Description
Technical Field
[0001] The present invention relates to the technical field related to the production of textile functional fibers, and in particular to a production method and production equipment for textile functional fibers. Background Art
[0002] The development of textile functional fibers is a symbol of the progress of modern fiber science. Functional fibers refer to new fibers that have special functions in addition to the physical and mechanical properties of general fibers, which enable the fibers to have functions such as sterilization and deodorization. Reference publication number CN217757941U is a non-woven fabric strip production equipment, which uses a first roller, an immersion component and a composite component. After the inner layer of non-woven fabric is immersed in liquid by the immersion component, the upper layer of non-woven fabric and the lower layer of non-woven fabric are further bonded together by the composite component. At the same time, the bonded non-woven fabric is sprayed with liquid, pressed, etc., so that the non-woven fabric can be subjected to multi-layer composite, toughening and weight increase, etc., which are modification processes that are beneficial to loading functional substances. The operation is stable and the adaptability is strong. The pressing force strength, conveyor belt speed and liquid spraying amount can be adjusted. The operation method is simple, the disassembly and assembly are convenient, and the production efficiency is high. It has the function of collecting the treatment liquid in real time and can be recycled, which is environmentally friendly. It can accurately control the amount of impregnation liquid used to ensure the uniformity of the treatment effect, which is helpful to develop high-quality multi-layer composite non-woven fabric products and improve product added value and economic benefits. The production equipment has a simple structure, low maintenance cost, and is easy to maintain and promote. However, there are still the following problems: When the above-mentioned device is actually used, the material is coated through the immersion component. However, the material will absorb the liquid inside the immersion component during the coating process, thereby reducing the liquid inside the immersion component. As a result, when the liquid is reduced, it is necessary to manually add liquid to process the subsequent material, which makes the process more cumbersome and inconvenient.
[0003] Reference publication number CN218065767U discloses an efficient drying device for polyester yarn production. The device starts an electric heating tube through an air outlet, which heats the air inside the shell. Then, a negative pressure fan is started, which draws the hot air inside the shell into the inside of a connecting pipe. The connecting pipe transports the hot air to the air outlet and then sprays it to the outside through an air outlet. The hot air can be evenly sprayed through the air outlet, increasing the contact between the polyester yarn and the hot air, improving the drying efficiency, and making the drying more uniform. However, the following problems still exist: In actual use of the above device, although the drying effect is achieved by blowing hot air toward the material, the air outlet is fixed inside the device, which results in a low drying area of the air outlet, leading to a poor drying effect.
