What is a seam? How is its craft?

With the development of science and technology and the improvement of people's living standards, the production mode and application scope of quilted products have changed greatly.

Quilted products used to mainly refer to ordinary bedding such as quilts and mattresses, but now they have been extended to Simmons, sofa fabrics, handbags, bags, shoes and hats, clothing and other products, from practical products to craft gifts, from home to clothing.

Quilting enhances the practicality and aesthetics of quilted products with its rich changes, and creates a comfortable and warm living space for people.

Primary quilting technology of 1. 1

What is first quilting? According to the explanation given in Ci Hai, quilting means sewing a textile fabric with a long needle and fixing cotton wool inside. Taking bedding as an example, bedding generally consists of tire material and outer textile fabric, and tire material can be divided into flocking tire and loose fiber. The structure and shape of loose fibrous pad tire core are not fixed, and it is easy to flow and contract, and its thickness is uneven. In order to tightly fix the outer fabric and the inner core of the quilt and make the thickness of the quilt uniform, the outer fabric and the inner core are stitched in parallel straight lines or patterns (including stitching). This process of increasing aesthetic feeling and practicality is called quilting, and the quilt or mattress after sewing is called quilted quilt and quilted mat. In the past, quilting products were basically done by hand, and the products were mainly quilted quilts and quilted mats. The difference between them and the bedding used in general families lies in the addition of a quilting process, and the operation procedure is to sew first and then quilt. Using the workshop-style processing method of thousands of households, the output is low, the pattern consistency is poor and the operation process is complicated. 15 years ago, mechanical multi-needle quilting machine entered China, with high output and good consistency, but the pattern was simple and changed little, so it was impossible to reverse cloth and make plate. Mainly composition, mainly processing lining and quilt core.

1.2 intermediate quilting technology

At present, some manufacturers still use hand-made and mechanical quilting machine for quilting production. Because these two methods have their own shortcomings, they are gradually replaced by more advanced computer quilting production technology. Compared with the traditional mechanical quilting machine, the computer quilting machine has broken through the function of only typing simple patterns in half coordinates. Under the control of precise computer system, computer quilting machine can perfectly handle all kinds of complex patterns compiled in the whole coordinate system, and the production speed, mechanical performance, noise pollution and other indicators are incomparable to previous mechanical machines. Using advanced computer quilting technology can improve labor productivity, reduce costs and realize the automation of quilted products. Manufacturers can produce more practical and beautiful products to meet the needs of the masses and gain profits for their own development. Therefore, it is an inevitable trend for computer quilting machine to eliminate mechanical quilting machine.
