Non-woven cloth bag making machine

Principle and characteristics of nonwoven bag making machine

Non-woven bag making machine is from the feeder real-time feeding powder (colloid or liquid) to the top of the hopper machine, the introduction speed is controlled by the photoelectric positioning device, and the sealing paper (or other packaging material) is introduced into the lapel shaper by the Guide roller, which is folded and then lapped into a cylindrical shape by a longitudinal seal. The material is automatically measured and filled into the bag, the transverse sealer in the heat-sealing cutting at the same time the bag cylinder intermittently traction, finally forming lap joint longitudinal seam three sealing flat bag, complete a bag of sealing.

Second, Non-woven bag classification Non-woven bags by use Category: 1, advertising advertising bag shopping bag advertising can use the limited size of the bag, to the world to disseminate information on enterprise or product services.

If the shopping bag printed on the simple and elegant design and text, give a noble and solemn feeling, presumably also will cause some consumers shopping taste.

According to the different production process can be divided into:

1, Water thorn: is the high-pressure micro-flow spray to a layer or multi-layer fiber network, so that the fiber intertwined with each other, so that the fiber network to strengthen and have a certain strength.

2, heat-bonded non-woven bag: Refers to the fiber in the fiber-like or powder hot melt bonding reinforcement materials, fiber network and then through the heating and melting cooling to strengthen the cloth.

3, pulp flow into the net Non-woven bag: can also be called dust-free paper, dry paper non-woven fabric. It is the use of air flow into the network technology to open the wood pulp fiberboard into a single fiber state, and then use the Airflow method to make the fiber agglutination in the screen, fiber mesh reinforced into cloth.

4, wet-process Non-woven bag: is placed in the water medium of fiber raw materials into a single fiber, at the same time make different fiber raw materials mixed, made of fiber suspension slurry, suspended slurry into a network mechanism, fiber in the wet state into the network and then strengthened into cloth.

5, spunbonded Non-woven Bag: Is in the polymer has been extruded, stretching and forming a continuous filament, long wire laying into a network, fiber network and then through its own adhesion, thermal bonding, chemical bonding or mechanical reinforcement methods, so that the fiber mesh into non-woven fabric.

6, Melt Spray Non-woven Bag: The process: Polymer feeding-melt extrusion--fiber formation.

7, Acupuncture: is a dry non-woven fabric, needle-punched non-woven cloth is the use of needle puncture effect, will be a fluffy fiber mesh reinforcement into cloth.

8, seam: is a dry process non-woven fabric, sewing method is the use of warp knitting coil structure on the fiber network, yarn layer, non-woven materials (such as plastic sheeting, plastic thin metal foil, etc.) or their combination of reinforcement, in order to make non-woven fabric.

According to the use of different products can be divided into:

1, Non-woven Bag series: Non-woven non-woven bags, Non-woven bags, non-woven shopping bags.

2, Non-woven Bag Series: Non-woven file bags, environmental protection shopping bags, packaging bags, non-woven handbags.

Third, Non-woven bag production process non-woven bag is generally used screen printing technology, that is, people often say "screen printing", which has been a lot of manufacturers more commonly used printing technology. It's usually artificial, so the process of color control is not good control, so there are many new Non-woven printing methods, here we introduce the current market of several mainstream: But with the guests of the product of exquisite printing and environmental protection requirements continue to improve, emerging many new Non-woven printing methods, Here we introduce the current mainstream in the market several:

First, the watermark because of its use of water-based mortar as a printing medium and the name, in the textile printing is more common, also known as printing. When printing, the color paste and water-based elastic glue are reconciled. The developed version without chemical solvents, can be directly washed with water. It is characterized by good tinting strength, strong covering and fastness, washable, basically no odor.

Second, gravure printing by this method of finished products are usually called laminating non-woven bags. This process is divided into two steps, that is, the traditional gravure printing process will be printed to the film, and then the laminating process will be printed on the film composite on Non-woven fabric. General large-area color pattern printing non-woven bags are used in this process. It is characterized by exquisite printing, the whole process of machine production, short production cycle. In addition, the product has excellent waterproof performance, the durability of the finished product is better than other non-woven bags. The film has two kinds of light and matte to choose from, matte with sanding effect! The disadvantage is that there is conflict with the concept of environmental protection, because the film is difficult to degrade.

Third, thermal transfer printing in the printing of special printing! The method needs intermediate medium, that is, the graphic printing to the heat transfer film or heat transfer paper, and then through the transfer equipment heating to transfer the pattern to the non-woven fabric. The medium used in textile printing is the Heat transfer film. Its advantages are: beautifully printed, rich level version, comparable to photos. Suitable for small area color image printing. The disadvantage is that the price is high and the printing cost is higher.
