Arc protective fabric with single-layer three-dimensional structure and preparation method of arc protective fabric

Abstract

Disclosed is an arc protective fabric with a single-layer three-dimensional structure. The fabric is formed by interweaving warp yarns and weft yarns; the warp yarns comprise two kinds of yarns; the weft yarns also comprise two kinds of yarns; the single-layer fabric forms a three-dimensional structure through a special structure, and the three-dimensional structure can be divided into three layers; and an upper layer is formed by interweaving main body warp yarns and upper layer weft yarns, a middle layer is independently formed by another kind of warp yarns, and a lower layer is formed by interweaving main body warp yarns and lower layer weft yarns. Through special structural design, the fabric forms a single-layer three-dimensional structure, the three-layer structure forms a three-layer effect, due to the formation of the three-dimensional structure, the overall thickness of the fabric is increased, and the arc protection performance of the fabric is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of individual protective textile fabrics, and in particular relates to an arc-proof fabric with a single-layer three-dimensional structure. Background technique

[0002] Arc is a gas discharge phenomenon, the instantaneous spark generated by the current passing through some insulating medium (such as air). The main characteristics of the arc are: rapid occurrence, short duration, high energy generation, surface temperature up to 3000-4000 degrees, and arc center temperature up to 10000 degrees. Every day, thousands of workers are exposed to the danger of electrical arcs. The most common arc hazards are found in the electric power industry, but arc hazards also occur in petrochemical, gas, chemical, water supply companies, oil refineries and other industries. According to statistics, about 1 / 3 of the arc burn accidents occurred in the distribution network, 90% of the accidents occurred at a low voltage not ...

Embodiment

[0030] A single-layer three-dimensional arc-proof fabric of the present invention is formed by interweaving warp yarns and weft yarns. There are two types of warp yarns and two types of weft yarns.

[0031] Two further warp yarns, one for the main body yarn and one for the middle layer yarn. The main warp yarn is a blended yarn, and the yarn contains 50% flame-retardant viscose fiber, 30% aramid 1313 fiber, 10% acrylic fiber, and 10% nylon fiber; the middle layer warp yarn is 100% polyimide filament.

[0032] Further two kinds of weft yarns, one is the upper layer weft yarn, and the other is the lower layer weft yarn. The upper weft yarn is a blended yarn, the yarn contains 50% flame-retardant viscose fiber, 20% aramid 1313 fiber, 10% aramid 1414, 10% acrylic fiber, 5% nylon fiber; the lower weft yarn is also a blended yarn, The yarn contains 70% flame retardant viscose fiber, 25% aramid 1313 fiber, 5% aramid 1414 fiber.

[0033] Further, the weave structure of the fabric is...
