    摘要: This invention relates to an improved multifilament bundle which is made of thermoplastic polymer and usable without twisting and represents a linen-like touch. The multifilament bundle comprises a plurality of monofilaments of the same kind of thermoplastic polymer, said monofilaments being bonded thermally and partially together with neighboring at separated places thereof, each of said bonded places extending short distance along and in the longitudinal direction of monofilament, so as to make the constituent monofilaments coherent with each other into a non-torqued, non-bulky continuous yarn. This yarn can be fabricated, without sizing, into a textile fabric. This yarn can be used in various fields requiring untwisted yarns including sewing machine yarn. This yarn can be manufactured by passing a multifilament as spun at underfeed condition through a passage zone where heated fluid flows are brought into collision with each other. The fluid may preferably steam, while the material polymer may preferably 6- or 66 nylon.

    摘要: In manufacturing a fine-patterned thick film conductor structure, a thin film conductor layer having a film thickness of 0.1-10 .mu.m is formed on an insulating substrate and conductive material is then electroplated on the thin film conductor layer to the thickness of 34.9-190 .mu.m under the condition of a cathode current density of no less than 5 A/dm.sup.2. In patterning the conductors, a film thickness-to-conductor interspacing ratio is selected to be no less than 1.4 to prevent widthwise thickening of the conductors in the electroplating process. Resulting conductor structure has a circuit density of no less than 5 lines/mm and a film thickness of 35-200 .mu.m. It is useful for a high density printed circuit board and a miniature coil.

    摘要: The present invention is to provide a method of producing an adsorbent composed of micro-fibrils, comprising the steps of mixing two synthetic polymers in a mixing ratio of 20/80 - 80/20, both of said polymers being incompatible with each other when they are intimately mixed, subjecting the mixture in molten state to an extrusion molding to shape the article in the form of threads, ropes or films where at least one of the polymers assumes the forms of micro-fibrils, and thereafter treating the shaped article with a solvent which is incapable of dissolving or decomposing one polymer but capable of dissolving or decomposing the other constituent polymer.The polymer adsorbent obtained by the above method is characterized by superior adsorbing activity and high treating efficiency and can be used for a wide range of purpose of adsorption.
