Abstract
The invention provides a waterproof fabric and a preparation method thereof, and belongs to the technical field of fabrics. And (3) mixing cotton fibers and bamboo carbon fibers in proportion to prepare yarns, drying and weaving to prepare the blended fabric, and then soaking and rolling the blended fabric in a waterproof finishing agent for finishing, heating and shaping to prepare the waterproof fabric. The waterproof finishing agent prepared by the invention not only can obviously improve the waterproof performance of the fabric, but also can improve the mechanical property and the flame retardant property of the fabric, is soft and breathable, is comfortable to use and has wide application prospect.
Description
Technical Field
The invention relates to the technical field of fabrics, in particular to a waterproof fabric and a preparation method thereof.
Background
Along with the development of science and technology, the improvement of society and the improvement of living standard, the requirements of people on living quality are higher and higher. The textile has been extended from the basic function of shielding body against cold to the functions of beautiful, comfortable, fashionable, protecting, etc., the consumption concept of people is gradually developed from practical use to health care, environmental protection and multifunction, various intelligent and functional textiles are widely focused and developed, and waterproof moisture permeable textiles are one example.
The laminated fabric is a waterproof and moisture permeable laminated fabric formed by compounding a microporous film or a hydrophilic and non-porous film or a composite film of the microporous film or the hydrophilic and non-porous film and the film with a special adhesive and a fabric (woven fabric, knitted fabric, non-woven fabric and functional fabric thereof) through a lamination process. Lamination is a method of applying a layer of adhesive to a substrate, coating a layer of film or other material, and heating and pressurizing to form a two or more layers of composite fabric. The fabric layer of the waterproof and moisture permeable laminated fabric adopts fabric with a certain water-repellent effect, but the water-repellent effect of the fabric layer is far less than the requirement of protective clothing, and the moisture absorption of the fabric layer can increase the wet weight of the fabric, so that the fabric layer of the fabric needs to be subjected to water-repellent finishing.
The existing water-repellent finishing generally uses organic fluorine as a waterproofing agent, and fluorine-containing monomers have adverse factors to the environment, so that the waterproofing agent of organosilicon becomes a hot spot.
Disclosure of Invention
The invention aims to provide a waterproof fabric and a preparation method thereof, which can obviously improve the waterproof performance of the fabric, can also improve the mechanical property and flame retardant property of the fabric, is soft and breathable, is comfortable to use and has wide application prospect.
The technical scheme of the invention is realized as follows:
the invention provides a preparation method of waterproof fabric, which comprises the steps of mixing cotton fibers and bamboo charcoal fibers in proportion to prepare yarns, drying and weaving to prepare blended fabric, then soaking and padding with a waterproof finishing agent for finishing, and heating and shaping to prepare the waterproof fabric.
As a further improvement of the invention, the preparation method of the waterproof finishing agent comprises the following steps: mixing stearyl methacrylate, glycidyl methacrylate, N-methyl chitosan propyl acrylate, meta-dimethyl siloxane propyl acrylate, deionized water and a surfactant uniformly, heating and stirring, introducing inert gas, dropwise adding an initiator solution, carrying out heat preservation reaction, cooling to room temperature to obtain emulsion, adding a waterproof synergistic agent P, and stirring and mixing uniformly to obtain the waterproof finishing agent.
As a further improvement of the invention, the mass ratio of the stearyl methacrylate, the glycidyl methacrylate, the N-methyl chitosan propyl acrylate, the meta-dimethylsiloxane propyl acrylate, the deionized water, the surfactant and the initiator is 10-12:15-17:7-10:5-7:40-50:2-3:0.2-0.3.
As a further improvement of the invention, the heating temperature is 50-70 ℃, and the time of the heat preservation reaction is 2-3h.
As a further improvement of the present invention, the surfactant includes a tween series selected from at least one of tween-20, tween-40, tween-60, tween-80; the span system is at least one selected from span-20, span-40, span-60 and span-80, preferably, the surfactant comprises tween-80 and span-20, and the mass ratio is 3-5:2.
As a further improvement of the present invention, the initiator is at least one selected from the group consisting of potassium persulfate, sodium persulfate, and ammonium persulfate.
