DYEING OF TEXTILE MATERIALS |
摘要 |
<p>A method of dyeing cellulosic fibers or fabrics using pre-metallized acid dye by pretreating the fabric with a cationic agent having a plurality of cationic centers and optionally after treating the dyed material with a cationic polymer is disclosed. The cationic polymer is desirably a polyquaternary amine material especially a poly(DADMAC) or polyvinylpyridine. Material dyed by the method has a "washed out" appearance similar to fabrics dyed using the "Jarofast" process, but the availability of a wide range of pre-metallized dyes gives a wider color range, and the method enables a wider range of substrates to be dyed successfully, including lyocell fiber materials e.g. those sold under Courtauld's trademark "Tencel" and blend/union materials with polyamides, easier processing and superior wash and light fastness.</p> |
