草木染.亦称植物染.采用天然植物、中药材、花卉、蔬菜、茶叶制成染料,为织物染色。蓝染、扎染、蜡染、蓝印花布等均属此类。草木染取法自然.无污染.染出的织物色泽纯净柔和.散发草木清香。初经水洗,虽略有褪色.但正如岁月漂洗后的颜色。有一种宁静的、生活的味道。  相似文献

1 前言 色牢度是印染纺织品的重要考核指标,而纺织品使用不同种类的染料其色牢度的考核指标不尽相同,因所用染料种类的不同,色牢度考核指标差异可达一级半。比如GB/T411—1993(棉印染布》标准规定,染色棉布耐洗牢度(白布沾色)还原染料4-5级,而硫化、纳夫妥、活性染料则为3级。这是因为各种染料的分子结构、化学性质等的不同,对不同的纺织品的结合方式、结合力也不相同,有的染料是与纺织纤维分子发生化学反应而以化学键的方式结合在纺织物上,而有的染料是以物理反应的方式固着在纺织物上。  相似文献

Productivity growth may be affected particularly for developing countries by international linkages or technology transfer. We evaluate relationships between productivity and FDI, exports, imports and licensing for Turkish manufacturing plants in the apparel, textiles, and motor vehicles industries. We assess performance premia associated with these international technology transfer channels that control for plant size and location. We then use a structural model to allow for plant-specific input composition and interactions, estimated alternatively by quantile regression and semi-parametric techniques to recognize plant heterogeneity and to accommodate simultaneity and selection issues. Overall, we find that productivity is most closely related to foreign ownership, especially for larger plants and in combination with other forms of technology transfer, followed by exporting and then licensing.  相似文献

我国纺织品出口对经济增长贡献的实证研究   总被引:1,自引:0,他引:1  
出口贸易是影响经济增长的重要因素。本文采用1980-2004年的数据,描述了我国纺织品出口的特点,并借助协整模型实证研究了纺织品出口对经济增长的影响,指出二者之间存在长期的动态关系。通过定量分析,发现纺织品出口对经济增长的直接拉动度和贡献率都较低,这是因为我国纺织服装行业一方面受宏观环境影响,另一方面自身竞争优势不足。本文经过研究,形成了对我国纺织品出口与经济增长之间关系直观而清晰的认识,并为无配额时代我国纺织业发展的后续研究提供了参考。  相似文献

The purpose of this study was to determine concentrations of detergent residues in textiles washed with three types of detergents. One detergent contained phosphate. In the other two (concentrated or ecological detergents) phosphate had been replaced by zeolite, which contains silicates. The textiles were washed using two programmes for coloured materials (at 60°C). The programmes differed with regard to volume of rinse water and number of rinsings. Detergent residues in textiles were determined chemically. Zeolite particles were determined electron microscopically. The results showed that most of the detergent residues remaining in textile strips were anionic tensides. They increased in proportion to the quantity of detergent used for washing. The least residues were left by concentrated detergents. Anionic tensides are suspected of causing skin irritation, probably allergy in atopic persons. Zeolite particles may irritate skin mechanically or cause through irritation respiratory distress. Washing programmes using less rinse water than other programmes increased detergent residues by 30%. It is concluded that there is a positive linear relationship between concentration of detergent and residues in textiles, and a negative linear relationship between water volume and residues in textiles after laundering. This could be of considerable importance from a health point of view and should be evaluated before any detergent is marketed. A methodology combining different standardized methods for analysing detergent residues in textiles was developed in this study.  相似文献

A survey of teachers, parents and students was conducted to determine appropriate content for a semester course in clothing and textiles. A review of literature including research, curriculum guides, projections of future trends in clothing and textiles and knowledge needs of consumers served as the basis for developing the instrument. The initial list of topics identified was reduced to 13 major topics and 66 specific items by a panel of eight experts. The instrument was used to survey 1200 teachers, parents and students. A total of 327 surveys were returned. Respondents were varied on most demographic characteristics identified. Results were analysed to determine the significance of differences between the responses of the three groups. Respondents indicated that no more than Homemaking I should be required as a prerequisite for a clothing and textiles semester course and that simple clothing construction skills should be included. The overall rankings of the 13 major topics was: wardrobe planning, clothing selection, clothing construction, buying clothing, clothing care, clothing alterations, sewing tools and equipment, effects of clothing on individuals, design in clothing, textiles, family clothing, influences on fashion, clothing and textiles careers. Significant differences between groups existed for mean importance scores of 36 of the 66 specific topics. Teachers' mean importance scores differed from those of parents and/or students on 33 topics. Recommendations for content of a clothing and textiles semester course were based on the findings.  相似文献
