C. 100kg polyurethane wet resin is joined in the mixture that step b formed, stir 30 ~ 40 minutes, deaeration 40 ~ 50 minutes;
Step 2: wet method bass is produced:
Being coated with by the slurry that in step one, deaeration has been formed scrapes on woven fabric fiber, immersing mass percentage concentration is again solidify in the dimethylformamide in water of 18 ~ 22%, then through at least one squezzing operation, more a kind of wet method bass after carrying out washing and drying, is obtained;
Step 3: dry mixed is prepared burden:
By even for high-speed stirred after the mixing of 100kg polyurethane dry method color-change resin, 15 ~ 20kg dimethyl formamide, 15 ~ 20kg butanone, 15 ~ 20kg toluene, 0.5 ~ 1.0kg auxiliary agent and 3 ~ 5kg toner, mixing time 10-15 minute;
Step 4: dry method veneer:
Being coated with by the dry method slurry prepared in step 3 scrapes in forming dry method veneer with in the release liners of flower pattern, then by adhesive be adhered on dry method veneer under the condition of 90 ~ 110 DEG C in temperature by the wet method bass in step 2, be separated through super-dry heel release liners, obtain a kind of semi-finished product;
Step 5: water is rubbed: the semi-finished product in step 4 are divided into 30 ~ 0 meters/section, is placed with in the boarding machine of 40 ~ 60 DEG C of clear water, rubs line 20 ~ 40 minutes, and after taking out, squezzing is dried, bake out temperature 70-90 DEG C;
Step 6: ready-made clothes presses:
After the semi-finished product of step 5 gained are made clothes, need to darken, have the position of burnt sense by 80 ~ 100 DEG C of flatirons at clothes arbitrarily, pressed for 5 ~ 10 seconds.
As a further improvement on the present invention, dimethyl formamide and mill base high-speed stirred 90 minutes in described step a.
As a further improvement on the present invention, the mixed liquor of 240 order nylon wires to dimethyl formamide and mill base is used to filter in described step a;
B. by 100 ~ 120kg dimethyl formamide and 20 ~ 30kg wood powder mix and blend 30 minutes, then fully swelling 35 minutes, then add the mixture filtered in step a and stir stand-by;
C. 100kg polyurethane wet resin is joined in the mixture that step b formed, stir 40 minutes, deaeration 45 minutes.
As a further improvement on the present invention, the speed of a motor vehicle of described step 2 is at 18-20 rice/min, and the speed of a motor vehicle of step 4 is at 20-25 rice/min.
As a further improvement on the present invention, electric iron is adopted to carry out flatiron process in described step 6.
The invention has the beneficial effects as follows: the present invention is by carrying out localized hyperthermia's flatiron on the dry method overlay coating surface using polyurethane dry method color-change resin to make, change product structure, reach color change in various degree, there is burnt sense effect, such that clothes is more attractive in appearance, air, fashion.
