Definitions

  • the animal hair-like synthetic fiber is employed for producing a pile fabric which has the hand touchness and appearance closely similar to those of natural furs.
  • the present invention relates to an animal hair-like synthetic fiber, particularly to an animal hair-like synthetic fiber being capable of providing a pile fabric which has the hand touchness and appearance closely similar to those of natural furs.
  • the guard hairs or the middle hairs affect the hand touchness appearing on the surface thereof and these hairs are extremely thick and long.
  • the downy hairs which are thin and short affect the heat insulation and the elasticity of natural furs.
  • a fiber having a thickness of to I20 deniers is required as one corresponding to a guard hair or a middle hair of natural fur.
  • it had been found that such a fiber even if it was that having a sharpened end, endowed a pile fabric with only softness of the surface thereof and a hand touchness similar to that of a natural fur was not absolutely guaranteed.
  • An object of the present invention is to provide a novel animal hair-like synthetic fiber being capable of endowing a pile fabric for the imitation fur with the hand touchness, the appearance and the change of lie of hair closely similar to those of natural fur.
  • the other object of the invention is to provide a novel pile fabric having the hand touchness, the appearance and the change of lie of hair closely similar to those of natural fur.
  • FIG. 1 shows a survey sectional view of an animal hair-like synthetic fiber of the present invention.
  • FIG. 2 shows a device for measuring the hardness of DETAILED DESCRIPTION
  • the fibers planted on a knitting fabric are directed in nonparallel with each other in the direction perpendicular to the knitting fabric but at random in various directions to spoil the appearance of pile fabric and give a roughly hard and coarse hand touchness.
  • the fibers on a knitting fabric can be directed in parallel with each other but cannot give a good hand touchness due to their fine denier and in case the length of a pile is more than 10 to 15 mm., pilling is readily formed by rubbing to remarkably drop the quality of product.
  • a fiber having a coarse denier must be employed together with a fiber having a fine denier in a manner that the former comes out on the surface of a pile fabric compared with the latter.
  • the present invention it has become possible to obtain the hand touchness and appearance similar to those of natural furs as well as the effect to avoid the formation of pilling by making a fiber having a coarse denier narrow at the part thereof which will be caught by the knitting yarns of a knitting fabric as a base fabric of a pile fabric, that is to say, by providing the fiber with one or more narrow parts in any middle part thereof to diminish the rough hardness of a fiber having a coarse denier.
  • the number of the narrow part of the present animal hair-like fiber is not critical and varies in accordance with the length of the fiber or the method for planting the fiber in a base fabric.
  • pile fibers are woven into a knitting fabric by the knitting yarn but the position of the pile fiber which is caught by the knitting yarn is not always restricted to that near the middle point of the fiber from the viewpoint of the mechanism of sliver knitting machine. That is to say, a pile fiber having a length of less than 30mm. has many opportunities that the narrow part thereof is caught by a knitting yarn and therefore, in case of a pile fiber having such a length, only one narrow part is sufficient.
  • Examples of the synthetic fibers useful for an animal hair-like fiber include fibers made of at least one member selected from the group consisting of polyacrylonitriles, copolymers of acrylonitrile and vinyl chloride, polyamides, polyesters, polyolefins, polyvinyl chlorides and a blend polymer of polyvinyl chloride and polyvinyl alcohol. Above all, the fibers of polyacrylonitriles, copolymers of acrylonitrile and vinyl chloride, polyvinyl chlorides and a blend polymer of polyvinyl chloride and polyvinyl alcohol are more preferable. These fibers are employed in an undrawn fiber wherein drawing after spinning is not carried out or a low-drawn fiber which is drawn is less than three times.
  • An embodiment of process for producing the present animal hair-like fiber is as follows: A fiber as a starting material is heated in part and the heated point is drawn to a desired extent by pulling the both sides thereof to the opposite directions each other with a constant speed to give a fiber having a narrow part at the heated point of the center. The above operation is repeated to give a fiber having more than one narrow part. A sharpened end of the fiber is obtained by continuing the pulling in the above operation until the fiber is cut.
  • the above method is illustrated with reference to a manufacturing apparatus which is one embodiment.
  • As undrawn or low-drawn fiber bundle as a starting fiber bundle is fed into the apparatus through a feed roller to a desired length and the fiber bundle fed is grasped under loading a pressure through an air-cylinder by two pairs of graspers which are arranged with a separation in a vertical direction. Two pairs of graspers are moved to a desired distance upward and downward, respectively, with a constant speed by means of the revolution of a lead screw, with blowing a hot air from injection nozzles to the fiber bundle. On the way, the fiber bundle near the injection nozzles is heat-drawn to be thinner (Procedure 1).
  • the animal hair-like fiber of the present invention is applied to a pile fabric as an imitation fur.
  • the fiber of the present invention since it is one corresponding to the guard hair of a natural fur, is employed together with other fibers, such as acrylic fiber having a shorter length and smaller denier corresponding to the downy hair ofa natural fur.
  • the fiber of the present invention is planted into a suitable base fabric such as a knitting fabric.
  • the obtained fabric is backed by an appropriate means such as a resin in order to prevent the piles from falling out and the resultant is subjected to a polishing finish to give a product.
  • the other applications of the present fiber include a false eyelash, a writing brush, a paint-brush, and the like.
  • EXAMPLE 1 To 20 parts by weight of an acrylonitrile-vinyl chloride (40:60 by weight) copolymer was added 2 parts by weight of a stabilizer and 78 parts by weight of acetone and the mixture was dissolved to give a spinning solution. The spinning solution was subjected to spinning and drawn to an extent of 1.7 times original length after the spinning to give a starting fiber (the denier of a single fiber: 40; the amount of the fiber: 1,000 strands).
  • the fiber was treated under the following conditions to give the instant fibers having one narrow part in the intermediate thereof.
  • End of fiber Both ends are sharpened.
  • Heating method by dry hot air Heating temperature: 145C.
  • L and L respectively: 15 to 25 mm.
  • d and d respectively: less than 30 u.
  • the hardness of the fiber was compared with those of the hair of fox and a conventional acrylic fiber having a denier of 40.
  • the hardness mentioned here was measured by the method as shown in FIG. 2.
  • l is a sample to be tested
  • 2 is a table
  • 3 is a load.
  • a sample 1 to betested was placed on the table 2 so that the length of 50 mm. was pushed out of the edge of the table.
  • the hardness was estimated from the vertical distance, S, between the face of the table 2 and the top of the sample l'hanging down. The result thereof is shown in Table 2.
  • EXAMPLE 2 The animal hair-like fibers having two narrow parts in the intermediate thereof and both sharpened ends were produced by the procedure as explained in Example 1. Their particulars are as follows:
  • Mean fiber length 150 mm.'
  • L and L respectively: 15 to 25 mm.
  • the obtained fibers are subjected to heat treatment of dipping in a boiling water for 30 minutes and then dried in a hot air dryer at 70C.
  • EXAMPLE 3 The animal hair-like fibers obtained in Example 1 were mixed with other conventional acrylic fibers in the proportion as shown in Table 3.
  • ' M can value
  • a conventional spinning oil for acrylic fibers was applied to the mixed fibers and the oiled fibers were set to a roller card to provide a uniform sliver having a weight of l5g./meter.
  • the sliver was woven into a knitting fabric by a sliver knitting machine to give a pile fabric.
  • the particulars of the knitting fablic employed are as follows:
  • Knitting yarn spinning yarn of acrylic fiber yarn count ZOS (English cotton yarn count); 2 ends doubling Course: 23/254 mm.
  • pile fabric was backed with acrylic resin. After heat set in a pin tenter dryer, the removing or remaining crimps and the polishing finish were carried out by employing an electric polisher to give a pile fabric.
  • the pile fabric has a hand touchness and appearance similar to natural furs, and concerning the delicate change of lie of the piles thereof a good result was also obtained.
  • FIGS. 1, 2 and 3 are those showing the order of qualities. 1 is superior to 2 and 2 is superior to 3.
  • EXAMPLE 4 The animal hair-like fibers obtained in Example 2 were mixed with other conventional acrylic fibers in the proportion as shown in Table 5.
