Description

Technical Field

[0001] The present invention relates to the field of clothing fabrics, and particularly to a clothing fabric containing spider silk and a preparation method thereof. Background Art

[0002] With the progress of science and technology, there have been new developments and advancements in the use of clothing materials. Spider silk fiber, as a new type of high-performance material, has good rigidity, elasticity, and strength. In addition, this new material is biodegradable, does not pollute the environment, and can re-enter the ecosystem. Therefore, the development prospect of this material is very good.

[0003] However, the antibacterial effect of cotton thread fabrics containing spider silk is not very significant, and there is little research in this regard. Moreover, general fabric modification is by impregnation. Due to the smooth surface of spider silk, the method of enhancing antibacterial properties by impregnating fabrics has poor antibacterial stability. Summary of the Invention

[0004] Aiming at the defects of the prior art, the purpose of the present invention is to provide a clothing fabric containing spider silk and a preparation method thereof to solve the problems raised in the above background art.

[0005] The present invention provides a clothing fabric containing spider silk. The clothing fabric uses modified spider silk as the first warp and weft textile yarn, and antibacterial cotton thread as the second warp and weft textile yarn. Then, the first warp and weft textile yarn and the second warp and weft textile yarn are woven by interlacing in the warp and weft directions to obtain a clothing fabric containing spider silk;

[0006] The preparation raw materials of the modified spider silk fiber include the following components in parts by weight:

[0007]

[0008] The mass concentration of the potassium permanganate aqueous solution is 20 - 80%.

[0009] Furthermore, the preparation steps of the modified spider silk fiber include:

[0010] S301: Weigh the spider silk, modified fullerene, nanocellulose, modified protamine, NH4I, boron nitride, and potassium permanganate aqueous solution according to the parts by weight;

[0011] S302: Put the spider silk and the potassium permanganate aqueous solution into a reaction kettle together, set the reaction conditions, and obtain intermediate product B;

[0012] S303: Pour the modified fullerene, nanocellulose, and NH4I into the intermediate product B in the reaction kettle, set the reaction conditions, and obtain intermediate product C;

[0013] S304: Pour the modified protamine and boron nitride into the intermediate product C in the reactor, set the reaction conditions, and after the reaction is completed, dry the modified spider silk to obtain the modified spider silk.

[0014] Furthermore, the reaction conditions of steps S302, S303 and S304 for preparing the modified spider silk fiber are all 80-150°C, 0.5-2h, continuous ultrasound during the reaction, and an ultrasound frequency of 40-70kHz.

[0015] Furthermore, the raw materials for preparing the modified fullerene include the following components in parts by weight:

[0016]

[0017] Among them, the mass concentration of sulfuric acid is ≥95%.

[0018] Furthermore, the preparation steps of the modified fullerene include:

[0019] S101: Weighing the fullerene, silane coupling agent, nano antimony dioxide and sulfuric acid according to weight parts;

[0020] S102: pouring the fullerene and sulfuric acid into a ball mill, setting reaction conditions, and preparing an intermediate product A;

[0021] S103: Pour the intermediate product A and nano antimony dioxide into a mixer, set reaction conditions, and prepare modified fullerene.

[0022] Furthermore, the setting conditions of the fullerene modification step S102 are that the ball mill speed is 200-1000 r / min and the reaction time is 0.2-2 h; the modification conditions of the fullerene modification step S102 are that the mixer temperature is 60-120° C., the speed is 200-2000 r / min, and the reaction time is 0.2-2 h.

[0023] The inventors of the present invention have found that the simple use of modified fullerene or modified protamine cannot satisfy the requirement of simultaneously ensuring the antibacterial performance of the fabric after aging treatment or salt water treatment; and when boron nitride is not added in the process of modifying spider silk, the antibacterial performance of the prepared fabric after aging treatment or salt water treatment is also reduced, indicating that boron nitride also has an effect on the antibacterial property of the fabric containing spider silk; in the process of preparing the fabric containing spider silk, modified fullerene and modified protamine are used simultaneously, and boron nitride is used in combination. Under the joint action of the three, the antibacterial property of the fabric can be greatly improved regardless of whether it is after aging treatment or salt water treatment. Experiments have found that in the process of preparing the fabric containing spider silk of the present invention, if any one of the three substances is lacking, the antibacterial stability of the fabric is greatly reduced.

[0024] Further, the raw materials for preparing the modified protamine include the following components in parts by weight:

[0025]

[0026] Further, the preparation steps of the modified protamine include:

[0027] S201: Weigh the protamine, trehalose, succinic acid glycoside and water according to parts by weight;

[0028] S202: Dissolve the protamine in water to obtain a protamine solution;

[0029] S203: Pour the protamine solution, trehalose and succinic acid glycoside into a reaction kettle, and set the reaction conditions to obtain the modified protamine.

[0030] Further, the reaction conditions for the preparation step S203 of the modified protamine are that the temperature is 60 - 150 °C, the reaction kettle is in a nitrogen protection environment, and the reaction time is 0.5 - 5 h.
