Embodiment 1

[0019] (1) Processing polypropylene spunbond nonwoven fabric:

[0020] Polypropylene: polypropylene polymer + 10% environmentally friendly polypropylene flame retardant masterbatch - large screw high temperature melt extrusion (the temperature of the first section of the screw barrel is 220 ° C, the temperature of the second section of the screw barrel is 260 ° C; the temperature of the third section of the screw barrel is 260 ° C - Filter (use 600 mesh metal screen) - metering pump (melt quantitative output range: 200 liters / hour) - spinning (spinning inlet stretched up and down suction) - air cooling - air traction - Net curtain forming - upper and lower pressure rolls (pre-reinforcement) - rolling mill hot rolling (reinforcement) - coiling.

[0021] 200g / m is made by controlling the thickness of the mesh curtain 2 of polypropylene.

[0022] (2) printing

[0023] Printed on a digital printing machine.

[0024] (3) Adhesive

Embodiment 2

[0027] (1) Processing polyester spunbonded non-woven fabrics, the processes are as follows:

[0028] Polyester: polyester chips + 5% environmentally friendly polyester flame retardant masterbatch - high temperature melt extrusion of large screw (the temperature of the first section of the screw barrel is 240°C, the temperature of the second section of the screw barrel is 300°C; the temperature of the third section of the screw barrel is 320°C) - Filter (use 1200 mesh metal screen) - metering pump (quantitative output range of melt: 180 liters / hour) - spinning (spinning inlet stretches up and down for suction) - air cooling - air traction - Net curtain forming - upper and lower pressure rolls (pre-reinforcement) - rolling mill hot rolling (reinforcement) - coiling.

[0029] Through the control of the net thickness of the net curtain, it can be made into 70g / m 2 Polyester spunbond nonwovens.

Abstract

The invention mainly discloses a method for processing non-woven wall fabrics. The method includes steps of firstly, processing polypropylene or polyester spun-bonded non-woven fabrics; secondly, printing design patterns on the polypropylene or polyester spun-bonded non-woven fabrics; and thirdly, coating movable gum on back surfaces of the spun-bonded non-woven fabrics by a coating technique by the aid of a scraper. A technique for processing the polypropylene or polyester spun-bonded non-woven fabrics includes adding environment-friendly polypropylene flame-retardant master batches with the mass percent of 0-10% into polypropylene or polyester processed raw materials; mixing the environment-friendly polypropylene flame-retardant master batches and the polypropylene or polyester processed raw materials to obtain mixtures, and performing melt extrusion on the mixtures by a large screw; filtering the extruded mixtures by a filter which is a metal screen with 600-1200 meshes to obtain melt; quantitatively outputting the melt at the speed of 80-400 liters per hour by a metering pump; spinning the melt to obtain fibers; cooling the fibers by air; drafting the fibers by air flows; and forming nets of net curtains. The method has the advantages that new products manufactured by the method are excellent in flame-retardant effect, high in vapor permeability, convenient to assemble and disassemble and low in cost, and the like.

Description

technical field [0001] The invention relates to a processing method for a wall covering product, in particular to a processing method for a spun-bonded non-woven fabric wall covering which always has a flame-retardant effect. Background technique [0002] Early wall covering materials were mostly cashmere, Gobelin tapestry, gold-plated leather, velvet satin, etc., which were expensive and could not be popularized. Therefore, imitation wall coverings became popular, such as adding cashmere embossing instead of velvet wall coverings to cotton textiles. Embossed fabrics are used instead of Gobelin tapestries, wall coverings, etc. By the beginning of the 18th century, with the development of papermaking technology, paper wallpaper prevailed, and the printing mode transitioned from hand-drawn to stencil printing. In the 19th century, cheap wooden fibers were used to replace cotton fibers, and low-cost wall coverings appeared. In the 21st century, the wallpaper industry has comp...
