(1) Wool knitting production process:
Wool yarn entering the factory → raw material inspection → preparation project → knitting project → garment engineering → finished product inspection → packaging into the warehouse wool yarn raw materials into the warehouse, the test laboratory in time to extract the sample, the yarn density of the yarn count, evenly Projects such as degrees are inspected and meet the requirements before they can be put into production.
Most of the yarns entering the factory are in the form of hank yarns, which must be subjected to a winding process to make them suitable for knitting of flat knitting machines. The braided semi-finished pieces are inspected and entered into the garment process. The garment workshop is mechanically or hand-stitched according to the process requirements. According to the characteristics of the product, the garment process also includes finishing processes such as napping, fluffing and embroidering. Finally, after inspection, ironing, shaping, re-testing, sorting and packaging.
(2) The deviation of the linear density of the raw materials for raw material inspection, the uniformity of the strip, the moisture regain and the color fastness, directly affect the quality of the product. Therefore, when the raw materials are inspected and problems are found, the process can be revised in time, and technical measures are taken to prevent the quality of the finished products from being affected.
(3) The purpose of the preparation process and the various wool yarns sent to the sweater factory, mostly in the form of skein, can not be directly knitted on the knitting machine; at the same time, there are various defects and impurities on these yarns. Affect the quality and yield of the knitting. Therefore, the purpose of the preparation process is to wind the skein into a package form to meet the needs of yarn unwinding in the weaving production; to remove defects and impurities on the surface of the yarn, and to wax and soften the wool yarn; according to the process requirements The wool yarn is twisted and combined to increase the yarn fastness and increase the thickness of the wool fabric.
When winding the yarn, the elasticity and elongation of the yarn should be kept as much as possible, and the tension is required to be uniform and the unwinding is smooth.
(4) Wool-knitted knitting equipment, knitting type and garment inspection Xiashan garment factory is the main process of woolen sweater production. The knitting machine has two kinds of flat knitting machine and round knitting machine. Since the flat knitting machine has relatively many advantages, such as the method of increasing or decreasing the number of stitches to weave the garment piece suitable for the human body, it is possible to form the garment without cutting, thereby saving raw materials, reducing the number of processes, changing the pattern, and changing the variety. Convenient and so on, so sweater companies mostly use flat knitting. However, due to the characteristics of fast speed and high output, the circular machine is getting more and more attention from some manufacturers.
According to the type of sweater weaving, it can be divided into two types: full shape and cut shape. The full-form knitting is to adopt the needle-removing and needle-retracting process to achieve the desired shape and size of each part. After knitting, it can be ready for garment without cutting, and is used for weaving high-grade products made of animal fiber. The cutting type can be divided into partial cutting and overall cutting. The partial cutting is generally performed by using a stepped copying needle (needle-needle-needle) process on the shoulder and the sleeve of the mountain, and then partially cutting to obtain the desired shape size and cutting loss. The amount is small, and the output can be improved. This method is mostly used to weave medium-to-high-end products such as fine-pitch fabrics and jacquard tissues. The overall cutting generally refers to obtaining the desired shape and size through the cutting form after being knitted into a piece of cloth by a circular machine. In this way, the cutting loss is large, and it is generally applied in low-grade raw materials. After the pieces produced on the flat knitting machine of Zhongshan Garment Factory are dismantled, they must pass the piece-by-piece inspection to meet the requirements before entering the garment manufacturing process. The contents of the piece inspection include the specifications of the piece (ie the length of the piece, the length of the rib, the number of rotations of the folder, the number of stitches, etc.), the weight of the piece and the appearance quality, and the appearance quality includes the missing needle, the flower needle, and the blank Silk and so on. The density and specifications of the spring and summer clothing inspection pieces should be carried out after the pieces are fully retracted. During the knitting process, the longitudinal stretching of the threading plate, the hanging hammer, etc., combined with the tension during knitting, makes the density of the lower back piece, the size of each part and the actual requirements of the finished product greatly different, so after the machine is removed The piece of clothing, after standing for a certain period of time, does not retract to reflect the actual density and specifications. However, this method of natural retraction (relaxation and contraction) takes a long time. In practice, various external pressurization methods, such as agglomeration, contracture, and crimping, are often used to quickly retract the pieces. Spring and summer clothing (5) garment process 1. The garment process process sweater is stitched to connect the collar, sleeve, front and back body of the garment, as well as buttons, pockets and other auxiliary materials, and some are also modified by wet finishing methods and embroidering methods to make the garments have certain styles and characteristics. . The general process flow for garments is:
Sewing piece → semi-finished product inspection → fluffing → keyhole button buckle → ironing stereotype → garment inspection 2. The ready-to-wear process requires autumn and winter clothing (1) stitching requirements: the stitching of the sweater should have the corresponding stretch and strength with the shirt body. In addition to the pocket, the elongation rate is usually required to reach 130%. In principle, the stitching must be the same as the raw material, color and yarn density of the sweater. The stitching of the carded product and the upper thread of the machine seam should be made of combed yarn. The bottom line of flat seams, overlocks, etc. must not be too high, soft, elastic, smooth and strong enough.
(2) Requirements for fluffing: The fluffing is a wet finishing process. It is a fluffing property of animal fibers. After the fibers are wetted by wet heat, the scales are soft and soft. Under the action of friction, the fluff is expressed, the feel is full, and the appearance is improved. . The fluffing is applied to carded products such as cashmere sweaters, rabbit sweaters, and sheepskin sweaters. The combed products can also be washed at a normal temperature or for a short period of time or lightly velvet to improve the appearance. The additives, temperature, bath ratio, time and other parameters used in the downsizing of spring and summer clothing must be properly selected. Otherwise, if the fluffing is excessive, the batch products will be felted and cannot be remedied. In the process of fluffing, the degree of shrinkage should be checked midway, and the suede standard should be compared to prevent excessive fluffing.
(3) Ironing and shaping: The purpose of ironing is to make the product stereotype, maintain the style characteristics, the appearance is flat and firm, and the hand feels comfortable. When ironing, put the sweater on the sample to meet the specifications. The temperature of the sweater is generally 120 ° C ~ 180 ° C, to prevent "hot yellow, aurora" during operation. During the ironing process, the sweater is subjected to a drafting process to accelerate the cooling and reduce the humidity. Autumn and winter clothing has been more and more shaped by steaming machine (flattening machine) in recent years. It is composed of automatic lifting upper plate and fixed lower ironing plate. The setting time (spray time and residence time) is 4s. Between 30s, the efficiency is much higher than manual ironing.
(6) Inspection of finished products Inspection of finished products is a comprehensive inspection before leaving the factory. There are three special processes in the inspection of sweaters, including re-measurement, finishing and classification. The contents include appearance quality (dimensional tolerance, appearance defects), physical indicators (single weight, needle ring density), inner and outer packaging.
During the finishing process, a small number of defects that are not in the retreat range, such as oil stains, residual grass clippings, and seams that can be removed, can be repaired at any time.
