Embodiment 1

[0026] The saturated impregnation production process of a waterproof and oil-repellent non-woven fabric involved in the present invention comprises the following steps: step S1 carding into a web, step S2 preparing an impregnating adhesive solution, step S3 impregnating the fiber web, step S4 drying and bonding, Finally, the dried waterproof and oil-proof non-woven fabric is wound and packed into the warehouse.

[0027] In the step S1 of carding into a web, the polyester fiber is carded into a web by means of mechanical carding and web laying. The mechanical carding used is a three-doffer output card; the fabric stripes of the formed fiber web are arranged in one direction. Using the Sandorf output carding machine can greatly improve the uniformity of the fibers for thin non-woven fabrics. After testing, the surface density unevenness of the fiber web can be reduced by 50%.

[0028] The rotating speed of the cylinder is 31Hz, the rotating speed of the upper doffer is 21Hz, t...

Abstract

The invention discloses a saturated impregnation production process of a waterproof and oil-proof non-woven fabric. The process comprises the following steps that carding is performed to form a web, the weight range of the formed fiber web is 50-55 g/m<3>; an impregnating adhesive liquid is prepared, wherein every 500 kg of the impregnating adhesive liquid contains 130-170 kg of resin glue, 40-60kg of polyvinyl alcohol, 10-20 kg of a waterproof and oil-proof agent and an appropriate amount of an antifoaming agent; the liquid content of the fiber web is 50-80%, and a drying cylinder is adoptedto dry the fiber web subjected to squeezing of a pressing roller. The waterproof and oil-proof non-woven fabric prepared by the production process has the advantages that the impregnating adhesive liquid contains the resin glue, the polyvinyl alcohol and the waterproof and oil-proof agent, so that a layer of film is formed on the surface of the non-woven fabric after the resin glue is dried, andthe waterproof and oil-proof effect of the non-woven fabric is better by combining the added waterproof and oil-proof agent; the used polyvinyl alcohol solves the problem of pilling on the surface ofthe non-woven fabric; the prepared waterproof and oil-proof non-woven fabric not only has the characteristics of good air permeability of the impregnated non-woven fabric, but also has the waterproofand oil-proof effect.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a saturated impregnation production process of waterproof and oil-proof non-woven fabric. Background technique [0002] Existing waterproof and oil-proof non-woven fabrics are produced by spun-bonding process. The waterproof and oil-proof non-woven fabrics produced by this method have poor air permeability, and the surface has lines and is easy to stick. The spunbond process is made of plastic masterbatch and the cloth surface is made by spinning. The fibers are fine and dense, and the cloth panel is knotted, which is not easy to breathe. Moreover, the general enterprises use patterned rolls, and the cloth surface has corresponding textures, which is waterproof and waterproof. Oil non-woven fabrics are easy to bond with textures. The advantage is that the spunbonded non-woven fabric has good water repellency and excellent vertical and horizontal strength. Si...
