    Abstract: A method, apparatus and product comprising producing a semicontinuous filament yarn having staple yarn characteristics from crimped tow comprising longitudinally slitting a deregistered tow comprising different fibers into strips of filaments either with or without a tow spreading stage and subsequently twisting the strips into yarn. The tows differ from each other in the fibers they contain, but each individual tow may contain a relatively uniform blend of different fibers.

    Abstract translation: 一种方法,装置和产品,包括从卷曲的丝束生产具有短纤维特征的半连续长丝纱线,其包括将包含不同纤维的脱排丝束纵向切割成具有或不具有丝束铺展阶段的丝条,然后将条带扭曲成纱线。 丝束在它们包含的纤维中彼此不同,但是每个单个的丝束可以包含不同纤维的相对均匀的混合物。
