Spunlaced non woven fabric is a kind of non woven fabric with special properties, which is composed of two or more fiber webs, wood pulp paper and non woven fabrics with different properties through spunlaced entanglement. This paper briefly introduces the performance characteristics and application fields of three-layer spunlaced laminated non woven fabric.

1."Sandwich" structure spunlaced laminated non woven

In the "sandwich" structure spunlaced laminated non woven market, the most common is the spunbonded non woven fabric sandwiched in the middle of the two-layer combed web. After spunlaced composite, the product has strong vertical and horizontal strength, good moisture absorption performance, rich hand feel, and greatly improves the user experience of consumers. This product is deeply loved by consumers as a wet towel and a dry towel.

In addition, wood pulp paper can also be used in the middle layer. Chen Han of Donghua University has studied the spunlaced laminated non woven (CPC). The research shows that in the selection of wood pulp paper, wood pulp wrinkled facial tissue paper has the characteristics of low tensile strength, good water absorption, flat cross-section, easy to ease under the action of spunlaced needle, and entangled with short fibers; The best mass percentage of wood pulp paper in CPC is 20% - 30%; At the same time, driven by the water needle, the wood pulp fiber can reach the CPC surface, making the product feel soft and plump, with high absorption, which is very suitable for wiping materials.

In addition, there is a "sandwich" structure: the upper and lower layers still use combed fiber nets, and the middle layer uses air flow mesh fiber nets. Air flow netting makes the fiber orientation of the middle layer uniform and fluffy. After spunlaced compounding, the product feels fluffy and softer, and is widely used in high-end wet and dry wipes for infants and young children. At the same time, the excess trimming part of the non woven fabric roll can be recycled and reused by the method of air forming mesh after crushing, which can effectively reduce the cost and improve the market competitiveness.

2.Other three-layer structure spunlaced laminated non woven

According to the registration of Dalian scientific and technological achievements in 2008, Dalian Ruiguang nonwovens Group Co., Ltd. developed SPC spunlaced non woven. This product is also a three-layer structure of spunbonded composite products. Spunbonded nonwovens are used as the bottom layer of the three-layer structure. The middle layer adopts the wood pulp fiber web formed by airflow, and the upper layer adopts the fiber layer formed by combing. Then the three layers of materials are superimposed together, and the fiber web is reinforced many times by spunbonded 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 spunlaced nonwovens, improve the comprehensive properties of spunlaced nonwovens and endow them with new functions, spunlaced non woven appeared. Understanding the relevant knowledge of three-layer structure spunlaced laminated non woven fabric is conducive to people's further understanding of spunlaced fabric.
