Problems solved by technology

However, cotton fiber is a flammable fiber, which is very easy to cause fire. Therefore, it is of great significance to carry out flame-retardant finishing on it.
For the durable flame retardant of cotton fabrics, the organophosphorus flame retardant Pyrovatex CP has the best application effect. Its process is simple, its flame retardant and washable are good, and it feels soft, but there is a problem of formaldehyde release in the fabric after finishing.

Abstract

The invention relates to the technical field of semi-durable flame-retardant finishing of cotton fabrics, and provides a semi-durable flame-retardant finishing solution for cotton fabrics and a finishing method for cotton fabrics based on the prepared finishing solution. The flame retardant involved in the present invention has a simple synthesis process, contains phosphorus and nitrogen at the same time, has a synergistic effect, and uses hydroxyl as a reactive group, which can undergo cross-linking reactions with polycarboxylic acids, and the synthesized flame retardant, polycarboxylic acid and catalyst sodium hypophosphite compounded into a finishing solution, which is applied to cotton textiles by the finishing method of padding and baking, and cotton fabrics with semi-durable flame-retardant effects can be obtained; the involved flame-retardant finishing solution uses polycarboxylic acid as the Formaldehyde will not be generated during use; the compounding and finishing methods of the flame retardant finishing liquid involved are simple and easy, and no special equipment is required; when the amount of flame retardant is 20%, it can meet the requirements of vertical combustion; it has Good durability, after washing several times, it still has good flame retardant performance, which can meet the semi-durable flame retardant requirements.

Description

Preparation of semi-durable flame retardant finishing liquid for cotton fabric and finishing method of cotton fabric technical field The present invention relates to the semi-durable flame retardant finishing technical field of cotton fabric, be specifically related to a kind of semi-durable flame retardant for cotton fabric Preparation of flammable finishing liquid and finishing method of cotton fabric. Background technique Cotton fabric is one of the textile products with the longest application time and the widest application range in human history, and has a soft hand feel. Soft, hygroscopic, breathable, comfortable to wear, cheap and other excellent properties, so it is favored by consumers. But cotton fibers For flammable fibers, it is very easy to cause fire, so it is of great significance to carry out flame retardant finishing. Durable flame retardant for cotton fabrics, The organic phosphorus flame retardant Pyrovatex CP has the best application effect, it...
