Flame-retardant pigment particles, flame-retardant colored cotton fabric and preparation method thereof
By constructing core-shell structured flame-retardant particles and bonding them with reactive dyes, the problem of separating flame retardancy from the coloring process was solved, achieving efficient finishing of flame-retardant pigment particles and improving the overall performance and production efficiency of textiles.

AI Technical Summary
In existing technologies, the flame retardant and coloring processes are separated, resulting in repeated washing and drying processes, high energy consumption, and limited overall performance and process economy of textiles. Existing flame retardant materials have failed to achieve sufficient color expression and textile applicability.
Flame-retardant particles with ammonium polyphosphate as the core and silica as the shell were constructed, and flame-retardant pigment particles were prepared by using silane coupling agents to bond with reactive dyes. These particles were then applied to the surface of cotton fabrics using a spraying method, combined with a multi-spraying-short-time pre-drying treatment.
It achieves integrated flame retardancy and coloring, reduces the amount of flame retardant pigment particles used, avoids raw material waste, improves dispersion stability and thermal stability, ensures that functionality does not affect the fabric's feel and breathability, and has high process flexibility, making it easy to carry out continuous production.
