Problems solved by technology

The method of water-repellent treatment on one side of the fabric by spray processing can obtain a good water-repellent effect on one side for thicker fabrics, but it is difficult to apply water-absorbent and thinner pure cotton nonwoven fabrics. achieved on
Due to the large diameter of the droplets produced by spraying, the good water absorption characteristics of pure cotton nonwovens will make the water-repellent finishing agent spread rapidly on the surface of the nonwovens, making it difficult to achieve a regular arrangement of droplets on the surface of the nonwovens
And because the pure cotton non-woven fabric is very thin, the water-repellent finishing agent is easy to penetrate to the other side of the non-woven fabric, so that both sides of the non-woven fabric have water-repellent effect, and the non-woven fabric loses the function of water-repellent on one side.

preparation example Construction

[0033] A method for preparing pure cotton unidirectional moisture-conducting functional nonwoven fabric, characterized in that: the preparation method of pure cotton unidirectional moisture-conducting functional nonwoven fabric is as follows:

[0034] A Preparation of fluorine-containing water-repellent finishing agent solution 2

[0035] Dissolve the fluorine-containing water-repellent finishing agent in distilled water, and stir until it is uniformly dispersed to prepare a mixed solution with a mass fraction of the fluorine-containing water-repellent finish agent of 1% to 30%, and then add penetrant to the mixed solution, the penetrant The mass is 1 to 3 times that of the fluorine-containing water-repellent finishing agent, and the type is sodium α-alkenyl sulfonate or fatty alcohol polyvinyl chloride ether or sulfated castor oil or sodium alkyl sulfonate or sodium alkylbenzene sulfonate or sodium alkylsulfate, sodium secondary alkylsulfonate, sodium secondary alkylsulfate, ...

Embodiment 1

[0043] A Dissolve 1g of AG-XF fluorine-containing water repellent in 99g of distilled water, stir well until it is evenly dispersed, and make AG-XF

[0044] A mixed solution with a mass fraction of fluorine-containing water-repellent agent of 1%, and then 1 g of sodium α-olefin sulfonate penetrant was added to the mixed solution to obtain an AG-XF fluorine-containing water-repellent solution to be ultrasonically atomized.

[0045] B Place the ultrasonic atomizer in the AG-XF fluorine-containing water repellent solution for ultrasonic atomization to prepare AG-XF fluorine-containing water repellent atomized microbeads, and the particle size of the atomized microbeads is 10 μm.

[0046] C Place the pure cotton non-woven fabric on a glass plate, lay a 20-mesh screen on the upper surface of the pure cotton non-woven fabric, and place it in a container through a bracket to make the pure cotton non-woven fabric The woven cloth is in the middle of the container, and the AG-XF fluorin...

Embodiment 2

[0048] A Dissolve 1g of AG-XF fluorine-containing water repellent in 99g of distilled water, stir well until it is uniformly dispersed, and make a mixed solution of AG-XF fluorine-containing water repellent with a mass fraction of 1%, and then add 2g to the mixed solution Fatty alcohol polyvinyl chloride ether to obtain the AG-XF fluorine-containing repellent solution to be ultrasonically atomized.

[0049] B Place the ultrasonic atomizer in the AG-XF fluorine-containing water repellent solution for ultrasonic atomization to prepare AG-XF fluorine-containing water repellent atomized microbeads, and the particle size of the atomized microbeads is 10 μm.

Abstract

The invention relates to a production method for pure cotton single direction wet guiding functional nonwovens, which belongs to the technical field of textile. The production is a treatment method which is free of pollution, convenient and fast and comprises placing the pure cotton nonwovens in an atomization microbead environment with the water repellent effect, enabling atomization microbeads to slowly permeate from one sides of the nonwovens to the other sides of the nonwovens to obtain the single face water repellent effect of the pure cotton nonwovens to enable water repellent components in the pure cotton nonwovens to be distributed in graded mode, forming the good siphon effect, and producing the single direction wet guiding function. The method can effectively solve the problem that during the water repellent treatment process of the pure cotton nonwovens, due to the fact that the pure cotton nonwovens are thin, a water repellency finishing agent easily permeates to the other sides of the nonwovens, enables the both sides of the nonwovens to have the water repellent effect, and the single face water repellent function of the nonwovens. The prepared pure cotton nonwovens has the ideal single direction wet guiding function and are suitable for being used in medical and health products.

Description

technical field [0001] The invention provides a production method of pure cotton unidirectional moisture-wicking functional nonwoven fabric, which belongs to the technical field of textiles. Background technique [0002] With the rapid development of my country's economy and the improvement of living standards, people have higher and higher requirements for the functionality of clothing. The unidirectional moisture-wicking fabric can quickly transfer moisture or humidity from one side to the other side, keeping one side dry and cool at all times, and has become a functional fabric loved by the people. There are many ways to prepare unidirectional moisture-wicking functional fabrics, the main methods are by changing the structure of the fabric, changing the composition of the fabric and using water-repellent finishing. [0003] Patent 201010251734.9 discloses a production method of moisture-absorbing and sweat-wicking functional fabrics. 80% honeycomb moisture-absorbing and ...
