Problems solved by technology

Although the patent application scheme has the advantages of flame retardancy, arc resistance and wear resistance, but due to the addition of halogen-containing flame retardants during spinning, toxic and harmful gases will be released during combustion, which is detrimental to environmental protection and safety.
In addition, the use of nylon will cause the fabric to melt and drip when exposed to fire, which may cause secondary damage to the wearer.
[0007] Also as document D).CN102634908B discloses "oil-repellent, water-repellent, flame-retardant, anti-static, silicon-removing multi-functional fabric", the technical effects recorded in paragraphs 0012 to 0015 of the patent specification are essentially achieved through the combination of 100D / 48F The post-finishing of the base fabric woven by DTY heavy mesh polyester low-elastic flame-retardant yarn as the fiber, such as silicon-removing finishing, oil-repellent and water-repellent finishing and baking, does not have a permanent flame-retardant effect.

Abstract

The invention discloses permanent flame-retardant multifunctional fabric and a making method thereof and belongs to the technical field of protecting fabric and processing thereof. The permanent flame-retardant multifunctional fabric is formed by interweaving warp yarn and weft yarn. The permanent flame-retardant multifunctional fabric is characterized in that a raw material by which each of the warp yarn and the weft yarn is made is a mixture of high-temperature-resistant natural flame-retardant fibers and natural fibers or regenerated cellulose fibers, the high-temperature-resistant natural flame-retardant fibers account for 40-90% of the fabric, the natural fibers or the regenerated cellulose fibers account for 8-58% of the fabric, and antistatic filaments are woven in the warp yarn at intervals and account for 1-3% of the fabric. The permanent flame-retardant multifunctional fabric can permanently maintain ideal flame-retardant characteristics which do not decline with passage of time or increase of washing times, demonstrates high environment friendliness, breathability and wearing comfortability and has safety, and excellent antistatic performance can be guaranteed lastingly; processes are simplified, so that the above advantages of the fabric can be demonstrated comprehensively.

Description

technical field [0001] The invention belongs to the technical field of protective fabric and its processing, and in particular relates to a permanent flame-retardant multifunctional fabric, and also relates to a preparation method of the permanent flame-retardant multifunctional fabric. Background technique [0002] With the continuous improvement of people's health awareness and safety awareness, the requirements for textile fabrics with protective functions are becoming increasingly stringent. In recent years, in industries such as petrochemical, electric power, fire protection, coal mining, oil refining, and pharmaceuticals, clothing made of flame-retardant fabrics is generally favored. [0003] Due to the relatively expensive price of fibers with flame-retardant properties, the flame-retardant effect of flame-retardant fabrics in the prior art is mostly reflected by the finishing of the fabric. Common methods such as padding and drying methods, dipping and drying method...
