Embodiment 1

[0018] The needle-punched carpet manufacturing process of the present invention adopts chemical fiber short filaments composed of 96% polypropylene staple fibers and 4% polyester staple fibers as raw materials, and uses 9.2% carboxylated styrene-butadiene rubber, 65.9% The glue solution that the thickener of calcium carbonate, 2.4% and 22.5% water forms is produced by the following steps:

[0019] First, loosen, mix, comb, and lay the short chemical fiber filaments to form a uniform fiber net, and then use needle punching to consolidate; then use the OD-SD25 flower-shaped needle-loom machine from Dilo, Germany, and select extended fork-shaped needles One side of the fiber web is needle-punched and raised; another example figure 1 As shown, the fiber web is transported to the gap between the impregnating roll 3 and the nip roll 2 through the guide roll 1, the unraised side of the fiber web is in contact with the surface of the impregnating roll 3, and the impregnating roll 3 is...

Embodiment 2

[0024] The difference between this embodiment and Example 1 is that: the chemical fiber staple fiber composed of 90% by mass percentage of polypropylene staple fiber and 10% of polyester staple fiber is used as raw material, and the carboxylated styrene-butadiene rubber with a mass percentage of 15.4% is used , 76.8% calcium carbonate, 1.9% thickener and 5.9% water, the walking speed of the fiber web during the gluing process is 3.5m / min.

[0025] Through experimental detection, the performance of the needle-punched carpet produced by the manufacturing process of this embodiment is as follows:

[0026]

[0027] As can be seen from the experimental data in the table above, the needle-punched carpet produced by the manufacturing process of the present invention has a relatively high breaking strength and elongation at break, and the strength and toughness of the carpet are relatively large, and the change in appearance is tested by a four-legged roller tester. The first-class...

Abstract

The invention relates to a manufacturing technique of a needle-punched carpet used for river sand panning and aims to enable the carpet manufactured by using the technique to have excellent washing-resistant and water-soaking resistant properties. Chemical fiber staples consisting of 90-96% by weight of polypropylene staples and 4-10% by weight of polyester staples are used as the raw materials in the manufacturing technique of the needle-punched carpet, which has the following steps of: 1, loosing, mixing, carding and spreading the chemical fiber staples to form an uniform fiber web, then fixing by needle-punching; 2, carrying out needle-punching raising on one side of the fiber web; 3, coating a glue solution composed of carboxy-D benzene glue, calcium carbonate, a thickening agent and water to the un-raised side of the fiber web by a glue feeding device, wherein the glue solution comprises the following components in percentage by weight: 9.2-15.4% of carboxy-D benzene glue, 65.9-76.8% of calcium carbonate, 1.9-2.4% of thickening agent and the balance of water, and the moving speed of the fiber web in the glue feeding device is 3.5-4m / min; and 4, drying.

Description

technical field [0001] The invention relates to a manufacturing process of a needle-punched carpet, in particular to a manufacturing process of a needle-punched carpet used for river sand gold panning. Background technique [0002] The manufacturing process of needle-punched river sand gold panning carpets in the prior art is as follows: polyester short filaments are used as raw materials, and a uniform fiber web is formed through the processes of opening, mixing, carding, and laying, and then needle-punched. Machine consolidation, piled on the front to form a gray cloth, and then glued on the back, dried and shaped to form a finished carpet. [0003] The weight of the unit product of the carpet manufactured by the above process is less than 1000g / ㎡, and the performance of the carpet against washing and soaking in water is not good. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a manufacturing process of needl...
