Textile dyeing and finishing system

Supporting industry intelligent development

The printing and dyeing industry, as an important part of the textile industry, involves many disciplines such as physics, chemistry and biology. It is a technology intensive and high-tech industry. It is also an important technical support for industries such as high value added clothing, home textiles and high-tech textiles. It is also an important part of textile color, pattern, functionality, and the inherent quality of textiles. Therefore, it has the characteristics of high creativity, high market control and high added value.

When asked how many achievements have been made in the intelligent system of textile dyeing and finishing for so many years in Changzhou, Gu Ren told reporters that the results can be summed up in six aspects: the realization of on-line detection of key technological parameters, the realization of automation of single station, intelligent control, production process, digital network information management and control system, logistics automation, intelligence, information technology, energy information management and control system, and environmental intelligent information management and control system.

The new era of textile finishing and weft opening has been opened.

Won the "textile light" 2017 China Textile Industry Federation science and technology award first prize of the Hawk Vision photo intelligent image finishing weft knitting machine, identified by the China Textile Industry Federation experts identified as the leading international level.

The Hawk vision intelligent image finishing and weft knitting machine has the world leading technology to solve the floral deformation, weft and weft bending, and the world's leading full scan full weft and weft filling technology, which opens the new era of textile finishing and weft finishing.

According to Gu Ren, "this product has realized the automatic detection and pattern shaping of jacquard, yarn dyed, printed, lace, embroidery and so on, and has improved the weft accuracy, expanded the adaptability of varieties, and solved the problem of weft filling, tangle, sanding, light weight, heavy weight, chiffon and other textiles.

Before printing, the printing inspection equipment should match with the standard when testing, and it is necessary to manually compile the standard for the equipment.

Now, the Hawk vision intelligent image finishing and weft knitting machine can automatically judge, learn, discover the rules in the image, and find out the difference between the object and the standard according to the standard.

The whole weft finishing equipment has such a deep learning function, which reduces the demand for labor and improves the accuracy further.

Gu Ren also said that the Hawk Vision Vision intelligent image finishing and weft knitting machine is the "Hawke Wei" brand, relying on its strong European technological background and the great technological R & D strength of Hong Kong, and has pioneered the leading international "full scan full weft and finish weft technology". The full width scanning is more than 8000 monitoring points, so that the floral deformation, skew and weft bending problems of textiles that can not be corrected and identified by photoelectric finishing can be completely solved.

It uses new technology to solve the problem of textile flower deformation and the problem that the photoelectric weft straightening machine can not be corrected.

It can be used for printing cloth, dyed fabric, jacquard cloth and other textiles. The raw materials are heavy cloth, twill, wool cloth, knitted fabric and denim.

It is suitable for digital printing and sizing process, heat pfer printing process and so on. It has fundamentally improved the quality of textile finishing.

It solved the industry problem of on-line monitoring system.

As we all know, knitted fabric is easy to be stretched and narrowed due to its own weaving and material. During the processing and finishing process, the density of the knitted fabric must be automatically controlled in order to ensure the stability and quality of the knitted fabric.

Gu Ren told reporters that the shape control machine adopts the intelligent image technology to monitor the weft density of the fabric on the side of the shaping process. When the weft density condition of the fabric can not reach the set value, the weft density is adjusted to the desired state in real time through the super feed adjustment system, so as to ensure that the weft density is uniform, the quality of the knitted fabric per unit area is achieved, the success rate is increased, and the high quality textiles are guaranteed.

It is understood that the printing process of rotary screen printing machine often appears random blocking and running flowers, resulting in mass defects.

The online detection system of rotary screen printing machine created by Changzhou R & D has perfectly solved the industry problem.

The product realizes automatic detection and alarm for blocking in printing process, greatly reduces the skill requirements and labor intensity of the operator, and improves the finished product rate, which is an essential product of medium and high grade printed fabrics.

The online inspection system of rotary screen printing machine was included in the eleventh batch of China in October, 2017 in October.

Directory of advanced technologies for energy conservation and emission reduction.

In the process of knitted printing, due to the reasons of printing net head or dyestuff and net head contamination, white spots (lack of printing) and color spots (stains) often occur on cloth.

As the printing machine can not be shut down frequently, some defects will occur periodically in the same place once they occur, resulting in continuous waste.

Compared with some random black dots and ink spots, the continuous waste in printing process will have a greater impact on the quality of the entire batch of cloth.

Gu Ren said that the online detection system of knitted printing and clogging was installed on the printing machine to monitor the 100% quality of cloth. When the defects were found, it could be timely alerting to remind workers to adjust the printing machine so as to improve the quality of products.

The system uses machine vision and image processing technology to realize automatic detection and alarm of blocking in printing process, and real-time and continuous detection of printing quality. The whole process is continuous real-time detection and less manual intervention.

It can greatly reduce the skill requirements and labor intensity of the operator, and improve the finished product rate, which is an essential product of medium and high grade knitted printed fabrics.

Improve product quality and success rate.

It is understood that the cylinder is added auxiliaries.

After that, whether the pH value of the dye in the cylinder meets the requirements, and the acidity and alkalinity increase gradually with the increase of temperature in dyeing process, which can easily lead to poor dyeing or hair color. At the same time, it will also affect the dye adsorption and fixation effect of the fabric.

Therefore, the pH value should be controlled within a reasonable range.

How to test the pH value of cylinder dyeing environment still has two difficult problems: how to improve reliability and accuracy.

According to Gu Ren, the characteristics and advantages of the on-line measurement and control system for the cylinder pH value include the realization of on-line detection and control of the PH value of the cylinder dyeing environment, so that the pH value environment condition can be monitored in time. The system can perform fault diagnosis and prompt functions, achieve the purpose of fault tolerance testing, realize the pformation of PH value from the operator experience to the automatic detection and control of the system, and the manager can understand the current pH value of the cylinder dyeing environment in real time, and improve the product quality and the success rate.

Changzhou Hongda has developed a steam efficient utilization technology, which has been selected in the national development and Reform Commission's national key energy saving and low carbon technology promotion directory, and opened a new era of baking tank drain intelligence.

Gu Ren told reporters, "to increase the efficiency of the dryer, the water from the steam should be removed. Otherwise, the oven temperature will not rise if the steam is in the oven.

How did the water become sparse? In the past, it was through mechanical means that the dredging method was good or not! Good! Because it has been used for more than 100 years.

However, there are some shortcomings in this equipment. It does not know the situation of water and steam inside it, and can not automatically distinguish it.

Now we have made an automatic drainage system to accurately control the internal water.

At the same time, it can automatically distinguish whether the siphon in the trap is broken or not.

The HD-GX intelligent electric drainage system developed by Changzhou Hongda independently operates without manual operation. It has precise automatic drainage and no air lock. The system has intelligent self draining and intelligent self checking function. The system has the function of manual opening and closing control valve, convenient for maintenance and testing, intelligent calculation of valve opening time, automatic control of valve opening and closing, and intelligent fault judgement function and abnormal automatic alarm function of the system, and steam usage is more than 15% energy saving.
