Introduction of flushable spunlaced nonwovens
Collapsible spunlace non-woven fabric, also known as ES non-woven fabric, is a new type of environmental protection material.
Polypropylene (PP) particles are used as raw materials for dispersible spunlaced nonwovens, which are melted, extruded and sprayed at high temperature to become raw materials for production.
The production process of spunlace non-woven fabric can be dispersed
1. Raw material selection and pretreatment
Polypropylene particles were selected and pretreated. The purpose of pretreatment is to disperse the particles evenly, prevent bonding and improve quality.
2, melt extrusion
The pre-treated polypropylene particles are fed into the melt extrusion equipment. The melt extrusion equipment can control the temperature, speed, pressure and shape of the melt according to the production needs.
3. Spray thinning
The molten polypropylene liquid is refined through the spray head. In this process, water spray surrounds the melt nozzle inside and outside, making the melt suddenly cool at the moment of ejection. At the same time, the high-speed water flow breaks up the ES capillary fibers to be shaped, making them have fiber shape and completing the capillary fiber molding.
4. Transverse coating
After the capillary fibers are formed, they need to be coated laterally to thicken the fibers. Horizontal coating can be used nozzle, filter, roller, coating type and other equipment.
5. Spines
Use a spunling machine to strengthen the transverse thickened non-woven fabric one or more times. After spunlaced strengthening, the product has a certain mechanical strength.
6. Scatter the net
After the spunlace reinforcement treatment, the spunlace non-woven fabric can be dispersed for scattering treatment. In the process, high-pressure water is used to superimpose the fibers on top of each other to form a network.
7, winding, cutting, packaging
After the completion of production, the spunspunned non-woven fabric can be dispersed according to the production needs, such as winding, cutting and packaging, and the final product leaves the factory.

In the production process, it is necessary to control the indicators of the flushable spunlace non-woven fabric to ensure that the product quality meets the requirements. The main indexes include appearance quality, physical indexes, mechanical properties, water absorption time, dissolved substances in water, etc.

Diffusible spunlaced non-woven fabric is a new environmental protection material, which has been widely used in various industries. Understanding the production process of the flushable spunlaced nonwovens can help people better grasp the characteristics and application prospects of this material. The production process introduced here is a general production process, the specific production process also needs to be adjusted according to the different products.

ES non-woven fabric is widely used in medical, health, home, filtration and other fields because of its characteristics of disintegrability, moisture absorption, air permeability, light texture, soft and easy to handle.
