Meet The Three-layer Structure Spunlace Non Woven Fabric

Spunlace non woven fabric is a non woven fabric with special properties formed by spunlace entanglement of two or more types of fiber webs, wood pulp paper, non-woven fabrics, etc. with different properties. This paper briefly introduces the performance characteristics and application fields of the three-layer structure Spunlace non woven fabric.

1. "Sandwich" structure Spunlace non woven fabric

The "sandwich" structure Spunlace non woven fabric is the most common in the market. Two layers of carded fiber webs are sandwiched with spunbond non-woven fabrics. After spunlace lamination, the product has strong vertical and horizontal strength and good Moisture absorption performance, feel full, greatly enhance the consumer experience. The product is favored by consumers as wet wipes and dry wipes.

In addition, wood pulp paper can also be used for the intermediate layer. Chen Han from Donghua University conducted research on carded-wood pulp paper-carded-to-net (CPC) spunlace composite non-woven fabrics. The research shows that, in the selection of wood pulp paper, the tensile strength of wood pulp crepe tissue paper is low. , good water absorption, flat cross section, easy to dissolve and entangle with short fibers under the action of spunlace needle; the best mass percentage of wood pulp paper in CPC is 20% to 30%; at the same time, driven by water needle , The wood pulp fiber can reach the surface of CPC, making the product feel soft and plump, with high absorbency, which is very suitable for wiping materials.

In addition, there is a "sandwich" structure: the upper and lower layers still use a carded fiber web, and the middle layer is an air-laid fiber web. Airlaid makes the fiber orientation of the middle layer uniform and fluffy. The spunlace composite product feels more fluffy, more skin-friendly and soft, and is widely used in high-end infant wipes and dry wipes. At the same time, the excess trimmed portion of the non-woven roll can be pulverized and recycled by air-laid, which can effectively reduce costs and enhance market competitiveness.

2. Other three-layer structure Spunlace non woven fabric

According to the registration of scientific and technological achievements in Dalian in 2008, Dalian Ruiguang Nonwovens Group Co., Ltd. developed SPCSpunlace non woven fabric. This product is also a Spunlace non woven fabric with a three-layer structure, that is, the spunbond non-woven fabric is used as the bottom layer in the three-layer composite product, the air-laid wood pulp fiber web is used as the middle layer, and the carded fiber layer is used as the upper layer. Then the three layers of materials are superimposed together, and the fiber web is reinforced several times by spunlace technology. The products are mainly used in the fields of sanitary materials, industrial materials and medical supplies.

In order to expand the application field of Spunlace non woven fabric, improve the comprehensive performance of spunlace nonwoven fabric, and give it new functions, Spunlace non woven fabric came out. Knowing about the three-layer structure Spunlace non woven fabric will help people to further understand this material.
