Abstract
The invention discloses a dyeing method of cotton fabrics, which adopts fluorescent paints to obtain fluorescence color. The dyeing method is characterized in that the cotton fabrics subjected to pretreatment are dyed and subjected to color fixation through the cationization modified fluorescent paints. According to the dyeing method, the cationization modification on the fluorescent paints is carried out, so that the fibrous color yield of the paints is improved, the cationization modification on fibers is avoided, the processes are shortened, the aims of energy conservation and emission reduction are fulfilled, and the uniform dyeing property is improved at the same time.
Description
Technical field
The present invention relates to a kind of fluorescent paint exhaust processes of COTTON FABRIC, belong to technical field of textile printing.
Background technology
The dyeing of COTTON FABRIC is mainly based on REACTIVE DYES, and REACTIVE DYES is bright in colour with it, fastness is good, easy to use, cheap and famous.But REACTIVE DYES always also exists exhaustion rate, problem that degree of fixation is lower.Meanwhile, in dyeing course, need to add a large amount of neutral electrolyte and promote upper dye, need to add a large amount of alkaline agents and carry out fixation, add the difficulty of wastewater treatment.Relative to traditional dyeing technology, pigment dyeing is the clean process technology of a sustainable development, it has, and flow process is short, energy-conservation, water saving, the feature such as low in the pollution of the environment, there is significant advantage in energy saving standard.In addition, pigment dyeing also has unique style, has a extensive future.Especially fluorescent paint compensate for the disappearance of REACTIVE DYES in chromatogram, can obtain and dazzle beautiful, bright-coloured fluorescent staining effect.
Commercial optical coating is generally with negative charge, to cotton fiber without affinity, can not spontaneous upper dye fiber when adopting dip-dye mode to dye, conventional method is after cotton fiber is first carried out cation modifying with cation modifier, carry out dyeing and fixation with fluorescent paint again, as Chinese patent CN 103590261A, CN 104074054A etc.This technology process long flow path, water consumption, energy consumption are large, easily cause uneven dyeing.The present invention, by cation modifying to fluorescent paint, improves the tinctorial yield of coating on fiber, and what avoid fiber is cation-modified, shortens technological process, reaches the object of energy-saving and emission-reduction, improve level-dyeing property simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of fluorescent paint colouring method of COTTON FABRIC, by the cation modifying to fluorescent paint, improve the tinctorial yield of coating on fiber, what avoid fiber is cation-modified, shortens technological process, realizes energy-saving and emission-reduction.
The present invention is by the following technical solutions: by the COTTON FABRIC through pre-treatments such as destarch, kiering, bleaching, biopolishings, directly dye with the fluorescent paint through cation modifying, and carry out fixation treatment with adhesive.
Described pre-treatment routinely technique adopts the auxiliary agents such as hydrogen peroxide, alkali, cellulase to carry out destarch, kiering, bleaching, biopolishing etc.
The cation modifying of described fluorescent paint, modified technique: fluorescent paint 1 ~ 10% (to fabric weight), cation modifier Fix-8005 ~ 30% (to coating weight), paregal O 2 ~ 8% (to coating weight), penetrating agent JFC 3 ~ 5% (to coating weight), stir, be made into certain density dye liquor.
Described dyeing: dyeing temperature 50 ~ 60 DEG C, dyeing time 10 ~ 20min, bath raio 1:10 ~ 15.
Described fixation, after dyeing a period of time, directly adds adhesive and carries out fixation in dye bath.Adhesive therefor PB is esters of acrylic acid, binder dosage 5 ~ 10g/L, color fixing temperature 60 ~ 80 DEG C, fixation time 20 ~ 30min, pH value 4 ~ 5.Then lower the temperature, dewater, dry, bake.
The invention provides a kind of COTTON FABRIC fluorescent paint exhaust processes, by the cation modifying to fluorescent paint, improve the tinctorial yield of coating on fiber, make COTTON FABRIC without the need to carrying out cation modifying, can direct dyeing, shorten technological process, reach the effect of energy-saving and emission-reduction.
