Abstract
The invention discloses a low-bath-ratio jig dyeing technology for high-density nylon. The technology comprises the steps that padding is performed on the high-density nylon through desizing liquid, and then the high-density nylon is piled up for a certain time at normal temperature; continuous water washing is performed, impurities such as a sizing agent and an oiling agent on a grey cloth are thoroughly removed through the effects of emulsifying, dispersing, solubilizing, degrading, washing and the like, and the dyeing quality is improved. According to the technology, high temperature treatment is not performed, and therefore consumed coal can be saved; due to the fact that a padding technology is adopted, a large amount of clean water is saved, and the production efficiency is improved through semi-continuous production; meanwhile, the treated grey cloth is slightly alkaline, that is, dyeing is performed under the alkaline condition, therefore, the dyeing time of dye is prolonged, the dyeing rate of the dye is decreased, the dyeing uniformity is guaranteed, the dyeing defect rate is greatly decreased, and the dyeing quality is improved; due to the fact that a desizing procedure before dyeing is omitted in the alkaline dyeing technology, desizing and dyeing are completed in one time, therefore, consumption of energy sources, water treatment and labor is greatly reduced, and the production cost is lowered. The technology integrates an advanced technique, meets the requirements of current markets, overcomes a big defect in the printing and dyeing industry, makes a great contribution to spinning and is good in the development market prospect.
Description
Technical field
The present invention relates to a kind of dyeing nylon technique, specifically a kind of highly dense nylon low bath raio dye gigging dyeing.
Background technology
Nylon product is when weaving, and for preventing balling-up, broken yarn, all can give Yarn oiling, starching before weaving, and is increased the cohesive force of nylon yarn by starching, powerful and ABRASION RESISTANCE, thus prevents from weaving the fluffing of middle yarn, reduces broken end, improves and weave quality.The faults such as these finishes added and slurry must be removed completely before Colour Difference, otherwise can affect dyeing quality, produce uneven dyeing or color dot, look flower.Traditional handicraft dyeing pre-treatment is all carry out moving back refining before dyeing in staining jar, adds a certain amount of caustic soda and is warming up to high temperature of 120 DEG C process about 30 minutes, then washing of lowering the temperature.Slurry after this PROCESS FOR TREATMENT on grey cloth and finish can be removed substantially, and Color is desirable.But this technical process meeting water consumption, power consumption, consumption vapour.Energy-output ratio is high, and production cost is high.Take 40% of whole dyeing cost.Should this technique be that a cylinder cylinder carries out in dye vat, batch production, production efficiency be lower simultaneously.
The ultra-fine dyeing process of present stage highly dense nylon is still main based on overflow machine, and high bath raio overflow machine needs more substantial dyeization auxiliary agent, water, electricity, vapour, and not only energy consumption is large, production cost is high, and overflow rope dyeing also can produce wrinkle print.And common dye jigger is due to dye liquor static scrolling of dying cloth in dye vat during dyeing, dyestuff in dye liquor can not uniform distribution in dye liquor due to the static of dye liquor, the cloth dyeed is caused to occur aberration, look flower waits dyeing substandard products, meanwhile, the mode of heating in common dyeing by jigger city leads directly to into dye liquor by steam pipe, and temperature controls the dye aberration of the uneven generation of meeting, therefore, common dye gigging is generally used for the clothes lining Colour Difference not high to quality requirements.This technique has carried out technological transformation on former dye jigger basis, a set of heat exchanger is installed additional into the steam pipe of dye liquor by leading directly to, conputer controlled in dyeing course, dye liquor in dye vat is owing to being in recurrent state, homogeneous temperature, avoid the unbalanced dyeing look flower caused of temperature, improve dyeing quality.Therefore, pass through this Project Technical and reform the ultra-fine dyeing of highly dense nylon be instead of highly energy-consuming completely overflow dyeing by low bath raio dye gigging dyeing.
Summary of the invention
The object of the present invention is to provide a kind of highly dense nylon low bath raio dye gigging dyeing, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of highly dense nylon low bath raio dye gigging dyeing, comprises the following steps:
(1) pad desizing liquid by existing for nylon fabrics by cold-rolling mill, fabric clot is at normal temperatures put into cold-rolling mill heap to 10-15 hours; After the cold dome time arrives, then wash through the long vehicle rinsing machine containing 10 rinsing bowls;
(2) nylon fabrics after washing is carried out presetting technology at 130-150 DEG C;
(3) nylon fabrics after pre-setting is entered water, keep temperature 28-32 DEG C, run and add dyestuff after 20-30 minute, add caustic soda and regulate pH to 5.5-6.5, run 30-40 minute, be warming up to 95 DEG C with 5 DEG C/min, insulation operation 25 minutes, is then down to room temperature and takes out nylon fabrics washing;
(4) nylon fabrics after washing in step (3) is carried out fixation, fixation bath raio is 1:2-1:2.5, adds 4-5g/L color-fixing agent, is warming up to 90-120 DEG C, and insulation 35-45 minute, takes out washing;
(5) nylon fabrics after washing is positioned over ventilating and cooling place to dry, temperature is 25-35 DEG C.
As the further scheme of the present invention: described desizing liquid is made up of 5-7g/L caustic soda, 2-3g/L quickly penetrating agent and 4-5g/L alkaliproof refining agent.
As the present invention's further scheme: in step (4), temperature optima is 115 DEG C, temperature retention time 40 minutes.
Compared with prior art, the invention has the beneficial effects as follows: by padding desizing liquid, then certain hour of banking up at normal temperatures, after wash through continuous long vehicle, by emulsification, dispersion, solubilising, the effects such as degraded, washing thoroughly remove the slurry of grey cloth, the impurity such as finish, improve dyeing quality, this technique is without high-temperature process, can save consumption coal, simultaneously because being that padding process liquid saves a large amount of clean water, semi-continuous production improves production efficiency; After process, grey cloth is alkalescent simultaneously, namely dyes by under alkali condition, has delayed dye time and dyeing rate on dyestuff, ensure that the even of dyeing, and look flower rate reduces greatly, improves dyeing quality.Because basic dyeing technique eliminates destarch operation before dyeing, destarch dyeing once completes, and also greatly reduces the energy, water treatment, artificial etc. consumption, reduces production cost.This project has merged the demand that advanced technology meets again Vehicles Collected from Market, solves dyeing one major break down, and simultaneously for weaving also makes a great contribution, the developing target market prospect of this project is good.
