The Primary Quilting Technique
According to the explanation given By the Grand Dictionary of Chinese Language, quilting is a method to fix several layers of fabric, cotton together by using a long sewing needle. Take the bedding for example, it is generally composed by two parts:? the inner wadding material and the outer fabrics, and the inner wadding materials can also be divided into two types: one type is loose, the other type is fixed. The shape of the Loose wadding is not fixed, easy-flow, and non-uniform thickness. ?In order to make outer fabric and inner wadding closely fixed, and uniform the bedding thickness, we find out a method to quilt outer fabric and inner wadding in a straight line side-by-side or decorative patterns, which increased the sense of beauty , this practical processes known as the quilting. We call the bedding or mattress produced by the quilting machine is quilted bedding or mattress. In the past, the quilted products are usually hand-made, and the product is mainly quilted bedding and mattress, and the difference to ordinary families bedding lies in the method they used. Their operating procedure is to quilt after sewing. The drawbacks of using thousands of households workshop-style processing approach is low yield, poor consistency of the patterns, complex process. 15 years ago, the mechanical multi-needle quilter enter into Chinese market, which have much higher yield, and consistency is also better, but the pattern is simple, and can not make big changes, neither the cloth can be inverted, and have no drawing versions. Therefore, these machines are mainly used for processing beddings and fixing the wadding..
　　The Intermediate Quilting Technique
Nowadays some manufacturers still use handmade and mechanical quilting machines for production. Due to there are shortcomings of above two ways of production ,it has been progressively replaced by more advanced computerized technology quilting machine. Compared with the traditional mechanical quilting machine, The modern quilting machines have made a breakthrough, that is for the traditional mechanical quilting machine in the bar only half of its simple patterns are available. In the precise control of computer systems, computerized quilting machines are able to handle the entire coordinate system on the establishment of a variety of complex patterns perfectly. In the parameter of production speed, mechanical properties, noise pollution and so on, all the previous mechanical machines can not match with the computerized quilting machine .
