1.Njira Yoyimira

• Chiwerengero cha metric

Nm = l (unit m) / g (gawo g).

• Inch Kuwerengera (NE) kumatanthauza mayadi a thonje 840 olemera 1 mapaundi (453.6 yarn) (1 pabwalo) kutalika.

NE = L (Unit Y) / {g (gawo p) x840)}.

Chiwerengero cha inchi ndi gawo loyenererana ndi muyezo wakale wa National Yarness ya thonje, yomwe yasinthidwa ndi nambala yapadera. Ngati 1 mapaundi a Yarn ali ndi mayadi 60 840 motalika, kukoma bwino ndi mainchesi 60, omwe amatha kulembedwa ngati 60s. Choyimira ndi njira yowerengera inch kuwerengera kwa zingwezo ndizofanana ndi kuchuluka kwa menic.

2.dongosolo lokhazikika

Amatanthauza kulemera kwa kutalika kwa fiber kapena ulusi.

Wocheperako, mtengo wabwino kwambiri. Zigawo zake zimaphatikizapo nambala yapadera (Nteki) ndi Denier (Nden).

• Ntex, kapena Tex, amatanthauza kulemera kwa magalamu a 1000m kutalika kapena ulusi wotchukanso, womwe umadziwikanso kuti nambalayo.

Ntex = 1000g (unit g) / l (unit m)

Kwa ulusi umodzi, nambala ya Tex ikhoza kulembedwa mu mawonekedwe a "18 Tex", zomwe zikutanthauza kuti ulusi ndi mamita 1000 motalika, kulemera kwake ndi 18 magalamu. Chiwerengero cha zingwe ndi zofanana ndi kuchuluka kwa mayanda ochulukitsidwa ndi kuchuluka kwa zingwe. Mwachitsanzo, 18X2 amatanthauza kuti msipu awiri a tex ali ndi zaka 18, ndipo kukoma kwa PL ndi 36 tex. Pamene kuchuluka kwa ulusi umodzi womwe umapangitsa zingwezo ndizosiyana, kuchuluka kwa zingwe ndi kuchuluka kwa kuchuluka kwa ulusi uliwonse.

Kwa ulusi, chiwerengero cha tex ndichachikulu kwambiri, ndipo nthawi zambiri chimafotokozedwa mu Desitex (Ndtex). Desitex (unit Dtex) amatanthauza kulemera kwa magalamu a 10000m kutalika kwa chinyezi.

Ndtex = (10000G × gk) / l = 10 × ntex

• Denier (Nden) ndi Deniers, omwe amatanthauza kulemera kwa magalamu a 9000m kapena ulusi wokhazikika pa chinyezi choyambirira.

Nten = 9000g (unit g) / l (gawo m)

Otsutsa akhoza kufotokozedwa monga: 24 Anier, otsutsa 30 ndi otero. Wotsutsa zingwe amafotokozedwa chimodzimodzi ndi nambala yapadera. Denier nthawi zambiri amagwiritsidwa ntchito kufotokozera za ukoma wa chilengedwe kapena chiberekero cha fiber.

Njira Yapakatikati

Kuwerengera kwa nsalu ndi njira yosonyezera ulusi, nthawi zambiri kumawerengeredwa mu inch (8.5%), ndiye kuti:

Nthawi zambiri, mukamachita nsanje, mawu angapo akatswiri amaphatikizidwa: Kuwerenga, kachulukidwe. Ndiye kodi nsalu yowerengera ndi kachulukidwe imakhudza bwanji mtundu wa nsalu?

Anthu ena atha kukhalabe mu chithunzi. Nkhani yotsatirayi idzafotokoza mwatsatanetsatane.
