Description

 The invention relates to the textile industry, namely to the technique of finishing production, and can be used for processing textile materials in the processes of desizing, preparation for dyeing fabrics, bleaching, as well as coloring of textile materials based on natural, synthetic fibers and mixtures thereof.

A known line for bleaching fabrics opposite LOR-140, which is designed for decoction and bleaching of cotton fabrics, as well as fabrics from a mixture of cotton and chemical fibers. The line contains a refueling device installed during the fabric processing cycle, three impregnation baths for impregnating the fabric with a technological cooking composition, a steaming chamber, six washing baths, three impregnating baths for impregnating with a bleaching technological solution, a steaming chamber, six washing baths, a tumble dryer and a selective device [1, p.501]
LOB-140 and LOB-180 decoction and bleaching lines are also known, designed for decoction, bleaching and dyeing of cotton and cotton-laced fabrics. The lines contain a filling device, an impregnating machine for impregnation with an alkaline solution, a steaming chamber, four washing baths for washing from alkali, an impregnating bath for impregnating fabrics with sulfuric acid, two washing baths, an impregnating machine for impregnating with an alkaline peroxide solution, a steaming machine, three washing baths , spin, installation for correcting warps of a duck, a drying drum and a selective device [1, p.531]
The disadvantages of these lines for the preparation of fabrics are large overall dimensions, large metal consumption and the inability to use them for dyeing fabrics.

 Known line dyeing and drying type LKS-140, designed for dyeing cotton and blended fabrics with sulfur, vat active dyes [1, p. 65] containing a filling device for impregnation with a dyeing solution, a steamer for fixing the dye, washing baths, a tumble dryer and a sample device.

 The disadvantages of this line are also large overall dimensions and metal consumption and the inability to carry out other finishing processes, such as whitening.

The well-known line LKK-180 for continuous dyeing with cubosols according to the nitrite method of fabrics made from cellulose fibers (cotton, viscose). The line contains a filling device, devices for impregnating fabric with a dyeing solution, an acid solution, eight washing machines, a device for correcting skew of a duck, a grinding device, a drying drum machine and a selective device [2]
This line has a number of drawbacks that significantly limit the possibilities of its use, namely the impossibility of using the line for other processes of finishing production except for dyeing, the maintenance of its operation with toxic emissions of nitrogen oxides in the working area, low reliability due to corrosion of acid-impregnating baths and large overall dimensions and metal consumption.

 The technical result of the invention is the expansion of technological capabilities of equipment, namely the creation of a universal line for processing textile materials, on which it would be possible to carry out both preparation processes (desizing, preparation for dyeing fabrics, bleaching), and the processes of coloring of textile materials based on natural, synthetic fibers and mixtures thereof.

 This is achieved by the fact that in the line for processing textile materials containing a filling device, devices for impregnating the material with a technological solution, washing, correcting warps of the weft, drying, and also a selective device, after the device for impregnating a technological solution along the movement of the processed material, at least at least one device for ultraviolet processing of the material.

 The line can have one or more UV processing devices, which can be installed either after one or after each, if there are several, pluses, or one after another.

 As the technological devices listed above, any appropriate commercially available equipment can be used. For example, as a filling device, a rolling peripheral machine and other devices for impregnating the material with a technological solution can be used as two-shaft, three-shaft pluses, impregnation baths, pluses with an engraved shaft or an aerosol solution installation and others; washing devices for washing baths, roller or tower, and others; devices for correcting warp of a duck; installation of a correction for warping of a duck and others; drying devices, a tumble dryer, an air-roller dryer, a tenter dryer and others; selective devices rolling peripheral machine and others.

 Compared with the well-known line of cubic soiling, the proposed line allows you to significantly expand the technological capabilities of the equipment: firstly, the line allows you to carry out the processes of tissue preparation (desizing, capillarity, bleaching), and dyeing fabrics, i.e. the line is universal in its technological purpose, and secondly, in dyeing, the range of processed fabrics is significantly expanded. If the known line allows you to dye only cotton fabrics, then on the proposed line you can also dye fabrics made of protein fibers (silk, wool), fabrics made from a mixture of natural and synthetic fibers (cotton, flax, viscose lavsan, containing wool with lavsan, natural silk with viscose other).

 The expansion of technological capabilities of the equipment is also ensured by obtaining fundamentally new coloristic effects of dyeing. This means one-sided dyeing of the material when the front side of the fabric is painted, but the wrong side is not. At the same time, at least two-fold dye savings are achieved, which is an additional advantage. Two-sided dyeing can also be carried out when both sides of the material are painted in different colors. In addition, it seems possible to obtain coloristic effects on fabrics that mimic photo printing.

 Thus, the new coloristic effects of dyeing can improve the consumer quality of finished textile materials.

 Another advantage is that the dimensions and metal consumption of the equipment are significantly reduced, its efficiency is increased by eliminating two impregnating acid baths from the composition of the line and reducing the number of washing machines when dyeing technology is implemented on it. Taking into account the fact that acid baths are made of expensive and scarce metal-titanium, equipment is cheaper. In addition, the reliability of the equipment increases, since corrosion of the impregnation baths with sulfuric acid is excluded.

 At the same time, environmental friendliness is significantly improved during the operation of the equipment, since the release of toxic nitrogen oxides into the working zone is excluded and sulfuric acid is absent in the wastewater.

 The proposed device can also be used to implement other photochemical technological processes based on the use of ultraviolet processing of textile materials.

 Thus, the invention allows to achieve the proposed technical result, i.e. expand the technological capabilities of the dyeing equipment both by providing the preparation and coloring of textile materials from natural, synthetic fibers and their mixtures, and by achieving new coloristic effects in dyeing.

 The drawing shows a line for processing textile materials.

 The line contains a filling device 1, a device 2 for impregnating the material, a device 3 for ultraviolet processing of the material, a device 4 for squeezing the material, a device 5 for washing, a device 6 for correcting warps of the weft, a device 7 for drying the material, a selective device 8.

 The line works as follows.

 Textile material using a filling device 1 is sent to an impregnating device 2 for applying technological solution to the fabric. The impregnated fabric enters the device 3 for ultraviolet treatment, in which, depending on the used technological solution, the material acquires either capillarity, or whiteness, or color, or another property. Moreover, in dyeing, using various impregnation devices, as well as changing the wiring of the material and using various devices for ultraviolet processing, it is possible to carry out ordinary smooth dyeing, as well as single-sided dyeing, polychromatic dyeing, as well as dyeing that mimics the effect of photo printing. So, for example, using the usual two-shaft plusing as an impregnating device and changing the wiring of the fabric in the device for ultraviolet treatment, you can get the usual smooth dyeing or one-sided and two-sided. Using the installation for aerosol application of the dyeing solution, it is possible to obtain patterned and polychromatic dyeing of the fabric, and using the UV installation for photo printing, colorize fabrics with the effect of photo printing.

 The fabric treated with ultraviolet radiation is washed in the washing device 5, and then the weft is corrected in the device 6, after which it is dried in the device 7 and selected by the device 8.
