    • A process of making a low-shrinkage, air-textured yarn, in particular sewing yarn, of synthetic, pre-oriented polymer multifilaments, includes the steps of drawing multifilaments in the form of a single strand at a temperature of about 180.degree. to 230.degree. C. by a factor of 1.6 to 2.5, air-texturing the drawn strand at a rate of overfeed of 1.03 to 1.20 to form a single-strand raw yarn, feeding the raw yarn to a fluffing zone of predetermined length at a rate of overfeed of 1.003 to 1.025, winding the fluffy raw yarn at slightest possible tension, reeling off and twisting the wound raw yarn, and treating the twisted raw yarn at a temperature of 125.degree. to 135.degree. C. over 1 to 3 hours in a dyeing unit, and, optionally, dyeing the raw yarn. The process is equally applicable for making plied yarns.

    • In accordance with the invention there is provided a synthetic sewing thread of multifilament construction characterized by its ability to lessen the buildup of heat at the needle of a high speed sewing machine during the operation thereof, even during the sewing of relatively heavy weight fabrics, so as to allow the thread to be utilized as a substitute for the sewing threads conventionally required in high temperature sewing applications, such as cotton spun yarns or cotton sheathed core yarns. The thread is of substantially uniform cross section throughout, devoid of alternating thick and thin areas to provide a smooth more uniform sewing thread. The thread comprises a plurality of texturized continuous synthetic filaments, the filaments having a nonlinear crimped configuration providing bulk to the thread and being entangled with one another along the length of the thread by being directed through a fluid jet under a relatively high pressure of at least 80 p.s.i. and being further bound together by twist. The thread has a heat protective lubricant coating applied thereto and penetrating the filament bundle.
    • 根据本发明,提供了一种复丝结构的合成缝纫线,其特征在于,即使在相对较重的织物缝制期间,其能够减轻高速缝纫机在其操作过程中的针的积聚,因此 以使线可以用作高温缝纫应用中通常所需的缝合线,例如棉纱或棉铠装芯纱。 螺纹的横截面基本均匀,没有交替的厚薄区域,以提供光滑的更均匀的缝纫线。 所述线包括多个纹理化的连续合成长丝,所述长丝具有非线性卷曲构造,其向所述螺纹提供松散并且沿着所述螺纹的长度彼此缠结,通过在至少相对高的压力下被引导通过流体射流 80 psi 并通过扭曲进一步绑定在一起。 螺纹具有施加到其上并穿透细丝束的耐热润滑剂涂层。

    • A method and apparatus are disclosed for the production of a novel industrial polyester filament yarn of improved uniformity wherein a plurality of filaments are melt-spun into a heated zone coupled with controlled cooling. The yarn produced has improved long and short term Uster uniformity and improved uniformity of physical properties, particularly breaking strength, as shown by a reduced standard deviation of breaking strength. The yarn is produced by melt spinning into a heated zone which maintains the filaments molten for intervals below the spinneret face and subsequently quenching the filaments with a radial outflow of cooling gases, thereby producing a low birefringence yarn which is capable of being drawn at high draw ratios to high tenacities.
