Description

Technical Field

[0001] The invention relates to the technical field of textile printing and dyeing, and in particular to a yarn waterless printing and dyeing production process and a production line. Background Art

[0002] There are three conventional yarn dyeing (also known as yarn printing and dyeing) methods: ① Hank dyeing - the loose hank is immersed in a special dyeing vat, which is a very costly dyeing method; ② Cheese dyeing - the yarn dyed by cheese is wound on a perforated cheese, and then many cheeses are loaded into the dyeing vat, and the dyeing liquid circulates, and the fluffy effect and softness are not as good as hank dyeing; ③ Warp beam dyeing - a large-scale package dyeing, before shuttle manufacturing, the warp beam (warping) must be made first, and the yarn of the entire warp beam is dyed, such as the combined sizing dyeing machine and the warp beam yarn bundle dyeing. Because it is a warp beam, it is mostly suitable for shuttle dyeing.

[0003] However, the conventional yarn dyeing method has a complicated process, uses a lot of fuel and water, and usually requires high temperature, which leads to serious environmental pollution. In recent years, a new dyeing technology called waterless yarn dyeing (also known as waterless yarn printing and dyeing) has been born. It usually achieves dyeing by directly soaking and penetrating the waterless dyeing solution (dye) into the yarn; in addition, the stable and large-scale application of supercritical CO2 waterless printing and dyeing technology has been achieved.

[0004] However, the existing waterless yarn dyeing technology still has many problems as a whole:

[0005] 1. This method of directly soaking and penetrating the yarn with anhydrous dyeing solution (dye) still has a relatively complicated process flow, and the waste and consumption of dyes are relatively large, the equipment is bulky, and most importantly, it is not suitable for dyeing small-scale personalized colored yarns (this type of yarn is usually dyed into many colors in small batches according to market demand);

[0006] 2. Supercritical CO2 waterless printing and dyeing technology requires large and expensive dyeing equipment, which is not suitable for dyeing small-scale personalized colored yarns;

[0007] That is, there is a lack of dyeing equipment / production line suitable for small-scale personalized colored yarns, and thus it is impossible to achieve a production process with a simple process flow, low equipment investment, and good dyeing effect; specifically, in the process of yarn dyeing production by the waterless yarn dyeing production line, a conveying device is usually required for conveying work, but the yarn is prone to carry a large amount of fluffy debris that is difficult to remove, and the traditional yarn conveying device cannot remove the fluffy debris. At the same time, the traditional yarn conveying device cannot adjust the tension of the conveyed yarn, so that the yarn will be damaged by tension during the conveying process;

[0008] When the yarn waterless dyeing production line is used for yarn dyeing production, the dye will leak out when the existing yarn waterless dyeing dyer is in use, affecting the working environment of the production workshop and causing the production workshop to be polluted. In addition, the existing yarn waterless dyeing dyer cannot recycle the dye when it is in operation, resulting in waste of the leaked dye and increasing the production cost.

[0009] When the yarn waterless dyeing production line is used for yarn dyeing production, the dye is not firm after the yarn is dyed and is easy to fade, so it is necessary to use a steam fixing device for color fixing treatment. However, during the use of the existing steam fixing device, the steam leakage and discharge are easy to affect the staff, and the discharged steam also causes waste, which is inconvenient to use;

[0010] In the process of yarn dyeing production, multiple yarns are transported to the "yarn cleaning device" after being dyed. The yarn surface is cleaned during the forward conveying process to remove excess dyes and other impurities on the surface. The cleaning effect needs to be ensured. Therefore, yarn cleaning is an indispensable process in yarn production; such as China Invention Patent Publication No. CN 217678089 A yarn cleaning device of U comprises a device shell, the device shell is provided with a water tank, a water inlet pipe of a water pump is arranged on the right side of the water tank, the water pump is installed on the top right side of the device shell, the input end of the water pump is connected with the water inlet pipe, and the output end is connected with the water outlet pipe, a plurality of nozzles are evenly installed on the water outlet pipe, the nozzles are supported by nozzle brackets, the nozzle brackets are installed between the inner wall of the tank body of the water tank, an upper hub and a lower hub are rotatably installed below the nozzle bracket, and a filter is installed below the upper hub and the lower hub; the device uses the nozzle to rinse and clean the yarn, but due to the fixed rinsing direction of its structure, the side of the yarn away from the nozzle cannot be directly rinsed clean, thereby forming a rinsing dead angle, which leads to a decrease in the yarn cleaning efficiency of the device.

[0011] Based on the above situation, the present invention proposes a yarn waterless printing and dyeing production process and production line, which can effectively solve the above problems. Summary of the invention

[0095] 6) Each cleaned yarn is dried separately, and finally taken up by a take-up device to obtain waterless dyed yarn.

[0096] The yarn waterless printing and dyeing production process of the invention adopts a self-designed yarn waterless printing and dyeing production line to perform yarn waterless dyeing, which is very suitable for dyeing needs of small-scale personalized colored yarns, has a simple process flow, small equipment investment, and good dyeing effect.

[0097] In practical applications, the traction rollers of the present invention can be provided in a required number as required to provide traction power or auxiliary traction power, and can be driven by a driving mechanism commonly used in the art. In addition, a required number of driven traction rollers can be provided as required to guide / support yarn delivery.

[0098] In practical applications, in step 1), the number of the bobbins is at least 1, preferably greater than 3; the number of yarns pulled in the corresponding subsequent steps is at least 1, preferably greater than 3.

[0099] In practical applications, in step 1), the number of the bobbins is greater than 3; and the number of yarns pulled in the corresponding subsequent steps is greater than 3.

[0100] In practical applications, the dyes used in the dyeing device are selected according to the type of yarn that needs to be dyed.

[0101] Preferably, in step 3), the dye used in the dyeing device is an anhydrous dye.

[0102] refer to Figure 1-22As shown, in some embodiments, the yarn waterless printing and dyeing production line includes a pay-off device, a feed-in device, a waterless dyeing device, a steam color fixing device and a cleaning device arranged in sequence in the yarn direction; a traction roller is arranged between the pay-off device, the feed-in device, the waterless dyeing device, the steam color fixing device and the cleaning device;

[0103] The pay-off device, the feeding device, the waterless dyeing device, the steam fixing device and the cleaning device can all allow multiple yarns to pass independently;

[0104] The waterless dyeing device comprises a fixing frame and a plurality of different dyeing devices independently fixed on the fixing frame.

[0105] refer to Figure 2-5 As shown, the line feeding device described in the present invention includes a bottom plate, and four fixing holes are opened on the top of the bottom plate, which will be more convenient to operate when installing and fixing the bottom plate. Two brackets are fixed on the top of the bottom plate, and the first line roller is rotatably connected between the inner walls on both sides of the bracket through bearings, and the side walls of the bracket are rotatably connected with a rotating shaft through bearings. Transmission wheels are fixed on the surfaces of the two rotating shafts, and the two transmission wheels are connected by belt transmission, so that the two rotating shafts can be driven to rotate at the same time under the action of a motor, so as to save production costs. Gears are fixed on the surfaces of the rotating shafts, and two L-shaped plates are slidably connected to the inner wall of one side of the bracket. Teeth matching the gears are equidistantly fixed on the L-shaped plates, and the teeth are respectively meshed with corresponding gears. A cleaning plate is fixed on one side wall of the L-shaped plate, and a cleaning cloth is fixed on the cleaning plate. Two supporting plates are fixed on the top of the bottom plate, and two second line rollers are rotatably connected between the inner walls on both sides of the two support plates through bearings. A cross plate is fixed between the two supporting plates, and two cylinders are fixed on the top of the cross plate. The tops of the two cylinders A U-shaped plate is fixed at the outlet end, and the inner walls on both sides of the U-shaped plate are rotatably connected to the third line roller through bearings. During the use of this device, after the device is installed in a suitable position, one end of multiple yarns can be wound around the first line roller, the second line roller and the third line roller respectively, and then the yarn can be dragged by the traction mechanism body [such as the traction roller] on the equipment. When the yarn is moving, the motor can be started to drive the rotating shaft to rotate. With the cooperation of the gears and teeth, the two L-shaped plates can be driven to move in the opposite direction at the same time when the rotating shaft rotates. When the L-shaped plate moves, it will drive the two cleaning plates to approach each other. At this time, the cleaning cloths on the two cleaning plates will fit with the surface of the yarn, so that when the yarn is transported and moved, the plush debris adhered to its surface can be removed.
