the sewing machine is still good for sewing straight seams, the prior art cannot be solved, and the functions of the sewing machine are basically the same as those of the automatic sewing machine;

process requirements

The woolen sweater garment piece can be woven by a flat knitting machine and also can be cut by grey cloth of a circular knitting machine. However, the knitted pieces produced by any method must be sewn up to form a woollen sweater of wearing value, and this process is also called a ready-made garment, i.e., a process of connecting the separated pieces and accessories of the woollen sweater, such as the front body, the back body, the sleeves, the collar, the front fly, etc., into a woollen sweater by using stitches. The quality of the sewing quality directly influences the quality of the woolen sweater, the wearing performance of the woolen sweater is influenced, and the woolen sweater plays an important role in embodying the style characteristics and appearance modeling of products.

Because the styles of the woolen sweaters are varied, the adopted raw materials are various, and the sewing equipment, the technology and the method are also various, the requirements for sewing various woolen sweaters are different. However, in general, there are several basic requirements that should be addressed during the sewing process.

Firstly, the adopted suture line should be matched with the piece to be sewed

The thread used for sewing the garment is collectively called a sewing thread. The color of the sewing thread for sewing the woolen sweater is the same as that of the clothes to be sewn. Otherwise the appearance is affected when the stitches are exposed on the surface of the woolen sweater. For jacquard products and color matching products, the color with a larger proportion of the colors at the seams is generally selected as the colors of the seams, and for individual woolen sweaters with the seams as decorations, the colors of the seams can be selected according to the requirements. The thickness of the thread has a great influence on the sewing quality, and the sewing quality is determined by combining the thickness of the garment piece wool yarn, the adopted sewing equipment and method and the stitch density, the sewing is difficult when the thread is too thick, the appearance and the fastness are influenced when the thread is too thin, and the thread is generally thinner or better than the garment piece wool yarn in order to smoothly perform the sewing. In order to ensure that the garment pieces and the seams are consistent in terms of performance, color, etc. during long-term wear, it is desirable that the material of the seams be the same as or similar to the material of the garment pieces. In addition, the suture should have high strength and strength uniformity, smooth surface and uniform fineness, moderate and uniform twist, softness and high elasticity. The thread winding should be tight, smooth, burr-free, knot-free and scratch-free to reduce broken ends and broken needles.

Secondly, the sewing mark needs to be smooth and can embody the style characteristics

The stitches are seams formed by joining stitches. Because the woolen sweater has larger extensibility, the edge loops of the woolen sweater can be prevented from being loosened. During sewing, the elasticity and a certain dissapability of the parts of the garment piece must be ensured, so that the selected seams must have the extensibility and elasticity suitable for the parts and parts to be sewn, and the marks must be accurately aligned. The stitches are smooth and inconspicuous. When machine sewing is adopted, the tightness of the upper thread and the bottom thread is moderate, so that the garment piece is not wrinkled and has small deformation. The stitch density is equal to or more than the density of the piece to be sewn, and the stitch density is uniform and has no needle holes. When the end of the stitching needs to be reinforced, the sewing is carried out by returning to the vehicle for reinforcement, and the thread end is hooked into the clothes piece in a smooth manner, so that the surface is clean and free of thread ends. In addition, the style and the shape of the woolen sweater are realized by the shape of the garment piece, and the style and the shape of the woolen sweater are also reflected by the matched stitches, so that the stitch positions are required to be correct, the transition is smooth and smooth, and the tightness is required to meet the shape requirement and reflect the design intention.

Thirdly, the stitching has enough fastness

The stitch fastness refers to the service life of the woolen sweater in the wearing process of repeated stretching and friction without damaging stitches. The stitch firmness is affected by the stitch structure and elasticity of the stitches, particularly in the areas that are often stretched during wear, and the elastic stitch structure and stitches must be used to ensure that the stitches do not stretch apart and open during use. The seam strength is directly related to the seam strength, and the stronger the seam used, the stronger the seam formed. In general, when the stitch density is high, the strength is also high, but when the stitch density is too high, the strength is rather reduced, and the consumption of the suture is increased. The wear resistance of the stitches also has a great influence on the fastness of the stitches, and almost all the stitches are rubbed when the woolen sweater is worn, especially on the parts with high stretchability. The friction between the sewing material and the sewing thread, and the human body or underwear and the sewing thread occurs more frequently. Practice has shown that the damage of the seam is mostly caused by grinding off the seam, so that the seam must be wear resistant.

Specification selection

The woolen sweater looping is carried out on a linking machine, the machine number of the linking machine is matched with that of a woolen sweater knitting machine, and the following table can be referred when the machine number of the linking machine is selected. When looping, the horizontal looping consumption is 2-3 courses, the longitudinal looping consumption is 1-2 needles, and a worsted woolen sweater is usually sewn by using worsted homochromatic wool yarn of 28 multiplied by 2tex to 31 multiplied by 2tex (tex, linear density unit) as a suture line; for sewing chemical fiber products, clothing blank materials are often used as stitches. The phenomenon of needle pattern deflection and needle overlapping is not allowed when the mouth is sleeved. When the shoulder-hanging sleeve is used for closing shoulders and sleeves, the elongation of the shoulder seam is more than 110%, and the elongation of the shoulder-hanging seam is more than 130%.

Linking machine specification selection

The adaptability of the machine in the existing machine device is poor, and each machine can only be used for making a needle-type sweater. When another needle type sweater is to be made, another machine corresponding to the needle type of the sweater, such as an 8-needle sweater made by one machine, is used for processing the sweater by using the 8-needle machine, when the 8-needle sweater is made, a 12-needle sweater is made by using the 12-needle machine, and if more than ten needle types of clothes are available, more than ten machines are used.

Secondly, the faller in the current machine is undetachable, needs to the needle, and the lacing film operation takes time and to operating personnel higher requirement. The machine needle plate can not be detached and only single sewing can be carried out, because the needle plate is fixed with the machine, and the size of the needle plate, the length of the needle and the running distance of the needle of each machine are different, so that the needle plate can not be replaced.

In summary, the disadvantages of the existing machines are: the needle plate is a fixed circular structure, is difficult to align needles and is difficult to be applied to different needle-type sweaters.

Disclosure of Invention
