The invention discloses a method for evaluating the melting rate of a hot-melt adhesive. Melting indexes of a hot-melt adhesive product in different time periods are measured, melting rates of the hot-melt adhesive product in all the time periods are determined, and when the melting rate is higher than or equal to 80%, the practical production requirement is met. Then, retention time of the hot-melt adhesive product in a drying oven during practical production is determined according to the melting rate, and the better suggested production rate is determined finally. The performance index, namely, the melting rate, of the hot-melt adhesive product can be directly measured with the method, the better practical production rate can be effectively guided and provided, and traditional time-consuming and effort-consuming repeated adjustment schemes are not required to be adopted, so that the production efficiency is greatly improved.
