Abstract

The invention provides a circulating dyeing process, which adopts a routine process for dyeing. The dyeing process adopts a circulating dyeing mode, namely after first-jar dyeing is finished, the dye solution in the jar is retained, the dye, auxiliary agents and water are supplemented, then second-jar dyeing is carried out, and circulating and repeated dyeing is carried out until the batch of products are dyed. The circulating dyeing process provided by the invention has the beneficial effects that the process is simple, the operation is simple and convenient, the working time is shortened and the productivity is greatly increased; at the same time, the consumptions of the dye, the auxiliary agents and water are reduced; repeated heating is not needed, thus the steam consumption is greatly lowered, and the power consumption is significantly reduced; and an energy-saving and emission-reducing effect is realized, and the production cost is greatly lowered.

Description

A kind of dyeing cycle technology

(1) technical field

The present invention relates to a kind of dyeing of field of textiles, particularly relate to a kind of dyeing cycle technology.

(2) background technology

As everyone knows, dope dyeing is to pollute one of more serious industry, wool, acrylic fibres dyeing especially water, with the rich and influential family of dyestuff, the waste water of its generation and the discharging of noxious material will inevitably cause great destruction to environment.Advocate energy-saving and emission-reduction today, how to reduce the consumption that water, electricity, vapour can the energy, reducing the discharging of refuse simultaneously, becoming the common difficulty of dope dyeing industry.

(3) summary of the invention

The present invention provides a kind of dyeing cycle technology in view of above-mentioned purpose.

Technical scheme of the present invention is to realize like this.

The dyeing cycle technology of this programme adopts common process dyeing.This dyeing adopts dyeing cycle mode, that is: after first cylinder dyeed out cylinder, dye liquor kept in the cylinder, append dyestuff, auxiliary agent, water after, carry out the dyeing of second cylinder again, circulating to redye to dyeing product by the gross with this finishes.

With the used dyestuff of first cylinder, auxiliary agent, water is radix, and the consumption and the steam consumption that append dyestuff, auxiliary agent, water are:

The second cylinder usefulness, dyestuff: 95%;

Acetic acid: 90%;

The silicon breast: 90%;

Water consumption: 75%;

The vapour consumption: 60%;

Be circulated to last cylinder with this.

The invention has the beneficial effects as follows: technology is simple, and is easy and simple to handle, shortens man-hour, can increase substantially productivity ratio.Simultaneously, the consumption of dyestuff, auxiliary agent, water reduces.Because of needn't be again, repeat to heat up, steam consumption also significantly reduces, power consumption obviously reduces.Meet energy-saving and emission-reduction, can significantly reduce production costs.

(4) description of drawings

Accompanying drawing is the process chart of this programme embodiment.

(5), the specific embodiment

Below in conjunction with embodiment the present invention is described further.

Embodiment:

One, raw material:

The conventional acrylic fibers of 3D: 100%, dye black.

Quantity: 16600Kg.

Two, technological process

The pinecone, bar dye, after backwashing, oven dry, combing.

Three, dyeing

Acrylic fibers bar 100Kg one cylinder:

Dye out behind the cylinder, dye liquor keeps in the cylinder, appends dyestuff, behind the auxiliary agent, redyes second cylinder again, redyes to black with this number to finish.

Append dyestuff, the consumption of auxiliary agent is:

The second cylinder usefulness, dyestuff: 95%

Acetic acid: 90%

The silicon breast: 90%

Water consumption: 75%

The vapour consumption: 60%.

Four, dyeing cost accounting

Project cylinder number	First cylinder	Second cylinder
			Dyestuff	200 yuan/100Kg	190 yuan/100Kg
Acetic acid	15 yuan/100Kg	13.5 unit/100Kg
			The silicon breast	42 yuan/100Kg	37.8 unit/100Kg
Water	16 yuan/100Kg	12 yuan/100Kg
			Vapour	170 yuan/100Kg	102 yuan/100Kg
Amount to	443 yuan	355.3 unit

Traditional dyeing technology dyeing expense per ton: 443*10=4430 unit/ton.

Dyeing cycle new technology dyeing expense per ton: 443+355.3*9=3640.7 unit/ton.

Dyeing cycle new technology energy savings, dyestuff, the auxiliary agent expense amounts to: 789.3 yuan/ton.

This batch of output is 16600Kg, cuts down expenses 13102.38 yuan altogether.

Five, the problem that should note

Second cylinder appends dyestuff, auxiliary agent, and different according to dye level, accurate Calculation is appended the shallow partially control of consumption.

When temperature rose to insulation, dye level was surveyed in sampling, supplies dyestuff when error is arranged, and auxiliary agent guarantees out cylinder dye level uniformity, the no color differnece phenomenon.

Claims (2)

1. a dyeing cycle technology adopts common process dyeing, and it is characterized in that: this dyeing adopts the dyeing cycle mode; That is: first cylinder dyes out behind the cylinder, and dye liquor keeps in the cylinder, append dyestuff, auxiliary agent, water after; Carry out second cylinder dyeing again, circulating to redye to dyeing product by the gross with this finishes.

2. dyeing cycle technology according to claim 1 is characterized in that: with the used dyestuff of first cylinder, auxiliary agent, water is radix, and the consumption and the steam consumption that append dyestuff, auxiliary agent, water are:

The second cylinder usefulness, dyestuff: 95%;

Acetic acid: 90%;

The silicon breast: 90%;

Water consumption: 75%;

The vapour consumption: 60%;

Be circulated to last cylinder with this.
