Textile Xav

Kev xav thiab tidying ntawm textiles yeej ib txwm yog ib feem tseem ceeb ntawm dyeing factories. Kev xav ntawm textiles muaj feem xyuam rau fiber ntau raw cov ntaub ntawv, xov paj ntau yam, ntaub thickness, hnyav, microstructure thiab dyeing thiab xov technology. Cov kab lus no feem ntau qhia txog qhov nyuaj thiab muag muag hauv cov ntaub zoo li xov.

Textile xav

(1) Ncaj nws tawm

Kev ua tiav nyuaj yog kev siv cov yeeb yaj kiab ua cov khoom siv polymer ua los ntawm cov ntaub ntawv tiav impregnated rau ntawm cov ntaub, kom nws ua raws li cov ntaub ntawv, thiab tom qab ziab, ib zaj duab xis yog tsim los npog cov ntaub, yog li muab cov ntaub ntawv. fabric ib tug du, tuab, plump thiab tawv zoo li.

Nthuav xov tseem hu ua sizing xov. Cov slurry muaj xws li dextrin ntawm cov hmoov txhuv nplej siab thiab cov hmoov txhuv nplej siab, cov hmoov txhuv nplej siab soluble, nrog rau sodium alginate, bovine gum, carboxymethylcellulose (CMC), sodium cellulose zincate, polyvinyl cawv (PVA), polyacrylic acid, thiab lwm yam. Cov slurries saum toj no kuj tuaj yeem sib xyaw. raws li kev xav tau. Thaum npaj cov slurry, ib qho muab tub lim kuj tseem ntxiv kom qhov hnyav ntawm cov ntaub thiab sau cov qhov ntawm daim ntaub kom cov ntaub du thiab tuab. Talc, kaolin thiab bentonite feem ntau yog siv los ua fillers. Txhawm rau tiv thaiv qhov lwj ntawm slurry, cov tshuaj tua kab mob xws li phenol thiab ethylnaphthol kuj tau ntxiv. Thaum sizing cov xim ntaub, dyes los yog coatings ntawm cov xim zoo sib xws yuav tsum tau ntxiv. Tom qab sizing nrog cov hmoov txhuv nplej siab tiav, nws tsis tuaj yeem tiv taus kev ntxuav thiab tuaj yeem tau txais cov teebmeem ib ntus.

Siv hluavtaws slurry sizing, koj tuaj yeem tau txais cov nyhuv zoo dua thiab tawv.

Piv txwv li, polyvinyl cawv nrog high alcohololysis degree thiab polymerization degree ntawm txog 1700 yog siv los ua paj rwb ntaub sizing, thiab thaum ntxuav ntawm cov dej kub hauv qab 80 degree tom qab ua tiav, nws muaj zoo washability thiab zoo smoother thiab stiffer. Rau hydrophobic hluavtaws fibers, polyvinyl cawv nrog tsawg alcohololysis thiab polymerization degree yog tsim nyog.

Polyester paj rwb blended fabrics tuaj yeem tov nrog ob hom polyvinyl cawv hauv ib qho kev faib ua feem. Cov ntaub yog kho nrog cellulose sodium zincate slurry, thiab tom qab ntawd kho nrog dilute sulfuric acid, cellulose sodium zincate yog cais rau hauv cellulose thiab tso rau saum npoo ntawm ntaub, uas tuaj yeem tau txais cov txiaj ntsig hemp tiav nrog zoo ntxuav thiab tawv. Tsis tas li ntawd, qee qhov thermoplastic resin emulsions, xws li polyethylene, polyacrylic emulsion, ntaub impregnated emulsions, tom qab ziab ntawm cov ntaub los ua ib zaj duab xis tsis tu ncua hauv dej thiab khov kho, nrog ntau yam resin tuaj yeem muab cov ntaub tawv. los yog muag muag, hluavtaws slurry kuj yuav tov nrog ntuj slurry daim ntawv thov.

Npuag sizing thiab xov yog nyob ntawm tus nqi ntawm slurry thiab yuav tsum tau siv cov dip dov sizing, txhuam nto dov sizing thiab ib leeg-sab sizing txoj kev. Tom qab cov ntaub yog qhov loj me, nws feem ntau qhuav los ntawm lub nruas tshuab ziab khaub ncaws, tab sis qhov tshwm sim ntawm cov tawv nqaij los yog slurry zaj duab xis detachment yuav tsum tau tiv thaiv. Thaum sizing ntawm ib sab, tus nqi ntawm slurry ntawm cov ntaub yog siab, thiab nws yog ib qho tseem ceeb kom xav txog kev tiv thaiv cov phenomena saum toj no.

(2) Soft finishing

Ib txoj hauv kev ua kom zoo nkauj yog ua kom cov ntaub zoo li softer los ntawm kev ua haujlwm, feem ntau yog siv peb-cov menyuam roj hmab daim pam shrinking tshuab, tsim nyog txo qhov kev khiav hauj lwm kub, siab, ceev, koj tuaj yeem tau txais kev xav softer, yog tias cov ntaub los ntawm ib tug xov tooj ntawm passive square qhia rods, thiab ces nkag mus rau lub mos dov taw tes ntawm lub calender rau calendering, koj muaj peev xwm kuj tau ib tug du thiab mos xav, tab sis cov mos finishing txoj kev no tsis resistant rau ntxuav, feem ntau ntawm cov tam sim no siv softener rau soft finishing.

Tom qab cov ntaub sib npaug nqus cov roj me me, nws tuaj yeem txo qhov kev sib txhuam ntawm cov xov paj thiab fibers hauv cov ntaub thiab nruab nrab ntawm cov ntaub thiab tib neeg tes, thiab muab cov ntaub mos muag, thaum muab tag nrho thiab drape, thiab txhim kho. kev txiav thiab xaws.

Tam sim no, lub tshuab ntxhua khaub ncaws uas tuaj yeem ruaj khov nrog cov fibers tau siv dav. Roj thiab paraffin wax ua los ntawm emulsion los yog saponification tom qab siv, xws li softeners muaj ib tug dav qhov chaw, tsis tshua muaj nqi, yooj yim rau siv, tab sis tsis resistant rau ntxuav, thiab yooj yim los tsim greasy xav thiab adsorb roj, ntau yam tseem siv yog emulsion ciab. (kua ciab 10 feem pua, stearic acid, glyceryl stearate, tiaj tus ntxiv O, triethanolamine 1 feem pua ​​​​txhua, muaj li ntawm dej), mercerized paste (stearic acid 10 feem pua, saponified nrog borax, ammonia, soda tshauv, thiab lwm yam).

Ntau cov khoom lag luam hauv surfactants kuj tseem siv tau los ua softeners, roj liab hauv anion surfactants, 1631 surfactants hauv cov khoom zoo surfactants, thiab lwm yam, yog yooj yim soluble hauv dej, yooj yim siv, tab sis tseem tsis resistant rau ntxuav. Washable softeners muaj xws li cov dej tsis zoo PF, silicones, thiab lwm yam. Ib qho kawg ntawm cov qauv ntawm cov softener no muaj ib pab pawg uas tuaj yeem cuam tshuam nrog cellulose hydroxyl pawg, thiab tom qab cov tshuaj tiv thaiv, cov softener molecule yog tsau rau ntawm cov fiber ntau, ua si. tib lub luag haujlwm muag muag xws li roj ciab thiab surfactant, thiab muaj kev ntxuav zoo.

Cov khoom siv los ua softener yuav tsum tsis muaj ntxhiab tsw phem thiab tsis muaj kev cuam tshuam rau cov xim dawb, xim thiab ceev ntawm cov ntaub. Thaum siv cation softeners, cov ntaub yuav tsum tau ntxuav kom huv si thiab tsis muaj anion surfactants kom tsis txhob muaj kev sib nrig sib cuam tshuam. Tsis muaj teeb meem dab tsi ntawm softener, qhov ntau npaum li cas yuav tsum yog nruab nrab, ntau dhau yuav ua rau dej tawm thiab greasy thiab nplaum.

Rau textile fabrics, ua ib txoj hauj lwm zoo ntawm tes xov, tus nqi ntawm cov ntaub thiab kev lag luam muaj koob meej tuaj yeem txhim kho zoo heev. Yog li ntawd, cov tuam txhab luam ntawv thiab dyeing thiab khaub ncaws cov tuam txhab lag luam yuav tsum tau them nyiaj rau tag nrho cov kev xav ntawm kev ua tiav!
