Nylon Kub Melt Xov Paj yog lwm txoj hauv kev zoo rau cov nplaum nplaum, cov kuab tshuaj, thiab hmoov. Nws cov khoom tshwj xeeb tso cai rau cov khoom siv huv huv thiab txo qis cov nqi tsim khoom. Ntau daim ntawv thov tib yam uas siv cov nplaum nplaum kuj tuaj yeem ua nrog Nylon Yarn.
Cov khoom ntawm Nylon kub yaj yarn sib txawv heev, nyob ntawm nws daim ntawv. Feem ntau, cov thermoplastic no yog amorphous saum nws qhov kub thiab txias (Tm) thiab crystalline hauv qab nws. Cov cheeb tsam amorphous pab txhawb lub zog thiab elasticity. Cov pawg polar amide tau txuas nrog ntau cov hydrogen bonds ntawm cov kab uas nyob ib sab. Cov amide bonds yog trans thiab tsis tu ncua, thiab lawv tsim ntau chains nyob rau hauv txhua strand.
Cov tshuaj tiv thaiv uas ua rau Nylon kub yaj xov paj yog hu ua polycondensation. Nylon yog ib qho ntawm cov hluavtaws fiber ntau ruaj khov. Nylon yog kaum lub sij hawm ntau abrasion-resistant dua lwm cov fibers thiab nees nkaum zaug muaj zog dua ntaub plaub. Nws tseem tuaj yeem ncab tom qab nws txias, txhim kho nws lub zog thiab elasticity. Nylon kuj zoo ntawm kev tawm tsam lom lom. Nws yog dav siv hauv khaub ncaws thiab khoom vaj khoom tsev. Nws kuj tseem siv rau hauv cov log tsheb, xaws xov, ntaub pua plag, thiab upholstery.
Tensile lub zog yog qhov qhia tau zoo ntawm cov xov paj tenacity. Txawm li cas los xij, qhov degree ntawm elongation tuaj yeem sib txawv nrog qhov kub thiab txias. Cov xov paj hnub nyoog ntawm 140 thiab 160 degC pom cov yam ntxwv zoo sib xws.
Nylon kub yaj yarn yog cov thermoplastic fiber uas muaj cov ntsiab lus melting tsawg. Nws softens mus rau ib tug viscous kua thaum rhuab thiab solidifies thaum txias. Nws feem ntau ua ke nrog lwm cov fibers thiab knitted los yog woven rau hauv cov khoom uas yuav tsum tau thermal bonded fibers. Qhov qis melting point ntawm cov xov paj ua rau nws muaj fiber ntau tshwj xeeb nrog ntau yam kev siv.
Kev siv cov nylon kub yaj xov paj muaj xws li ntaub, textiles, thiab khau. Qhov qis melting point ua rau nws muaj kev nyab xeeb thiab ib puag ncig tus phooj ywg khoom. Nws tseem muaj ntxhiab tsw thiab tsis muaj tshuaj lom. Nws yog ib qho kev xaiv zoo tshaj plaws rau textiles, vim nws muaj qhov siab tshaj plaws kev puas tsuaj ntawm txhua hom fiber ntau.
Nylon xov thiab xov paj ua los ntawm nws yooj yim rau dye dua polyester. Txawm li cas los xij, Nylon xov yog qhov cuam tshuam rau yellowing dua polyester. Nylon yuav ploj mus yooj yim dua yog tias qhov kub siab tshaj 1500 degree. Piv rau polyester, Nylon yog kim dua los siv dua. Txawm li cas los xij, nws tsis tawg rau hauv cov ntaub ntawv tshuaj lom thaum yaj, ua rau nws yog qhov kev xaiv zoo rau ntau yam kev siv.
