新疆地区纺织品pH值检测及其优化质量方法
|
摘要
针对在纺织品检测中,GB 18401—2003《国家纺织产品基本安全技术规范》的修订对新疆地区床上用品及校服质量产生的影响,以及该类直接接触皮肤的纺织品pH值容易超标等问题,通过调查取样检测,了解被检纺织品pH值的合格率,并对样品进行准确分类及结果分析,依据分类提出更加确切的结果判定,为增加产品安全性提供调查实践依据。对直接接触皮肤类纺织品,通过不同的水洗实验探讨减弱碱性的方法。结果表明:对GB 18401—2003趋于严格的修订使得检测结果更加全面可靠,对纺织品质量改善有促进作用。直接接触皮肤类纺织品pH值超标,可以通过采用0.15～0.30 g/L柠檬酸溶液清洗的方法,有效降低pH值,使织物接近中性。
In order to study the modification of the standard GB 18401-2003 "Basic Safety Technical Specification for National Textile Products" on quality of bedding and school uniforms in Xinjiang, and to solve the problem of pH value out of limits. Through investigation and sample test, the percentage of pass for pH value was tested. Through accurate classification, detection results and corresponding analysis, the accurate results were put forward, which is contributed to the product safety. For the textiles that direct contact with the skin, the method of reducing alkalinity was explored through different washing experiments. The results show that the strictly requirements of the GB 18401-2003 "Basic Safety Technical Specification for National Textile Products" can make the test results more comprehensive and reliable, and can promote the quality improvement of textiles. For these textiles, such as business used bedding and school uniforms, the problem of pH value beyond the limits can be solved by cleaned with in citric acid solution between 0.15 g/L and 0.30 g/L, in this way pH value can be effectively reduced to close to neutral.
