  • the total fineness of the core and/or sheath of the mixed yarn is preferably 10 to 60 dtex (more preferably 15 to 40 dtex).
  • the function of the sheath in the blended yarn is that when the core yarn shrinks significantly due to heat treatment, the sheath yarn swells into a mini pile shape, forming a fine uneven structure on the surface of the fabric, thereby enhancing the water repellency on the outside and at the same time imparting a cotton-like spun-like texture and appearance to the surface of the fabric.

After ten washings as specified in JIS L0217-1995 (using JAFET standard detergent blend), the water-repellency was grade 4. In addition, a fine uneven structure was formed on the surface of the fabric, and the water-repellent rolling angle was 9 degrees, the feel (good), and the appearance (good), making it a water-repellent fabric that not only had water repellency but also had a spun-like appearance and feel. The evaluation results are shown in Table 1.

Abstract

La présente invention concerne un tissu tissé hydrofuge et un produit fibreux qui sont excellents non seulement sur le plan de l'hydrophobicité, mais également des propriétés d'aspect et de texture de type filé. Le tissu selon l'invention est formé par finition hydrofuge et comprend des fils de filaments combinés de type âme-gaine dans lesquels une partie âme est un fil non frisé et la différence de longueur de fil entre la partie âme et une partie gaine est de 25 % ou supérieure.
