Weaving METHOD OF TWO-LAYER FABRICS WITH HEAT INSUALATION/ALL DIRECTIONS ELASTICITY}

The present invention relates to a method of weaving a double fabric having light insulation and stretchability in all directions, that is, stretchability in a warp direction and a weft direction.

In general, as a means for increasing the heat retention in the fabric, there is a means for weaving the fabric by double weaving to form an air layer, and also, in the case of sports clothes or outdoor clothes, a lot of activity is required, so fabrics with excellent elasticity are preferred.

As a means to increase the heat retention, when examining the prior art related to the fabric that is woven by double weaving to form an air layer, Patent Publication No. 10-2017-0100955, "Seamless tubular fabric fabric and its use" (Patent Literature 1) and Patent No. 10-1914280, "Tri-woven woven thermal insulation paper and padding paper and padding products using the same" (Patent Document 2).

Looking at the technical content of Patent Document 1, the seamless fabric of the tubular fabric for sewing is a base fabric facing two layers of fabric woven into multiple tissues by a jacquard loom, and the base fabric is filled with a predetermined pattern according to the pattern of multiple tissues. A structure consisting of a plurality of stitching sections divided into spaces and a predetermined filling section section divided by the stitching section on the base fabric. In the fabric weaving step, two layers of fabric are joined together without a sewing agent by a pattern of multi-tissues. Since it is processed without needle sweat of a dense tissue and a seam, it is possible to fundamentally prevent detachment of a filler filled in a filling space, and provides functionality such as waterproofing, windproofing, insect repellent, rainproofing on one or both sides of the non-seamless tubular fabric. Since it is possible to laminate the film layer or to further layer the surface layer of the fabric or knitted fabric, it is particularly useful for down-proof winter clothing and tick-proof bedding using the same.

In addition, when examining the technical contents of Patent Document 2, it is a triwoven fabric fabric formed by weaving and having three layers of upper and middle layers and lower layers. The upper connecting line formed linearly between these layers between the upper and middle layers. When they are spaced apart and formed repeatedly two or more, upper filling spaces are formed between the upper connection lines, and lower connection lines formed linearly between these layers between the middle and lower layers are spaced apart and formed repeatedly two or more times, and the lower connection line It is characterized in that the lower filling spaces are formed between them, no contact is made between the upper layer and the lower layer, and the upper connecting lines and the lower connecting line are arranged so as not to overlap each other up and down.

In the case of Patent Documents 1 and 2, there is also an advantage of providing a fabric having excellent heat retention by forming a space through a contact portion and a spaced apart portion, that is, an air layer, in the weaving process.

However, in the case of the above fabric, it may be said that the warmth can be secured, but there was some inconvenience in sports clothes or outdoor clothes that do many activities due to lack of elasticity.

Patent Publication No. 10-2017-0100955 "Seamless tube-type fabric fabric and its use" Patent No. 10-1914280 "Tri-triple insulating paper and padding and padding products using the same"

The present invention relates to a method of weaving a double fabric suitable for the manufacture of sports clothing or outdoor clothing, and is particularly lightweight and excellent in heat retention, and imparting elasticity in all directions, i.e., in the inclined direction and the weft direction, thereby providing excellent fit and activity. It is to provide high quality double fabric.

As a means for solving the above problems, the present invention arranges a slope with a stretchable yarn, and repeatedly arranges a contact slope and a spacer slope, and then consists of a surface weft made of a non-stretchable plain yarn and a stretchable yarn. By interposing the back weft yarns alternately, the surface weft and the back weft are interlocked to form a single-ply weave in the joint slope, and in the inclination of the space, the surface weft is interwoven with the space slope to form the surface fabric, The weft yarns are not organized with the inclined spacers, and an amorphous part that remains only the back weft is formed, so that a spaced part is formed between the surface fabric and the amorphous part, and the amorphous part is reduced in width by the elasticity of the back weft through the spaced part. Therefore, the surface fabric is bent in a curved shape, so that an air layer is formed.

The present invention arranges the slope with a stretchable yarn, repeatedly arranges the joint slope and the spacer slope, and then alternately inserts the surface weft made of the non-stretchable plain yarn and the back weft yarn made of the stretchable yarn alternately. On the slope, the surface weft and the back weft constitute an interwoven fabric, that is, the abutment, and on the slope of the space, the surface weft is interwoven with the spacer slope to form a surface fabric, and the back weft is not organized with the spacer slope. By forming an amorphous structure in which only the weft yarns remain, a separation portion is formed between the surface fabric and the amorphous portion, and through the separation portion, the amorphous portion is reduced in width due to the elasticity of the back weft, and thus the surface fabric is bent in a curved shape. By forming the air layer, it is light and excellent in heat retention, and gives elasticity in all directions, that is, in the inclined direction and the weft direction, thereby obtaining a high quality double fabric with excellent fit and activity, and using the double fabric as a material for sports clothing or out. It has the effect of being usefully applied to door clothing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The double fabric to be provided in the present invention is light and excellent in heat retention, and in particular, high-quality clothing excellent in wearability, heat retention and activity when applied to sports clothing or outdoor clothing by adding elasticity in all directions, that is, in the inclined and weft directions. It is intended to provide products.

The schematic basic configuration is to use all of the warp (WP) used when weaving a double fabric (10) using a loom as a stretchable yarn, but the warp (WP) is again connected to the joint slope (WP1) and the spacer slope (WP2). To distinguish.

In the case of weft, the surface weft applied to the surface fabric (40) and the back weft forming the amorphous part (60) of the back side are divided into surface weft. , Backing fabric, that is, the back weft constituting the amorphous portion 60 uses the same stretch yarn as the warp (WP).

The stretchable yarn used in the above includes all stretchable fiber yarns such as stretch yarns, covering yarns, and spandex yarns.

The weaving form of the double-woven fabric 10 using a loom is a contact portion 20 and a spaced portion that is woven in a form of a single layer by weaving alternately the surface weft and the back weft in the contact portion slope WP1 opened by the heald. The surface fabric 40 and the amorphous portion 60 through the surface fabric 40 in which the warp (WP2) and the surface weft are organized, and the non-organized portion 60 that is not organized in the spaced portion inclination (WP2) and only the back weft remains. ) Between the isolation portion 30 is formed.

Therefore, when the functional double fabric 10 is woven, elasticity is imparted in the warp direction and the weft direction using the stretched yarn. In particular, in the separation portion 30, the back weft using the stretchable yarn, that is, the stitching section 20 and the stitching section ( 20) Since the width is reduced in the amorphous portion 60 connecting the surface fabric 40 separated through the relatively amorphous portion 60 and the separation portion 30, the air layer is bent as the width of the back weft is reduced. To form.

In constructing the double fabric of the present invention, the reason for using the stretchable yarn for the warp WP is to maintain the shape stability of the double fabric by properly maintaining the weft density of the double fabric while imparting elasticity in the oblique direction. .

In addition, the non-woven portion 60 composed of only the back weft on the back side of the double fabric 10 provides sufficient elasticity in the weft direction, and makes the warp that does not become textured with the back weft to intersect with the surface fabric, thereby providing the It increases the inclination density and functions to increase shape stability and durability.

For another purpose, when the weft yarn is not composed of the amorphous part 60 and is interwoven with the warp yarn, the stretch range of the weft yarn made of a stretchable yarn is reduced as much as the density of the warp yarn, and the back side of the amorphous part 60 Since the soft touch feeling of the weft falls, it is preferable to form the amorphous part 60 for stretch and touch improvement.

An embodiment of the weaving process of the double fabric 10 to be provided in the present invention will be described.

The warp (WP), which is divided into the joint slope (WP1) and the spaced slope (WP2), uses stretched polyester 75D yarn, and among the weft (WT), the surface weft uses stretched polyester 150D yarn, The back side weft was made of a stretched polyester 75D yarn, the same as the warp (WP).

The thickness of the warp and weft yarns used above need not be limited, and yarns of various thicknesses can be used depending on the purpose and purpose of use of the functional double fabric, and the types of yarns can also be variously applied, such as natural fibers or synthetic fibers. .

In the above, while the warp and the back weft use a stretchable yarn, a part of the backside weft is made up of an amorphous part 60, and the surface weft is given a stretch in both directions, by using a yarn without stretch. As the surface fabric 40 is bent in a curved shape, an air layer is formed through the spacer 30 to maintain heat retention.

Figure 1 shows the one-circulation organization diagram (A) of the double fabric 10 of the present invention, the slope (WP) is divided into the joint slope (WP1) and the spacer slope (WP2), the joint slope (WP1) ) Is a four-strand consisting of a first slope (1WP), a second slope (2WP), a third slope (3WP), and a fourth slope (4WP), and the separation slope (WP2) is a fifth slope (5WP), The sixth inclination (6WP), the seventh inclination (7WP), and the eighth inclination (8WP) are repeated 5 times and are composed of 20 strands.

At this time, the number of strands of the joint slope (WP1) or the number of strands of the spaced slope (WP2) can be increased or decreased. If the number of strands of the joint slope (WP1) is increased, the width of the joint 20 increases and the weft direction increases. As the elasticity decreases, and the number of strands of the spacer slope WP2 is increased, the width of the spacer 30, that is, the amorphous part 60 increases, so that the stretchability and the air layer become large.

However, as the number of strands of the spacer slope WP2 increases, the elasticity and the air layer increase, but the shape stability and durability of the fabric may deteriorate, so it is appropriate to adjust and use it according to the purpose and purpose of use of the double fabric 10. desirable.

1 The width of the double fabric 10 for weaving the number of inclined strands in the circulating organizational chart (A), that is, repeatedly arranged as many as the total number of inclined strands, installed in the loom, made open by heald, and then weaving the weft to weave the fabric Is done.

Wefts that are inserted between the open slopes are alternately repetitively interposed between the stretchable back weft and the unstretchable surface weft.

It will be described based on the one circulatory organization diagram (A) of FIG.

That is, if the inclined WP is opened for the incidence of the 1st weft (1WT) on the back side, as shown in FIG. 2, the two strands of the 1st inclination (1WP) and the 3rd inclination (3WP) of the joint inclination (WP1), and all separations The slope of the sub-inclination (WP2), that is, the 5th slope (5WP), 5 strands, the 6th slope (6WP), the 5 strands, the 7th slope (7WP), the 5 strands, the 8th slope (8WP), 5 strands, the total of 20 strands Ascending, only the second inclination (2WP) and the fourth inclination (4WP) of the joint inclination (WP1) are opened in a descending state, and the flexible back weft (1WT) is placed in the opened state as above. do.

Therefore, the back side No. 1 weft (1WT) is a teaching material only at the joint inclination (WP1) to form the joint 20, and in the spacer inclination (WP2), all the slopes and tissues become non-organic and the surface fabric ( 40) to form an amorphous portion (60) spaced apart.

When the inclined WP is opened for the incidence of the surface 1st weft (1WT'), as shown in FIG. 3, the 1st slope (1WP), the 3rd slope (3WP), and the spacer slope ( WP2) 5th grade (5WP), 5th grade, 7th grade (7WP) 5th strand rises, 2nd slope (2WP), 4th slope (4WP) and spaced slope of the joint slope (WP1) (WP2) The 6th inclination (6WP) 5 strands, and the 8th inclination (8WP) are opened in a descending state, and in the opened state as above, the inflexible surface No. 1 weft (1WT') is inserted. .

Therefore, the surface number 1 weft (1WT') is made of the contact portion inclination (WP1), the separation portion inclination (WP2) and the tissue, and the contact portion 20 and the surface fabric 40 are woven.

When the inclined WP is opened for the insertion of the rear 2nd weft (2WT), the 2nd inclined (2WP) and the 4th inclined (4WP) of the joint inclined (WP1) and all the inclined inclined (WP2) as shown in FIG. ), that is, 5 strands of 5th slope (5WP), 5 strands of 6th slope (6WP), 5 strands of 7th slope (7WP), 5 strands of 8th slope (8WP), a total of 20 strands are inclined, and Only the first inclination (1WP) and the third inclination (3WP) of the conjunctive inclination (WP1) are opened in a descending state, and the elastic back weft (2WT) is retracted in the opened state as described above.

Therefore, the second weft (2WT) becomes a teaching material only at the joint inclination (WP1) and constitutes the joint 20, and in the spaced inclination (WP2), the surface fabric ( 40) and maintains the disorganized portion 60 spaced apart.

When the inclined WP is opened for the incidence of the surface 2 weft (2WT'), the 2nd inclination (2WP), the 4th inclination (4WP), and the spaced inclination ( WP2) 6th (6WP) 5 strands, 8th (8WP) 5th strands rise, 1st slope (1WP), 3rd slope (3WP) and spacer slope of the joint slope (WP1) (WP2) 5th inclination (5WP) 5 strands, 7th inclination (7WP) is opened in a descending state, and in the opened state as above, the inflexible surface No. 2 weft (2WT') is inserted. .

Therefore, the surface second weft (2WT') is made of a contact portion slope (WP1), a spacer slope (WP2) and a tissue, and the contact portion 20 and the surface fabric 40 are woven.

As shown in Figures 2 to 5, while opening the inclined WP sequentially, the elastic back 1st weft (1WT), the unstretched surface 1st weft (1WT'), and the elastic back 2nd weft (2WT) ), and by repeating the weaving means for overlaying the inelastic surface No. 2 weft (2WT'), the double fabric 10 to be provided in the present invention is weaved.

Therefore, in the case of the woven double fabric 10 as described above, as shown in FIGS. 7 and 8, the connecting portion slope (WP1) constituting the double fabric 10, that is, the first slope (1WP) to the fourth slope ( In 4WP), the backing weft (1WT), the backing weft (1WT'), the backing wefting (2WT), and the backing wefting (2WT') are interwoven with a single layer of fabric and the joints (20) Becomes weaving, and the first weft (1WT) and the second weft (2WT) in the fifth slope (5WP) to the eightth slope (8WP) section of the separation slope (WP2) are the separation slopes (WP2) And the non-woven fabric, an elastic portion 60 is formed between the contact portion 20 and the contact portion 20, and only the elastic back and second weft (1WT) (2WT) remain, and the surface first weft ( 1WT') and the surface 2 weft (2WT') are interwoven with the 5th slope (5WP) to the 8th slope (8WP) to form the surface fabric 40.

Therefore, since the width of the back 1st and 2nd weft (1WT) (2WT) located in the non-woven and non-woven portion 60 is reduced by the elasticity, the surface fabric 40 woven from a general weft without elasticity is elastic. As the length of the back weft is reduced, the air layer is formed by the separating part 30 between the back 1st and 2nd wefts (1WT) (2WT) and the surface fabric 40 made of the amorphous part 60 while bending in a curved form. Is formed.

In addition, since all the warps WP used for weaving the double fabric 10 are made of a stretchable yarn, stretchability is also provided in the warp direction in the state in which weaving is completed.

In particular, in the case of the double fabric 10 to be provided in the invention, since all the warp yarns (WP) and all the back weft yarns are made of an elastic yarn, bi-directional warp yarns are given, that is, four-sided elasticity, and the back weft yarns using an elastic yarn It does not become inclined and interwoven, and as the width decreases in an amorphous state, bulkiness is maintained, so that the touch feeling on the back surface portion of the double fabric 10 is maintained smoothly, and the air layer located in the separation portion 30 maintains heat retention. To maintain.

Therefore, when used as a material for sports clothing or outdoor clothing by using the double fabric 10, it is possible to provide high-quality clothing having excellent activity, lightness, and excellent touch and heat retention.
