Detailed Description
The principles and features of the present invention are described below in connection with the following examples and comparative experiments, which are presented for purposes of illustration only and are not intended to limit the scope of the invention.
The waterproof and antifouling fabric is woven by adopting a plain weave or twill weave mode, the monofilament diameter of the fabric thread is 80-120 mu m, and the gram weight is 385-445 g/m 2 . The thread with the above size and the weaving density with special design are adopted, the woven fabric is very compact, and the weaving gaps with small intervals and regularity can be formed under the condition that the surface is not coated with the waterproof coating, thereby being very beneficial to manufacturing the super-hydrophobic surface structure.
The fabric thread is formed by blending a core thread and an outer wrapping thread, wherein the outer wrapping thread is subjected to soaking treatment by a perfluorinated finishing agent and a cross-linking agent, and the core thread is not subjected to soaking treatment by a water repellent and antifouling finishing agent. The core wire comprises 50-55% of cotton, 20-25% of nylon, 20-25% of terylene and 3-5% of moisture conducting fibers. The outer wrapping wire comprises 35-40% of cotton, 20-30% of wear-resistant polyester, 25-30% of polyester cotton and 5-10% of hemp. The diameter of the core wire monofilament is 60-70 mu m, and the diameter of the outer wrapping wire monofilament is 17-21 mu m. The yarn for the fabric is spun in a blending mode of taking a core yarn as a main body and wrapping an outer wrapping yarn on the outer side.
The outer surface layer of the fabric is subjected to roughening treatment, and the surface layer of the fabric is sprayed with a waterproof adhesive layer through a spraying process. According to the invention, the waterproof glue layer is prepared by spraying the waterproof glue, but not by coating, and the prepared waterproof glue layer is not formed into a film, so that ventilation of the fabric is facilitated. The surface compactness of the fabric is precisely designed, weaving gaps are regular and the distance is extremely small, after roughening treatment, sprayed waterproof glue drops are adhered to a roughened surface formed by roughening and permeate into a roughening fiber group, and finally a regular waterproof glue particle layer formed by dense waterproof glue particles is formed on the surface of the fabric. Because the weaving gap of the fabric is accurately calculated, the waterproof glue drops are subjected to the action of surface tension in the drying process to form round-like flat colloidal particles, so that the size of the weaving gap is reduced, and finally the superhydrophobic surface is formed. Has excellent waterproof and antifouling effects.
Because the outer envelope is soaked by the perfluorinated finishing agent and the cross-linking agent, the outer envelope and the waterproof adhesive have better bonding performance, and meanwhile, the bonding strength can be further increased by the sanding treatment.
The invention relates to a waterproof and antifouling fabric, which comprises the following steps:
s1, preparing a core wire: according to the core wire proportion, short fiber raw materials are adopted, the raw materials are processed into threads through cotton grabbing, cotton mixing, combing and antistatic treatment, the threads obtained through treatment are processed through a soft finishing agent, and the core wires are obtained through dehydration and drying;
s2, preparing an outer envelope wire: according to the proportion of the outer wrapping wire, short fiber raw materials are adopted, the raw materials are processed into wires through cotton grabbing, cotton mixing, combing and antistatic treatment, the wires obtained through treatment are soaked through a perfluorinated finishing agent and a cross-linking agent, and the outer wrapping wire is obtained through dehydration and drying;
