摘要： A method of producing novel polyester yarns, threads or fabrics in which a previously unstretched melt-spun yarn such as polyethylene terephthalate is stretched upon a stationary heated stretching pin of a diameter of 15-60mm. and a pin temperature of 60.degree.-105.degree.C., the yarn being drawn at a stretching ratio of 60-80 percent of the normal ratio while placing the yarn under a thread tension after the pin of 0.2 to 1.1 grams/denier with a ratio of thread tension after the pin to that before the pin of 1:1.5 to 1.4. The resulting novel yarn is characterized by an elongation at breaking point of 30-80 percent, a boiling shrinkage capacity (at 100.degree.C. in water) of 20-50 percent and a large number of random denier fluctuations or variations per unit length of about 15-35 nodules per meter spaced at random intervals of about 0.5 to 8 centimeters. These yarns are particularly useful when fabricated into a textile structure and dyed, e.g. with basic dyes or dispersion dyes, so as to provide a different strength of dyeing as between the thicker and thinner portions of the yarn.
摘要翻译：一种生产新型聚酯纱线，纱线或织物的方法，其中先前未拉伸的熔纺纱如聚对苯二甲酸乙二醇酯在直径15-60mm的固定加热拉伸销上拉伸。针脚温度为60°-105℃，纱线以正常比例的60-80％的拉伸比拉伸，同时将纱线放置在丝线张力之后，针脚为0.2至1.1克/旦尼尔针脚之后的线张力与针脚之间的比例为1：1.5至1.4。所得到的新型纱线的特征在于断裂伸长率为30-80％，沸水收缩能力（在水中为100℃）为20-50％，并且大量的随机旦数波动或每单位长度的变化约15-35个结核每米间隔约0.5至8厘米的随机间隔。当制造成纺织品结构并染色时，这些纱线尤其有用。使用碱性染料或分散染料，以便在纱线的较厚部分和较薄部分之间提供不同的染色强度。

摘要： An apparatus and process for smoothing and densifying both the upper and lower surfaces of a filamentary mat or sheet as rows of freshly melt spun filaments are permitted to fall freely onto the surface of a liquid cooling bath whereby the individual filaments spread laterally at the bath surface to form helical to sinuous loops which then become self-bonded at overlapping points of intersection within a short distance below the bath surface. A flattening or densifying of upper and lower surfaces of the mat into a more rigid structural member is accomplished by inserting at least one pair of downwardly diverging plates within the bath such that the upper apex thereof extends parallel to the rows of filaments and falls within at least one outermost row of filaments, thereby deflecting such a row inwardly and upwardly over the apex as it is incorporated into an outer bonded surface of the mat.

摘要： A reinforced matting of melt-spun, interlooped, substantially amorphous and continuous synthetic thermoplastic filaments of which one set of filaments is applied with random penetration to a flat, latticed structure such as a fabric mesh or wire screen while another set of filaments may be added to form at least one and preferably several additional rows of interlooped filaments adhered to the first set of filaments carried by the latticed structure as a reinforcing member. This matting is made in a specific process requiring the first set of filaments to be melt spun at an angle inclined from the vertical onto the reinforcing member as a vertically conducted continuous band while the second set of filaments may be waterlaid on the surface of a liquid cooling medium, and the resulting filaments are then collected at or just below the liquid surface for adherent interlooping contact with each other and are carried on the reinforcing member through the bath as the filaments are completely solidified into a coherent self-bonded matting of high longitudinal and transverse strength.
