Technical Field
[0001] This utility model belongs to the field of nonwoven equipment technology, specifically relating to a hydroentanglement head for processing synthetic leather. Background Technology
[0002] In the textile industry, hydrospinning machines are commonly used processing equipment. The hydrospinning head is one of the most important components of the machine, and the quality of the product largely depends on its stability. With continuous product iteration, hydrospinning machines need to process an increasing variety of fibers, some of which are very tough. For example, when processing recycled cowhide synthetic leather, higher water pressure is required for the hydrospinning head to penetrate the fiber. However, in actual use, it has been found that pressurized water easily forms turbulence within the hydrospinning head, causing uneven water pressure in certain areas. This results in uneven pressure ejected from the hydrospinning head, leading to streaks on the surface of the recycled cowhide synthetic leather and severely affecting product quality. Currently, most companies in the industry operate hydrospinning heads under low water pressure conditions, unaware of this problem.
[0003] In view of the above, it is necessary to design a hydroentangling head for processing synthetic leather that is simple in structure, low in cost, capable of eliminating turbulence, and able to operate stably under high water pressure. To this end, the applicant has made a beneficial design, and the technical solution described below arises from this background. Utility Model Content
