Cashmere is called "soft gold" and "fibre diamond". The warmth of cashmere is 2 to 3 times that of wool. Cashmere is close to the human body. It has good warmth and comfort, so it is loved by many people. Where? Here is the introduction:
There is cashmere on the goat. The sheep is only wool. On a goat, only a few tens of grams of cashmere can be collected each year. It takes 3 to 5 goats to weave a cashmere sweater.
The cash collected from these goats is produced by selecting wool → washing, sterilizing → combing → dyeing → drying → tying → combing → spinning → plying and twisting → winding, and the basic raw material of cashmere sweater is produced. Come out, the production process of cashmere sweater is roughly divided into the following steps: raw material inspection → flat knitting machine → sheet inspection → sleeve mouth → hand seam → seam inspection → light inspection → shrinking hair → hair selection → light inspection → repair inspection → whole Hot → Booking → Finished Product Inspection → Sampling → Packaging → Outbound.
1. Cashmere yarn raw materials are put into the factory, and the test and inspection department promptly samples the samples, and tests the items such as the calibration line density and the uniformity of the yarn count, and meets the requirements before they can be put into production. 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.
2, cashmere sweater knitting equipment, cashmere sweater type, knitting is the main process of cashmere sweater production, its knitting machinery has two kinds of ordinary flat knitting machine and computer flat 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. Generally, the flat knitting machine is divided into two types: thick needle and fine needle. Therefore, the cashmere sweater is divided into different needle types: cashmere sweaters can be divided into the following needle types according to the knitting needle type: 16 needles, 14 needles, 12 needles, 9 needles, 7 needles, 5 needles, 3 needles, and rods. According to the organizational structure is divided into: plane, twisted flowers, drawing, jacquard, intarsia, embroidery, printing, and others. According to the type of cashmere sweater weaving can be divided into two categories: full-form and cut-shaped, but most of them are fully formed.
3, woven film inspection, after the machine produced on the flat knitting machine, the machine must pass the film-by-piece inspection to meet the requirements before entering the garment 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 test piece should be checked after the piece is 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.
4, the mouth, this part is to take the individual pieces of the film inspection by machine stitching method to connect together to form a ready-to-wear.
5, hand sewing, some of the inconvenience of cashmere sweaters, the details of the machine seams should be stitched by hand stitching, such as collars, cuffs, buttons and other auxiliary materials, the effect of hand sewing will be better.
6, sewing plate inspection, all the pieces and accessories after the stitching, in order to prevent the interface is not stitched firmly, the needle is not stitched or the seam is not beautiful, etc., need to check again. Stitch requirements: The stitching of the cashmere sweater should have the same stretch and strength as the shirt body, except for the pocket. In principle, the suture must be the same as the raw material, color and yarn density of the cashmere sweater. The stitching of the carded product and the upper thread of the machine seam should be made of combed cashmere yarn. The bottom line of flat seams, overlocks, etc. must not be too high, soft, elastic, smooth and strong enough.
7, light inspection, a key step of inspection, put the cashmere sweater on a special mold, through the light can more clearly see the needles, needles and other sputum on the cashmere sweater, in order to find problems in time to solve.
8, washing water shrinking hair, shrinking hair is a wet finishing process, is the use of cashmere fiber's shrinking characteristics, so that the fiber is wet and wet, the scales are soft and soft, under the action of friction, the performance of short velvet, feel full, improved appearance . The additives, temperature, bath ratio, time and other parameters used for the fluffing should be used properly. In the process of fluffing, the degree of shrinkage should be checked midway, and the suede standard should be compared to prevent excessive fluffing.
9, sorting the hair, select some of the hair and heterochromatic fibers attached to the cashmere sweater, so that the cashmere sweater looks more tidy.
10, light box inspection, this method of light inspection is the same as step 7, the purpose is to detect the cut monofilament caused by tools such as tweezers during the selection process.
11, repair inspection, repair all the missing needles that can be repaired, flower needles and broken monofilaments.
