Yintoni Unyango Lwangaphambi Kokushwabana Kwelaphu Lesilika?

                                Yintoni Unyango Lwangaphambi Kokushwabana Kwelaphu Lesilika?

Unyango lwangaphambili lwe-shrink yinkqubo esebenzisa iindlela eziphathekayo zokunciphisa i-shrinkage yelaphu emva kokuhlamba, ukunciphisa i-shrinkage jikelele. Ngokomzekelo, i-silika ephindwe kabini i-georgette inezinga eliqhelekileyo lokucutheka kwe-10-15%. Nangona kunjalo, emva kokuncipha kwangaphambili, eli zinga lingancitshiswa libe yi-3-5% kuphela.

• Le nkqubo, eyaziwa ngokuba yi-mechanical pre-shrink finishing, igxile kakhulu ekulawuleni ubude (i-warp) yokuncipha kwelaphu. Ngaphambi kokunciphisa kwangaphambili, ilaphu lesilika linokuba ne-warp shrinkage ye-5% ukuya kwi-15%. Emva kokonyango, umgangatho we-warp shrinkage uhlala unciphisa ukuya kwi-3% ngokwemigangatho yelizwe, okanye i-1% ngokwemigangatho yaseMelika. Umgangatho waseMelika ungqongqo, apho i-1% ilingana ne-3% kwimigangatho yelizwe.
• Amalaphu afana ne-satin ecacileyo, i-satin yolula, kunye ne-chiffon zihlala zinezinga lokushwabana elimalunga ne-5%, ngoko ke ukuba imveliso ayinazo iimfuno ezingqongqo zokucutheka, olu nyango lunokungahoywa ngamanye amaxesha. Nangona kunjalo, kumalaphu afana nesilika ephindwe kabini yegeorgette, igeorgette ephindwe kabini, kunye negeorgette, enemilinganiselo yokucutheka ngaphezulu kwe-10%, ukushwabana kwangaphambili kubalulekile ngaphambi kokusikwa ukunqanda ukushwabana kwasemva kokuveliswa. Enyanisweni, isilika crepe georgette inokuncipha ngaphezu kwama-25%!
• Unyango lwangaphambili luqinisekisa ukuba iingubo ezigqityiweyo zigcina ubukhulu bazo obujoliswe kuzo kwaye zifanelekile emva kokuhlamba, okwenza kube yinyathelo elibalulekileyo ekuveliseni iingubo zesilika.
