Embodiment 1
[0062] Using 15g / ㎡ PLA spunbond fabric and softwood pulp as raw materials, first disperse softwood pulp fibers through a hydraulic pulper, after beating, adjust the concentration to 2%, store, and then use a metering pump to disperse the dispersed wood pulp The fiber and water are mixed and diluted to a concentration of three ten thousandths, and then transported to #1, #2 inclined wire formers, dehydrated to form a wet fiber layer with a dryness of 10%, and then transported by the first wet fiber at the bottom of the former. The web 2 and the second wet fiber transport web 6 are transported. Place the PLA spunbond fabric roll on the reinforcing layer unwinding device 4 in the middle of the #1, #2 inclined mesh former and unwind synchronously. The three fiber layers are stacked from bottom to top to form a sandwich fiber layer: the upper layer is 50g / ㎡wood pulp fiber layer, the middle is 15g / ㎡ PLA fiber layer, and the lower layer is 50g / ㎡ wood pulp fiber layer. Then the three...
Embodiment 2
[0064] Using 12g / ㎡ PP spunbond fabric and cotton pulp fiber raw materials, the cotton fibers are cut, degreased, and made into a 1% white cotton fiber slurry with a length of 2-3mm, and the cotton pulp raw materials are sent to The high-position slurry box is diluted with dilution water to a concentration of about three thousandths, and then further diluted with white water to a slurry and water mixture of five ten thousandths. The slurry is pumped to #1 Fourdrinier wire forming equipment and #2 Oblique wire forming equipment to remove the water in the slurry to form a fiber layer with a concentration of 30% and a weight of 145 grams. The first wet fiber conveying web 2 and the second wet fiber conveying web 6 at the bottom of the former are conveyed. At the same time, the PP coil is placed on the reinforcing layer unwinding device 4 in the middle of the #1 and #2 forming equipment to unwind synchronously, and the three fiber layers are stacked from bottom to top to form a sand...
Embodiment 3
[0066] Choose 25g / ㎡ ES hot-rolled cloth and 1.7d×5mm viscose fiber raw materials:
[0067] First, the chopped-cut viscose fiber is diluted and dispersed with water to a concentration of 2%, stored in a continuously stirred storage tank, and then sent to the front pool with a metering pump, and at the same time, reused white water is added to further dilute it to a three-thousandth concentration Mixture; then use the slurry pump to send the mixture to #1, #2 inclined wire formers, and add white water at the same time to reduce the concentration of the mixed material entering the inclined wire former to three ten thousandths, and then dewater it through 120 mesh forming wire , To form a wet fiber web with a fiber content of 50g / m2 and a dryness of 20%, which is then transported by the first wet fiber transport web 2 and the second wet fiber transport web 6 at the bottom of the former. At the same time, 25g / ㎡ of ES hot-rolled cloth is placed in rolls on the reinforcing layer unwindi...
