Abstract

Kaliptan çekilmis liyosel esyalarin imalati için bir yöntem anlatilmistir; burada üçüncül amin N-oksitte bir selüloz çözeltisi, bir kalip yoluyla bir hava araligi boyunca pihtilastirma banyosuna çekilir; hava araligina hava saglanir ve buradan bosaltilir; yöntemin özelligi, hava araliginin, kalip yüzeyine bitisik bir birinci bölge ve kalip yüzeyinden daha uzakta ikinci bir bölge içermesidir; birinci bölgeye saglanan havanin nem mühtevasi, ikinci bölgeye saglanan havanin nem muhtevasindan daha düsük bir degerde muhafaza edilir. Yöntem, gelistirilmis bükülebilirlik saglar ve azaltilmis fibrillesme egilimi sergileyen liyosel filamanlari saglayabilir.A method is described for the manufacture of lyocell articles drawn from the die; wherein the tertiary amine N-oxide cellulose solution is drawn through a die into the coagulation bath through an air gap; air is supplied to the air gap and emptied therefrom; the feature of the method is that the air gap includes a first zone adjacent to the mold surface and a second zone further away from the mold surface; The moisture content of the air supplied to the first zone is maintained at a lower value than the moisture content of the air supplied to the second zone. The method provides improved bendability and can provide lyocell filaments that exhibit a reduced tendency to fibrillation.
