Textiles play a pivotal role in people's daily lives. As consumers become increasingly environmentally conscious and health-conscious, they are not only demanding comfort, safety, and functionality in finished products but also beginning to place emphasis on the quality of products at every stage from raw materials to finished goods, as well as the control of supply chain origins. Textile manufacturers and exporters are facing unprecedented challenges.
Textile testing is the process of inspecting, measuring, and evaluating the performance and quality of textile materials (fibers, yarns, etc.) and textile products (fabrics, clothing, etc.). Different countries have varying requirements for textile testing and have established different laws and regulations to regulate this process.
Clothing testing projects include: clothing sizing, raw materials (fabric, lining, accessories, thread, buttons, etc.), warp and weft yarn direction technology, stripe and check alignment, seam requirements, color difference, surface defects, sewing requirements, dimensional tolerance limits for key areas of the finished product, physical and chemical performance requirements, colorfastness, pilling, sewing strength, formaldehyde content, and product labeling evaluation.
1.What are the different applications of various textiles?
Apparel textiles: These include various textile fabrics used for clothing production, as well as sewing threads, elastic bands, collar linings, lining materials, and knitted garments such as gloves and socks.
Decorative textiles: These can be divided into indoor items, bedding, and outdoor items. Bedding includes bedspreads, sheets, quilt covers, duvet covers, blankets, towel blankets, pillow inserts, quilt inserts, and pillowcases. Outdoor items include artificial turf, etc.
Industrial textiles: These have a wide range of applications, with numerous varieties available in knitwear wholesale. Common examples include tarpaulins, gun covers, filter cloths, screens, and road base cloths.
2.What are the common testing items for textiles?
Physical testing, chemical testing, dimensional testing, colorfastness testing, formaldehyde testing, component analysis, and toxicological testing, among others.
3.What are the testing items for textiles?
There are thousands of testing items for textiles. The specific testing items are determined based on the textile samples provided by the customer, combined with the final testing requirements, to confirm one or more testing contents and conduct targeted testing for the project.
Taking physical testing as an example, the scope of testing includes density, yarn count, grammage, yarn twist, yarn strength, fabric structure, fabric thickness, loop length, curl deformation, tensile strength, tear strength, seam slippage, seam strength, adhesive strength, single yarn strength, resistance to pilling, water permeability, abrasion resistance, and anti-static properties.
For chemical testing, the scope of testing includes pH content, formaldehyde content, lead content, azo dye testing, heavy metal content testing, absorbency, moisture content, odor, cotton's silk finish effect, heat pressing, dry heat, storage sublimation, acid spots, alkali spots, water spots, and phenol-formaldehyde yellowing.
Scope of testing:
| Ready-made garments | Outerwear, down jackets, pants, sweaters, T-shirts, skirts, cotton coats, etc. |
| Various fiber composition fabrics | Cotton, linen, wool, silk, polyester, viscose, spandex, nylon, CVC, etc. |
