The invention provides a modified coconut shell
fiber, a preparation method thereof and application of the modified coconut shell
fiber in environment-friendly pet padding, and relates to the technical field of environment-friendly pet padding. The modified coconut shell
fiber is prepared from
fresh coconut shells as raw materials through pretreatment,
steam explosion, rapid
drying, crushing, grading and screening. The
moisture content of the
fresh coconut shells is 50-85%.
Fresh coconut shells are used as raw materials, a porous structure is formed by adopting a
steam explosion technology, natural
polysaccharide colloid is reserved, the adhesiveness is improved, and micron-sized pores reserved through rapid
drying are combined, so that the fiber has excellent water absorption and speed. According to the fiber, physical adsorption and
chemical adsorption of
oxygen-containing functional groups cooperate to efficiently deodorize, and
mildew and
insect pests are avoided through high-temperature steam treatment. The obtained fiber is safe and
pollution-free, can be used as a
raw material of a high-performance pet padding, has the advantages of fast water absorption, strong deodorization, low dust,
mildew resistance and the like, and has a good application prospect and a high economic value.
