摘要： The sticking between an array of melt spun eccentric bicomponent filaments converged together into yarn is avoided by selecting the filaments being converged so that the thin sheath regions of the filaments do not contact one another and conducting the convergence in two steps if the number of filaments required for the yarn is too great for convergence in one step while avoiding the aforesaid contact.

摘要： Novel self-crimping fibers and methods for their preparation. Embodiments are provided in which fibers are melt-spun from a non-elastomeric polyamide and a thermoplastic elastomer selected from the group consisting of a polyether block polyamide copolymer and a polycaprolactone polyester. The fibers may be knit or woven into textile articles including, inter alia, hosiery, pantyhose and stockings.

摘要： A composite yarn, which is bulky when relaxed and elongates to at least 100 percent greater length under tension, with quick recovery of the relaxed condition when tension is removed, is composed of uncrimped elastic yarn and at least five relatively inelastic continuous filaments entangled about the elastic yarn to provide protection and desirable textile properties. The composite yarn can be made at unusually high speeds by entangling the relatively inelastic filaments about stretched elastic yarn with jets of high velocity fluid impinged at an angle of 90.degree..+-.45.degree. to the yarn axis, using a filament feed rate which avoids formation of filament loops in the stretched yarn. Examples illustrate combining spandex elastic yarn at 4X stretch with nylon filaments at zero percent overfeed, when using feed rates of up to 789 yards per minute.
摘要翻译：一种复合纱线，其在松弛时体积大，并且在张力下伸长到至少100％的长度，当张力消除时快速恢复松弛状态，由未卷曲的弹性纱线组成，并且至少五个相对非弹性的连续长丝缠绕在弹性纱线提供保护和理想的纺织品性能。复合纱线可以以非常高的速度制造，通过使用长度为90°+/- 45°的角度的高速流体喷射与纱线轴线缠绕在拉伸的弹性纱线上缠绕相对非弹性的丝线，使用避免了丝线进给速率在拉伸纱线中形成丝线圈。示例说明当使用高达789码每分钟的进料速率时，以4％拉伸的氨纶弹性丝与尼龙长丝以零百分比的过量进行组合。
