Description

Application of sodium cyclamate in textile functional finishing
Technical Field

Background
With the continuous development and progress of science and technology and economy, the requirements of people on different functional textiles are increasing day by day, the traditional finishing technology needs to adapt to new development, and the textile function finishing technology is urgently needed to be innovated. According to the requirements of different forms of daily life, different textiles can be subjected to various finishing processes, such as bleaching, felting prevention finishing, fuzzing and pilling prevention finishing, non-ironing finishing and the like. These finishing processes can cause great strength damage to the textile, and in actual production, yarns and fabrics with great strength are usually used, and damaged parts of the textile are reserved so that the finished fabric can reach the standard of clothing. However, the treatment method has the disadvantages of large limitation, high requirement on cotton fiber, high defective rate and increased production cost to a certain extent.
In order to reduce the damage of the chemical auxiliary agent to the fiber during finishing, a strong protective agent is sometimes added during production. At present, most of common strong protective agents in the market are nonionic polyethylene emulsions, a flexible and smooth film can be formed on the surface of a fiber, and the tearing strength and the wear resistance of a fabric are improved. In each study at present: the fiber protective agents PF3, TF-652, KSA and the like are added in the non-ironing finishing by scholars, and the introduction of the protective agents reduces the strength loss, but also influences the finishing effect of the fabric; the fiber protective agent DTP is used in the finishing of the cotton fabric resin, so that the tearing strength and the recovery performance of the fabric are improved, but the breaking strength of the fabric is reduced; different protective agents 3001, CHT and JD-W are introduced in mercerized wool bleaching, so that the strength retention rate is only improved by 1.84%, and the strength protection effect is not outstanding; in the oxidation degumming of ramie, a fiber protective agent danthron or a slow-release type alkali source is introduced, so that the damage to cellulose can be reduced, the yield of fiber can be improved, but the two substances have poor solubility, are in a suspended sol state in a system and are not easy to clean, and the danthron has micro toxicity and a certain color and is difficult to apply to actual production and processing.
The comprehensive research of various processing and finishing of the textiles shows that the existing strong protective agent has low universality and unsatisfactory effect, and the protective agents selected in different processing treatments are different; few protective agents with acceptable effects also have defects, or affect other physical and chemical properties of textiles, or have higher application difficulty. Therefore, the problem to be solved is to find a strong protective agent which can reduce the damage to the fiber in various processing and finishing processes, has high universality and excellent effect.
