Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment will be described in detail with reference to fig. 1 and 2. The flame-retardant nylon fabric comprises nylon base cloth 1 and a flame-retardant coating 2 compounded with the nylon base cloth 1. The nylon base cloth 1 is formed by interweaving warp yarns and weft yarns. The warp yarn is 20 +/-3D/1F semi-gloss nylon filament, and the weft yarn is 100 +/-5D/36F semi-gloss nylon filament. The 20D/1F semi-gloss nylon filaments used in this example were found to be 19D. The weft yarn was 100D/36F semi-gloss nylon filament, which was found to be 95D.

The warp yarns include a first warp yarn 11, a second warp yarn 12, a third warp yarn 13, a fourth warp yarn 14 and a fifth warp yarn 15. The weft yarns include first weft yarn 21, second weft yarn 22, third weft yarn 23, fourth weft yarn 24, and fifth weft yarn 25. The weft yarns comprise a first weft yarn, a second weft yarn, a third weft yarn, a fourth weft yarn and a fifth weft yarn; taking the weft as a reference, the sinking and floating rule of the first warp 11 is floating-sinking, the sinking and floating rule of the second warp 12 is sinking-floating-sinking, and the sinking and floating rule of the third warp 13 is sinking-floating-sinking; the sinking and floating rule of the fourth warp 14 is sinking-floating; the sinking and floating rule of the fifth warp 15 is sinking-floating-sinking.

In this example, a 24-gauge reed was used for weaving, with 5 warp yarns per dent, a warp yarn density of 350 yarns per inch, and a weft yarn density of 100 yarns per inch.

The embodiment also relates to a flame-retardant nylon fabric, which is characterized in that the woven nylon base fabric 1 is not dyed or dyed to be in the color of a card, then an organic silicon waterproof agent is used for waterproof treatment, waterproof layers are formed on the upper surface and the lower surface of the nylon base fabric, and then a waterproof flame-retardant coating is compounded on one side after the waterproof treatment.

The waterproof flame-retardant coating is prepared by adding an organic silicon waterproof agent into slurry used for flame-retardant coating, so that the coating has waterproof and flame-retardant effects.

The dyed nylon base fabric according to the present example was subjected to color fastness detection, and through detection, the original color change was GS4 grade, the cotton staining was GS5 grade, and the wool staining was GS4 grade. The breaking strength of the warp direction and the weft direction is not less than 113KG, the warp direction is 132KG after the test, and the weft direction is 118 KG. The waterproof grade of the nylon base cloth is 4 grade.

The flame-retardant nylon fabric with the waterproof flame-retardant coating is tested, the weight of the coating is 20% of the surface density of the nylon base fabric, and the surface density of the flame-retardant nylon fabric after coating is 100 grams per square meter. The flame-retardant nylon fabric is subjected to a waterproof test, the height is 15.5cm, the diameter is 20.5cm, and the bowl-shaped fabric is hung in a water-filled manner, so that no permeation is required within 1 hour. The flame-retardant nylon fabric related to the embodiment has no leakage within 2 hours.

When the flame-retardant fabric is subjected to a waterproof test, the warp density and weft density of the fabric have the influence on the waterproof performance by the coating. In order to improve the weaving efficiency, the warp and weft density, especially the weft density, is reduced, so that the warp and weft yarns have larger gaps, namely, the tightness is reduced. The amount of sizing agent used for the flame-retardant coating needs to be increased, which affects the drying of the subsequent coating treatment and affects the hand feeling. If the weft density is increased, the tightness of the base fabric can be increased, when the water seepage effect is achieved, the using amount of the flame-retardant coating slurry can be reduced, but the increase of the weft density can cause the weaving difficulty and reduce the weaving speed. The weaving difficulty and the coating finishing difficulty are combined, the hand feeling problem in use is considered, the density of the warp yarn is 350 pieces per inch, the density of the weft yarn is 100 pieces per inch, the weight of the flame-retardant coating after being dried accounts for 20 percent of the weight of the base fabric, and the weaving difficulty, the coating treatment, the hand feeling and the result of the combined consideration are considered.

And (4) carrying out flame retardant property test according to ASTM-D6413, and adopting a vertical combustion method to extinguish in 2S after 12S ignition. While the flame retardant nylon fabric according to the present example was extinguished within 1S.

Example two

With reference to fig. 3, for the flame retardant nylon fabric according to the present embodiment, an ultraviolet-proof layer 3 is disposed on the other side of the nylon base fabric 1.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
