Environmental Protection and Economic Selection of Auxiliaries for Printing and Dyein
With the intensification of market competition, many textile printing and dyeing enterprises pay more and more attention to the selection of printing and dyeing auxiliaries. Recently, the environmental protection requirements of textiles at home and abroad have become more and more stringent, which leads to the environmental protection and economic problems in the selection of printing and dyeing auxiliaries. Through many years of contacts with various textile printing and dyeing enterprises, we have some understanding and experience on this issue. We will exchange with you here and discuss the environmental protection and economy of the selection of printing and dyeing auxiliaries.
I. Principles for the Selection of Auxiliaries
1.1 environmental protection
This is the first consideration and must be satisfied at present; in the international environment, non-environmental additives will be rejected. In addition to checking the raw materials, the auxiliary manufacturers also need to test and certify the products. Intertek has made a good exploration in this respect. Intertek is not limited to testing, but also gives relevant certification and procurement guidelines, which facilitates the selection of textile printing and dyeing enterprises.
1.2 applicability
This is the inherent property and basic requirement of auxiliaries. Printing and dyeing auxiliaries endow textile processing with assistant role in the whole process, so that processing can proceed smoothly, efficiently and steadily. This is the key to the selection of additives. The additives used must meet the requirements of processing technology and quality.
1.3 stability
The stability of the quality of auxiliaries is directly related to the processing quality and efficiency of textiles. The poor stability of auxiliaries will seriously affect the process quality, cause rework and repair, and directly affect the cost and delivery time.
1.4 economy
At present, the market competition is fierce, and the price of products becomes more sensitive. On the premise of meeting the quality requirements and being stable and reliable, it is wise to choose low-cost additives.
1.5 technical support
Printing and dyeing enterprises are increasingly dependent on technical services and support. Powerful and effective technical support is an increasingly important competitive tool for assistant manufacturers.
Above is the principle of selecting auxiliaries, which is also the basis for printing and dyeing enterprises to select auxiliaries scientifically. If the printing and dyeing enterprises really do this, it will be conducive to the sustained and healthy development of their own enterprises, and will also have the effect of eliminating the fittest in the auxiliary industry, which is very beneficial to the healthy development of the textile printing and dyeing industry.
However, at present, the actual situation is that many printing and dyeing enterprises have not done a scientific selection of auxiliaries, resulting in a lot of unqualified auxiliaries companies, but also affected many printing and dyeing enterprises poor processing quality, unstable production, low enterprise efficiency.
2. Misunderstandings in the Selection of Auxiliaries for Printing and Dyeing
In the long-term contacts and exchanges with textile printing and dyeing enterprises, we find that there are many misunderstandings in the selection of auxiliaries in most enterprises, mainly in the following four aspects.
2.1 Pay attention to solid content. Ignore physicochemical analysis
Many additives users attach great importance to solid content and take the combination of content and unit price as the basis of choice. 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 method should be: after a comprehensive physical and chemical analysis, a large sample trial will be conducted, and the solid content will be determined after preliminary determination as the basis for checking the batch quality of the additive.
2.2 Pay attention to unit price and ignore comprehensive cost
Because of the fierce competition, under the enormous cost pressure, many printing and dyeing factories attach great importance to the unit price of auxiliaries, but the unit production cost is very general, not to mention the consumption, efficiency, rework, repairs and other comprehensive unit costs. At present, the competition of auxiliaries is also fierce. Under the pressure of raw material cost, it is difficult to achieve high quality and low price.
The correct way is to compare the price with the same amount or the quality with the same unit cost; to calculate the unit comprehensive cost by combining the actual energy consumption, production efficiency and process quality stability; and to check the actual unit cost monthly, so as to prevent the low cost that seems to be calculated and the high actual cost.
2.3 Pay attention to speed and convenience. Neglect long-term stability
Textile printing and dyeing factories require zero inventory and fast delivery of auxiliaries, which seems very scientific, but in fact is too harsh. Because each auxiliaries manufacturer has its own strong products, and most auxiliaries manufacturer is difficult to get close to textile printing and dyeing factories, plus the timeliness of auxiliaries production, it is necessary for printing and dyeing factories to prepare a week's stock consumption. It is reasonable and scientific. For a week, transportation throughout the country is not a problem, printing and dyeing factories will choose more excellent and stable additives.
2.4 Pay attention to the role of teachers and ignore objective comparison
This is very prominent in some experience-based enterprises, where managers (or teachers) will use some additives and processes according to their own experience and habits and refuse other products; in addition to being driven partly by interests, this is more limited by their own lack of knowledge and technology, unable to distinguish the advantages and disadvantages of additives and dare not make them. Use new auxiliaries. This is most prominent in low-end bleaching, washing and dyeing, jeans and other industries, which can easily lead to environmental problems such as substandard, poor batches, unstable quality, high actual costs, difficulties in developing new products and so on.
In addition to the above common problems, there are many other problems. So, how to solve and avoid these problems fundamentally and make the selection of additives scientific and effective? Our suggestion is to select excellent qualified additives manufacturers. Only by choosing excellent and qualified manufacturers of additives can these problems be fundamentally solved.
