Further, the weft yarn of the double-deck stereo tissue layer upper strata and lower floor is one, three interval settings.

A kind of spray drawing apparatus preparation method of aramid fiber enhancing fabric polyethane conveyer belt, comprises the following steps：A) fabric Sizing；B) primary coat；C) coating is cast to set；D) reverse side primary coat；E) the coating of polyurethane-coated layer.

The beneficial effects of the utility model are：

1) a kind of Novel conveyer belt is provided for painting industry, belt intension is high, deformation is small；

2) noise that conveyer belt reverse side is produced with contact surface can be effectively reduced by strengthening the design of 3/1 twill of fabric；

3) surface abrasion resistance is high, chemically-resistant agent cleaning ability is strong；

4) it is thin to convey tape thickness, light-weight, peel strength is high；

5) manufacture craft is easy, is readily produced control；

6) compared to other conveyer belts used at this stage, the utility model finished product price is relatively low, has very strong market Competitiveness.

7) production cycle is shortened, saves a large amount of human and material resources, while avoids attaching process in original production to go out Existing production uncertain factor, such as：Binding temperature control is unreasonable to be easy to cause the stripping of product laminating layer low, so as to cause product It is easily delaminated, is not durable in use；Tension force is irregular in fitting is easy to cause product arch camber, alice phenomenon to produce, and influences The flatness of product, so as to influence air brushing effect and quality.The new technological process of production is short, easily operated, and the factor of production influences Small, product quality can be greatly improved.
