Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-textured yarn having excellent sweat-absorbing and drying properties,

The present invention relates to an air-textured yarn excellent in sweat-absorbent quick drying property and stretchability and a method for producing the same.

Recently, sports / casual wear has been developed with a variety of lightweight warmth and cold feeling materials for external environment by global warming measures while various functional products are pouring. In addition to these functionalities, the comfort of clothes in the psychological and sensory comfort, convenience, and health and safety has been emphasized in response to new demands for comfort.

The major factors of this comfort are not only the temperature, humidity, and airflow of the micro-space between clothing and skin, but also the clothing pressure (comfort) Do.

In order to satisfy the comfort of the clothes, development of a stretch material has been actively carried out in order to improve the feeling of contact between clothing and skin, which is the pressing force of the clothes, which is the pressing force that the skin receives from the clothes.

In general, synthetic fibers have been mainly used to impart elasticity. In recent years, natural products have been preferred in accordance with environment-friendly product trends. Thus, the elasticity of various materials such as cotton, rayon, However, in comparison with synthetic fibers, the elasticity is not sufficiently manifested and the use thereof as a stretchable material has not been commercialized.

Spandex, the most widely used synthetic material to give elasticity to apparel products, is most widely used because of its high elasticity and unique elasticity. As a typical method, a core is made of spandex and a staple fiber such as a synthetic fiber is covered with a spiral structure in a covering machine, but a twist number suitable for tension fluctuation and number of turns due to the spindle speed There is a problem in the weaving. Further, there is a problem of environmental pollution in the manufacturing process, deterioration of physical properties in a high-temperature and high-pressure process, and defective dyeing. In the case of such a spandex covering fabric, even if a hollow fiber of light insulation is applied together, the effect of light insulation can not be exhibited due to the weight of the spandex.

Therefore, it is possible to solve the disadvantages of the spandex covering fabric and solve the problem of poor staining unique to spandex and lowering the touch feeling upon contact with the human body, overcome the weight of the spandex to achieve lightweight insulation, and exhibit a composite function of stretching, It is necessary to develop possible materials.

In order to improve the elasticity, the development and the demand of the pottery housing have been increasing recently. The pottery housing is soft as a new and contraction material which utilizes the inherent potential of the potential crimp even though the crimper is not separately provided It has been developed for a variety of clothes applications because of its excellent stretch and feel. Korean Patent Application No. 10-2003- 0070187 discloses a polyester-based stretchable polyester yarn characterized by using a side-by-side PTT / PET latent shear composite yarn as a core yarn and partially oriented PET microfibers as a sheath yarn The present invention provides a composite warp yarn, which not only exhibits a high degree of stretchability but also exhibits a composite warp yarn excellent in dyability, soft touch feeling and workability. However, it is difficult to exhibit a cold effect when used alone, There is a difficult problem in setting the condition in the step.

In the case of the material for cold sensation development, sweat-absorbing quick-drying yarn is mainly developed, and its shape is mainly composed of a deformed cross-section yarn. The sweat-absorbing quick drying yarn is an important functional material for comfort in recent years, and it imparts comfort by expressing the function of quickly releasing the sweat generated in the human body by the capillary between yarns formed at the time of weaving. These materials may be applied to weaving alone, or may be used in combination with other materials by yarn processing techniques such as twisting, interlacing, and the like, but they have not achieved sufficient results in terms of stretchability.

Therefore, it is an object of the present invention to overcome the disadvantages of the prior art and to develop a clothing product which satisfies all the aspects of activity, functionality, and design and exhibits an optimal comfort, It is an object of the present invention to provide a composite yarn which can overcome the deterioration of touch feeling and overcome the weight of spandex to provide a lightweight, sweat-absorbent quick-drying functional material.

Therefore, according to the present invention, the polyester based latent crimping filament is supplied at an overfeeding rate of 13 to 17% and the polyester cross-section filament is supplied at an overfeeding rate of 20 to 24% Characterized in that it is air-textured at an air pressure of 9 to 11 kg / cm 2, passed through a heater of 180 ° C to 200 ° C for heat treatment, and then wound at a speed of 400-450 m / min. / RTI >

Hereinafter, the present invention will be described in more detail.

The present invention relates to a method for producing an air-textured processed yarn for producing loops on a surface of a yarn by injecting high-pressure air in a diagonal direction through a polyester-based latent crimping filament-polyester polyester cross-section filament through an air- According to the invention, it is possible to provide an air-texture processing yarn excellent in quick-drying property and stretchability sucked.

The manufacturing method of the air texture yarn of the present invention largely consists of the inspection and supply of superfine yarn, the air texture, the heat treatment and the winding step.

First, the polyester based latent crimping filament is supplied at an overfeeding rate of 13 to 17% by examination. When the overfeeding rate is less than 13%, the strength of the obtained air-textured yarn is increased, but the elongation is decreased. There is a problem that the strength is lowered and the fineness is increased and the thread is thickened.

On the other hand, when the overfeed rate is less than 20%, the strength of the obtained air-textured yarn is increased, but the loof appearance is decreased, and when 24% There is a problem in that the strength is lowered and the irregular loops are much developed when the amount is exceeded, thereby deteriorating the quality of the air textured yarn.

In the present invention, the polyester-based latent crimping filament supplied in the present invention has a fineness of 70d / 24fila to 75d / 36fila and a heat shrinkage of 15 to 20%, a B-force of 275 to 282cN, an elongation of 25 to 28% and a strength of 3.5 to 3.8gf / d polyethylene terephthalate / polytrimethylene terephthalate side by side composite siderite,

The cross-section polyester filaments supplied as superfine yarns were polyester cross-section filaments having a fineness of 50 d / 36 fila to 75 d / 72 filament, B-force of 351.5 to 353.4 cN, elongation of 27.6 to 28.9% and strength of 4.6 to 4.8 gf / Strength improvement of texture yarn, excellent elongation, cold sensation by sweat fast drying, and loof expression.

Thereafter, the above-mentioned examination and surveillance are supplied together with the air texture nozzle to form air texture yarn at an air pressure of 9 to 11 kg / cm 2. If the air pressure is less than 9 kg / cm < 2 >, the interlocking is not completely performed and uneven loops can be generated. When the air pressure exceeds 11 kg / cm < 2 >

If the diameter of the air texture nozzle is less than 1.2 mm, the strength of the obtained air-textured yarn is increased, but the elongation is decreased and the rate of change in the number of luxations is increased. There is a problem that irregular loops increase.

If the examination ratio is less than 45%, the strength of the air-textured yarn may be lowered and the elongation may become too high, resulting in a 55% If it exceeds, the strength is increased, but the elongation may become too low.

After the air-texture post-composite yarn is passed through a heater at 180 ° C to 200 ° C and heat-treated, the air-textured yarn of the present invention is manufactured by winding at a speed of 400-450 m / min. If the temperature is lower than 180 ° C, there is a problem that the thermal stability is not maintained and the bulky property is not maintained. If the temperature exceeds 200 ° C, a problem of property deterioration may occur. In the case of less than 400 m / min, the productivity is lowered. In the case of exceeding 450 m / min, the strength of the air-textured yarn obtained by the infiltration of the air- .

According to the present invention, an air-textured yarn having a fineness of 169.4 d / 108fila to 170.9 d / 108fila, a B-force of 509.5 to 510.2 cN, an elongation of 21 to 24%, a contraction ratio of 14 to 18% and a strength of 2.7 to 3.0 gf / , Excellent sweat-absorbing quick-drying property, excellent in feel due to Loop expression, and improved in elongation.

Therefore, according to the present invention, it is possible to overcome the weight loss of spandex by solving the problem of poor staining unique to spandex and deterioration of touch at the time of contact with human body, thereby achieving excellent light fastness and sweat fastness. To provide a composite yarn that satisfies all aspects of activity, functionality, and design, and can produce an apparel product that exhibits an optimal comfort.
