Wool knitting is different from cotton knitting. It is directly woven with yarn in the process of flat knitting. Like we make sweaters, a wool yarn cannot be continuous from beginning to end. Therefore, in this process, workers will use knotting to connect each yarn. Generally speaking, a knitted sweater cannot be without knots, but for a good quality knitted sweater, its knots are always hidden in invisible places, such as side seams and underarms. Another aspect of the workmanship quality of knitted sweaters is on the flower feet, which are called Ming Narrowing needles (shouming flowers) in the industry, and mostly appear at the neckline and hanging shoulders. Generally speaking, no matter whether the needle is narrow or the sleeve is good, in the knitted sweater, it is always more valuable than the selvage. There are some sweaters that we can see when we open them inside. The joints between the parts and the sleeves are the same as woven or cotton knitting. In fact, this cannot be classified as a good team in the field of wool knitting. A little further, there is an appropriate distance between the price of sweaters with sleeves and sweaters with hem in foreign trade exports. From the point of view of the fabric surface of a sweater, the stitching is a very important point. It is the little braids we see, they need to be uniform and the same size. If the thickness of the needle path is uneven, it means that the knitting equipment has not been adjusted properly during the loom process, or the yarn may have thick and thin hairs. According to the supply of knitted fabrics, knitted sweaters are divided into two types: hand-hooked or hand-punched and woven. The flexible and diverse hand-hooked tricks cannot be replaced by knitting machines. The output value is low, so the price is expensive. The hand-hooks are mainly distributed in the Shantou area. Knitting machines are commonly used. Needle types are: 1.5 needles, 3 needles, 5 needles, 7 needles, 9 needles, 12 needles, 14 needles, 16 needles, 18 needles, etc. , the finer the sliver, the finer the yarn used, the higher the price, the higher the process requirements and the higher the processing fee).
