Description

Heat-insulating fabric whose thickness is self-controlled {WARM FABRIC HAVING SELF CONTROL OF THICKNESS}

The present invention relates to a heat-insulating fabric that is used in sports clothing such as athletics and ball sports, the thickness is self-controlled to improve the wearing comfort and sweat-absorbing quick-drying function, improved heat retention, comfort.

In general, the fabric used in clothing absorbs water and adheres to the skin, causing discomfort. In particular, since sports clothing such as athletics and ball games are worn when taking intense sports and activities, fabrics having moisture absorption and quick drying are mainly developed to keep the wearer's body comfortable from the external environment.

The fabric used in the conventional sports clothing is made of a material having excellent moisture permeability or a material having excellent waterproofness, and inside the outer fabric, a certain ventilation gap is formed between the user's skin and the outer skin to prevent mutual contact. It is made by applying mesh fabric to lining.

However, such fabrics can not provide an effective ventilation gap between the outer skin and the wearer's skin when used in practice, and when providing a large amount of secretion such as sweat during wearing, it can not provide the initial intended breathability, as well as the contact between the skin and the skin. Even in the hot summer season, the wearer had to wear while wearing underwear to prevent this.

Recently, a moisture-permeable waterproof fabric using a hydrophilic polyurethane that absorbs the generated moisture to be released to the outside and prevents external moisture from penetrating has been widely used in sports clothing or household clothing.

The moisture-permeable waterproof fabric using the hydrophilic polyurethane is manufactured by laminating, dry and wet methods. Japanese Patent Application Laid-Open No. H3-313581 discloses a polyamino acid-based poly-containing polyamino acid-containing poly-acid containing 0.1% or more of powder. A moisture-proof waterproof fabric prepared by laminating a moisture-permeable film made of urethane to a fabric is described.

The moisture-permeable waterproof fabric using the hydrophilic polyurethane resin has a disadvantage in that water does not pass smoothly due to the hydrophilic property of polyurethane. In addition, in the case of using the organic solvent in the manufacturing process, the dye of the fabric may be released by the organic solvent to cause contamination.

In addition, the moisture-permeable waterproof fabric as described above has a limitation in that the amount of moisture that the hydrophilic polyurethane resin can be breathed, when a large amount of moisture is instantaneously not able to breathe all of them.

In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

As used herein, the terms 'about', 'substantially', and the like, are used at, or in close proximity to, numerical values when manufacturing and material tolerances inherent in the stated meanings are set forth, and an understanding of the present invention may occur. Accurate or absolute figures are used to assist in the prevention of unfair use by unscrupulous infringers.

 1 to 3, as shown in FIGS. 1 to 3, a self-regulating layer 100 in contact with the outside and a moisture transfer layer 200 in contact with the skin are formed of a heat insulating fabric having a self-controlled thickness.

As shown in FIG. 2 and FIG. 3, the magnetic control layer 100 includes a deformation part 110 and a support part 130 so that the deformation part 110 is concave or convex when water is absorbed.

The moisture transfer layer 200 is a fabric that absorbs moisture from the skin and quickly moves to the magnetic control layer 100.

According to the present invention configured as described above, the self-regulating heat-insulating fabric is in the same plane state as the general fabric in the state of FIG. 1 (a) in a dry state, but moisture, such as sweat from the skin, by exercise such as climbing or outdoor activities. When discharged, the moisture transfer layer absorbs moisture, moves to the magnetic control layer, absorbs moisture from the magnetic control layer, and deforms the shape as shown in FIG.

As shown in FIG. 1 (b), the heat-insulating fabric whose thickness is self-controlled as the shape of the present invention is self-controlled and the water transition layer 200 is spaced apart from each other in the shape conversion part to form an air layer, which becomes thick and absorbed. It gives quick drying to dry the moisture quickly and keeps warmth by blocking effect between the outside air and the skin.

The self-controlling layer 100 may be made of only the stretched yarn in the longitudinal direction when the moisture is absorbed, and may be made of a general yarn prepared by mixing one or two or more selected from the stretched yarn and natural fibers, recycled fibers, and synthetic fibers.

As shown in FIGS. 2 and 3, the self-controlling layer includes a deformed part in which an elongated yarn absorbs water and is elongated to cause deformation, and a support part 130 supporting the deformable part 110 to stabilize the shape of the fabric. .

The deformation part 110 is a part made of elongated yarn in the longitudinal direction when water is absorbed, and when it is dried, it has a general flat fabric shape as shown in FIG. 2, but when water is absorbed, the cross-sectional area of the deformation part is expanded and is shown in FIG. 3. As shown, the deformable portion 110 is raised to convexly deform the fabric into a curved shape.

The deformation part 110 may be designed to increase in thickness by being settled and concave to deform the fabric into a curved shape.

When the elongated yarn extending in the longitudinal direction when absorbing the moisture of the deformation part 110 is less than 7% in the longitudinal direction when absorbing moisture, it is not effective because the shape conversion phenomenon of the deformation part is insignificant, so it is preferable to use the one having an absorption elongation of 7% or more. something to do. More preferably, fibers having an elongation of 10% or more are used.

The elongated yarn can be used as long as it is an elongated yarn having an elongation as described above, rayon excellent in water elongation can be used, and a copolymer can also be used. For example, the soft segment may be made of polyoxyethylene glycol and the hard segment may be made of polyether ester made of polybutylene terephthalate.

In addition, when using the synthetic fiber, such as polyether ester for the stretch yarn, it will be most preferable to use a composite yarn for the natural touch and appearance of the fabric.

The composite yarn may be formed by various methods such as a covering yarn, an interlacing textured yarn (ITY), an air textured yarn (ATY), a draw textured yarn (DTY), and the like. There will be.

When the covering yarn is manufactured, synthetic fibers such as polyether esters are used as the screening, and recycled fibers or synthetic fibers are used as winding yarns, thereby improving the touch and appearance of the fabric with the same touch and appearance as natural yarns.

The support part 130 is a part for holding the shape of the deformation part 110 to support the shape of the deformation part 110 and to stabilize the shape of the fabric when the deformation part 110 is deformed, and may form the support part 130 in various ways according to the manufacturing method.

The self-controlling layer may be manufactured by weaving or knitting by using a general yarn manufactured by mixing one or two or more selected from stretched yarn, natural fiber, recycled fiber and synthetic fiber, and using only stretched yarn. It can be manufactured through fabric processing.

When manufactured in the woven or plain weave as described above may be formed by forming a plurality of deformation parts 110 having an arbitrary shape with the elongated yarns and the support yarns 130 or the general yarns and extension yarns surrounding the deformation.

When the self-controlling layer is manufactured by knitting, the stretched yarn forming the deformable portion 110 and the general yarn or the general yarn and the elongated yarn forming the support portion 130 are arranged so that the size and shape of the deformable portion 110, the width of the support portion, etc. are suitable for the design. The magnetic control layer of the present invention can be manufactured.

In addition, when the magnetic control layer is manufactured by weaving, it may be manufactured by weaving in a single layer structure, but may be formed in a multi-woven fabric for shape stability of the fabric.

When weaving and weaving into a multi-woven fabric, it is preferable to form the deformable part 110 as a stretched layer by extension yarns, and to form a support part and a back layer by general yarns or general yarns and elongated yarns.

The size of the deformation part 110 should be adjusted according to the use of the magnetic control layer. However, if the surface area of the deformation part 110 is less than 5 mm 2, the area is small even though the deformation part 110 is raised. When it exceeds the deformation portion 110 is difficult to maintain the shape even if raised, the effect of reducing the contact area is not great and the appearance may fall, so the area of the deformation portion will be most preferably 5 ~ 30 ㎜.

In addition, the general yarn can be used alone natural fibers, regenerated fibers, synthetic fibers, it will be possible to use a mixture of two or more mixed yarns.

The method of manufacturing the self-regulating layer using only the stretched yarn may be performed by weaving or knitting the stretched yarn to manufacture the fabric or knitted fabric, and then, except for the plurality of deformation parts 110 having any shape in which the fabric or knitted fabric is designed, the remaining portions may be removed. The thermal control may be performed by heat-setting to lose the stretching function of the stretched yarn or by curing the stretched yarn to form a support 130 covering the deformation part by coating the cured resin to lose the stretched function of the stretched yarn.

The heat setting may be performed by heating the roller or the mold by forming a roller or a mold having a groove in the shape of an arbitrarily designed deformation part, and heat-setting the coating of the cured resin with a curing resin by laminating or printing. The support 130 of the layer may be formed.

The deformable part 110 may be arbitrarily designed and manufactured, and may be formed in a polygonal shape such as a circle, a triangle, a rectangle, and the like, so that various shapes may be visually exposed on the surface of the fabric when water is absorbed to express an aesthetic effect on the fabric. .

The moisture transfer layer 200 is a layer for quickly moving the moisture absorbed from the skin to the magnetic control layer, and comprises a backing layer 210 in contact with the skin and a bonding layer 230 in contact with the magnetic control layer. It is desirable to form the binding layer at a high density.

In general, moisture is a low density layer to a high density layer, a hydrophobic material having a low process moisture content and a hydrophilic material having a high process water content, and exhibits a characteristic of moving from a small place where the specific surface area of the fiber is large. In other words, the fabric composed of low density, hydrophobic material, and low specific surface area yarn is intended to push out moisture, and the fiber sheet composed of high density, hydrophilic material and high specific surface area yarn is intended to absorb moisture.

Therefore, even when the back layer 210 and the stitching layer 230 are formed of the same material and density, the moisture moves between capillary phenomena between minute gaps of the fabric, but if the back layer is formed at a low density and the stitching layer is formed at a high density, the microcapillary structure is formed. The water transition phenomenon is formed more quickly.

In addition, the back layer 210 is composed of a hydrophobic yarn and the tie layer 230 is composed of a hydrophilic yarn so that the moisture contained in the back layer 210 can be quickly moved to the tie layer 230.

The back layer 210 may be formed of polypropylene-based yarns, and the bonding layer 230 may be formed of polyester yarns or polyamide yarns.

The polypropylene-based yarn is a very hydrophobic fiber having a process water content (water content of the fiber in a standard state) of 0.05%, and the bonding layer is formed of polyester yarn or polyamide yarn so that the process moisture content is higher than that of the back layer formed of polypolypropylene yarn. It is easy to transfer moisture from the water absorbing layer to the stitching layer.

In addition, polyester fiber or polyamide yarn of the bonding layer may use one fiber selected from the group consisting of false twisted yarn, A.T.Y and I.T.Y to increase the specific surface area and increase the water transfer rate.

Combustible yarn is a yarn that improves the volume and feel of yarn by artificially twisting untwisted yarn and then twisting it in the opposite direction. Typically, false twisted yarn has a 20 ~ 30% increase in specific surface area compared to unburned yarn.

In addition, ATY (Air Textured Yarn) yarns are produced to inject yarns into the entanglement structure by injecting air to the sides of the yarns for the purpose of improving the volume and feel like combustible yarns. Inter-lace Yarn yarns can also be made to increase the specific surface area of yarns. Like D.T.Y, A.T.Y and I.T.Y yarns have a 20 to 30% increase in specific surface area compared to normal yarns.

In addition, in order to increase the specific surface area of the polyester yarns or polyamide yarns, it is preferable to use the polyester yarns or polyamide yarns as shaped cross-sections of 3 to 6 germ layers as shown in FIG.

In general, the 3 to 6 germ-shaped sectioned yarn has a 20 to 80% increase in the cross-sectional area of the yarn compared to the circular section yarn, which increases the moving medium of the moisture and also increases the diffusion area of the absorbed moisture, thereby shortening the drying speed.

In addition, the polyester yarn or the polyamide yarn is formed of a microfiber to maximize the pore capillary phenomenon can increase the rate of water transition.

In general, a single yarn is composed of several strands of filaments, and as the number of filaments increases, more micropores of the fiber are formed, thereby improving absorbency due to the void capillary phenomenon. That is, the more filaments of the yarns constituting the Hanol yarn in the yarn of the same fineness, the better the water absorption.

Accordingly, when polyester yarns or polyamide yarns are formed with microfiber yarns, more filaments can use the filament yarns than general polyester yarns or polyamide yarns, thereby increasing the rate of water transition.

The self-regulating layer 100 and the water transition layer 200 may be prepared, respectively, to produce a heat-insulating fabric in which the thickness of the present invention is self-controlled by a lapping process. The combination process may be carried out by various methods such as sewing, adhesion, entanglement.
