Description
Technical Field
The invention relates to the field of wig production, in particular to a long-acting antibacterial shape memory wig hairline treatment process.
Background
Hair is a multicellular fibrous material composed of keratin as a main body (about 95% of dry hair mass), and keratin is composed of amino acids. Each hair consists of an epidermal scale layer, a cortical layer and a medulla layer. The outermost layer of the hair is a cuticle scale layer, and is usually composed of 2-4 layers of scales. The cortex layer is the main body of hair and is composed of several layers of prismatic keratinocytes, and the cells contain a large amount of pigment particles. Cortical cells have a diameter of about 2 to 3 μm and consist of a number of basal fibrils, microfibrils and macrofibrils. The diameter of the base fibrils is only about 2X 10 < -3 > mu m, and the base fibrils are composed of 2-3 strands of alpha-helical angle proteins. The medullary layer is located in the center of the hair and consists of 2-3 layers of shrunken cube-shaped keratinocytes. The hair ends and vellus hair are free of medulla.
Currently, the quality of wig materials in the market mainly comprises 3 types: whole hair (i.e., 100% hair fibers), chemical hair (i.e., 100% synthetic fibers), and mixed hair (i.e., hair fibers + synthetic fibers). As a raw material of the hair product, the synthetic fiber is not limited by resources, has been industrially produced, has low cost and low price, and has become the main stream of the hair product market. In addition, various colors and varieties can be changed in time according to market demands, and the added value of the product is high. In order to make the performance of synthetic fibers more similar to that of natural hair, new wig fiber varieties have been developed or various modification methods of existing fibers have been studied. Synthetic fibers commonly used in the production of hair products are polyvinyl chloride (PVC) based fibers, polyacrylonitrile (PAN) based fibers, polyester (mainly PET) based fibers, polypropylene (PP) based fibers, protein based fibers, and the like.
In the wig shaping process, physical heating or chemical practical method is mostly adopted, and the heat setting is to heat treat the fiber by using the thermoplastic property of the fiber so as to keep certain size and shape. The heat setting is an important ring in the wig bending production process, and the technological process comprises pipe winding, kang feeding, pipe dismantling. The winding tube is formed by winding the hair on the spring by using an aluminum tube according to the process standard of the product, and is wound on the aluminum tube in a winding way, and the winding tube is uniform in thickness and neat and symmetrical in edge pattern. The pipe winding mode is divided into a double-flower mode and a double-flower mode. The kang feeding house is a technical core part of heat setting, and setting of process parameters (such as setting temperature, setting time and the like) directly determines setting effects. The pipe disassembly is to disassemble the aluminum pipe of the shaped semi-finished product without unhairing, twisting and tail scattering, and classify and place the aluminum pipe. Heat setting is classified into dry heat setting and wet heat setting. The dry heat setting is to set the fiber in a setting cabinet after winding the fiber tube in dry hot air environment, and the setting method is only suitable for synthetic fiber. The hair fiber after dry heat setting has poor curl fastness, short hold time of curl form and is easy to damage by external force. To solve this industry problem, hair fibers are usually shaped in a hot and humid environment (such as hot steam) during production, and the internal structure of the fibers is changed by means of moisture action to achieve a desired shaping effect. The curl fastness of the hair fiber processed by the wet heat setting process is correspondingly improved. From the heat setting process, it can be seen that some of the thermal properties of the fibers have a direct, important effect on hair product processing, particularly the thermal transition temperature of the fibers, which determines the heat setting temperature of the filaments when processed into wig products.
At present, in the shaping processing of the curly hair in the wig production process, the existing processing technological process has the problems of longer shaping time, poor durability and stability of the shaping effect of the curly hair, and the existing production equipment needs to manually apply an aluminum pipe to wind the hair on the spring, and then send the hair into a kang room for processing, so that the processing efficiency is low and the shaping effect is poor. Therefore, we propose a long-acting antibacterial shape memory wig hairline treatment process.
