One cashmere sweater requires 3 to 5 cashmere goats
With the gradual improvement of quality of life, the cashmere, which known as "soft gold" or "fiber diamonds," has gradually entered the lives of ordinary people, especially the cashmere sweater. Thanks to the good extensibility and elasticity of cashmere sweater, it is warm, comfortable, and so preferred by more and more people. Then, how dose cashmere sweater be produced? Here is a brief introduction: a mature goat can only be taken to 30 to 50 grams of cashmere, so one cashmere sweater needs 3 to 5 cashmere goats.

Production process
Selecting wool → washing cashmere → carding → dyeing → drying → co-hair → comb spinning → spinning → twisting → winding
Cashmere yarn - the basic raw material for cashmere sweater is produced in this way.

The next step is the production of cashmere sweater, it can be divided into the following steps:
delivering cashmere yarn into the plant → raw material inspection → flat knitting machine →film inspection → linking→ hand sewing →sewing inspection → light inspection→ Shrinking→ choosing hair → light inspection → repairing → ironing → calibration → finished product inspection → sampling → packaging → delivery

1.Delivering cashmere yarn into the plant.
After storage, the test laboratory department takes inspections of linear density and yarn evenness, only qualified materials can be put into production. The reasons for raw materials testing is to test the linear density deviation, evenness, moisture regain and color fastness of the raw materials, which can directly impact product quality. Therefore, any problem of the raw materials can be found and revised timely, taking technical measures to prevent the impact of the quality of finished products.

2.Cashmere sweater knitting equipment, cashmere sweater type.
Knitting is the main production process of cashmere sweater, the knitting machine can be divided into two types: ordinary flat knitting machine and computer flat knitting machine.
Because the flat knitting machine has many advantages, such as increasing the number of stitches, we can knit the clothing piece adaptable to the human body. It can save the raw material and reduce the process.
Easy to change varieties, so most enterprises use sweater knitting machine. Generally, there are two kinds of flat knitting machines and fine needles.

So, cashmere sweaters can be divided into different types according to needles:

According to needle, cashmere sweaters can be divided into the following types : 16-pin, 14-pin, 12-pin, 9-pin, 7-pin, 5-pin, 3-pin, knitting needle.

According to the organizational structure, cashmere sweaters can be divided into: flat, twist flowers, pumping strips, jacquard, intarsia, embroidery, printing, and other.

According to knitting type, cashmere sweaters can be divided into full shape and cut-shaped two categories, but full shape is the major type.

3. Film inspection.
Cut-partsmust be tested piece by piece to meet the requirements in order to enter the garment manufacturing The testing includethe size of the piece (the length of the piece, the length of the rib, the number of revolutions, the number of the needles, etc.), the weight of the piece, and the quality of the appearance such as the missing needle, flower pin, silk and so on.
The density and specification testing of the cut-parts should be conducted after they are fully retracted. During the knitting process, the longitudinal stretching of the threading board, hanging hammer, etc., combined with the tension when knitting, change the actual condition of the cut-parts, so these parts need to be stand for a certain period of time to return to their origin density and size. However, this natural retraction (relaxation contraction) approach needs a longer time, so the actual operation often takes a variety of external pressure methods, such as the group shrinking, shrinking, curling and other methods to make rapid retraction of the garment

4.Linking, hand sewing, sewing inspection, light inspection, shrinking.
This process is to connect all qualified clothing pieces using the machine suture method to form a garment.
Some inconvenient parts of the cashmere sweater need to be sewed by hand sewing, including cloth collar, cuffs, buttons, and other auxiliary materials, hand sewing will be better.
In order to prevent the interface is not stitched and stitches off the needle or stitched unsightly and so on, it is need to check all cut-parts and accessories again. Stitching requirements: cashmere sweater seam should be with corresponding stretch and strength, in addition to the outside pocket. In principle, the suture must be same as the cashmere sweater raw materials, color, and yarn line density. Carding products and suture seam line should use combed cashmere yarn. Flat seam, bag sewn and other bottom lines can not have too high twist, but they should be soft, flexible, smooth, and have enough strength. A key step of inspection, the set the cashmere sweater in a special mold, clearly see the missing needles, needles and other flaws of the cashmere sweater through the lights, so as to promptly identify problems in time and to solve. Shrinkage is a wet finishing process, which takes advantages of cashmere fiber’s milling characteristics, wetting and heating the fibers to expend the and soft them, and eventually improve fullness and appearance. The additives, temperature, bath ratio, time, and other parameters used in shrinkage must be properly selected. In the process of shrinking, the degree of shrinkage must be half-checked, compared to suede surface to prevent excessive velvet.

5.Choosing hair, light inspection, repairing, ironing, calibration, calibration.
Removing the roans and heterochromatic fibers attached on the cashmere sweater to make it looks clean.
The light inspection is the same as the step 4, the purpose is to detect ad pick monofilament. Repair all the leaks, needles, and broken monofilaments that can be repaired.
The purpose of ironing is to make products stereotypes, and to maintain style characteristics, the appearance of flat crisp, and comfortable feel. When ironing, set the sweater on a model, and avoid"hot yellow, Aurora." during the process. After ironing, a cashmere sweater will be on its basic shape. Then, attach the label if needed, so that a complete real cashmere sweater is born.

6.Finished product inspection, sampling,packaging, delivery.
There will be a comprehensive inspection of the finished products before leaving the factory. Cashmere sweater inspection has re-testing, sorting, and classification three specialized processes, the contents of which include appearance quality (dimensional tolerance, appearance defects), physical indicators (single weight, needle density), etc. In the finishing process, a small number of defects, such as oil stains and seams, can usually be repaired at any time. After repairing, all the products should be no problem, but in order to ensure a high-quality product, it is necessary to take some samples for re-test. After all the products are qualified, the cashmere sweaters will be folded as required, and then put into the bag and flat into the carton. After the above 16 steps, can the cashmere sweater be a qualified product, and then become a commodity. After reading the above production process, you now know why cashmere sweater is called "Golden Flower" or "soft Gold ".
