Description

Method for making seamless pieced clothes

Technical field:

The invention relates to the technical field of garment processing, and in particular to a method for manufacturing a seamless split garment.

Background technique:

At present, most of the existing clothing methods use the traditional sewing machine sewing process, sewing the different parts of the front piece, the back piece, the sleeve, the collar, etc., and then sewing the whole piece. Partially stitched together to make a ready-to-wear. In this way, the sewing thread or the connection gap is inevitably exposed on the appearance of the clothes, so that in addition to affecting the appearance of the clothes, it is also easy to cause the partial sewing thread to be broken due to the cleaning of the honing or the scratching of the foreign objects. This may cause the clothes to go off the line and open, which seriously affects the wearing of the clothes. In addition, during the sewing process, the piercing of each needle in the sewing process will permanently damage the structure of the fabric, resulting in reduced tear resistance, and the clothes are worn on the body. It is easy to cause the joint interface to rupture; finally, the garment overlaps the splicing, up to 6 layers, very thick, not easy to flatten, and the fabric is easy to wrinkle, affecting the flatness and appearance of the product and the weight of the obtained garment is not light enough.

With the continuous improvement of people's material living standards, the requirements for the aesthetics and practicality of wearing clothes are getting higher and higher. In the case of manufacturing a waterproof garment using a waterproof fabric, in order to waterproof, the seam of the waterproof fabric is bonded by a tape at the joint portion of the waterproof fabric, and the tape is connected to the waterproof fabric by hot air heating. The operation method can realize the seamless connection of waterproof garments, but at present, this method is only used for the waterproof fabric, but it is not used for other fabrics, especially the cotton, wool, silk, nylon, chemical fiber and other fabrics commonly used in daily clothing. The main reason for the garment making situation is that the waterproof fabric already has a rubber sole, so it is easier to bond it with tape. The general cotton, wool, silk, nylon, chemical fiber and other fabrics do not have a rubberized surface, so it is not possible to simply press the joint directly with the tape. Since this problem has been and has not been overcome, it has not been seen in the market so far. A garment that is processed by pressing on a common fabric such as cotton, wool, silk, nylon, or chemical fiber.

Summary of the invention:

The object of the present invention is to provide a method for manufacturing a seamless split garment, which can directly press and bond the general cotton, wool, silk, nylon, chemical fiber and the like with a tape, and has a wide application range, and can be made according to different fabrics. In particular, the four-sided elastic knitted fabric is used to prepare clothes of any use and shape, and the obtained clothes have an accuracy of 0.1 mm, which is free from hot, conformal, beautiful, light, washable, machine washable and not deformed after washing.

The present invention is achieved by the following technical solutions:

A method for manufacturing a seamless piece of clothing, the method comprising the steps of:

(1) Cutting the fabric into a suitable shape and size with a laser;

(2) applying an adhesive within a width of 2-15 mm of the joint edges of the two pieces to be joined;

(3) The two pieces of the pieces are joined together relatively, and the cloth of the two pieces is bonded together by a flat heat press or a laser irradiation adhesive.

The binder is a combination of a hot melt adhesive and a silicone hydrogel selected from the group consisting of PU or TPU.

The hot melt adhesive and the silicone hydrogel have a mass ratio of from 1 to 10:1, preferably from 1 to 5:1, more preferably from 1 to 2:1.

In particular, the step (2) is to apply an adhesive tape having a release paper thickness of 0.08-0.1 mm to a width of 2-15 mm of the joined edges of the two pieces to be joined, respectively. The knot tape is adhered to a composition of the binder hot melt adhesive of the present invention and a silicone hydrogel selected from the group consisting of PU or TPU.

The two pieces of cloth are cloth of the same material or cloth of different materials.

In particular, the step (2) also uses a mold and a mat, and the two pieces to be joined are placed in the corresponding mold and the mat, and the obtained finished product is further included to better shape.

The cloth piece cloth is a cloth of cotton, wool, silk or chemical fiber.

The chemical fiber component includes polyester, nylon, spandex, acrylic, aramid, and polyamide.

The binder of the invention is synergistic effect of PU or TPU and silicone hydrogel, and the general cotton, wool, silk, nylon, chemical fiber and the like are simply pressed and joined by a tape directly, and the connection is firm, between the fabrics. Peeling strength is 15.9-16.6N/cm, washed by water at 40°C for more than 10 times, no delamination after 45 minutes, and the peeling strength after washing is greater than 7-13N/cm, far greater than the international standard 5.0N/cm. And can guarantee the accuracy of the obtained clothes is controlled at 0.1 mm, the flatness is good, the transition is natural, the ironing is free, the shape is preserved, the flexibility is good, the washing is resistant, the machine is washed, and the washing is not deformed.

Further, the advantages of small laser focusing point, concentrated heating, and convenient adjustment are utilized, and the cloth can be cut and joined more accurately. The precision of the clothes joined in this way is further ensured at 0.1 mm, and the connection is more tight, and the joint is tight. Better results.

The beneficial effects of the present invention are as follows:

1) By using the invention, the general cotton, wool, silk, nylon, chemical fiber and other different fabrics can be directly pressed and joined by a simple tape, the steps are simple, and the smooth joining of different kinds of fabrics is realized, and the connection is firm, and the fabric is The peeling strength between the two is 15.9-16.6N/cm, and the water is washed by water at 40 °C for 10 times or more. After 45 minutes, no delamination is observed, and the peeling strength after washing is greater than 7-13 N/cm, which is far greater than the international standard 5.0N. /cm, thus producing a different garment effect than the prior art, the garment obtained by the invention has an accuracy of 0.1 mm, good flatness, natural transition, no hot, no shape, good appearance, good flexibility, washable, machine washable and It does not deform after washing, and solves the general cotton, wool, silk, nylon, chemical fiber and other fabrics. It can not be directly pressed and bonded with tape to obtain precision of 0.1 mm, good flatness, no ironing, shape protection, washing resistance, Technical problems of machine washing and no deformation after washing.

2) The invention has wide application range, and can prepare clothes of any use and shape according to different fabrics, especially four-sided elastic knitted fabrics, and can replace the existing sewing garment technology to manufacture clothes of any existing variety of fabrics. Overcoming the shortcomings of the existing non-sewing thread garment technology can only be applied to the waterproof fabric manufacturing waterproof garment.

3) The invention can make the garment automatically completed by the device, and basically does not require manual intervention, so it is beneficial to realize automatic production, save a lot of manpower and material resources, can effectively reduce the cost of garment manufacturing, and improve economic benefits.
