Injongo yokucutheka kwangaphambili kunye nolungiselelo

    Injongo yokugqiba ilaphu kukucutheka kwangaphambili kukucutha ilaphu ukuya kumlinganiselo othile kwi-warp kunye nezalathiso ze-weft, ukuze kuncitshiswe izinga lokucutheka kwemveliso yokugqibela kunye nokuhlangabezana neemfuno zomgangatho wokulungiswa kwempahla.

    Ngexesha lenkqubo yokudaya kunye nokugqiba, ilaphu liphantsi koxinzelelo kwicala le-warp, okukhokelela ekunciphiseni komphakamo we-wave bending wave kunye nokuvela kobude. Xa amalaphu e-hydrophilic fayibha emanziswe kwaye afakwe emanzini, iintsinga ziyadumba, kwaye iidayamitha ze-warp kunye ne-weft yarns zinyuka, okukhokelela ekwandeni kokuphakama kwamaza okugoba komsonto wokuluka, ukuncipha kobude belaphu, kunye nokwakheka kokushwabana. Ipesenti yokucutha ubude xa kuthelekiswa nobude bokuqala kuthiwa yireyithi yokucutheka.

    Inkqubo yokugqiba yokunciphisa i-shrinkage yamalaphu emva kokuntywiliselwa emanzini usebenzisa iindlela zomzimba, ezaziwa ngokuba yi-mechanical pre shrinkage finishing. Mechanical preshrinking kukumanzisa ilaphu ngokutshiza umphunga okanye isitshizi, uze usebenzise i-longitudinal mechanical extrusion ukwandisa ubude be-buckling wave, kwaye emva koko ukoma okukhululekile. Izinga lokushwabana kwelaphu lomqhaphu elishwabeneyo langaphambili lingancitshiswa libe ngaphantsi kwe-1%, kwaye ngenxa yokuxinana kunye nokuhlikihlwa phakathi kwemisonto kunye nemisonto, ukuthamba kokuziva kwelaphu nako kuya kuphuculwa.
