随着时代的进步,人们对鞋类卫生性能越来越重视。本文初步探讨了鞋类卫生性能方面的几个主要的物理值,起抛砖引玉的作用,以促进今后加强这方面的研究,确定检测方法和相应数据,以便在条件成熟时,将其纳入鞋类产品标准。 鞋类主要功能是保护人的健康,便于劳动、工作和休息,装饰和美化是鞋的第二功能,人们对鞋类功能的要求,取决于社会经济文化的发展程度。我国五、六十年代人们要求鞋类庄重高雅、结实耐用;七、八十年代要求鞋类花色翻新、功能专一,于是出现了婚礼鞋、跳舞鞋、散步鞋、休闲鞋、旅游鞋等;进入九十年代人们不仅要求功能专一,而且更要轻、软、舒适,卫生性能良 相似文献

ABSTRACT: Films based on whey protein isolate (WPI) were formed using compression molding. Compression molded films could be formed using 30% to 50% moisture content or glycerol content WPI at 104 °C to 160 °C for 2 min. Films made from water-WPI mixtures were brittle and insoluble and had water-vapor permeability values independent of starting water-WPI mixture moisture content, molding temperature, or molding pressure. Gly-WPI films produced at 104 °C were flexible and partially soluble. Gly-WPI films produced at 140 °C were also flexible but nearly insoluble. Glycerol content and molding temperature and pressure had little effect on water-vapor permeability values of Gly-WPI films over the range of conditions studied. 相似文献

为提高聚酯/聚酰胺6(PET/PA6)中空超细纤维合成革基布的透湿性、柔软性,将聚丙烯腈(PAN)纳米纤维与PET/PA6超细纤维混合,通过水刺固网的方法制备出PAN-PET/PA6微/纳米超细纤维合成革基布并进行碱处理,分析了PAN纳米纤维质量分数对革基布透气性、透湿性、吸湿性、柔软度及力学性能的影响。结果表明:当革基布面密度一定时,随着PAN纳米纤维质量分数的增加,革基布的透湿性、吸湿性、柔软度、撕裂性能提升,而透气性能和断裂强力有所下降;当PAN纳米纤维质量分数为20%时,革基布的透湿率提升了15.19%,吸水量提高了23.53%,柔软度增加了38.17%;经碱处理后,革基布的亲水性有了明显改善,透湿率提升了23.81%,吸水量提高了42.26%,柔软度提高了23.20%。 相似文献

The purpose of presented research is to find out the influence of air-jet yarn from the mixture of CO/PA (50/50) and CO/PES (67/33) fibres on functionality of woven fabric in the plain weave.The first part of the study is directed to the mechanical and physical properties of air-jet yarns (16.7 tex) from CO/PA and CO/PES fibres, while the second part of the study focuses on permeability properties of fabrics with air-jet yarns in the weft. The results show that air-jet yarn in the weft direction influences on the water vapor transmission and thermal conduction increase and air permeability decrease.Incorporation of air-jet yarn in the weft direction also improves breaking extension level.The results of presented research also show that the incorporation of air-jet yarn in the weft has statistical important influence on thermal conduction, water-vapor and air permeability changes. 相似文献

The structure-function relationship of composite films obtained from soybean-protein isolate (SPI) and cod gelatin was studied. Films with different ratios of SPI:gelatin (0, 25, 50, 75, 100% [w/w]) and plasticized by a mixture of glycerol and sorbitol were prepared by casting. Regardless of the soybean-protein concentration, the thickness and water-vapor permeability of the composite films diminished significantly as compared to pure-gelatin films. The formulation containing 25% SPI: 75% cod-skin gelatin had the maximum force at the breaking point, which was 1.8-fold and 2.8-fold greater than those of 100% gelatin and 100% SPI films, respectively. Moreover, this formulation offered high percent-deformation values lower than those of gelatin but higher than all other films containing SPI-, and the same relatively low water-vapor permeability as the 100% SPI film. While all the films exhibited high water solubility, a slight reduction in film solubility and soluble protein was observed with increasing SPI concentration. Differential-scanning calorimetry analyses revealed that gelatin was completely denatured in all films, while soy proteins largely maintained their native conformation. Analysis by fourier-transform–infrared spectroscopy revealed that the presence of 25% SPI produced gelatin conformational changes, self-aggregation of gelatin chains, and intermolecular associations via CO bonds between gelatin and SPI proteins. All films were translucent in appearance, but the yellowish color increased with increasing proportions of the soybean proteins. 相似文献

为了提高可食性膜的透明度和阻隔性,制备一种速溶的普鲁兰多糖-明胶可食性膜。将普鲁兰多糖添加到明胶膜中,普鲁兰多糖和明胶的添加质量比为2∶5(PG2)。在此配比下,普鲁兰多糖-明胶可食性膜的抗拉强度是明胶可食性膜的120%,氧气透过率是明胶可食性膜的1/13。可食性膜PG2中普鲁兰多糖和明胶分子间具有较强的氢键作用,并且此时可食性膜具有较好的相容性,因此使可食性膜PG2抗拉强度增强和氧气透过率降低。可食性膜PG2具有较低的氧气透过率(0.15 mL/(m2•d))、较高的抗拉强度(97.21 MPa)和溶水时间(29.5 s),而且具有不透油和低水蒸气透过率(109.08 g/(m2•d))的性质,因此,可食性膜PG2是适合应用于可食性内包装的材料。 相似文献
