What are the routine textile testing items?

What are the routine textile testing items? In this article, Zhejiang Dingyi New Materials Technology Co., Ltd. will briefly introduce the relevant content.

Physical Performance Testing

The physical properties of textile testing include density, yarn count, gram weight, yarn twist, yarn strength, fabric structure, fabric thickness, loop length, fabric coverage factor, fabric wrinkle or fabric shrinkage, curved and twisted deformation, tensile strength, tear strength, seam sliding, seam strength, bond strength, single yarn strength, yarn strength per unit line density, hook thread, crease return angle test, stiffness test, water repellency test, leakage resistance, elasticity and recovery, breathability, water permeability, water permeability, general garment burning, children's evening wear burning, swelling strength, abrasion resistance test, pilling resistance, water penetration, abrasion resistance, anti-static, etc.

Chemical Performance Testing

Chemical performance analysis: PH content, formaldehyde content, lead content, azo dye test, heavy metal content test, water absorption, water content, odor, cotton mercerization effect, hot press, dry heat, storage sublimation, acid spot, alkali spots, water spots, phenolic yellowing, etc.

Dimensional changes related to testing

Washing machine size stability, hand washes size stability, dry cleaning size stability, steam size stability.

Colorfastness

Colorfastness to soap washing (sample), color fastness to rubbing, color fastness to chlorine water, color fastness to non-chlorine bleaching, color fastness to dry cleaning, color fastness to actual washing (garment, fabric), color fastness to perspiration stains, color fastness to water, color fastness to light, color fastness to seawater, color fastness to saliva.

Component yarn testing

Cotton, linen, wool (sheep, rabbit), silk, polyester, viscose, spandex, nylon, velvet, fabric composition and content, yarn twist, etc.

Eco-Textile Control Project

Azo dyes, carcinogenic dyes, allergenic dyes, extractable heavy metals, pentachlorophenol, organochlorobenzene and chlorotoluene, free formaldehyde, organotin compounds, phthalate plasticizers, hexavalent chromium, nickel release, total lead, total cadmium, pH, color fastness, etc. are prohibited.
