Abstract

Prispevek obravnava rezultate optimiranja zamreženja tkanin iz močno vite viskozne preje z brezformaldehidnim reagentom. Proučevali smo vpliv koncentracije brezformaldehidnega reagenta za zamreženje, katalizatorja in neionogenega sredstva za mehčanje na nekatere uporabne lastnosti apretirane viskozne preje. Spremljali smo naslednje veličine: stopnjo nabrekanja viskoznih vlaken, barve razlike, pretržno silo, pretržni raztezek in kot razgubanja. Z uporabo brezformaldehidnega reagenta za zamreženje smo dosegli znižanje stopnje nabrekanja viskoznih vlaken za 51,1 do 92,4 %, povečanje kota razgubanja za 60 do 145%, zmanjšanje pretržne sile za 49% do 65% in pretržnega raztezka za 31,6 do 37,6%. Postopek zamreženja ne povzroča zaznavnik barvnih razlik in obarvanih tkanin.

Secondary title: Statistical desgning of finishing process for viscose fabrics made from hard twisted yarn - Part 1: Finishing with non-fomaldehyde reagents
Secondary abstract: The paper presents the results of optimizing cross-linking of fabrics made from highly twisted viscose yarn by using the nonformaldehyde reagents. The influence of the crosslinking reagent concentration, catalyst and nonionogenic softener on some applicability properties of the finished viscose fabric was investigated. The following parameters were monitored: the degree of swelling of viscose fibres, elongation at break and crease recovery angle, as well as the influence of the finishing process on the colour of viscose fabrics made from highly twisted yarn. By using the cross-linking non-formaldehyde reagent the degree of swelling of viscose fibres decreased by 51.1 - 92.4%, the crease recovery angle increased by 65 - 145%, the breaking force decreased by 49 - 65%, and the elongation at break decreased by 31.6 - 37.6 %. The crosslinking process did not cause any noticeable colour deviations on the dyed fabric.
