摘要： Bulk yarns having improved elasticity and recovery and methods for their manufacture are described. A first embodiment of the invention involves providing a solution-dyed multifilament yarn of polybutylene terephthalate (PBT) and a multifilament yarn of a second thermoplastic polymer to an air jet texturizer such that the PBT component forms a core and the other yarn forms a plurality of loops and coils extending outwardly from the core. In addition to a high degree of elasticity and recovery, the composite yarn also has a low amount of shrinkage, which enables the yarns to be used in the production of woven fabrics without significant losses in fabric yield. Another embodiment of the invention involves false twisting a multifilament PBT yarn and a second multifilament yarn as individual threadlines to impart crimp thereto, then entangling the two components together using an air interlacing jet, to produce a bulk yarn having high elasticity and recovery. Because the two components have different optimal draw ratios, the process involves the simultaneous drawing of the components at different draw ratios such as by running different diameter first delivery rolls for the respective components on the first delivery shaft of the machine. Alternatively, a supplemental individually-controllable first delivery shaft can be provided on the machine for feeding one of the components at a different speed from the other, to thereby draw the components at different ratios relative to each other. The thus-crimped yarns are then entangled together using an air entanglement jet, to produce a bulk yarn having high elasticity and recovery.
摘要翻译：描述了具有改进的弹性和恢复的松散纱线及其制造方法。本发明的第一个实施方案涉及提供一种聚对苯二甲酸丁二醇酯（PBT）的溶液染色复丝纱线和第二热塑性聚合物复丝纱线到空气喷射结构织物上，使得PBT组分形成一个芯部，另一条纱线形成多个环和线圈从芯部向外延伸。除了高度的弹性和恢复之外，复合纱线还具有低的收缩量，这使得纱线可以用于机织织物的生产中，而织物产量没有显着的损失。本发明的另一实施例涉及将多丝PBT纱线和第二复丝纱线作为单独的丝线假捻以使其卷曲，然后使用空气交织射流将两个部件缠结在一起，以产生具有高弹性和恢复的松散纱线。由于两个部件具有不同的最佳拉伸比，所以该方法涉及以不同拉伸比同时拉伸部件，例如通过对机器的第一输送轴上的相应部件运行不同直径的第一输送辊。或者，可以在机器上提供补充的可单独控制的第一输送轴，用于以与另一个不同的速度供给部件中的一个，从而以相对于彼此的不同比例拉出部件。然后使用空气缠结射流将如此卷曲的纱线缠结在一起，以产生具有高弹性和恢复性的松散纱线。

摘要： A false-twisted polyester yarn of good dyeing and mechanical properties is produced by a process wherein a yarn consisting of an as-spun polyester fiber having a mean birefrigence index (.DELTA.n) of from 15.times.10.sup.-3 to 150.times.10.sup.-3 is heat-treated and continuously, subjected to a false twisting treatment or draw-false twisting treatment. A preferred apparatus used comprises a feed yarn creel, a false twisting heater and an optional stabilizing heater, a false twisting element and a winder, wherein a heat-treating heater of the non-contact type is arranged upstream of the false twisting heater and between the false twisting heater and the feed yarn creel, at a height substantially equal to the height of the feed yarn creel so that the heat-treating heater confronts the false twisting heater; and a yarn cooling zone is provided between the heat-treating heater and the false twisting heater.

摘要： Filament yarns composed of multicomponent fibers of the matrix/segment type are produced and processed into textile fabrics by false-twist texturing the multicomponent fibres made up of segments of varying deniers to cause softening the matrix to bond the filaments together over short, medium or longer sections of the yarn. After conversion of the yarns into fabrics, the fabrics are subjected to a shrinking treatment. The fabrics so treated have a reduced tendency to crease or wrinkle, better crease recovery and better dyeing properties. The denier of the lower denier segments should be finer than 0.6 dtex and the denier of the high denier segments should be at least 1 dtex; the weight ratio of low to high denier segments in the yarn ranges from about 25:75 to about 75:25. The matrix is preferably made of polyamide 6 while the segments are polyethylene terephthalate. The cross-sectional shapes of the fibers may e.g. resemble a toothwheel with fine peripheral segments and a coarser core, combinations of three-toothed wheels with 12 or 6 peripheral teeth or similar combinations of orange-shaped cross-sections such as 3 and 6 "slices".

摘要： Spun yarn-like high bulky textured polyester yarns comprised of two types of polyester multifilament component yarns A and B and having broken filaments, in which textured yarns there is a difference in length between the component yarns A and B, whereby very high bulkiness is imparted thereto. The individual filaments of the component yarn A have a fineness and an intrinsic viscosity less than those of the component yarns B. The spun yarn-like high bulky textured yarns have satisfactory pilling resistance and frosting resistance.The spun yarn-like high bulky textured yarns can be produced by a process comprising doubling two types of undrawn polyester multifilament yarns having different properties through an intertwisting regulative device and simultaneously draw-texturing the doubled undrawn yarns.
