Spraying-type loose fiber treatment technology

Abstract

The invention relates to a spraying-type loose fiber treatment technology, and belongs to the technical field of loose fiber treatment. Loose fibers to be treated are placed on a treatment net, a plurality groups of rollers are arranged in the treatment net advancing direction, the rollers comprise the upper rollers and the lower rollers, the upper rollers and the lower rollers are arranged over and under the treatment net respectively, the central axes of the upper rollers and the central axes of the lower rollers are staggered, the central axes of the upper rollers penetrate through the lower rollers, the rotating direction of the upper rollers is opposite to that of the lower rollers, and then the loose fiber treatment net is dragged to advance; treatment liquid is sprayed downwards from the position over the upper rollers, and the loose fibers on the treatment net are delivered out after being treated. The spraying-type loose fiber treatment technology is applied to the processes of loose fiber dyeing, color fixing, cleaning, softening and the like and has the advantages of being low in energy consumption, large in treatment quantity, good in treatment effect and the like.

Description

technical field [0001] The invention relates to a spray type bulk fiber treatment process, which belongs to the technical field of bulk fiber treatment. Background technique [0002] Bulk fibers are usually dyed by dyeing vats. The bulk fibers to be dyed are put into dyeing cages, hung into the dyeing vats, and the temperature and time are controlled for dyeing treatment. The cleaning process needs to consume a lot of water, cleaning agent, etc., and the cleaning cost is relatively high; while the conventional water washing machine is mainly composed of a bathing pool and several pairs of upper and lower rollers arranged up and down, and the lower roller is located in the bathing pool. In the lotion, based on the structure of the washing machine, only the fabric or cloth can be washed, and the loose fiber is in a discontinuous state, so it cannot be washed with the existing washing machine. The dyed loose fiber can only be woven into fabric or After forming the net, the ove...

Problems solved by technology

[0002] Bulk fibers are usually dyed by dyeing vats. The bulk fibers to be dyed are put into dyeing cages, hung into the dyeing vats, and the temperature and time are controlled for dyeing treatment. The cleaning process needs to consume a lot of water, cleaning agent, etc., and the cleaning cost is relatively high; while the conventional water washing machine is mainly composed of a bathing pool and several pairs of upper and lower rollers arranged up and down, and the lower roller is located in the bathing pool. In the lotion, based on the structure of the washing machine, only the fabric or cloth can be washed, and the loose fiber is in a discontinuous state, so it cannot be washed with the existing washing machine. The dyed loose fiber can only be woven into fabric or After forming the net, the overall washing needs to go through multiple washings, the washing effect is not good, the water consumption is huge, and depending on the dye, hot water washing, alkali washing, soaping or even acid washing are required, and the washing cost is high

[0003] In view of the above-mentioned defects, there are also pouring-type water washing and pouring-type dyeing that adopt horizontal conveying, that is, the loose fibers are placed between the upper and lower nets, and the dyeing or washing of the loose fibers is realized through the extrusion of the two nets. Although this method overcomes the above-mentioned defects, in the process of processing, the driving roller speeds of the upper and lower nets are inconsistent, and the fiber web is easily broken; between the upper and lower nets, the fibers are subjected to a large extrusion force, resulting in a dense fiber web structure, which is difficult to clean. Or the dyeing cannot be completely completed; at the same time, because the dyeing or cleaning of the fiber is completed under the squeeze between the upper and lower nets, the thickness of the fiber web is limited, and the amount of fiber that can be processed is also limited
