  • Patent number: 10597805
    Abstract: The present invention relates to a knitted fabric which can be produced at low cost and can exhibit a stable color effect, and a method of knitting such a fabric. A warp-knitted fabric (1) consists of a base (2) and ridge portions (6) formed along a knitting direction, each ridge portion (6) is composed of a top portion (3) and two side wall portions (4, 5) respectively formed at both sides of the top portion (3), and the top portion (3) and the side wall portions (4, 5) are respectively formed by chain-stitch rows formed by knitting yarns having different colors from one another. The warp-knitted fabric (1) exhibits a color effect such that the color thereof visually recognized by an observer who looks at the warp-knitted fabric (1) from a direction intersecting the knitting direction is changed in accordance with the position of the observer.

  • Publication number: 20190309449
    Abstract: A woven/knitted fabric (1) has a plurality of ridges (6) formed along one direction, and each ridge (6) is constituted by a top (3) and side walls (4), (5) under the top (3). At least one of the top (3) and side walls (4), (5) is different in color from other two of them. At least part of the plurality of ridges (6) is arranged such that a distance L4 between the ridges (6) adjacent to each other is 0.2 to 2.5 mm. The ridges (6) are set so as to satisfy the following relations: Ratio Ra=(L2+L3)/L4=0.8 to 7.9; Ratio Rb=L1/(L2+L3)=0.4 to 1.6; Ratio Rc=L2/L3=0.2 to 0.9; and Ratio Rd=L1/L5=0.4 to 1.2, where L1 is a width of the top (3), L2 is a thickness of the top (3), L3 is a height of the side walls (4), (5), and L5 is a distance between wall surfaces of the side walls (4), (5).

  • Patent number: 8900413
    Abstract: A nonwoven fabric suitable for electrical insulation or as a battery separator is provided. The nonwoven fabric includes a PPS fiber, the nonwoven fabric being obtainable by a process for papermaking and having a front surface with a water contact angle greater than that of a back surface of the nonwoven fabric by 5° or more. A suitable method for producing the nonwoven fabric includes dispersing an undrawn polyphenylene sulfide fiber in water, depositing the fiber to form paper, and performing heat and pressure treatment with a calender having two rolls with surface temperatures different by 10° C. or more.
