Description
Technical Field
The invention relates to the field of spunlace non-woven fabrics, in particular to a water-repellent non-woven fabric and a preparation method thereof.
Background
The spunlace nonwoven fabric is formed by jetting high-pressure micro water flow onto one or more layers of fiber webs to enable the fibers to be mutually entangled, so that the fiber webs are reinforced and have certain strength, and the obtained fabric is the spunlace nonwoven fabric.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below.
Example 1:
the raw material synthesis method for preparing the water-repellent non-woven fabric is as follows: polyethylene glycol (glycol) diacrylate) as a cross-linking agent, 10g N-isopropylacrylamide and 1g acrylamide monomer were dissolved in 100mL deionized water to form a reaction solution. After slowly stirring for 10 minutes, 50mL of tetramethylethylenediamine as a reaction accelerator was added to the above reaction solution, and finally, 5mL of an initiator KPS was added to the reaction mixture to initiate polymerization, and the polymerization was continued at 70 ℃ for 2 hours to obtain a whitish hydrogel-swollen crosslinked substance at the end of the reaction.
Since the gel may contain unreacted reagents, the residual water in the reaction mixture and the gel mass are completely removed by pressing the gel. The gel mass was cut into small pieces and transferred to a beaker containing sufficient distilled water and stirred at room temperature overnight. The washed swollen gel mass was recovered by centrifugation and again stirred in fresh water for at least 6 hours. Two long water washes were performed to purify the gel. The final pure swollen gel was recovered by centrifugation and transferred to a single-necked round-bottomed flask. The gel block was freeze-dried for 48 hours, and after drying, a dry bright white gel was obtained as a final product, a water-repellent gel.
Example 2:
a water-repellent gel was dissolved in an acetic acid solution to prepare a water-repellent gel solution (0.7 wt%), and mixed with trilaurate solutions (1 wt%) in different volume ratios and subjected to homogenization treatment to obtain a test solution, wherein a ═ water-repellent gel solution and B ═ trilaurate solution, specific ratios are as shown in table 1, for example:
TABLE 1 test solution ratio
| Ratio of | Test solution 1 | Test solution 2 | Test solution 3 | Test solution 4 |
| A:B | 5:1 | 7:1 | 10:1 | 15:1 |
The ratio of test solution, cotton fiber to polypropylene is shown in table 2:
TABLE 2 test solution, cotton fiber to polypropylene ratio
| Ratio of | Ratio 1 | Ratio 2 | Ratio 3 |
| C:D:E | 5:1:1 | 10:2:1 | 10:5:1 |
Wherein C is the test solution, D is cotton fiber, E is polypropylene fiber
In summary, the test solution 1, the test solution 2, the test solution 3 and the test solution 4 are proportioned 1-3, 1-3 and 1-3 respectively to form 12 groups to be detected, the spunlace nonwoven fabric is formed by processing the groups by a spunlace method, the manufacturing method is a known method, and the obtained wet fiber yarns are dried at 100 ℃ to obtain dry yarns (numbered as dry yarn test groups 1-12). And respectively spinning the dry filaments into cloth to be tested.
Example 3:
the sample is sampled above 20cm from the two ends of the whole fabric, the sampling length is 20cm X20 cm, the sample fabric is smooth and non-wrinkled, and defects influencing the test result cannot be generated. The test sample is equilibrated for 24h under atmospheric conditions with a humidity of 22-24 ℃ and a relative humidity of about 55%. Then the mixture is baked in an oven until the quality is constant and then tested.
The water repellency is measured by GB/T5553-2007 water spraying test. Experimental equipment: a water spraying standard tester; the method comprises the following operation steps: taking 3 waterproof treated test samples of 20cm multiplied by 20cm, fixing the test samples on a stretching frame to enable the fabric to form a smooth plane without wrinkles, and then fixing the stretching frame on a support of a measuring instrument, wherein the fabric faces upwards, and the center of a nozzle is aligned with the center of the stretching frame. Pouring 250mL of 27 +/-1 ℃ distilled water into the funnel quickly, completely pouring in 25-30 s, holding the stretcher frame immediately after pouring, tapping the other side of the stretcher frame, and then reversing 180 degrees and tapping once again to remove redundant water drops stuck on the surface of the fabric. Finally, the front surface of the sample is compared and rated with a standard wet card, and the test results are shown in table 3.
TABLE 3 Water repellency test results
The standard wet card scores were as follows:
100 minutes, the surface of the upper layer is not wetted or wetted;
and (5) 90 min: the surface of the upper layer is wetted or wetted irregularly with a small amount of water;
80 minutes: wetting the showering part on the upper layer surface;
70 min: part of oil wet exists on the whole upper surface;
and (3) 50 min: the whole upper surface is completely wetted;
20 min: partially wetting the entire upper surface;
0 minute: all upper surface was fully wetted and the surface subsided.
Test results show that when the ratio of the water-repellent gel solution to the trilaurate solution is 10:1 and the ratio of the test solution, the cotton fibers and the polypropylene fibers is 10:5:1, the water-repellent non-woven fabric obtained by spinning has the best water-repellent effect.
