The weight content of metal fiber in the blended yarn is 75%, the weight content of aramid fiber 1414 is 10%, the weight content of aramid fiber 1313 is 10%, and the weight content of nylon fiber is 5%. The linear density of the blended yarn was 28.1tex×2. The fabric structure is 1 / 1 plain weave, and the mass per unit area of ​​gray cloth is 230g / m 2 .

[0040] The above-mentioned high-voltage electrostatic fabric adopts the following weaving process, and the steps are as follows:

[0041] (1) Spinning: Metal fiber, aramid 1313 fiber, aramid 1414 fiber and nylon fiber are used as raw materials, followed by cleaning→carding→drawing→roving→spinning→winding→doubling→twisting→steaming The yarn is made into a ble...

Embodiment 2

[0051] The high-voltage electrostatic protection fabric in this embodiment is formed by interweaving warp and weft yarns, and the warp and weft yarns are all blended yarns of metal fibers (stainless steel fibers), aramid 1313 fibers and aramid 1414 fibers. The metal fiber weight content in the blended yarn is 30%, the aramid fiber 1414 fiber weight content is 35%, and the aramid fiber 1313 fiber weight content is 35%. The linear density of the blended yarn was 14.7 tex x 2. The fabric structure is 2 / 1 twill weave, and the mass per unit area of ​​gray fabric is 100g / m 2 .

Abstract

The invention discloses high-voltage electrostatic protection shell fabric formed by interweaving of warps and wefts. Both of the warps and wefts are blend fibers comprising 30-80% of metallic fibers and 20-70% of aramid fibers; further, both of the warps and wefts are blend fibers comprising 30-79% of metallic fibers, 20-69% of aramid fibers and not more than 15% of polyamide fibers, wherein the aramid fibers include at least one kind of 1313 fibers and 1414 fibers; when the aramid fibers include both of the 1313 fibers and the 1414 fibers, the 1313 fibers and the 1414 fibers can be in an optional proportion. The manufacturing technology of the high-voltage electrostatic protection shell fabric includes the steps of preparing blended yarn from fibrous raw materials, warping, sleying, weaving on a rapier loom according to the technology of 'short back beam, small tension and small opening', burling, finishing and carrying out finished product inspection. The high-voltage electrostatic protection shell fabric has the advantages of high strength, high wear resistance, high shielding performance, low resistance, fire resistance and dimensional stability.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a high-voltage electrostatic protection fabric, and also relates to a manufacturing process of the fabric. Background technique [0002] Under the condition of ground potential operation in the electric power industry, a sufficient safety distance must be ensured between personnel and charged objects (including adjacent phase high-voltage conductors). In the past, due to the consideration of safety and operating equipment, under normal circumstances, electrical work was performed with power off. However, power outage operations will cause large-scale power outages and cause large economic losses. At the same time, adequate preparations must be made when power outages and power transmissions occur, which increases the human and material costs of the power industry and some other losses. At present, more and more electric power departments begin to use live work, so t...
