What are the items of fabric testing?

The purpose of fabric inspection is to evaluate the quality of fabric, analyze and study the composition, structure and performance of fabric from the use of fabric, so as to determine the value of fabric and identify whether it meets the prescribed standards. So what are the items of fabric testing?

1, physical indicators: physical indicators include the appearance quality inspection of fabrics, including specifications, sizes, defects, color difference, weft skew, etc. , as well as strength, gram weight, color difference, color fastness, flame retardancy, appearance after washing, shrinkage after washing, pilling, etc.

2. Chemical indicators: Chemical indicators mainly include formaldehyde content, PH value, presence or absence of odor, presence or absence of banned dyes (azo dyes that can crack aromatic amines), presence or absence of heavy metals, presence or absence of fluorescence, presence or absence of banned surfactants such as APEONPEOPFOS, etc.

3. Wearability: The fabric properties include the handle, smoothness, bulkiness and softness of the fabric, which need to be tested by professional fabric testing institutions.

That's all about fabric testing.
