    Abstract: A yarn structure is provided that imparts improved wrinkle resistance in fabrics produced therefrom. The yarn is composed of plurality of filaments or strands that are intermittently connected or fused by an essentially permanent bond, i.e., analogous to spot welding, along their lengths. The appropriate distribution of these points of bonding, preferably varying from a distance of about 20 filament diameters as an upper limit to a frequency of about one in 2,000 filament diameters measured along the length of the fiber as a lower density limit, is obtained by removing any size, lubricant or finish from the fiber, applying an electrical charge, and spraying or otherwise applying a thermoplastic polymer to the surface of the fiber. Droplets of the applied polymer adhere to the fiber and provide effective jointer points between adjacent fibers.

    Abstract translation: 提供了一种纱线结构，其在由其制备的织物中赋予改善的抗皱性。 纱线由多根长丝或股线构成，长丝或股线沿其长度通过基本上永久的接合，即类似于点焊而间断地连接或熔合。 这些粘合点的适当分布优选地从作为上限的大约20个长丝直径的距离变化到沿纤维的长度测量的2000个细丝直径的约1个的频率作为较低的密度极限，通过去除 来自纤维的任何尺寸，润滑剂或光洁度，施加电荷，以及喷射或以其它方式将热塑性聚合物施加到纤维的表面。 施加的聚合物的液滴粘附到纤维上并在相邻纤维之间提供有效的接合点。

    Abstract: THE INVENTION CONTEMPLATES THE PREPARATION OF FIBRILLATED YARNS OR STRANDS HAVING HIGH BULK AND GOOD TACTILE PROPERTIES FROM A UNITARY STRUCTURE, E.G. MONOFLAMENTS. THE MONOFILS, TAPES, FILMS AND THE LIKE HEREAFTER REFERRED TO AS A MONOFIL ARE EXTRUDED FROM POLYMER MIXTURES CONSISTING OF (A) A LOW MOLECULAR WEIGHT POLYESTER AND (B) ONE OR MORE OF THE FOLLOWING POLYMERS; (I) A FIBER FORMING POLYAMIDE, (II) A FIBER FORMING POLYESTER AND (III) A FIBER FORMING POLYOLEFIN IN BLENDS OR MIXTURES WHOSE COMPOSITION IS CAPABLE OF PRODUCING SUITABLE FIBERS. THE SPLITTING OF THE MONOFIL INTO A RELATIVELY HIHG BULK STRUCTURE CONTAINING MANY FIBRILS IS EFFECTED BY SUITABLE MECHANICAL WORKING WHICH BREAKS OR FISSURES THE MONOFIL INTO SEPARATE FIBRILS.

    Abstract: A COLD FORMABLE SANDWICH STRUCTURE WHICH HAS A THERMOSETTING RESINOUS CORE BETWEEN FACE SHEETS COMPRISING LAMINAE OF A THERMOPLASTIC SHEET WHICH INCORPORATES A METALLIC FOIL. THE METAL FOIL-THERMOPLASTIC RESIN FACING SHEETS ARE OF SUFFICIENT THICKNESS AND STRENGTH SO THAT THE SANDWICH CONTAINING THE THERMOSETTING CORE BETWEEN THE FACE SHEETS MAY BE COLD-FORMED INTO SHAPED ARTICLES AND SUCH SHAPES AS IS IMPARTED TO IT IS RETAINED BY THE THERMO-
