[0002] Oxford fabric originated in the UK. It was named after the cotton fabric used in the student uniform shirts of Oxford University. Oxford fabric is mainly made of cotton yarn and polyester fiber (polyester) cross-woven. This combination makes Oxford fabric have the hygroscopicity and comfort of cotton, and the wear resistance and wrinkle resistance of polyester. Today, the development of Oxford fabric has become more mature, with the characteristics of easy washing and quick drying, soft feel, good hygroscopicity, and comfortable wearing. Not only that, Oxford fabric also has excellent wear resistance, fall resistance, and pressure resistance. These properties enable Oxford fabric to maintain excellent performance in various application scenarios. In the clothing industry, Oxford fabric is widely used to make shirts, sportswear, etc.; in the outdoor products industry, it is used to make suitcases, backpacks, tents, etc. In addition, Oxford fabric can also be used to make automotive interiors, furniture fabrics and other fields.

[0003] However, the Oxford fabric in the prior art still has the disadvantage of poor color fixing effect and lacks ultraviolet light protection effect. Under ultraviolet light irradiation conditions, conventional Oxford fabric not only lacks the protection function for the human body, but the color lake on the fabric is also easily decomposed, resulting in color change problems, affecting the appearance of the fabric. This is an urgent problem that needs to be solved in the prior art defects of Oxford fabric. Summary of the invention

The post-treatment liquid prepared by using sodium carbonate and the composite functional agent is used for color fixing treatment, and the finally prepared Oxford fabric is comfortable and skin-friendly, bright in color and has good color fixing effect.

[0019] The present invention uses 3,5-dihydroxytoluene and 2-hydroxybenzoyl chloride as raw materials, aluminum chloride as a catalyst, and performs Fries rearrangement to obtain an intermediate 1, and then uses the intermediate 1 as a raw material, N-succinimide as a halogenating agent, and benzoyl peroxide as an initiator to carry out a substitution reaction at the benzyl position of the intermediate 1 to carry a bromine atom to obtain an intermediate 2, and then the bromine atom of the intermediate 2 and the tertiary amine part of diallylmethylamine undergo a quaternary ammonium salt reaction to obtain an intermediate 3. At the same time, the present invention uses pyridine and 4-chlorobutene as raw materials to obtain an intermediate 4 through a quaternary ammonium salt reaction, and finally copolymerizes the intermediate 3, the intermediate 4, and diallylmethylamine under the action of a chelating agent, tetrasodium ethylenediaminetetraacetate, to obtain a composite functional agent; the composite functional agent itself is a macromolecular linear fiber structure, which is similar to the fiber structure of Oxford fabrics, and can play a good role on Oxford fabrics, and the composite functional agent contains a large number of quaternary ammonium salt structure cations The group can form an ionic bond with the anionic part of the dye to form a lake, so it can have a good color fixing effect. In addition, the composite functional agent also has a benzophenone structure, and the carbonyl group has multiple phenolic hydroxyl groups. When exposed to ultraviolet light, the carbonyl group of the composite functional agent can form an intramolecular hydrogen bond with the adjacent hydroxyl group to absorb ultraviolet light, turn itself into an excited state and release the energy of ultraviolet light in the form of heat energy. Therefore, it has a good absorption effect on ultraviolet light and has strong self-stability. Thanks to the macromolecular linear fiber structure of the composite functional agent, this ultraviolet light absorption effect is long-lasting and not easy to lose effectiveness due to washing. It can greatly improve the ultraviolet protection effect and durability of Oxford fabrics, and solve the problem of lake decomposition and color change caused by sunlight on Oxford fabrics, further improving the color fixing effect of Oxford fabrics. Not only that, the pyridine group in the composite functional agent can also give Oxford fabrics good antibacterial properties.

A method for preparing Oxford fabric with high color fastness, characterized in that: The following steps are involved: The first step: weigh the raw materials according to the mass proportions of PTT fiber 55-68 parts, bamboo charcoal fiber 25-30 parts, silk fiber 15-18 parts, sodium sulfate 5-6 parts, sodium carbonate 0.3-0.5 parts, and composite functional agent 0.6-1.3 parts, make the PTT fiber, bamboo charcoal fiber, and silk fiber into short fibers, and then use a high-speed winding machine to wind the short fibers, and after winding, use a double twisting machine to twist and shrink them for standby use; Step 2: The bobbins that have been shrunk in the first step are warped by a sectional warping machine, and then reeded to weave the Oxford spinning blank; Step 3: dissolving the composite functional agent and sodium carbonate in deionized water to obtain a post-treatment solution; Step 4: The Oxford spun fabric in the second step is put into the dyeing vat after being desized, and sodium sulfate is added to the dyeing vat, and the temperature is continuously raised to complete the dyeing; Step 5: Immerse the dyed Oxford fabric in a post-treatment solution, and dry it after immersion to obtain an Oxford fabric with high color fastness.

8. The method for preparing an Oxford fabric with high color fastness according to claim 7, characterized in that: The winding speed in the first step is 380-460 m / min, and the winding tension is set to 0.06-0.08 N; the twisting speed of the twisting machine is 7800-8600 r / min, and the twisting twist is 6-8 twists / cm.

9. The method for preparing an Oxford fabric with high color fastness according to claim 7, characterized in that: In the second step, the warping speed of the Oxford fabric is 80-120 m / min, the warp density of the Oxford fabric is 90-105 strands / cm, and the weft density is 40-55 strands / cm.

10. The method for preparing an Oxford fabric with high color fastness according to claim 7, characterized in that: In the fourth step, the dyeing temperature condition is 70-90°C, and the dyeing time condition is 30-45min; in the fifth step, the immersion temperature condition is 60-70°C, the immersion time condition is 30-60min, and the drying temperature condition is 130°C.
