1. Kusimba uye elasticity yemafibhi ane hurombo husina kusimba hwedonje hwakaipa kupfuura shinda dzakakura.Zviri nyore kutyora uye kugadzira donje knot mukugadzirwa nekuda kwekugadzirisa maruva ekukungurusa uye kubvisa donje.
Sangano rekutsvagisa machira rakapatsanura chikamu chemhando dzakasiyana dzemafibhi ezvakagadzirwa kuita mapoka matatu, anoti M1R = 0.85, M2R = 0.75, uye M3R = 0.65 yekutenderera bvunzo.Mhedzisiro yebvunzo uye huwandu hwegauze donje mapfundo akanyorwa mutafura sepazasi.

Tafura iri pamusoro apa inoratidza kuti kukura kwakaita chidimbu cheshinda dzisati dzakura mudonje mbishi, ndipo panobva pawedzera pfundo redonje pashinda.
Nemapoka matatu edonje yakarukwa yakarukwa, kunyangwe dambudziko harina kuwanikwa pajira risina chinhu, mapiinzi machena edonje mbishi ane immature fiber content akawanikwa achiwedzerwa zvakanyanya kupfuura mapiinzi machena edonje mbishi ine yakakura mature fiber content.
2. Kunaka uye kukura kwedonje mbishi kunowanzo kuratidzwa neiyo micron kukosha.Izvo zviri nani kukura kwedonje mbishi, kukosha kwemicron yepamusoro, mhando dzedonje dzepakutanga dzakasiyana, uye kukosha kwemicron kwakasiyana.
Iyo donje yakasvibira ine kukura kwakanyanya ine elasticity iri nani uye simba repamusoro, haizobudise chero donje knot mukuruka. Iyo fiber ine yakaderera maturity, nekuda kwehurombo kusimba, uye kuderera kwesimba rimwe chete, mumamiriro ekurova mamwechete, ndiyo nyore kugadzira donje knot uye pfupi fiber.
Kana iyo yakajeka yekotoni inorova kumhanya iri 820 rpm, nekuda kweiyo yakasiyana micron kukosha, iyo donje knot uye pfupi velvet zvakasiyanawo, asi inoenderana yakaderera beater kumhanya, mamiriro acho achavandudzwa, sezvakaratidzwa mutafura.

Tafura iri pamusoro inoratidza kuti mutsauko wefiber fineness uye kukura uye akasiyana micron kukosha kukanganisa pashinda yedonje knot zvirimo zvakare zvakasiyana.

3. Mukusarudza kwekotoni yakasvibirira uye dhizaini yekuchenesa donje uye tekinoroji yemuzinga, kunze kwekureba, zvakasiyana-siyana, cashmere nezvimwe zviratidzo, kunyanya kutariswa kunofanirwa kubhadharwa pakusarudzwa kwekotoni mbishi uye micron kukosha.Kunyanya mukugadzirwa kwedonje reupland uye refu stapled donje, kukosha kwethemicron kunonyanya kukosha, kusarudzwa kwehuwandu hwemakron kukosha kunowanzo 3.8-4.2.Mukugadzira tekinoroji yekuruka, isu tinofanirawo kutarisisa kukura kwekotoni fiber, kuitira kuti tive nechokwadi chekudzikiswa kwekotoni knot uye kuvandudza kunaka kwekuruka, kuruka uye kudhaya zvakatsiga.
