- 1 shows an example of the —NMR measurement result of acryl resin.
- Figure 2 shows an example of the —NMR measurement results of acryl resin alone coated on a conventional coated cloth.
- the present invention has been completed by investigating that the organic peroxide mixed in the resin layer chemically reacts with the disperse dye and exerts a decolorizing effect, and has been completed. It also has.
- the conventional technique has been to prevent the migration of the dye by a resin film or fine particles having a low affinity and compatibility with the disperse dye.
- the disperse dye migrating from the fiber base fabric in the coating process is chemically reacted with the organic peroxide mixed in the resin layer to be colorless, thereby producing a disperse dye. It is intended to prevent dye transfer contamination and has been completed by a completely new technical concept different from the conventional method.
- a method for making the dye colorless a method using hydrosulfite for reduction washing after dyeing is known.
- this reducing agent hydrosulfite
- this reducing agent is contained in a coating resin to prevent dye transfer contamination.

- disilver oxide having an aromatic ring When disilver oxide having an aromatic ring is used as an organic peroxide, radicals generated by the decomposition of disilver oxide in the coating process migrate from the dyed polyester fiber into the coating resin. Attacks the resulting disperse dye and decolorizes it. In addition to the decoloring effect, the disassembled geosilver oxide also attacks the coating resin, and the disassembled disilver oxide itself binds to the coating resin to coat the aromatic ring. It is thought that it will be added to the resin.
- the aromatic ring is present in the coating resin after the coating process.

Similar ones are preferably used. Specifically, it depends on the selected drying temperature and drying time, but it is preferable that at least half of the organic peroxide decomposes during the drying time. More specifically, the decomposition temperature of the organic peroxide by heating is preferably, for example, 60 ° C or higher, and more preferably, the decomposition temperature of 80 ° C or higher is effectively used. The upper limit of the decomposition temperature is not particularly limited, but is generally about 150 ° C.
