Learn The Truth About Textile Testing Methods of Textile Testing

Textile quality testing is primarily a chemical test. For the analysis of the chemical composition of textile and apparel products there are the following testing methods.

 

1. Conventional testing: fibers, yarns, chemical fiber filaments, textile (knitted) fabrics, clothing and down products and USTER yarns and other types of chemical composition analysis.

 

2. Special testing: fire retardant, wear-resistant, moisture permeable, breathable, water permeable, anti-static and other special performance testing of textiles.

 

3. Ecological textile testing: pH value of textiles, formaldehyde content, prohibited azo dyes, extractable heavy metal content, pesticide residues, dyeing fastness, odor detection.

 

4. Dyes, auxiliaries testing: pH value of dyes and auxiliaries, formaldehyde content, dyeing fastness, banned azo dyes, heavy metal content, allergic dyes, dyes identification, solid content, impurity analysis, etc.

 

5. Textile materials testing: textile materials refer to fibers and fiber products, specifically fibers, yarns, fabrics and their compounds.

6. Fiber: is the basic unit of textile materials. The source, composition, preparation, form and performance of fibers are extremely complex and directly affect the nature of fiber aggregates, as well as the practical and commercial value of fibers. From the chemical composition analysis we understand fiber should start from the name of fiber, classification, naming and basic characteristics of fiber, the current situation and development, to form an objective, clear cognitive judgment and categorization of the concept and rules of naming.

 

7. Yarn: Yarn processed with textile fibers is diverse, because there are different types of fibers and different forms of yarn processing, resulting in different yarn structures; different physical properties and use characteristics caused by different yarn structures. Depending on their use, yarns can be used as semi-finished or finished products, i.e. yarns for processing (blended yarns, variegated blended yarns, combined or compound yarns) and yarns for final use (pure spun yarns, blended yarns, companion spun yarns).

 

8. Other classification: Mainly the customary name for yarn in production and processing.

 

Testing items.

 

1. Fiber composition and other analysis testing (according to standard 100, GB 18401 full set, ASTM, AATCC, ISO, EN, etc. for testing of textiles).

 

2. Garment ingredients testing (zippers, buttons, etc.), down products testing, color fastness testing.

 

3. Tissue structure analysis, leather products testing, dimensional stability and related testing, cotton filling testing, strength testing, performance testing, combustion testing.

 

4. Antimicrobial material testing: whether to play a role in resistance to E. coli, Staphylococcus, Klebsiella pneumoniae, Pseudomonas aeruginosa, etc.

 

5. Dimethyl fumarate (DMF) testing: widely used in footwear products as a cheap and low-toxic mildew inhibitor, which can cause skin allergy, rash or burns. The EU from May 1, 2009, banned products containing DMF on the market.

 

6. Azo (AZO) detection: Azo will emit carcinogenic gas, resulting in serious health effects on customers.

 

Chemical testing is very important in textiles, in order to product safety, the producer, buyer or third party can use third-party testing organizations, the quality of goods, specifications, weight, quantity, packaging, safety and health inspection, etc., to reach a smooth transaction.
