Embodiment 1
[0016] The invention comprises a polyester-cotton layer or an all-cotton layer or an all-polyester layer in the inner layer, and a flame-retardant layer is arranged outside the inner layer.
[0017] The flame retardant layer is made of nano-scale Mg(OH) 2 , Al(OH) 3 Compatible with acrylic acid emulsion.
[0018] The weight ratio of each material in the flame retardant layer is: nano-scale Mg(OH) 2 60%: Nanoscale Al(OH) 3 25%: smoke suppressant 5%: acrylic acid emulsion 10% mixed.
[0019] The present invention carries out according to the following processing steps:
[0020] 1) Comb the material through high-speed carding machine, open-end spinning machine, and greening machine, and comb it into a base fabric that meets the requirements;
[0021] 2) Use a high-pressure spray gun to spray nano-sized Mg(OH) 2 : Nanoscale Al(OH) 3 : Smoke suppressant: a flame retardant liquid composed of acrylic acid emulsion, which is sprayed on the base fabric with a high-pressure spray...

Abstract
The invention relates to a nanometer environmentally-friendly inflaming retarding cotton yarn filling rope and a manufacturing process thereof. The rope comprises a polyester cotton layer, a pure cotton layer or a pure polyester layer at the inner layer; and an inflaming retarding layer is arranged outside the inner layer. The rope is manufactured through the following process steps: firstly spraying an inflaming retarding liquid on a substrate cloth by using a high pressure spray gun, wherein the inflaming retarding liquid is prepared by nanoscale Mg(OH)2, nanoscale Al(OH)3, smoke suppression agent and acrylic emulsion; adhering the inflaming retarding liquid on the substrate cloth at more than two atmospheres at 150-160 DEG C; drying in vacuum at a high temperature; drying at the temperature of more than 150 DEG C under 1-2 atmospheres; rolling and performing pair twisting in a digital way; and packaging in vacuum so as to manufacture the rope. According to the manufacturing process, the environmentally-friendly nanoscale Mg(OH)2 and Al(OH)3 fire retardant is mixed and dissolved in the acrylic emulsion, and the mixture is coated on the inner surface of waste cotton yarn directly, thereby improving the flame retardant property of an objective product (the oxygen index is more than 40%).
Description
technical field [0001] The invention relates to a nano-environmentally friendly flame-retardant cotton yarn filling rope and a manufacturing process thereof, belonging to a flame-retardant material. Background technique [0002] The flame-retardant layer of the existing filling rope is coated on the surface layer of the base cloth with no nano-scale flame retardant. After testing, its oxygen index is generally not higher than 30%, and its flame-retardant performance needs to be further improved. Contents of the invention [0003] In view of the above defects, the present invention aims to provide a nano-environmentally friendly flame-retardant cotton yarn filling rope and its manufacturing process which can improve the flame-retardant performance of the filling rope. [0004] For this reason, the technical scheme adopted by the present invention is: the present invention comprises a polyester-cotton layer or a full cotton layer or a full polyester layer of the inner layer,...
