High Viscosity Protective Clothing Hot Melt Glue

   What are the common problems of protective clothing Hot Melt Adhesive?

Hot Melt adhesive Pressure Sensitive Adhesive

General protective clothing in the glue pressing process problems are:
The fabric is not temperature resistant, the process of pressing glue produces holes, can not stick, feel no viscosity, and easily unglue the next day after pressing.
These reasons will lead to the failure of pressing glue and the test water pressure is not enough. Comprehensive analysis of the following schemes for reference:
First, fabric holes in the production process solution:
1, replace the low temperature hot melt strip;
2, reduce the temperature, if the lower temperature can not stick, please refer to 1;
3, reduce the air volume;
4, slow entry time;
5, accelerate the withdrawal time. 3, 4, 5 can effectively avoid fabric burning.

Second, the solution can not stick:
1, understand whether the gun temperature is low, the gun temperature did not reach the melting point of the strip. The test is simple take a piece of cotton, press it down, and if it sticks it's not a temperature problem. If it does not stick, the gun temperature test can be appropriately increased. If the test has holes, you can refer to the first type of solution.
2, the material is incompatible. At present, there are many kinds of rice birds in the market, and dozens of fabrics that can not be stuck have been tested. This phenomenon needs to find a hot melt adhesive enterprise with research and development ability, oriented research and development.
3, fabric composite film is currently based on PE and TPU, you can consult the fabric manufacturer what material is covered. Coated PE material can generally use high and low temperature EVA strips, polyolefin strips, and other classes. TPU film then choose PU rubber strip.

Third, after sticking, after a few days a pull on the glue solution:
The coating of the fabric has been surface treated, and the bonding will appear false. The bond will be fine for a few days, then it won't work. This kind of phenomenon is very common in the hot melt adhesive industry. Solution, can choose low temperature fat soluble high rubber strip, so easy to penetrate.
