spunlace nonwoven

Knowledge of spunlaced nonwovens-spunlaced nonwovens I want to know the specific aspects of spunlaced nonwovens.

The concept of spunlaced nonwovens: spunlaced nonwovens, also known as spunlaced nonwovens, also known as spunlaced nonwovens.

The concept of "spraying net into cloth" comes from mechanical needling process. The so-called "jet-spraying net" is to puncture the fiber net with high-pressure water, so that the fibers are intertwined and the original loose fiber net has a certain strength and complete structure.

The process flow is as follows: fiber metering and mixing, opening and impurity removal, mechanical carding and web forming, fiber web pre-wetting, water needle winding, surface treatment, drying, coiling, inspection, packaging and warehousing. The jet-mesh-spraying device uses high-speed and high-pressure water to spray the mesh, so that the fibers in the mesh are rearranged and interwoven to become a non-woven fabric with complete structure and certain strength.

The physical properties of this spunlaced nonwovens are different from those of common needle-punched nonwovens, and it is the only nonwovens that can make its final product similar to textiles in hand feel and performance. Advantages of spunlace method: there is no extrusion of fiber web during spunlace process, thus improving the bulkiness of the final product; No resin or adhesive is used, so the inherent softness of the net is maintained; The high integrity of the product avoids the fluffy phenomenon of the product; The mechanical strength of the web is high, which can reach 80% ~ 90% of the textile strength; The web can be mixed with any kind of fibers.

It is particularly worth mentioning that spunlace net can be compounded with any base fabric to make composite products. Products with various functions can be produced according to different uses.

Advantages of spunlaced cloth: 1, soft and good drape; 2. Good strength; 3. It has high hygroscopicity and rapid humidity; 4. Low fuzziness; 5, washable; 6. No chemical additives; 7, the appearance is similar to textiles. Prospect of spunlaced fabric: Due to its advantages, spunlaced fabric has become the fastest-growing field of non-manufacturing technology in recent years.

The development direction of nonwovens is to replace textiles and knitwear, and spunlace has become the most potential field to compete with the textile market because of its most textile-like characteristics, excellent physical properties and low price. Application of spunlaced cloth: 1. Disposable surgical gown, surgical drape, surgical tablecloth, surgical apron, etc. Medical use; Wound dressing, bandage, gauze, band-aid etc. ; Second, clothing interlining, baby clothes, training clothes, carnival night disposable colorful clothes and other clothing, as well as surgical clothes and other protective clothing; 3. Wet wipes such as household, personal, beauty, industrial and medical dry wipes; Fourth, decorative fabrics such as automobile interiors, family interiors, stage decorations, etc. ; 5. Agricultural products such as heat preservation greenhouse, weed prevention, harvesting cloth, insect-proof and fresh-keeping cloth. 6. Spunlaced nonwovens can also be used for composite processing, producing sandwich products and developing new composite materials with multiple uses.

PE is short for polyethylene.

What's the difference between nonwoven fabric, needle-punched nonwoven fabric and spunlaced nonwoven fabric?

First, the production methods are different.

1. Nonwovens: Nonwovens, also called nonwovens, are composed of oriented or random fibers.

2. Needle-punched nonwovens: Needle-punched nonwovens are a kind of nonwovens, which are made of polyester and polypropylene by repeated needling and proper hot rolling.

3. Spunlaced nonwovens: Spunlaced nonwovens are made by spraying high-pressure micro-water on one or more layers of fiber webs to interweave the fibers, so that the fiber webs are strengthened and have certain strength, and the obtained fabrics are spunlaced nonwovens.

Second, the application is different.

1, non-woven fabrics: suitable for agricultural film, shoemaking, tanning, mattress, quilt, decoration, chemical industry, printing, automobile, building materials, furniture and other industries, as well as clothing interlining, disposable surgical gown for medical and health care, masks, hats, bed sheets, disposable tablecloths in hotels, beauty salons, saunas and even fashionable gift bags, boutique bags, shopping bags and advertising bags. Environmental protection products are widely used and economical. Because it looks like a pearl, it is also called a pearl canvas.

2. Needle-punched non-woven fabrics: hundreds of kinds of goods are made according to different technologies and materials, which can be used in all walks of life, and products of various specifications can be customized according to different purposes.

3. Spunlaced nonwovens: Spunlaced nonwovens are used as coating materials for medical curtains, surgical gowns, surgical covers, medical dressings, wound dressings, medical gauze, aviation rags, garment lining base cloth, coating base cloth, disposable materials, advanced rags for instruments and meters, advanced rags for electronic industry, towels, cotton pads, wet wipes and masks.

Third, the characteristics are different.

1, non-woven fabric: non-woven fabric products are rich in color, bright, fashionable and environmentally friendly, widely used, elegant in appearance, diverse in patterns and styles, light in weight, environmentally friendly and recyclable, and are internationally recognized as environmentally friendly products for protecting the earth's ecology.

2. Needle-punched non-woven fabric: the fiber is thick, the hand feels rough, and there are fine pinholes on the surface.

3. Spunlaced non-woven fabric: soft, fluffy, hygroscopic, and has a certain oil absorption effect; Flexible entanglement does not affect the original characteristics of the fiber and does not damage the fiber; High intensity and low ambiguity; High hygroscopicity and rapid hygroscopicity; Soft feel and good drape.

Application of Spunlaced Nonwovens

What are the different uses of nonwoven wood pulp composite nonwoven hot-rolled nonwoven spunlaced nonwoven? Non-woven fabrics can be divided into:

1, spunlaced nonwovens: high-pressure micro-water is sprayed on one or more layers of fiber webs to interweave the fibers, so that the fiber webs are strengthened and have certain strength.

2. Hot-bonded nonwoven fabric: refers to adding fibrous or powdery hot-melt bonding reinforcing materials to the fiber web, and then heating, melting and cooling the fiber web to strengthen it into cloth.

3. Pulp airlaid nonwovens: It can also be called dust-free paper and dry-made nonwovens. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to bond the fibers to the net curtain, and the fiber net is reinforced into cloth.

4. Wet nonwovens: fiber raw materials placed in water medium are opened into single fibers, and at the same time, different fiber raw materials are mixed to make fiber suspension slurry, which is conveyed to the web-forming mechanism to form a web in a wet state, and then reinforced into cloth.

5. Spunbonded nonwovens: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a net, and the net is transformed into nonwovens through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement.

6. Melt-blown nonwovens: Its technological process: polymer feeding-melt extrusion-fiber forming-fiber cooling-web forming-enhanced cloth forming.

7. Needle punched nonwovens: It is a kind of dry nonwovens. Needle-punched nonwovens use the puncture effect of needles to strengthen fluffy fiber webs into cloth.

8. Stitched non-woven fabric: It is a dry non-woven fabric. The sewing method is to reinforce the net, yarn layer and non-woven materials (such as plastic sheets and plastic foils). ) or a combination thereof, by using a warp knitting loop structure.

Use of non-woven fabrics

Its main uses can be roughly divided into:

(1) Non-woven fabrics for medical and health care: surgical gowns, protective clothing, disinfection kits, masks, diapers, household rags, rags, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary napkins;

(2) Non-woven fabrics for home decoration: wall covering, tablecloths, sheets, bedspreads, etc. ;

(3) Non-woven fabrics for clothing: lining, adhesive lining, wadding, setting cotton, various synthetic leather base fabrics, etc.

(4) industrial nonwovens; Filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc. ;

(5) Non-woven fabrics for agriculture: crop protection cloth, nursery cloth, irrigation cloth, thermal insulation curtain, etc.

(6) Other non-woven fabrics: space cotton, heat and sound insulation materials, oil-absorbing felt, cigarette filter tips, tea bags in bags, etc.

Characteristics of non-woven fabrics

Nonwovens break through the traditional textile principle and have the characteristics of short technological process, fast production speed, high output, low cost, wide application and many sources of raw materials.

What is the difference between spunlaced nonwovens and needled nonwovens?

Needle punched nonwovens needle punched nonwovens is a kind of dry spun nonwovens. Needle-punched non-woven fabric is to use the puncture effect of needles to strengthen fluffy fiber webs into fabrics.

Needle punched nonwovens and spunlaced nonwovens belong to nonwovens (also called nonwovens), which are dry/mechanical reinforcement in nonwovens.

As the name implies, the biggest difference between the two technologies is that the last one is mechanical needle reinforcement and the other is mechanical high-pressure water needle reinforcement. The difference of technology directly makes the functional application of its finished products different.

The gram weight of needle-punched nonwovens is usually higher than that of spunlaced nonwovens. The raw materials of spunlaced nonwovens are more expensive, the fabric surface is more delicate, and the production process is cleaner than needle punching. It is widely used for medical/sanitary/cosmetic purposes. Compared with spunlace, the raw materials of needling are more extensive and diverse, such as filter material */felt material/geotextile, etc.
