1. Emphasizing Solid Content and Neglecting Physical and Chemical Analysis

Expert advice: Many additives users attach great importance to solid content and use the combination of content and 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, and solid content is only one indicator. After conducting a comprehensive physical and chemical analysis, a large sample trial will be conducted, and the solid content will only be determined after preliminary determination, as the basis for checking the quality of the auxiliary batch.

2. Emphasizing Unit Price and Neglecting Comprehensive Cost

Expert advice: Due to the fierce competition, under the huge cost pressure, many printing and dyeing plants attach great importance to the unit price of auxiliaries, but the unit production cost is very general, not to mention the comprehensive Unit cost of dosage, efficiency, rework, repair, etc. At present, the competition for additives is also fierce, and under the pressure of raw material costs, it is difficult to achieve high-quality and low prices. Compare the price with the same quality and quantity, or compare the quality with the Unit cost; Combined with actual energy consumption, production efficiency, and stability of process quality, calculate the unit comprehensive cost; More importantly, the actual Unit cost should be checked and calculated on a monthly basis to prevent the seemingly low calculation cost and high actual cost.

3. Emphasizing speed and convenience, neglecting long-term stability

Expert advice: Textile printing and dyeing factories require zero inventory and fast delivery of additives, which may seem very scientific, but in reality, they are too strict; Due to the unique strengths of each additive manufacturer, and the difficulty for most additive manufacturers to approach textile printing and dyeing factories, coupled with the timeliness of additive production, it is necessary and reasonable for printing and dyeing factories to prepare a week's inventory usage. For a week, transportation across the country will not be a problem, and printing and dyeing factories will also choose more excellent and stable additives.

4. Emphasizing the role of a master while neglecting objective comparison

Expert advice: This is very prominent in some experienced enterprises, where the supervisor (or master) of the enterprise will use some additives and processes according to their own experience habits and refuse other products; This is not only driven by some interests, but also by limitations in one's own knowledge and technology, making it difficult to distinguish the advantages and disadvantages of additives and not daring to use new ones. This is most prominent in low-end bleaching and dyeing, washing and dyeing, denim and other industries, which is easy to lead to long-term problems such as environmental non-compliance, large batch difference, unstable quality, high actual costs, and difficulties in new product development.
