Polypropylene yog dab tsi?

1. ntau yam

Cov ntau yam ntawm polypropylene fiber ntau muaj xws li filament (xws li undeformed filament thiab bulky deformed filament), staple fiber, mane fiber, membrane-split fiber, hollow fiber, profiled fibers, ntau yam puas fibers thiab non-woven fabrics.Nws yog tsuas yog siv los ua cov ntaub pua plag (xws li cov ntaub pua plag hauv qab thiab suede), cov ntaub dai kom zoo nkauj, rooj tog ntaub, ntau yam hlua, strips, nuv ntses nets, roj-absorbing felts, lub tsev cov ntaub ntawv, cov ntaub ntawv ntim thiab cov ntaub ntawv, xws li lim ntaub thiab hnab ntaub.Tsis tas li ntawd, nws yog dav siv hauv khaub ncaws.Nws tuaj yeem sib xyaw nrog ntau cov fibers los ua ntau hom kev sib xyaw ua ke.Tom qab knitting, nws tuaj yeem ua rau hauv lub tsho, tsho sab nrauv, khaub ncaws ncaws pob, thom khwm, thiab lwm yam. Cov ntaub qhwv ua los ntawm polypropylene hollow fiber yog lub teeb, sov thiab elastic.

2. Cov khoom siv tshuaj

Lub npe scientific ntawm polypropylene fiber yog tias nws yaj nyob ze ntawm cov nplaim taws, yog nplaim taws, kub hnyiab tawm ntawm qhov hluav taws kub thiab tawm cov pa taws dub.Sab saum toj kawg ntawm nplaim taws yog daj thiab qis kawg yog xiav, muab cov ntxhiab tsw ntawm cov roj av.Tom qab hlawv, cov tshauv yog tawv, puag ncig thiab daj daj xim av, uas tsis yooj yim thaum twisted ntawm tes.

3. Lub cev muaj zog

Lub dav hlau longitudinal ntawm morphology polypropylene fiber yog tiaj thiab du, thiab hla ntu yog puag ncig.

Qhov zoo tshaj plaws ntawm qhov ntom ntom polypropylene fiber ntau yog nws lub teeb kev ntxhib los mos, nws qhov ntom tsuas yog 0.91g / cm3, uas yog qhov sib sib zog nqus ntawm cov tshuaj fiber ntau, yog li tib qhov hnyav polypropylene fiber ntau tuaj yeem tau txais thaj tsam ntau dua li lwm cov fibers.

Tensile polypropylene fiber ntau muaj zog, loj elongation, siab pib modulus thiab zoo heev elasticity.Yog li ntawd, polypropylene fiber ntau muaj kev hnav zoo.Tsis tas li ntawd, lub zog ntub dej ntawm polypropylene yog qhov sib npaug ntawm lub zog qhuav, yog li nws yog ib qho khoom siv zoo tshaj plaws rau kev ua nuv ntses nets thiab cables.

Thiab muaj lub teeb hygroscopicity thiab dyeability, zoo warmth tuav;Yuav luag tsis muaj noo noo nqus, tab sis muaj peev xwm nqus tau zoo, pom tseeb noo noo nqus thiab hws;Polypropylene fiber ntau muaj qhov nqus dej me me, yuav luag tsis muaj qhov nqus dej noo, thiab cov dej noo rov qab los nyob rau hauv huab cua huab cua yog ze rau xoom.Txawm li cas los xij, nws tuaj yeem nqus dej vapor los ntawm capillaries hauv cov ntaub, tab sis nws tsis muaj qhov nqus dej.Polypropylene fiber muaj qhov tsis zoo dyeability thiab tsis tiav chromatography, tab sis nws tuaj yeem tsim los ntawm cov txheej txheem ntawm cov tshuaj pleev xim.

Acid-thiab alkali-resistant polypropylene muaj tshuaj zoo corrosion kuj.Dhau li ntawm cov concentrated nitric acid thiab concentrated caustic soda, polypropylene muaj kev tiv thaiv zoo rau cov kua qaub thiab alkali, yog li nws tsim nyog siv los ua cov khoom siv lim thiab ntim khoom.

Lub teeb ceev ceev, thiab lwm yam. Polypropylene muaj lub teeb tsis zoo, tsis zoo thermal stability, yooj yim aging thiab tsis muaj zog rau ironing.Txawm li cas los xij, qhov kev tiv thaiv kev laus tuaj yeem txhim kho los ntawm kev ntxiv cov tshuaj tiv thaiv kev laus thaum lub sij hawm spinning.Tsis tas li ntawd, polypropylene muaj cov hluav taws xob zoo, tab sis nws yooj yim los tsim hluav taws xob zoo li qub thaum ua.Polypropylene muaj cov thermal conductivity tsawg thiab zoo thermal rwb thaiv tsev.

Lub zog ntawm high-strength polypropylene elastic yarn yog thib ob tsuas yog cov nylon, tab sis nws tus nqi tsuas yog 1/3 ntawm cov nylon.Cov ntaub ntawv tsim muaj qhov loj me, ruaj khov tsis kam thiab elasticity, thiab zoo tshuaj stability.Txawm li cas los xij, vim nws tsis zoo thermal stability, insolation kuj thiab yooj yim aging thiab brittle puas, anti-aging agents feem ntau ntxiv rau polypropylene.

4. Kev siv

Kev siv pej xeem: Nws tuaj yeem muab spun ntshiab lossis sib xyaw nrog cov ntaub plaub, paj rwb lossis viscose los ua txhua yam ntawm cov ntaub ntawv khaub ncaws.Nws tuaj yeem siv rau knitting txhua yam ntawm knitwear xws li thom khwm, hnab looj tes, knitwear, knitted ris, phaj ntaub, yoov tshaj cum ntaub, quilt, sov stuffing, ntub ntaub so ntswg, thiab lwm yam.

Cov ntawv thov kev lag luam: ntaub pua plag, nuv ntses nets, canvas, hoses, qhob reinforcement, industrial fabrics, non-woven fabrics, thiab lwm yam xws li ntaub pua plag, industrial lim ntaub, ropes, nuv ntses nets, lub tsev cov ntaub ntawv, roj-absorbing pam vov thiab hniav ntaub, thiab lwm yam. Tsis tas li ntawd, polypropylene zaj duab xis fiber ntau tuaj yeem siv los ua cov khoom ntim. 

5. Qauv

Polypropylene fiber tsis muaj cov tshuaj lom neeg uas tuaj yeem ua ke nrog cov dyes hauv nws cov qauv macromolecular, yog li nws nyuaj rau zas xim.Feem ntau, cov pigment npaj thiab polypropylene polymer yog uniformly tov nyob rau hauv ib tug ntsia hlau extruder los ntawm yaj xim txoj kev, thiab cov xim fiber ntau tau los ntawm yaj spinning muaj xim ceev ceev.Lwm txoj kev yog copolymerization lossis graft copolymerization nrog acrylic acid, acrylonitrile, vinyl pyridine, thiab lwm yam, kom cov pawg polar uas tuaj yeem ua ke nrog cov dyes tau nkag mus rau hauv polymer macromolecules, thiab tom qab ntawd dyed ncaj qha los ntawm cov qauv txheej txheem.Nyob rau hauv cov txheej txheem ntawm polypropylene fiber ntau, nws yog ib qho tsim nyog yuav tau ntxiv ntau yam additives los txhim kho cov dyeability, lub teeb tsis kam thiab nplaim taws.
