    Abstract: Composite yarns have a filamentary core provided with at least one elastic performance filament and at least one inelastic control filament. A fibrous sheath, preferably formed from spun staple fibers, surrounds the filamentary core, preferably substantially along the entire length thereof. The at least one elastic performance filament most preferably includes a spandex and/or a lastol filament. The at least one inelastic control filament is most preferably formed of a textured polymer or copolymer of a polyamide, a polyester, a polyolefin and mixtures thereof. Preferably, the fibrous sheath is formed of synthetic and/or natural staple fibers, most preferably staple cotton fibers. The elastic composite fibers find particular utility as a component part of a woven textile fabric, especially as a stretch denim fabric, which exhibits advantageous elastic recovery of at least about 95.0% (ASTM D3107).

    Abstract: A tubular casing for use with food products which includes knitted stockinette, longitudinal threads and circumferential spiral threads that are held to stockinette by stitches located along the length of the casing. Each thread comprises an elastic thread formed from an inextensible yarn spirally wrapped around the outside of a rubber thread. As thread is stretched, the rubber thread extends and the helix angle of the spirally wrapped yarn reduces to the point where the yarn approximates a straight line. The inextensible yarn resists further stretching beyond this point. This point is the elastic limit for thread and it can be adjusted by varying the helix angle during manufacture of the elastic thread. Threads therefore allow the casing to be filed to a predetermined maximum diameter and result in the filled casing having a constant diameter throughout its length.

    Abstract translation: 一种用于食品的管状壳体，其包括针织袜子，纵向丝线和圆周螺旋形螺纹，其通过沿着壳体的长度定位的针脚而被保持在料筒上。 每个螺纹包括由螺旋状缠绕在橡胶线外侧的不可伸长纱线形成的弹性线。 当螺纹被拉伸时，橡胶螺纹延伸并且螺旋缠绕纱线的螺旋角度减小到纱线接近直线的点。 不可延伸的纱线抵抗超出这一点的进一步拉伸。 这一点是螺纹的弹性极限，并且可以通过在弹性丝的制造期间改变螺旋角来调节。 因此，螺纹允许外壳被放置到预定的最大直径，并且导致填充的外壳在整个长度上具有恒定的直径。

    Abstract: A process is provided for making a yarn with improved properties, such as lowered susceptibility to picks and snags. The yarn consists of a spandex core that is tightly covered with a nylon fiber, which tight covering is achieved by heat treatment. A knitted fabric is further provided, that is made of yarn consisting of a spandex core and a nylon fiber, which has low susceptibility to picks, as well as to tears during its production and its use.

    Abstract: Cut resistant yarns suitable for knitting gloves and sleeves and methods of making the yarns are disclosed. The yarns are made up of a bundle of continuous filaments formed of a synthetic material, e.g., polyethylene, polypropylene, nylon or polyolefin, and a stretchable yarn, e.g., Spandex® or Lycra®. The yarns are made in such a manner that when completed the continuous filaments are substantially parallel to one another and to the longitudinal axis of the yarn so that items made from them will not twist or curl up, yet will provide good resistance to cutting.

    Abstract: A continuous method for producing composite elastic yarns at speeds up to 700 m/min by (a) stretching (drafting) an elastomeric yarn (e.g., spandex) by 2.0× (100%) to 10.5× (950%) while heating (max. heating temperature 220° C.) in a single or double stage draft, (b) air-jet entangling with a relatively inelastic yarn component to create a composite elastic yarn, and then (c) in-line heat-treating (max. heating temperature 240° C.) the composite elastic yarn. The initial draft stage(s) may also be carried out at ambient temperature. The resulting composite elastic yarn has improved stitch clarity, particularly suited for hosiery, and its properties can be tailored to provide fabric properties for knit and woven fabrics hitherto not possible with standard spandex yarns.

    Abstract translation: （a）在加热时（a）将弹性纱线（例如氨纶）拉伸（牵伸）2.0倍（100％）至10.5×（950％）），以加速速度（最大值），以700m / min的速度生产复合弹性纱线的连续方法 加热温度220℃），（b）用相对非弹性纱线组分的空气喷射缠结以产生复合弹性丝，然后（c）直列热处理（最大。 加热温度240℃）复合弹性纱线。 初始起始阶段也可以在环境温度下进行。 所得到的复合弹性纱线具有提高的针迹清晰度，特别适用于针织品，并且其性能可以被定制以提供迄今为止不能用标准氨纶纱线的针织和机织织物的织物性能。
