DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a mall yarn using polyamide fibers as napped yarn, which is suitable for the production of napped fur fabric having a soft texture.

[0002]

2. Description of the Related Art A mall yarn comprising a core yarn, a core holding yarn, and a flower yarn is a yarn in which the hair yarn sandwiched between the core yarn and the core holding yarn has become a nap. Various kinds of fibers such as synthetic fibers and natural fibers are used. For example, a spun yarn or a filament yarn made of polyester fiber, acrylic fiber, or the like is used.

[0003] In addition, the covering property of the yarn is improved by forming the yarn from an extremely thin crimped fiber or a latently crimpable conjugate fiber, for example, an extremely thin crimped yarn having a single yarn of 0.5 dtex or less. Japanese Patent Application Laid-Open Nos. 59-112046, 59-36684, and the like have proposed that a high-grade mall yarn having a soft touch and feel be manufactured.

[0004]

However, in these conventional methods, easily splittable composite fiber yarns are used for the yarns for the yarns, and the yarns for the yarns are formed into molding yarns. It only discloses specifically forming, and does not specifically disclose the case where the polyamide fiber is used as a nap.

Accordingly, an object of the present invention is to provide a method for producing a mall yarn suitable for napkin fur-like fabrics such as suede and buckskin using polyamide fibers as napkin. That is, an object of the present invention is to provide a method for producing a mall yarn that can be densely covered with nap of soft polyamide fiber, and can be used as a nap fur fur fabric having a soft, light, and soft feel.

[0006]

In order to achieve this object, the method of the present invention uses a core yarn, a core holding yarn, a heat-fusible fiber along with the core yarn, and a yarn. In the method for producing a molding yarn, a crimped polyamide filament yarn is used as a core yarn and / or a core-suppressing yarn, and an indented crimped filament yarn is used as a yarn for a flower yarn. The problem was solved by forming a raw yarn and then performing a heat treatment to cause fusion by the heat-fusible fiber.

In the production method of the present invention, first, it is necessary to use an indented crimped filament yarn as a yarn for a flower yarn. This indented crimped filament yarn (hereinafter abbreviated as “indented crimped yarn”) is a filament made of a polymer which can be indented and crimped like polyamide such as nylon 6 or nylon 66, polyacrylonitrile, rayon or polyester. Yarn is obtained by stuffing in the usual manner, for example, “River Loft” (Kawabo Rivers Co., Ltd.) or “Shintron”
(Manufactured by Taisei Synthetic Fiber Co., Ltd.). According to the indentation crimping process, a crimped yarn suitable for a flower yarn can be easily produced from a very fine single yarn.

[0008] Among these polymers, polyamide fibers are excellent in prevention of falling out of the yarn, resistance to sagging, etc., and therefore, the yarn is made of only a polyamide indented crimped yarn or
It is preferable to use a polyamide indented crimped yarn as a main component, and other indented crimped yarns in combination and mixed. The single-fiber fineness is not particularly limited, but is generally about 0.4 to 12 denier, and the yarn fineness is generally about 50 to 280 denier.

[0009] As described above, the indented crimped filament yarn is the most suitable among the crimped yarns, because the degree of crimping is relatively small and the torque is non-torque. On the other hand, other crimped fibers, for example, false twisted woolly yarn, have strong crimping and torque, and although they have excellent prevention properties of dropping out of the yarn, the yarn becomes shrunk in the maul yarn. However, the texture becomes hard, and even if the cut length of the yarn is changed, the change does not appear and the texture becomes similar, so that the object of the present invention cannot be achieved.

[0010] Further, it is necessary to use a polyamide crimped yarn as the core yarn and / or the core-suppressing yarn, and further use a heat-fusible fiber along these lines. The polyamide crimped yarn may be a processed yarn obtained by indentation crimping, or may be another type of processed yarn, for example, a false twisted yarn, a rubbed yarn, a shaped yarn, an asymmetrically heated or asymmetrical yarn. The latently crimped yarn by cooling may be used. Among them, the crimp elongation rate is 70
A crimped yarn having a relatively small degree of crimp such as about 120% is preferred.

The polyamide crimped yarn may be used for at least one of a core yarn and a core holding yarn, but it is more preferable to use both. The thickness of the core yarn and the core holding yarn is not particularly limited. Therefore 150-280
Although it may be thicker than denier, a thin yarn which is difficult to use with spun yarn, for example, a thin yarn such as 30 denier can be used.

As the heat-sealing fiber used along the crimped yarn, a low-melting polyamide fiber may be used, for example, "Elder" (manufactured by Toray Industries, Inc.).

[0013] The production of the molding raw yarn using the core yarn, the core holding yarn, the flower yarn, and the heat fusion fiber is performed by inserting a predetermined length of a yarn for a flower yarn between the core yarn and the core pressing yarn. The method may be carried out by a conventional method of sandwiching the yarn, cutting the yarn for the flower yarn, twisting the core yarn and the core holding yarn, and winding up.

[0014] The feeling and feel of the obtained fabric using the mall yarn varies depending on the fineness and crimping characteristics of the yarn, but in particular, greatly varies depending on the cut length of the yarn.
For example, in the case of suede tone or corduroy tone, the cut thread length is preferably about 0.5 to 5 mm. If the cut length is longer than that, a backskin-like or mink-like fabric with long raised hairs is obtained.

The obtained raw yarn may be subjected to a wet heat treatment or a dry heat treatment by an ordinary method in order to cause fusion by the heat fusion fiber. The fusion-bonded mall yarn can be converted into a desired raised fur-like fabric product through processes such as knitting, weaving, and dyeing.

[0016]

According to the present invention, an indented and crimped polyamide yarn is used as the yarn for the flower yarn, and a polyamide crimped yarn is used as the core yarn and / or the core holding yarn. It can be a mulled yarn, having a bulky, soft, polyamide fiber densely arranged as a yarn. As a result, it is possible to obtain a mall yarn product which has a soft and soft feel due to the crimped polyamide fiber and has a nap fur-like touch appearance.

On the other hand, in a false twisted yarn having a strong crimp,
The yarns in the obtained mall yarn are in a contracted state, and the texture is a hard yarn.

Further, in the present invention, since the polyamide crimped yarn is used as the core yarn and / or the core-suppressing yarn, it is excellent in fusion with the heat-fused fiber, and the prevention of falling off of the flower yarn is improved.
A mall yarn with excellent durability can be obtained. Further, the core yarn and the core holding yarn can be made thinner, so that the count of the yarn can be reduced.

As described above, according to the production method of the present invention, a non-conventional napping cloth, which is a napping fur-like mall yarn made of napping polyamide fibers, can be obtained. Also,
In the production method of the present invention, an excellent product using napkin fur-like mulled yarn can be obtained without requiring any special process, for example, an additional process such as a process of dividing the yarn.

[0020]

【Example】

[Example 1] As a core yarn and a core-suppressing yarn, a nylon 6 filament yarn was subjected to an indentation crimping process, and an indented crimped yarn “River Loft” 110 denier 30 filament (manufactured by Kawabo Rivers Co., Ltd.) was used. Using. In addition, nylon 6 indentation crimped yarn “River Loft” 70 denier 98 filament was used as a flower yarn. In addition, "Elder" which is a low melting point polyamide yarn as a heat fusion fiber (Toray Industries, Inc.)
50 denier was used.

The heat-fused fibers were fed into the core yarn and the core-suppressing yarn in a uniform manner, and a raw yarn having a cut yarn length of 2.0 mm was produced by an ordinary method. The obtained raw yarn was turned into a skein, placed in a frame, and subjected to a wet heat treatment at 95 to 105 ° C. for 20 minutes.

When this mall yarn was dyed and flat knitted by an ordinary method, a knitted fabric having a supple, lightweight feeling, high flexibility, a suede-like feel and appearance was obtained.
Moreover, the mulled yarn was excellent in durability against falling off of the yarn, showed a soft touch, was excellent in lightness, and was suitable as a material for clothing, regardless of its thinness, which was equivalent to No. 7.

Example 2 A molding yarn was manufactured in the same manner as in Example 1 except that the cut length of the yarn was 12 mm, and the knitted fabric was further formed. The obtained knitted fabric was a flexible, light, mink-like appearance and texture, and was an excellent fabric.

Comparative Example 1 A molding yarn was produced in the same manner as in Example 1 except that a nylon 6 spun yarn having a count of 1/48 was used as a yarn, and the knitted fabric was further formed. The obtained knitted fabric is
Despite the fact that the yarn is a polyamide fiber, there is no crimping, so there is no soft feel, and the appearance and feel are clearly inferior in terms of standing fur.

Comparative Example 2 As the core yarn and the core holding yarn, 1
Example 1 except that the acrylic spun yarn of No./48 was used.
In the same manner as in the above, a maul yarn was manufactured and further knitted.
Although the surface of the obtained knitted fabric had a soft feeling, the knitted fabric lacked flexibility and stretchability as a whole and had a slightly inferior falling resistance of the yarn.
