New Method to Evaluate the Crosslinking Degree of Resin Finishing Agent with Cellulose Using Kjeldahl Method and Arrhenius Formula

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