Production process of spunlace non-woven fabric

Production process of spunlace non-woven fabric

Spunlace non-woven fabric is composed of multiple layers of fibers, and its application in daily life is relatively common. The following Wenzhou Xinyu non-woven fabric XinYu Non-woven will tell you about the production process of spunlace non-woven fabric. Process:

1. Spunlace nonwoven process:

1. Fiber raw material → opening and mixing → carding → interweaving and laying → drafting → → pre-wetting → positive and negative spunlace → finishing → drying → winding water → treatment cycle

2. Fiber raw material → opening and mixing → carding and messy web → → pre-wetting → positive and negative spunlace → finishing → drying → winding → water treatment cycle

Different web-forming methods affect the vertical and horizontal strength ratio of the finished spunlace non-woven fabric. Process 1 adjusts the vertical and horizontal strength ratio of the fiber web better, and is suitable for the production of spunlace synthetic leather base fabric; Process 2 is suitable for water entanglement. Production of thorns and health materials.

2. Pre-wetting

The formed web is fed into a hydroentanglement machine for reinforcement, first with pre-humidification.

The purpose of pre-wetting is to compact the fluffy fiber web and remove the air in the fiber web, so that the fiber web can effectively absorb the energy of the water jet after entering the spunlace area, so as to strengthen the fiber entanglement effect.

3. Spunlace

After the pre-wetted fiber web enters the spunlace area, the water jets of the water jet nozzle of the spunlace head spray out multiple fine water jets, which are shot vertically to the fiber web. The water jet displaces a part of the surface fibers in the fiber web, including vertical movement to the opposite side of the fiber web. reverse side. Under the dual action of the direct impact of the water jet and the rebound of the water flow, the fibers in the fiber web are displaced, interspersed, entangled, and cohesive, forming numerous flexible entanglement points, thereby strengthening the fiber web.

Four, dehydration

The purpose of dehydration is to remove the remaining water in the fiber web in time, so as not to affect the entanglement effect of the next spunlace. When the amount of water retained in the fiber web is large, it will cause the dispersion of water jet energy, which is not conducive to fiber entanglement. After the spunlace process is completed, the moisture in the fiber web is reduced to a minimum, which is beneficial to reduce the drying energy consumption.

5. Water treatment and recycling

The water consumption of the spunlace nonwoven production process is very large. When the output reaches 5 tons/day, the water consumption is about 150m3~160m3 per hour. In order to save water and reduce production costs, about 95% of the water must be recycled after water treatment.

The above is the production process of spunlace non-woven fabrics. Wenzhou Xinyu Non-woven Fabric Co., LTD. has a complete and scientific quality management system, mainly producing non-woven fabrics, non-stick non-woven fabrics, laminating non-woven fabrics and non-woven fabrics. Non-woven products such as woven fabric, hot-rolled non-woven fabric, polypropylene non-woven fabric, spunlace non-woven fabric, etc., the non-woven products produced by our company are more and more popular in the market and are exported to China.
