Problems solved by technology

[0003] However, if the test method for vertical ignition of fabrics in GB / T 5455 is adopted, the afterburning energy can be controlled within 2 seconds by controlling the fiber ratio and gram weight, but it is difficult to control the smoldering within 5 seconds or 2 seconds
Because modacrylic is gas-phase flame-retardant, it blocks the contact between oxygen and non-flame-retardant fibers, and slows down the burning of non-flame-retardant fibers. After removing the fire source, some non-flame-retardant fibers may smolder for more than 2 seconds or appear carbonized due to heat preservation. The effect continues to maintain a red and bright state, which is included in the smoldering time because it is easily confused with the smoldering state, which is not good for judging the flame retardancy of fabrics
In order to control the smoldering within 2 seconds, the conventional method is to add 20% to 30% of expensive phosphorus-based flame-retardant viscose or post-treat the fabric for flame-retardant processing, and the cost of the fabric is relatively high

Abstract

The invention discloses a modacrylic, lyocell and nylon blended flame-retardant fabric. Yarn in the flame-retardant fabric contains, by mass, 40-70% of modacrylic, 20-52% of lyocell and 5-15% of nylon. Due to effective cooperation of modacrylic, lyocell and nylon, it can be guaranteed that after-flame time of the fabric under GB / T 5455 test conditions can be controlled not longer than 2 seconds, and afterglow time is controlled not longer than 2 or 5 seconds.

Description

technical field [0001] The invention relates to the fields of chemical industry, electric power, textile and labor protection, in particular to a fabric suitable for providing flame retardancy. Background technique [0002] Modacrylic and non-flame-retardant cotton fibers can be mixed in a certain ratio to make the whole mixture have permanent flame retardancy. When the fabric is ignited on the side according to the ISO15025 standard, the continuous burning and smoldering of the fabric can be controlled to less than 2 seconds. , meeting the specified requirements. [0003] However, if the vertical ignition test method of GB / T 5455 fabric is used, the afterburning energy can be controlled within 2 seconds through the control of fiber ratio and gram weight, but it is difficult to control the smoldering within 5 seconds or 2 seconds. Because modacrylic is gas-phase flame-retardant, it blocks the contact between oxygen and non-flame-retardant fibers, and slows down the burning ...
