Abstract: The present invention relates to a fiber obtainable or being obtained by a method comprising: spinning a melt comprising an aliphatic polyester, an aliphatic-aromatic polyester, and a polyhydroxyalkanoate through a hollow fiber spinning nozzle to obtain a precursor fiber; and cooling the precursor fiber under a temperature gradient, thereby obtaining the fiber. The invention also relates to yarns and clothings made from such fiber and to methods of preparing such fiber.
Abstract: This application relates to a biodegradable yarn which exhibits an increased flame resistance. The biodegradable yarn comprises from 25 to 55 weight-%, preferably from 35 to 45 weight-% of viscose fibers or of viscose filaments and from 45 to 65 weight-%, preferably from 50 to 60 weight-%, most preferably 55 weight-% of polybutylene succinate fibers. The viscose fibers or filaments are preferably free of chlorine. Further, the present application concerns a method for manufacturing a biodegradable yarn having an increased flame resistance.
