Textile Testing | How To Make Garment Quality Visible

Recently, Shanghai’s regulatory authorities have focused on spot checks on skirts, luxury clothing and silk clothing sold in Shanghai, involving a total of 166 brands and 255 batches of products. After testing, there were 56 batches of unqualified products with a failure rate of 22%. One of the women’s dresses also detected carcinogens banned by the country. The test results show that there are 56 batches of substandard products, including many well-known clothing brands such as Coach, Boy London, and Neissy.

As the test report shows, the unqualified test projects are pilling resistance, dry rub fastness, wet rub fastness, ornament pull strength, pH value, product instruction and etc.

Pills is fiber balls which is caused by wear abrasion when groups of short or broken fibre on the surface of the fabric become tangled together. One of the most common pilling tests for fabric is Martindale pilling test. This method would rub the sample in all direction under certain load. ICI pilling test is also a popular pilling test method. Sample would be fixed on test tube surface and put into test chamber, then run for certain cycles.

Ornament pull strength test is essential especially for children’s product. Manufacturer must ensure the ornament would not be pulled off easily as it may be swallowed by children accidentally. EN 71 has clear requirement for that.

Fiber composition analysis has strict requirements for clothing and home textiles. The characteristics of the product are mainly reflected in the type of fiber and the proportion of fiber content.

The surface of human skin is weakly alkaline. If the pH value of the textiles used or worn exceeds the standard, it is easy to break the balance of human skin and bring health risks. In the garment production process, various dyes, auxiliaries and other chemical agents need to be added in the production process such as printing and dyeing. During the finishing process, insufficient rinsing, etc., cause the pH value to deviate from the standard value, resulting in improper acid and alkali in the garment. There are many reasons why the pH value of clothing exceeds the standard. However, after the fabric is printed and dyed, it is not fully washed and dried before leaving the factory. At the same time, no neutralization measures have been taken. This is the main reason for the unqualified pH value. Inferior fabrics will also be identified. The pH value exceeds the standard, so buy new clothes, especially children, infants and young children’s clothing, do not wear them directly, rinse them with water and then wear them.
