Tensile strength of plain spunlace nonwovens: the perfect fusion of fiber, interweaving and spunlace technology


In the world of textiles, tensile strength is one of the important indicators of the quality of a material. For non-woven fabrics, especially plain spunlace non-woven fabrics, tensile strength is not only related to the service life of the product, but also a decisive factor in its application field. This article will delve into the tensile strength of plain spunlace non-woven fabrics and the three major factors that affect its strength: the material of the fibers, the density of interweaving between fibers, and the processing method of the spunlace process.

The material of the fiber is the cornerstone that determines the tensile strength of non-woven fabrics. High-quality fiber materials, such as polypropylene (PP) and polyester (PET), have become the first choice for manufacturing plain weave spunlace non-woven fabrics due to their excellent physical properties and chemical stability. These materials have the characteristics of high strength, wear resistance, corrosion resistance, etc., so that the non-woven fabrics can maintain good stability when stretched and are not easy to deform or break.

The interweaving density between fibers is also an important factor affecting the tensile strength of non-woven fabrics. The greater the interweaving density, the stronger the mutual support between fibers, and the higher the tensile strength of the non-woven fabric. Therefore, during the production process, the tensile strength of non-woven fabrics can be effectively improved by controlling the arrangement and interweaving density of fibers.

The processing method of spunlace process plays a vital role in the tensile strength of non-woven fabrics. The spunlace process is a technology that entangles fiber layers with each other through high-pressure water flow. It can tightly combine loose fiber layers to form a dense and strong non-woven fabric. This process can not only increase the tensile strength of non-woven fabrics, but also improve its air permeability and water absorption.

The tensile strength of plain spunlace non-woven fabric is the result of the combination of fiber material, interweaving density and spunlace process. High-quality fiber materials and tightly interwoven structures provide a solid foundation for non-woven fabrics, while the spunlace process tightly binds fiber layers together through high-pressure water flow, further enhancing the tensile properties of non-woven fabrics. This perfect fusion makes plain spunlace nonwovens widely used in medical, health, home and other fields, and has won market recognition for its excellent performance and reliability.
