Flame-retardant yarn/fabric/clothing
a flame-retardant yarn and flame-retardant technology, applied in the field of flame-retardant yarn/fabric/clothing, can solve the problems of insufficient char length of a fabric, inability to fully understand and master the properties of a fabric to carry out proper blending processing, and inability to be put into mass production, so as to prevent further combustion of the modacrylic, promote the charring of the modacrylic, and reduce the effect of heat resistan

AI Technical Summary
Benefits of technology
This patented technology describes different ways for making fabrics containing special materials without affecting their performance. These techniques include mixing certain type of fiber together to create an intermingled mix instead of just adding them separately. By doing this we aim to achieve better flame resistence while also improving its durability by enhancing it's ability to protect against static electricity charges. Additionally, there exist specific methods used during manufacturing processes to enhance the quality control over the final product. Overall, this new method provides technical benefits compared to existing technologies.
Problems solved by technology
This patented technology relates to making materials from polymeric material called melanin fiber bundles made up mostly of two main components: one component being an organosulfur compound called melanoid rubbing agent; another part containing amine groups attached through carbon atoms between carboxylate rings). These parts can mix together easily when mixed properly. However, there exist differences in these characteristics such as molecular weight, solubility, reactivity towards other substances like acids, bases, etc., causing difficulties in achieving consistently effective mixing processes over time.

Abstract
The present invention provides a flame-retardant yarn/fabric/clothing, containing the following three types of fibers in percentage by weight percent based on their total weight: modacrylic: 20% to 80%; cellulose: 10% to 50%; and polyimide: 1% to 50%. A vertical burning test is carried out in accordance with GB/T 5455-2014 to test the flame retardance of the flame-retardant yarn, fabric or clothing in the present invention, and the measured char length is lower than 150 mm, 100 or 50 mm. The char length is reduced to different extents, and thus different flame retardance requirements are met.
