Abstract

The present invention relates to a method of producing an air texture having excellent feel and stretch property by using an effective Saro Rayon filament yarn and entangling in an air texturing device by using a polyester based latent crimping filament yarn As a result, according to the present invention, it is possible to provide an eco-friendly stretchable composite yarn excellent in the strength of elongation even without using spandex fiber by combining rayon of natural material and latent fiber of functional material.

Description

TECHNICAL FIELD [0001] The present invention relates to a process for producing airtextured yarn havings excellent natural-feeling and stretch property,

The present invention relates to a method of producing an air texture having excellent feel and stretch property by using an effective Saro Rayon filament yarn and entangling in an air texturing device by using a polyester based latent crimping filament yarn will be.

In the well-being era, the use of natural fibers is increasing in the textile industry as an item for children's market and silver generation. Along with this tendency, along with various functionalities of synthetic fibers, it is demanded that synthetic fibers have environment-friendly and human-friendly functions such as natural fibers. In addition, attempts to blend or blend synthetic fibers with natural fibers have been actively pursued.

Rayon is a typical synthetic fiber of cellulose fiber, which is made from regenerated cellulose, which is not more than 15% bicyclic, and is widely used for high-quality fibers due to its inherent gloss, specific gravity, and feel. Such rayon has a disadvantage in that it has no static electricity and has good cooling sensation when worn, but it has a disadvantage in that it shrinks weakly due to moisture and damages the cloth well, and its application range is limited.

In order to overcome the disadvantages of the rayon and to secure various functionalities, in order to apply synthetic fibers such as nylon or polyester, Korean Patent Laid-Open Publication No. 10-2002-0088855 discloses a method of producing a low-shrink polyester partial stretching yarn and a high-shrinkage cellulose diacetate yarn , And this shrinkage effect is provided by this shrinkage filament yarn to produce excellent stretchability, softness, and drape. However, the process of converting cellulose diacetate into rayon fiber by a saponification process by alkali treatment after fabric production need.

Korean Patent Publication No. 10-2002-0088855 (published on Nov. 29, 2002)

Therefore, according to the present invention, it is an object of the present invention to provide an environmentally friendly stretchable composite yarn excellent in strength and strength without spandex fiber by combining rayon natural material and latent capacity fiber as a functional material.

Therefore, according to the present invention, rayon filament yarn is supplied as an effect yarn to the air texturing apparatus while passing over the first effect feed first roller and the effect use second feed roller while giving an overfeed of 10-30%

The polyester-based latent crimping filament yarn is inspected and fed to the air texturing apparatus while passing through the judging feed roller,

The effect yarn and the examination supplied together with the air texturing apparatus are entangled in an air texturing apparatus having an air pressure of 10 to 12 bar and a heater temperature of 160 to 190 ° C., passed through a heater, passed through a delivery roller, / min. The production method of the air texture work excellent in the feeling of natural material and stretchability is provided.

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

The air texture having excellent feel and stretch property of the natural material of the present invention can be manufactured by using a Saro Rayon filament yarn and entangling in an air texturing device using a polyester-based latent crimping filament yarn as a judging yarn.

1, a rayon filament yarn is passed through an effect using first feed roller 3 as an effect yarn 1, and then an effect using second feed roller 5, And the polyester based latent crimping filament yarn is passed through the judging solvent 1 feed roller 6 and the judging solvent 2 feed roller 7 while passing through the air texturing device 8 8, and after the effect yarn and the examination supplied together with the air texturing apparatus are entangled in the air texturing apparatus, the third feed roller 9, the fourth feed roller 10 and the heater 11 are passed Passed through the delivery roller 12 and wound at a speed of 300 to 500 m / min. In the present invention, the hot pin is not passed.

The rayon filament yarn is imparted with an overfeed of 10 to 30% while passing through the first feed roller for effect use and the second feed roller for effect use, thereby imparting soft physical properties to the natural material. When the overfeed rate is less than 10% And a slab may be generated when the overfeed rate is over 30%.

In the present invention, the yarn of the yarn of the present invention has a single yarn fineness of 2 to 6 dpf rayon filament yarn, and the polyester based latent crimping filament yarn is a composite yarn of the polyethylene terephthalate and polytrimethylene terephthalate combined side by side Use of a yarn having a single yarn fineness of 2 to 6 dpf is superior to other yarn materials in terms of melanchthony tone expression, natural touch expression and stretching characteristics, yarn strength and recovery rate characteristics of the final air texture yarn.

 In the present invention, the air pressure of the air texturing apparatus is preferably 10 to 12 bar and the heater temperature is preferably 160 to 190 ° C. If the air pressure is less than 10 bar, the loop formation may be insufficient. When the bar pressure exceeds 12 bar, Problems may arise.

Therefore, according to the present invention, it is possible to provide an eco-friendly stretchable composite yarn excellent in strength and strength without using spandex fiber by combining rayon natural material and latent housing, which is a functional material, It is possible to provide a material that can further increase its value.

1 is a side view of a construction of an air texture of the present invention,
Fig. 2 is a schematic diagram of a manufacturing process of an air texture of the present invention,
3 and 4 are test reports of the air texture of the present invention.

In the following examples, the air texture of the present invention having excellent feel and stretchability of natural materials is used as a non-limiting example for producing a construction.

[Example 1]

Using the 60D / 24F rayon filament yarn as an effect yarn, the yarn is fed to the air texturing device while the overfeed 15% is fed through the first feed roller and the second use feed roller, and 50D / 24F polyester latent crimp filament yarn The air texture was fed into the air texturing apparatus while passing through the examination feed roller, and then entangled at an air pressure of 12 bar, passed through a heater at 190 ° C., passed through a delivery roller, and wound at 450 m / min. The properties of the fabricated fabrics were measured and are shown in Table 1 below.
