Fiber net forming continuous dyeing method

Abstract

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a fiber net forming continuous dyeing method. By means of the method, fibers are carded and subjected to impurity removal through a fiber lapping machine to be made into reticular fibers, and then continuous dyeing is carried out. The method comprises the steps that original loose fibers are fed into the lapping machine to be made into reticular fibers, then the reticular fibers enter a dyeing device of the same speed, dye is sprayed to the reticular fibers, the reticular fibers with the dye are conveyed through a belt clamping device and are extruded through a padder, one time of spraying and multiple times of rolling are achieved to arrange dye on the fibers, coiling and stacking arecarried out, and dyed fibers are obtained after washing and drying. By means of the method, the continuous process is adopted, operation from original loose fibers to dyeing is completed at one step,loose fibers are directly made into reticular fibers, spray rolling and dyeing are carried out, the bath ratio is small, operation s simple, time and labor are saved, dyeing uniformity is good, and the dyeing effect is good; and the use level of dye is small, the dye utilization rate is high, dyeing materials and auxiliaries are saved, and energy saving and environment protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a continuous dyeing method of fiber netting. Background technique [0002] Cellulose fiber is an important raw material for the textile industry. It is widely used because of its good properties such as strong hygroscopicity, good softness, good air permeability and wear resistance. With the continuous improvement of people's living standards, the demand for different fabrics is gradually increasing, and some of the fabrics are woven from fiber yarns of different colors. The fiber yarns of different colors need to be dyed by some special equipment. Traditional cotton fiber dyeing is divided into cheese dyeing and loose fiber dyeing. [0003] In the prior art, because cotton fiber belongs to short fiber, continuous production is relatively difficult, so usually pretreatment is performed first, and then non-continuous dye vat processing is used. Fo...

Problems solved by technology

However, the dyeing method involved in the above-mentioned prior art belongs to intermittent dyeing, which can only dye a certain amount of fibers at a time, and cannot carry out continuous dyeing.

At the same time, this dyeing method puts cotton loose fibers into the dyeing cage (or dyeing vat) during dyeing, and starts the circulating pump to circulate the dyeing liquid in the dyeing cage (or dyeing vat) for dyeing, but during the dyeing process, the dye is absorbed by the cotton Layers of fibers are hindered and cannot evenly enter the interior of the fibers, resulting in uneven dyeing, which will affect the final effect of cotton fiber dyeing
