Embodiment Construction

[0006] The preparatory process is to soak and pretreat the hat tire. At this time, soak the hat tire in a special running water tank with a temperature of 98°C for 30 minutes, and reverse the direction once every minute. The bath ratio is 1 (fabric): 20 (solution) , soak until its pH value is neutral. The pre-treatment process is the core part. Put the cap tire in a solution tank with a temperature of 60-80 ° C and add a commercially available fabric pretreatment agent PT for 5-10 minutes, so that the main substance of the felt cap tire, that is, the wool fiber, is denatured, thereby Enhance the absorption capacity to cap tire; Now the liquid pump speed is 30 revs / min, the bath ratio is 1: 20-30, and the dosage is 3-4%; dehydration to its water content is less than 40% after this with the drier. In the dyeing process, the cap tire is dipped in the dyeing tank at a temperature of 70-80°C for 10-15 minutes. The dye itself is a colored substance that is completely insoluble in wa...
