Description

Technical Field

[0001] This invention belongs to the field of textile manufacturing technology, and particularly relates to a method for antistatic treatment of garments. Background Technology

[0002] Polyester fabrics are widely used in clothing due to their high strength, good elasticity, good thermoplasticity, good abrasion resistance, and good corrosion and light resistance. However, because polyester fabrics have low moisture absorption and poor electrical conductivity, they easily generate static electricity upon friction. Static electricity makes the fabric prone to pilling, easy to get dirty, and can stick to the skin or other clothing, causing discomfort when worn. This is especially true in winter, when the fabric is in contact with the skin, causing discomfort. This is because the large molecules of polyester fibers are covalently bonded, cannot ionize, and cannot transfer electrons. In addition, their low polarity and high hydrophobicity make it difficult for charges to dissipate, leading to a tendency for charge to accumulate. Therefore, it is necessary to improve the antistatic properties of polyester fabrics to enhance wearing comfort. Summary of the Invention

[0003] This invention provides a method for antistatic treatment of garments, aiming to solve the above-mentioned problems.

[0004] This invention is implemented as follows: a method for antistatic treatment of garments, comprising the following steps:

[0005] Washing: Place the garment in a drum washing machine, add washing solution, set the temperature to 40-50℃, spin speed to 15-20r / min, liquor ratio to 1:30, and wash time to 20-30min;

[0006] Dehydration: Dehydrating the washed garments;

[0007] Drying: Dry the dehydrated garments at a temperature of 50-90℃;

[0008] Garment absorbent finishing solution: Apply the antistatic finishing solution to the dried garment;

[0009] Drying: Dry the garments that have absorbed the finishing solution at a temperature of 60-90℃;

[0010] Baking: After drying the garments that have absorbed the finishing solution, bake them at a temperature of 140-170℃ for 1-3 minutes.

[0011] Cooling: Place the baked garments in a cooling room to cool.

[0012] Preferably, the water washing working solution includes a penetrant JFC with a concentration of 0.5-2 g / L;

[0013] The penetrant JFC helps the subsequent antistatic finishing liquid to fully penetrate into the garment material. It has fixed hydrophilic and lipophilic groups that can be oriented on the surface of the solution, which can significantly reduce the surface tension. Its hydrophilic groups are polar and can combine with moisture in the air to form a monomolecular conductive layer, which allows the generated static charge to leak out quickly and achieve the purpose of antistatic.

[0014] Preferably, the antistatic finishing liquid comprises the following raw materials by mass percentage: 5-15% of a block copolymer of polyethylene oxide and polyethylene terephthalate, 0.3-1% of Pingpingjia O, and the balance being water. The combination of the block copolymer of polyethylene oxide and polyethylene terephthalate and Pingpingjia O allows the antistatic agent Pingpingjia O to be evenly distributed in the block copolymer, thus forming a conductive pathway. The block copolymer fully integrates with the garment, thereby giving the garment excellent antistatic properties.

[0015] Preferably, the pH of the finishing solution is adjusted to 5-6.3.

[0016] Preferably, the method for applying the antistatic finishing liquid to the garment is as follows: the finishing liquid is atomized in an atomizing device, and the compressed air pressure is adjusted to 3-6 kg / cm². 2 The process involves atomization for 10-30 minutes at a machine speed of 15-25 rpm. The solution absorption rate is calculated to be 100%, and the liquid content of the garment is controlled to be 60-90%. The atomization process creates uniform, fine finishing liquid microbeads that are directly sprayed onto the garment surface. A concentration difference exists between the atomized and unatomized sides of the garment. Through the penetration of the liquid, finishing liquid molecules diffuse with water molecules towards the unatomized side, forming a concentration gradient of the finishing liquid in the direction perpendicular to the normal of the garment. The side of the garment that comes into direct contact with the skin during wear remains unfinished, retaining its original fiber composition and maintaining its wearability.

[0017] Preferably, the antistatic finishing liquid further includes the following raw materials by mass percentage: 3-5% modified zein solution.

[0018] Preferably, the modified zein solution comprises the following raw materials in parts by weight: 25-35 parts zein, 2-4 parts polyglycerol, 1-2 parts citric acid, and 80-100 parts ethanol at a concentration of 80-90%. The zein is biodegradable and biocompatible, has a bottom surface energy, and possesses unique film-forming properties, enabling it to form a thin film on the garment surface. It also exhibits antistatic properties. By grafting hydrophilic polyglycerol onto zein, the surface hydrophilicity of zein is altered, modifying it into an amphiphilic protein. Its lipophilic groups extend into the interior of the garment, while its hydrophilic groups extend to the surface. The hydrophilic groups are arranged facing the air, forming a monomolecular conductive layer, thus improving antistatic performance. Its lipophilic groups can firmly bind to the garment. By adding citric acid, the elongation of zein is increased, allowing it to cross-link with other components to form a network structure, improving the mechanical properties of the antistatic layer. This makes the antistatic layer less susceptible to damage from washing and other methods, resulting in good antistatic durability.

[0019] Preferably, the modified zein solution is prepared as follows: first, zein is mixed with half of the ethanol and stirred for 30-50 minutes to obtain a zein dispersion; then, polyglycerol, citric acid and the remaining ethanol are added to the zein dispersion and ultrasonically mixed for 20-30 minutes to obtain the modified zein solution.

[0020] Preferably, the ultrasonic mixing temperature is 60-70℃ and the ultrasonic power is 300-400W.

[0021] Compared with the prior art, the embodiments of this application have the following main advantages:

[0022] The antistatic treatment method for garments provided by this invention involves first washing with water and adding a penetrant, which helps the subsequent antistatic finishing liquid to fully penetrate into the garment material. Then, an antistatic finishing liquid containing a block copolymer of polyethylene oxide and polyethylene terephthalate is used for finishing, introducing antistatic groups and reacting with the fibers to form a network cross-linked polymer, reducing the friction coefficient of the fabric, reducing the surface resistance of the fibers, and accelerating the dissipation of static charge, thereby achieving the effect of reducing static electricity.
