Description

Technical Field

[0001] The utility model belongs to the field of arc fabrics, and in particular relates to a multifunctional arc fabric with a double-sided structure. Background Art

[0002] Arc-proof clothing is a special type of protective clothing designed to prevent and protect people from electric arc damage. In industries such as electricity, petrochemicals, and metallurgy, electric arcs are a serious work hazard, making the use of arc-proof clothing a necessary safety measure. The materials used in arc-proof clothing are crucial. Generally speaking, arc-proof clothing is made of materials that are non-flammable and heat-resistant, such as flame-retardant fabrics, flame-retardant fibers, and fire-retardant coatings. These materials are resistant to high temperatures, fires, and flames, effectively mitigating the damage caused by electric arcs to the human body.

[0003] Arc-flash protective clothing is primarily made of flame-retardant acrylic and aramid fabrics. The superior performance of these high-end fabrics lies primarily in the thermal expansion of acrylic and the thermal insulation, high strength, and flame-retardant properties of para-aramid. However, due to the unique characteristics of para-aramid, it exhibits poor lightfastness and is prone to color change. Maintaining high visibility in arc-flash protective clothing is crucial for high-risk and low-visibility work environments. Furthermore, the design of arc-flash protective clothing also considers human comfort and freedom of movement. In work environments, workers are required to wear arc-flash protective clothing for extended periods of time. Rough fabrics can affect the operator's wearing experience and increase discomfort during work. Summary of the Invention

[0004] In response to the above problems and technical needs, the utility model provides a multifunctional arc fabric with a double-sided structure. This fabric connects and integrates the various functional layers required for arc fabric into one through weaving, so that the fabric not only has flame retardant, arc proof, anti-static and other properties, but also has high visibility and comfortable feel.

[0006] Furthermore, the ratio of the number of the surface warp A yarns to the number of the inner warp B yarns is 3:2, and the ratio of the number of the surface weft A yarns to the number of the inner weft B yarns is 7:6.

[0007] Furthermore, the arrangement order of the surface warp A yarn and the inner warp B yarn is AABAB, 8 groups of warp yarns arranged in the same manner constitute a cycle, and one cycle consists of 40 yarns.

[0008] Furthermore, the arrangement order of the surface weft A yarn and the inner weft B yarn is ABABABABAABAB AB ABABABAABABABABABABAA BABABABABAABABAB, and 52 yarns constitute one cycle.

[0009] Preferably, the yarn A has a 150D specification and is twisted with a twist coefficient of 600 twists / m.

[0011] Beneficial effects of the utility model:

[0012] 1) This fabric is formed by interweaving the surface tissue and the inner tissue. The surface tissue and the inner tissue respectively assume different functional layers. The two overlapping layers of fabric formed by interweaving are actually a whole, rather than two separate parts. Therefore, the fabric is compact and wear-resistant, with stronger firmness and strength, and is suitable for use in harsh arc environments;

[0013] 2) The surface fabric, A yarn, is made of flame-retardant polyester or flame-retardant nylon filament, dyed into a visible fluorescent orange or fluorescent yellow. The fluorescent color is highly visible, visually indicating the wearer's presence. Flame-retardant polyester or flame-retardant nylon filament also has high color fastness and is not easily discolored or faded in high-temperature environments. Furthermore, the twisted A yarn imparts a smooth surface, high strength, and resistance to snagging to the final fabric, while the jacquard weave enhances the wear resistance of the final fabric.

[0014] 3) The inner layer of the fabric, B yarn, is a short-staple yarn made by blending flame-retardant acrylic, para-aramid, long-staple cotton and anti-static fiber materials. The flame-retardant acrylic and para-aramid have flame retardant and arc-proof properties, the anti-static fiber has anti-static properties, and the long-staple cotton material provides the fabric with a more comfortable and soft feel and breathability, which can improve the wearing experience and enhance wearing comfort. The inner layer also uses jacquard structure, which can give the fabric high strength, less fuzz, a tight fabric and higher wear resistance. BRIEF DESCRIPTION OF THE DRAWINGS
