我国帘子布现状,发展态势与对策

一、帘子布发展历程简顾自 1888年英国人邓录普发明充气轮胎以来 ,110余年的历史就是帘子布行业从无到有、蓬勃发展的历史。充气轮胎刚发明的数年内 ,人们用亚麻平纹帆布作胎体增强材料 ,后因亚麻价格较高转而采用棉帆布。轮胎在使用时骨架材料受到拉伸力、压缩力的作用导致帆布受周期性的辗压 ,经、纬线在结点处互相磨损造成帆布强度的大幅度下降。为解决此问题 ,1893年 ,J.F.Palmer将经纬线密度相同的结构改为纬线密度 (6～ 12根 /10 cm)大大低于经线的结构。这种结构的织物就是直到今天仍在使用的帘子布。进入 2 0世纪后的一百年内 ,虽…

Radiationresistance and thermal stability of nylon 6, acrylonitrile copolymer and polyester fabrics

The thermal stability and radiation resistance of three polymers Nylon 6, acrylonitrile copolymer and polyester were investigated. The polymer samples were irradiated by low rate fission neutrons from a ²⁵²Cf source. The polyester showed a higher heat and radiation resistance than the two other polymers. It has to be recommended herein that polyester is the most suitable fiber for the manufacture of products in which heat buildup is produced during application, or products where radiation and heat resistance are required.     

Chemical modification of nylon 6 and polyester fabrics by ozone‐gas treatment

In a previous article, we reported on the ozone‐gas treatment of wool and silk fabrics in relation to the gas‐phase processing of textile fabrics. The treatment incorporated an oxygen element into the fiber surface and contributed to an increase in water penetration into the fabric. In this study, nylon 6 and polyester fabrics were treated with ozone gas in the same way as that of the wool and silk fabrics. The treatment incorporated much more oxygen into the fiber surface in the form of ? COH and ? COOH, as shown by electron spectroscopy for chemical analysis. Water penetration increased considerably with treatment, and the apparent dyeing rate and equilibrium dye uptake were also improved, especially for the polyester fabric, despite an increase in the crystallinity. Therefore, it seemed that the treatment brought about a change not only in the fiber surface but also in the internal structure of the fibers (the crystalline and amorphous regions) with regard to the dyeing behavior. Further, the mechanical characteristics of the ozone‐gas‐treated polyester and nylon 6 fabrics were measured with a Kawabata evaluation system apparatus. The shearing modulus and hysteresis widths increased with treatment, especially for the polyester fabric. Therefore, it was clear that the treatment caused a change in the fabric hand to crisp. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 100: 1344–1348, 2006

我国合成橡胶产业现状及发展

橡胶是橡胶工业中最基础的原料。据世界橡胶研究组织(IRSG)统计,2003年全世界橡胶消耗量为1920万吨,其中,合成橡胶(SR)1112万吨,占59%;天然橡胶(NR)788万吨,占41%。中国大陆橡胶消费量345万吨,占世界消费总量的18.2%;其中,消费NR145.5万吨,SR199.5万吨,分别占世界消费总量的18.5%和17.9%。随着国内以轮胎工业为代表的橡胶工业的发展,中国在世界橡胶消费市场中所占的份额将进一步提升。改革开放后,特别是1998年以来,中国橡胶工业发展对橡胶原料的消费量迅速增长,全国橡胶表观消费量从1998年的197万吨上升到2004年的415万吨,年均增长率高…     

Airbag fabric material modeling of nylon and polyester fabrics using a very simple neural network architecture

The material properties of engineering fabrics that are used to manufacture airbags can not be modeled easily by the available nonlinear elastic–plastic shell elements. A nonlinear membrane element that incorporates an elaborate tissue material model has been widely used by the auto industry for the airbag simulation studies. This model is highly computation intensive and does not differentiate between the various physical properties of the fabrics like fiber denier, the polymer fiber, and weave pattern. This paper introduces a new modeling technique that uses artificial neural networks. Experimental permeability data for fabrics under biaxial strain conditions were obtained through a blister-inflation technique and were used to train the proposed network architecture. In this training environment, various properties of the fabric can be incorporated and the network can be trained to generalize relative to the environment. Once trained, the cause–effect pattern is assimilated by the network with approprate weights to produce a desired output. Fabrics tested in this study included nylon 66 fabrics with three different fabric deniers: 420, 630, & 840 and two types of weave, and two 650-denier polyster fabrics having different calendering effects. The predictions obtained from this neural network model agreed very well with the experimental data. This indicates that neural nets can be considered as a serious design tool use in determining permeability and biaxial stress–strain relationships for textile fabrics used in airbags. © 1996 John Wiley & Sons, Inc.

Detection of hydroxyl radicals in photoirradiated wool, cotton, nylon and polyester fabrics using a fluorescent probe

Generation of hydroxyl radicals in the presence of buffered terephthalate solution produces flourescent 2-hydroxyterephthalate. Wool, nylon, cotton and polyester all generate hydroxyl radicals when irradiated with UVA light, and to a lesser extent with blue light, in terephthalate solution. Trace metal ions (particularly iron and copper) contribute to hydroxyl radical generation in wool and cotton. UVA irradation of wool in deuterated solution does not affect the concentration of hydroxyl radicals or the amount of yellowing observed relative to undeuterated solution. This suggests that 1O2 is not involved in the wet photoyellowing of wool. Although the photoinitiation stages are clearly different, it is likely that similar free radical processes are responsible for both hydroxyl radical production and wet photoyellowing in all four fibre types. This straight forward fluorescence technique has potential to correlate the free radical photodegeneration of fibres in the presence of various additives designed to improve performance.
