Raws li cov khoom siv sib xyaw ua ke sib xyaw ua ke thiab cushioning nrog cov yas ntawm cov ntaub, kev ua haujlwm ntawm daim txhuam cev yog ze rau nws cov khoom tseem ceeb. Los ntawm cov ntaub ntawv muaj pes tsawg leeg pom, daim txhuam cev feem ntau muaj ob qhov tseem ceeb: ib txheej txheej ua npuas ncauj thiab ib daim ntaub nto. Ob qhov no tau ua ke los ntawm cov txheej txheem tshwj xeeb los tsim cov txheej txheem uas muaj ob qho tib si rov qab thiab kev poob siab absorbing peev xwm thaum tswj qhov chaw ruaj khov. Kev nkag siab txog nws cov ntsiab lus tseem ceeb thiab cov yam ntxwv yuav pab kom nkag siab txog nws cov txiaj ntsig kev ua haujlwm thiab kev hloov pauv hauv cov xwm txheej sib txawv.
Cov txheej txheem ua npuas ncauj yog qhov tseem ceeb rau kev ua tiav cushioning thiab elasticity hauv daim txhuam cev. Cov ntaub ntawv tseem ceeb yog polyurethane ua npuas ncauj thiab polyvinyl cawv ua npuas ncauj. Polyurethane ua npuas ncauj yog tsim los ntawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst. Nws muaj peb yam -sib nqus network microporous qauv, thiab nws qhov ceev, qhov pore loj, thiab tus nqi rov qab tuaj yeem tswj tau los ntawm kev kho cov khoom siv raw piv, foaming agent ntau npaum li cas, thiab cov tshuaj tiv thaiv. Tsawg- ntom ntom, loj- pore polyurethane ua npuas ncauj yog lub teeb yuag thiab breathable, haum rau cov khaub ncaws hauv ob sab phlu lossis khau rau lub caij ntuj sov; siab- ntom ntom, me me- pore polyurethane ua npuas ncauj muaj qhov muaj zog resilience thiab kev ua haujlwm siab zoo, thiab feem ntau yog siv rau hauv cov khoom siv tiv thaiv kev ua si, insoles, thiab ntim khoom lag luam - thaj chaw uas yuav tsum muaj cushioning siab. Polyvinyl cawv ua npuas ncauj, raws li ib tug dej{11}}soluble polymer, muaj zoo heev cushioning zog thiab yog biodegradable, ua rau nws lug siv nyob rau hauv kev kho mob hnav khaub ncaws thiab ib puag ncig tus phooj ywg cov khoom nyob rau hauv tsev, qhia txog cov kev taw qhia ntawm daim ntawv thov ntawm cov ntaub ntawv ntsuab.
Qhov kev xaiv ntawm cov ntaub ntaub muaj pes tsawg leeg cuam tshuam ncaj qha rau qhov kev ntxhib los mos, durability, thiab kev ua haujlwm nthuav dav ntawm daim txhuam cev. Cov fibers muaj xws li ob pawg tseem ceeb: ntuj fibers thiab hluavtaws fibers. Paj Rwb, ib tus neeg sawv cev ntawm cov fiber ntau, muaj ntau pawg hydrophilic hauv nws cov qauv molecular, muab cov ntaub mos, tawv nqaij -tus phooj ywg, breathable, thiab noo noo- wicking khoom, ua rau nws haum rau cov khaub ncaws hauv ob sab phlu thiab cov khoom me me uas tuaj rau hauv cov tawv nqaij ncaj qha. Linen fibers, ntawm qhov tod tes, muaj lub zog siab thiab cov khoom siv tshuaj tua kab mob zoo, ua rau lawv tsim nyog rau tsev neeg cushions uas ua haujlwm ntev thiab kev nyiam huv yog qhov tseem ceeb. Ntawm cov tshuaj fibers, polyester (polyester fiber) nthuav tawm zoo heev puas ntsoog, wrinkle tsis kam, thiab cov duab tuav vim nws cov saw molecular thiab siab crystallinity. Nws feem ntau ua ke nrog siab - ua npuas ncauj ntom ntom rau cov ntawv thov xws li cov khau kis las thiab cov ntaub ntawv tiv thaiv kev lag luam uas yuav tsum tau ua kom ntev - lub sij hawm tiv thaiv kev sib txhuam thiab deformation. Nylon (polyamide fiber) paub txog nws lub siab tawv thiab elastic rov qab, ua rau nws haum rau cov khoom siv tiv thaiv iav nrog cov kev xav tau siab rau lub zog tensile thiab kev cuam tshuam. Acrylic fiber ntau (polyacrylonitrile fiber), zoo li cov ntaub plaub, muaj qhov sov so zoo thiab tuaj yeem siv rau lub caij ntuj no khaub ncaws lossis hauv tsev rwb thaiv tsev. Tsis tas li ntawd, los ntawm kev siv cov txuj ci sib xyaw los cuam tshuam cov fibers ntuj thiab tshuaj lom neeg hauv cov kev faib ua feem, ob qho tib si ntawm daim tawv nqaij - kev phooj ywg thiab kav ntev tuaj yeem ua tiav. Piv txwv li, paj rwb-polyester blended fabrics khaws cov breathability thiab noo noo nqus qhov zoo ntawm paj rwb thaum txhim kho wrinkle kuj thiab abrasion tsis kam, nthuav daim ntawv thov ciam teb ntawm daim txhuam cev fabrics.
Dhau li ntawm cov khoom tseem ceeb, kev ua haujlwm ntawm daim txhuam cev yog feem ntau ua tiav los ntawm kev sib ntxiv ntawm cov auxiliaries. Txawm hais tias auxiliaries tsis yog cov khoom tseem ceeb, lawv muaj kev cuam tshuam loj rau nws qhov kev ua tau zoo. Piv txwv li, ntxiv cov tshuaj tua kab mob thaum lub sij hawm ua npuas ncauj synthesis tuaj yeem cuam tshuam cov kab mob kev loj hlob, ua rau nws tsim nyog rau kev kho mob lossis chaw ntub dej; ntxiv cov nplaim hluav taws tuaj yeem txhim kho kev nyab xeeb hluav taws, ua tau raws li cov lus qhia tshwj xeeb rau kev lag luam lossis kev thauj mus los sab hauv; Kev siv cov txheej txheem dej tsis zoo thaum lub sijhawm ua tiav cov ntaub tuaj yeem txhim kho kev ua haujlwm ntawm daim txhuam cev hauv qhov chaw sab nraum zoov lossis qhov chaw ntub dej. Kev tshawb fawb ntawm cov khoom siv ntxiv no tso cai rau daim txhuam cev kom ua tiav kev ua haujlwm ntxiv thaum tswj hwm qhov zoo ntawm nws cov khoom tseem ceeb.
Hauv cov ntsiab lus, cov khoom tseem ceeb ntawm daim txhuam cev yog polyurethane lossis polyvinyl cawv thiab lwm yam khoom siv polymer hauv cov txheej txheem ua npuas dej, thiab cov khoom siv ntuj tsim los yog tshuaj lom neeg hauv cov ntaub. Cov yam ntxwv muaj pes tsawg leeg thiab kev faib ua feem ntawm ob lub ntsiab lus ncaj qha txiav txim siab cov khoom tseem ceeb ntawm daim txhuam cev, xws li ceev, elasticity, breathability, thiab durability. Los ntawm kev tswj cov khoom tseem ceeb thiab lawv cov txheej txheem sib xyaw ua ke, cov khoom siv sponge tau tsim kho kom haum rau cov xwm txheej sib txawv tuaj yeem tsim, muab cov khoom siv daws teeb meem uas ua ke nrog kev nplij siab thiab kev ua haujlwm rau khau, khaub ncaws, khoom vaj khoom tsev, kho mob, thiab kev lag luam.
