摘要： The present invention discloses a moving multicavity texturing method for simultaneously texturing filaments which are commingled to form a yarn. The yarn readily knits producing a fabric which upon subsequent dyeing and shrinking produces a variable textured fabric similar in appearance to fabrics knit from natural fibers.

摘要： Multifilament thermoplastic synthetic yarn is textured by an improved process involving propelling the yarn through an energy tube by superheated steam to strike, at an oblique angle, an unyielding barrier within a chamber in which the yarn then forms a plug on a moving perforate surface. The improvement comprises heat-setting the yarn, before the texturing operation, at constant length to the point that its density increases to at least 50% of the difference between that of undrawn amorphous yarn and the maximum normally attainable in such yarn; and feeding the resulting yarn hot into the energy tube whereby tendency toward shrinkage of the yarn resulting from undergoing crimping is reduced, and/or a higher texture level is obtainable at given temperature of the crimping operation.
摘要翻译：多丝热塑性合成纱线通过改进的方法进行纹理化，其包括通过过热蒸汽将纱线推动通过能量管，以倾斜的角度撞击腔室内的不受阻碍的屏障，纱线然后在移动的穿孔表面上形成塞子。改进之处在于，在变形操作之前，将纱线定型为恒定长度，使其密度增加至未拉伸无定形纱线之间的差异的至少50％，并且在这种纱线中可获得的最大值。并将所得到的纱线进给到能量管中，由此在卷曲操作的给定温度下降低了由于卷曲而导致的纱线的收缩倾向和/或较高的织构水平。

摘要： Crimped foamed fibers are produced by a process which eliminates any mechanical deformation steps. The process comprises the step of forming foamed fibers having a plurality of randomly arranged cells distributed asymetrically over a given cross section and occupying at least about 10% of the cross sectional area of the fiber, and heating the foamed fibers while maintaining the fibers under no load condition to produce a crimped foamed fiber. The crimped foamed fibers are used in apparel, carpet fibers, thermal insulation, acoustic and filtration.

摘要： An improved moving cavity yarn texturing device is described. One improved feature is a two stage energy tube which provides for more effective filling of the moving cavity by the yarn. The first stage has a cross section with a major axis an a minor axis. The second stage has a cross section with a major axis and a minor axis whose ratio is less than that of the first stage. A second feature is an improved chamber design which employs a channel having a "V" shaped cross section which eliminates snagging of the yarn by the cavity.

摘要： A molten polymer containing a blowing agent and, usually, a nucleating agent, is spun into fibers with screen packs or equivalent structures upstream of the spinning apertures. The use of screen packs enables the production of fibers with finer bubbles, which are therefore susceptable to greater melt-drawdown and post-drawing and can have better tensile properties. Foamed polyamide fibers are produced with average bubble diameters one-twentieth or less, compared to the effective fiber diameter.

摘要： Continuous filaments are fed by aspiration into a stream of heated fluid. The filaments are then contacted with at least a second stream of heated fluid to increase the temperature of the filaments. The combined streams of fluid containing the filaments are directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass thereof producing crimps therein. One or more streams of heated fluid are then contacted with the mass of filaments to set the crimps. The crimped filaments emerge from the chamber through an outlet opening therein.

摘要： A tow of continuous filaments is fed by aspiration into a stream of compressible fluid. The stream containing the filaments is directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the compressible fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass of the tow and emerge from the chamber in crimped form.
