Abstract

The invention discloses a preparation method of flame-retarding cotton fabric. The preparation method of the flame-retarding cotton fabric comprises pre-processing of pure cotton fabric, wherein a silane coupling agent and a sodium hypophosphite solution are mixed to prepare a pre-processing solution, the pH value is regulated to 4-5 with acetic acid, the pure cotton fabric is added into the pre-processing solution, is heated and is then taken out to be baked; and flame-retarding finishing of the pure cotton fabric: a water-alcohol mixed solution containing ammonium dihydrogen phosphate, EDC and NHS is prepared, and the pre-processed fabric is immersed in the water-alcohol mixed solution, is treated at the temperature of 4 DEG C and is then taken out to be washed and dried. According to the preparation method of flame-retarding cotton fabric, phosphoric acid and polyphosphoric acid released after the finishing agent is heated react with hydroxyl on 6# carbon atoms in advance for dehydration, and then an elimination reaction occurs to form C=C bonds to promote the formation of a heat insulation and oxygen insulation coke layer, so that the generation of levoglucose is fundamentallyprevented.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant cotton fabrics, and in particular relates to a preparation method of flame-retardant cotton fabrics. Background technique [0002] Cotton fabrics are popular for their high quality and low price, and are widely used in daily wear and building materials. However, because the main component of cotton fabric is flammable cellulose, it is subject to greater restrictions in the application process, which limits the application range of cotton fabric. The combustion of cotton fabric is due to thermal cracking and oxidative cracking in the air, forming L-glucose monomer and producing flammable gas. The heat released during the combustion process further decomposes the cellulose, forming a cycle process until the fabric is completely burned. burn. [0003] In the present invention, the silane coupling agent KH550 is firstly used to pretreat the pure cotton fabric by heating and impregnating; the...
