    Abstract: A method for manufacturing improved synthetic bonded filament yarn by forming a unit composite from matrix and island components, assembling a plurality of the unit composites into a randomly bundled multifilament yarn and heating the multifilament yarn at a temperature between the melting points of both components. The cross section of the unit composite can be obtained in any of so-called sheath-core configuration, randomly distributed configuration and bimetallike configuration of the components. The bonded filament yarn has excellent flexibility and a unique surface condition having many wrinkles thereon and the bonded filament yarn of the present invention can be advantageously used for numerous industrial uses such as chafer fabrics of tires, bowstrings, fishing nets, guts of rackets, etc.

    Abstract translation: 通过从基体和岛部件形成单元复合材料制造改进的合成接合长丝纱线的方法，将多个单元复合材料组装成随机卷绕的复丝纱线，并在两个部件的熔点之间的温度下加热复丝纱线。 所述单元复合材料的横截面可以以任何所谓的皮芯构型，组件的随机分布构型和双金属配置来获得。 粘合长丝纱线具有优异的柔软性和独特的表面状况，其上具有许多皱纹，本发明的粘合长丝纱线可有利地用于许多工业用途，例如轮胎胎圈包布织物，弓弦织物，渔网，球拍外套等 。

    Abstract: 1300467 Cellular Polyamide fibres TORAY INDUSTRIES Inc 1 Aug 1970 37266/70 Heading B5B [Also in Division C3] Cellular polyamide fibres are produced from a dispersion of a thermally stable polyalkylene ether modifier having a molecular weight of 600 to 60,000 in a polyamide, the dispersion containing between 0À2 and 3À5 millimole alkylene oxide units per gram of polyamide, by converting the dispersion into pellets, melt spinning the pellets into filaments, drawing the filaments until they have a predetermined orientation and extracting the modifier to produce filaments having 0À5 to 13% by volume of voids. The modifier is present in the pellets as particles, the average axial diameter of at least 50% of them being below 20Á. The birefringence of the filaments should be not less than (49 log 10 (8a+8)-32) Î 10 -3 where a is the millimoles of alkylene oxide units per gram of polyamide. The modifier may be a reaction product of a polyalkylene oxide such as polyethylene oxide or polypropylene oxide, with a polyamide monomer, such as a lactam, or oligomer. The modifier may also be a phosphoric acid ester, or a metal salt thereof, of a polyalkylene ether having at least one hydroxy radical. The modifier may be introduced into the polyamide by dissolving it in the polyamide monomer solution or mixing it with the monomer, and then polymerizing the monomer. The modifier may be removed from the filaments after spinning by dissolving it out with water or an organic solvent, such as a mixture of methanol and benzene, which does not dissolve the polyamide. The lustre of the fibre may be improved by addition of fine white particles whose maximum diameter is less than 10Á, the quantity of which is given by the formula where C is the quantity in per cent by weight and d is the difference between the refractive indeces of the polyamide and the particles. Suitable particulate materials are talc, CaCO 3 , titanium oxide and kaolinite. The fibres produced should have a ratio of strength of scattered light (I/I 0 ) as herein defined of from 1À5 to 15 and a lustre factor, also as herein defined, of from 20 to 90.
