What Is Spunlace Nonwoven Fabric
Do you know what spunlace nonwoven fabric is? Spunlace nonwoven fabric is one of many nonwoven fabrics. Everyone may feel unfamiliar to hear the name, but in fact, we often use spunlace nonwoven products in our daily life, such as wet towels, cleaning wipes, disposable face towels, facial mask paper, etc. This article I will introduce spunlace nonwoven fabrics in detail .
1.The Process Of Spunlaced Nonwoven Fabric
Nonwoven fabric is a kind of fabric that does not need to be woven. It just arranges polypropylene, polyester and other fiber materials directed or randomly to form a fiber net structure, and then uses mechanical，chemical or thermal bonding methods to reinforce them. Simply speaking, it is the bonding of fibers directly together, but it’s not interwoven and knit together by yarns. Therefore, when we get the nonwoven fabric, we will find that it has no warp and weft threads, and the thread residues can not be drawn out. It is easier to cut, sew and shape. Nonwoven fabric has the characteristics of short process flow, wide source of raw materials, fast production rate, low cost, high output, multiple product types, and wide application. It can also be made into cloths with different thickness, hand feeling and hardness according to requirements. Nonwoven fabric not only breaks through the traditional textile principle, but also provides a lot of convenience for our lives.
Nonwoven fabric can be divided into wet process nonwoven fabric and dry process nonwoven fabric according to the manufacturing process. The wet profess refers to the final formation of nonwoven fabric is in water. The process is usually used in papermaking. The dry profess refers to the final formation of nonwoven fabric is in the air,which including heat seal ( meltblown, spunbond, thermal bonding ), needle-punching, spunlace, chemical bonding, stichbond, etc.
Among them, spunlace nonwoven fabric refers to a nonwoven fabric made with spunlace process, and the water thorn machine produces a high-pressure water needle (using high-pressure multi-strand fine water jet) to jet the web. After the high-pressure water needle passes through the web, shoot it onto the contained metal mesh conveyor belt, and as the mesh enclosure bounces,the water spatters through it again, which continuously puncture, spread, and use hydraulic to make fibers generate displacement, inserted, entangled, and huddle, thereby reinforcing the web to form a strong, uniform spunlace thin fiber web. The resulting fabric is the spunlace nonwoven fabric.
Nowadays, as the technology continues to mature, new products are constantly emerging, and the market application areas continue to expand, showing its broad development prospects.
2.Spunlace Nonwoven Production Line
The production process of the Spunlace nonwoven fabric is : Feeding Cotton → Opening→ Carding→Lapping→Spunlace→ Drying→ Winding
Feeding cotton: put different ratio of fiber raw materials into equipment.
Opening: High-power blower blows the fiber raw materials to disperse the large fiber block, the fiber group, and make it fluffy.
Carding: The prepared fibers are combed into thin webs of single fiber to ready for lapping.
Lapping: The thin web reciprocates on a web curtain, and the web is laid in an orderly manner. Spunlace nonwoven fabric has three lapping ways: parallel lapping, cross lapping and random lapping.
Spunlace: high-pressure water needles make orderly fibers generate displacement, inserted, entangled, and huddle.
Drying: Remove water and volatile substances of the cloth, dry the wet surface.
Winding: Wind the finished nonwoven fabrics into rolls.
3.The Composition Of Spunlace Nonwoven Fabric
Spunlace nonwoven fabric has a wide range of fiber raw materials, which can be polyester, nylon, polypropylene, viscose fiber, chitin fiber, superfine fiber, lyocell, silk, bamboo fiber, woodpulp fiber, seaweed fiber, etc. At present, the four most widely used materials in the market are viscose fiber, woodpulp fiber, polyester and polypropylene.
Viscose fiber is a kind of cellulose fiber, using "wood" as the raw material, extracting and reshaping the fiber molecules from natural wood cellulose to obtain cellulose fiber. In detail, viscose is made of natural fiber (wood fiber, cotton linters) as raw materials, and is made by soluble cellulose xanthate through alkalization, aging, sulfonation and other processes, and then dissolved in dilute lye and subjected to wet method spinning to make viscose.
Viscose fiber has good water absorption, and meets the needs of human skin with the characteristics of refreshing, breathable, anti-static, anti-ultraviolet, good dyeing fastness, and biodegradability. It not only has the essence of cotton but also the quality of silk, which is originate from nature and superior to nature. At present, viscose is widely used in various nonwoven fields such as wet wipes, face towels, and rags.
Woodpulp fiber is a kind of fiber made of woodpulp as raw material, but it is different from ordinary plant fiber. It is a secondary fiber, it is a product separated from the original wood fiber, and it is mostly used in the textile field. Because it is mainly extracted from woodpulp, we call it woodpulp fiber, which is similar to paper pulp.Wood pulp fiber has high liquid absorption and it is biodegradable.
Polyester was invented in 1941. It is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and glycol, referred to as PET fiber. It is a polymer compound and is currently the largest variety of synthetic fibers. It has high strength and elastic recovery ability, good wrinkle resistance and shape retention, at the same time it has good heat resistance, water absorption and oil absorption, strong and durable. Due to its characteristics, polyester is widely used in textile and nonwoven fields, mainly used as raw materials of wet wipes, cleaning wipes, and clothing.
Polypropylene refers to synthetic fiber named isotactic polypropylene fiber made from propylene, a by-product of petroleum refining, non-biodegradable. It has light weight but high strength, excellent wear resistance and elastic recovery, chemical resistance is better than most fibers, and has anti-bacterial, safe and sanitary characteristics. Not only that, polypropylene is resistant to oil stains, easy to wash and dry, it is widely used in the field of oily cleaning wipes.
4.Product Classification Of Spunlace Nonwoven Fabrics
Based on years of market development and comprehensive application feedback in various fields, currently the most used spunlace nonwovens on the market can be divided into four categories: spunlace viscose & PET nonwoven fabric, spunlace woodpulp & PET nonwoven fabric, spunlace woodpulp & PP nonwoven fabric and biodegradable material. The four types of spunlace nonwoven materials are widely used in industrial wipes, civil wipes, medical materials, beauty nonwoven materials and other fields.
