Abstract
A starch fiber produced by a spinning process and comprising: PA1 A A first amount of 1 to 100 parts of a starch melt-spinnable composition comprising PA2 1. a second amount of 56 to 96 parts of at least one modified and/or unmodified starch, PA2 2. a third amount of 4 to 40 parts of at least one destructuring agent, PA1 3. a fourth amount of 0 to 4 parts of at least one additive, selected from urea, urea derivatives, emulsifiers, lubricants, and proteins and their alkali salts, components 1, 2 and 3 totaling 100 parts; and PA1 B a fifth amount of 99 to 0 parts of at least one melt-spinnable polymer, ingredients A and B totaling 100 parts. In addition, there may also be included 0 to 20 parts of conventional additives for melt spinning compositions. The invention further relates to a process for the production of these starch fibers from this melt spinning composition, and to uses for fibers which, by modification with the starch melt-spinnable composition, have special properties.
