The invention adopts a high-energy ball mill and a physical grinding method to directly prepare the waste wool loose fibers into micro-nano powder, and the micro-nano powder is applied to the after-finishing of textiles and is recycled to produce products with high added values, thereby finally realizing the win-win of environmental protection and economic benefit improvement.
Description
Technical Field
The invention relates to waste wool fiber powder and a preparation method and application thereof, belonging to the technical field of renewable resource utilization.
Background
China has five pasturing areas, namely Tibet, inner Mongolia, Sinkiang, Gansu and Qinghai, so that the China has a large amount of wool resources. However, the growth environments of flocks of sheep are different and the varieties are different, which causes the difference of the length and the thickness of wool fibers, only good varieties of wool can be fully utilized at the present stage, and the rest wool fibers with poor quality can only be wasted. Recyclable resources such as waste wool and leftover materials thereof generated in the production process of wool textile enterprises in China are increasing year by year, and the leftover materials and thick and long wool generated every year can reach more than one hundred thousand tons. In addition, nearly 200 million tons of wool fibers are consumed every year, and nearly 200 million tons of waste wool is generated every year according to the metabolism principle. In a word, the waste wool resources in China are very large, if the waste wool fibers can be utilized, the waste of the wool resources can be reduced, considerable economic benefits can be brought, and the problem of environmental pollution caused by the waste wool fibers is also avoided.
In addition, wool fiber is a natural protein fiber containing a large amount of keratin components. Keratin can be applied to the aspects of textile finishing, composite materials, biomedical materials, protein films and the like, and the keratin has low content in the nature and is difficult to obtain, so the keratin is imperative to the recycling of keratin components in waste wool fibers.

The invention preferably uses the high energy ball mill to grind twice.
The invention preferably carries out the first grinding, the second grinding and the cooling after the obtained product is cooled.
The invention preferably provides that the powder has an average particle size of 20 to 30 μm.
The invention also aims to provide the waste wool fiber powder prepared by the method.
The invention also aims to provide application of the waste wool fiber powder in spinning.
The application method of the invention is preferably as follows: firstly, preparing a wool powder suspension by using waste wool fiber powder and water according to a ratio of 20-30g/L, and then mixing the waste wool fiber powder and the water according to a bath ratio of 1: 30-40, soaking the pretreated cotton fabric in the wool powder suspension, then carrying out padding finishing of five-padding and five-padding on the cotton fabric by using a padder, wherein the padding rate is 60-70%, and finally drying.
The invention preferably adopts the pretreatment method of the cotton fabric as follows: desizing in boiling water, and drying to obtain 80-160g/m cotton fabric2。
The invention has the beneficial effects that:
at present, a plurality of methods mostly adopt a chemical method or a chemical-mechanical method to prepare wool powder, and the prepared wool powder is mostly used for fiber blending or the research of various films and plastics.
The invention adopts a high-energy ball mill and a physical grinding method to directly prepare the waste wool loose fibers into micro-nano powder, and the micro-nano powder is applied to the after-finishing of textiles and is recycled to produce products with high added values, thereby finally realizing the win-win of environmental protection and economic benefit improvement.
