Abstract

The invention discloses an inflaming retarding system and a preparation method of an inflaming-retarding real silk. The inflaming retarding system is a phosphorus-silicon collaborative system, wherein a phosphorus component is methacryloyloxyethyl dimethyl phosphate and a silicon component is a vinyl silane coupling agent. The preparation method comprises the following steps of: preparing an inflaming-retarding working solution and adjusting the pH (Potential of Hydrogen) value of the working solution to 4-4.5; immersing a real silk textile into the inflaming-retarding working solution, and heating the real silk textile at 80-85 DEG C for 10-60 minutes; and washing the real silk textile by water and drying the real silk textile to obtain the inflaming-retarding real silk. A fire retardant provided by the invention is durable, and no formaldehyde is released in an inflaming retarding and sorting process; and the smoke amount of the real silk textile in a combustion process is as low as required.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, and in particular relates to a method for low-smoke and flame-retardant finishing of textiles, especially silk. Background technique [0002] Fires caused by textiles account for approximately 20 percent of residential fires, but account for 50 percent of all fire deaths. The cause of death is mostly due to the high concentration of smoke generated by the burning of materials in the fire, which affects visibility and causes suffocation. Therefore, legislation in various countries puts forward corresponding flame-retardant performance requirements for textiles used in different fields, and while using flame-retardant materials, reducing the amount of smoke generated when the materials are burned is particularly important to reduce the fire fatality rate. [0003] Silk fiber, known as the "Fiber Queen", is widely used in clothing and decorative materials due to its health care, comfort, ...
