Hair washing is a process of removing impurities such as lanolin, sheep sweat and sand in raw hair by combining mechanical and chemical methods to obtain clean hair.

By combining mechanical and chemical methods, the impurities such as lanolin, sheep sweat and sand soil in the raw hair are removed to obtain the process of washing the hair. Unremoved dust and lanolin in the washed wool will affect the subsequent process and the quality of the finished product. The needle cloth of carding machine and the needle board of carding machine are easy to be blocked by mud, difficult to draw when spinning, more broken ends, more broken ends of loom, high consumption, poor dyeing, etc. Therefore, wool washing is a very important process in wool spinning engineering. Lanolin is a complex mixture of higher fatty acids and higher monools. Fatty acids can be saponified and removed easily in alkaline medium. Alcohols are insoluble in water and not easy to saponify in alkaline media, so they can only be washed away by emulsification. Sheep sweat is mainly inorganic salt, of which potassium carbonate accounts for 75~85%, soluble in water. The solution of sheep sweat is alkaline and can saponify the fatty acids in lanolin. The nature of soil impurity in wool has a great relationship with washing wool, and the impurity content of wool varies greatly in different regions. The fine wool of Xinjiang, China contains more compounds such as calcium and magnesium than Australian wool. Such as silicate, carbonate, chloride, sulfate and other soluble in water, the generation of calcium, magnesium, iron plasma, so that the water quality becomes hard, affect the washing effect, if the use of synthetic detergent effect is better.

Wool washing principle

The basic functions of washing agent are: adsorption wetting to reduce the surface tension of aqueous solution; Emulsification and dispersion, so that the washed oil impurities are stably suspended in the solution; Solubilizing effect, can increase the solubility of the substance in the lotion, and easy to remove from the wool; No damage to wool, no corrosion of equipment, etc. There are many kinds of hair washing agents. In the past, soap and soda ash were used to wash hair. Synthetic detergents have been widely used since the 1960s. Synthetic detergent has good wetting, emulsification, decontamination, solubilization and foaming properties in washing, and is better than soap in resisting hard water and less damage to fibers at high temperature. In order to prevent alkali damage to wool, non-ionic synthetic detergent can be used and salt, sodium sulfate as auxiliary, called neutral wool washing. When using synthetic detergent to wash hair, adding ammonium sulfate as auxiliary, called ammonium alkali washing hair. Ammonium sulfate plays a neutralizing role in the washing solution to prevent alkali damage to wool, and the ammonia generated can saponify fatty acids, which is conducive to the durability of the washing effect. In wool washing solution, lotion wetted wool, to dissolve and sheep sweat and soluble impurities, lanolin free fatty acid in the saponification, saponification of lanolin, alcohol and not dissolve in water were surrounded by a lotion and adsorption dirt gently, under the effect of temperature and mechanical split, broken, emulsion become colloidal particle separation with wool, steady suspended in solution, so as to achieve the aim of clean wool.

Process equipment

Hair washing method is VERY MUCH, WATER AND ALL kinds of detergent is called emulsified hair washing method, with organic solvent is called solvent hair washing method. There are also many types of wool washing equipment. The rake washing machine is widely used in emulsifying wool washing, and is often associated with hair opening and hair drying equipment, called opening washing and drying combined machine. In addition, there are jet washing machine, roller washing machine, ultrasonic washing machine and so on. There are also various types of solvent hair washing equipment, but the cost is high, the safety protection is complex, less used.

The opening washing and drying machine is composed of three parts: opening, washing and drying. The main function of the opening part is to loosen and remove impurities, loosen the bulk raw hair and remove a large amount of sand impurities. The main function of the wool washing part is to remove lanolin, sheep sweat and sand impurities. The number of slots of the wool washing machine depends on the quality of the wool washed, the amount of fat sweat and soil impurity. Generally, there are 3~5 slots. 4~5 grooves are used for fine wool with more fat. 5 grooves are used for fine wool with more fat and soil impurity produced in China. In the 5-groove washing machine, the first groove generally does not add lotion, which plays the role of soaking wool and washing away part of the sand impurities; The second and third tanks were washed with lotion specified by the process to achieve the purpose of lanolin removal. Rinse with clean water in tank 4 and 5. The wool in the washing tank is driven by the washing rake, so this machine is called rake washing machine. The wool out of the final wash tank pressure roller still contains about 40% moisture, and is sent to the drying part for drying, so that the net wool meets the specified moisture return requirements. The drying part adopts circular net drum dryer, generally composed of 3~6 circular net drums, using hot air convection heat transfer to achieve the purpose of drying wool, can also use a single curtain type multiple heating dryer. The washing process has a great relationship with the quality of washing wool. In addition to the selection of lotion, the concentration of lotion, the temperature of lotion and the water used for washing wool also have an impact. To wash the raw hair containing more fat, the dosage of lotion should be increased compared with the washing with less fat; Lanolin containing more alcohols is difficult to wash, it is necessary to increase the amount of lotion, the temperature of lotion should be higher than the melting point of lanolin. For the refractory lanolin whiskers, the washing liquid temperature is increased, but the temperature is too high, which will cause the wool to produce felt, yellowing and rough feeling. The general washing temperature is 45~55℃. Neutral wool washing because the use of synthetic lotion will not damage the wool, can be appropriate to increase the temperature of the lotion, generally with 48~60℃. Apply soft water to wash hair, otherwise it will consume more lotion.
