Key Indicators of Cashmere Garment Quality
- Fibre content. According to textile industry standards, if the product or part of the product is produced from some material, we use 100%, pure or all to represent fibre content and the tolerance is zero. Because of morphological variation, there is possibility that cashmere looks like wool. The product whose cashmere content is more than 95% or suspected wool lower than 5% can be called as “100% cashmere” or “pure cashmere”. In spot check of cashmere product, there are occasions when products are labled as 100% cashmere products whose cashmere content fails to meet standards.
- Dichloromethane soluble substance. Dichloromethane soluble substance is a kind of oil that comes from lubricating oil. According to product standards of cashmere knitwear, the dichloromethane soluble substance in 1st grade cashmere garment must be or lower than 1.7% .Because cashmere knitwear is priced by weight and if the oil content exceeds the standard, cashmere knitwear must be heavier than its actual weight, which would consumers’ benefits. In spot check of cashmere product, there are certain percent of products tested as non-conforming products due to excessive amount of dichloromethane soluble substance.
- Ph value. Ph value is used to represented the acidity or basicity of solution. The skin surface of human body is low-acid to prevent the bacterium invasion. Therefore, cashmere products with ph value between low acid and neutral are good for human body. According to national mandatory standards, clothes that touch skin directly should have ph value not beyond 7.5. Products with excessive ph value would damage the weak- acid environment of skin and lead to priritus and invasion of other bacteria even inflammation. In spot check of cashmer products, there are products that are tested as unqualified because of excessive ph value.
