Although there is still a long way to go to fully implement environmental protection sizing in the industry, after more than ten years of appeal and active promotion, people have increased environmental awareness, the introduction of national energy conservation and emission reduction policies, and the ban on imports of PVA-containing slurry cloth in developed regions such as Europe. Due to restrictions, many companies have actively implemented environmental protection sizing.
The practice of pioneering companies shows that implementing environmental protection sizing is not only energy-saving and emission-reducing, but also environmentally friendly. It can also reduce production costs and improve product quality. Their active exploration proves that environmental protection and reducing costs are not two paradoxes.
Environmental protection can survive and develop According to the results of the national pollution source survey, among the 39 industries, the COD of the textile industry accounts for 18.53% of the total national emissions, of which 55% is caused by dyeing and desizing. That is, 1/10 of the national COD emissions are related to weaving sizing. The 1/10 COD emissions are mainly caused by the use of chemical pulps such as PVA used in warp sizing. At present, the country has higher and higher requirements for energy conservation, emission reduction, and environmental protection. In Europe and other developed regions, imports of PVA-containing pulp fabrics have been banned. Environmental issues have affected the survival of enterprises and the sustainable development of the industry.
It is understood that a dyeing factory in Shandong has once exceeded the standard due to desizing waste water, a one-time fine of 6 million yuan by the local government, the product is often affected by PVA slurry and become defective. The fine of 6 million yuan penetred the nerves of the factory's leaders and employees and immediately decided to stop using PVA and use all of the cleaning slurry.
Jiangsu Lianfa textile responsible person said that most companies are still using PVA sizing, but with many countries requesting textiles without PVA, no PVA sizing is a trend. As the company continues to grow and develop, it is necessary to actively explore environmental protection sizing and own its own core technologies in order to further strengthen itself.
In order to enhance the awareness of corporate social responsibility, and make the environmental protection sizing work attract the attention of the whole industry, especially the leaders of operating companies, the China Cotton Textile Industry Association will start the selection of the annual active promoters of environmental protection sizing in the cotton textile enterprises from this year. According to the company's application materials, the expert group scored in accordance with the relevant indicators. After ranking the total score, Xiao Wei, general manager of Jiangsu Yulun Textile Group Jingjiang Yufu Textile Co., Ltd. was named the outstanding promoter of 2011 environmental protection sizing; Luoyang White Horse Wang Hongtao, deputy general manager of Group Co., Ltd., Zhao Zhihua, assistant to general manager of Jiangsu Dasheng Group Co., Ltd., and Wu Qinxia, ​​deputy general manager of Henan Xinye Textile Co., Ltd., were named as the 2011 2011 environmental sizing active promoters.
Xiao Wei said in an interview that the promotion of environmental protection sizing in the industry is not only in line with the current era of energy-saving emission reduction and low-carbon life, but also a good thing for the benefit of future generations. As a corporate manager, in addition to the pursuit of corporate profits To maximize, we must also shoulder more social responsibility for environmental protection.
Economic and Social Benefits Due to the simple calculation of slurry cost, the idea that “without PVA will increase the cost†has become an important factor for some companies to refuse to abandon the use of PVA slurry. However, the practical effect of implementing environmental sizing on many enterprises has strongly refuted this argument.
In recent years, Nanyang Textile Group Co., Ltd. has started to implement energy-saving and environmental-friendly sizing on the conventional cotton poplin series. According to calculations, only one sizing can save the company a cost of 326,460 yuan. Since this series of products uses environmentally friendly slurry that is free from pollution and de-slurry, and the product quality is stable, not only does the printing and dyeing plant reduce the cost of desizing and pollution control, but downstream companies also fully utilize the brand of environmentally friendly fabrics to expand exports and expand. The market has increased the prices of grey cloths, cloths and garments. Due to the successful application of environmentally friendly energy-saving sizing, Nanyang Textile Group's products in this series are in short supply in the market. At present, the output of this series of varieties has accounted for more than 20% of the company's total grey cloth output, and the profit has also been increased by 0.2 yuan/m from the previous year. Calculated at an annual output of 6 million meters, the company can increase profits by 1.2 million yuan for the entire year. Improve the company's product market competitiveness and economic benefits.
Jiangsu Yulun Company began trials of environmental friendly slurries instead of PVA slurries in 2007. By the end of 2009, it basically achieved no PVA sizing, and the overall slurry cost not only did not increase, but also decreased. Xiao Wei said that the key to cost savings lies in the full study of the properties of the slurry, and considering the performance of the sizing equipment and production varieties, including the weaving machines, in a rational and scientific manner. It is not simply used routinely, but rather personalized. The application can save slurry cost under the premise of guaranteeing sizing quality, stabilizing and improving the production efficiency of the loom.
In the process of promoting environmentally friendly sizing, Yulun Company actively explores, first and foremost, an environmentally friendly slurry that is suitable for its own production. At present, there are many types of pastes on the market that can be substituted for PVA, and the performance difference is also large. Through communication and experiment with the slurry manufacturers, one or more environmentally friendly pastes suitable for the production of the company are finally selected. Second, according to the performance of the environmental protection slurry, combined with the production characteristics of the sizing type, a reasonable slurry formulation and sizing process are preferred. Thirdly, we coordinated and cooperated in various aspects such as production management, sizing operation and sizing equipment, focused on production details, and gave full play to the performance advantages of environmental protection slurry. Through all-round cooperation in all aspects, we can not only ensure the stability of production and product quality but also save production costs without using PVA slurry.
In order to improve the quality of the sizing agent, PVA has been verified for many years in the process. It is a good sizing material, which makes it difficult for many companies to abandon it. How to ensure sizing quality without using PVA?
In this regard, Xiao Wei believes that since the 1960s and 70s of last century, the use of PVA slurries has gone through 30 to 40 years. The vast number of cotton textile companies have accumulated extensive experience in the practical application of PVA slurries. The implementation of PVA-free environmental sizing now requires a process of cognition and mastery for the majority of textile companies, not only in the use of technology but also in the ideological concepts.
According to reports, Yulun has encountered many resistances when it started to use environmentally friendly slurries. Many operators do not understand the performance of environmental protection slurries. They do not dare to drive cars when the viscosity of the slurry is slightly lower, and sometimes the technicians assume all the charge. In the case of a yarn quality risk, the car workers did not dare to drive. Xiao Wei believes that this has a considerable relationship with the characteristics of high viscosity stability of PVA pastes that we have mastered over the years. In the sizing process, due to the brittleness of the starch film of the modified starch slurry and low elongation at break, it is easy to produce many problems such as falling pulp and many brittle breakages. Therefore, it is necessary to maintain a high regain of sizing and a slightly higher sizing. The rate, in particular, controls the temperature of the pre-baking drying cylinder and the elongation rate of the sizing wet zone. In the management of sizing production, it requires the sizing workers to accurately grasp the timing of slurry mixing and slurry supply, and to reduce the time required to adjust the slurry length. The problem of degraded slurry quality and instability. Yulon's sizing stoppers, after mastering the requirements for the use of environmentally friendly sizing agents, found that the good shaft rate of the weaving shaft was increased, the sizing yarn was reduced in parallel, and the sizing cloth was not.
The relevant technical staff of Nanyang Textile Group believes that PVA slurry has good sizing performance and has always been the preferred slurry for high-strength and high-density sizing. Everyone needs to be assured, and the quality of sizing usually arises. The first thing that comes to mind is PVA. The dosage is not enough, which has become a habitual mode of thinking for many textile companies, especially sizing operators, grassroots management personnel and technical personnel.
Therefore, if you want to promote energy-saving and environmental-friendly sizing without PVA in your company, you must first change the traditional thinking of these people and let them fully accept the concept and benefits of energy saving and environmental protection sizing. Secondly, after adopting energy-saving and environmentally-friendly pulp, the effect of sizing should reach the requirements of weaving and increase. Systematic research and exploration are needed. Improvements must be made in the process technology, and the operating level of the slasher must be higher. , handle broken head, drop shaft, wear skein, etc. must be fast, accurate and stable. Due to the high sizing requirements for energy-saving and environmental protection slurry, it is necessary to have a high degree of responsibility and discipline from the operator to the manager. A complete set of assessment and inspection mechanisms must be established to ensure the smooth progress of the energy-saving and environmentally friendly sizing process. Try to make the sizing effect the best.
Relevant experts believe that environmental protection sizing not only saves energy and reduces emissions but also protects the environment. It also provides the necessary guarantee conditions for improving the quality of dyeing and finishing processes. People have higher and higher requirements on the quality, color, feel and functionality of fabric products. To achieve these requirements, the quality of the pretreatment of dyeing and finishing is the key link, and the problem of PVA desizing is also highlighted. With PVA sizing the grout is not net due to desizing, there will be differences in the color shade and depth of dyeing, affecting the durability of functional finishing, affecting the finishing effect of no-iron, waterproof, and oil-proof. After the promotion and application of PVA-free sizing technology, MediaTek improved the quality of finished products and the grade of fabrics: The effect of de-sizing the non-PVA sizing fabric is obviously better than that of PVA, and the durability of the functional finishing of the fabric is better. The color of the fabric Brightness and feel have been significantly improved.
In addition, the biochemical dyeing and finishing process can not only effectively reduce the number of processing steps, shorten the processing time, reduce energy consumption and water consumption, but also significantly reduce the processing cost. However, the prerequisite for the application is that it cannot contain PVA. Therefore, PVA-free sizing has become an urgent problem to be solved in order to improve the quality of dyeing and finishing processes and to apply biotechnology.
The practice of pioneering companies shows that implementing environmental protection sizing is not only energy-saving and emission-reducing, but also environmentally friendly. It can also reduce production costs and improve product quality. Their active exploration proves that environmental protection and reducing costs are not two paradoxes.
