The invention discloses a preparation method of
moisture-absorbing heating fibers containing
plant extracts and having an antibacterial function, which comprises the following steps: step 1, preparation of a
spinning solution: mixing
cellulose pulp with
alpha cellulose according to a weight ratio of 1: 2, then adding 10-18% of a composite modified additive, stirring at a high speed by using a stirrer to realize blending to prepare a blended
spinning solution, and standing, defoaming, and
ripening for later use; and 2)
spinning and forming: in which the spinning solution obtained in the first step is treated through a
metering pump and a filter, the spinning speed is preset, the spinning solution is sprayed out through a spinning
nozzle, enters a coagulating bath and reacts with reagents in the coagulating bath to be cured, and formed
fiber bundles need to be stretched through a drafting roller firstly and then subjected to post-
processing treatment. The product is fine, soft,
moisture-preserving, breathable, non-irritating to
skin affinity, excellent in
moisture absorption and heating performance and
antibacterial property, green, environment-friendly, biodegradable, free of
heavy metals and harmful chemicals, safe and non-dissolving out; and the
fiber has high
moisture regain and high hygroscopicity.
