Description

Colored textile high temperature, high-pressure injection dyeing and equipment

Technical field:

The invention belongs to the printing technology field, particularly a kind of colored textile changes the improvement of dyeing and equipment.

Background technology:

At present, the dyeing again of all clothes and textiles all belongs to water dyeing, is about in the dye liquor that textiles is placed on certain bath raio evenly paintedly, and its deficiency is: 1, energy waste is bigger; 2, dye loss is bigger because bath raio is bigger, reduced between dyestuff and the fiber gravitation with combine chance, having greatly, dyestuff becomes loose colour and slatterns; 3, be prone to pattern and pleating, owing to require to have between water and fabric relative motion avoiding pattern, as stop motion in short-term appears or movement velocity inhomogeneous, pattern will appear, the water method of dying is that clothing is soaked in dye liquor, is easy to make the pleating or distortion of clothing behind the high temperature; 4, after printing and dyeing were finished, the discharging meeting of dye liquor caused serious pollution to environment; 5, can not local dyeing and fixation to clothing.

Summary of the invention:

The purpose of this invention is to provide a kind of can save in a large number the energy, dyestuff, pollution-free, dye, change colour and return new effective high temperature, high-pressure injection dyeing and equipment.

Processes and apparatus of the present invention is as follows:

Its technology is:

1, textiles is divided into shallow, in, dark three classes;

2, textiles is weighed the dyestuff content of reference colour when calculating textiles and not fading;

A, light textile dye content are 0.2 one 0.6% of textiles weight

B, middle look textile dye content are the 0.6-1.5% of textiles weight

C, dark textile dye content are the 1.5-2.5% of textiles weight

3, calculate the dyestuff weight that textiles has taken off color, use the colour atla comparison method, the textiles position of fading is compared mutually with the position of not fading, calculate and take off color percentage: x% approximately, and then can calculate the dyestuff weight of having taken off color:

Fugitive dye weight: reference colour dyestuff weight X%:

4, according to fading what principle, can get shallow, in, the dyestuff of dark corresponding weight:

5, the consumption of spray-painting auxiliary agent is 2-10 times that water dyes the positive usual amounts of method;

6, the temperature during spray-painting is 120 ℃ one 200 ℃, and steaming and dying color fixing temperature is 200 ℃ one 280 ℃; The spray-painting time finished in 1 one 5 minutes, steamed and dyed the time at 20-60 minute, and the spray-painting bath raio is 8 one 12 times of water bath raio;

7, according to 4 get shallow, in, the dyestuff of dark corresponding weight, get various auxiliary dosages according to 5, adjust bath raio according to 6, dyestuff and auxiliary agent are used 20-40 ℃ water-soluble respectively, fully stir evenly, cover tight dye tank loam cake heating dyestuff is heated to 120 ℃ one 200 ℃, when in-cylinder pressure reaches the 0.1-0.2 MPa, open air-pump inflating, when treating that in-cylinder pressure reaches the 0.14-0.5 MPa, each position of textiles is sprayed with spray gun, with the dyestuff in the dye tank under high-temperature high-pressure state, be sprayed onto equably on the textiles, be sprayed onto saturated till, be advisable not drip dye liquor; Be put into to steam in the dye vat and steam the bath fixation being sprayed onto saturated textiles; Steam in the dye vat and put into 1 one 5 kilograms in clear water, heater heats steaming dye vat, and the tight dye vat loam cake that steams of lid makes cylinder temperature reach 200 ℃ one 280 ℃, when steam pressure is the 0.1-0.2 MPa, stops heating, is incubated 10-30 minute; Treat that in-cylinder pressure is kept to normal pressure, open and steam dye vat, textiles taken out tremble cold, washing, put in order and press, finalize the design.

Its equipment is:

Air pump is communicated with the dye tank of sealing by air inlet pipe, and the spray-painting rifle is communicated with dye tank by spray-painting material pipe, and dye tank be for can bearing the closed container of 0.3 MPa high pressure, in dye tank or the bottom be provided with heater, in steaming dye vat or the bottom be provided with heater.

The invention has the beneficial effects as follows: can save the energy, dyestuff in a large number, thereby greatly reduce the printing and dyeing cost; Shortened dyeing course and time, need just can dye equal textiles in about 40 minutes originally, and existing only need can achieve the goal in about 10 minutes; Because textiles is the printing and dyeing that realize under loose condition (of surface), the phenomenon that long-time high temperature goes out pleat can not occur, can not be out of shape; And can realize local dyeing and resisdye; Dyestuff utilizes high, and is pollution-free substantially.
