Litšenyehelo tsa Lesela Raw Material
Palo ea Litšenyehelo tsa Warp Raw=Warp Density x Width x Warp Khoele (D) / 9000 x (1 + Weaving Shrinkage le Process Shrinkage Rate) x ({3}} Raw Material Loss Rate) x Theko ea Raw Material Unit
Palo ea Litšenyehelo tsa Weft Raw=Bophahamo ba Bophahamo ba Bophahamo x Bophara x Khoele ea Weft (D) / 9000 x (1 + Sekhahla sa Ho Oha le Sekhahla sa Ts'ebetso) x ({3}} Sekhahla sa Tahlehelo ea Maemo) x Theko ea Raw Material Unit
Haeba likhoele tse tšekaletseng li sebelisa likhoele tse telele (D), lipalo li ka etsoa joalo ka ha holimo. Haeba likhoele tsa weft li sebelisa likhoele tse khutšoane (S), joale qala ka ho kopanya lihlopha.
D = 5315/S
Ho na le mefuta e 'meli ea lisebelisoa tse tala bakeng sa likhoele tsa weft. U hloka ho tseba tlhophiso ea lisebelisoa tse peli tse tala. Ebe u bala tšebeliso ea khoele bakeng sa thepa e 'ngoe le e' ngoe e tala ho latela karo-karolelano.
Mohlala, haeba tlhophiso ea khoele ea weft e le A5B3A6B4, joale ha ho baloa khoele ea weft bakeng sa weft A, letsoalo la weft le baloa joalo ka boima ba lesela le bohlooho x 11/18. Tse ling... Bala ka ho sebelisa foromo e ka holimo:
Ha u bala boima ba "weft density" ea B{{0}weft raw material, sebelisa greige fabric weft density x 7/18. Bakeng sa lisebelisoa tse ling, bala ka mokhoa o ka holimo. Ho honyela ha ho loha le ho honyela ha tšebetso ho baloa ka tsela e latelang: 5%~30% bakeng sa likhoele tsa lik'hemik'hale le 8~12% bakeng sa-cotton kaofela. Coefficient ena e lekana ka ho toba le ho eketseha ha sekhahla sa weft le ho sotha ha lesela, 'me ho fapana le ho eketseha ha bolelele ba float ea warp. Tahlehelo ea thepa e tala e baloa ka tsela e latelang: 4% ~ 5% bakeng sa warp e tšoanang le weft, le 6 ~ 8% bakeng sa warp e sa lumellaneng le weft.
Ka mor'a moo, bala litšenyehelo tsohle tsa lesela la greige: (warp + weft) litšenyehelo tsa thepa e tala + litšenyehelo tsa ho loha. Litšenyehelo tsa ho loha hangata li khethoa ke boima ba lesela la greige, ka mechini ea jete ea metsi e fihlang ho 4 ~ 8 points/weft. Sena se amana le sebaka sa sebaka sa leloala la ho loha le bothata ba ho sebetsa ha sehlahisoa.
Litjeo tsa lesela le felileng=litjeo tsa lesela la greige x sekhahla sa ho daea se fokotsehang + litšenyehelo tsa ho daea + thepa, ho paka, le litšenyehelo tse ling tse fapaneng.
Tlhokomeliso: Density e bolela palo ea likhoele ka sentimetara.
