1.njira yowonetsera

• Metric count (Nm) imatanthawuza kutalika kwa mita ya ulusi wa gramu (kapena ulusi) pakubwezeretsa chinyezi.

Nm=L (gawo m)/G (gawo g).

• Inchi count (Ne) Amatanthawuza kuchuluka kwa mayadi 840 a thonje wolemera 1 pound (453.6 magalamu) (ulusi waubweya ndi mayadi 560 paundi) (1 yard = 0.9144 mita) utali.

Ne=L(unit y)/{G(unit p)X840)}.

Kuwerengera kwa inchi ndi gawo loyezera lomwe limatchulidwa ndi chikhalidwe chakale cha dziko la makulidwe a thonje la thonje, lomwe lasinthidwa ndi nambala yapadera.Ngati 1 pounds ya ulusi ili ndi mayadi 60 840 kutalika, ulusi wa ulusi ndi 60 inchi, womwe ukhoza kulembedwa ngati 60S.Njira yoyimira ndi yowerengera ya inchi yowerengera ya zingwe ndizofanana ndi kuchuluka kwa ma metric.

2.dongosolo lautali wokhazikika

Zimatanthawuza kulemera kwa utali wina wa ulusi kapena ulusi.

Mtengo wocheperako, ulusiwo umakhala wosalala.Miyezo yake imaphatikizapo nambala yapadera (Ntex) ndi denier (Nden).

• Ntex, kapena tex, imatanthawuza kulemera kwa magalamu a ulusi wautali wa 1000m kapena ulusi pakupezanso chinyezi, komwe kumadziwikanso kuti nambala.

Ntex=1000G (unit g)/L (unit m)

Kwa ulusi umodzi, nambala ya tex ikhoza kulembedwa ngati "18 tex", zomwe zikutanthauza kuti ulusi ukakhala wautali mamita 1000, kulemera kwake ndi 18 magalamu.Chiwerengero cha zingwe ndi chofanana ndi chiwerengero cha ulusi umodzi wochulukitsa ndi chiwerengero cha zingwe.Mwachitsanzo, 18X2 amatanthauza kuti ulusi umodzi wa 18 tex ndi plied, ndipo ply fineness ndi 36 tex.Pamene chiwerengero cha ulusi umodzi umene umapanga zingwezo ndi wosiyana, chiwerengero cha nsonga ndicho chiŵerengero cha manambala a ulusi uliwonse.

Kwa ulusi, nambala ya tex ndi yayikulu kwambiri, ndipo nthawi zambiri imawonetsedwa mu decitex (Ndtex).Decitex (unit dtex) imatanthawuza kulemera kwa magalamu a ulusi wotalika 10000m pakubwezeretsa chinyezi.

Ndtex=(10000G×Gk)/L=10×Ntex

• Denier (Nden) ndi denier, zomwe zikutanthauza kulemera kwa magalamu a ulusi wautali wa 9000m kapena ulusi pakubwezeretsanso chinyezi.

Nden=9000G (unit g)/L (unit m)

Wotsutsa akhoza kufotokozedwa motere: 24 wotsutsa, 30 wotsutsa ndi zina zotero.Wotsutsa wa zingwe amasonyezedwa mofanana ndi nambala yapadera.Denier nthawi zambiri amagwiritsidwa ntchito kufotokoza ulusi wa silika wachilengedwe kapena ulusi wamankhwala.

3.kuyimira njira

Kuwerengera kwa nsalu ndi njira yowonetsera ulusi, yomwe nthawi zambiri imawonetsedwa ngati inchi count (S) mu "custom weight system" (njira yowerengera iyi imagawidwa mu chiwerengero cha metric ndi inchi count), ndiko kuti: mu boma Pansi pa chinyezi. kupezanso (8.5%), chiwerengero cha skein chokhala ndi kutalika kwa mayadi 840 pa skein mu ulusi wopota wolemera paundi imodzi ndi chiwerengero cha mawerengedwe.

Nthawi zambiri, pochita bizinesi ya nsalu, mawu angapo akatswiri nthawi zambiri amakhudzidwa: kuwerengera, kachulukidwe.Ndiye kodi kuwerengera kwa nsalu ndi kachulukidwe kake kumakhudza bwanji mtundu wa nsalu?

Anthu ena angakhale akadali m’chizungulire.Nkhani yotsatirayi ifotokoza mwatsatanetsatane.
