Problems solved by technology

One is inorganic oil-absorbing materials, mainly including graphite, activated carbon, bentonite, fly ash, etc. These materials are relatively cheap, but have small oil absorption and poor oil retention rate, and absorb oil and water at the same time.
The second is to synthesize organic oil-absorbing materials, the most widely used are high oil-absorbing resins, which have the advantages of fast oil absorption, high oil absorption rate, and strong oil retention capacity, but are expensive and difficult to biodegrade after use, which increases the environmental impact. The load will cause secondary pollution
The third is natural fiber oil-absorbing materials, mainly including kapok fiber, cattail fiber, bamboo pulp fiber, crop straw, cotton fiber, wool, etc. These materials are biodegradable, non-toxic, non-polluting, green and environmentally friendly, and have a wide range of sources, but If it is not treated with lipophilic and hydrophobic modification, it will also absorb water while absorbing oil, and water will occupy a large amount of oil storage space, which will limit the oil absorption capacity of the material
At present, the vast majority of flax waste is disposed of through soil burial or incineration, causing serious environmental pollution and waste of resources. Even if a small amount of flax waste is recycled, its reuse field is very limited
[0005] Flax is a natural fiber oil-absorbing material. Compared with other oil-absorbing materials, flax waste has a wide range of sources, is cheap, and can be biodegraded. However, there are a large number of hydroxyl groups in its molecular structure, which has high hydrophilicity, which limits its oil absorption performance and Application in oil-absorbing products

Abstract

The invention belongs to the technical field of functional textiles and particularly relates to a flax waste oil absorption material and a preparation method thereof as well as a non-woven oil absorption felt. The flax waste oil absorption material comprises oleophylic modified flax fibers and the flax fibers are selected from flax wastes. The preparation method adopts a chemical grafting method to carry out oleophylic and hydrophobic modification on the flax fibers. The non-woven oil absorption felt composed of the flax waste oil absorption material and polyester fibers has efficient and rapid oil absorption capability, can be repeatedly used for a plurality of times, and the aim of treating pollution with the wastes is realized.

Description

technical field [0001] The invention belongs to the technical field of functional textiles, and in particular relates to a linen waste oil-absorbing material, a preparation method thereof and a non-woven oil-absorbing felt. Background technique [0002] With the rapid development of industry, world trade and offshore oil exploitation, the occurrence of industrial oily sewage leakage and discharge, marine accidents and platform oil spills have caused serious pollution to water bodies, destroyed aquatic resources, and seriously affected the living environment of human beings. Material adsorption and recovery of waste oil are important means to solve oil pollution. [0003] Currently, there are three types of commonly used oil-absorbing materials. One is inorganic oil-absorbing materials, mainly including graphite, activated carbon, bentonite, fly ash, etc. These materials are relatively cheap, but have small oil absorption, poor oil retention rate, oil absorption and water ab...
