Raw Dawb Paj Rwb Xov Paj 30s

30- suav cov paj rwb dawb huv yog hais txog cov xov paj ib leeg ua los ntawm cov paj rwb tshiab uas tau sau tshiab, los ntawm cov txheej txheem xws li carding → combing → semi-combing → plaiting → coarse yarn → fine yarn (ring spinning or close spinning) → twisting and winding. Nws yog uncolored los yog bleached.

Txoj kev spinning
Carding: Qhib cov paj rwb, sib tov nws, thiab tshem tawm cov impurities (hlau, nplooj khib nyiab, paj rwb plhaub), ua rau cov paj rwb yob.
Carding: Combing los ua cov xov paj raw, tshem tawm cov impurities ntxiv, nrog cov paj rwb tsawg dua los yog sib npaug li 80 ib gram (ua ntej zoo combing).
Fine combing (tus qauv rau Ne 30): Lub tshuab zoo combing tshem tawm cov fibers luv (< 16 mm) by 15%–20%, reducing cotton knots to ≤ 20 per gram, significantly improving yarn uniformity. For yarn counts above 30, fine combing is mandatory; otherwise, the strength will be insufficient, there will be excessive fuzz, and the dyeing will be uneven.
Kev xaiv: 1-2 hla kev xaiv los txhim kho qhov sib xws ntawm cov ntu ntev hauv cov xov paj.
Winding: Stretching rau cov xov paj tuab nrog me ntsis twist.
Xov paj spinning (ntiv nplhaib spinning los yog compact spinning):
Nplhaib spinning: Cov txheej txheem ib txwm muaj, nrog cov qauv ntawm cov xov paj fluffy, muag muag, haum rau knitting thiab weaving. Ne 30 nplhaib spinning yields kwv yees li 15-20 meters ib feeb.
Compact spinning: Raws li lub nplhaib spinning, ntxiv qhov tsis zoo ntawm kev sib sau ua ke, txo fuzz los ntawm 50% -70%, nce lub zog los ntawm 5% -10%, haum rau siab -knitting kawg (txo cov weaving so) thiab cov ntaub du. Compact spinning Ne 30 yog qhov siab -kawg tsim qauv qauv.
Winding: Tsis siv neeg winding tshuab (Murata/Savi) tshem tawm qhov tsis xws luag (electrostatic tu), winding rau hauv raj xov paj (1.2-2.5 kg ib lub raj).
Ncej -kev ua haujlwm (xov paj dawb):
Qhov no dawb: Ncaj nraim winding, khaws cia paj rwb ciab, haum rau tom qab dyeing los yog bleaching.
Bleaching: Hydrogen peroxide bleaching (scouring + bleaching), whiteness Ntau dua los yog sib npaug li 85% ISO, pH nruab nrab, tshem tawm cov quav ciab thiab impurities, haum rau ncaj qha ua dawb puag ntaub lossis lub teeb - xim luam ntawv.

Uniform yarn linear density with exceptional coefficient of variation (CV%): Rau combed Ne 30 ring -spun yarn, CV% 11% mus rau 13%, whereas USTER benchmark data qhia txog kev lag luam dav dav ntawm 5% -25%. Tight-spinning thev naus laus zis ntxiv txo CV% los ntawm 0.5–1.0 feem pua ​​​​cov ntsiab lus. Npuag weaving nthuav tawm cov nqi qis qis (tsawg dua los yog sib npaug li 30 kawg ntawm 100 looms ib teev), ua rau muaj kev ua haujlwm siab thiab ua haujlwm du, tsis xws luag -dawb ntaub.
Lub zog tensile siab: Ib leeg- xov tenacity ranges ntawm 250 mus rau 350 cN-nyob ntawm qib paj rwb fiber ntau thiab twist qib-nrog elongation ntawm so ntawm 5%–7%, siab txaus siab rau cov neeg kho tshuab xav tau ntawm siab -kev ceev weaving ntawm projectile thiab cua 8 pm{8pm.

Txo cov plaub hau: Tight-spun yarn ua tiav H-tus nqi Tsawg dua lossis sib npaug rau 3.0 (vs. Tsawg dua lossis sib npaug li 4.5 rau cov nplhaib sib xyaw ua ke-spun yarn), ua kom muaj txiaj ntsig zoo dua rau siab - ntom ntom weaves thiab refined fabric aesthetics
Tswj whiteness profile: Ib txwm tshwm sim whiteness yog mos thiab txawm; bleached whiteness qhia kev ruaj ntseg zoo (Ntau dua lossis sib npaug ntawm 85% ISO brightness), ua tiav yam tsis muaj qhov muag pom kev ci ntsa iab. Oeko-Tex Standard 100 daim ntawv pov thawj muaj nyob rau ntawm qhov kev thov- ua cov xov paj tsim nyog rau kev kho mob textiles thiab khaub ncaws me nyuam mos.
