A kind of antibacterial flame retardant fiber and preparation method thereof

Abstract

The invention discloses a preparation method of an antibacterial and flame-retardant fiber, which specifically comprises: washing and drying the collected white pure cotton waste fabrics, crushing them, then using hydrogen peroxide for oxygen bleaching, drying, and then using sodium hydroxide or sodium carbonate solution Processing and drying to obtain alkali cellulose; mixing alkali cellulose / hydroxyl-containing phosphorus flame retardant and cross-linking agent to make the mixture undergo a hydroxylation cross-linking reaction to prepare flame-retardant cellulose, and combine flame-retardant cellulose with The nano antibacterial sol is mixed to prepare a cellulose solution, and then spun to obtain primary fibers, and the primary fibers are treated to obtain antibacterial and flame-retardant fibers. The invention also discloses a method for preparing the antibacterial and flame-retardant fabric. The invention discloses a method for preparing antibacterial and flame-retardant fibers. The antibacterial and flame-retardant fibers are prepared by using waste and old white pure cotton fabrics, which can make full use of resources and reduce environmental pollution. The antibacterial and flame-retardant fabrics prepared by using the fibers have long-lasting antibacterial and flame-retardant properties. Stable and washable, after 50 times, the antibacterial and flame retardant properties still meet 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 antibacterial and flame retardant fibers. The invention also discloses a method for preparing antibacterial and flame retardant fabrics by using the self-made fibers. Background technique [0002] In recent years, with the development of society and economy, the country's emphasis on security, the introduction of the military-civilian integration development strategy, the rapid development of textile technology, and the continuous improvement of enterprise safety awareness, especially due to textile ignition or combustion-supporting effects on personal and property Immeasurable losses, many foreign countries have passed strict laws and regulations, requiring special industries such as fire protection, electric power, petrochemical, metallurgy, etc., to use flame retardant fabrics. During the use of flame retardant fabrics, ...

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
