Nylon fiber yog ib hom hluavtaws fiber ntau, nws cov khoom tseem ceeb yog polyamide. Cov qauv molecular ntawm nylon fiber ntau muaj cov yam ntxwv hauv qab no: 1. Cov molecule ntawm nylon yog tsim los ntawm polyamide saw thiab hloov, thiab polyamide saw yog nws lub ntsiab structural unit. Polyamide chains feem ntau yog tsim los ntawm aliphatic binary amines thiab dibasic acids, feem ntau yog sulfite anhydride thiab caprolactam. Ntau pawg amide (-Conh -) muaj nyob hauv cov molecules ntawm polyamide fiber, thiab cov pab pawg no txuas nrog amide bonds.
Nylon fiber yog ib hom hluavtaws fiber ntau, nws cov khoom tseem ceeb yog polyamide. Cov qauv molecular ntawm nylon fiber ntau muaj cov yam ntxwv hauv qab no:
1. Lub polyamide molecule yog tsim los ntawm polyamide saw thiab hloov, thiab polyamide saw yog nws lub ntsiab structural unit. Polyamide chains feem ntau yog tsim los ntawm aliphatic binary amines thiab dibasic acids, feem ntau yog sulfite anhydride thiab caprolactam. Ntau pawg amide (-Conh -) muaj nyob hauv cov molecules ntawm polyamide fiber, thiab cov pab pawg no txuas nrog amide bonds.
2, polyamide fiber ntau molecules muaj ntau methyl thiab methylene pawg, cov pab pawg no ua polyamide molecules muaj hydrophilicity zoo, yooj yim rau stain.
3. Cov saw hlau polyamide hauv polyamide molecule raug txiav txim siab heev, ua rau thaj tsam crystalline, yog li cov polyamide fiber ntau lub cev thiab cov khoom siv zoo heev, xws li lub zog siab thiab elasticity.
4, nylon fiber ntau muaj thermal stability thiab hnav tsis kam, tuaj yeem tswj lub cev zoo ntawm qhov kub thiab txias, tsis yooj yim rau hnav.
Cov qauv molecular ntawm polyamide fiber ntau yog tsim los ntawm polyamide saw thiab pab pawg neeg hloov, polyamide saw yog nws lub ntsiab qauv. Vim muaj ntau pawg amide thiab methyl / methylene pawg hauv nws cov molecules, nws muaj hydrophilicity zoo thiab yooj yim staining.
Vim hais tias nylon fiber ntau muaj lub cev zoo thiab cov khoom siv hluav taws xob zoo, tiv thaiv tshav kub, hnav tsis kam thiab yooj yim staining thiab lwm yam zoo, nws yog dav siv nyob rau hauv ntau yam teb, ib co ntawm cov tseem ceeb daim ntawv thov teb muaj xws li:
1, textile teb: tuaj yeem siv los tsim ntau hom ntaub thiab textiles, xws li ris tsho hauv qab, thom khwm, ncaws pob, swimsuit, xws li hnav, khaub ncaws ua haujlwm, thiab lwm yam. kev pab cuam lub neej thiab kev nplij siab.
2. Kev lag luam teb: Nws kuj yog siv dav hauv kev lag luam, xws li kev tsim cov rooj zaum hauv tsheb, siv lub rooj zaum, lub log tsheb, cov hlua muaj hlua, lim thiab lwm yam khoom.
3, lub teb ntawm cov ntaub ntawv ntim: tuaj yeem siv los tsim ntau yam khoom ntim, xws li cov ntaub ntawv muaj zog, fiberboard, gasket, thiab lwm yam, nws lub zog siab thiab hnav tsis kam thiab lwm yam khoom muaj peev xwm tiv thaiv cov khoom ntim, ua rau cov khoom ntim khoom zoo. ntim ntau ruaj.
4, kho kom zoo nkauj hauv tsev: kuj tuaj yeem siv los tsim ntau yam khoom siv kho kom zoo nkauj hauv tsev, xws li ntaub pua plag, rooj zaum ntaub, ntaub, ntaub pua chaw, thiab lwm yam.
5, kev kho mob: tuaj yeem siv rau hauv kev tsim cov khoom siv kho mob, xws li cov ris tsho phais, qhov ncauj qhov ntswg, lim tshuaj, thiab lwm yam, nws lub zog siab thiab kub tsis kam thiab lwm yam khoom tuaj yeem ua kom muaj kev nyab xeeb thiab kev pabcuam lub neej ntawm cov khoom siv khomob no.
