchmarks of the spatial operational scale for creativity, innovation in the context of the textile field, from fiber to textiles, in the succession of (un)conventional, processing processes, on traditional production chains, finalized by specific activities for clothing production, respectively on multidisciplinary production chains, completed by activities specific to obtaining textile systems.
纺织工业是最重要的环境污染者之一。主导该部门的线性经济体系对资源造成压力,污染和退化自然环境及其生态系统,并在地方、区域和全球范围内造成重大的负面社会影响。考虑到以指数方式增长的众多技术、当前经济进程和社会的复杂性以及应对日益增长的环境风险挑战的必要性,有必要通过融合解决方案:颠覆性创新、循环经济、可持续发展教育来实现纺织行业的运营。本文概述了纺织领域背景下的创造力、创新的空间操作尺度的基准,从纤维到纺织品,在继承(非)常规、加工过程中,在传统生产链上,通过服装生产的特定活动完成,分别在多学科生产链上,通过特定活动完成获得纺织系统。

Abstract:Conducting polymers have the potential to be used in many technological fields due to their unique optical and electrical properties In this study, 3,4-ethylenedioxythiophene has been dispersed in aqueous medium by PSS and electrochemically coated on textile material. In order to increase the conductivity of cotton-based textile material, 40 micron thick steel wires have been added duringweaving. Electrochemical characterization of the coated textile material has been carried out by the cyclic voltammetry technique. Furthermore, by applying different potentials to the textile material, the color change has been determined with the naked eye. Unlike the related literature, conductive polymer coated textile material obtained by electrochemical polymerization instead of chemical polymerization can be used in many wearable electronicsfields

The paper presents the results of research works on ecological materials that protect humans against the harmful effects of ultraviolet (UV) radiation, made of organic cotton, obtained through the application of selected natural dyes and a new reactive UV absorber with high molar absorption. These materials are intended for clothing, in particular for children and people with photosensitive skin.Instrumental evaluation of obtained colours and barrier properties of textile products for UV radiation were performed, expressed in the UPF (Ultraviolet Protection Factor) value, determined on the basis of measurements of UV transmittance by a textile product.Due to the application area of the new materials, the colour fastness to washing, perspiration, friction and artificial light. For selected newly developed organic cotton products containing in their structure a natural dye and a new UV organic absorber, specialized irritation tests according to OECD were carried out. In addition, the results of studies on antimicrobial properties are presented on the basis of the assessment of antibacterial activity against Gram (+) Staphylococcus aureus and Gram (-) Escherichiacoli.

Denim washing is not such an old thing that is not known to us. It is done to get proper aesthetic look of the fabric. Denim washing or somehow called as denim finishing has its own scope in the market or industrial scale as it enhances the functional activity as well as the make fabric aesthetically more appealing This research work focuses on the different washing techniques of denim fabric keeping the environment as major concern with enzyme (Lava Cell NHC, bio-polish (Lava Cell NBP, enzyme and stone, resin (PULCRA STABITEX ETR+dip and resin spray. For this purpose, the leg tubes of 22×22 inches of denim fabric are made and prescribed recipes are applied on the fabric in an automatic tumble TONELLO machine. After that different tests were performed to investigate change in dimensional, pilling resistance, tensile Strength, tear Strength, absorbency and change in shade variation after different washing. And surface morphology of fabric samples after washing was investigate by SEM analysis.
牛仔水洗并不是我们不知道的古老事物。这样做是为了获得织物的适当美学外观。牛仔布洗涤或某种程度上被称为牛仔布整理在市场或工业规模上有自己的范围,因为它增强了功能活性,并使织物更具美观性。本研究工作侧重于牛仔布的不同洗涤技术,主要关注酶(熔岩细胞NHC),生物抛光(熔岩细胞NBP),酶和石头,树脂(PULCRA STABITEX ETR+浸渍和树脂喷雾。为此,在自动滚筒式TONELLO机器上制作22×22英寸牛仔织物的腿管,并将规定的配方涂在织物上。在此基础上,进行了不同洗涤方式下的尺寸、抗起球性能、抗拉强度、抗撕裂强度、吸光性、色度变化等试验。并用扫描电镜对织物洗涤后的表面形貌进行了研究。
