What is the difference between spunlace and spunbond fabric?
Hello everyone, today I'm going to introduce two types of nonwoven fabrics: spunlace fabric and spunbond fabric. These two products are manufactured by our company, Husheng Nonwovens, and we ship thousands of tons of them worldwide every year. So what are the differences between these two fabrics?
What is spunlace fabric?
Spunlace fabric is a type of nonwoven fabric produced using a hydroentanglement process. It is made by interlocking fibers together with high-pressure water jets. The manufacturing process involves several steps, including pre-treatment, web formation, hydroentanglement, cleaning, and finishing.
Manufacturing process of spunbond fabric:
Spunbond fabric is produced by extruding melted polymer fibers into continuous filaments, which are then solidified through cooling to form a nonwoven fabric. The production process includes fiber extrusion, web formation, thermal stretching, and cooling. Compared to spunlace fabric, the manufacturing process of spunbond fabric is more complex and requires advanced equipment.
Differences in physical properties:
There are significant differences between spunlace fabric and spunbond fabric. In terms of fiber structure, spunlace fabric has a looser structure, resulting in relatively lower filtration efficiency. On the other hand, spunbond fabric has a denser fiber structure, providing excellent filtration efficiency, especially for filtering viruses. That's why it is commonly used in the production of face masks. Spunlace fabric is known for its softness, good moisture absorption, and breathability, while spunbond fabric offers high strength, good abrasion resistance, and superior tensile properties. They also differ in other aspects.
Moisture absorption capacity:
Spunlace fabric exhibits excellent water absorption properties, making it an ideal material for wet wipes, facial cleansing wipes, and medical dressings. In comparison, spunbond fabric has lower liquid absorbency but is suitable for applications requiring higher mechanical strength and protective performance, such as medical masks, KN95 masks, and N95 respirators.
Applications of spunlace fabric:
Spunlace fabric is commonly used in areas that demand softness, high water absorption, and drainage capabilities. Its applications include baby products, cleaning products, and other fields where sufficient softness is required, like cleansing wipes.
Applications of spunbond fabric:
Spunbond fabric finds its main application in the medical industry, particularly in the production of disposable masks, isolation gowns, and medical dressings. It has been widely adopted worldwide for these purposes.
Although the manufacturing processes of spunlace fabric and spunbond fabric are somewhat similar, spunlace fabric has a simpler production process compared to spunbond fabric, resulting in lower costs. Spunbond fabric, with its more complex production process, tends to have higher manufacturing costs.
I have discussed the differences between spunlace fabric and spunbond fabric in various aspects, with emphasis on their softness and moisture absorption properties. When selecting materials, it is important to consider the specific requirements and application scenarios. Choosing the right nonwoven fabric will contribute to delivering better end products that meet market demands.
