Dab tsi yog lub ntsiab lus tseeb ntawm 40s / 2 thiab Tex29.5 ntawm xaws xov?
Thaum peb piav qhia txog cov xov paj / xov, muaj 3 qhov ntsuas qhov yooj yim / cov ntaub ntawv. Thawj yog qhov muaj pes tsawg leeg ntawm cov xov paj / xov, piv txwv li, 100% paj rwb, 100% polyester, T / C (paj rwb ntxiv rau polyester), thiab lwm yam. Qhov thib ob yog qhov loj / tuab. Feem ntau muaj ob txoj hauv kev siv, imperial thiab metric. Piv txwv li, 40s yog ib qho imperial system, peb tuaj yeem sau nws li Ne 40, ib txwm peb sau nws li 40s, 20s, 30s, 10s, 7s hauv kev lag luam textile. Qhov thib peb yog txoj kev spinning, xws li OE (Qhib-kawg), OA (Nplhaib spinning), Siro, slub, thiab lwm yam.
Cia peb saib ob qho piv txwv tiav:
100% polyester 40s / 2 spun xov. Cov muaj pes tsawg leeg yog 100 feem pua polyester, 40s=Ne 40, cov xov thickness / loj yog 40s (imperial system), Tex 29.5 (metric system), /2 txhais tau tias 2 yarns / xov, 2 40s ob twisted yarns / xov.
100% paj rwb OE 10s. 100% paj rwb --- muaj pes tsawg leeg, OE --- txoj kev spinning, 10s --- xov paj loj/thickness.
Yuav ua li cas mus Hloov Nees rau Tex? Nws muaj ib tug formula ua nws!
Yog hais tias cov hluavtaws yog 100 feem pua polyester lossis lwm cov khoom siv hluavtaws, cov mis yog: Tex=590.5÷Ne. Piv txwv li, 100 feem pua polyester 40s / 2 xov paj---Ne tooj, 590.5÷40/2=590.5÷40 ×2=29.5, yog li Ne 40s/2=Tex 29.5 Nws
Yog hais tias nws yog compounded li 100 feem pua ntawm cov paj rwb los yog lwm yam ntuj fibers, lub laij lej formula yog: Tex=583.1÷Ne. Piv txwv li, 100% paj rwb OE 10s---Ne tooj, 583.1÷10=58.3, ces Ne 10=Tex 58.3
Yog tias qhov sib xyaw ua ke yog cov fibers sib xyaw, cov qauv yog: Tex =588÷Ne. Piv txwv li, 80% paj rwb 20% polyester T/C40s/2---Ne tooj, 588÷40/2=588÷40 ×2=29.4, yog li T/C Ne40s/{{12 }}Tex 29.5
Cov ntsiab lus tseeb ntawm Tex 29.5. Nws txhais tau hais tias qhov hnyav ntawm 1000 meters ntawm cov xov paj / xov yog 29.5g raws li kev lag luam ya raws rov qab.
