Application and characteristics of automatic non-woven bag-making machine

1. Non-woven bags are widely used in clothing bags, information bags, shoe bags, shopping bags, advertising bags and so on. The production of non-woven bags has a good market prospect and great potential.

2. Automatic non-woven bag-making machine, with advanced design technology, fast production speed and high efficiency, can process environmental-friendly non-woven bags with different specifications and shapes, and has the characteristics of good quality and high bonding strength.

3. The weight is about 2 tons

4. This machine can make vest bag, handbag, flat pocket, side insert bag and bottom insert bag, which is stable and efficient.

5. Five sets of ultrasonic systems

6. vest bag: the length is 50-60cm, and the maximum length can be set to 80cm. Flat bag: 30 cm wide, 70-80 pieces/minute; 50 cm wide, 50-60 pieces/minute.

Generally, 70g non-woven fabric is used as the bag.

Main technical parameters of automatic non-woven bag-making machine: model Gy-600/900/1200/1400, production speed 10-70 PCs/min, installed power of 28 kw, total weight 1 T, overall dimensions (length× width)

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

The 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, wrapping 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 Non-woven fabrics break through the traditional textile principles, and have the characteristics of short technological process, fast production speed, high output, low cost, wide use and many sources of raw materials.
