B, elongation at break≤18 ± 3%;

2), the check of material:

A, to the material in storehouse set by step 1) in parameter test;

B, the material that does not meet the step 1) condition can not use;

C, can come into operation at the material of step 1) design allowed band;

3), material is twisted thread:

The twist of a, material is: 130 ± 5T/M (number of turns of each meter sth. made by twisting is 130 ± 5 circles);

B, twist with the fingers to being: S to or Z to;

After c, the completion of twisting thread, the twist is detected once again;

4), weave:

A, warp yarns shrinkage 8 ± 0.5%;

B, broadwise weave shrinkage 6%, drying and shaping 3.26%;

After c, faultless cloth wove, whether the above data of check were correct in 2 hours;

D, warp-wise such as defective adjusts in addition;

E, broadwise such as defective adjusts in addition;

5) typing, impregnation:

A, the typing of needle plate thorn, pressure roller air pressure 1.8 ± 0.5at, warp-wise weight-adding hammer 9 ± 0.5Kg; 168 ± 5 ℃ of temperature, walking speed 13 ± 0.5m/min, following water typing grey cloth fabric width 90-95cm; Typing back fabric width 85-95cm; Weave shrinkage is 3.26%, and the typing back data of testing are so that revise percentage elongation during impregnation at once;

B, needle plate thorn impregnation, pressure roller air pressure 1 ± 0.5Kg, warp-wise weight-adding hammer 12 ± 0.5Kg, 168 ± 5 ℃ of temperature, walking speed 13 ± 0.5m/min, typing cloth width of cloth 85-95cm, the anti-granny rag width of cloth is 85-95cm during impregnation; Before impregnation, draw together the glue in the acupuncture only earlier, anti-anti-avulsion thorn causes substandard cloth.

The present invention compares the outstanding advantage of prior art:

1, the product of the present invention's production is low through the broadwise distortion, equates through the broadwise distortion, is difficult for twisting stable performance, long service life;

2, the product stable gas pressure of the present invention's production, resiliency is high;

3, product of the present invention is as the automobile brake chamber leather cup.
