Xov xov twist paub

Cov xov paj: Ib lo lus dav dav rau cov xov paj thiab xov, nyias, mos, txuas ntxiv ntev sawb ua los ntawm textile fibers, nrog rau ib qho xov paj thiab cov hlua.

Tib yarn: Nws yog ua tiav los ntawm spinning luv fibers, kom lub luv fibers los yog filaments yog teem nyob rau hauv lub axial kev taw qhia thiab twisted.

Stranded yarn: Nws yog ua los ntawm ob los yog ntau tshaj ib yarns ua ke thiab twisted, thiab nws lub zog thiab hnav tsis kam yog zoo dua li ib yarns.

Dab tsi yog twisting?

Yog hais tias ib qho kawg ntawm lub whisker yog tuav thiab lwm qhov kawg yog tig ib ncig, ib tug xov paj yog tsim, ib tug txheej txheem hu ua twisting.

Rau luv fibers, twisting yog ib qho tsim nyog txhais tau tias ua fiber ntau strips rau hauv yarns. Ua ntej twisting, nws yog feem ntau tsim nyog rau condense xoob fibers rau hauv fiber ntau strips. Tom qab twisting, cov txheej fibers ntawm cov fibers yog extruded mus rau lub puab txheej los tsim centripetal siab. Yog li, cov plaub hau tau txais kev sib txhuam raws qhov ntev ntawm cov fiber.

Rau filament yarns thiab strands, twisting tuaj yeem tsim cov qauv compact uas tsis yooj yim puas los ntawm sab nraud quab yuam, thiab twisting tuaj yeem tsim cov xov paj zoo nkauj thiab cov xov paj zoo nkauj. Tus nqi ntawm kev sib tw thiab cov kev taw qhia ntawm twist tsis tsuas yog cuam tshuam rau kev xav thiab cov tsos ntawm cov ntaub, tab sis kuj cuam tshuam rau qhov zoo ntawm cov ntaub.

Tom qab lub sliver yog twisted, cov txheej fibers ntawm lub sliver yog twisted thiab twisted, lub fibers yog twisted thiab deformed, thiab cov sliver yog nruj nreem interlocked, uas hloov cov structural puab thiab txhua yam thiab lub cev zog ntawm lub fibers.

Thaum muaj lub kaum sab xis nyob rau hauv lub sliver, cov fibers muaj centripetal siab ntawm lub sliver, thiab qhov loj ntawm lub kaum sab xis, lub siab centripetal ntau dua. Vim yog lub centripetal siab, cov txheej txheej txheej fibers yog squeezed mus rau lub puab txheej, uas ua rau kom lub nruj ntawm lub sliver thiab kev sib txhuam ntawm cov fibers, yog li hloov cov qauv thiab lub cev thiab txhua yam khoom ntawm lub sliver, uas yog twisting. Lub essence ntawm yarn.
