What are the routine testing items for textiles

I. Physical property test

Textile physical properties test are density, yarn count, gram weight, yarn twist, yarn strength, fabric structure, fabric thickness, coil length, fabric coverage factor, fabric shrinkage or weave shrinkage, curved and twisted deformation, tensile strength, tear strength, seam slip, seam strength, bond strength, single yarn strength, yarn strength per unit of linear density, anti-hook wire, crease recovery angle test, stiffness test, water repellency test, water resistance test, leakage resistance, elasticity and recovery strength, breathability, water vapor permeability, general garment combustion, children's evening wear combustion, swelling strength, abrasion resistance test, water resistance test, water vapor permeability test. Leakage resistance, elasticity and recovery force, air permeability, water vapor permeability, general garment combustibility, children's evening wear combustibility, swelling strength, abrasion resistance test, anti-pilling, water penetration, abrasion resistance, anti-static, etc.

Second, chemical performance test

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

Third, the size change related test

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

Four, color fastness

Color fastness to soaping (small 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, color fastness to water, color fastness to light, color fastness to seawater, color fastness to saliva.

V. Component yarn test

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

Sixth, ecological textile control items

Prohibited azo dyes, carcinogenic dyes, allergenic dyes, extractable heavy metals, pentachlorophenol, organic chlorobenzene and chlorotoluene, free formaldehyde, organic tin compounds, prohibited phthalate plasticizers, hexavalent chromium, nickel release, total lead, total cadmium, pH value, color fastness, etc.
