Cov yam ntxwv cuam tshuam rau lub zog thiab elongation ntawm Staple Fiber yarn

Cov yam ntxwv cuam tshuam rau lub zog thiab elongation ntawmxov pajFeem ntau yog ob yam, raws li cov cuab yeej fiber ntau thiab cov xov paj. Ntawm, lub zog thiab elongation ntawm cov xov paj sib xyaw kuj zoo sib xws rau cov cuab yeej sib txawv ntawm cov khoom sib xyaw fiber ntau thiab sib xyaw ua ke.

Cov khoom ntawm Fiber

1.Length thiab linear ceev ntawm fiber ntau:
Thaum lub fiber ntev ntev thiab cov fiber ntau zoo, kev sib txhuam ntawm cov fibers hauv cov xov paj yog loj, thiab nws tsis yooj yim rau plam, yog li lub zog ntawm cov xov paj yog siab.
Thaum cov fiber ntev uniformity zoo thiab cov fiber ntau zoo thiab txawm, cov xov paj strips txawm thiab cov nplhaib tsis muaj zog yog tsawg thiab tsis tseem ceeb, uas yog qhov zoo rau kev txhim kho cov xov paj.
2. Lub zog ntawm fiber ntau:
Yog tias lub zog thiab elongation ntawm fiber ntau muaj zog, lub zog thiab elongation ntawm cov xov paj muaj zog dua.
3.Ntog kev sib txhuam khoom ntawm fiber ntau:
Thaum qhov kev sib txhuam ntawm cov khoom ntawm fiber ntau nce, zawv zawg tiv thaiv ntawm fibers yuav nce ntxiv thiab qhov ntev yuav txo qis, yog li kev swb.fibersyuav txo qis thiab lub zog ntawm cov xov paj yuav nce. Tsis tas li ntawd txhawm rau txhim kho tus lej crimp ntawm fiber ntau yuav ua rau kom zawv zawg tsis kam ntawm fibers.

Fiber Structure

1.Twist ntawm xov paj
Thaum cov twist coefficient nce, kev sib txhuam ntawm cov ntoo fibers nce, yog li nws tsis yooj yim rau plam, uas ua rau cov xov paj muaj zog. Thaum cov twist coefficient nce, cov fibers yog tilting ntau thiab ntau dua, cov khoom siv zog ntawm fiber ntau hauv cov xov paj axial kev taw qhia yuav txo. Tsis tas li qhov nce ntawm cov xov paj txoj kab uas hla thaum lub fiber yog qaij yuav txo lub zog ntawm cov xov paj.
2. Plying
Kev sib xyaw ntawm ib lub xov paj ua rau cov strips ntawm plyyarn txawm. Tsis tas li ntawd, tib lub xov tooj sib cuag nrog ib leeg, uas ua rau lub zog cohesive ntawm cov fibers sab nraud ntawm ib qho xov paj nce. Lub zog ntawm plyyarn yog loj dua qhov sib npaug ntawm ib lub zog ntawm cov xov paj.
3.Qhov kev npaj ntawm fibers nyob rau hauv staple yarn
Lub zog ntawm rotor xov paj yog qis dua li ntawm cov xov paj.
4.Bulked xov paj
Tensile tawg lub zog ntawm bulked yarn yog me dua li cov xov paj ib txwm. Thiab qhov elongation ntawm tawg ntawm bulked yarn yog loj dua.
5.extured yarn thiab stretch yarn
