Embodiment 1

[0013] A flame-retardant knitted fabric, the warp of the fabric is DTY 150D / 48F, and the weft is ATY 320D / 96F;

[0014] The fabric is soaked in an impregnation solution containing 40% composite flame retardant at 75°C for 6 hours, and then kept at 160°C for 7 hours after taking it out;

[0015] The composite flame retardant is prepared by the following method: 3 parts of carboxymethyl cellulose, 5 parts of vinyl trimethoxysilane, 9 parts of tetrakis hydroxymethyl phosphine chloride, 2 parts of phosphite, 4 parts of ethyl trimethoxy Ethoxysilane is mixed, and then 8 parts of cyclic phosphonate and 7 parts of molybdenum trioxide are slowly added at the same time, and the feeding is completed within 10 minutes, and the mixing is continued for 15 minutes to obtain a composite flame retardant.

Embodiment 2

[0017] A flame-retardant knitted fabric, the warp of the fabric is DTY 150D / 48F, and the weft is ATY 320D / 96F;

[0018] The fabric is immersed in an impregnating solution containing 35-40% composite flame retardant at 70-75°C for 5-6 hours, and after taking it out, it is kept at a constant temperature of 155-160°C for 5-7 hours;

[0019] The composite flame retardant is prepared by the following method: 2 parts of carboxymethyl cellulose, 4 parts of vinyl trimethoxysilane, 8 parts of tetrakis hydroxymethyl phosphine chloride, 1 part of phosphite, 3 parts of ethyl trimethoxysilane Ethoxysilane is mixed, and then 7 parts of cyclic phosphonate and 6 parts of molybdenum trioxide are slowly added at the same time, and the feeding is completed within 8 minutes, and the mixing is continued for 10 minutes to obtain a composite flame retardant.

Embodiment 3

[0021] A flame-retardant knitted fabric, the warp of the fabric is DTY 150D / 48F, and the weft is ATY 320D / 96F;

[0022] The fabric is immersed in an impregnating solution containing 37% composite flame retardant at 73°C for 5.5 hours, and after taking it out, keep the temperature at 158°C for 6 hours;

[0023] The composite flame retardant is prepared by the following method: 2.3 parts of carboxymethyl cellulose, 4.5 parts of vinyl trimethoxysilane, 8.9 parts of tetrakis hydroxymethyl phosphine chloride, 1.2 parts of phosphite, 3.4 parts of ethyl trimethoxysilane Ethoxysilane was mixed, and then 7.8 parts of cyclic phosphonate and 6.7 parts of molybdenum trioxide were slowly added at the same time, and the feeding was completed within 9 minutes, and the mixing was continued for 14 minutes to obtain a composite flame retardant.

[0024] The flame retardant slice test report of the flame retardant knitted fabric of the present invention is shown in Table 1.

Abstract

The invention discloses a flame-retardant knitted fabric. The warp of the fabric is DTY150D/48F, and the weft of the fabric is ATY320D/96F; the fabric is soaked in steeping liquid containing 35%-40% composite finishing agent at the temperature ranging from 70 DEG C to 75 DEG C for five hours to six hours and then is placed at the constant temperature ranging from 155 DEG C to 160 DEG C for five hours to seven hours after being taken out. The composite finishing agent is prepared with the following methods that 2 parts to 3 parts of carboxymethyl cellulose, 4 parts to 5 parts of vinyl trimethoxy silane, 8 parts to 9 parts of tetrakis hydroxymethyl phosphonium chloride, 1 part to 2 parts of phosphorous ester and three parts to four parts of triethoxy ethyl silane are mixed, then, 7 parts to 8 parts of cyclic phosphonate ester and 6 parts to 7 parts of molybdenum trioxide are synchronously and slowly added, material feeding is completed within eight minutes to ten minutes, continuous mixing lasts for ten minutes to fifteen minutes, and the composite flame-retardant agent is prepared. The flame-retardant knitted fabric has excellent flame-retardant performance.

Description

technical field [0001] The invention relates to flame-retardant knitted fabrics. Background technique [0002] The flame retardant effect of the current knitted fabrics is not very ideal, and the fabrics with better flame retardant properties are not very comfortable to the touch. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant knitted fabric, which is comfortable to the touch and has excellent flame-retardant properties. [0004] In order to achieve the above purpose, the technical solution of the present invention is to design a flame-retardant knitted fabric, the warp of the fabric is DTY 150D / 48F, and the weft is ATY 320D / 96F; [0005] The fabric is immersed in an impregnating solution containing 35-40% composite flame retardant at 70-75°C for 5-6 hours, and after taking it out, it is kept at a constant temperature of 155-160°C for 5-7 hours; [0006] The composite flame retardant is prepared by the following met...
