Physical and chemical indicators of thread adhesives
Thread adhesives are the most basic components of the fabric manufacturing industry, playing a crucial role in the production process, so physical and chemical testing is an essential part of measuring the performance of thread adhesives. The performance of the adhesive before and after use can be accurately evaluated by testing its physical and chemical properties.
The physical properties of thread adhesives are such as gloss, color, hardness, flexibility, oil absorption, etc. First and foremost, glossy thread adhesives have a bright and shiny surface, which are often higher in standard when compared with matt thread adhesives. Secondly, the color of thread adhesives should be uniform. That is, color patches should be avoided. Thirdly, the hardness must meet the requirements of use, so it is necessary to identify whether the hardness of thread adhesives meets the appropriate value. Fourth, the flexibility of thread adhesives should not be too large, otherwise it will cause wrinkles on the fabric. Fifth, oil absorption is also important, which can affect the dyeing and processing process of thread adhesives.
The chemical properties of thread adhesives are those that reflect the bonding performance of the material, such as durability, adhesion, hydrolysis resistance, washing fastness and thermal stability, etc. Durability is the most fundamental indicator of adhesive performance. If the durability of thread adhesives is not strong enough, it will cause the seam to be easily pulled off. Adhesion is another important factor, and it should be measured before and after processing. Furthermore, hydrolytic resistance is usually measured in a high temperature and pressure environment. Washing fastness is an indispensable indicator, which reflects the ability of thread adhesives to resist commercial detergent. In addition, thermal stability is also an important indicator, which measures the ability of thread adhesives to resist high temperatures or strong acid and alkali.
It is important to remember that when testing the performance of thread adhesives, the physical and chemical indicators must be strictly monitored in order to guarantee the quality of the materials. By doing so, the original performance of thread adhesives can be maintained, so that the production quality of fabrics can reach the optimal level. Quality control of thread adhesives is necessary to guarantee the consistent quality of the fabrics produced.
By testing the physical and chemical indicators of thread adhesives, it becomes increasingly important for manufacturers in the industry to comply with standards and to ensure the quality of their materials. Quality control of thread adhesives is vital to meet customer demands, and it is essential for manufacturers to have the proper understanding of its physical and chemical properties. By keeping these test results in mind, the industry can guarantee the highest quality thread adhesives, and guarantee the successful production of fabrics.
