Problems solved by technology

However, the growth environment of the flock is different and the breeds are different, which leads to differences in the length and thickness of the wool fibers. At this stage, only the wool of good varieties can be fully utilized, and the rest of the wool fibers of poor quality can only be wasted.

Embodiment 1

[0026] A preparation method of waste wool fiber powder, the preparation method is: cutting waste wool loose fibers to 4-6mm, using Emax high-energy ball mill to grind for 2 minutes → pause for 3 minutes → grind for 2 minutes → pause for 3 minutes → grind for 2 minutes as one grinding , the rotating speed is 1100r / min, after the product obtained from the first grinding is cooled, the second grinding is carried out the same as the first grinding, and the waste wool fiber powder with an average particle size of 27.40μm is ground, and the particle size is scanned by laser instrument test, the results are shown in Table 1, and the performance test results of the prepared waste wool fiber powder are shown in Figure 1-4 .

Embodiment 2

[0030] The application of the waste wool fiber powder prepared by embodiment 1 in weaving, the application method is as follows:

[0031] 120g / m 2 Cotton fabric pretreatment, desizing treatment in boiling water at 100°C, drying at 80°C;

[0032] The waste wool fiber powder prepared in Example 1 and distilled water were used to obtain a wool powder suspension at 25g / L;

[0033] Soak the pretreated cotton fabric in the wool powder suspension for 15 minutes at a bath ratio of 1:35;

[0034] The cotton fabric was subjected to five-dip and five-pass padding with a sample padding machine, and the excess rate was 65%, and it was dried at 120°C for 15 minutes.

Abstract

The invention relates to waste wool fiber powder and its preparation method and application, belonging to the technical field of renewable resource utilization. The preparation method of the invention is as follows: cutting the waste wool loose fiber into pieces, and grinding it into powder by using a high-energy ball mill. The invention uses a high-energy ball mill to physically grind waste wool loose fibers directly into micro-nano-scale powders, which are applied to the finishing of textiles and recycled to produce high value-added products, finally realizing environmental protection and improving economic benefits Win-win.

Description

technical field [0001] The invention relates to waste wool fiber powder and its preparation method and application, belonging to the technical field of renewable resource utilization. Background technique [0002] my country has five major pastoral areas: Tibet, Inner Mongolia, Xinjiang, Gansu, and Qinghai, so it has a lot of wool resources. However, the growth environment and breeds of sheep are different, which leads to differences in the length and thickness of wool fibers. At this stage, only good breeds of wool can be fully utilized, and the rest of poor quality wool fibers can only be wasted. The recyclable resources such as waste wool and leftovers produced by my country's wool textile enterprises in the production process are increasing year by year, and the annual production of leftovers and thick and long wool can reach more than 100,000 tons. In addition, nearly 2 million tons of wool fibers are consumed every year. According to the principle of metabolism, nearl...
