Problems solved by technology

On the other hand, acrylonitrile fibers and modified acrylonitrile fibers cannot straighten due to lack of elasticity, so fleece fabrics using these fibers lack sag-recovery and volume feeling (voluluminousness) in use, Different from natural fur
[0003] Therefore, it has been proposed to use polyester fiber as the pile fiber, but the pile fabric using the polyester fiber is excellent in pile recovery and volume feeling, but if the temperature of the polishing treatment during the pile fabric production is low, The curling of the pile fibers on the surface of the napped fur cannot be fully removed, and the tactility is hard due to the entanglement of the pile fibers, which in turn causes hair cracks, and the touch and appearance are different from natural fur.
In general, the polishing of fleece fabrics using polyester fibers requires a temperature close to 200°C, and it is difficult to use them together with conventionally used acrylic fibers and modacrylic fibers from the viewpoint of heat resistance.

Embodiment 1

[0089]

[0090] Using polyethylene terephthalate (PET) with an intrinsic viscosity (IV value) of 0.65, a spinning machine with a spinning temperature of 290°C, a circular section with a diameter of 0.4mm, and a number of holes of 48 is used through a common spinning machine. The yarn was spun at a speed of 320 m / min, and then drawn by 375% by a hot roll at 80° C. to obtain a drawn yarn. In addition, in PET, 0.3 weight part of titanium oxide was added as a matting agent with respect to 100 weight part of PET. Then, after the drawn filaments are combined to a suitable fineness, they are crimped by preheating at 98°C in a stuffing box type crimper, and in a uniform hot air dryer set at 110°C, at a relaxation rate of Heat treatment for 30 minutes in a relaxed state of 15% or less to obtain a crimped yarn with a single fiber fineness of 3 dtex.

[0091]

[0092] The PET crimped yarn obtained above was cut to 51 mm to obtain a raw yarn for fleece. A sliver is made from 100% of...

Embodiment 2

[0094]

[0095] A crimped yarn having a single fiber fineness of 3 dtex was obtained in the same manner as in Example 1, except that after imparting crimping, it was heat-treated for 30 minutes in a hot air dryer set at 60°C.

[0096]

[0097] A pile fabric was produced in the same manner as in Example 1 except for using the PET crimped yarn obtained above.

Embodiment 3

[0099]

[0100] A crimped yarn having a single fiber fineness of 3 dtex was obtained in the same manner as in Example 1, except that after imparting crimp, it was heat-treated for 30 minutes in a soaking air dryer set at 120°C.

[0101]

[0102] A pile fabric was produced in the same manner as in Example 1 except for using the PET crimped yarn obtained above.

Abstract

The present invention provides a kind of polyester-based fiber, which is a polyester-based fiber with crimps, wherein the polyester-based fiber is hung vertically and the temperature is 90-120° C. under a load of 4 mg / dtex When the dry heat treatment is performed for 60 seconds, the difference between the fiber length of the polyester fiber under a load of 4 mg / dtex after the heat treatment and the fiber length of the polyester fiber under no load after the heat treatment is less than 3%. Thus, it is possible to provide a pile fabric that can impart high curl removal properties to the nap surface portion of the fleece fabric with respect to low-temperature polishing treatment at 90 to 160° C., and can also impart good appearance, nap recovery, and volume to the fleece fabric. Sensitive polyester fibers, fleece fabrics using the same, and their manufacturing methods.

Description

technical field [0001] The present invention relates to a polyester-based fiber capable of imparting excellent crimp removal properties to the napped surface layer portion of a fleece, a fleece using the same, and a method for producing the same. Background technique [0002] Acrylonitrile fibers and / or modified acrylonitrile fibers having a feel and gloss very similar to animal hair have been widely used as pile fibers in pile fabrics (also referred to as nap fabrics) which are artificial fur imitating natural fur. On the other hand, acrylonitrile fibers and modified acrylonitrile fibers cannot straighten due to lack of elasticity, so fleece fabrics using these fibers lack sag-recovery and volume feeling (voluluminousness) in use, It is different from natural fur. [0003] Therefore, it has been proposed to use polyester fiber as the pile fiber, but the pile fabric using the polyester fiber is excellent in pile recovery and volume feeling, but if the temperature of the pol...
