Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fabric having improved air permeability, warmth and stretchability,

The present invention relates to a fabric having improved breathability, warmth and stretchability, and a method of manufacturing the same. More specifically, the present invention relates to a fabric having three or more yarns different in elasticity, alkali resistance and heat resistance, By forming the embossed space in the circular section by the finishing process, it is possible to improve the warmth and air permeability by the ventilation hole in the hollow layer and to improve the elasticity according to the material and processing of the yarn to improve the breathability, warmth and stretchability And a manufacturing method thereof.

Generally, clothes are convenient for all people to wear, especially when exercising with a lot of body movements, they want to wear sweaty clothes that do not feel cold because they have good heat after exercise.

In recent years, a functional fabric having various functions such as ventilation, waterproof, windproof, antibacterial and the like has been a mainstream for the above-mentioned sportswear, and efforts to develop such fabrics have been actively conducted.

Recently, sweat and heat generated during exercise have become popular. However, when the amount of perspiration to sweat is small, it is possible to sweat the sweat quickly to the outside of the cloth When the amount of sweat on the cloth is large, the function is not sufficiently exhibited, and the clothes stick to the body, causing inconvenience due to the movement, and causing discomfort due to stickiness. Especially when taking a rest after a lot of sweat such as climbing, There is a problem that the user feels cold.

In recent years, Korean Patent Registration No. 10-0959509 discloses a fabric developed as a method of manufacturing a highly breathable fabric. This is because when the fabric is inserted into the fabric at a predetermined interval, the fabric is melted in the refining process, The ventilation is very good because it has a lattice-shaped air hole. However, when the cloth is not used as a stretchable material, it is inevitable that the wearer wears a sportswear such as a knee, an elbow or a hip, If you take a rest in the mountains, there is a problem that the body does not warm up and you feel cold.

Korean Patent Registration No. 10-1421222 discloses a fabric having a multi-layered structure having breathability and elasticity. However, the fabric is made of coarse yarn and woven in double or triple stitches, Is used for clothes such as bed mattresses, sofas, chairs, etc., which are not used for clothing, and which have good breathability and elasticity, and are used for bedding such as mat pillows and the like such as general sportswear. What I want to do is not only different from the technical field of the invention, but also lacks elasticity.

In addition, Korean Patent Publication No. 10-1251242 (breathable and waterproof fabric), No. 10-1520790 (functional polypropylene fabric and its production method), No. 10-0659567 (polyester fiber and woven and knitted fabric using the same) But they are all satisfactory in one field, but have problems that can not simultaneously satisfy air-tightness, breathability, warmth and stretchability.

Accordingly, it is an object of the present invention to develop a cloth having improved breathability, warmth, comfort, and stretchability, which can simultaneously solve the above-described problems, and a method for producing the same.

Korean Patent Publication No. 10-0959509 Korean Patent Publication No. 10-1421222 Korean Registered Patent No. 10-1251242 Korean Patent Publication No. 10-1520790 Korean Patent Publication No. 10-0659567

The present invention has been developed in order to solve the above-mentioned problems simultaneously, and it is an object of the present invention to provide a polypropylene yarn (hereinafter referred to as "PP yarn") and a partially stretched yarn Quot;) and rubber yarn to improve the breathability, warmth, comfort and stretchability of the fabric.

Further, the present invention provides a method for manufacturing a fabric fabric for improving warmth by forming an embossed embossed layer on a fabric by various processing steps so as not to feel a chill when taking a rest during climbing with a lot of sweat .

In order to solve the above problems, the present invention relates to a method for producing an intermingled yarn by mixing PP yarn, Poy yarn and rubber yarn with air interlaced yarn, ) And the poy yarn is shrunk and melted by the refining operation at the same time, thereby forming embossed pores in the fabric surface, thereby providing a fabric having improved breathability, warmth and stretchability.

At this time, the PP yarn preferably has a thickness of 30 to 100 denier, and single yarn can be used, but using multifilament yarn is more effective for warmth.

In addition, since Poy is used for high-speed casting, it is more effective to use monofilament yarn of 40 to 60 denier.

The rubber yarn preferably has a rubber yarn count of 35 to 60 in terms of the inverse number of the yarn in inches, and is intended for high elasticity of the fabric by spandex yarn.

A method of manufacturing a fabric having improved air permeability, warmth and stretchability,

A step of producing an intermingling yarn for knotting a PP yarn, a Poy yarn and a rubber yarn by air interlacing in an interlacer; a step for producing a fabric of a blocking or double knit by hanging the intermingling yarn on a circular knitting machine; A first step of fixing the PP yarn to a bulky form by strong shrinking force of the Poy yarn by setting the yarn on a rapid steamer at 85 to 110 ° C, NaOH) solution to melt the Poy yarn, and the step of washing and dehydrating and drying the fabric in which the Poy yarn is melted and removed.

In the above, the PP yarn has a thickness of 30 to 100 denier, and although single yarn can be used, the use of multifilament yarn is more effective for keeping warmth because it has good shelf life.

In addition, Poy is used for high-speed casting and is used for melting and removing, so it is more effective to use monofilament yarn of 40 to 60 denier.

The rubber yarn preferably has a rubber yarn count of 35 to 60 in terms of the number of inches of the yarn, and when the yarn count is less than 30, the rubber yarn is too thick to thicken the fabric. When the yarn count exceeds 60 Care should be taken as there is a risk that the rubber yarn will be weakened and cut, and the rubber yarn is for the high stretchability of the fabric.

In addition, in the above, since the place where the Poy yarn melts remains as a space, a pronounced emboss is formed, so that it can contain a lot of air, thereby preventing the heat from escaping from the body and preventing the outside cold air from penetrating into the clothes Therefore, the heat insulation effect becomes excellent.

The fabrics having improved breathability, warmth and stretchability according to the present invention can be manufactured by manufacturing clothes for sportswear or outdoor wear, which is good in ventilation in a well ventilated environment and cool in an environment where winter convection is blocked. Therefore, it is effective to provide clothing fabric that can be worn at any time because of its high warmth.

In addition, in the case of sweaty exercise, mountain climbing, etc., the air layer of the concave-shaped emboss has an excellent effect of causing capillary phenomenon and discharging sweat out of the body.

In addition, the present invention is effective in use as a sportswear having a high activity because it has a stretchability in four directions by combining a stretchable rubber yarn and a stretchability of a fabric, which is a characteristic of a knitted fabric by a circular knitting machine.

Further, since the PP is a main material of the fabric, the present invention can be used in a field of functionality because PP has a strong strength, a long life span, and good sweat discharge.

In the present invention, intermingled yarn is produced by intermingling PP yarn, Poy yarn and rubber yarn with air entanglement, and then the intermingled yarn is knitted with the intermingled yarn in a circular knitting machine, steamer) and at the same time refining operation, the poy yarn is shrunk and melted to form embossed pores in the fabric surface, thereby providing a fabric having improved breathability, warmth and stretchability.

In the above, weaving with a knitting machine using a circular knitting machine or a double knit knitting machine is for imparting smooth stretchability in four directions of up, down, left and right of the fabric.

The PP yarn is a main material of the fabric of the present invention and preferably has a thickness of 30 to 100 deniers. However, the thickness of the PP yarn is not particularly limited, and may be selected according to need, and monofilament or multifilament However, when a single yarn is used, the strength of the fabric is strong and the service life can be prolonged. In the case of using the multifilament yarn, the warmth is further improved.

In addition, since Poy is used for high-speed casting, it is preferable to use monofilament yarn of 40 to 60 denier. In particular, when the refining is performed by dissolving with sodium hydroxide, the portion occupied by Poy in the fabric becomes empty, Shaped boreholes are formed to effectively improve the breathability and warmth.

The rubber yarn preferably has a rubber yarn count of 35 to 60 in terms of the inverse number of the yarn in inches, and is intended for high elasticity of the fabric by spandex yarn.

On the other hand, in a method of manufacturing a fabric having improved air permeability, warmth, and stretchability,

A step of producing an intermingling yarn by supplying PP yarn, Poy yarn and rubber yarn to intermingle yarn by intermingling with air entanglement to obtain knotting effect, and a step of intermingling the intermingling yarn with a circular knitting machine to produce a fabric of a jersey or double knit A step of setting the fabric at a rapid steamer at 85 to 110 ° C to fix the PP yarn so that the PP yarn becomes a bulky shape due to the strong contraction force of the Poy yarn, Characterized in that the step of refining in a sodium hydroxide (NaOH) solution at a weight% to melt the Poy yarn and the step of cleaning and dehydrating and drying the fabric in which the Poy yarn has been melted and removed.

In the above, the supplied PP yarn is the main material constituting the fabric and has a low shrinkage rate due to heat. Poy yarn is a catalyst material constituting the fabric and has a large shrinkage rate due to heat. Rubber yarn is made of spandex yarn with good stretchability, In the process, PP yarn and Poy yarn: rubber yarn are fed at a ratio of 2.5: 1 to 3.5: 1 strands to produce a yarn yarn with knot effect at regular intervals.

If PP and Poy are less than 2.5 times of the rubber, the thermal stability and air permeability are lowered because of low vulcanization. If the PP and Poy are more than 3.5 times, it is difficult to form a reliable knot in the intermingling process.

In addition, knitting the intermingling yarn into a knitted fabric by using a knitting machine with a knitting machine or a double knit fabric is for imparting smooth stretchability in four directions of up, down, left and right of the fabric. Due to the nature of the mingle yarn, it is effective to use the circular knitting machine because of the difficulty in the penetration and intrusion.

In addition, the PP yarn preferably has a thickness of 30 to 100 denier, and although single yarn can be used, it is better to use multifilament yarn because it is more comfortable for warmth.

It is more effective to use 40 to 60 denier monofilament yarn because the Poy yarn is used for high-speed casting and it is to be melted and removed. Because of the difference in heat shrinkage ratio between the PP yarn and the PP yarn before the Poy yarn is melted, It is possible to provide a fabric having an air layer that can contain a large amount of air by forming more space due to the setting as the phenomenon occurs.

In the refining operation, if a sodium hydroxide (NaOH) solution of 25 to 35% by weight is immersed at 80 to 100 ° C. for 20 to 30 minutes and then washed and dehydrated, all the impurities and the phosphorus are melted and removed. Not effective.

If the content of sodium hydroxide is less than 25% by weight, the melting of the Poy can not be completed, and if it exceeds 35% by weight, the rubber yarn and PP yarn may be damaged.

The rubber yarn preferably has a rubber yarn count of 35 to 60 in terms of the number of inches of the yarn, and when the yarn count is less than 30, the rubber yarn is too thick to thicken the fabric. When the yarn count exceeds 60 Care should be taken as there is a risk that the rubber yarn will be weakened and cut, and the rubber yarn is for the high stretchability of the fabric.

In addition, in the above, since the place where the Poy yarn melts remains as a space, a pronounced emboss is formed, so that it can contain a lot of air, thereby preventing the heat from escaping from the body, and preventing the outside cold air from penetrating into the clothes So that the thermal effect is excellent.

Unlike conventional breathable fabrics, PP yarn, Poy yarn and rubber yarn are supplied to produce intermingle yarns having knots at regular intervals in an intermingling process, and the intermingle yarns are wound on a circular knitting machine The present invention provides a fabrics having enhanced air permeability, warmth and stretchability by melting and removing Poy yarn in a refining process after the fabrication process, and a fabricating method thereof, and various substitutions, modifications, and alterations can be made without departing from the technical idea of the present invention. It will be apparent to those skilled in the art that the present invention can be carried out without departing from the scope of the present invention.
