Problems solved by technology

Traditional water-absorbing sanitary products are generally composed of hydrophilic non-woven fabrics, toilet paper, wood pulp short fibers, superabsorbent resins, and waterproof membranes. The production process is relatively complicated; Poor inter-partition bonding results in the overflow of wood pulp short fibers or super absorbent resin and other components in the product, which affects the usability and sanitation of the product

Embodiment 1

[0020] Wet-laid pulp fiber layer: First, pulp cardboard and different long fibers are added to the material tank according to a predetermined ratio of 8:2 and mixed thoroughly, and the mixed solution is input into the conical pulp distributor through the pulp pump, and then The fiber net is formed on the forming net curtain, and the fiber net is rapidly dehydrated under the action of negative pressure suction to form a pulp fiber net with initial strength. The speed of pulp wet forming is 80:160m / min, the pressure of forming head is 45bar, and the pressure value of negative pressure suction box is 65%.

[0021] Polypropylene spunbond cloth layer: Polypropylene long fibers are made by electrostatic separation process. The raw materials are sucked into the hopper by the vacuum pump and fed into the screw extruder. After being extruded by the screw, the raw materials are accurately added to the spinning In the wire box, after spinning, after cooling, drawing, electrostatic separa...

Embodiment 2

[0025] Wet-laid pulp fiber layer: firstly, pulp cardboard is added to the material tank according to the proportion of 100% and fully mixed, and the mixed liquid is input into the conical pulper through the pulping pump, and the fiber web is formed on the forming screen curtain , The fiber web is rapidly dehydrated under the action of negative pressure suction to form a pulp fiber web with initial strength. The speed of pulp wet forming is 160m / min, the pressure of forming head is 45bar, and the pressure value of negative pressure suction box is 65%.

[0026] Polypropylene spunbond cloth layer: Polypropylene long fibers are made by electrostatic separation process. The raw materials are sucked into the hopper by the vacuum pump and fed into the screw extruder. After being extruded by the screw, the raw materials are accurately added to the spinning In the wire box, after spinning, after cooling, drawing, electrostatic separation and other processes, the final forming mesh curt...

Abstract

The invention relates to a three-layer composite water-absorption pad non-woven fabric and a production method. According to the three-layer composite water-absorption pad non-woven fabric, polypropylene spunbond cloth and pulp composite cloth are taken as base materials and coated with a low-density polypropylene film. By taking a polypropylene spunbond cloth layer as a support layer, a product has very strong power, one side of the composited product has excellent water absorption property, and the other side of the composited product has anti-sliding and waterproof effects. Pulp fibers have super-hygroscopicity, the non-woven fabric is endowed with the super-hygroscopicity through spunlacing, and one side of the polypropylene spunbond cloth of the spunlaced product is coated with the film, so that the integral adhesiveness of the composite product is guaranteed, and the hygroscopicity and barrier property of the composite product are guaranteed. By utilizing a cross-pattern embossing roller, each layer of the product is well laminated, and meanwhile, the product has good skid resistance and wear resistance and a novel pattern appearance. The polypropylene spunbond cloth and the polyethylene film can be prepared into colored products, so that the composite product is integrally colorful and can meet various requirements of customers.

Description

technical field [0001] The invention relates to a three-layer composite water-absorbing pad non-woven fabric. The non-woven fabric is composed of a spunbond base fabric and a cellulose short fiber layer through a wet process, and then self-adhesive through a laminating process, and then embossed. The process forms a cross pattern, which belongs to the field of non-woven fabric manufacturing. Background technique [0002] Laminated nonwoven products have good barrier and waterproof properties, and are widely used in medical, hygiene and protection fields. Traditional water-absorbing sanitary products are generally composed of hydrophilic non-woven fabrics, toilet paper, wood pulp short fibers, superabsorbent resins, and waterproof membranes. The production process is relatively complicated; Poor inter-partition bonding results in the overflow of wood pulp short fibers or superabsorbent resin and other components in the product, which affects the usability and sanitation of t...
