Application of wood pulp composite spunlace non-woven fabric in medical field

Non-woven material is a new type of flexible material formed by processing high molecular polymers, fibrous aggregates, etc. through physical or chemical methods. It combines the advantages of the four flexible materials of textile, paper, plastic and leather. Spunlace nonwoven material is one of the nonwoven materials with high technical content and good product style, and is highly praised by consumers. It has a development history of more than 20 years in my country, ranging from ordinary nonwoven materials to various functional nonwovens. Materials have been developed and applied to a certain degree. The spunlace composite technology is a major innovation to the traditional spunlace technology. The spunlace composite technology enriches the performance and functions of spunlace products through the crossover, penetration and fusion of multiple technologies, and greatly expands the application fields of spunlace products.


Wood pulp composite spunlace nonwoven material is a nonwoven composite material that uses spunlace technology to combine wood pulp fibers and synthetic fiber nets to form a structure of two kinds of fibers entangled with each other. This kind of material has good wear properties such as high strength and stretchability, good hand feeling, breathability and moisture permeability, and is widely used in the medical field based on the advantages of spunlace non-woven fabrics.


In 2003, my country was facing the threat of 'SARS'. There was a large demand for medical protective clothing with the function of isolating bacteria or viruses in the market. However, at that time, domestic medical protective clothing could not be produced in compliance with the requirements, resulting in medical protective clothing. A large number of imports, but disposable protective clothing that isolates bacteria and viruses is widely popular. The country has also issued the corresponding protective clothing standard GB19082-2003. Although the softness and air permeability of spunlace non-woven fabrics are very good, the two indexes of synthetic blood penetration and filtration efficiency are not up to standard if they are used to make protective clothing. Therefore, in addition to adding fine denier fibers to the raw materials, other processing techniques must be combined to completely solve the two problems of synthetic blood penetration and filtration efficiency.


Water-proof and flame-retardant multifunctional finishing of spunlace non-woven fabrics, giving the spunlace non-woven fabrics waterproof and flame-retardant effects;


The spunlace non-woven fabric is coated with composite processing to improve the filtration efficiency of the spunlace non-woven fabric.


After finishing the 'three-proof (waterproof, alcohol-proof, blood-proof)The process method of using wood pulp paper and polyester fiber net for spunlace composite reinforcement is simpler and lower in cost than the method of using wood pulp fiber air-laid and polyester fiber net spunlace composite. Most domestic enterprises use this method to produce wood pulp composite Spunlace material.


In addition, the commonly used surgical drapes, surgical gowns, etc. are also composited with non-woven fabrics and polyethylene (PE) membranes. The products do not shed hair, dyes and does not fade, and have good air permeability. Its craftsmanship and protection The services are basically the same, but the relevant standards will be different.
