How to choose textile auxiliaries? Aug 15 , 2022

In order to adapt to the development of the textile industry, manufacturers invented textile auxiliaries. There are many kinds of textile auxiliaries, each with different functions, such as leveling, color fixing, penetrating, degreasing, moisture absorption and perspiration, softener with good hand feeling, etc. Due to the different functions, you need to pay attention when choosing. The following summarizes the considerations for the selection of textile auxiliaries.

1. Engineers must have basic knowledge of textile auxiliaries

It is the premise of choosing textile auxiliaries. In order to make good use of additives, we must first understand the basic concept, structure, performance and characteristics of additives. If any abnormal situation is found, it can be analyzed and dealt with in time. Subjective analysis should be avoided and the application of textile auxiliaries ignored. In an experienced business, supervisors or workers use some additives and techniques based on their own experience and reject others. This is due to a lack of knowledge and technology that prevents them from distinguishing between good and bad additives and using new ones. In addition to improving the quality of talents, it is also very important for enterprises to pay more attention to the application of textile auxiliaries. Therefore, when a factory uses a new auxiliary, the supplier must inform the structural class of the auxiliary. For example, regarding the kind of softener, amino silicone oil softener, hydrophilic silicone oil softener, fatty amide softener, imidazoline or fatty acid paraffin softener. Only then can we get it right and avoid mistakes.

2. Pay attention to the effect of textile auxiliaries and avoid numerical traps

There are many brands of textile auxiliaries on the market, and the effects of textile auxiliaries are also different. However, most manufacturers regard the actual content of additives as the standard for the effectiveness of additives, ignoring the impact of the product on the fabric itself, resulting in production losses. We should choose textile auxiliaries that have a basic understanding of the product.

3. Test the acid and alkali resistance of textile auxiliaries

In this way, it is easy to judge whether the textile auxiliaries can meet the needs of the process. The acid and alkali resistance of additives varies greatly. Anionic surfactants are generally resistant to alkalis but not acids. Phosphate esters have the best alkali resistance, while carboxylic acids have the worst acid resistance. Cationic surfactants are generally acid and alkali resistant. Nonionic surfactants are resistant to weak bases and weak acids, but not solid acids and strong bases.
