Description
Technical Field
The invention relates to the field of textile printing and dyeing machinery, in particular to a nozzle system of an overflow jet dyeing machine, a cloth guiding and arranging device and a fabric running method.
Background
The traditional long-tube structure overflow jet dyeing machine in the printing and dyeing industry is gradually replaced by a low-bath-ratio overflow jet dyeing machine with a tank structure in recent years due to the large bath ratio, the large using amount of water, heating steam and dyeing materials and the high sewage treatment cost, and the development requirement of energy conservation, emission reduction and environmental protection of the industry is contradicted. The machine type is characterized in that liquid flow sprayed by a nozzle is repeatedly and circularly exchanged with fabric to complete dyeing processing of the fabric, the repeated and circular motion of the fabric is driven by the aid of the liquid flow sprayed by the nozzle as main power, the fabric can be separated from liquid in a cloth tank without being completely immersed in dye liquor, water consumption meets the nozzle spraying amount, the fabric moisture absorption liquid amount and the dye dissolving amount, the water consumption is less than that of a long-tube type jet dyeing machine, the dyeing bath ratio is reduced, water and steam are saved, the dye is saved, energy is saved, consumption is reduced remarkably, and the machine type is favored by printing and dyeing enterprises.
However, when the fabric in rope form is dyed and processed by the low bath ratio overflow jet dyeing machine, the fabric is driven to run in the warp direction by means of the water flow force sprayed by the nozzle, so that the fabric has larger warp running tension, the fabric passes through the nozzle and then runs in the rope form with the warp yarn tension being not expanded, and the running states of the fabric in the rope form with the larger warp yarn tension and the rope form with the weft yarn bending stress are important factors influencing the physical and chemical reaction of the fabric under the process conditions of temperature, humidity, chemical additives and the like to determine the final cloth surface quality after dyeing processing is completed, such as the shrinkage, the gram weight, creases, flatness and the like of a final cloth surface finished product, particularly, some knitted fabrics which are light, thin, high-density, high-elasticity, easy to curl and the like and sensitive to the tension condition are easy to scratch and damage the fabric, and are inapplicable.
Therefore, when dyeing the above special fabric varieties, dyeing enterprises have to select other types of dyeing machines for dyeing, such as the conventional long-tube overflow jet dyeing machine or gas-liquid dyeing machine, which has a large bath ratio, low efficiency, high energy consumption and high sewage treatment cost. And the gas-liquid dyeing machine has high equipment cost and different styles of processed fabrics. There is therefore a need for an improved and innovative construction of overflow jet dyeing machines to adapt to the specific fabric described above.
The structural shortcoming of the existing tank type overflow jet dyeing machine is as follows:
1. the nozzle system generally has only one set of circular annular flow nozzles with annular gaps. The circular ring-shaped dye liquor fluid is sprayed, after the fabric is guided into the circular circulation nozzle through the cloth lifting wheel, the dye liquor supplied by the main circulating pump is wrapped and driven into a cloth guide pipe by the circular ring-shaped fluid state with larger kinetic energy, and then the fabric is swung into a cloth storage groove by the cloth guide pipe along with the driving of the dye liquor to enter the next circulation, so that the fabric is accelerated by the larger impact force of the circular circulation nozzle fluid, and larger warp tension and weft bending stress exist between the nozzle and the cloth lifting wheel; and secondly, when the annular liquid flow sprayed by the circular nozzle passes through the cloth guide pipe, the flow velocity is reduced, the driving force is reduced, the instantaneous acceleration effect of the fabric is reduced, the actual running speed of the fabric is slow, the fabric speed required by the process is difficult to ensure, during the running process of the fabric, great speed fluctuation and drafting tension fluctuation exist, meanwhile, the driving force for expanding in the weft direction is absent, the weft has great bending stress, the weft of the fabric is difficult to expand, and the final quality effect of the fabric surface is not favorable to ensure.
2. The cloth guide pipe connected to the circular circulation nozzle is also used as a cloth swinging pipe. The cloth guide pipe is structurally connected with a set of link mechanism, takes a circular circulation nozzle point as a center of a circle, takes the length of the cloth guide pipe as a radius, and swings the fabric led into the cloth guide pipe into the cloth storage tank along with dye liquor fluid with corresponding frequency and amplitude to enter next circulation. The fabric is driven by the swing of the cloth guide tube along with the swing motion of the cloth guide tube, the force of the swing motion, namely the swing force, is applied to the fabric by the cloth guide tube, and the longer the cloth guide tube is, the longer the fabric in the cloth guide tube is, the larger the swing force is. The warp tension is further increased by the swinging component force in the warp direction, and the bending and twisting of the weft are further increased by the swinging component force in the weft direction. Therefore, this oscillating movement of the fabric causes several disadvantages:
firstly, this section of fabric between the wobbling origin of fabric for carrying cloth wheel and the nozzle, not only have along warp to the direction motion, still along the torsional motion of swing angle change, further increase the warp of this department of fabric to the torsional force of stretching tension and weft, simultaneously, still produce along carrying the gliding motion of cloth wheel axis direction, increaseed the friction between fabric and the cloth wheel surface of carrying, especially to the frivolous fabric that the atress sensitivity is high, very easily cause the scotch damage.
And secondly, the addition of swinging force on the fabric in the cloth guide pipe increases the warp stretching, the weft is more bent and is more difficult to expand, and the elastic knitted fabric with more sensitive stress, especially the open-width knitted fabric easy to curl, easily generates dyeing defects such as dyeing streaks, dead folds and the like due to the difficult expansion of the weft, and is difficult to ensure the quality requirements such as the final cloth cover gram weight, the shrinkage and the like.
Thirdly, because the cloth of the cloth guide tube is arranged in the cloth groove in a way that a section of circular arc-shaped track is arranged and accumulated, the shape of the cloth groove opening is generally rectangular, and the cloth arranging and falling track is not completely matched with the shape of the cloth groove, the cloth arranging and falling mode of the cloth guide tube is easy to form unstable cloth stacking state after the cloth is arranged in the cloth groove, and phenomena of knotting at the bottom of winding and unsmooth cloth moving caused by cloth turning and disorderly cloth are easy to generate.
