Cov khoom siv tsis-woven polyester

Polyester spunbond non-woven npuag muaj lub zog siab, zoo kub tsis kam (tuaj yeem siv tau ntev hauv 150 ℃ ib puag ncig), kev laus ua haujlwm, UV tsis kam, siab elongation, zoo stability thiab breathability, corrosion kuj, suab rwb thaiv tsev, npauj tsis kam, thiab tsis muaj tshuaj lom.

Cov yam ntxwv ntawm raw khoom

1. Polyester fibers muaj zoo wrinkle kuj, elasticity, thiab seem stability, raws li zoo raws li zoo hluav taws xob rwb thaiv tsev zog. Lawv tiv taus tshav ntuj, kev sib txhuam, pwm, thiab lwj. Lawv kuj muaj kev ua haujlwm zoo rau cov tshuaj reagents thiab tuaj yeem tiv taus cov kua qaub thiab alkalis tsis muaj zog.

2. Nyob rau hauv chav tsev kub, nws muaj ib tug tej yam muaj peev xwm tiv taus dilute thiab muaj zog acids, tab sis tsis zoo kuj muaj zog alkalinity.

3. Cov dyeing kev ua tau zoo ntawm polyester fibers tsis zoo, thiab lawv feem ntau yuav tsum tau dyed nrog dispersed dyes nyob rau hauv high kub los yog nyob rau hauv lub xub ntiag ntawm cov cab kuj.

Kev siv ntawm polyester non-woven npuag

1. Siv rau sab hauv tsev kho kom zoo nkauj, ntaub pua plag hauv paus ntaub, kev lag luam tshuaj ntaub, fluff, hauv ob sab phlu, thiab lwm yam.

2. Siv rau kev tsim kho, ru tsev waterproofing pab raws li ib tug hauv paus ntaub, nrog xuab zeb, xis mas, thiab lwm yam rau nws los tiv thaiv cov xuab zeb to.

3. Siv hauv kev tsim kho, nws yog ib qho kev ntsuas los tiv thaiv cov kab nrib pleb.

4. Raws li kev laus thiab kub ua hauj lwm yam ntxwv ntawm spunbond non-woven fabrics, lawv yog dav siv nyob rau hauv tsev textiles, composite cov ntaub ntawv, lub nra, thiab lwm yam. High kub hloov printing yog siv los tsim high-end thiab pheej yig fabrics; Thiab vim nws aging kuj; Muaj kev lees paub los ntawm cov neeg siv khoom.

Kev ua lag luam rau polyester spunbond non-woven npuag

Daim ntawv thov ntawm geotextiles nyob rau txawv teb chaws pib thaum ntxov li 1960s. Tebchaws Asmeskas yog lub tebchaws uas muaj kev noj ntau tshaj plaws ntawm geotextiles hauv ntiaj teb. Nyob rau hauv thaum ntxov 1990s, nws cov kev siv txhua xyoo yog tshaj 300 lab square meters, thiab nyob rau hauv xyoo tas los no, nws siv tau mus txog 700 lab square meters. Geotextiles hauv Tebchaws Europe thiab Nyij Pooj kuj tau ntsib txoj kev loj hlob sai, nrog kev siv txhua xyoo ntawm thaj tsam 400 lab square meters hauv xyoo tas los no. Ntawm lawv, spunbond nonwoven fabrics suav txog li 60% ntawm nonwoven geotextiles; Tom qab nruab nrab-1990s, Nyiv pom muaj kev nce ntxiv hauv kev siv geotextiles. Ntawm cov Japanese nonwoven geotextiles, kev siv spunbond txoj kev yog qhov loj tshaj plaws, suav txog li 60% ntawm tag nrho cov nyiaj ntawm nonwoven geotextiles, thiab feem ntau yog PET spunbond ntaub.

Geotextile nyob rau hauv peb lub teb chaws pib thaum ntxov 1980s, tab sis tus nqi siv tsawg heev thaum lub sij hawm ntawd, thiab nws tsuas yog ib daim ntawv thov kev sim. Nws tsis yog txog thaum xyoo 1998 dej nyab loj heev uas tsoomfwv tau saib xyuas nws, thiab lub tuam tsev tsim kho tau suav nrog kev siv cov geotextiles hauv cov qauv tsim thiab tsim cov qauv tsim hauv lub tebchaws uas geotextiles tau txais kev saib xyuas thiab kev loj hlob. Tam sim no, kev siv geotextiles hauv Suav teb tau tshaj 300 lab square metres, thiab cov khoom siv tsis-woven geotextiles suav txog li 40% ntawm tag nrho. Tuam Tshoj txoj kev tsim vaj tsev engineering muaj kev lag luam loj loj, uas tsis muaj tsawg dua qhov kev siv tam sim no ntawm 700-800 lab square meters hauv Tebchaws Meskas. Cov kws tshaj lij kwv yees tias Tuam Tshoj cov geotextiles yuav loj hlob ntxiv rau ob tus lej hauv 15 xyoo tom ntej, nrog PET spunbond filament geotextiles qhia qhov kev loj hlob sai tshaj plaws.
