The invention belongs to the technical field of
fiber modification, and particularly relates to a preparation method of degradable
biomass high-water-absorption short fibers. According to the invention,
cellulose short fibers such as
plant fibers,
regenerated cellulose fibers and the like are used as raw materials, and the degradable
biomass short fibers with high water absorption performance are prepared through the technological processes of pre-humidification, cake making, hanging into a reaction tank, alkalization, etherification,
neutralization, washing, oiling, wet feeding, wet splitting,
drying, metering, packaging and the like. The water
absorption rate of the obtained degradable
biomass high-water-absorption short
fiber is 60 to 100g / g, and the
fineness of the degradable biomass high-water-absorption short
fiber is 1.29 to 10.0 dtex. The fiber can meet the use requirements in the fields of hygienic
personal care products, blood-absorbing cotton medical dressings, surgical pads,
dirt treatment bags, water-blocking yarns and water-blocking tapes,
agriculture,
forestry,
landscaping, desert
greening, oil exploitation and the like, is an environment-friendly and renewable non-
petrochemical functional material, is green and environment-friendly, and has a very wide application prospect.
