Abstract

The invention belongs to the technical field of fiber filament structures, and particularly relates to a composite polyester filament yarn and a processing method thereof. A purpose of effectively processing and producing the composite polyester filament yarn is achieved by coating a bonding layer on a polyester filament yarn body and then coating a flame-retardant layer. The three-layer compositepolyester filament yarn is stable in structure, a crosslinked structure of the flame-retardant layer and the bonding layer is large in strength, the flame-retardant layer is not prone to falling, theflame-retardant layer is good in flame retardant effect, the processing method is reasonable and efficient, a laminating mode of an upper roller and a lower roller is simple and effective, and finally an advantage of lasting flame retardant effect of the composite polyester filament yarn is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fiber filament structure, and in particular relates to a composite polyester filament and a processing method thereof. Background technique [0002] Composite polyester filament refers to a multi-layered polyester filament with additional functions such as composite flame retardant on the basis of polyester filament. Its structure generally only includes the main body of the filament and the flame retardant layer. Some filaments have a two-layer structure with a flame-retardant layer on the main body, and there is a problem that the flame-retardant layer is easy to fall off. Therefore, a new type of flame-retardant composite polyester filament with high composite strength and good flame-retardant effect is urgently needed in the market. [0003] The patent announcement number is CN 205115687U, and the Chinese utility model patent with the announcement date of 2016.03.30 discloses a flame-retardant and bre...
