Cov xim ceev ceev ntawm textiles rau rubbing tuaj yeem muab faib ua kom qhuav nrawm nrawm thiab ntub ntub nrawm nrawm.

Xim ceev rau rubbing yog hais txog qib xim fading ntawm dyed fabrics tom qab rubbing, thiab yog ib qho kev ntsuam xyuas ntawm qhov tsis kam ntawm dyes rau txhua yam kev sib txhuam.

Cov yam ntxwv cuam tshuam rau xim ceev rau txhuam:

ib. Hom ntaub nrog cov xim tsis zoo kom qhuav qhuav: ntxhib lossis txhuam nto, cov ntaub nplaum, cov ntaub tawv xws li linen, denim fabrics, pigment-printed fabrics, dyes los yog lwm yam xim uas muaj nyob rau saum npoo yog av los ntawm qhuav qhuav, Los yog qee cov xim fibers tau tawg los ua cov xim xim, uas txo cov qib xim ceev kom qhuav qhuav; Nyob rau hauv tas li ntawd, rau sanded los yog tsa fabrics, muaj ib tug tej lub kaum sab xis ntawm lub fluff ntawm qhov chaw thiab qhov chaw ntawm daim ntaub abrasive, uas tsis yog tib yam. Kev sib txhuam tsis kam ntawm daim ntaub abrasive nce, thiab xim ceev kom qhuav abrasion kuj txo.

b. Cellulosic fiber ntau yog feem ntau dyed nrog reactive dyes. Muaj ob lub laj thawj vim li cas cov dyes ntawm cov ntaub ntawv xeem tsiv mus rau daim ntaub abrasive:

▲ Cov dej-soluble dyes raug xa mus rau daim ntaub abrasive thaum ntub dej. Cov reactive dyes thiab cellulose fibers yog khi los ntawm covalent bonds. Hom ntawm daim ntawv cog lus no muaj zog heev thiab yuav tsis tawg vim kev sib txhuam. Cov dyes khi rau cellulose fibers los ntawm van der Waals quab yuam (hu ua floating xim) yuav raug xa mus rau cov ntaub abrasive nyob rau hauv ntub dej ntub, ua rau cov ntub ntub ntub ceev ceev.

▲ Cov dyed fibers tau tawg thaum lub sij hawm txhuam, tsim cov xim me me ntawm cov xim fiber ntau thiab xa mus rau daim ntaub abrasive, ua rau cov xim tsis zoo rau ntub dej ntub.

c. Cov xim nrawm nrawm rau ntub dej ntawm cov ntaub dyed reactive muaj ntau yam ua rau qhov tob ntawm dyeing. Thaum dyeing cov xim tsaus, qhov concentration ntawm dyes siv yog siab dua, vim hais tias ntau dyes tsis tuaj yeem ua ke nrog fibers thiab tuaj yeem tsuas sau rau ntawm cov fibers. Nws dhau los ua cov xim ntab, uas cuam tshuam rau cov xim nrawm ntawm cov ntaub kom ntub dej. Cov degree ntawm pretreatment ntawm cellulose fiber ntaub ncaj qha cuam tshuam cov xim ceev rau ntub dej ntub, mercerizing, singeing, scouring, bleaching thiab lwm yam pretreatments yuav ua rau cov ntaub nto du, txo kev sib txhuam, thiab txhim kho cov xim ceev kom ntub cov ntaub.

d. Rau lub teeb thiab nyias polyester fabrics, thaum qhuav qhuav, vim hais tias cov ntaub yog xoob, nyob rau hauv qhov kev txiav txim ntawm kev sib txhuam, cov ntaub yuav ib nrab plam, uas yuav ua rau kom muaj kev sib txhuam; tab sis cov ntaub zoo li no yog cov xim ntub dej ntub dej. Hauv kev sim ceev ceev, vim tias tsis muaj dej nqus ntawm polyester, dej ua lub luag haujlwm lubricating thaum ntub sib tsoo, yog li qhov no, cov xim ceev ceev ntawm cov ntaub ntub dej sib tsoo zoo dua li cov xim ceev kom qhuav sib tsoo. Qee cov xim tsaus nti xws li dub, liab lossis xiav navy muaj qhov ua tau zoo dua. Txawm li cas los xij, rau cov ntaub corduroy, nyob rau hauv cov dej ntub dej, vim siv cov dyes thiab luam ntawv thiab dyeing txheej txheem, cov xim ib txwm ceev kom ntub dej tsuas yog kwv yees li 2 qib, uas tsis zoo dua li cov xim ceev kom qhuav qhuav.

e. Lub softener ntxiv nyob rau hauv cov txheej txheem tiav plays lub luag hauj lwm lubricating, uas yuav txo tau cov coefficient ntawm kev sib txhuam thiab dye shedding. Cov cationic softener thiab anionic reactive dyes yuav hnov ​​​​mob tsim lub pas dej, uas txo cov solubility ntawm cov dye thiab txhim kho cov ntaub. Kev ntub dej nrawm nrawm. Cov tshuaj Softeners nrog cov pab pawg hydrophilic tsis yog qhov tsim nyog rau kev txhim kho cov ntub dej nrawm nrawm.
