Npuag paub: cua thiab UV tsis kam ntawm nylon ntaub

Nylon ntaub

Nylon ntaub yog tsim los ntawm nylon fiber, uas muaj lub zog zoo heev, hnav tsis kam thiab lwm yam khoom, thiab cov dej noo rov qab yog li ntawm 4.5% - 7%. Cov ntaub woven los ntawm nylon ntaub muaj ib tug mos mos, lub teeb kev ntxhib los mos, xis hnav, zoo hnav zoo, thiab plays lub luag hauj lwm tseem ceeb nyob rau hauv cov tshuaj fibers.

Nrog rau kev tsim cov tshuaj fiber ntau, qhov ntxiv tus nqi ntawm lub teeb yuag thiab kev nplij siab ntawm nylon thiab nylon blended fabrics tau zoo heev, uas yog tshwj xeeb tshaj yog haum rau sab nraum zoov fabrics, xws li down tsho thiab roob suits.

Cov yam ntxwv ntawm fiber ntau

Piv nrog cov paj rwb ntaub, nylon ntaub muaj lub zog zoo dua qub thiab muaj zog hnav tsis kam.

Lub ultra-fine denier nylon ntaub qhia nyob rau hauv daim ntawv no kuj muaj cov kev ua ntawm anti pawg los ntawm calendering thiab lwm yam txheej txheem.

Los ntawm dyeing thiab xov, technology thiab additives, cov ntaub nylon muaj cov yam ntxwv ua haujlwm ntawm dej, cua thiab UV tsis kam.

Tom qab dyeing nrog acid dyes, nylon muaj cov xim ceev ceev.

Kev siv thev naus laus zis los tiv thaiv txaws, tiv thaiv cua thiab tiv thaiv UV dyeing

Txias reactor

Thaum lub sij hawm weaving txheej txheem ntawm grey ntaub, thiaj li yuav txo tau qhov tsis xws luag, xyuas kom meej lub continuation ntawm weaving, thiab ua kom lub smoothness ntawm warp kev ua tau zoo, cov ntaub yuav raug kho nrog sizing thiab oiling. Qhov sizing muaj qhov cuam tshuam tsis zoo rau dyeing thiab xov ntawm cov ntaub. Yog li ntawd, cov ntaub yuav raug tshem tawm los ntawm txias stacking ua ntej dyeing los xyuas kom meej qhov kev tshem tawm ntawm impurities xws li sizing thiab xyuas kom meej dyeing zoo. Peb txais yuav cov txheej txheem txias pawg + kev ua haujlwm siab tiaj tus desizing dej ntxuav rau kev kho ua ntej.

Ntxuav

Cov roj silicon tshem tawm los ntawm pawg txias yuav tsum tau kho degreasing ntxiv. Kev kho deoiling tiv thaiv cov roj silicone thiab cov ntaub los ntawm crosslinking thiab adsorbing ntawm nylon yarn thaum kub kub kub tom qab dyeing, uas ua rau loj uneven dyeing ntawm tag nrho cov ntaub nto. Cov txheej txheem ntxuav dej siv lub siab-zaus ultrasonic kev co ntawm cov dej ntxhua khaub ncaws kom tshem tawm cov impurities ntawm cov ntaub tiav los ntawm pawg txias. Feem ntau, muaj impurities xws li degraded, saponified, emulsified, alkali hydrolyzed slurry thiab roj nyob rau hauv lub txias pawg. Ceev cov tshuaj degradation ntawm oxidation khoom thiab alkali hydrolysis los npaj rau dyeing.

Predetermined hom

Nylon fiber ntau muaj crystallinity. Los ntawm hom predetermined, lub crystalline thiab non crystalline cheeb tsam yuav tsum tau teem nyob rau hauv kev txiav txim, tshem tawm los yog txo cov kev nyuaj siab tsis sib xws uas ua los ntawm nylon fiber thaum lub sij hawm spinning, tsim thiab weaving, thiab zoo txhim kho cov dyeing uniformity. Hom predetermined kuj tseem tuaj yeem txhim kho qhov flatness thiab wrinkle tsis kam ntawm cov ntaub, txo cov wrinkle print tshwm sim los ntawm kev txav ntawm cov ntaub hauv jigger thiab xim wrinkle luam tawm tom qab retraction, thiab ua kom tag nrho cov kev sib koom tes thiab sib xws ntawm cov ntaub. Vim hais tias cov ntaub ntawv polyamide yuav ua rau lub davhlau ya nyob twg cov amino pawg ntawm qhov kub thiab txias, nws yooj yim heev rau oxidized thiab ua rau cov dyeing kev ua tau zoo, yog li yuav tsum muaj ib qho me me ntawm cov kub kub yellowing tus neeg sawv cev ntawm lub predetermined hom theem kom txo tau yellowing ntawm lub ntaub.

Dyees

Los ntawm kev tswj tus neeg sawv cev theem, dyeing kub, kub nkhaus thiab pH tus nqi ntawm dyeing tov, lub hom phiaj ntawm leveling dyeing tuaj yeem ua tiav. Txhawm rau txhim kho cov dej tsis zoo, roj repellency thiab stain kuj ntawm cov ntaub, eco puas tau ntxiv rau hauv cov txheej txheem dyeing. Eco puas yog ib qho anionic auxiliary thiab cov khoom siv nano siab molecular, uas tuaj yeem txuas nrog cov txheej fiber ntau nrog kev pab cuam ntawm dispersant hauv dyeing. Nws reacts nrog cov tiav lawm organic fluorine resin nyob rau saum npoo ntawm fiber, zoo heev txhim kho cov roj repellency, dej repellency, antifouling thiab ntxuav tsis kam.

Nylon fabrics feem ntau yog tus cwj pwm los ntawm qhov tsis zoo UV tsis kam, thiab UV absorbers tau ntxiv rau hauv cov txheej txheem dyeing. Txo cov UV nkag mus thiab txhim kho UV tiv thaiv ntawm cov ntaub.

Kev kho

Txhawm rau txhim kho cov xim nrawm ntawm nylon ntaub, anionic kho tus neeg sawv cev tau siv los kho cov xim ntawm nylon ntaub. Cov xim kho tus neeg sawv cev yog ib qho anionic auxiliary nrog loj molecular hnyav. Vim yog hydrogen daim ntawv cog lus thiab van der Waals quab yuam, cov xim kho tus neeg sawv cev txuas mus rau txheej txheej ntawm cov fiber ntau, txo cov kev tsiv teb tsaws ntawm cov molecules hauv fiber ntau, thiab ua tiav lub hom phiaj ntawm kev txhim kho qhov ceev ceev.

Tom qab hloov kho

Txhawm rau txhim kho qhov drilling tsis kam ntawm nylon ntaub, calendering tiav tau ua tiav. Calendering xov yog ua kom cov ntaub yas thiab "ntws" tom qab tau rhuab rau hauv lub nip los ntawm cov elastic mos cov menyuam thiab cov hlau kub cov menyuam los ntawm cov nto shearing thiab rubbing txiav txim, yog li ntawd lub nruj ntawm cov ntaub nto yuav tsum uniform, thiab cov ntaub nto hu los ntawm cov hlau rau cov menyuam yog du, thiaj li yuav txo tau qhov sib txawv ntawm lub weaving point, ua tiav cov huab cua zoo tagnrho ntawm cov ntaub thiab txhim kho cov smoothness ntawm cov ntaub nto.

Calendering finishing yuav muaj kev cuam tshuam rau lub cev lub cev ntawm cov ntaub, thiab tib lub sijhawm, nws yuav txhim kho cov khoom tiv thaiv pawg, zam cov tshuaj txheej txheej kho ntawm ultra-fine denier fibers, txo tus nqi, txo qhov hnyav. ntaub, thiab ua tau zoo heev anti pawg khoom.

Xaus:

Txias pawg dej ntxuav thiab teeb dyeing pretreatment raug xaiv los txo qhov kev pheej hmoo ntawm dyeing.

Ntxiv UV absorbers tuaj yeem txhim kho lub peev xwm tiv thaiv UV thiab txhim kho cov ntaub zoo.

Dej thiab roj repellency yuav zoo heev txhim kho xim ceev ntawm fabrics.

Calendering yuav txhim kho lub windproof thiab anti-pile kev ua tau zoo ntawm cov ntaub, txo qhov kev pheej hmoo ntawm txheej thiab txo tus nqi, txuag hluav taws xob thiab emission txo.
