Zusammenfassung: | The invention relates to a process for creping woven fabrics made of cellulosic fibres meant for making clothing articles, consisting in coating the prepared, dyed and/or printed woven fabrics with a paste containing a synthetic or natural thickener, a reserving agent in a ratio of 1/2...1/10, a fixing agent, possibly a softener and 25% ammonia for a pH=8...9, after the drying and fixing operations, the woven fabrics being nip-padded with a solution containing 26...30°Be NaOH, then washed and neutralized in a manner known per se. The process ensures the manufacturing of crepe fabrics with uniform appearence, resistant to repeated washing and with a pleasant feel by wearing.
Invenţia se referă la un procedeu de creponare a ţesăturilor din fibre celulozice destinate confecţionării articolelor de îmbrăcăminte exterioară, constând în aceea că, pe ţesăturile pregătite, vopsite şi/sau imprimate se depune o pastă care conţine îngroşător sintetic sau natural, produs de rezervare, în raportul 1/2...1/10, fixator, eventual emolient şi amoniac 25% pentru pH=8...9, după uscare şi fixare ţesăturile fiind fulardate cu o soluţie ce conţine 26...30°Be NaOH şi apoi spălate, neutralizate în condiţii în sine cunoscute. Procedeul asigură realizarea unor ţesături creponate cu aspectuniform, rezistente la spălări repetate şi cu tuşeu plăcut la purtare. |
