Problems solved by technology

The existing flame-retardant fabrics for work clothes are mostly cotton fabrics with flame-retardant finishing, which generally can only meet the tests of burning when exposed to an open flame source (such as vertical method, horizontal method, 45°C combustion method, etc.), these test conditions The flame state of the fire is relatively stable, but the actual fire situation is far from the case, and the fabrics that can only pass this kind of test cannot meet the protection requirements of clothing in the real fire environment
Professional fire-resistant clothing is made of multi-layer fabrics, which is heavy to wear and cannot carry out normal production activities. It is not suitable for daily operations in industrial environments.
[0004] The protection of molten metal has always been a thorny problem. Traditional protection methods mostly use thick cotton canvas fabrics with a unit weight of more than 350g / m2. Although flame-retardant finishing can help improve the protection ability of molten metal, there are still Burned through, etc.; aluminum-film composite fabrics have good protective performance, but the fabric has poor air permeability and poor wearing comfort; another kind of thick fabrics made of cowhide or wool as the main material, on the one hand, is also too heavy. , on the other hand, the dimensional stability of washing is poor
Aramid flame-retardant protective clothing mainly has the defect of poor moisture absorption and air permeability, and the price is relatively high, so there are only a few applications. In short, the existing fabrics of this kind have disadvantages that are not easy to overcome
At the same time, the fabric preparation system has played a vital role in improving the surface structural strength of the fabric and the impact resistance of molten metal, but the existing fabric preparation system has limited promotion in these aspects.

Description

technical field [0001] The invention relates to the technical field of fabric preparation, in particular to a flame-retardant and molten metal impact-resistant fabric under sudden conditions, a preparation system and a preparation method thereof. Background technique [0002] Flashover is a special phenomenon similar to deflagration that occurs when a fire develops to a certain stage in a certain limited space. Flashover means that with the continuous increase of the burning intensity of the initial fire, the combustible gas reaches the ignition concentration limit, and the temperature caused by the thermal radiation feedback rises to a dangerous value (generally about 500 ° C), which is the comprehensive development of the initial fire to the fire. At the beginning, it was also a transition from partial to full-room combustion of the indoor fire system. When flashover occurs, the original local, low-intensity, and small-scale combustion quickly spreads to the entire space,...
