[0042]Hereinafter, the present invention will be described more specifically by way of examples. Note that the present invention is not limited to the examples below.
[0043]
[0044]A rubber brush (trade name “prescale mat” 5 mm (particle diameter), length 4 cm, width 10.5 cm, manufactured by FUJIFILM Corporation) was used to rub a front surface of a pile fabric ten times in a forward direction and ten times in a reverse direction of piles with a stroke width of 30 cm while applying a constant load of 600 g (14.3 kg / cm2). Thereafter, fallen pile fibers were collected using an adhesive tape, and the weight was converted into per 1 m2, which was defined as the amount of pile fiber loss.
[0045]2. Evaluation of Pile Fiber Loss
[0046]The pile fiber loss of a pile fabric was ranked on a scale of A to D as below:[0047]A: 0.3 g / m2 or less (very favorable level)[0048]B: More than 0.3 g / m2 and not more than 0.6 g / m2 (favorable level)[0049]C: More than 0.6 g / m2 and not mo...
production examples 1-30
[0086]In Production Examples 1-30, Production Examples 1, 7, 13, 19, 23 and 27 are comparative examples, and the other Production Examples are examples. A sliver knitting machine (circular knitting machine) for manufacturing fake furs was used The above identified polyester fiber yarns were used as the ground yarns. Pile fabrics of Production Examples 1-30 were knitted by supplying pile fiber slivers (10-14 g / m) composed of acrylic-based fibers respectively shown in Table 1 below. The number of loops in the wales of the ground structure was 16-17 / inch, and the number of loops in the course of the ground structure was 22-33 / inch. The other conditions are shown in Table 1 below. Next, back surfaces of the pile fabrics were impregnated with a backing resin. As the backing resin, an emulsion copolymer latex composed mainly of acrylic ester was used. The backing resin was an aqueous solution (emulsified solution) with a latex concentration of 40 wt %. The pile fabrics of the examples and...
production examples 31-40
[0088]Pile fabrics of Production Examples 31-35 were obtained in the same manner as Production Examples 1-30, except that pile fiber slivers composed of acrylic fibers shown in Table 2 below were used, and the contact heating / pressurization treatment was performed under the conditions shown in Table 2 below. Further, pile fabrics of Production Examples 36-40 were obtained in the same manner as Production Examples 1-30, except that the above cotton yarns were used as the ground yarns, pile fiber slivers composed of acrylic fibers shown in Table 2 below were used, and the contact heating / pressurization treatment was performed under the conditions shown in Table 2 below. The same pile fibers and the same ground yarns were used in Production Examples 31-35. Production Example 31 is a comparative example in which the contact heating / pressurization treatment was not performed. Production Examples 32-34 are comparative examples in which the contact heating / pressurization treatment was perf...
