Embodiment 1

[0052] Preparation of fluorescent flame-retardant multifunctional double-layer fabric:

[0053] Step 1, select the raw material fiber: select dyeable flame-retardant polyester filament with a yarn count of 150D for the surface layer, accounting for 40%, and use infusible aramid blended yarn for the inner layer, accounting for 60%. The specific proportion of the inner layer is 93% of aramid fiber 1313, 5% of aramid fiber 1414, and 2% of conductive fiber.

[0054] After fully mixing the fibers required for the inner layer above, pretreatment, cotton cleaning, carding, drawing, roving, spun yarn, and winding are sequentially performed to obtain a yarn count of 55 S / 2 Aramid 1313 / 1414 / Conductive Fiber 93 / 5 / 2 blended yarn. Among them, the cylinder speed is 330r / min, the licker-in speed is 750r / min, and the doffer speed is 38r / min. The total draft of the pre-merging is 6.8 times, and the draft of the back zone is 1.97 times; the total draft of the blending is 8.6 times, and the d...

Embodiment 2

[0060] Preparation of fluorescent flame-retardant multifunctional double-layer fabric:

[0061] Step 1, select the raw material fiber: the surface layer is made of 175D dyeable flame-retardant polyester filament, accounting for 46%, and the inner layer is made of infusible aramid blended yarn, accounting for 54%. The specific proportion of the inner layer is 90% of aramid fiber 1313, 8% of aramid fiber 1414, and 2% of conductive fiber.

[0062] After fully mixing the raw materials required for the above inner layer, pretreatment, cotton cleaning, carding, drawing, roving, spun yarn, and winding are sequentially performed to obtain a yarn count of 40 S / 2 Aramid 1313 / 1414 / Conductive Fiber 90 / 8 / 2 blended yarn. Among them, the cylinder speed is 330r / min, the licker-in speed is 750r / min, and the doffer speed is 38r / min. The total draft of the pre-merging is 6.8 times, and the draft of the back zone is 1.97 times; the total draft of the blending is 8.6 times, and the draft of the...

Embodiment 3

[0068] Preparation of fluorescent flame-retardant multifunctional double-layer fabric:

[0069] Step 1, select raw material fibers: use 200D dyeable flame-retardant polyester filaments for the surface layer, accounting for 42%, and use infusible aramid blended yarns for the inner layer, accounting for 58%. The specific proportion of the inner layer is 88% of aramid fiber 1313, 9% of aramid fiber 1414, and 3% of conductive fiber.

[0070] After fully mixing the fibers required for the inner layer above, pretreatment, cotton cleaning, carding, drawing, roving, spun yarn, and winding are sequentially performed to obtain a yarn count of 25 S / 2 Aramid 1313 / 1414 / Conductive Fiber 88 / 9 / 3 blended yarn. Among them, the cylinder speed is 330r / min, the licker-in speed is 750r / min, and the doffer speed is 38r / min. The total draft of the pre-merging is 6.8 times, and the draft of the back zone is 1.97 times; the total draft of the blending is 8.6 times, and the draft of the back zone is ...

Abstract

The invention discloses a fluorescent flame-retardant multi-functional double-layer fabric. The surface layer is woven from flame-retardant yarns that can be dyed in fluorescent colors, and the inner layer is woven from flame-retardant yarns that are non-melting and non-dyeable in fluorescent colors. The warp yarns of the inner layer are lifted and the weft yarns of the outer layer are interwoven to form a stitching structure, so that the two layers of fabrics are connected together. The preparation method is as follows: the warp yarn of the inner layer is lifted and the weft yarn of the surface layer is interwoven to form a joint structure, so that the two layers of fabrics are connected together, and then dyeing is carried out to obtain a fluorescent flame-retardant multi-functional double-layer fabric; wherein, the two-layer fabric The specific weaving method of connecting together is that when putting into the outer weft weaving surface layer, the inner warp must all sink in the lower part of the shed and not interweave with the outer weft; intertwined. The double-layer fabric of the invention has various spacings and can be used to make protective clothing in various fields.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a fluorescent flame-retardant multifunctional double-layer fabric, and also relates to a preparation method of the fluorescent flame-retardant multifunctional double-layer fabric. Background technique [0002] With the continuous breakthrough of new materials and new technologies in my country, the safety technology of industrial textiles is developing towards internationalization, serialization, and comprehensive and multiple performance requirements. The development of safety protective clothing must realize the protection from a single risk factor to The comprehensive protection of multiple risk factors, therefore, the development of protective fabrics with multiple functions conforms to the development of my country's economy, and is of great significance to improving the personal safety protection capabilities of our country. [0003] For some special working env...
