Abstract
The invention discloses a process for dyeing high-density nylon with a low bath ratio by using a jig dyeing manner. The process for dyeing high-density nylon with the low bath ratio by using the jig dyeing manner comprises the following steps: padding a desizing solution, then piling the desizing solution for a certain time under the normal temperature, then continuously washing with water by using a long padder, completely removing impurities comprising size of a gray fabric and an oiling agent by using the effects of emulsifying, dispersing, solubilizing, degrading and washing so as to improve the dyeing quality. The process is free of high-temperature treatment, so that the coal consumption can be saved; meanwhile, due to the adoption of the padding process solution, a large amount of clean water is saved; due to semi-continuous production, the production efficiency is improved; the processed gray fabric is weak in alkalinity and is dyed under the alkaline condition, the dyeing time and the dyeing rate of a dye are reduced, the dyeing uniformity is ensured; the dyeing defect rate is greatly reduced; the dyeing quality is improved; as the desizing process before dyeing is omitted in the alkaline dyeing process, the processes of desizing and dyeing are completed at a time, so that the costs of energy, water treatment and the labor are also greatly reduced; and the production cost is reduced. The process for dyeing high-density nylon with the low bath ratio by using the jig dyeing manner is combined with the advanced technology; the requirements of the current market are met; a great failure of the printing and drying industry is solved; simultaneously, a great contribution is made to the textile; the process for dyeing high-density nylon with the low bath ratio by using the jig dyeing manner has a good market development prospect.
Description
Technical field
The present invention relates to a kind of dyeing nylon technique, specifically the low bath raio dye gigging of a kind of highly dense nylon dyeing.
Background technology
Nylon product is in the time weaving, and for preventing balling-up, broken yarn all can be given Yarn oiling, starching before weaving, and increases the cohesive force of nylon yarn by starching, brute force and ABRASION RESISTANCE, thus prevent from weaving middle yarn fluffing, reduce broken end, improve and weaved quality.The faults such as the finish that these add and slurry must be removed completely before dyeing processing, otherwise can affect dyeing quality, produce uneven dyeing or color dot, look flower.Traditional handicraft dyeing pre-treatment is all in staining jar, to move back refining before dyeing, adds a certain amount of caustic soda to be warming up to high temperature of 120 DEG C and processes approximately 30 minutes, then cooling washing.Slurry after this PROCESS FOR TREATMENT on grey cloth and finish can be removed substantially, Color ideal.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 simultaneously, batch production, production efficiency is lower.
The ultra-fine dyeing process of highly dense nylon of present stage is still mainly taking overflow machine as main, and high bath raio overflow machine needs more substantial dying auxiliary agent, water, electricity, vapour, and not only energy consumption is large, production cost is high, and overflow rope dyeing also can produce wrinkle and print.And common dye jigger is due to when dyeing dye liquor static scrolling of dying cloth in dye vat, dyestuff in dye liquor can not uniform distribution in dye liquor due to the static of dye liquor, cause the cloth of dyeing to occur aberration, look flower waits dyeing substandard products, meanwhile, the mode of heating in common dyeing by jigger city is to be led directly to into dye liquor by steam pipe, the dye aberration of the inhomogeneous generation of temperature control meeting, therefore, common dye gigging is generally used for the clothes lining dyeing processing not high to quality requirements.This technique is on former dye jigger basis, to have carried out technological transformation, install a set of heat exchanger additional by leading directly to into the steam pipe of dye liquor, computer control in dyeing course, dye liquor in dye vat is due in recurrent state, temperature is even, avoid the unbalanced dyeing look flower causing of temperature, improved dyeing quality.Therefore, substituted the overflow dyeing of highly energy-consuming completely by low bath raio dye gigging dyeing through the ultra-fine dyeing of the highly dense nylon of this project technological innovation.
Summary of the invention
The object of the present invention is to provide the low bath raio dye gigging of a kind of highly dense nylon dyeing, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
The low bath raio dye gigging of a kind of highly dense nylon dyeing, comprises the following steps:
(1) pad desizing liquid by existing nylon fabrics by cold-rolling mill, fabric clot is at normal temperatures put into cold-rolling mill and pile to 10-15 hours; After the cold dome time arrives, then wash through the long vehicle rinsing machine that contains 10 rinsing bowls;
(2) nylon fabrics after washing is carried out to presetting technology at 130-150 DEG C;
(3) nylon fabrics after pre-setting is entered to water, keep temperature 28-32 DEG C, move and add dyestuff after 20-30 minute, add caustic soda and regulate pH to 5.5-6.5, operation 30-40 minute, is 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 to 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 to ventilating and cooling place and dries, 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 further scheme of the present invention: in step (4), temperature optimum value 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 the certain hour of banking up at normal temperatures, after through the washing of continuous long vehicle, by emulsification, disperse, solubilising, degraded, washing texts are thoroughly removed the slurry of grey cloth, and the impurity such as finish, improve dyeing quality, this technique is without high-temperature process, can save consumption coal, simultaneously because being to pad process liquor to have saved a large amount of clean water, semi-continuous production has improved production efficiency; After processing, grey cloth is alkalescent simultaneously, dyes by under alkali condition, has delayed to dye time and dyeing rate on dyestuff, has ensured the even of dyeing, and look flower rate reduces greatly, has improved dyeing quality.Saved destarch operation before dyeing because of basic dyeing technique, destarch dyeing once completes, and has also greatly lowered the energy, water treatment, artificial etc. consumption, reduces production costs.This project has merged advanced technology and has met again the demand of Vehicles Collected from Market, solves dyeing one major break down, and for weaving also makes a great contribution, the developing target market prospect of this project is good simultaneously.
