The present invention relates to a method of manufacturing a damp proof fabric and a damp proof fabric produced by the damping method, and more particularly, to a method of manufacturing a damp proof fabric capable of minimizing voids between filaments and exhibiting excellent damp proof property even without post- Lt; RTI ID = 0.0 > fabric. ≪ / RTI >
For example, nylon fabrics having a lightweight, high density and flexibility are desired in down-proof fabrics used in down jackets, bedding, etc., in order to obtain higher thermal insulation. When such a nylon fabric is used, a warm-keeping material excellent in thermal insulation can be obtained. Further, since the fabric is flexible, the down jacket, the cotton used as a heat insulating material of the bedding, feathers and the like are not excessively compressed by the down-proof fabric, so the air retention rate can be increased. By such an action, a further excellent heat insulating power can be obtained.
Recently, as the demand for outdoor products has increased rapidly, a variety of textile products for outdoor use having various functions have been developed. In particular, down-proof fabrics used for outdoor use among outdoor textile products have recently become lightweight.
Currently down fabric is used for down jacket, bedding, etc. In addition to the outer cloth, the down cover is used as a lining fabric for the inside of the outer cover to prevent the hair from coming out. However, in order to meet the recent trend of lighter weight, it is required to develop a very lightweight down-proof fabric that does not leak hair using only outer material.
Down Proof The fabric used for lightweight fabrics is made of nylon 20 denier grade fabric with the use of a lining fabric for down cover or a polyurethane or silicone coating However, such coated fabrics have disadvantages that the duck hairs can be damaged quickly due to insufficient functionalities such as air permeability and moisture permeability, and there is a disadvantage in that the soft feeling can not be obtained .
For example, Korean Patent Laid-Open Publication No. 2015-0109662 discloses a DTY yarn that is draw-textured using a side-by-side composite yarn of nylon 66 and a shrinking nylon 6 as yarn, and has an oblique density of 250 to 270 yarns / Discloses a method of manufacturing a down-proof fabric by weaving with a fiber / water-repellent agent in an amount of 50 to 60% by weight. However, according to such a method, there is a problem in that the production cost is high due to the composite spinning process, the production of a badge fabric is difficult, and a water-repellent coating process is further required, thereby lowering productivity and cost competitiveness.
It is an object of the present invention to overcome the problems of the prior art described above, and it is an object of the present invention to provide a method of manufacturing a down-proof, perforated fabric capable of expressing a specific gloss and touch sensation while forming a fabric without forming a post- And to provide a down-proof laminated fabric produced thereby.
One aspect of the present invention to attain the above object is to provide a yarn having a cross-sectional shape of a short fiber of Y-shape, a deviation of 3.0 to 10.0 and a fineness of 20 to 40 denier, Characterized in that the fabric is weaved at a density of 140 to 200 T inclined and 140 to 200 T of weft.
Another aspect of the present invention to attain the above object is to provide a yarn having a cross-sectional shape of a Y-shape, a deviation of 3.0 to 10.0 and a fineness of 20 to 40 denier, Characterized in that the fabric is woven with a density of between 140 and 200 T inclined and between 140 and 200 T by weft.
Another aspect of the present invention relates to a heat insulating material comprising a cover made of a nylon fabric made of a down-proof fabric and a heat insulating material filled in the cover.
According to the downstream fabric of various embodiments of the present invention, the fabric is designed from yarns of a high Y-shaped cross-section so as to minimize pores between the filaments, thereby enabling the fabrics to exhibit excellent durability without the post- It is possible to provide a down-proof fabric in which a specific gloss and touch feeling are exhibited by the cross-sectional shape.
According to the present invention, when the post-processing step such as resin coating is omitted, the production cost can be reduced and the productivity can be improved, and the durability of the down-proof fabric can be improved. It is possible to provide a down-proof fabric excellent in warmth.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a photograph of a modified cross-section yarn used in the manufacture of a down-proof fabric of an embodiment of the present invention.
Fig. 2 is a cross-sectional schematic diagram for explaining the cross-sectional shape of the modified cross-section monofilament used for manufacturing the down-proof fabric of the present invention.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
In the present invention, by designing a fabric with a yarn having a high Y-shaped cross section, the gap between the filaments is minimized, so that it is possible to manifest an excellent down-proof property as a fabric itself without having to go through post-processing such as cloth coating.
In the method of the present invention, the cross-sectional shape of the short fibers is Y-shaped, the degree of deformation is 3.0 to 10.0, the nylon modified cross-section yarn having a fineness of 20 to 40 denier is densified to 20 to 20 denier, 140 to 200 T to produce a down-proof fabric.
The cross-sectional shape of the short fibers of the modified cross-section yarn is Y-shape, and the degree of deformation is 3.0 to 10, preferably 3 to 9, more preferably 4 to 8, most preferably 5 to 7. Here, the Y-shaped cross section means that the cross section is composed of three leaf tops. For example, as shown in Figs. 1 and 2, the Y-shaped cross section refers to the cross-sectional shape of the
The nylon modified cross-section yarn has a ratio (c / d) of the length (c) from the center of the inscribed circle to the upper end of the blade to the width (d) of the upper portion of the leaf in the range of 1.10 to 5.0. If the ratio (c / d) of the length (c) from the center of the inscribed circle to the upper end of the leaf to the width (d) of the upper part of the leaf is less than 1.10, the effect of reducing inter- filament voids is insufficient, And when it exceeds 5.0, the radioactivity may become poor.
The nylon raw yarn used in the present invention may be nylon 6, nylon 66, nylon 610 and nylon 56, and particularly preferably nylon 6 or nylon 66. Further, as long as the effect of the present invention is not impaired, these polymers may contain a copolymerization component. Examples of the copolymerization component include ε-capramide, tetramethylene azepamide, hexamethylene sebacamide, tetramethylene isophthalamide and tetramethylene terephthalamide.
The fineness of the short fibers of the modified cross-section yarn is preferably not less than 20 denier and not more than 40 denier. If the fineness of the fibers is less than 20 deniers, a sense of coolness that comes from a proper fit can not be obtained. If the fiber has a fineness of more than 40 deniers, the feel of the fabric becomes uneven, and it becomes rough and hard. The fineness of the short fibers is more preferably from 30 denier to 40 denier. The gloss of the short fibers is 50 to 75.
Weaving is performed at a high density with an oblique density of 140 to 200 T and a weft density of 140 to 200 T. The nylon fiber of the present invention may be applied to various tissues derived from these, including plain weave, twill weave, main weave weave, and the like. The abrasion resistance is particularly excellent due to the wear durability effect caused by the abrasion resistance.
Pretreatment at 90 ~ 95 ℃ to improve penetration and dyeing. Dyeing is done with usual acid dye. After dyeing, it may be dipped in silicone softener to improve tear strength.
The fabric of the present invention can be subjected to refining, dyeing, and finishing by a conventional method, and the type of finishing agent is appropriately selected depending on the use of the nylon fiber used. However, as described above, it is not preferable to treat at a temperature higher than the treatment temperature in the thermal relaxation process in a tense state because it impairs heat relaxation effect. In addition, calender processing is highly desirable because it also has an effect of increasing crystallinity.
The nylon fabric is calendered, and preferably has a tear strength of 7 N or more and an air permeability of 1.0 to 1.2 cc /
Another aspect of the present invention is a down-proof fabric characterized in that it is comprised of the nylon fabric. The down-proof fabric of the present invention is composed of a nylon cross-section yarn having a cross-sectional shape of a Y-shaped cross section, a degree of deformation of 3.0 to 10.0 and a fineness of 20 to 40 denier, 200T, and weft 140-100T. The down-proof fabric has a tear strength of 7N or more and an air permeability of 1.0 to 1.2 cc / cm < 2 > / sec or less.
Another aspect of the present invention is a heat insulating material characterized by comprising a cover made of the down-pr? G-woven fabric and a heat insulating material filled in the cover. In general, when the fabric is provided with various functions in the post-processing, there is a problem that the function is deteriorated by repetition of wearing or washing. However, the fabric of the present invention has a problem that the function imparted by the above- It has excellent persistence of proof property.
According to the present invention, it is possible to obtain a nylon fabric which is lightweight and excellent in tear strength. The nylon fabric of the present invention can be suitably used for a warming material such as a down jacket or a down quilt because it is excellent in warmth and down-proof property and excellent in gloss and touch feeling.
Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.
Example One
The yarn was weaved in an air jet loom in a plain weave with a warp density of 170T and a weft density of 170T by using a 24 filament nylon type cross-section yarn having a cross-sectional shape of a short fiber of Y shape, a separation degree of 2.5 and a fineness of 20 denier After that, the fabric was pretreated at 80 ° C, dyed with a Rapid dyeing machine, and calendered at a temperature of 170 ° C to prepare a down-proof fabric. The physical properties of the fabrics are shown in Table 1 below
Example 2 to 6 and Comparative Example 1 to 8
As shown in Tables 1 to 3, experiments were performed in the same manner as in Example 1 while varying the release profile, the fineness, the warp density, and the latitude density to produce a fabric. The physical properties of the thus-prepared stretched yarn were evaluated and are shown together in Tables 1 to 3 below.

[Property evaluation method]
The method for evaluating the physical properties of the down-proof fabric obtained in the examples of the present invention was evaluated by the following methods.
○ The degree of heterogeneity was evaluated by the diameter of the circumscribed circle (b) / the diameter of the inscribed circle (a).
Tear strength measurement method: ASTM D2261-13, C.R.E.
○ Air permeability: It was evaluated by KS K ISO 9237: 2011.
Down-proof property: KS K 0822: 2012, evaluated as feather-wool permeability by tumbling method. Feathers 60%, fluffy 40%
○ Glossiness: Gloss is highly dependent on visual evaluation. It is not good to shine a lot, not bad because it is not glossy. However, when Y-shaped cross-section is made, it means that it has differentiated shine compared to the existing fabric.
As can be seen from the above Table 1, the down-proof fabric of the present invention is capable of exhibiting excellent down-proofness, gloss and touch feeling without the necessity of post-processing such as fabric coating.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Anyone who can afford it will know. Therefore, the true scope of protection of the present invention should be defined by the following claims.
