1Q: Koj puas paub cov yam ntxwv cuam tshuam rau dyeing Performance ntawm Nylon?

A: 1. Kev cuam tshuam ntawm cov ntaub thiab cov qauv fiber ntau

Los ntawm qhov kev xav ntawm tag nrho cov dyeing thiab xov txheej txheem, feem ntau ncaj qha yog vim li cas cuam tshuam lub uniformity ntawm nylon dyeing yog lub uneven warp thiab weft ceev ntawm cov ntaub, sib txawv xov tooj suav, thiab sib txawv ntau lawm batches ntawm nylon fibers siv nyob rau hauv cov ntaub. Nws tuaj yeem cuam tshuam qhov kev ua haujlwm dyeing ntawm nylon, ua rau tsis sib xws dyeing.

Los ntawm qhov kev xav ntawm fiber ntau, cov qauv tshuaj ntawm nylon fiber ntau yog polyamide, thiab muaj qee cov amino pawg ntawm qhov kawg ntawm cov fiber ntau molecular saw. Cov yam ntxwv dyeing ntawm nylon cuam tshuam los ntawm cov tshuaj lom neeg thiab lub cev sib txawv ntawm cov fibers, uas yuav tshwm sim los ntawm kev tsim khoom lossis kev ua cov fibers. , lawv ncaj qha cuam tshuam rau cov khoom dyeing ntawm dyes. Cov tshuaj sib txawv los ntawm qhov sib txawv ntawm cov amino acid cov ntsiab lus ntawm cov fibers, uas tej zaum yuav raug tsim thaum lub sij hawm spinning txheej txheem, thermal drawing txheej txheem, los yog paralleling txheej txheem.

Qhov sib txawv ntawm cov amino pawg cov ntsiab lus tuaj yeem ua rau muaj qhov sib txawv ntawm cov xim dye uptake tus nqi thiab tshwj xeeb tshaj yog qhov kawg adsorption ntawm anionic dyes, uas tsuas yog txo qis los ntawm kev ceev faj ntawm cov txheej txheem ntau lawm.

Qhov sib txawv ntawm cov qauv ntawm lub cev ntawm cov xov paj feem ntau suav nrog ob yam: ntawm ib sab, nws los ntawm tag nrho lub cev sib txawv ntawm cov xov paj, suav nrog cov xov tooj suav, cov xov tooj fibers hauv cov xov paj lossis cov denier ntawm fiber ntau, thiab qhov curling ntawm qhov kawg ntawm ib qho fiber ntau hauv cov xov paj. Los yog qhov sib txawv ntawm cov crimps ntawm ntau fiber ntau xaus; Ntawm qhov tod tes, nws los ntawm heterogeneity ntawm cov qauv supramolecular tsim thaum lub sij hawm ua cov nylon fibers, xws li crystallinity nyob rau hauv fiber, qhov sib txawv ntawm orientation, los yog cov tawv nqaij-core qauv. sib npaug. Thaum dyeing fabrics ua los ntawm chemically los yog lub cev sib txawv nylon fibers, ib tug yam ntxwv weft xim stripe yog yooj yim tsim.

2. Kev cuam tshuam ntawm pretreatment tej yam kev mob

Kev xaiv tsis raug ntawm kev kho mob ua ntej rau cov ntaub nylon kuj yog ib qho tseem ceeb ua rau dyeing tsis sib xws. Kev kho tsis zoo ntawm cov ntaub ntawv feem ntau suav nrog: kev kho cov ntaub tsis sib xws, uas ua rau muaj qhov sib txawv ntawm cov khoom adsorption ntawm fibers, ua rau dyeing thiab plaub hau poob; Cov cua kub ceev ntawm nylon filaments nyob rau hauv cov txheej txheem pretreatment ntawm jigger dyeing tshuab ua rau cia li shrinkage ntawm nylon filaments, los yog kub hloov thaum lub sij hawm tshav kub teeb Inhomogeneity yuav ua rau cov qauv sib txawv nyob rau hauv nylon fibers, thiab uneven dyeing yuav tshwm sim thaum lub sij hawm dyeing txheej txheem.

3. Kev cuam tshuam ntawm dyeing tej yam kev mob

① cuam tshuam ntawm qhov kub thiab txias

Nylon yog cov thermoplastic fiber ntau. Yog li ntawd, qhov dyeing tus nqi ntawm fiber ntau muaj kev sib raug zoo nrog qhov kub thiab txias, thiab qhov kub ntawm dyeing yuav tsum siab tshaj qhov kub hloov ntawm cov iav fiber ntau (35-50 degree ). Nylon fibers pib nqus dyes ntawm 40 degree. Raws li qhov kub nce, qhov dyeing tus nqi nrawm, thiab cov txheej txheem dyeing tuaj yeem ua tiav ntawm 100 degree. Txawm hais tias dyeing tuaj yeem ua tiav thaum qhov kub thiab txias yog 100 degree, txuas ntxiv kom sov yuav pab tau hauv kev tsiv teb tsaws ntawm dyes, kom qib dyeing tuaj yeem txhim kho. Qee cov kws tshawb fawb ntseeg tias cov xim ntawm cov nylon fibers dyed nrog acid dyes muaj feem xyuam rau qhov kub thiab txias. Thaum qhov kub siab tshaj qhov hloov pauv ntawm iav, qhov kev txav ntawm cov saw hlau macromolecular hauv fiber ntau yog txhim kho, thiab cov fiber ntau qhib, tso cai rau cov xim nkag mus rau hauv cov fiber ntau thiab hnov ​​​​mob nrog lub davhlau ya nyob twg amino cation, tab sis yog tias qhov cua sov. tsis zoo tswj, nws yog ib qho yooj yim los tsim uneven dyeing Phenomenon.

② Kev cuam tshuam ntawm pH tus nqi

Thaum dyeing nylon fiber ntau, thaum pH tus nqi ntawm cov tshuaj dye yog qhov siab, cov xim tsis tshua muaj xim; Thaum pH tus nqi ntawm cov tshuaj dyeing poob mus rau ib qho nqi, cov dye pib dye, thiab sai sai mus txog saturation, txuas ntxiv txo tus nqi pH ntawm dyeing hmo ntuj, cov dye uptake tsis nce ntau; Txawm li cas los xij, thaum tus nqi pH txo qis dua mus rau 3, qhov dye uptake nce sharply, thiab super-sib npaug adsorption tshwm sim. Thaum nylon fiber ntau yog dyed nyob rau hauv cov xwm txheej ntawm tus nqi pH tsawg heev, nws tseem yuav hydrolyzed, tshwj xeeb tshaj yog tom qab super-sib npaug adsorption, pH tus nqi hauv fiber ntau yog qis dua li hauv cov tshuaj, hydrolysis yog nrawm, thiab ntau cov amino pawg. yog tsim tom qab hydrolysis. Nrog rau kev nkag mus tau ntau dua, ntau cov xim tuaj yeem adsorbed, ua rau nws yooj yim dua los tsim cov dyeing tsis sib xws. Yog li ntawd, raws li qhov teeb meem tiag tiag, tus nqi pH tuaj yeem hloov kho kom txo tau qhov tshwm sim ntawm cov xim paj.

③ Kev cuam tshuam ntawm cov tshuaj ntxiv

Nylon fibers feem ntau dyed nrog acid dyes, thiab cov theem ntawm cov kua qaub dyes feem ntau muaj xws li anionic, cationic thiab nonionic. Cov anionic leveling tus neeg saib xyuas muaj qee yam affinity rau cov fiber ntau hauv cov kua qaub nruab nrab, thiab muaj cov nyhuv dyeing ntawm fiber ntau nrog cov xim anion. Nws qhov kev sib raug zoo yog qis dua li ntawm cov xim anion, tab sis tus nqi diffusion yog sai dua li cov xim anion. Thaum pib ntawm dyeing, anionic leveling tus neeg sawv cev sib tw nrog cov dyeing rau lub rooj zaum dyeing. Vim yog qhov nrawm nrawm, lawv zas cov fiber ntau ua ntej dye anion, ua ke nrog -NH ntawm cov fiber ntau, thiab tom qab ntawd maj mam hloov los ntawm cov xim anion nrog cov affinity siab rau cov fiber ntau. Hauv qab no, qhov no txo ​​qis tus nqi dyeing thawj zaug ntawm cov dyeing thiab ua tiav qib dyeing nyhuv.

Cationic thiab non-ionic leveling agents ua ke nrog dye anions kom txo cov concentration ntawm dye anions, thiab maj mam tso dye anions thaum lub sij hawm dyeing txheej txheem los ua ib tug leveling nyhuv. Tsis tas li ntawd, yam xws li lub sij hawm dyeing, dye compatibility, dye cawv concentration, da dej piv thiab dye cawv ncig tus nqi kuj yuav cuam tshuam rau qib dyeing nyhuv ntawm nylon dyeing.
