| The most common cellulose fiber products fade questions:
(1) When the bleeding dye washing, Lase
(2) the use of friction due to contamination when
Discoloration (3) caused by sweat or sunlight
(4) The discoloration caused by repeated washing
For these reasons is that the chemical structure of dyes and chemicals by cracking a combination of fibers dyed or both of the dye compound that caused. About dye bleeding, since the consumer stage repeatedly for safekeeping, wearing, washing, drying fade residual household water caused by the chlorine.
Dyes, fiber bonding is due to the atmosphere of the acid gases contained in the oxidizer family lotion, or other factors cause heat cracking occurred. The dyed hair color because the color change back dye precursor structure by sweat, sunlight, active chlorine, acid gas caused by the decomposition caused.
There is also because resin finishing, softener, etc. caused by induced. On the reaction dyes, direct dyes dyeing, in concentrated color design, humid fastness, wet rub fastness, perspiration sunlight fastness, and so have the problems. In pastel design, the need to pay attention to chlorine-resistant fastness and light fastness.
If it is sulfur, the resistance is also a problem of the presence of a weak chlorine fastness. When dyeing process, concentrated pastel color - multicolor design will have on the white appear, it is necessary to make it beyond the various fastnesses required.
In rayon dyeing, reactions mainly used the dye fixing agent batch processing systems adopt the dipping method and continuous padding to carry out. Continuous padding mode includes, resin processing agent and a fixing agent simultaneously padding, drying, curing, one-bath; in the final tank cleaning project was fixing agent of the pad, nip, through After drying, the resin Padding process agent, the drying, curing of the two-bath method.
嫎 final bath after the batch washing → dehydration → drying
娋 final slot of the continuous process after continuous washing → dehydration → drying → finish padding → drying → heat treatment | | | Views:1323 |  |
