Glue for cloth glue dispenser and preparation method thereof

Abstract

The invention discloses glue for a cloth glue dispenser and a preparation method of the glue. The glue for the cloth dispenser is prepared from the following components in percentage by mass: 61.5 to62.0 percent of a polyurethane prepolymer, 26.0 to 26.5 percent of an ethylene vinyl acetate copolymer, 11.0 to 11.5 percent of tackifying resin, 0.2 to 0.4 percent of a filler and 0.1 to 0.3 percentof an auxiliary agent. The disclosed glue is suitable for an automatic cloth glue dispenser. The temperature and pressure needed in a mold pressing process are low, high temperature and high pressureare not needed, energy consumption can be further reduced, the production cost can be further reduced, damage to cloth is avoided, the problems that the cloth becomes hard and discolors due to high temperature do not exist, and the application range is wide. A whole garment product produced by the glue matched with an automatic cloth glue dispenser is free of any sewing stitches, more convenient to clean, comfortable, soft, good in hand feeling, good in air permeability, firm in bonding and good in stability, the overall production efficiency is improved, and then the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of adhesive manufacturing, in particular to a glue for a cloth dispensing machine and a preparation method thereof. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, the shipment of clothing is increasing, and people's requirements for the quality of clothing are also getting higher and higher. At present, there are two conventional manufacturing processes for clothing. The first is the traditional process of sewing; the second is the process of laminating fabrics with TPU polyurethane film. [0003] However, both of these two processes have considerable disadvantages. The first sewing process requires many types of equipment, high requirements for manual operation skills, and many working hours for workers. The production cost is high, and the sewing process is adopted. The clothing products produced have obvious stitch...

Problems solved by technology

[0003] However, both of these two processes have considerable disadvantages. The first sewing process requires many types of equipment, high requirements for manual operation skills, and many working hours for workers. The production cost is high, and the sewing process is adopted. The garments produced have obvious stitches at the joints of the fabrics, and the comfort level is low when people wear them, which will produce obvious strangulation marks, and even scratch the leather clothing, leading to inflammation

The second TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) polyurethane film bonding process method, on the one hand, the stability of the process is not good enough, and the operation skills of employees are required to be high during operation, and the cost of the film is also low. Higher, and the clothing products produced by this process are equivalent to adding a layer of film between the cloth and the cloth, which affects the air permeability that the cloth should have, and the product feels poor and hard; on the other hand, TPU polyurethane In the process of laminating the film, it is necessary to melt the film before the cloth can be firmly bonded together. If the processing temperature is not enough and the film is not fully melted, the bonding between the cloth will be insufficient, and there will be It will lead to the risk of degumming, so it is usually necessary to use high temperature and apply a certain pressure to achieve it. The generally used process parameters are temperature 170-180°C and pressure 4-5kg / m 2 , some even need to reach 200°C, such temperature will cause irreversible damage to the fabric structure of the material, making the fabric hard and discolored, and the energy consumption of production is high, which increases the cost of production and is not conducive to environmental protection
