In anti-wrinkle finishing, the crosslinking degree of fabric is mainly determined by wrinkle recovery angle, stiffness, and viscosity, these indicators can only reflect the finishing effect from a macro perspective, which cannot reflect whether the crosslinking is sufficient, and it is difficult to quantify the crosslinking degree. In this paper, we combined the Kjeldahl method with the Arrhenius formula and proposed a method to analyze the crosslinking degree of dimethyloldihydroxyethyleneurea (two-dimensional (2D) resin) with cotton cellulose during delayed-cure finishing for the first time. The nitrogen content of completed fabrics during storage was measured by the Kjeldahl method, and the reaction rate equation of the 2D resin and cellulose under normal temperature conditions was calculated. The results show that the nitrogen content is more suitable to indicate the crosslinking degree, and the apparent activation energy was 28.271 kJ/mol and the pre-finger factor was 0.622, which indicated that the 2D resin was prone to cross-linking with cotton fabrics during storage. During long-term storage, the relative errors between the calculated and measured values of the nitrogen content were within ±5%, and the accuracy was higher than the traditional evaluation method. The stability of 2D resins during the storage of delayed-curing finishing was also analyzed through this method.

Kjeldahl法和Arrhenius公式评价树脂整理剂与纤维素交联度的新方法。

在抗皱整理中，织物的交联度主要由皱折恢复角，挺度和粘度决定，这些指标只能从宏观的角度反映整理效果，不能反映交联是否充分，难度大。量化交联度。在本文中，我们将凯氏定氮法与Arrhenius公式相结合，首次提出了一种方法来分析延迟固化后二甲基二羟甲基乙烯脲（二维（2D）树脂）与棉纤维素的交联度。通过凯氏定氮法（Kjeldahl method）测量保存过程中成品织物的氮含量，并计算出常温条件下二维树脂与纤维素的反应速率方程。结果表明，氮含量更适合指示交联度，表观活化能为28.271 kJ / mol，预指数为0.622，表明二维树脂易于与棉织物交联。在存储过程中。长期保存过程中，氮含量的计算值与实测值之间的相对误差在±5％以内，准确度高于传统的评估方法。通过这种方法还分析了二维树脂在延迟固化整理剂的储存过程中的稳定性。氮含量的计算值与实测值之间的相对误差在±5％以内，准确度高于传统的评价方法。通过这种方法还分析了二维树脂在延迟固化整理剂的储存过程中的稳定性。氮含量的计算值与实测值之间的相对误差在±5％以内，准确度高于传统的评价方法。通过这种方法还分析了二维树脂在延迟固化整理剂的储存过程中的稳定性。
