(3) and (3) carrying out hydroentanglement: inputting the cotton web into a spunlace device for spunlace to obtain a formed non-woven fabric;
(4) dewatering and drying: dehydrating the formed non-woven fabric and drying by using an oven;
(5) winding into a roll: winding the dried formed non-woven fabric into a roll;
(6) cutting and packaging: and cutting and packaging the rolled formed non-woven fabric, and storing the packaged formed non-woven fabric to a warehouse.
Preferably, the specification of the PVA fiber raw material in the step (1) is: the length is 35-42mm, and the fineness is 1.1-1.7 dtex. The adoption of longer PVA fiber is beneficial to forming a net and reinforcing, and ensures the strength of the finished product.
Preferably, in the step (2), the rotation speed of each carding roller of the carding machine is controlled, the rotation speed of the main tin wheel per minute is 1000-. Prevent the over-high rotating speed from causing flying.
Preferably, the automatic hopper of control TF atmospheric pressure stores up cotton volume in step (2), sets up the wind pressure: the upper bin is 400-450Pa, and the lower bin is 800-900 Pa. The lower wind pressure reduces the fiber density of the automatic cotton box of TF atmospheric pressure, prevents that too much compaction cotton layer of fibre storage from causing the card cotton.
Preferably, the temperature of the oven is set to 95-105 ℃ when the product is started in the step (4), and the temperature of the oven is raised to 115-125 ℃ after the vehicle speed is normal. The temperature is gradually increased, and the cloth surface is prevented from hardening and crisping due to the suddenly increased temperature.
The invention has the following beneficial effects: the PVA non-woven fabric processed by the PVA fiber through the spunlace non-woven fabric production line has the characteristic of dissolving in water at a certain temperature, ensures normal use and is convenient for post-treatment; meanwhile, PVA also has the characteristics of high strength, high modulus, low elongation, wear resistance, acid and alkali resistance and the like, so that the use strength of the non-woven fabric is ensured; in the actual production process, when the PVA raw material is adopted to produce the non-woven fabric, cotton and fly are easier to block than tencel and other materials, so that the production efficiency is ensured while the cotton and fly are prevented from being blocked by adjusting the air pressure in the TF air pressure automatic hopper and the rotating speed of the main tin wheel of the carding machine.
