The invention relates to a production technology for a high-wet modulus cotton pulp, which comprises the following steps: preparing raw materials: taking
cotton linters as the raw materials, opening, removing impurities, sending to a
cyclone separator by air, fully mixing the raw materials with alkali liquor, and then extruding and
dewatering; digesting: feeding
slurry soaked with the alkali liquor into a spherical digester for digesting; chloridizing: chloridizing the digested
slurry; bleaching: feeding the chloridized
slurry into a bleaching tank for bleaching, and concentrating the slurry by using a
concentrator before bleaching at the feeding moment; performing
acid treatment: performing the
acid treatment on the bleached cotton pulp and feeding
hydrochloric acid into the bleaching tank in a spraying mode; and obtaining an end product: making by using a paper maker and packing into the end product of the cotton pulp. According to the production technology provided by the invention, a dry
impurity-removing
machine is firstly utilized to fully separate, scatter and purify the slurry, and then the slurry enters into a spiral
sieve drum type extruder, and the cotton fibers are more uniformly soaked in the alkali liquor; the digesting uniformity is increased; the cost of the raw materials is low; the
processing process is simple; the operation is convenient; the
purchasing scope of the raw materials is wide and is unlimited; the output of
modal fiber products is increased; and the development of the
modal fiber industry is boosted.
