Description

Detailed Description of the Invention (Industrial Field of Application) This invention relates to a double-layer fabric with threads inserted between a bound face fabric and a 7A m material to have a three-layer structure. It is used as a filling material for clothing, especially for sportswear and cold-weather clothing, as well as for insulation materials, bags, etc.

(Prior art and its problems) Cold-weather sportswear and other cold-weather clothing use batting materials in which feathers or synthetic cotton are sandwiched between the outer material and the lining, and quilted in arbitrary patterns. However, the above-mentioned quilted padded material is expensive because it requires multiple processes such as weaving of the outer material, weaving of the lining, and quilting. There were problems such as the batting breaking, making it difficult to wash, and lacking in easy care.

On the other hand, as clothing materials with a three-layer structure that does not rely on quilting, there are two-layered fabrics with threads in which warp or weft threads are sandwiched between a sticky outer fabric and a backing fabric, as well as outer fabrics that are tied together. , a bonded triple weave consisting of an intermediate fabric and a lining fabric are known, but these conventional fabrics with a layered structure do not require increasing the thickness of the fabric or creating a fabric with a unique color on the front and back sides. Because the purpose is to use regular yarn in each layer and to arrange the joints in a scattered manner so that the joining points are not noticeable, the appearance is smoother and has an uneven pattern compared to conventional quilted padded materials. It had a hard texture and poor cooling properties.

In addition, in the weft triple-weave fabrics, fabrics using temporary twisted threads or pressed threads for the intermediate weft threads are
This is known from Japanese Patent No. 8145, and since it is woven with double warp yarns and triple weft yarns, it has a smoother appearance compared to quilted, padded material, similar to the above-mentioned conventional layered fabric. and does not have an uneven pattern,
The texture was hard. Even though twisted yarn is used for the middle layer, because it is a triple-weave weave as mentioned above, it is not possible to use a large amount of twisted yarn to form the shape of padded cotton. However, it was not possible to obtain the flexibility and heat retention of quilted, padded materials.

(Means for Solving the Problems) The present invention provides a double-layered fabric with threads in which threads 3 are arranged between two fabrics 1.2 on the front and back sides of a bonded double weave, in which the threads 3 are It is a bulky yarn, and the joining points 4a of the front and back fabrics 1.2 are arranged in the form of one quilting stitch to form a joint pattern line 4, and at least the front fabric 1 of the front and back fabrics 1 and 2 is This is a double-woven fabric with threads, which is characterized by bulging out between the binding pattern lines 4 to form a concavo-convex pattern.

The warp yarns 1a and the weft yarns 1b constituting the front fabric 1 are cotton yarns, wool yarns, and blended yarns 1 of cotton fibers and synthetic fibers stable.
Synthetic filament yarns and their additions, etc.
It is similar to that used for the outer material of conventional quilted, padded materials, and is woven to the same texture and density as the conventional outer material.

However, the heat treatment after weaving causes the thread 3 to curl and bulge between the bound pattern lines to form an uneven pattern, so the heat shrinkage during this heat treatment is smaller than that of the thread 3. It is necessary.

Warp yarn 2.1 and weft yarn 2b+ of fabric 2) are similar to those used for the lining of conventional batted materials, and in particular, woolen yarn, 2C and other raised yarns are used to improve the heat retention effect. Can be mixed and raised.

Although FIG. 2 shows the woolen yarn 2C arranged in the weft direction, it may also be arranged in the ta-c direction.

The thread 3 is substantially untwisted, such as synthetic fiber twisted thread, pressed processed thread, or composite fiber thread, and exhibits great bulk properties through crimping treatment, and its preferred thickness is as follows: 50-600 denier, preferred density is 10-600 denier
50 lines/cm. If the thickness of the threads 3 is less than 50 denier or the density is less than 0 threads/salt, the effect of the cotton padding cannot be obtained, and on the other hand, if the thickness of the threads 3 exceeds 600 denier, If the density exceeds 50 threads/cm, weaving becomes difficult. Note that the thread 3 may be oriented either in the two directions shown in the figure or in the warp direction, but in the case of the warp direction, a separate loom beam is required. , The above-mentioned 9 front fabric l and the lining fabric 2 have the weft 2 of the lining fabric 2.
connected by b. Note that the warp threads 2a or both may be used for binding. In a normal double-woven weave, the joint points 4a are arranged in scattered dots like satin dots so that they are not noticeable. However, in the present invention, the joint points 4a are arranged in the warp direction and in the horizontal direction like the seam line of quilting. The connecting pattern lines 4 are formed by arranging them in a straight line, a curved line, or a grid pattern. In the drawing,
This figure shows that the vertical joint-like lines 4 are provided at two different intervals, wide and narrow.

(Function) A bulky thread is used as the thread 3 of the double-layered fabric containing thread, and the joining point 4a of the front fabric 1 and the back fabric 2 is a quilting pattern. As a result, the above-mentioned shin threads 3 sufficiently exhibit bulkiness between the above-mentioned front fabric I and back fabric 2.

Therefore, it exhibits the same heat retention properties as conventional padded cotton, and has the same appearance as conventional quilted fabric.

Since the double connecting points 11, 1 fix the bulky threads 3 to the front fabric 1 and the lining fabric 2 at predetermined intervals, the bulky threads 3 may move or The threads will not split or break.

(Example) Cotton yarn (60 count double yarn) was used for the warp yarn 1a and the weft yarn tb of the front fabric 1, and the density of the warp yarn 1a was set to 43 threads/cm, and the density of the weft thread tb was set to 34 threads/cIn.

In addition, cotton threads (
60 count double yarn) is used, and the weft yarn 2b is a woolen yarn (16
Metric count) 2c was mixed at a ratio of 1/1, and the density of the warp yarn 2a was set to 11 yarns/cm, and the total density of the weft yarn 2b and woolen yarn 2c was set to 11 yarns/cm. In addition, the thread 3 is a temporarily twisted polyester fiber thread 150 denier 3.
A zero filament twin yarn was used, and the density was set to 15 threads/cII+ as the weft thread. A two-piece multicolor loom is used, and the front weave is plain weave and the back weave is 3/1 twill.

The connection points 4a are arranged in a straight line in the vertical direction as shown in the drawing, and 2
Ii! so that the distance between the binding pattern lines 4 of the book is 3m and L6nwn! After weaving, the resulting double woven fabric with twine is subjected to a lilac treatment under boiling conditions for 30 minutes to cause crimp in the twine 3, and the width of the fabric is reduced by approximately 21%.
The outer fabric 1 and the 1 Jtm fabric 2 were shrunk to bulge out like quilting fabric, and were then set in a napping machine to raise the woolen yarn 2c of the lining fabric 2. The obtained product is a double woven fabric with twine, but has the appearance and soft texture of a quilted product, has excellent heat retention, and is a cowhide garment with a raised lining fabric 2. The texture was also good.

7 (Effects) ゛It has the same appearance and texture as the conventional quilted padded material, and since it is a double-woven fabric with regular threads, the manufacturing process is shorter than the conventional padded material mentioned above, and there is no need for brackets. There is no hole like a sewing machine's needle hole in the knot, and since the filling is made of bulky yarn, there is no chance of the filling being cut, and it can be washed.
