The tearing-resistant layer comprises a three-layer composite structure, wherein the three-layer composite structure comprises a graphene layer and two polyamide fiber layers; a graphene layer is sandwiched between two polyamide fiber layers, and the polyamide fiber is commonly called nylon and is characterized by good mechanical strength and corrosion resistance; but the defects are that the heat resistance of the material is poor, and the deformation of the fabric is easily caused under the outdoor sunshine exposure; meanwhile, the nylon material also has the problem of poor antistatic property, so that the antistatic property of the nylon material can be effectively improved by adding the graphene; the defects of the nylon material are made up by using the graphene material; meanwhile, the unidirectional moisture-conducting fabric is used for preparing the water-repellent surface for the purpose of water resistance, so that the water resistance of the oxford fabric can be effectively improved.
Based on the above purpose, the method provided by the invention improves and innovates the processing technology of oxford fabric, and specifically comprises the following steps:
step 100: preparing oxford;
step 200: preparing a tearing-resistant layer;
step 300: preparing a water repellent surface;
step 400: and (5) preparing hydrophilic surfaces.
Adding a polyamide fiber layer in the oxford fabric surface edge sealing treatment in the step 200; a graphene layer is coated on the surface of the polyamide fiber layer in a scraping mode; after the graphene layer is processed, the edge of the polyamide fiber layer is sealed again; compounding a scraped graphene layer by adopting the following special formula, namely compounding graphene slurry and decabromodiphenylethane into anti-tearing slurry, wherein the compounding ratio of the graphene to the decabromodiphenylethane is 1-2: 3-4; second configurationThe anti-tearing primer and the face glue are prepared from 70% of anti-tearing slurry, 22% of primer, 5% of cross-linking agent and 3% of accelerant, and the face glue is prepared from 5% of cross-linking agent, 3% of accelerant and 92% of face glue. After the last compounding is finished, respectively blade-coating the anti-tearing primer glue and the face glue on the polyamide fiber layer for 4 times, then blade-coating the face glue for one time, and baking for 3min at 120 ℃; the gram mass of the facing material is controlled to be increased by 120-150 g/m2. The anti-tearing layer constructed by the steps can effectively improve the performance of the oxford fabric, and the anti-tearing strength of the oxford fabric is improved by more than four times.
Based on the waterproof purpose, 75D/72f moisture absorption and sweat releasing yarns and 75D/72f polypropylene yarn terylene are adopted in the step 300 to form a water repellent surface after manufacturing, dyeing and finishing and sizing, and the principle is as follows: the polypropylene yarn and the polyester are interwoven, so that moisture or sweat enters the polyester surface from the polypropylene surface, but does not enter the polypropylene surface from the polyester surface, the unidirectional moisture-conducting effect can be achieved, and meanwhile, the polypropylene has the advantages of small density, light weight, hydrophobicity, quick drying, fouling prevention, deodorization, wear resistance, environmental protection, good chemical stability and the like. And finally, modifying the prepared water repellent surface by using a super-hydrophobic finishing liquid prepared from polydimethylsiloxane, nano ZnO and n-hexane by using a dip coating method to obtain a super-hydrophobic water repellent surface, and then edge-sealing the prepared water repellent surface to the oxford fabric by using an edge sealing process. Compared with the traditional oxford fabric, the strength and the waterproofness of the high-strength tear-resistant waterproof oxford fabric constructed by the steps are greatly improved.
