  • the manufacturing method of the anti-pilling fabric of this embodiment is applicable also to the woven and knitted fabric etc. which have the surface in which the raising process was given.
  • processing methods such as needle cloth raising treatment and emery raising treatment, pile fabric And woven fabrics such as center cut of double russell knitted fabrics.
  • At least one surface of a woven or knitted fabric having a brushed surface is hair-baked to form a molten ball at the end of the short fiber, and the fluff of the short fiber formed on one surface of the obtained woven or knitted fabric
  • the molten ball at the tip portion may be abraded by rubbing to form a polishing mark.
  • the long fibers are cut by weaving, knitting, raising treatment, etc. on the surface of a green machine which is woven and knitted using long fibers of thermoplastic synthetic fibers as raw yarns.
  • the present invention is also applicable to woven fabrics and the like in which short fibers are present.
  • Heat treatment is performed to eliminate the influence of the non-uniform heat history of the synthetic fiber. Performing heat setting is preferred to achieve the dimensional stability and uniform dyeing of the fabric. In the case of polyester fiber or nylon fiber, heat treatment is performed at 180 ° C. for about 30 seconds to 1 minute.
  • staining There is no particular limitation on the staining. Dyeing may be performed by dyeing (fir dyeing) or continuous dyeing, and dyeing is common. Although polyester is partially dyed continuously, the texture is cured and the flexibility is lost. In dyeing, when the hair is baked before dyeing, the dyeability of the molten ball and the ground is different to cause dyeing, but in the present embodiment, the molten ball on the surface of the fabric is removed by polishing, so dyeing is generated. There is no problem of Inhomogeneous hair burning produces stained streaks.
  • the fabric may be subjected to hair burning and polishing, that is, any of pre-hair-staining and post-hair-staining may be employed. (Finish drying) It is then dried and finished.
  • a woven or knitted fabric with an anti-pilling grade 1 to 2 including short fibers of thermoplastic synthetic fibers can be treated as an anti-pilling grade It can be made a third or higher grade, preferably a fourth or higher grade, more preferably a fifth grade, and can be made into a woven or knitted fabric in which a reduction in strength and deterioration in texture are also suppressed.
  • the woven or knitted fabric which has been subjected to the anti-pilling measures of the present embodiment is also excellent in durability because the anti-pilling performance is maintained even after repeated washing, as shown in the following examples.
  • Example 1 Production of spun polyester product (grilled + polished product) A spun polyester fiber (short fiber of polyester fiber, 1.6 denier, 38 mm cut) is spun according to a conventional method, and polyester spun yarn (30 count) I got The obtained polyester spun yarn is warped as a warp, and the warped warp is pasted with a paste made mainly of poval, and the polyester spun yarn obtained similarly is used as weft, and the warp density is 90 / A plain weave greige was woven with an inch (2.54 cm) and a weft density of 70 / inch. After desizing and refining the obtained green machine, both sides of the fabric were baked with a gas burner (80 m / min) to form molten balls in the fabric.
  • a gas burner 80 m / min
  • both sides of the fabric were polished with a belt sander (mesh # 1000) to remove molten balls generated on the surface of the fabric. Thereafter, through a heat setting process at 180 ° C. for 1 minute, a dye dyeing process by dyeing, and a drying process, a plain weave test fabric composed of spun polyester fibers was obtained.
  • Example 2 Production of spun nylon product (grilled + polished product) A spun nylon fiber (short fiber of nylon 66 fiber, 1.7 denier, 38 mm cut) is spun according to a conventional method, and a nylon spun yarn (30 Got the count). The obtained nylon spun yarn is warped as warp, and the warped warp is glued with a paste made mainly of poval, and the nylon spun yarn obtained similarly is used for weft, and the warp density is 90 // Weaved a plain weave green machine with an inch, weft density 70 yarns / inch. After desizing and refining the obtained green machine, both sides of the fabric were baked with a gas burner (80 m / min) to form molten balls in the fabric.
  • a gas burner 80 m / min
  • both sides of the fabric were polished with a belt sander (mesh # 1000) to remove molten balls generated on the surface of the fabric. Thereafter, through a heat setting process at 180 ° C. for 1 minute, a dye dyeing process by dyeing, and a drying process, a test fabric composed of spun nylon fibers was obtained.
  • Blended spinning (40th speed) 2 in which polyester fiber (38 mm cut, top dyed) and rayon fiber (38 mm cut) were spun at a mixing ratio of 65: 35 Prepare a pre-dyed cloth (90 yarns x 90 yarns) woven using a twisted yarn (final mixing ratio 61: 33: 6) consisting of a book and one polyurethane filament yarn (40 denier) as warp yarns and weft yarns, Furthermore, the coat was brushed. The fabric was gas fired (80 m / min) to form a melt ball, and then both sides of the fabric were polished with a belt sander (mesh # 1000) to remove the melt ball generated on the fabric surface. Thereafter, through a heat setting process at 180 ° C. for 1 minute, a plain weave test fabric composed of a blended material was obtained.
  • the anti-pilling test and the tear strength test were carried out on samples without washing, after washing 10 times and after washing 30 times.
  • the tear strength test was omitted for the test samples obtained in Example 2 and Comparative Example 5 and Example 3, and the test samples obtained in Comparative Examples 6 and 7 were washed 30 times after washing.
  • the post anti-pilling test was also omitted.
  • the results are shown in Table 1 below.
  • the anti-pilling test was performed for 10 hours according to JIS L 1076 A method (method using an ICI type tester).
  • the test result was an average value of the determination results of four test pieces.
  • the tear strength test conformed to JIS L 1096 D (Pendulum method). Washing was carried out 30 times 10 times according to the JIS L 1930 C4M method (using tumble).
  • the anti-pilling grade is the highest grade even after 30 times of washing, and the anti-pilling property is extremely excellent. The texture was good and there was no decrease in strength.
  • the anti-pilling grade of Comparative Example 1 produced without hair burning and polishing is grade 1

  • that of Comparative example 7 The anti-pilling grade was grade 1 and numerous pillings occurred at the manufacturing stage.
  • the anti-pilling grade is a preferable result of the fifth grade similarly to Examples 1 and 2.
  • Example 6 the anti-pilling grade is 3.5, and the anti-pilling property is improved as compared with Comparative Example 7, but the presence of a large number of molten balls produced by hair-burning causes the fabric to have a touch feeling. It was bad and damaged the commercial value.
  • the anti-pilling fabric of the present invention has excellent anti-pilling properties, good texture, and no significant decrease in strength, so it is a variety of clothing and other textile products having the desired texture and appearance, and has been put to practical use It can be suitably used as a woven or knitted fabric using spun yarn of synthetic fibers, which has been difficult.
