Antibacterial flame-retardant fibers and preparation method of fabric of antibacterial flame-retardant fibers

Abstract

The invention discloses a preparation method of antibacterial flame-retardant fibers. The preparation method specifically comprises the steps that a collected raw white pure cotton waste fabric is crushed after washed and dried, then oxygen bleaching is carried out by using oxygen peroxide, drying is carried out, and then a sodium hydroxide or sodium carbonate solution is used to carry out processing and drying to obtain alkali cellulose; and the alkali cellulose / a hydroxy-containing phosphorus flame retardant and a cross-linking agent are mixed to enable the obtained mixture to subjected toan oxyamination crosslinking reaction to prepare flame-retardant cellulose, the flame-retardant cellulose is mixed with a nano antibacterial sol to prepare a cellulose solution, then spinning is carried out to obtain primary fibers, and the primary fibers are processed to obtain the antibacterial flame-retardant fibers. The invention further discloses a method for preparing an antibacterial flame-retardant fabric. According to the preparation method of the antibacterial flame-retardant fibers, the waste raw white pure cotton fabric is used to prepare the antibacterial flame-retardant fibers, resources are fully used, environmental pollution is reduced, the antibacterial flame-retardant fabric prepared by using the fibers is long-lasting and stable in antibacterial and flame retardant properties and washable, and after 50 times of washing, the antibacterial flame-retardant performance still meets the standard requirements.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of functional textiles, and relates to a preparation method of an antibacterial and flame-retardant fiber. The invention also discloses a method for preparing an antibacterial and flame-retardant fabric by using the self-made fiber. Background technique [0002] In recent years, with the development of society and economy, the country's emphasis on safety, the introduction of military-civilian integration development strategy, the rapid development of textile technology, and the continuous improvement of corporate safety awareness, especially due to the damage caused by textile ignition or combustion to personal property Incalculable losses, many foreign countries have passed strict laws and regulations, requiring special industries such as fire protection, electric power, petrochemical, and metallurgy to use flame-retardant fabrics. During the use of flame-retardant fabrics, as the hu...

Problems solved by technology

Polyester-based fibers will produce molten droplets when used, causing secondary damage to the human body. At the same time, polyester fibers have low moisture regain and poor fabric comfort; Chinese patent "Preparation method of antibacterial and flame-retardant protein viscose fiber", publication : CN102304783A, in the process of preparing antibacterial flame-retardant fiber, just flame retardant slurry, protein glue and chitosan solution are mixed evenly with viscose spinning solution, what adopt is the mixing of physical method, easily cause flame retardant Inhomogeneous mixing with antibacterial agents, resulting in unstable antibacterial and flame retardant functions of fibers, and defects such as not being resistant to washing; the flame retardant fabric developed by antibacterial and flame retardant acrylic fibers has a "smoldering" phenomenon, resulting in a decrease in the flame retardant performance of the fabric
