the same tent cloth material as in example 1 was treated by the prior art, the treatment process was as follows: grey cloth → padding treatment liquid → steaming (130 ℃, 30min) → drainage (85 ℃, 10min) → neutralizing by glacial acetic acid cleaning (100 ℃, 10min) → drainage (85 ℃x10 min) → hot water washing (95 ℃, 10min) → drainage (85 ℃) → alkali decrement treatment (liquid alkali 20G/L, 130 ℃, 30min) → drainage (85 ℃) → hot water washing (100 ℃, 10min) → drainage (85 ℃) → hot water washing (90 ℃, 10min) → drainage.
Detection example:
the tent cloths treated in the above examples 1, 2, 3 and 1 were subjected to strength tests and sensory tests, and the steam consumption and water consumption per 1 ten thousand meters of the tent cloth raw material treated were recorded;
and (3) strength test: testing the tensile strength of the cloth by using a strength testing machine;
sensory test: and (3) testing the pilling grade by using a fabric pilling instrument, and testing the whiteness by using a whiteness tester.
TABLE 1 test results
As shown in the detection results in Table 1, the tensile strength, the pilling grade and the whiteness of the tent cloth in the examples 1, 2 and 3 are all obviously higher than those of the tent cloth in the comparative example 1, the amount of steam consumed for treating 1 kilometer of tent cloth raw material in the examples 1, 2 and 3 is 1t, and the amount of water consumed is 3.5t, while the amount of steam consumed for treating 1 kilometer of tent cloth raw material in the comparative example 1 is 5t, and the amount of water consumed is 3.5 t.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
