Problems solved by technology

In addition to strict requirements on conventional flame retardant test indicators such as limiting oxygen index (LOI) and damage length, after-flame time, long smoldering time, etc., special emphasis is also placed on the toxicity level of smoke production and smoke density values. Many halogen-containing flame-retardant textiles The requirements cannot be met at all, which urgently requires the development of new environmentally friendly flame-retardant textiles
[0005] The national standard "Classification of Combustion Behavior of Building Materials and Products (GB8624-2012)" revised in 2012 has greatly changed the test methods and basis used for judging the combustion performance of materials, especially considering the calorific value of combustion, fire development rate, smoke Combustion characteristic elements such as gas generation rate; increase combustion calorific value, fire development rate, smoke generation rate and other indicators, and require textiles to reach B1 level: limiting oxygen index ≥ 32%; damage length ≤ 150m; continued combustion time ≤ 5 seconds; Smoldering time ≤ 15 seconds; burning drips do not cause absorbent cotton to burn or smolder, this requirement makes the development of flame-retardant textiles face severe challenges
[0018] None of the above patents involves flame retardant properties. Since antibacterial and antifungal agents are different fields from flame retardant, most antibacterial agents and antifungal agents affect the flame retardant effect. Adding antibacterial and antifungal agents to flame retardant textiles makes flame retardant textiles flame retardant The performance is greatly reduced, and it cannot meet the requirements of GB8624-2012 or GB20286 for flame retardant grade 1 or B1

Abstract

The invention discloses a durable anti-flaming anti-microbial mould-proof fabric. The durable anti-flaming anti-microbial mould-proof fabric contains an anti-flaming dacron fabric and an anti-microbial agent, a mould-proof agent, an anti-flaming synergist, a photocatalyst and a penetrating agent which are combined with the anti-flaming dacron fabric in a physical manner and chemical manner, wherein the physical manner is to combine through the cementing action of the anti-flaming macromolecule adhesive and the chemical manner is to bond through the crosslinking by generating NCO by de-blocking the phosphorus containing blocking type polyurethane prepolymer at high temperature. The durable anti-flaming anti-microbial mould-proof fabric provided by the invention still has excellent anti-microbial mould-proof performances after being washed for 40 times with water, and formaldehyde can be removed. The anti-flaming performance after the fabric is washed for 50 times with water still can meet the GB8624-2012 B1 level and GB20286-2006 anti-flaming level 1 requirements.

Description

technical field [0001] The invention relates to a flame-retardant, antibacterial, mildew-proof fabric and its preparation method and application, in particular to a durable flame-retardant, antibacterial, mildew-proof fabric, its preparation method and application. Background technique [0002] Textiles can absorb various nutrients in the air. Under suitable temperature and humidity conditions, microorganisms residing on textiles can reproduce and spread in large numbers, decompose and produce secretions, bring ammonia and other odorous substances, or form bacteria on fabrics. Spots will cause discomfort or adverse effects on the human body, and textiles will become mildewed, embrittled or even aged. With the development of social economy and the improvement of living standards, new market demands are generated. Consumers hope that textiles have the function of antibacterial and mildew resistance, so as to meet the needs of civilized, clean and comfortable environmental life...
