Description
Technical Field
The invention relates to clothes, in particular to an antistatic overcoat finishing process.
Background
The overcoat is an overcoat which is worn outside the clothes and has a wind-cold defense function, and the length of the overcoat is up to the waist and below. The overcoat fabric has a plurality of types, and the high-grade overcoat fabric has wool fabric. The natural characteristic of the wool fiber enables the wool overcoat to have incomparable comfort, thick texture and good heat retention. When the textile material is rubbed by the outside to generate a large amount of charges and cannot be quickly dissipated, static electricity is generated. Due to the existence of the scale layer, the wool fabric has hydrophobicity, rough and uneven surface and higher friction coefficient, and is easy to generate static electricity, especially in a dry environment.
If the surface of the fabric is provided with a large amount of static charges, the fabric is easy to adsorb dust in the air and has serious influence on the human health. In order to improve the antistatic performance of the wool overcoat, the wool overcoat needs to be subjected to antistatic finishing.
Chinese patent publication No. CN105696343A discloses an antistatic finishing method for wool fabric, which comprises the following steps: firstly, adding water into a finishing agent to prepare a dipping solution, then putting the fabric into the dipping solution for padding, wherein the padding rate is 70-80%, finally washing for 2-3 times, and dehydrating and drying; the finishing agent comprises the following components in parts by weight: 20-25 parts of polyoxyethylene diamine, 12-15 parts of N- (phosphonomethyl) glycine isopropylamine, 6-9 parts of benzyl trimethyl ammonium chloride, 2-4 parts of sodium carboxymethyl starch, 10-14 parts of linolenic acid, 2-5 parts of acetone, 1-6 parts of acrylamide, 4-9 parts of fibraurea stem powder, 3-6 parts of polyvinyl alcohol, 15-17 parts of styrene, 5-8 parts of sodium fatty acid, 3-6 parts of sodium citrate and 1-8 parts of aluminum sulfate.
By the antistatic finishing method, the antistatic agent is applied to the surface of the fiber, so that the hydrophilicity of the fabric is improved, static is prevented from accumulating on the surface of the fiber, the charge releasing capacity of the fabric is improved, and the wool overcoat has antistatic property. However, with the cleaning and washing of the overcoat, the antistatic property of the overcoat is gradually deteriorated and is not durable enough to be improved.
