Problems solved by technology

However, in these proposals, since the entire fabric is heated at a temperature higher than the melting point of the above-mentioned low-melting fiber, the entire texture or pile fibers are also fused, and there is a problem of rough texture.

Embodiment

[0049] The present invention will be specifically described below through examples. In addition, this invention is not limited to the following Example.

[0050]

[0051] 1. Hair loss

[0052]Apply a load of 600g (14.3kg / cm 2 ) with a fixed load of 30cm in width, while rubbing the surface of the fleece fabric 10 times in the direction of the fleece and 10 times in the opposite direction, using the adhesive tape to recover the fluff. 2 Convert the weight to get the amount of hair shedding.

[0053] 2. Hair loss evaluation

[0054] Based on the amount of hair loss, evaluation was performed on a scale of 4 levels as shown below.

[0055] A: 0.3g / m 2 below (very good grade)

[0056] B: More than 0.3g / m 2 And at 0.6g / m 2 below (good grade)

[0057] C: More than 0.6g / m 2 And at 1.0g / m 2 Below (not so good grade)

[0058] D: More than 1.0g / m 2 (bad level)

[0059] 3. Softening point

[0060] Fibers of 1 g each used in the following manufacturing examples were opened,...

manufacture example 1～30）

[0099] Among production examples 1 to 30, production examples 1, 7, 13, 19, 23, and 27 are comparative examples, and the other production examples are examples. Using a top-fed pile knitting machine (circular knitting machine) for making artificial fur, use the above-mentioned polyester fiber as a ground yarn, and supply pile fiber yarns composed of acrylic fibers shown in Table 1 below. Strips (10-14g / m) were used to weave the pile fibers of Production Examples 1-30. The number of loops in the columns of the ground weave is 16 to 17 per inch, the number of loops in the courses is 22 to 33 per inch, and the others are the conditions shown in Table 1 below. Next, a backing resin is impregnated into the back surface of the fleece. As the backing resin, use emulsified copolymer latex with acrylate as the main component, and as an aqueous solution (emulsion) with a latex concentration of 40wt%, impregnate and adhere to 25g / m of the example product in terms of resin solid content ...

manufacture example 31～40）

[0102]Production Examples 31 to 35 were obtained in the same manner as in Production Examples 1 to 30, except that the pile fiber sliver composed of acrylic fibers shown in Table 2 below was used, and the contact heating and pressure treatment was carried out under the conditions shown in Table 2 below. fleece cloth. In addition, in addition to adopting the above-mentioned kapok yarn as the ground yarn, adopting the pile fiber yarn sliver made of acrylic fiber shown in the following table 2 and carrying out the contact heating and pressure treatment under the conditions shown in the following table 2, the same as in the production example 1 -30 The fleece fabrics of Production Examples 36-40 were obtained in the same manner. Production examples 31 to 35 use the same pile fibers and ground yarns. Production example 31 is a comparative example without contact heating and pressure treatment, and production examples 32 to 34 are prepared at a predetermined temperature lower than t...

Abstract

A pile fabric in which specific areas only have been fusion-bonded and the pile fibers are thereby prevented from falling off, without impairing the texture; and a process for producing the pile fabric. The pile fabric (5) comprises a ground weave and pile fibers (2) twisted around the ground yarns (1) that constitute the ground weave and rising on the front surface of the ground weave, wherein the pile fibers (2) are fibers of at least one kind selected from a group consisting of acrylic fibers and modacrylic fibers, the pile fibers (2) have a lower softening point than the fibers constituting the ground weave, and among the pile fibers (2) twisted around the ground yarns (1) constituting the ground weave, at least some of the pile fibers (2) located outside the ground yarns (1) constituting the ground weave have been fusion-bonded and the pile fibers (2); rising on the front surface of the ground weave have not been fusion-bonded. The process for pile fabric production involves the step of conducting contact heating / pressing from the back side of the ground weave at a temperature which is equal to or higher than the softening point of the pile fibers (2) but is less than the softening point of the fibers constituting the ground weave.

Description

technical field [0001] The present invention relates to a pile fabric in which pile fibers are prevented from falling out, and a method for producing the same. Background technique [0002] Conventional fleece fabrics are known as fur-like fabrics under names such as faux fur, artificial fur, and boas. They are made of fleece, fleece. When weaving the pile, it is mainly knitted with a sealed circular rib knitting machine and a sliver feeding type plush knitting machine (sliver knitting, circular knitting machine), all of which are cut pile. When knitting with the double raschel warp knitting machine of the warp knitting machine, the ground weave is double formed, the connecting thread is wound between the ground weaves, and the middle of the connecting thread is cut to knit. In the weaving method, use a pile loom or a short-pile loom to wind the upper and lower ground fabrics with a connecting thread between them, cut off the upper and lower base fabrics with a knife, and ...
