Silk, a natural protein fiber, is widely used in the textile industry and biomedical materials for its excellent properties. However, its application in some fields is seriously restricted due to its poor anti-wrinkle behavior. In this study, 2,4,6-trichloropyrimidine (TLP) was used in the production of anti-wrinkle silk fabrics. The optimum finishing conditions were as follows: 3-g/L 2,4,6-trichloropyrimidine, 6-g/L NaHCO, 8-g/L NaSO, finishing temperature of 65 °C, and finishing time of 40 min. The crease recovery angle of the finished fabric is 16-20% higher than the unfinished fabric, and the finishing process has a small effect on the whiteness of silk while achieving some degree of washing resistance. The morphology and chemical structures of the finished silk fabric were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy. The K/S value of the finished silk fabric dyed with reactive dyes increased compared with the silk fabric only dyed, indicating that the dyeability of the finished fabric was improved. This technology provides a new method for fabricating silk color crease-resistant fabrics.
丝绸是一种天然蛋白质纤维，因其优异的性能而广泛应用于纺织工业和生物医学材料领域。然而，由于其抗皱性能较差，在某些领域的应用受到严重限制。在本研究中，2,4,6-三氯嘧啶（TLP）被用于生产抗皱丝绸织物。最佳整理条件如下：2,4,6-三氯嘧啶3 g/L、NaHCO 6 g/L、NaSO 8 g/L，整理温度65℃，整理时间40分钟。整理后织物的折皱回复角比未整理织物高16-20%，且整理过程在实现一定程度的耐洗性的同时，对丝绸白度的影响较小。通过扫描电子显微镜和傅里叶变换红外光谱对整理后的丝绸织物的形态和化学结构进行了表征。与仅染色的丝绸织物相比，用活性染料染色的整理后丝绸织物的K/S值增加，表明整理后织物的染色性能得到改善。该技术为制备丝绸彩色抗皱织物提供了一种新方法。
