Embodiment 1

[0024] see figure 1 , shows the flow chart of the milk protein composite fiber preparation method of the embodiment of the present invention, the method includes the following steps:

[0025] 1) Pretreatment of cotton fiber: add sodium hydroxide solution to cotton fiber, at room temperature, ultrasonically vibrate for 30-50s, filter and rinse;

[0026] 2) Reduction of cotton fibers: adding the cotton fibers treated in step 1) into the sodium periodate solution, stirring for 2-4 hours, filtering, and rinsing to obtain modified cotton fibers;

[0027] 3) Preparation of milk protein liquid: prepare sodium hydroxide solution, add olive oil to the sodium hydroxide solution, stir and mix at 30-50°C for 3-10 hours, then add milk, stir for 5-30 minutes, filter to remove solid matter to obtain milk protein liquid, and the amount of olive oil is 2 to 3 times of the weight of the sodium hydroxide solution;

[0028] 4) Add the modified cotton fiber prepared in step 2) to the milk protei...

Embodiment 2

[0040] The milk protein composite fiber preparation method, fiber and application provided in this example are basically the same as those in Example 1, except that:

[0041] 1) Pretreatment of cotton fibers: adding a sodium hydroxide solution with a concentration of 15% by weight into the cotton fibers, the sodium hydroxide solution will completely immerse the cotton fibers, at room temperature, ultrasonically vibrate for 30s, filter, and rinse with deionized water 3 times;

[0042] 2) Reduction of cotton fiber: immerse the cotton fiber treated in step 1) into a sodium periodate solution with a concentration of 0.05% by weight, under dark conditions, stir and react for 2h, filter, and rinse with deionized water for 5 times , to obtain modified cotton fiber;

[0043] 3) Preparation of milk protein liquid: prepare sodium hydroxide solution, add olive oil to the sodium hydroxide solution, stir and mix at 30°C for 3 hours, then add milk, stir for 5 minutes, filter to remove solids...

Embodiment 3

[0047] The milk protein composite fiber preparation method, fiber and application provided in this example are basically the same as those in Example 1 or 2, except that:

[0048] 1) Pretreatment of cotton fiber: adding a sodium hydroxide solution with a weight percentage concentration of 20% to the cotton fiber, the sodium hydroxide solution will completely immerse the cotton fiber, at room temperature, ultrasonically vibrate for 40s, filter, and rinse with deionized water 3 times;

[0049] 2) Reduction of cotton fiber: immerse the cotton fiber treated in step 1) into a sodium periodate solution with a concentration of 0.12% by weight, under dark conditions, stir and react for 3h, filter, and rinse with deionized water for 5 times , to obtain modified cotton fiber;

[0050] 3) Preparation of milk protein liquid: configure sodium hydroxide solution, add olive oil to the sodium hydroxide solution, stir and mix at 40°C for 8 hours, then add milk, stir for 20 minutes, filter to ...

Abstract

A provided preparation method for milk protein composite fiber comprises the following steps: pre-treatment on cotton fiber, preparation of a reduction milk protein solution of cotton fiber, and preparation of milk protein composite fiber. The preparation method for the milk protein composite fiber is easily available in raw materials, compact in reaction steps, easily controllable in process and strong in technology maneuverability and repeatability. The invention also provides the milk protein composite fiber which comprises cotton fiber at the core and milk protein at the external surface of cotton fiber, and application of the milk protein composite fiber as a clothes material. When a garment made from the provided composite fiber is worn on a body, milk protein directly contacts skin, the skin-friendly property is better than that of conventional plant fiber, and also the garment has gloss of silk and is strong in sweat absorbing property, good in dimension stability and low in cost. According to the application of the milk protein composite fiber, the milk protein composite fiber is applicable to prepare intimate apparels, such as bras, underpants, small vests and summer clothes.

Description

technical field [0001] The invention relates to the field of textile industrial materials, in particular to a preparation method of milk protein composite fiber, milk protein composite fiber and application thereof. Background technique [0002] Nowadays, with the decrease of fossil fuels such as petroleum, the price has also risen accordingly, and the cost of synthetic fibers that completely rely on fossil fuels has also gradually increased, and the growth of quantity is greatly restricted. On the other hand, synthetic fibers also have their natural shortcomings. , such as poor skin affinity, and the comfort is inferior to natural fibers. Therefore, natural fibers have become the first choice for people to pursue a comfortable life. However, natural fibers such as silk are expensive, and the skin-friendly properties of cotton are not perfect. Therefore, natural functional textiles have gradually become the mainstream of the market. How to restructure or modify existing natu...
