A making method of wear-resistant TPU drop stitch fabric

The technical problem to be solved by the invention is to provide a preparation process of TPU wear-resistant drop stitch fabric, through the improvement of the preparation process of double wall fabric, a space cloth with higher wear-resistant performance can be obtained.

In order to solve the above technical problems, the technical scheme adopted by the invention is as follows:

The preparation process of TPU wear-resistant drop stitch fabric includes the following steps:

Step 1: evenly apply adhesive on the upper surface of the mesh layer and the lower surface of the lower mesh layer of the spatial mesh;

Step 2: the adhesive layer of the net cloth layer and the lower net cloth layer coated with the adhesive in step 1 is upward, preheated to 140-160 ℃ for curing;

Step: 3: the adhesive layer surfaces of the pre heated web cloth layer and the lower web cloth layer in step 2 are respectively extruded and cast to adhere to the TPU film, and the adhesion temperature of the TPU film is 140-160 ℃;

Step 4: cool the net cloth layer and the lower net cloth layer which are respectively adhered with TPU film to obtain the TPU wear-resistant space net cloth.

The adhesive layer is prepared from the following weight parts of raw materials:

Polyester type PU adhesive 90-110 parts; bridging agent 6-10 parts; butanone 5-20 parts; toluene 5-10 parts; the application amount of the adhesive is 100-120g / m2;

The TPU film is prepared from the following weight parts of raw materials:

95-110 parts of TPU resin, 2-7 parts of TPU smooth masterbatch, 0-10 parts of TPU color masterbatch and 15-40 parts of flame retardant masterbatch.
