Xim nrig yog hais txog qhov fading ntawm dyed fabric nyob sab nraud lwm yam (xws li dej, teeb, muab tshuaj, ntxuav, hwv thiab lwm yam) thaum siv los yog ua, thiab yog qhov tseem ceeb ntawm cov ntaub. Cov ntaub ntawv tuaj yeem tshwm rau ntau yam xws li lub teeb, ntxuav, ironing, hws, txhuam thiab tshuaj thaum lawv siv. Qee cov ntawv luam tawm thiab dyeing textiles kuj tau ua tiav tshwj xeeb xov, xws li cov pob zeb, cov nplaim hluav taws, xuab zeb, ntxhua khaub ncaws, thiab lwm yam, uas yuav tsum muaj xim ntawm cov ntawv luam tawm kom muaj qee qhov kev qaug zog.
Zoo thiab pluag xim nruj, ncaj qha ntsig txog tib neeg kev noj qab haus huv thiab kev nyab xeeb. Nyob hauv cov txheej txheem hnav cov khoom uas tsis muaj xim xim nruj, thaum nag los yog hws ntsib, cov pigment ntawm cov ntaub yuav poob thiab ploj. Ntawm lawv, cov molecules ntawm cov zas thiab cov hlau hnyav ions tej zaum yuav nqus tau los ntawm tib neeg lub cev los ntawm daim tawv nqaij thiab tiv thaiv kev mob ntawm tib neeg cov tawv nqaij. Ntawm qhov tod tes, nws yuav ua rau lwm cov khaub ncaws hnav hauv lub cev, lossis lwm cov khaub ncaws uas qias neeg thaum ntxuav nrog lwm cov khaub ncaws.
Feem ntau ntawm cov kev xeem tam sim no xws li International Standards Organization (ISO), American Association of Dyers thiab Chemists (AATCC), Nyiv (JIS), UK (BS) thiab ntau lwm cov qauv, feem ntau yog siv tau ntxhua, hws resistant, ironing resistant, huab cua resistant thiab lwm yam khoom.

Webbing ua zuam npuag, qhov kev sim yog xim tawv. Yog tias ib qho xim xim ntawm lub webbing khoom tsis mus txog qib uas tau teev tseg los ntawm tus txheej txheem, qhov webbing khoom tsis tsim nyog. Cov hauv qab no yog cov qauv webbing uas cov webbing yuav tsum ua raws li:
1. Ntxuav ceev yog siab dua 3.5, dhau qhov kev xeem ISO105-C01: 1989
2. Cov kab mob ceev nrooj yog siab dua 3.5, dhau qhov kev xeem ISO105-X12: 1993 xeem
3. Tiv thaiv kom ceev ceev ntawm 4 los yog siab dua, dhau ISO105-B02: 1994 xeem ntawv
Weaver lub webbing yuav ua tau los ntawm tus neeg yuav tsum tau. Peb tau cog lus tias yuav tsim cov webbing zoo tshaj plaws rau peb cov neeg tau txais. Tsuas xa tuaj rau peb.
