Abstract: Synthetic fibers having natural fiber-like touch, gloss, texture and appearance are produced by spinning a polyester and a polyamide through a common spinneret simultaneously to form mixed filaments consisting of multisegment filaments, in each of which the polyester is divided by the polyamide into at least three segments, and polyester single component filaments, drawing the mixed filaments and then subjecting the drawn mixed filaments to a false twisting to fibrillate the multisegment filaments.

Abstract translation: 具有天然纤维状触感，光泽，质地和外观的合成纤维通过共同的喷丝头同时纺丝聚酯和聚酰胺而形成由多段长丝组成的混纺丝，其中聚酯被聚酰胺分成 最少三个片段和聚酯单组分长丝，拉伸混合的长丝，然后对拉伸的混合长丝进行假捻以使多段细丝原纤化。

Abstract: A spontaneously degradable fiber excellent in bulkiness, softness, stretchability and feeling, which comprises a lowly heat-shrinkable fiber component (A) made of a highly crystalline aliphatic polyester and a highly heat-shrinkable fiber component (B) made of an aliphatic polyester (such as lowly crystalline or non-crystalline aliphatic polyester, a block copolymer or mixture comprising aliphatic polyester as the main component and being composed of a high-melting component and a low-melting component, or the like). Further, fibers excellent in self-crimpability or self-bondability or separable fibers can be obtained by combining the fiber components (A) and (B) suitably to form a composite fiber or yarn.

Abstract: A biodegradable copolyester produced by copolymerizing a lactic acid compound as the main ingredient with PEG, an aliphatic polyester or an ester-forming sulfonic acid derivative and having an average molecular weight of 50,000 or above, a molding produced therefrom, such as composite fibers, and a process for producing the molding.
