Two Factors Affect The Quality Of Raw Materials

　　 1. Natural factors

It mainly includes species, sex, age, health condition, living area and production season.

(1) types of fur making Raw material skin The original animal species have great influence on the use value of raw materials. Therefore, in the acquisition of fur, the "variety difference" or "type difference" is stipulated. The standard value of the first grade quality is usually used for a certain variety (commodity). Usually the value is 100%. Then the ratio of the other varieties is compared with the standard varieties, and the ratio is "variety difference". The difference between varieties is mainly reflected in the price difference, for example, the fur industry series commodity leopard skin as an example, the leopard skin variety difference is: the money leopard skin is 100%, the AI leaf leopard skin is 65%, the moire leopard skin is 50%, the red spring leopard skin, the sesame Leopard skin, the leopard skin and the Mo Yun skin are all 20%.

(two) the quality of fur of different sex in the same sex is also quite different. In the acquisition of Heng Shu silt, there is a "male to female ratio". The price of the first class leather is 100%, then the price of the two grade is equal to the ratio of the leather to the sleeves. The ratio is the ratio of the mother to the skin. The unit price of the first class leather is multiplied by the ratio of the mother to the skin, and the price of the first class skin is 100%, and the mother's skin is 80%.

(three) animal bells are usually produced in young animals with light fur, thin skins and small tenderness, but meticulous plates. Fur produced by young animals is of better quality; furry fur produced by old animals is thick and long, light is poor, and the skin board is thick, hard and rough.

(four) in living areas, this will affect the raw materials. quality Have a combined effect. In general, the same raw material is produced in cold regions with large width, plush, thick hair, glossy gloss, slightly lighter skin, slightly thicker skin, and higher value. In tropical areas, the fur is generally small in size, slightly short and coarse in plush, darker in color, slightly thicker in skin and low in use value. However, the skin with pattern or spots is clear and good quality in the warmer areas. Fur produced in mountainous areas, loess areas, black soil areas or sandy soil areas has regional characteristics and different quality.

(five) during the production season, it can reflect the stage and inherent quality of the plush and skin plates in the process of removing the wool under the influence of climatic conditions and other living conditions. Therefore, the season is directly related to the quality of raw fur. The influence of production season on the quality of raw fur is by no means a mere condition, but a comprehensive influence of many conditions on the quality of animals. In different seasons, there are obvious differences in the color, density, thickness, length, thickness and strength of the fur coat. Therefore, in order to grasp the time of skin picking in time, the fur maturity should be identified before slaughtering the fur animals.

　　 Two, human factors

Peel from the animal body and begin to enter the raw material skin. light industry Before processing, various factors that cause quality changes include production methods, initial processing, preservation, storage and transportation.

(1) production methods include proper slaughter, reasonable capture and stripping. Proper slaughtering and peeling methods can reduce and avoid the occurrence of injuries such as knife holes, tracked knives, lack of materials, and so on. In the process of peeling, if the force method can not be or not pay attention to, it is easy to cause all kinds of disability.

(two) feeding and management. At present, China's mink, fox, raccoon dog, beaver and other fur animals, the critical period for winter hairs growth is 9 October. Protein content should be increased in the diet, and the protein with sulfur containing amino acids should be used. If there is a lack of fluffy nutrients in the winter hairy growing diets, the molting is delayed, the growth of winter hairs is slow, the bottom hair is empty, the length of the hair is uneven, or the hairs are bent. Especially in this period, large amount of rabbit head and rabbit skeleton can be used to seriously affect the quality of fur.

(three) initial processing includes peeling, scraping, washing, drying, and planting. Processing must be done according to technical requirements and purchase specifications. The planting plates used for the last use shall be uniformly planted by the state.

(four) store and keep the fur storehouse must be well ventilated. Pay attention to the temperature, steaming degree and humidity of the storeroom, so as to prevent moth and rat bite. Control the occurrence of accidents such as flail flying, hair loss and decay.

(five) packaging and transportation must be packed according to the requirements. The bundle must be strong, and it should not be exposed to rain or sunshine during transportation. Good fur can be lost because of improper protection or quality defects during transportation.
