[0018] Example one
[0019] (1) Processing polypropylene spunbond non-woven fabric:
[0020] Polypropylene: polypropylene polymer + 10% environmentally friendly polypropylene flame-retardant masterbatch-high temperature melt extrusion of large screw stalks (the temperature of the first stage of the screw is 220℃, the temperature of the second stage of the screw is 260℃; the temperature of the third stage of the screw is 260℃—— Filter (using 600 mesh metal screen)-metering pump (quantitative melt output range: 200 liters / hour)-spinning (up and down drawing and suction at the spinning inlet)-air cooling-air traction- Net curtain formation-upper and lower rollers (pre-reinforcement)-hot rolling (reinforcement)-winding.
[0021] By controlling the thickness of the net curtain, it can be made into 200g / m 2 Of polypropylene.
[0022] (2) Printing
[0023] Use digital printing machine to print.
[0024] (3) Adhesive
[0025] Using a scraper coating process on the back of the spunbond non-woven...
Example Embodiment
[0026] Example two
[0027] (1) Processing polyester spunbond 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 stalks (the temperature of the first stage of the screw is 240 ℃, the temperature of the second stage of the screw is 300 ℃; the temperature of the third stage of the screw is 320 ℃)- Filter (using 1200 mesh metal screen)-metering pump (quantitative melt output range: 180 liters / hour)-spinning (up and down drawing and suction at the spinning inlet)-air cooling-air traction- Net curtain formation-upper and lower rollers (pre-reinforcement)-hot rolling (reinforcement)-winding.
[0029] By controlling the thickness of the net curtain, it is made into 70g / m 2 Of polyester spunbond nonwovens.
[0030] (2) Printing
[0031] Design printing patterns, using rotary screen printing machine to print.
[0032] (3) Adhesive
[0033] Using a ...
Example Embodiment
[0034] Example three
[0035] Polypropylene: polypropylene polymer + 5% environmentally friendly polypropylene flame-retardant masterbatch-high temperature melt extrusion of large screw stalks (the temperature of the first stage of the screw is 220℃, the temperature of the second stage of the screw is 240℃; the temperature of the third stage of the screw is 240℃—— Filter (using 800 mesh metal screen)-metering pump (quantitative melt output range: 200 liters / hour)-spinning (up and down drawing and suction at the spinning inlet)-air cooling-air traction- Net curtain formation-upper and lower rollers (pre-reinforcement)-hot rolling (reinforcement)-winding.
[0036] By controlling the thickness of the net curtain, it can be made into 80g / m 2 The flame retardant is added to the non-woven fabric through the impregnation process to improve the flame retardant effect of the product. The flame retardant used for polypropylene non-woven fabric is a mixed flame retardant of magnesium hydrox...
