Description

A kind of reactive dye colour discharge printing process
Technical field
The present invention relates to technical field of textile printing, and in particular to a kind of reactive dye colour discharge printing process.
Background technology
The discharge printing of reactive dye is applied in stamp extensively because having many advantages, such as that flower pattern is true to nature.Work as needs When printing fine floral designs on the fabric, such as using directly method completely is left white, floral designs will be distorted, and be sometimes The low-level methods of commercial permission.There is also be difficult to grasp to flower pattern to will produce double exposure again if not being left white side and generate for it The problem of third color, and these problems are exactly that discharge printing is avoidable.Discharge printing is also known as discharge printing, is that discharging agent is direct It is imprinted on colored fabric, the original pigment of coloured portions is made to change, to obtain the stamp of new floral designs.Discharge printing There are two types of, one is the background color colour killings that can make dyeing, form white decorative pattern, referred to as dawn.Another kind is can to make dyeing background color Discoloration, and it can be stained with new color, dyeing defect is formed, is known as pulling out print.Exquisite pattern is can print out using impression method is pulled out, deficiency is work Skill is more complicated.
The method that color pulls out has coating, intellectual circle, activity to pull out the several methods such as activity.
Coating pulls out reactive printing technique, for the reducing resistance of coating and adhesive, there is stringent selection.Moreover it applies Material is different with the imbibition degree of reducing agent, be easy to cause eyes circle or folded color phenomenon.Because of the addition of adhesive, for final The feel of article, some negative impacts of more or less generation, coating covers, of low grade, once falling off or fading The defect of shape can be revealed.
The printing technology of intellectual circle's dye discharging reactive dye, equally exists eyes circle and folded color phenomenon, and printing paste prepares work Skill is complicated, and cost is higher, chromatography is not complete, manages and demands strict technology, and quality is difficult to control, so being answered in actual production With few.
The color of reactive dye discharge reactive dye pulls out technique, utilizes the reactive dye of Vinyl-Sulfone Type and chloro-s-triazine activity Base carries out color to the different principle of the tolerance degree of alkali, using alkaline discharging agent and pulls out.Bottom is contaminated using the reactive dye of vinyl sulfone(RemzaolHuo Xingranliaohuoxingjituan) The reactive dye of color, a chloro-s-triazine make color and pull out slurry together as the dyestuff for entering dye, and alkaline discharging agent.Enter the activity of dye Dyestuff inevitably will produce the variation of coloured light under conditions of strong basicity, cause the color of product unstable, the matter of product Amount it is difficult to ensure that.
As Chinese patent application CN200810122358.6 disclose a kind of environment-friendly type coating discharge printing discharge slurry and its Discharge printing process, including coating discharge printing whitening pulp and coating discharge printing color pull out slurry, and coating discharge printing whitening pulp is Resistance to by 100 parts by weight pulls out composite thickening slurry, the softening agent of 1.5~2 parts by weight, the wetting and penetrating agent of 4~6 parts by weight and 3~7 The mixture that the discharging agent of parts by weight is uniformly mixed；Coating discharge printing color pull out slurry be by 100 parts by weight it is resistance to pull out it is compound Thickening slurry, the adhesive of 10~20 parts by weight, the softening agent of 1.5~2 parts by weight, the wetting and penetrating agent of 4~6 parts by weight, 3~7 The resistance to mixture for pulling out coating and being uniformly mixed of the discharging agent of parts by weight and 1~5 parts by weight.Such as Chinese patent application The pulling out property colour-spun yarns that CN200710036739.8 discloses a kind of discharge method of color textile fabric and its uses comprising as follows Step：Stock-dye：With can pull out reactive dye or resistance to pull out reducing dye and respectively dye fiber；Spinning：Choosing as needed It is matched with coloured fibre or brown stock, colour-spun yarns is beaten by DiplodiaFr. apudNont；Woven fabric：With fiber dyed yarn woven fabric；As needed Is carried out to color textile fabric, color pulls out or local dawn dawn.As Chinese patent application CN200810063371.9 discloses a kind of cotton Cloth reactive dye discharge printing process, i.e. activity pull out active artistic, contaminate background color to cotton using the dilute sulfone type CDR reactive dye of second, Mill base is made to cotton discharge printing using discharging agent and alkaline-resisting p-type reactive dye, is baked except color, flower color development is steamed, washes, dry It is dry, formula：Original paste：Discharging agent DK-TN20%+ urea 20~30%+ hydration is at 100%, whitening pulp：50~60%+ of original paste is helped Agent 1~10%+ water is pulled out, color pulls out slurry：MarcocionP dyestuffs+original paste 50~60%+ agent to help pull D-TN1~8%+ water /+sodium bicarbonate 2~4%.Foregoing invention is that stained clot-h product pull out processing by dawn or color, and color, which pulls out, contains pigmented finiss or dyestuff, process in slurry Complexity, coating coverage is bad, has an impact to the feel of fabric added with adhesive；Enter the dyestuff of dye under basic conditions, color It is unstable, variation is easy tod produce, final product quality is difficult to ensure.
Invention content
