[PROBLEMS] Conventionally, methods using resin processing chemicals, cyanuric chloride or dichlorotriazine compounds, etc., are known as methods for imparting a pleasant texture and anti-pilling properties to natural fiber materials. There are problems such as poor quality, unstable quality, and insufficient processing effect. [Means for Solving the Problems] As a result of solving the above-mentioned problems and promoting the practical application of a modification process for natural fiber materials that are kind to the skin, the present inventors cross-linked animal and plant proteins with alkali using polyhalogenopyrimidine compounds. It was found that a natural fiber material excellent in texture, wearing comfort, anti-pilling property, form stability, repeated washing durability and the like can be provided by combining and treating with weak acid as necessary.
