Nws nyob ntawm qhov kev ua tau zoo uas koj xav ua kom tiav. Yog hais tias lub zog thiab abrasion kuj zoo, polyester yog zoo. Yog hais tias lub shrinkage thiab photosensitivity yog zoo, acrylic yog zoo. Lub zog thiab abrasion tsis kam ntawm polyester qib thawj. Lub photosensitivity ntawm acrylic yog qhov zoo tshaj plaws ntawm tag nrho cov ntaub ntawv raw! Hais txog tus nqi, acrylic fiber yog kim! Hauv qab no yog ib qho kev qhia tshwj xeeb!

Polyester yog dav siv nyob rau hauv cov ntaub ntawv rooj thiab cov khoom lag luam. Nws yog qhov yooj yim heev los txiav txim siab qhov xwm txheej ntawm polyester, thiab nws tseem tuaj yeem nyob tiaj tus tom qab rov ntxuav dua.

1. Lub zog muaj zog. Lub zog ntawm luv fiber ntau yog 2.6 ~ 5.7 cN / dtex, thiab lub zog siab fiber ntau yog 5.6 ~ 8.0 cN / dtex. Vim nws qhov nqus dej tsawg, nws lub zog ntub dej yog qhov zoo ib yam li nws lub zog qhuav. Qhov cuam tshuam lub zog yog 4 npaug siab dua nylon thiab 20 npaug siab dua viscose fiber.

2. Zoo elasticity. Lub elasticity yog ze rau ntawm cov ntaub plaub. Thaum lub elongation yog 5% ~ 6%, nws yuav luag zoo tag nrho.

3. Thaum tshav kub kub tsis kam thiab thermal stability yog qhov zoo tshaj plaws ntawm cov khoom siv hluavtaws.

4. Polyester muaj lub ntsej muag du thiab zoo sib xws nrog cov molecules.

5. Zoo hnav tsis kam. Qhov kev txhuam tsis zoo tsuas yog qis dua rau nylon nrog qhov zoo tshaj plaws kev puas tsuaj, uas yog zoo dua li lwm yam ntuj fibers thiab hluavtaws fibers.

6. Lub teeb ua haujlwm zoo. Lub teeb tsis kam yog thib ob tsuas yog acrylic fiber.

7. Corrosion kuj. Nws tiv taus cov tshuaj bleaching, oxidants, hydrocarbons, ketones, roj av khoom thiab inorganic acids. Nws yog resistant rau dilute alkali thiab tsis ntshai ntawm pwm, tab sis yuav decomposed los ntawm kub alkali.

8. Cov dyeing tsis zoo, tab sis zoo xim ceev, tsis yooj yim rau ploj.

Cov txheej txheem tseem ceeb ntawm acrylic fiber ntau: polymerization → spinning → preheating → steaming → ntxuav → ziab → tshav kub → crimping → txiav → ntim.

Kev ua tau zoo ntawm polyacrylonitrile fiber ntau zoo ib yam li ntaub plaub, nrog zoo elasticity. Thaum nws ncav cuag 20%, qhov resilience tseem tuaj yeem khaws cia ntawm 65%. Nws yog fluffy, curly thiab mos, thiab nws qhov sov so yog 15% siab dua li cov ntaub plaub. Nws yog hu ua hluavtaws wool. Lub zog yog 22.1 ~ 48.5 cN / dtex, uas yog 1 ~ 2.5 npaug siab dua ntaub plaub. Nws muaj lub teeb ua haujlwm zoo heev. Nws tuaj yeem siv los ua cov ntaub thaiv, ntaub thaiv npog, tarpaulin, thiab cannon coat tom qab raug tshav ntuj rau ib xyoos. Nws tuaj yeem tiv taus acid, oxidant thiab cov organic hnyav, tab sis tsis muaj alkali tsis kam. Fiber softening kub yog 190 ~ 230 degree.
