Description
Technical Field
The utility model relates to the technical field of protective fabrics, in particular to a fluorescent color flame-retardant antistatic three-layer grid-shaped fabric.
Background
In the working environments of high-temperature roasting, molten metal splashing and the like, operators need to wear protective clothing made of anti-metal melting splashing and anti-static fabrics to protect the safety of the operators. In recent years, the increasing number of safety accidents in production leads people to be more and more aware of the importance of protective clothing, and the reasonable use of the protective clothing can protect the life safety of workers at a critical moment. With the increasing specificity and complexity of production environments, the requirements for protective garments are becoming more and more stringent, and the versatility of protective products has been the direction of research by the relevant technicians. The flame-retardant fireproof fluorescent fabric is a product which is devotedly developed by each country, and has high visual effect while the human body is protected from flame retardance.
The modacrylic has high limited oxygen index, is carbonized without molten drops after combustion, is a good flame retardant material, but has extremely poor fluorescence dyeability, particularly fluorescence orange, and is difficult to overcome at present. However, the polyester yarn has no flame retardant property, is melted in the combustion process and releases a large amount of heat, so that the application of the polyester to flame retardant products needs to strictly control the ratio of the polyester to the products and needs to combine with design patterns to realize the final flame retardant effect of the products.
SUMMERY OF THE UTILITY MODEL
The utility model is developed based on the requirements of high visibility, high safety and the like in a flammable working environment, provides a fluorescent color flame-retardant antistatic three-layer grid-shaped fabric, and the protective clothing prepared by the fabric has the performances of antistatic property, flame retardance, high visibility and the like.
The technical means adopted by the utility model are as follows:

The surface layer is woven by polyester yarns and flame-retardant yarns, 1 line of flame-retardant yarns is added to every 8 lines of polyester yarns in the transverse direction, and 1 line of gaps are formed by tuck processing every 6 lines of polyester yarns in the longitudinal direction, so that the spacing effect is formed visually; this kind of structure sets up when surface fabric meets flame, and horizontal and vertical because the fire-retardant function of fire-retardant yarn can play the cutting to flame, slows down the burning trend of flame to fire-retardant yarn also can absorb partly heat in the combustion process, reduces the combustion heat of flame, forms the first layer protection to the human body. The polyester yarn is dty100D/48f polyester dyed filament; the flame-retardant yarn I is a blended yarn of 60% modacrylic, 38% cotton and 2% conductive fiber, and the yarn count is 40s single yarn;
the middle layer is woven by the flame-retardant yarn II, and plays roles in further flame retardance, heat insulation and polyester molten drop resistance; the second flame-retardant yarn is a 24s single yarn which is blended yarn of 60% of modacrylic, 27% of flame-retardant viscose, 10% of aramid fiber and 3% of conductive fiber; the DTY100D/48f polyester dyed filament on the surface layer releases heat in a large amount and generates molten drops during combustion, and although the 40s modacrylic/cotton/conductive flame-retardant blended yarn on the surface layer plays a certain role in reducing combustion energy in the process of blocking flame, the combustion process can be accelerated theoretically due to the melting and heat release of the polyester during combustion, so that the 40s modacrylic/cotton/conductive flame-retardant blended yarn on the surface layer fabric only can play a certain role in slowing down the combustion and cannot completely block the flame combustion. At the moment, thicker 24s modacrylic/flame-retardant viscose/aramid/conductive fiber blended yarn is selected as the middle padding layer, so that a large amount of combustion heat can be further absorbed in the combustion process, a good flame-retardant function is achieved, and meanwhile, high-heat molten drops generated when the polyester yarn is melted can be prevented from contacting a wearer, and secondary protection is formed for the human body. The application of the high-modulus aramid fiber in the intermediate layer blended yarn effectively improves the yarn strength, so that the padding yarn in the intermediate layer can be more easily woven during weaving, the production work efficiency is improved, and the rejection rate is reduced;
the bottom layer is woven by flame-retardant yarns I; the design of the bottom layer fabric plays roles of inflaming retarding and molten drop blocking once again, ensures that the product can be completely inflaming retarding, and forms a third protection for a human body; the three-layer fabric can basically effectively prevent the fire hazard of flame to human body by the obstruction of the three-layer fabric, and the three-layer structure has two air layers in the middle, so that the air layers can obstruct the heat transfer, have certain effect on flame retardance and ensure that the product has better heat insulation performance;
the surface layer, the middle layer and the bottom layer are integrally woven and formed through a weaving machine;
dyeing the woven and formed grey cloth, specifically dyeing by adopting a cationic dye and an active dye, washing with water, washing with acid, washing with soap, washing with acid, adding a softening agent, and drying, wherein the cationic dye is used for dyeing modacrylic and the active dye is used for dyeing cotton; and further dyeing, namely sequentially carrying out processes of boiling, washing, pickling, cationic dyeing, washing, soaping, color fixing, shaping and the like on the grey cloth to finally obtain a final product with full and rich colors.
Further, the modacrylic had a fiber fineness of 1.7DTEX and a fiber length of 38 mm.
Further, the linear density of the cotton fiber is 1.56-2.12 DTEX, and the fiber length is 25-35 mm.
Further, the conductive fiber had a fiber fineness of 1.6DTEX and a fiber length of 38 mm.
Further, the fiber fineness of the flame-retardant viscose is 1.7DTEX, and the fiber length is 40 mm.
Further, the fiber fineness of the aramid fiber was 1.5DTEX, and the fiber length was 38 mm.
The utility model also provides protective clothing prepared from the fluorescent color flame-retardant antistatic three-layer grid-shaped fabric.
