  • the cotton fabric can be dyed by a dyeing process suitable for cotton fibers (e.g., reactive dyeing). During the dyeing process, only the normal cotton yarns are dyed, and the water-repellent yarns are not dyed, resulting in, e.g., a piece dyed denim-like fabric. This fabric has excellent fastness and does not cause problems such as color transfer.
  • FIG. 1 is a process chart showing a method for producing water-repellent fibers of an embodiment of the present invention.
  • the water-repellent treatment of a fiber assembly such as cotton, a fiber bundle, a yarn, or a gray fabric had not usually been performed because it was considered that the water-repellent cotton or fiber bundle would change the fiber lubricity and make spinning difficult. Moreover, it was considered that a good quality product was not able to be obtained, since the water-repellent yarn or gray fabric could not be dyed or could not be easily dyed.
  • the present inventors found that when the fiber assembly such as cotton, a fiber bundle, a yarn, or a gray fabric was subjected to a water-repellent treatment, although it had been recognized as a problem, a surprisingly wide range of product development could be achieved. Based on these findings, the present inventors have reached the present invention.

  • the cross-linked state of the water repellent agent means that an aqueous solution or dispersion containing a mixture of the water-repellent agent and a cross-linking agent is applied to the surface of the cellulose fibers, and then subjected to, e.g., heat curing so that the water-repellent agent is firmly integrated with the surface of the cellulose fibers.
  • the water repellency can be maintained in the subsequent dyeing or washing. Therefore, a portion of the cellulose fibers to which the water-repellent agent has been cross-linked will not be dyed and functions as a resist for piece dyeing.
  • the cellulose fibers are preferably at least one selected from natural cellulose fibers and regenerated cellulose fibers, and more preferably natural cellulose fibers.
  • natural cellulose fibers include cotton and hemp.
  • regenerated cellulose fibers include normal rayon, Bemberg rayon, solvent type rayon, and lyocell.

  • a heat curing type water-repellent agent is preferred in terms of durability.
  • the fluorine based water-repellent agent is used in combination with a cross-linking agent, and that the fluorine-based water-repellent agent is cross-linked and fixed to the surface of the cellulose fibers.
  • the cross-linking agent include a urethane cross-linking agent and an acrylic cross-linking agent. In this case, the urethane cross-linking agent is particularly preferred.

  • the fluorine content is measured as the ratio of the fluorine element to the total number of elements in, e.g., the water-repellent cotton, where the total number of elements is detected by a fluorescent X-ray analyzer and set to 100.
  • the fiber product of the present invention includes the cellulose water-repellent fibers.
  • the fiber product may be a piece dyed denim-like fabric.

  • the fabric including the water-repellent cotton spun yarns of the present invention can have a white pattern on a colored background.
  • a woven or knitted fabric using the spun yarns of the present invention can be piece dyed and have water repellency as a whole.
  • the water-repellent treatment may be performed after cotton dyeing or yarn dyeing.
  • the method for producing a fiber assembly including cellulose water-repellent fibers of the present invention includes the following steps of:
  • the water-repellent agent is applied to the fiber assembly by, e.g., impregnation, spraying, or padding. It is preferable that the water-repellent agent is dispersed in water before being applied to the fiber assembly. Thus, uniform application can be achieved.
  • the drying process and the heat curing process may be continuously performed with a heated air dryer.
  • the heat curing conditions are preferably such that the temperature is 150 to 190° C. and the time is 2 to 20 minutes. In this case, the cellulose fibers should not be damaged by heat.
  • the cotton or the fiber bundle is preferably opened. This is because the fibers may converge due to the water-repellent treatment.
  • FIG. 1 is a process chart showing a method for producing water-repellent fibers of an embodiment of the present invention.
  • raw cotton of cellulose fibers is blended and opened by a carding machine to form a web.
  • the web is drawn out to produce a sliver (fiber bundle).
  • the sliver is impregnated with an aqueous dispersion containing a water-repellent agent and a cross-linking agent, squeezed, dried, and heat cured so that the water-repellent agent is cross-linked and fixed to the surface of the cellulose fibers.
  • the fibers are blended again and go through a carding machine to form an opened web.
  • the opened web is drawn out to produce a sliver.
  • the sliver is spun into yarn by roving and fine spinning.
  • the spun yarn is used to make a woven fabric or a knitted fabric.
  • the woven fabric or the knitted fabric may be made by combining different types of yarns, e.g., the water-repellent spun yarns thus obtained and normal spun yarns that have not been subjected to a water-repellent treatment.
  • the normal spun yarns that have not been subjected to a water-repellent treatment are dyed, but the water-repellent spun yarns are not dyed, so that a non-uniformly dyed fabric is obtained.
  • the non-uniformly dyed fabric is useful as a denim-like fabric.
  • the water-repellent agent is applied to the fiber bundle because this allows the fibers to be treated continuously and also facilitates material handling.
  • Water-repellent cotton was produced by the method shown in FIG. 1 .
  • 200 L of a chemical solution was prepared, which contained 20 L of a fluorine-based water-repellent agent “NE GUARD S-09” (trade name) manufactured by NICCA CHEMICAL CO., LTD., 4 L of a urethane cross-linking agent “NK ASSIST V” (trade name) manufactured by NICCA CHEMICAL CO., LTD., 1 L of a penetrating agent “INVADINE 650” (trade name) manufactured by Huntsman Corporation, and water.
  • a sliver was impregnated with the chemical solution, squeezed by a mangle, dried, and heat cured at 170° C.
  • the fluorine content of the resulting water-repellent cotton was measured by a fluorescent X-ray analyzer (ZSX100e: EZ scanning method) manufactured by Rigaku Corporation and was 0.4% by mass.
  • the water-repellent cotton was returned to the blending process, thus forming an opened web.
  • the opened web was drawn out to produce a sliver.
  • the sliver was spun into yarn by roving and fine spinning (ring spinning).
  • the English count of the spun yarn was 7.

  • This fabric was singed, desized, scoured, bleached, and mercerized in the usual manner. Then, the fabric was impregnated with a reactive dye in the usual manner, and thus the reactive dye imparted color to the fabric and was fixed to the fabric.
  • the fabric was subjected to a finishing treatment with a softening agent, providing a denim-like fabric in which the warp was dyed.
  • the finished mass (weight per unit area) of the fabric was 380 g/m 2 .
  • the passage of the water-repellent cotton from the weaving process to the dyeing process was not different from that of normal cotton.
  • the water-repellent spun yarns serving as the weft appeared on the back side of the denim-like fabric.
  • the fluorine content of these water-repellent spun yarns was measured from the back side with the same apparatus and method as those used for the water-repellent cotton and was 0.3% by mass.
  • the fabric thus obtained was made of 100% cotton yarn and had good texture.
  • a washing test was performed by washing this fabric 20 times with water in accordance with the method defined in JIS L 0001: 2014 (code number 141). Consequently, the fabric caused neither color fading nor color transfer.
  • the results of a wash fastness test showed that the fabric was grade 4 to 5 for color change and grade 4 to 5 for staining, which were about the same as the typical piece dyeing (e.g., alkali-steaming method) of cotton fabrics. Further, the fabric had better fastness than the denim in which the warp had been indigo-dyed before the yarns were woven into cloth.
  • the typical indigo-dyed denim was grade 2 for dry (warp direction) and grade 1 for wet (warp direction), while the fabric of this example was grade 4 to 5 for dry (warp direction) and grade 2 for wet (warp direction). Accordingly, the fabric of this example achieved good results.
