Technical route of modular non-woven fabric

The household cleaning wipes material technical route of module can obtain two-component spunbond nonwovens with no nip point and high air permeability; the twin-screw extrusion technology solves the problem of low melting point in large-scale and continuous production The problem of polymer drying. Non-woven fabrics have been granted 1 invention patent and 12 utility model patents. Non-woven fabrics have independent intellectual property rights. Non-woven fabrics are the first to realize the two-component spunbond non-woven filter framework material in China. Industrialization. After testing by the National Textile Machinery Quality Supervision and Inspection Center, the relevant indicators of the project meet the requirements of the mission statement.

The non-woven fabric and the product have been well received by users. The non-woven fabric has good economic and social benefits. Fiber chemistry The structure mainly refers to the binding performance of fiber molecules and water. The stronger the binding performance, the better the moisture absorption of the fiber, the stronger the fiber's ability to swell in water, the better the dispersion of the fiber. The surface state of the fiber mainly refers to the surface friction of the fiber Performance, the greater the friction coefficient of the fiber surface, the easier the fiber is entangled, and the more difficult it is to disperse in water. Appropriate surface treatment can be performed on the fiber, or a moisture absorbent, dispersant, etc. can be added to the slurry to improve the dispersion performance of the fiber.

Appropriate additives can be added to increase the viscosity of water, fix the fibers and prevent them from entanglement. Whether the fibers can be evenly dispersed and suspended in water also depends on the concentration of the fibers in the water. Obviously, the more difficult to disperse the fibers, the lower the concentration should be , The greater the water consumption. After testing, when forming a web, the allowable fiber pulp concentration and fiber length and fineness are as follows. Non-woven bag classification Non-woven bags can be divided into spunlace non-woven bags according to different production processes: It is to spray a high-pressure fine water stream onto one or more layers of fiber webs to make the fibers intertwined, so that the fiber web can be reinforced and have a certain strength.

Heat-sealing non-woven bag: refers to adding fibrous or Powdery hot-melt adhesive reinforcement material, the fiber web is heated, melted and cooled to reinforce into a cloth. Pulp air-laid non-woven bags can also be called dust-free paper, felt cloth dry paper-making non-woven fabrics. It uses airflow The web-forming technology opens the wood pulp fiberboard into a single fiber state, and then uses the airflow method to agglomerate the fibers on the web-forming curtain, and then the fiber web is reinforced into a cloth.Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric uses the piercing effect of a needle to reinforce the fluffy web into a cloth. Stitched non-woven fabric: It is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to align fiber webs, yarn layers, non-woven materials such as plastic sheets, plastic thin metal foils or Their combination is reinforced to make a non-woven fabric. Non-woven fabric is also called non-woven non-woven fabric, non-woven fabric, non-woven fabric textile, English is Nonwoven. Non-woven fabric is a textile composed of a fiber layer. This fiber layer can be a carded web or a thin fiber web directly made by a spinning method. The fibers are disorderly or oriented. Filter element.
