content: With the intensification of market competition, many textile printing and dyeing enterprises have become increasingly strict and attach importance to the selection of printing and dyeing auxiliaries. Recently, the requirements for eco-friendly environmental protection of textiles have become more stringent at home and abroad, leading to environmental protection and economic problems in the selection of printing and dyeing auxiliaries. Through years of contact with various textile printing and dyeing companies, we have some understanding and understanding of this issue. We will communicate with you here to discuss the environmental protection and economy of printing and dyeing additives. First, the principle of auxiliary selection 1.1 Environmental protection This must be considered first and must be met at present; in the international environment, non-environmental additives will be rejected. In addition to the raw materials, the auxiliaries also have to test and certify the finished products. Intertek has done a good job in this regard. Intertek is not limited to testing, but also provides relevant certification and procurement guidelines to facilitate the choice of textile printing and dyeing companies. 1.2 Applicability This is the intrinsic property of the auxiliaries and the basic requirement; the printing and dyeing auxiliaries give the auxiliary effect of the whole process of textile processing, so that the processing can be carried out smoothly, efficiently and stably. This is the key to the choice of additives, the additives used must meet the processing and quality requirements of the process. 1.3 stability The stability of the quality of the auxiliary products is directly related to the processing quality and processing efficiency of the textiles; the additives with poor stability will seriously affect the quality of the process, causing rework and repair, and directly affecting the cost and delivery time. 1.4 Economics At present, the market is fiercely competitive, and the price of the product becomes more sensitive. Under the premise of satisfying the quality requirements and being stable and reliable, it is wise to use low-cost additives. 1.5 technical support Printing and dyeing companies are increasingly dependent on technical services and support. Strong and effective technical support is an increasingly important competitive tool for auxiliaries. The above is the principle of selecting additives, and it is also the basis for scientific selection of additives for printing and dyeing enterprises. If the printing and dyeing enterprises truly do this, it will be conducive to the sustained and healthy development of their own enterprises, and will also have the effect of the survival of the fittest in the auxiliary industry, which is very beneficial to the sound development of the entire textile printing and dyeing industry. However, at present, the actual situation is that many printing and dyeing enterprises have not made scientific selection of auxiliaries, which has produced many unqualified auxiliaries, and has also affected many printing and dyeing enterprises with poor processing quality, unstable production and low corporate profits. Second, the misunderstanding of the selection of printing and dyeing auxiliaries In the long-term contact and communication with textile printing and dyeing enterprises, we found that many enterprises have many misunderstandings on the selection of additives, mainly in the following four aspects. 2.1 Pay attention to solid content. Ignoring physical and chemical analysis Many auxiliaries users attach great importance to solid content and combine the content with the unit price as the basis for selection. In fact, it is very unwise to do so. Physical and chemical analysis is the basis for checking the quality of additives. Solid content is only one of the indicators. The correct approach should be: after conducting a comprehensive physical and chemical analysis, and then conducting a large sample trial, the initial determination of the solid content is determined as a basis for checking the quality of the batch of the additive. 2.2 Pay attention to unit price and ignore comprehensive cost Due to the fierce competition, under the huge cost pressure, many printing and dyeing factories attach great importance to the unit price of additives, but the unit production cost is very general, but it does not consider the comprehensive unit cost of dosage, efficiency, rework and repair. At present, the competition of additives is also very fierce. Under the pressure of raw material costs, high quality and low price have been difficult to achieve. The correct way is: compare the quality with the same amount, or the unit cost; compare the actual energy consumption, production efficiency, process quality stability, etc., calculate the unit's comprehensive cost; To prevent the seemingly low cost of calculation and the high actual cost. 2.3 Emphasis on speed and convenience. Neglect long-term stability The textile printing and dyeing factory requires zero inventory and fast delivery, which seems to be very scientific. In fact, it is too harsh. Because each additive manufacturer has its own strong products, most of the additives manufacturers are difficult to get close to the textile printing and dyeing factory. Coupled with the timeliness of the production of additives, it is necessary and reasonable for the printing and dyeing factory to prepare the inventory for one week. In a week, shipping around the country is not a problem, and the printing and dyeing factory will choose more excellent and stable additives. 2.4 Pay attention to the role of the master, ignore the objective comparison This is very prominent in some experience-oriented companies. The supervisors (or masters) of the company will use some auxiliaries and processes according to their own experience and reject other products. In addition to being profit-driven, it is more The limitations of their own knowledge and technical insufficiency cannot distinguish the advantages and disadvantages of additives and the dare to use new additives. This is the most prominent in the low-end bleaching, dyeing, denim and other industries, which is likely to cause long-term problems such as environmental protection, non-compliance, large batch errors, unstable quality, high actual cost, and difficulties in developing new products. In addition to the above common problems, there are many other issues. So, how to fundamentally solve and avoid these problems, so that the selection of additives is scientific and effective? Our suggestion is: choose excellent qualified additives manufacturers. Only by selecting excellent qualified additive manufacturers can these problems be fundamentally solved. Third, the significance of choosing excellent qualified suppliers The significance of choosing a good qualified supplier is: · Safe and reliable indicators; · Stable and excellent quality; ·Real cost-effective; · Comprehensive and timely technical support; · Timely cooperation in product development and innovation. Excellent suppliers of qualified additives are not judged by the size of the company, but by the following aspects: (1) Whether it is professional, the time and technology of production; whether there is a production license; (2) Whether to regulate production, whether to strictly control the products according to the ISO9001 standard; (3) How to ensure the eco-friendly nature of the product, whether there is an environmental protection test report and corresponding certificate; (4) Whether there are strong products recognized by the market, and whether there is stable product quality; (5) Whether to comply with commercial regulations and whether to conduct business activities mainly through illegal marketing means; (6) Whether there is product innovation capability, whether there is timely and effective technical support. All of the above are very commendable, so that excellent suppliers of qualified additives have been or are being produced and will be highly regarded by the industry. Fourth, the outlook As the market matures, printing and dyeing auxiliaries are also maturing, and the high-quality additives from various manufacturers are gradually recognized by the industry. We are delighted to see that more and more printing and dyeing companies are beginning to choose the qualified suppliers, and more and more auxiliaries are on the basis of qualifications. Let us select the auxiliaries of excellent qualified suppliers in the whole industry, so that our entire process will be environmentally friendly, reliable, stable and economical, and our textiles will be in an invincible position in international competition. The above are some of our views and experiences on the selection of additives. Many shortcomings are welcome. We welcome everyone to exchange and discuss. We also welcome the criticism.
