In a second aspect, the invention discloses an anti-pilling knitted cashmere and wool fiber product, which is prepared by the preparation process of the anti-pilling knitted cashmere and wool fiber product.
The invention has the beneficial effects that:
1. the invention discloses a preparation process of a knitted cashmere and wool fiber product, which comprises the step of weaving mixed chemical fibers and cashmere and wool fibers into a single-layer externally-bound chemical fiber cashmere and wool product by using a double-eye yarn feeding nozzle or a wide yarn nozzle, or the step of weaving the outer layer into the chemical fibers and the inner layer into a double-layer cashmere and wool product of cashmere and wool by using a double-faced jacquard process. The existing cashmere and wool products in the market rarely perfectly combine chemical fibers with cashmere and wool, but the invention adopts a yarn nozzle or double-sided jacquard process, so that the prepared cashmere and wool products have better elasticity and skin-friendly effect, can avoid the hair falling phenomenon caused by poor fitting property of the cashmere and wool and the chemical fibers, have the advantages of better moisture retention and air permeability, easy dyeing and good dye adhesion, have good application prospect, and can be used for various close-fitting or external-wearing clothes.
2. The diameter of the traditional wool fiber is generally 20-30 microns, the traditional wool fiber belongs to thicker fiber, when the diameter of the traditional wool fiber is the same as that of other fiber, the stacking structure is more fluffy, the stacking structure is related to single fiber with unique crimp shape, the cohesion force between the wool fibers is relatively small, therefore, the wool fiber is easy to slide out of the surface of the fabric, and then the wool fiber is fluffed, and once fluffed, the wool fiber is entangled with each other under the action of static electricity, so that balls are formed on the surface of the fabric; the diameter of cashmere fibers is 12-16 mu m, and compared with wool fibers, the cashmere fibers are small in fineness, short in length and small in number of curls, so that the fibers are smaller in cohesive force in yarns, more exposed fluff is generated, and the fibers are smooth and glutinous, and easily slip from fabrics under the action of external force to generate fluff dropping and pilling. Therefore, the invention aims at the characteristics of the wool fiber and the cashmere fiber, and the surface of the wool fiber and the cashmere fiber is treated to improve the cohesive force among the fibers and eliminate the capacity of generating static electricity, so that the product prepared from the fibers achieves the anti-pilling effect.
3. The invention also carries out surface pretreatment before modifying the wool fiber and the cashmere fiber, wherein, the surface pretreatment process comprises the steps of cleaning, extracting and plasma surface treatment of the wool fiber and the cashmere fiber in sequence, wherein, the cleaning is to remove impurities on the fiber surface and extract and remove lipid substances on the fiber surface, and the plasma surface treatment is to cause the fiber surface to generate various physical and chemical changes and generate etching to obtain the fiber with more pores on the surface, so that the subsequent modifier can be more adsorbed on the surface.
4. The modified wool fibers and the modified cashmere fibers are obtained by processing modified treatment fluid, and the main component of the modified treatment fluid is modified tungsten diselenide nano powder. The modified tungsten diselenide nano powder is obtained by modifying thymol and grafting ferulic acid, and is specifically obtained by firstly performing adsorption grafting on the tungsten diselenide nano powder and thymol under the action of a coupling agent to obtain thymol/tungsten diselenide nano powder, then reacting the thymol/tungsten diselenide nano powder with ferulic acid, and enabling hydroxyl on the surface of the thymol/tungsten diselenide nano powder to be combined with a carboxyl bond in a ferulic acid molecule through condensation reaction, so that the modified tungsten diselenide nano powder is fixed on the thymol/tungsten diselenide nano powder to form the modified tungsten diselenide nano powder.
In the modified tungsten diselenide nano powder, the tungsten diselenide nano powder is a graphene-like two-dimensional material, and the main structure of the modified tungsten diselenide nano powder is formed by connecting an upper layer of selenium atoms and a lower layer of selenium atoms with a middle layer of tungsten atoms, so that the modified tungsten diselenide nano powder has a larger specific surface area and stronger adsorption performance; thymol is a natural extract, widely exists in plants, has certain antiseptic, antifungal and antioxidant properties, but has stimulation effect on skin, eyes and mucous membrane; ferulic acid is also a natural extract, and can scavenge free radicals and promote the production of free radical scavenging enzymes. The invention adopts the tungsten diselenide nano powder as a carrier, so that the thymol and the ferulic acid react and are grafted on the carrier, thereby the tungsten diselenide nano powder has certain oxidation resistance and corrosion resistance, and the side effect of the thymol on human body stimulation is also solved. After the modified tungsten diselenide nano powder is used as a modifier to modify wool and cashmere, experimental results show that the wool and the cashmere not only increase certain antibacterial property and oxidation resistance, but also greatly improve the defect of pilling of the wool and the cashmere by detection, and probably the cohesive force between fibers is enhanced by a reaction product of thymol and ferulic acid loaded by the modified tungsten diselenide nano powder, and the antistatic property is also enhanced.
