Rapid dyeing and drying process for loose fibers

Abstract

The invention discloses a rapid dyeing and drying process for loose fibers. The rapid dyeing and drying process for loose fibers comprises the following steps: (1) cake forming: loading the loose fibers into a loose fiber creel, and mounting the loose fiber creel in a drying barrel; (2) dyeing: guiding dye liquor in the drying barrel for dyeing; (3) drying: washing the loose fibers on the loose fiber creel, then carrying out water rolling treatment, and directly drying the loose fibers by using a fan device; (5) opening: after drying, hoisting out the loose fiber creel, and carrying out opening treatment on the fibers by an opening machine; and (6) packing. By the mode, continuous production can be implemented, dyeing, washing and drying procedures of the loose fibers are carried out in the same barrel, the production efficiency is greatly improved, the simulation of impurity attachment due to multi-step processing of the loose fibers can be avoided, then the dyeing quality of the loose fibers can be improved, and cotton fibers, wool fibers, scattered latex short fibers and the like which are not subjected to a carding and spinning procedure can be rapidly dyed by the process.

Description

technical field [0001] The invention relates to the field of dyeing technology, in particular to a fast dyeing and drying process for loose fibers. Background technique [0002] The loose fiber dyeing process refers to the dyeing process of cotton fibers, wool fibers and loose latex staple fibers that have not been carded and spun into colored yarns after being dyed first. Dyeing should be carried out in a special dyeing machine. A pump is used to alternately circulate the inside and outside of the dye liquor to obtain uniform dyeing, but the traditional loose fiber dyeing process requires multiple steps, and the loose fiber needs to go through the steps of beating-dyeing-topping-dehydration-opening-drying-packing , while dyeing, dehydration and drying are not completed in the same machine, greatly reducing work efficiency. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a rapid dyeing and drying process of lo...
