Description
Technical field
The utility model relates to dyeing and finishing machinery technical field, and the dye liquor being specifically related to the extremely low bath raio yarn dyeing machine of 1:2 exchanges and distribution system.
Background technology
Textile industry is the important industry of Chinese national economy, for a long time, textile industry be national economy development, solve that the people wear the clothes, major contribution has been made in the aspect such as foreign exchange earning, and in this industry, have consequence undoubtedly as the dyeing and finishing industry connecting bridge.Dyeing and finishing industry is textiles deep processing, fine finishining and the key putting forward added value, is textile fabric, raw yarn, embryo cloth is processed into tie between the final products entering consumer goods market, play the important function promoting product and jointly develop.
Bath raio is an important index in dyeing course, and the size of bath raio directly reflects the key index of the energy consumption height such as dyeing installation water, electricity, steam and pollutant emission height.The dye liquor of preparation and the mass ratio of pollutant when bath raio refers to and contaminates or exhaust dye dyeing.Density often dye liquor in production application is used as 1 and is processed.Bath raio has dividing, if 1:20,1:30 are large bath raio of size; 1:3,1:5 are short liquor ratio.Bath raio, also known as liquor ratio, refers to the ratio of yarn and dye liquor weight.As textiles 100 kilograms dye liquor 1000 kilograms, then bath raio is 1:10.The shortcoming of tradition equipment for dyeing and finishing is that bath raio is large, power consumption large, many with dye addictive, the process time is long.During actual production, spindle is under drenched water saturation state, and dye liquor soaks half whole creel.Adopt the equipment for dyeing and finishing of pole low bath ratio dyeing technology, its advantage mainly contains:
(1) dyestuff is saved.In dyeing course, the concentration of dyestuff in different bath raio of same amount is different, and dye-uptake when it reaches dyeing equilibrium is also different, dyestuff need to reach in dye liquor minimum on contaminate concentration.When carrying out short liquor dyeing when certain consumption dyestuff, in its dye liquor, the relative concentration of dyestuff is larger, dye strength on fabric fibre rises with the increase of dye strength in dye liquor, and dyestuff remaining in dye liquor is due to its residual total amount also corresponding decline of the minimizing of bath raio, decrease the discharge capacity of dyestuff in discarded dye liquor.Otherwise bath raio is large, and the dye strength in dye liquor is relatively low, and dye strength when fabric fibre contaminates is also lower, thus adds the discharge capacity of dyestuff in spent dye liquor.Therefore, the size of bath raio directly can affect exhaustion rate and the degree of fixation of dyestuff, particularly for conventional REACTIVE DYES.The size of bath raio directly can affect auxiliary agent, electrolytical consumption.When carrying out short liquor dyeing, not only fabric obtains color depth, decreases the consumption of color additive simultaneously, decreases the discharge capacity of sewage.
(2) reproducibility is good.When carrying out short liquor dyeing, the change of bath raio is relatively little, though dyestuff is different to the interdependence of bath raio, because bath raio is little, the change of fabric dye-uptake is little, and aberration is generally within acceptable scope, and namely the reappearance of short liquor dyeing is relatively better.
(3) uniform dyeing property is good.During dyeing, the quality of level-dyeing property of fabric depends primarily on the cycle frequency of dye liquor.During dyeing, bath raio reduces, and the cycle-index of dye liquor just increases.The cycle frequency of dye liquor is larger, and diffusion and the upper dye chance of dyestuff are just many, just can improve the situation of local uneven dyeing.
(4) short liquor dyeing water saving, energy-conservation.During dyeing, the consumption of water, electricity, steam is all relevant with bath raio, and the little then energy consumption of bath raio is low.Many provinces wash water system that short liquor dyeing is additional and multifunctional intellectual water wash system, have very significant water-saving result.Short liquor dyeing technology has significant technical advantage in textile dyeing, and heat transfer rate is high, and master cylinder water level is full of with drain time short, water saving, energy-conservation, greatly shorten dyeing cycle, increase output.
Short liquor dyeing is good level-dyeing property not only, saves the consumption of dyestuff, auxiliary agent, ensure that the reappearance of dyeing, and more embodies feature that is efficient, energy saving standard.Therefore, short liquor dyeing is the main development direction of dyeing and finishing technique.
