Problems solved by technology

[0002] Non-woven fabrics are widely used due to their short process flow, fast production speed, high output, and low cost. However, due to their poor strength, the application range of non-woven fabrics is limited.
[0003] In order to solve the above problems, the reinforced non-woven fabric compounded with mesh cloth is usually used at present, but due to the interweaving of warp and weft yarns, the fibers are interwoven and bent, the effect of strength exertion is low, the strength increase is not high, and the manufacturing process is complicated, and the production cost is also high.

Embodiment 1

[0029] (1) Opening: The polyester staple fiber 1 is evenly sent into the cotton storage box, piled up in piles, and sent to the conventional opening equipment for loosening and dissociation, so as to achieve uniform opening.

[0030] (2) Carding: Carding the opened fibers obtained in the above step (1) on a carding machine at a speed of 12 m / min.

[0031] (3) Web laying: the carded fiber obtained in the above step (2) is formed into a fiber web with the required surface density under the action of a cylinder and a doffer, which are commonly used devices for conveying and carding. Add glass fiber reinforcing ribs 2 during the net laying process, and the ribs are evenly arranged at equal intervals.

[0032] (4) Saturated impregnation or foam impregnation adhesive: butyl acrylate 30kg, methyl methacrylate 70kg, N, N methylenebisacrylamide 5kg, sodium lauryl sulfate 1.5kg, OP-10 3kg, to 70kg of ionized water, 2kg of rosin soap, and 0.75kg of potassium persulfate are impregnated w...

Abstract

The invention relates to a reinforced nonwoven fabric and a production method thereof. Fibers are subjected to opening, carding and lapping by virtue of professional equipment, reinforcing ribs are added in the lapping process, and the reinforcing ribs are uniformly arranged at equal intervals or are arranged at unequal intervals. The fibers are impregnated with an adhesive in a saturated way or the fibers are impregnated with the adhesive by virtue of foams, thus the reinforced nonwoven fabric is obtained. The production method of the reinforced nonwoven fabric comprises the following steps: opening, carding, lapping, impregnating by the adhesive in a saturated way or by virtue of the foams, drying, slitting and packaging. The product produced by the invention has the advantages of high tension strength and low cost; and meanwhile, the production process and production equipment are simple, the technical performances are stable, and the practicability is strong.

Description

technical field [0001] The invention relates to a non-woven fabric and a production method thereof, in particular to a reinforced non-woven fabric with reinforcing ribs and a production method thereof. Background technique [0002] Non-woven fabrics are widely used due to their short process flow, fast production speed, high output, and low cost, but their poor strength limits the scope of application of non-woven fabrics. [0003] In order to solve the above problems, the reinforced non-woven fabric compounded with mesh cloth is usually used at present, but due to the interweaving of warp and weft yarns, the fibers are interwoven and bent, the effect of strength exertion is low, the strength increase is not high, and the manufacturing process is complicated, and the production cost is also high. . Contents of the invention [0004] The object of the present invention is to provide a reinforced non-woven fabric and its production method. In order to increase the tensile ...
