Embodiment 1

[0031] Both the warp and weft yarns are pure cotton yarns, and the silver-plated yarns are embedded in the fabric with the interval ratio of 1:60 as the silver-plated yarns and ordinary cotton yarns to obtain antistatic fabrics. Soak in L acrylamide monomer solution for 2.5h, then put the fabric into a high-energy electron beam for irradiation after dipping and rolling (roller speed 1m / min, pressure 0.1Mpa), the irradiation dose is 22kGy, After the reaction, the fabric was taken out and washed with deionized water to remove the homopolymer and unreacted graft monomer on the surface of the fabric, and finally dried in an oven to constant weight. The graft rate of the obtained fabric is 11.15%. The vertical burning test shows that the afterburning time and the smoldering time are 4.5s and 4s respectively, and the limiting oxygen index is 29%. Its triboelectric voltage is 934V, and the surface resistivity is 1×10 9 Ω.

Embodiment 2

[0033] Both the warp and weft yarns are made of pure cotton yarns, and the silver-plated yarns are embedded in the fabric with an interval ratio of 1:40 with ordinary cotton yarns to obtain antistatic fabrics. Soak in the acrylamide monomer solution for 2.5h, then put the fabric into a high-energy electron beam for irradiation after dipping and rolling (roller speed 1m / min, pressure 0.1Mpa), the irradiation dose is 43kGy, the reaction After finishing, the fabric is taken out and cleaned with deionized water to remove the homopolymer and unreacted graft monomer on the surface of the fabric, and finally dried in an oven to constant weight. The grafting rate of the resulting fabric is 23.25%. The vertical burning test shows that the afterburning time and the smoldering time are 4s and 3.5s respectively, and the limiting oxygen index is 32%. Its triboelectric voltage is 876V, and its surface resistivity is 4×10 8 Ω.

Embodiment 3

[0035] Both the warp and weft yarns are pure cotton yarns, and the silver-plated yarns are embedded in the fabric with an interval ratio of 1:20 as the silver-plated yarns and ordinary cotton yarns to obtain antistatic fabrics, and then the woven fabrics are woven at a concentration of 2mol / L Soak in the acrylamide monomer solution for 2.5h, then put the fabric into a high-energy electron beam for irradiation after dipping and rolling (roller speed 1m / min, pressure 0.1Mpa), the irradiation dose is 65kGy, the reaction After finishing, the fabric is taken out and cleaned with deionized water to remove the homopolymer and unreacted graft monomer on the surface of the fabric, and finally dried in an oven to constant weight. The grafting rate of the obtained fabric is 11.15%. The vertical burning test shows that the afterburning time and the smoldering time are 3s and 3s respectively, and the limiting oxygen index is 36%. Its triboelectric voltage is 783V, and its surface resistivit...

Abstract

The invention discloses a preparation method of a flame-retardant antistatic fabric. The preparation method comprises the steps: (1) in a process of weaving the fabric, selecting a proper fabric weave structure, weaving antistatic filaments in the fabric in an embedded weaving manner, and reasonably designing the embedded spacing; (2) soaking the fabric obtained from weaving in a grafting monomer solution for 1-3 hours, followed by, taking out the fabric, rolling to remove excess liquid through a padder, wrapping the fabric with a plastic thin film, putting in a self-seal bag, putting the fabric together with the self-seal bag into a high energy electron beam, and irradiating; and (3) after the irradiation is finished, washing the grafted fabric with deionized water, and removing homopolymers and unreacted monomers on the fabric surface; and then putting the fabric after cleaning in a drying oven, and drying for 24 hours to obtain the product. The fabric has good durability, flame retardancy and antistatic properties, and is a fabric having flame-retardant and antistatic double functions.

Description

technical field [0001] The invention discloses a method for preparing a flame-retardant antistatic fabric, which belongs to the technical field of fabric materials. Background technique [0002] With the development of industry, people's understanding of frequent accidents has deepened and their awareness of safety protection has gradually increased. People's requirements for textiles are not limited to the original basic characteristics such as warmth and comfort. People also hope that they have health care, safety, etc. For special functions, fabrics based on a single function can no longer meet the needs of the market, and dual-function fabrics and even multi-functional fabrics have emerged as the times require. Among them, flame retardant and antistatic fabric is one example. It can be used in many occasions such as protective work clothes and interior decoration cloth, especially in some flammable and explosive occasions in chemical industry, coal, petroleum, military i...
