Description

Dyeing and printing process

Technical Field

The invention relates to textile dyeing and printing technology, in particular to a dyeing and printing process method for a hydrophobic textile material.

Background

The dyeing and printing of textiles can be generally divided into dye dyeing, printing, pigment dyeing and printing. The dyeing and printing of dyes are usually carried out by the interaction of intermolecular force or active groups of the dyes themselves with the fibers. Pigment dyeing and printing are combined with the fabric in a physical bonding mode through a binder in pigment dyeing and printing paste. Generally speaking, dyed and printed products obtained after dye printing are more environment-friendly, low in formaldehyde content, bright in color and luster, good in color fastness, soft in hand feeling and non-sticky at printed parts; the paint printing process is simple, the printing cost is low, and three wastes are not generated basically.

The traditional dye dyeing and printing process generally comprises the following steps: textile → printing → drying → steaming → washing with water → reduction washing → soaping → washing with water → drying → finishing → printing the finished product. In the traditional dye dyeing and printing slurry, auxiliary products such as sodium alginate, sodium lignosulfonate, naphthalene sulfonic acid formaldehyde condensate, a dispersing agent, a leveling agent, a penetrating agent and the like with the amount of 1-1.5 times of the dye are usually required to be added, and the auxiliary products are stripped from the surface of the fiber by steps such as water washing, reduction washing, soaping and the like after the dyeing and printing processes are finished, so that the auxiliary products enter dyeing and printing wastewater. Meanwhile, in the traditional dyeing and printing processes, the dye-uptake of the dye is generally 90-95%, the rest 5-10% of the dye exists on the surface of the fiber in a loose color form after the dyeing and printing are finished, and the dye also enters the printing and dyeing wastewater in the processes of washing, reduction washing and soaping. The auxiliaries and dyes entering the dyeing and printing wastewater cause high COD and high chroma of the dyeing wastewater, the treatment difficulty is higher, the treatment cost is higher, according to the statistics of authoritative data, about 250 tons of water is consumed by a printing factory for processing one million meters of chemical fiber fabrics, and 90% of the water is color water and wastewater. The most effective measures at present only stay in emission reduction and post-treatment of colored water and sewage, and are not effectively eradicated. The printing and dyeing wastewater becomes an obstacle which troubles the sustainable development of textile printing and printing industries in China.

The paint printing process is much simpler than dye printing, generally comprises textile → printing → drying → baking → finishing → printing finished products, no water washing step is required in the printing process, drying and shrinkage control and cross contamination are realized, the removal of natural or synthetic paste, the existence of alkaline agent, surfactant and other pollutants can be ignored, and the process is environment-friendly dyeing and printing. However, the coloring component selected for pigment printing is generally pigment, which has no affinity with the fiber, needs to be adhered to the surface of the fiber through an adhesive, and the color cannot permeate into the fiber, so that the defects of poor color permeability, poor color fastness, washing fastness, hard hand feeling, poor yellowing resistance and the like of the pigment printing product are caused.

The invention combines the dye dyeing, printing, pigment dyeing and printing processes, takes the advantages of the dye dyeing, printing and pigment dyeing and printing processes into consideration, supplements the defects of the dye dyeing and printing processes, and is a new way for dyeing and printing.
