Description

Three-dimensional knitted fabric and its sewing method

The invention relates to a three-dimensional knitted fabric sewing method, in particular to a three-dimensional knitted fabric sewing method, and a garment structure prepared by the sewing method.

Existing fabric sewing methods, such as the production of women's bra cups, generally use needle-punched fabric or foam; however, foam products are stuffy, airtight, and easy to change color, and there are also concerns about pollution in the manufacturing process. The needled fiber fabric will cause fiber loss after washing, which will deform the finished product and shorten the service life.

The three-dimensional knitted fabric is a three-layer fabric, which includes a supporting yarn sandwiched between two veils, which can hold up the two veils, so the hardness is relatively high. However, the splicing and sewing methods of the prior art are prone to leakage of the supporting yarn, which severely irritates the skin, thereby reducing the comfort. In view of this, the current sewing method is not preferred when using three-dimensional knitted fabrics to sew fabrics. For example, most of the bra cups are molded by compression molding, but the compression molding method wastes a lot of materials, resulting in a substantial increase in cost, and It is impossible to completely avoid the shortcomings of supporting yarn leakage. According to this, the three-dimensional knitted fabric cannot be effectively popularized.

For these reasons, this three-dimensional knitted fabric and its sewing method are specially developed to save waste of resources, reduce costs, and improve the comfort of the application of clothing, mattresses and other products made of the three-dimensional knitted fabric.

The technical problem to be solved by the present invention is to provide a three-dimensional knitted fabric sewing method and a three-dimensional knitted fabric structure in view of the deficiencies of the prior art.

In order to solve the above-mentioned technical problems, one of the technical solutions adopted by the present invention is to provide a sewing method of three-dimensional knitted fabric, which includes: providing a first three-dimensional knitted fabric and a second three-dimensional knitted fabric, the first three-dimensional knitted fabric The knitted fabric has a first inner edge, and the second three-dimensional knitted fabric has a second inner edge; placing a first fluffy flexible wire between the first inner edge and the second inner edge; and stitching The first inner edge and the second inner edge form a seam structure that wraps the first fluffy flexible wire; wherein the diameter of the first fluffy flexible wire is larger than that of the first three-dimensional knitted fabric and The thickness of the second three-dimensional knitted fabric is more than 0.2 cm.

One of the beneficial effects of the present invention is that, provided by the present invention, it can pass "the first three-dimensional knitted fabric with a bulky flexible wire" and "the diameter of the first bulky flexible wire is larger than that of the first three-dimensional knitted fabric and The technical solution that the thickness of the second three-dimensional knitted fabric is more than 0.2cm" can overcome the shortcomings of supporting yarn leakage, and solve the problem of uneven protrusions at the seam after the fabric is sewn, and can maintain the product after sewing. Skin-friendly comfort. In addition, the present invention can effectively omit the additional use of surface cloth strips at the seam or edge, avoid the increase in thickness, and can also avoid wearing marks when applied to the sewing of clothes.
