Description

[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 mole yarn using polyamide fibers as the napped yarn, which is suitable for producing napped fur-like fabrics having a soft texture.

0002

[Prior Art] Molle yarn, which is composed of a core thread, a core restraining thread, and a filament yarn, is a filament in which the filaments are sandwiched between the core thread and the core restraining thread and become raised. Various fibers such as synthetic fibers and natural fibers are used. For example, spun yarns and filament yarns made of polyester fibers, acrylic fibers, etc. are used.

[0003]Furthermore, by composing the filament with ultra-fine crimped fibers or latent crimp composite fibers, for example extremely thin crimped yarns such as single filaments of 0.5 dtex or less, the covering properties of the filament can be improved. It has been proposed in JP-A-59-112046, JP-B-59-36684, etc. to produce a high-quality molle yarn with a soft touch and texture.

0004

[Problems to be Solved by the Invention] However, in these conventional methods, easily split composite fiber yarn is used as the yarn for the filament, and after making it into a mall yarn, the filament is split into filaments made of ultra-fine crimped polyester fiber. However, it does not specifically disclose the case where the polyamide fiber is used as a napped yarn.

[0005] Therefore, the present invention aims to provide a method for producing a mole yarn suitable for fabrics with a napped fur-like texture such as suede or buckskin-like fabrics using polyamide fibers as napped yarn. That is, the object of the present invention is to provide a method for producing a mole yarn that is densely covered with napped soft polyamide fibers and can be made into a napped fur-like fabric that is supple, light, and soft to the touch.

[0006]

[Means for Solving the Problems] In order to achieve this object, the method of the present invention uses a core yarn, a core restraining yarn, a heat-fusible fiber along these, and a filament. , in a method for producing a mole yarn, using a crimped polyamide filament yarn as a core yarn and/or a core holding yarn,
In addition, the problem was solved by forming a malleable yarn by using a pressed crimped filament yarn as yarn for the filament, and then heat-treating it to cause fusion by the heat-fusible fibers. .

[0007] In the manufacturing method of the present invention, first of all, it is necessary to use a press-crimped filament yarn as the yarn for the filaments. This press-crimped filament yarn (hereinafter abbreviated as press-crimped yarn) is a filament made of a polymer that can be press-crimped, such as polyamide, polyacrylonitrile, rayon, and polyester represented by nylon 6 and nylon 66. It is obtained by stuffing yarn using the usual method, such as "River Loft".
(manufactured by Kawabo Rivers Co., Ltd.) and "Cintron" (manufactured by Daisei Gosen Co., Ltd.). According to this push-crimping process, a crimped yarn suitable for filament can be easily produced even from an extremely fine single yarn.

[0008] Among these polymers, polyamide fibers have excellent properties such as preventing the filaments from falling off and sagging resistance, so the filaments can be made of only polyamide pressed crimped yarns or
It is preferable to use polyamide pressed crimped yarn as the main material, and to use it in combination or with other pressed crimped yarns. The single yarn fineness is not particularly limited, but is generally about 0.4 to 12 deniers, and the yarn fineness is generally about 50 to 280 deniers.

[0009] As described above, push-crimped filament yarn is most suitable among crimped yarns for making filaments because the degree of crimp is relatively small and it is non-torque. On the other hand, other crimped fibers, such as false-twisted woolly yarn, have strong crimps and torque, so they are excellent in preventing the filaments from falling off, but the filaments become compressed inside the mall yarn. The object of the present invention cannot be achieved because the texture becomes hard and even if the cut length of the filament is changed, there is no change and the texture remains the same.

Furthermore, it is necessary to use polyamide crimped yarn as the core yarn and/or core restraining yarn, and to use heat-fusible fibers along with these yarns. The polyamide crimped yarn may be a pressed crimped yarn, or it may be a yarn of other types, such as a false twisted yarn, a rubbed yarn, a shaped yarn, an asymmetric heated yarn or an asymmetric yarn. The yarn may be latently crimped by cooling. Among them, the crimp elongation rate is 70.
A crimped yarn having a relatively small degree of crimp, such as about 120%, is preferred.

[0011] This polyamide crimped yarn may be used as at least one of the core yarn and the core restraining yarn.
It is more preferable to use both. The thickness of the core yarn and core restraining yarn is not particularly limited. Therefore, a thick yarn of about 150 to 280 deniers may be used, but a thin yarn such as 30 deniers, which is difficult to use with spun yarn, can also be used.

The heat-fusible fiber used along the crimped yarn may be a low-melting polyamide fiber, such as "Elder" (manufactured by Toray Industries, Inc.).

[0013] In the production of a molded yarn using these core yarns, core holding yarns, filaments, and heat-fused fibers, a predetermined length of filament yarn is inserted between the core yarn and the core holding yarn. The usual method of sandwiching the threads, cutting the filament threads, twisting the core threads and core holding threads, and winding the threads may be used.

[0014] The texture and feel of the resulting fabric using mole yarns differs depending on the fineness of the threads, crimp characteristics, etc., and in particular, varies considerably depending on the filament cut length. For example, for a suede look or a corduroy look, the filament cut length is preferably about 0.5 to 5 mm. If the cut length is longer than that, the fabric will have a buckskin-like or mink-like feel with long piles.

[0015] The obtained malleable yarn may be subjected to a wet heat treatment or a dry heat treatment in a conventional manner in order to cause fusion by heat-fusible fibers. The fusion-treated mole yarn can be made into a desired napped fur-like fabric product through processes such as knitting, weaving, and dyeing.

[0016]

[Function] In the present invention, press-crimped polyamide yarn is used as the filament yarn, and polyamide crimped yarn is used as the core yarn and/or core holding yarn, so that appropriate crimping can be achieved. It can be made into a molle yarn in which bulky, soft polyamide fibers are densely arranged as filaments. As a result, it is possible to obtain a mole yarn product that is soft to the touch due to the polyamide crimped fibers and has a napped fur-like feel and appearance.

On the other hand, false twisted yarn with strong crimp
The filaments in the obtained molle yarn are in a contracted state, resulting in a molle yarn with a hard texture.

Furthermore, in the present invention, since the polyamide crimped yarn is used as the core yarn and/or the core holding yarn, it has excellent fusion with heat-fusible fibers, improves the ability to prevent filaments from falling off,
A mall yarn with excellent durability can be obtained. Furthermore, it is possible to make the core thread and the core restraining thread thinner, and the thread count of the mole yarn can be reduced.

As described above, according to the production method of the present invention, it is possible to obtain an unprecedented napped fabric, which is a napped fur-like mole yarn fabric in which polyamide fibers are napped. Also,
In the manufacturing method of the present invention, an excellent product using napped fur-like mole yarn can be obtained without requiring any special process, for example, an additional process such as dividing the filament.

[Example 1] As a core yarn and a core holding yarn, a pressed crimped yarn obtained by pressing and crimping nylon 6 filament yarn.
Riverloft" 110 denier 30 filament (manufactured by Kawabo Rivers Co., Ltd.) was used. In addition, nylon 6 pressed crimped yarn "Riverloft" 70 denier 98 was used as the filament.
A filament was used. In addition, "Elder" (manufactured by Toray Industries, Inc.) 50, a low melting point polyamide yarn, is used as a heat-fusible fiber.
Denier was used.

[0021] The heat-fusible fibers were aligned and supplied to the core yarn and the core restraining yarn, and a molded raw yarn with a filament cut length of 2.0 mm was produced by the usual method. The obtained malleable yarn was made into skeins, placed in a frame, and subjected to a moist heat treatment at 95 to 105°C for 20 minutes.

[0022] When this mole yarn was dyed in a conventional manner and plain knitted, a knitted fabric was obtained that was supple, lightweight, highly flexible, and had a suede-like texture and appearance. Moreover, even though the mole yarn was as thin as No. 7, it had excellent durability against filament shedding, had a soft feel, and was lightweight, making it suitable as a material for clothing.

[Example 2] Molle yarn was produced in the same manner as in Example 1, except that the filament cut length was 12 mm, and was further knitted into a knitted fabric. The obtained knitted fabric was supple, light, and had a mink-like appearance and feel, and was an excellent fabric.

[Comparative Example 1] Molle yarn was produced in the same manner as in Example 1 except that nylon 6 spun yarn with a count of 1/48 was used as the filament, and was further made into a knitted fabric. The obtained knitted fabric is
Even though the filaments were polyamide fibers, they were not crimped, so they lacked a soft feel, and were clearly inferior in both appearance and texture, with a raised fur-like appearance.

[Comparative Example 2] As the core yarn and core restraining yarn, 1
/Example 1 except that 48 count acrylic spun yarn was used
Molle yarn was produced in the same manner as above, and it was further made into a knitted fabric. The surface of the obtained knitted fabric had a soft feel, but the knitted fabric as a whole lacked flexibility and stretchability, and the durability against shedding of filaments was somewhat poor.

[0026]

[Effects of the Invention] According to the manufacturing method of the present invention, it is possible to easily produce a mall yarn in which filaments are formed by densely arranging soft, non-torque fibers with crimps. A fabric made from mole yarn with a fur-like feel.
can be obtained easily. In addition, it is possible to produce a mall yarn with improved filament retention and excellent durability. Furthermore, it is possible to make the fineness of the core yarn and the core holding yarn finer, and it is possible to make the yarn count finer for the mole yarn.

Therefore, according to the production method of the present invention. By appropriately combining the fibers used, it is possible to easily produce a mole yarn that can easily produce a wide range of napped fur-like fabrics. Moreover, the mole yarn can be manufactured without the need for any special process.
