Abstract

The invention relates to a noniron finishing crosslinking reaction buffering agent and an application thereof. The buffering agent is formed by combining one or more of 1,4-diazabicyclo[2,2,2]octane, 1,8-diazabicyclo[5,4,0]undec-7-ene and ammonium hydroxide. The noniron finishing crosslinking reaction buffering agent is added to a noniron finishing solution containing a crosslinking agent, a catalyst and a softener and plays a role in buffering the Lewis acid catalyst at the temperature lower than 130 DEG C, the degree of reaction of the crosslinking agent with cellulose is obviously decreased, the buffering agent can be applied to a noniron delayed-curing reaction system, the storage stability of a sensitized fabric is improved, and the final noniron effect is slightly affected.

Description

technical field [0001] The invention belongs to the field of printing and dyeing auxiliaries and applications thereof, in particular to a non-ironing finishing crosslinking reaction buffer and application thereof. Background technique [0002] The U.S. Patent Publication No. US2,974,432 proposes a delayed baking processing method and has been authorized. The delayed baking processing method refers to applying non-ironing finishing liquid on the fabric by padding and drying to obtain a sensitized fabric, which is stored and transported to the garment factory at low temperature, and then ironed, pressed and baked after the garment is made. Allows cross-linking reactions to occur, resulting in non-iron products with durable pressing effects. This method has simple process and low cost, and has been widely used. [0003] With the wide application of non-ironing delayed baking processing methods, improving the storage stability of sensitized fabrics within a certain temperature...
