    • An elastic fiber having good stable viscosity and dye fastness and a manufacturing method thereof are provided to melt and mix the hyper-branched polymer with the conventional polyurethane polymer with a proper rate. A hyper-branched polymer is mixed with polyurethane by the ratio of 1:99 to 15:85 and then the spin process is performed so that the polyurethane elastic fiber is manufactured. The polyurethane precursor is manufactured by the reaction of the organic diisocyanate and the high polymer diol. The polyurethane precursor is dissolved in the organic solvent and reacted with diamine and mono amine so that the segment polyurethane used to manufacture polyurethane is manufactured. The examples of the organic di-isocyanate is 4,4'-diphenylmethane diisocyanate, 1,5'-naphthalene diisocyanate, 1,4'-phenylene diisocyanate, hexamethylene diisocyanate, 1,4'-cyclohexane diisocyanate, 4,4'-dicyclohexyl methane diisocyanate and isophoron diisocyanate and the like.

    • PURPOSE: A method for preparing yarn for weaving a cover fabric by twisting rayon yarn and acrylic yarn half-and-half is provided. Whereby, the obtained yarn has high surface strength and excellent durability and gives soft feeling without irritating the skin. CONSTITUTION: The titled yarn is prepared by the process consisting of: twisting rayon yarn and acrylic yarn to produce a filament by hanging the same number of a rayon yarn bobbin and acrylic yarn bobbin on a twisting machine; twisting to produce a blended yarn in a weight ratio of 50% respectively by hanging four rayon yarn bobbins and four acrylic yarn bobbins on the twisting machine; retwisting rayon yarn and acrylic yarn half-and-half by hanging the blended yarn bobbin on the twisting machine to produce 32 blended yarn; and TM treating.
    • 目的:提供一种用于通过扭转人造丝和丙烯酸纱线半捻编织覆盖织物的纱线的方法。 由此得到的纱线具有高的表面强度和优异的耐久性,并且具有柔软的感觉而不刺激皮肤。 构成:通过以下工序制造标题纱线:将捻丝纱和丙烯酸纱线捻合,通过将相同数量的人造丝纱线架和丙烯酸纱线筒管悬挂在捻线机上来制造长丝; 通过在加捻机上悬挂四根人造丝纱线架和四根丙烯酸纱线筒,分别捻合重量比为50%的混纺纱线; 将混纺纱线架挂在捻线机上,制成32根混纺纱线,将人造丝和丙烯酸纱线重新加捻一半; 和TM治疗。
