Problems solved by technology

In the flame retardant and waterproof functional finishing agent, components with flame retardant functions such as silicon and phosphorus are introduced at the same time. Specifically, phosphorus is introduced into the polysiloxane segment to solve the problem of uneven dispersion of functional components in the system. Difficult to finish at one time, so as to avoid the mutual exclusion of waterproof performance and flame-retardant performance, and achieve the purpose of one-bath finishing with waterproof and flame-retardant functions

Abstract

The invention discloses a method for preparing a flame-retardant and waterproof fabric. Step 1 configures a flame-retardant and waterproof functional finishing liquid according to the process prescription; Step 2 immerses the fabric in the flame-retardant and waterproof functional finishing liquid and squeezes the liquid; bake. The flame-retardant and waterproof functional finishing liquid is composed of a flame-retardant and waterproof functional finishing agent and water. The phosphorus-containing polysiloxane flame-retardant and waterproof finishing agent prepared by the invention effectively combines phosphorus and polysiloxane to integrate the flame-retardant and waterproof functions together to form polysiloxane with excellent flame-retardant and waterproof properties Flame-retardant and waterproof functional finishing agent, and adopts one-bath finishing process to endow the fabric with flame-retardant and waterproof performance. It solves the problem of uneven dispersion of functional components in the system and difficulty in one-time finishing, thereby avoiding mutual exclusion of waterproof performance and flame-retardant performance, and achieving the purpose of one-bath finishing with waterproof and flame-retardant functions.

Description

technical field [0001] The invention belongs to the field of functional textile fabrics, and in particular relates to a method for preparing flame-retardant and waterproof fabrics. Background technique [0002] Fabric functional finishing is a finishing technology that evenly pads or coats one or several layers of polymer substances on the fabric to endow the fabric with certain characteristics. Through functional finishing, the appearance and style of fabrics can be changed, and many new functions can be added to meet consumers' pursuit of comfort, convenience and functionality of textiles. Therefore, it has received extensive attention at home and abroad, and has gained rapid develop. [0003] Most of the current textile products in our country have good water resistance after finishing, but the air permeability and moisture permeability are generally poor, resulting in the water vapor in the human body not being released in time, giving people an extremely stuffy feeling...
