Problems solved by technology

Although the above-mentioned methods can produce antibacterial and flame-retardant fibers, there are still some shortcomings: 1. The blending method needs to add antibacterial agents and flame retardants separately, and the dispersion of the two in the fibers is poor; 2. Manufacturing by skin-core composite spinning method The process is difficult and the requirements for equipment are high, so the spinning cost is too high; 3. Long-term use of silver ion antibacterial agents may cause heavy metal accumulation in the human body and endanger human health

Abstract

The invention discloses a flame-retardant antibacterial fabric and preparation method thereof, and belongs to the technical field of textile material production. The preparation method comprises the following steps that a regenerated cellulose fiber solution is mixed with a phosphorus-nitrogen composite flame retardant, and wet spinning is carried out to obtain flame-retardant fibers; the phosphorus-nitrogen composite flame retardant is prepared from the following components in parts by weight: 40-60 parts of triphenyl phosphate, 20-30 parts of ammonium polyphosphate, 26-28 parts of melamine cyanurate and 2-3 parts of zinc borate; the regenerated cellulose fiber solution is mixed with an antibacterial agent, and wet spinning is carried out to obtain antibacterial fibers; the antibacterialagent is prepared from the following components in parts by weight: 18-24 parts of water-soluble chitin, 22-28 parts of citric acid, 8-12 parts of juniperus chinensis oil and 30-40 parts of deionizedwater; the flame-retardant fibers and the antibacterial fibers are drawn according to the weight ratio of 1-2: 1, and roving, spinning and two-for-one twisting are sequentially performed to obtain flame-retardant antibacterial yarns; and the flame-retardant antibacterial yarns are blended with cotton fibers to obtain the flame-retardant antibacterial fabric. The flame-retardant antibacterial fabric is excellent in flame-retardant antibacterial performance, good in washability and high in safety and comfort level.

Description

technical field [0001] The invention belongs to the technical field of textile material production, and in particular relates to a flame-retardant and antibacterial fabric and a preparation method thereof. Background technique [0002] At present, more than 60% of indoor fires in the world are caused by textiles, and more than 80% of fire deaths are caused by inhalation of poisonous fumes or suffocation. With the development of human civilization and the formulation of fire safety regulations in various countries, higher and higher requirements are put forward for flame retardant materials. Flame-retardant fabrics refer to fabrics that can prevent themselves from being ignited or delay and stop burning when they come into contact with flames or hot objects. There are two types: fiber flame-retardant and finishing flame-retardant. Fiber flame retardancy includes the flame retardancy of the fiber itself, such as polym-phenylene isophthalamide fiber, polyamide-imide fiber, etc...
