Do you know what wet tissues or masks are made from?
when you look closely at the surface of a wet tissue or mask, you can see that the fibers are not well woven but tangled. The reason for this is because it is made using spunlace non-woven fabric.
Then what is spunlace nonwoven?
In this post, we will learn about spunlace nonwoven fabric.
Main features of spunlace nonwoven fabric
Physical bonding process : Spunlace nonwovens are bonded using high-pressure water jets so that the fibers are intertwined irregularly. It is also used in products where durability is important, as the product is very soft, flexible, and maintains firmness even when wet.
Skin-friendly : Since spunlace non-woven fabric does not use adhesives, it does not irritate the skin and is often used in products such as wet wipes, diapers, and beauty care. It also has a very soft and flexible texture, making it comfortable against the skin.
Can be mixed with a variety of fibers : Spunlace nonwovens can be mixed with natural and synthetic fibers, allowing products to be designed for specific applications. A variety of processing, including pattern design, thickness control, and post-processing, is possible, allowing customization for each application.
Manufacturing process of spunlace nonwoven fabric
Preparation of raw materials : Spunlace nonwoven fabrics mainly use fibers such as cotton, polyester, nylon, and rayon as raw materials. These raw materials are prepared in the form of fabrics, and different types of fibers can also be mixed.
Fiber separation and placement : Raw fibers are separated or processed into very thin fibers and placed randomly. At this time, the fibers are not arranged in a certain direction but are distributed randomly.
Water jet treatment : The key process for spunlace nonwovens is water jet (spunlace). This method uses high-pressure water to weave fibers together. High-pressure water is sprayed on the fibers to physically weave them together, and at this time, the fibers are strongly bonded to form a single non-woven fabric.
Water jetting is a technique that sprays very fine water droplets at high speed to entangle fibers together. This method is environmentally friendly because it does not use chemicals, and maintains the soft, natural texture of the non-woven fabric.
Drying and post-processing : After the water jet treatment, the non-woven fabric goes through a drying process. Afterwards, additional post-processing processes such as dyeing, printing, and coating may be performed as needed.
Final product inspection : Once the nonwoven fabric is completed, it goes through quality inspection to filter out defective products, and is finally cut or processed into a shape that meets the customer's needs before being shipped.
Uses of spunlace nonwoven fabric
Hygiene products: wet tissues, toilet paper, cleaning tissues, etc.
Medical supplies: dressings, bandages, medical filters, etc.
Industrial filter: used as a material for filtering air or liquid
Cleaning supplies: various cleaning cloths, mops, etc.
Spunlace nonwoven fabric is a nonwoven fabric made by weaving fibers together through a water jet, a physical bonding process, and is characterized by soft and flexible characteristics. Because of this, it is useful in various fields such as medicine, hygiene, and filters.
