  • Patent number: 7767120
    Abstract: The present invention relates to multifilament crimped yarn comprising an aliphatic polyester and methods for producing thereof, and to carpets that are manufactured by using the crimped yarn. The present invention provides an aliphatic polyester multifilament crimped yarn for the carpets comprising an aliphatic polyester having a melting point of equal to or higher than 130° C., said multifilament crimped yarn having crimp elongation rate of the multifilament crimped yarn after being processed with boiling water of 3-35% and breaking strength of 1-5 cN/decitex.
    Type: Grant
    Filed: April 2, 2004
    Date of Patent: August 3, 2010
    Assignee: Toray Industries, Inc.

  • Patent number: 5637385
    Abstract: A high-strength ultra-fine fiber construction including a high-strength multi-filament yarn including ultra-fine filaments of a fineness of a single filament less than 0.8 denier, a tenacity of 6.5 g/d or more, and the elongation at break of the multi-filament yarn being 15% or more. In order to obtain such a fiber construction, islands-in-sea-type or divisional type conjugate spinning is initially carried out to obtain conjugate multi-filament yarns, which is subjected to weaving to produce a fabric, and a island component removing or dividing treatment is finally done in order to obtain the high-strength ultra-fine fiber in the fiber structure.Ultra-fine fibers of the desired strength together with a particular range of a cover factor provides all the advantages of the ultra-fine fibers. A reduced air permeability, when it is necessary, can be easily obtained. Namely, a desired mechanical property as well as a desired softness are both obtained, while the number of naps and filament breakages are reduced.
