Concept of Hydroentangled Nonwoven Fabrics: Hydroentangled Nonwoven Fabrics, also known as hydroentangled nonwoven fabrics, is also known as "Jet Spraying Fabrics".
The concept of "jet spraying fabric" comes from the mechanical needling process. The so-called "jet spraying" is the use of high-pressure water jet into the fiber network, so that the fibers are intertwined, so that the original loose fiber network has a certain strength and complete structure.
The process is: fiber metering and mixing-opening and debris removal-mechanical mess combing into the network-fiber network pre-wetting-water-needle intertwining-surface treatment-drying -Rolling - Inspection - Packaging and storage. Jet spraying device is the use of high-speed flow of high-pressure water jet fiber network, so that the fibers in the fiber network rearrangement, entangled with each other, into a structural integrity, with a certain degree of strength and other properties of the nonwoven fabric.
The physical properties of this hydroentangled nonwoven fabric are different from those of the common needle-punched nonwoven fabrics, both in terms of feel and performance, which are the only nonwoven fabrics that can make their final products similar to textiles. Advantages of the spunlace method: the spunlace process does not exist in the fiber network of extrusion, thus improving the final product of the puffiness; does not use resins or adhesives, thus maintaining the inherent softness of the fiber network; the high degree of integrity of the product to avoid fluffy phenomena; fiber network has a high mechanical strength, up to 80% to 90% of the strength of the textile; the network can be used in any variety of fibers blended together.
Specially worth mentioning is that the spunlace fiber mesh can be compounded with any base cloth to make composite products. According to different uses to produce a variety of functional products.
Advantages of Hydroentangled Fabric: 1, soft, good drape; 2, good strength; 3, with high moisture absorption and quick wetting; 4, low linting; 5, washable; 6, no chemical additives; 7, similar to the appearance of textiles. Outlook for Hydroentangled Fabrics: Due to the advantages of hydroentangled fabrics, it has become one of the fastest technological advances in the non-manufacturing community in recent years.
The direction of development of non-woven fabrics is to replace textile and knitted products, spunlace fabrics with its most like the characteristics of textiles, excellent physical properties, the advantages of good value for money to become the most promising areas of competition with the textile market. Hydroentangled cloth applications: First, medical use with abandoned surgical gowns, surgical coveralls, surgical table cloths, surgical aprons, etc.; wound dressings, bandages, gauze, band-aids, etc.; Second, clothing such as clothing interlining, baby clothes, training clothes, carnival night disposable color clothing, all kinds of protective clothing such as surgical suits, etc.; Third, wipes such as household, personal, beauty, industrial, medical wipes, etc.; Fourth, decorative fabrics such as automotive interiors, home interiors, stage decorations, such as the car, the car, the car, the car, the car, the car. Decorative fabrics such as car interiors, home interiors, stage decorations, etc.; v. Agricultural categories such as heat preservation greenhouses, anti-weed growth, harvest cloth, insect-resistant preservation cloth, etc.; vi. Spunlace nonwoven fabrics can be used for composite processing, you can produce "sandwiches" type of structure of the product, the development of a variety of uses of the new composite materials.
And PE is the abbreviation for polyethylene.
What is the difference between nonwoven fabrics, needle-punched nonwoven fabrics, water-pricked nonwoven fabrics and so on
First, the production method is different
1, nonwoven fabrics: nonwoven fabrics, also known as non-woven fabrics, is composed of oriented or random fibers.
2, needle-punched nonwoven: needle-punched nonwoven belongs to a kind of nonwoven, polyester, polypropylene raw material manufacturing, after a number of times needling to appropriate hot-rolled treatment and become.
3, spunlace nonwoven fabrics: spunlace nonwoven fabrics is a high-pressure micro-fine water jet to one or more layers of fibers on the fiber network, the fibers are entangled with each other, so that the fiber network can be reinforced with a certain strength, the fabric obtained that is spunlace nonwoven fabrics.
Second, the application of different
1, non-woven fabrics: for agricultural film, shoes, tanning, mattresses, mother and child quilt, decorative, chemical, printing, automotive, building materials, furniture and other industries, and apparel lining, medical disposable surgical gowns, masks, hats, bed linen, hotels, disposable tablecloths, cosmetology, sauna and even today's fashionable gift bags, boutique bags, shopping bags, advertising bags and so on. Environmental protection products, widely used, economical. Environmental protection products, wide range of uses, affordable. Because of its appearance resembles a pearl, also known as pearl canvas.
2, needle punched nonwoven fabric: according to different processes, with different materials, made of hundreds of commodities, all walks of life are used, can be customized according to different uses of various specifications.
3, spunlace nonwoven fabrics: spunlace nonwoven fabrics are used for medical curtains, surgical gowns, surgical cover cloths, medical dressings, wound dressings, medical gauze, aviation rags, clothing lining base cloth, coating base cloth, with that is to be disposed of materials, instrumentation, high-level rags, electronic industry, high-level rags, towels, cotton pads, wet wipes, masks, wrapping materials and so on.
Third, the characteristics of different
1, non-woven: non-woven products are colorful, bright, fashionable and environmentally friendly, versatile, beautiful and generous, patterns and styles are diverse, and lightweight, environmentally friendly, recyclable, internationally recognized as the protection of the earth's ecological products.
2, needle-punched nonwoven fabric: the fiber is thicker, the feel is rougher, the surface has tiny pinholes.
3, hydroentangled nonwoven fabrics: soft hand, fluffy, high moisture absorption, a certain degree of oil absorption; flexible entanglement, does not affect the original characteristics of the fibers, does not damage the fibers; high strength, low linting; high hygroscopicity, rapid moisture absorption; soft hand, good drape.

Nonwoven fabrics Wood Pulp Composite Nonwoven Fabrics Thermal Taping Nonwoven Fabrics Hydroentangled Nonwoven Fabrics Difference Uses? Nonwoven fabrics can be divided into:
1, hydroentanglement nonwoven fabrics: is a high-pressure micro-fine water jet to a layer or layers of fibers on the fiber network, the fibers are entangled with each other, so that the fiber network can be reinforced with a certain strength.
2, thermal bonding nonwoven fabrics: refers to the fiber network to join the fiber or powder hot melt bonding reinforcing materials, fiber network and then heated and melted and cooled into a cloth reinforcement.
3, pulp airflow into the net nonwoven: also known as dustless paper, dry paper nonwoven. It is the use of airflow into the network technology will be wood pulp fiber board open into a single fiber state, and then use the airflow method to make the fiber coagulation in the net curtain, the fiber network and then reinforced into the cloth.
4, wet nonwoven: is placed in aqueous media fiber raw materials open into single fiber, while making different fiber raw materials mixed, made of fiber suspension slurry, suspension slurry transported to the netting mechanism, the fiber in the wet state into the net and then reinforced into cloth.

Characteristics of nonwoven fabrics
-Nonwoven fabrics break through the traditional textile principles, and has a short process, fast production speed, high yield, low cost, wide range of uses, raw materials from many sources.
What is the difference between hydroentangled nonwoven fabrics and needle punched nonwoven fabrics
Needle punched nonwoven fabrics Needle punched nonwoven fabrics is a kind of dry nonwoven fabrics, needle punched nonwoven fabrics is the use of felting needles puncture, the fluffy fiber mesh reinforcing the cloth.
Needle-punched nonwoven fabrics, hydroentangled nonwoven fabrics belong to nonwoven fabrics (also known as nonwovens), is a nonwoven fabric in the dry/mechanical reinforcement of two of them.
As the name suggests, the biggest difference between the two processes is the reinforcement of a mechanical needle reinforcement of a mechanical high-pressure water-needle reinforcement, the different process directly to the finished product function of different applications.
Needle nonwoven production weight is generally higher than the weight of the spunlace nonwoven. Hydroentangled nonwoven raw materials are more expensive, the fabric is more delicate, the production process is cleaner than needle punching. Health medical/hygiene/beauty is more widely used. Needle-punched raw materials than a wide range of water-pricked, many varieties, filter material * / felt / geotextile and so on.
