Abstract

The invention discloses a method for controlling a dyeing process adopting a rope-like cloth dyeing machine driven by a conveying belt. Cycle indexes of cloth in a dye vat are used as control units for controlling a dyeing program (dyeing program for short), namely dosing speed, heating and cooling rate, heat preservation time length, washing time length and the like in the dyeing process, the overall dyeing process takes the cycle indexes of cloth as control units, and a computer or a program controller controls the dyeing process.

Description

There is the Colour Difference course control method for use of the rope form piece dyeing machine that conveyer belt drives

Technical field

The present invention relates to colouring processing method, espespecially a kind of Colour Difference course control method for use with the rope form piece dyeing machine that conveyer belt drives.

Background technology

Fig. 1 is the piece dyeing circulation schematic diagram that rope form textile dyeing machinery is commonly used in display.Its principle is that dye liquor F pressurizes via heat exchanger C(intensification or cooling via pumping D2) enter nozzle A4, produce and spray or overflow current strength, return the long-pending cloth groove A1 of textile dyeing machinery A, cloth B then utilizes cloth-guiding wheel A3 to drive (or without the need to cloth-guiding wheel) to enter nozzle A4, by injection or the overflow strength drive cloth B circulation of nozzle A4, dyestuff and auxiliary agent then to be pressurizeed via pumping D1 by auxiliary agent bucket E and inject the dye liquor closed circuit of textile dyeing machinery A, dye liquor F and cloth B is in the circulating cycle via making dyestuff be absorbed to reach refining by cloth in heat exchanger C heating and thermal insulation and temperature-fall period, dyeing, the Colour Difference such as fixation and washing effect, and dyeing the uniformity (equalization), then depend on the cycle-index number of cloth in dyeing course, that is cloth B between nozzle A4 and Dyeing pipe A2 with the number of dye liquor reciprocation number of times.Cycle-index the more represents that reciprocation is the more secondary, and therefore dye more even, washing degree and fastness are also same simultaneously.

Coordinate the typical process programme diagram commonly using rope form textile dyeing machinery consulting Fig. 2, no matter known textile dyeing machinery scientific principle or practice are all control unit (denominator), to carry out the Colour Difference processing procedure of dosing → intensification → insulation → intensification → insulation → cooling → washing → dosing → intensification → insulation → cooling → hot water wash to cloth with time; And its controlling party rule utilizes the controller such as computer or program control (PLC) to control.

The staining method that cause commonly uses rope form textile dyeing machinery is control unit with time, no matter therefore the actual amount of dying cloth length, dyeing course all needs same time, but during actual dyeing, its amount of dying cloth is because of weight or cloth thickness difference, that is the every cylinder of textile dyeing machinery, cloth length often in pipe or every groove neither with, though therefore fabric is identical, if but all adopt identical dyeing time, then not only lose time, and cloth is in whole dyeing course, due to every cylinder or often the actual stained clot-h amount (length) of pipe is different and make cloth actual cycle number of times also different, though therefore cause dyeing time identical but to execute dye degree not identical, on the contrary produce pipe difference or cylinder poor, fastness is inconsistent, the problems such as repeatability is not good, cause and need redye and make the quality of production and efficiency not good, waste energy in a large number and cost of labor and environmental pollution, this reproducibility problems be dye cloth for a long time factory face and be difficult to the problem that overcomes.

Summary of the invention

Object of the present invention, be the Colour Difference mode solving known rope form textile dyeing machinery, be all control unit with time, no matter so that the actual amount of the dying cloth length of identical fabric, all carry out Colour Difference process with same time, though cause dyeing time identical but to execute dye degree not identical, the problem such as produce pipe difference on the contrary or cylinder is poor, fastness is inconsistent, repeatability is not good, lose time.

The present invention is for solving this problem, it is the control mode changing traditional textile dyeing machinery, change with cloth cycle-index as controlling unit (denominator), also the abscissa " time " by the curve map shown in Fig. 2 changes into " cycle-index ", though like this then cloth actual enter cloth amount length number, all control dyeing course with cloth cycle-index, then when cloth is longer, the required bulk dyeing time is longer, and when cloth is shorter, then dyeing time can shorten relatively; Therefore, the cycle-index of cloth each dye pipe or every batch of every cylinder in whole dyeing course of identical fabric is all identical, then execute dye degree, washing degree etc. all identical, therefore can guarantee that zero pipe is poor or zero cylinder is poor, fastness is consistent, repeatability a hundred per cent, significantly improve the quality of production and efficiency, and significantly reduction production cost and carbon reduction promote environmental protection.

For reaching above-mentioned purpose, solution of the present invention is:

A kind of Colour Difference course control method for use with the rope form piece dyeing machine that conveyer belt drives, in the Colour Difference process of cloth, for time length or the speed speed of the processes such as dosing, intensification, insulation, cooling, washing, utilize the cycle-index of cloth in textile dyeing machinery as control unit, so as to carrying out Colour Difference to cloth.

Technological means of the present invention, be provided with the leftover of bolt of cloth and circulation timei and cycle-index and examine and calculate device having the suitable place of body of rope form piece dyeing machine that conveyer belt drives, drive with conveyer belt because cloth moves from rear forward end, cloth circulation rate is then synchronous with conveyer belt, though therefore cloth often returns adjustable circulation timei, but after setting, be constant speed, regularly, namely the present invention utilizes the characteristic of this constant speed, through computer or program controller (PLC), with the control unit of cloth cycle-index as dye journey, can guarantee to shorten dyeing time as previously mentioned, poor without pipe, poor without cylinder, fastness is consistent, repeatability absolutely, and can therefore improve the quality of products, enhance productivity, reduce production cost, carbon reduction, promote environmental protection.

Advantage of the present invention comprises:

One, bulk dyeing process time shortens because the amount of dying cloth length reduces.

No matter the length number of the two actual amounts of dying cloth, cloth cycle-index is all identical, executes dye degree identical, therefore dyeing repeatability is absolutely, cylinder poor without pipe poor with fastness the problem such as poor.

No matter the length of the three actual amounts of dying cloth, because cycle-index is all identical, cloth cover contacts with textile dyeing machinery (friction and stretching), and number of times is identical, therefore fabric quality is consistent.

Detailed description of the invention

In order to explain technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.

As shown in Figure 4, the present invention is provided with the leftover of bolt of cloth and circulation timei and cycle-index and examines and calculate device 1 having the suitable place of body of rope form piece dyeing machine that conveyer belt drives, drive with conveyer belt because cloth moves from rear forward end, cloth circulation rate is then synchronous with conveyer belt, though therefore cloth often returns adjustable circulation timei, but after setting, be constant speed, regularly, namely the present invention utilizes the characteristic of this constant speed, through computer or program controller (PLC), with the control unit of cloth cycle-index as dye journey, can guarantee to shorten dyeing time as previously mentioned, poor without pipe, poor without cylinder, fastness is consistent, repeatability absolutely, and can therefore improve the quality of products, enhance productivity, reduce production cost, carbon reduction, promote environmental protection.

Fig. 3 is the curve map that display the present invention has the Colour Difference process of the rope form piece dyeing machine that conveyer belt drives, after changing the abscissa in the curve map of the rope form textile dyeing machinery Colour Difference process shown in Fig. 2 into " cycle-index " by known " time ", Colour Difference process is controlled through computer or program controller, that is the process of dosing → intensification → insulation → intensification → insulation → cooling → washing → dosing → intensification → insulation → cooling → hot water wash in Colour Difference process is all control unit with cycle-index, in other words, the every circulation primary of cloth adds how many medicines, heat up or the cooling several years, insulation and the time length etc. of washing, be all control unit with cycle-index, so can because of the difference of actual cloth amount length the time of bulk dyeing process also not identical, the such as textile dyeing machinery of identical fabric 500kg cylinder, can the comparatively amount of dying cloth 500kg time shorten half during the actual amount of dying cloth 250kg, and its execute dye degree, Color is identical, repeatability is consistent, historical facts or anecdotes is a revolutionary innovation.

From the above, the actual Color of rope form piece dyeing machine driven because having conveyer belt mainly directly depends on that cloth cycle-index number and non-temporal length (that is become absolute relation with cycle-index, and be relativeness with the time), be thus the cloth speed of often pipe or every cylinder of textile dyeing machinery is identical time, if the time is also identical, then the actual amount of the dying cloth length cycle-index in elder's dyeing course that heals is fewer, otherwise then cycle-index is more for the amount of dying cloth length shorter one.Though therefore the time is identical but to execute dye degree different, Color is also different, cause the problems such as pipe is poor, cylinder is poor, fastness is different, repeatability is inconsistent, therefore identical fabric is for reaching identical Color, no matter the then amount of dying cloth length, cycle-index should be identical, that is cloth length shorter one, time can shorten relatively, so not only can shorten the whole dyeing course time, no matter simultaneously because of cloth length, cycle-index is all identical, execute dye degree identical, the absolutely repeatability of dyeing can be guaranteed, and unlikely generation pipe difference or cylinder is poor need redye with fastness difference.

As described above is only to explain preferred embodiment of the present invention; not attempt does any pro forma restriction to the present invention according to this; there is any modification for the present invention or the change done under identical creation spirit therefore all, all must be included in the category that the invention is intended to protect.
