  • Example 1 is the same as Example 1 except that a multifilament yarn made of ordinary polyethylene terephthalate is used as the weft yarn of the loop woven fabric, and 48 yarns having a total decitex of 200 dtex are used. A loop fabric was produced in the same manner.
  • the obtained loop fabric was in the same state as in Example 1 except that the ground warp and the loop were not fixed. Further, a test and a wearing test were conducted in the same manner as in Example 1.
  • the present invention has wide industrial applicability in technical fields such as loop fabrics, fasteners and clothing products.

Abstract

La présente invention concerne un textile en boucle et analogue, le textile en boucle étant un textile comprenant une chaîne et une trame. Pour une partie de la chaîne, un monofilament ayant une finesse de 180 à 1000 dtex est utilisé. La chaîne constituée par le monofilament se dresse à partir de la surface textile pour former des boucles. L'espace (DL) entre les pattes de la boucle est de 4 à 15 mm, la hauteur (HL) de la boucle est de 0,5 à 2,5 mm, HL/DL est de 0,1 à 0,4, et la densité des boucles est de 40 à 300 boucles/10 cm2. La surface de boucle est sensiblement parallèle à la chaîne. Les pattes des boucles sont agencées de façon uniforme dans la direction de trame, et les deux pattes de la boucle sont fixées au textile.
