Description
Technical field
The present invention relates to a kind of silk digit printing and do not have the slurry pre-treating method.
Background technology
Digital ink-jet printed as a kind of brand-new stamp mode, obtained development rapidly in recent years, represented the development trend in following printing in textiles field.The more traditional stamp of digit printing has 4 advantages: (1) has saved the plate-making process in traditional printing method, and printing and proofing speed is accelerated greatly, and the cost of drawing a design reduces.(2) be not subjected to the flower of style to enclose the restriction of size, tricks, to anthosin standard, levels are rich, printing quality is good, can be used for the stamp of grade textiles.(3) realize the customer demand of small lot, fast response, can produce superior, personalized stamp product.(4) pollution before and after the drop on demand ink jet, stamp seldom.The superiority of logarithmic code stamp has been reached common recognition in the dyeing industry, is referred to as " revolution of a textile printing technology ".Digit printing can be divided into active digit printing, Acid Techno stamp, disperse digit printing and coating digit printing etc. according to the difference of colouring agent.What the present invention relates to is active digit printing.Pre-treatment process is exactly the last slurry process of fabric under the present state of the art of active digit printing.Auxiliary agents such as thickener, alkaline agent, urea have mainly been comprised in the starching thickener.The purpose that adds thickener is for not imbibition of flower type in spray printing or the process of evaporating.It plays a part carrier in the stamp process, after fabric evaporates, thickener will be removed in washing step.No matter be natural paste or synthetic thickener, its existence not only can prolong the washing time, and energy consumption rises, and also can cause the wastewater treatment difficulty to increase.The effect of alkaline agent in the starching thickener is the set REACTIVE DYES.But owing to not alkaline-resisting dose of real silk, to selecting which kind of alkaline agent and concrete consumption most important, phenomenons such as the powerful decline of slim silk or color development instability appear easily on technology.Urea is a kind of common hygroscopic agent, helps the better color development of dyestuff, but is the biggest factor that causes the ammonia nitrogen index to increase.Therefore, though digit printing is compared traditional handicraft greater advantage is arranged, but still have very big progressive space.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned defective of the prior art, provides a kind of silk digit printing not have the slurry pre-treating method.
The present invention addresses the above problem the technical scheme that adopts: this silk digit printing does not have the slurry pre-treating method, may further comprise the steps:
Pad operation: prepare the padding liquid of being made up of softener, water repellent, sodium chloride and water in advance in groove, make the silk fabrics open width enter groove, the speed of a motor vehicle is at 20 meters/minute, and pick-up rate is controlled at 80%-100%;
Baking operation: the fabric after will padding is the tentering oven dry under the open width state, and bake out temperature is at 100 ℃-140 ℃, and the time of tentering oven dry is 2-3 minute;
Spray printing operation: adopt Numerical Control Printer to spend the type spray printing;
Evaporate operation: evaporate in cylinder evaporates equipment, evaporating temperature is 116 ℃-120 ℃, and the time of evaporating is 45 minutes-60 minutes;
Washing step;
Baking operation: the fabric after will padding is the tentering oven dry under the open width state, and bake out temperature is at 100 ℃-130 ℃, and the time of tentering oven dry is 2-3 minute.
The mass concentration of softener is the 0.2-1 grams per liter in the padding liquid of the present invention, and the mass concentration of water repellent is the 0.2-1 grams per liter, and the mass concentration of sodium chloride is the 20-40 grams per liter, and all the other are water, and the mass concentration ratio of softener and water repellent is 1:1.
The order of padding liquid preparation of the present invention is: water, softener, water repellent add earlier, and the back that stirs adds sodium chloride.
Washing step of the present invention adopts open width rinsing machine washing 2 times, and washing temperature is at 95 ℃-100 ℃, and 20 meters/minute of the speed of a motor vehicle were washed 2-3 minute at every turn.
Washing step of the present invention adopts the rope form rinsing machine, and washing temperature is at 95 ℃-100 ℃, soap boiling after 30 minutes again clear water wash.
Softener of the present invention belongs to the mixture of cationic softener or CATION and NON IONIC SOFTNER, comprises quaternary softener, fatty acid ester type softener, paraffin wax type softener.
Water repellent of the present invention belongs to the weak cation type, is the perfluoroalkyl acrylic copolymer.
The beneficial effect that the present invention has is: after digital spray printing adopts no slurry pre-treatment process, the fabric clear-cut of spray printing, the level solid is true to nature, bright in luster, pliability is good, compares the starching pre-treatment process, and spray printing product quality integral body is obviously promoted, solved that the rich and gaudy degree of Dry Sack that often occurs in the spray printing process in the past contradicts with fineness and slim fabric owing to destarch not to the utmost, feel problem such as harden.In addition, owing to there is not thickener to exist, therefore alleviated the washing burden greatly in the no slurry pre-treatment process; Do not have alkaline agent to exist, therefore do not have fabric yellowing, powerful degradation problem down; Do not have urea to exist, therefore do not have the too high problem of ammonia nitrogen index.Pre-treating method provided by the invention is fit to large-scale production, and technological process is succinctly easy to operate, constant product quality.
