Plant fiber with high degradation speed and preparation method thereof

Abstract

The invention discloses plant fibers with high degradation speed and a preparation method thereof. The plant fibers comprise modified plant fibers, crop plants, a softening agent, a mildew preventive, an antioxidant and deionized water. The ethidene diamine increases the hygroscopicity of the fibers, so that carbon-oxygen double bonds are exposed under the sunlight, and the carbon-oxygen double bonds absorb ultraviolet rays, so that the bond energy of pectin is destroyed, thereby causing the loss of the integrity of the plant fibers and accelerating the degradation speed of the plant fibers in the nature; The hydrophobicity of the plant fibers is improved through the introduction of alkyl carbon chains, the hydrophobic carbon chains are mutually overlapped and intertwined to form a network, the toughness of the plant fibers is improved, and the flexibility and the elastic recovery of the lignin are changed by the n-butyl bromide; an acetone solution can remove oil cells in plant cells; stem tissues are separated from plant fiber precursors through cooking operation; the plant fibers prepared through the method have better flexibility, the degradation speed in nature is higher and better, and a large number of carbon sources and nitrogen sources are provided for soil on the premise that the environment is not polluted.

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a plant fiber with fast degradation speed and a preparation method thereof. Background technique [0002] The harm caused by the non-degradable plastic to the environment has prompted the birth of fibers. Environmentally friendly plant fibers are widely used. With the continuous research on plant fibers, some problems of plant fibers themselves have also surfaced. Plant fibers can degrade by themselves, but the rate of degradation needs to be improved. The self-degradation of plant fibers can only be decomposed into water and carbon dioxide, which cannot provide carbon and nitrogen sources for soil microorganisms to nourish the land, and the toughness and elasticity of plant fibers also need to be improved. . Therefore, it is necessary to design a plant fiber with fast degradation rate and excellent toughness and elasticity properties. Contents of the invention [0003] The ob...
