• ʻO ka helu metric (Nm) e pili ana i ka lōʻihi o nā mika o ka gram o ka yarn (a i ʻole ka fiber) i ka loaʻa hou ʻana o ka wai.

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

• Helu iniha (Ne) E pili ana ia i ka nui o 840 iwilei pulupulu nona ke kaumaha 1 paona (453.6 kalama) (560 iwilei no ka paona) (1 iwilei = 0.9144 mika) ka loa.

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

ʻO ka helu ʻīniha ka ʻāpana ana i hōʻike ʻia e ke kūlana aupuni kahiko no ka mānoanoa o ka ʻili pulupulu, i pani ʻia e ka helu kūikawā. Inā he 60 840 iwilei ka lōʻihi o 1 paona ʻili, he 60 ʻīniha ka maikaʻi o ka ʻili, hiki ke helu ʻia he 60S. ʻO ke ʻano hōʻike a me ka helu ʻana o ka helu ʻīniha o nā kaula e like me ka helu metric.

2.ʻōnaehana lōʻihi paʻa

E pili ana i ke kaumaha o kekahi lōʻihi o ka fiber a i ʻole ka wili.

ʻO ka liʻiliʻi o ka waiwai, ʻoi aku ka maikaʻi o ke kaula. ʻO kāna mau ana ana he helu kūikawā (Ntex) a me ka denier (Nden).

• ʻO Ntex, a i ʻole tex, e pili ana i ke paona i loko o ka grams o kahi fiber 1000m lōʻihi a i ʻole wili i ka loaʻa hou ʻana o ka makū, ʻike ʻia ʻo ka helu.

Ntex=1000G (ʻāpana g)/L (ʻāpana m)

No ka wili hoʻokahi, hiki ke kākau ʻia ka helu tex ma ke ʻano o "18 tex", ʻo ia hoʻi, ke 1000 mika ka lōʻihi o ke kaula, ʻo 18 grams kona kaumaha. Ua like ka helu o nā kaula me ka helu o nā kaula hoʻokahi i hoʻonui ʻia me ka helu o nā kaula. No ka la'ana, 18X2, 'o ia ho'i, 'elua wili ho'okahi o 18 tex i plied, a 'o ka wili o ka ply he 36 tex. Ke ʻokoʻa ka helu o nā kaula hoʻokahi i hana i nā kaula, ʻo ka helu o nā kaula ka huina o nā helu o kēlā me kēia kaula.

No nā fiber, ʻoi aku ka nui o ka helu o ka tex, a ua hōʻike pinepine ʻia i ka decitex (Ndtex). ʻO ka decitex (unit dtex) e pili ana i ke kaumaha o ka 10000m ka lōʻihi o ka fiber i ka loaʻa hou ʻana o ka wai.

Ndtex=(10000G×Gk)/L=10×Ntex

• ʻO Denier (Nden) ka denier, e pili ana i ke kaumaha o ka 9000m ka lōʻihi o nā fibers a i ʻole nā ​​yarns i ka manawa e hoʻihoʻi hou ʻia ai ka wai.

Nden=9000G (ʻāpana g)/L (ʻāpana m)

Hiki ke hōʻike ʻia ʻo Denier e like me: 24 denier, 30 denier a pēlā aku. Hōʻike ʻia ka denier o nā kaula e like me ka helu kūikawā. Hoʻohana pinepine ʻia ʻo Denier e hōʻike i ka maikaʻi o ka fiber silk maoli a i ʻole ka filament fiber kemikal.

3.representing method

ʻO ka helu lole he ala ia e hōʻike ai i ka wili, i hōʻike pinepine ʻia e like me ka helu ʻīniha (S) ma ka "pūnaewele kaumaha maʻamau" (ua māhele ʻia kēia ʻano helu i ka helu metric a me ka helu ʻīniha), ʻo ia hoʻi: ma ke kūlana ma lalo o ke kūlana o ka wai loaʻa hou (8.5%), ʻo ka helu o nā skeins me ka lōʻihi o 840 iwilei no kēlā me kēia skein i loko o ka wili wili e kaumaha ana i hoʻokahi paona ka helu o nā helu.

ʻO ka maʻamau, i ka wā e hana ai i ka ʻoihana lole, pili pinepine ʻia kekahi mau huaʻōlelo ʻoihana: helu, density. No laila he aha ka hopena o ka helu a me ka nui o ka lole i ka maikaʻi o ka lole?

Aia paha kekahi poʻe i loko o ka puzzle.
