In order to further illustrate the technique effect of the present invention, the cold bleaching principle and measure of merit obtained by the present invention are said
It is bright as follows：
Test philosophy：In hydrogen peroxide bleaching system, there is certain stability constant in complex compound, in the bar of certain pH value, temperature
Appropriate copper ion can be discharged under part, copper ion can be catalyzed the decomposition of hydrogen peroxide, and catalytically bleaching effectively improves fabric
Whiteness.
Method of testing：The low-temperature low-alkali bleaching process for adding hydrogen peroxide cold bleaching catalyst of the present invention is respectively adopted：
(50%) 4~6ml/L of hydrogen peroxide, and add 1~2ml/L of refining agent containing cold bleaching catalyst of the present invention, sodium hydroxide 1
~2g/L, at 80 DEG C bleach 50~60min and be not added with bleaching catalyst with the conditions of low-temperature low-alkali bleaching process with
And 1~2ml/L of hydrogen peroxide of the high-alkali bleaching process 50% of conventional high-temperature, enzyme 1g/L, 1~2g/L of sodium hydroxide are refined, at 95 DEG C
60min is bleached, bafta is bleached, whiteness, capillary effect and the fibre damage degree of bafta after bleaching is determined.
Whiteness：Sample is folded 4 layers, is determined 4 times, averaged using the whiteness instrument of WSB- II.
Capillary effect：By FZ/T01071-1999《Textile capillary effect test method is determined》.
Bursting strength：According to GB/T7742.1-2005《Textile fabric bursts performance Part I：Bursting strength and
Burst the measure hydraulic method of expansion ratio》Determine.
Measurement result is as follows：
| Whiteness (%) | Capillary effect (cm/30min) | Bursting strength rate of descent (%) | Bleaching conditions | |
| Pure cotton knitting fabric | 25.68 | 0 | / | / |
| It is not added with the bleaching process of bleaching catalyst | 61.32 | 4.3 | 5.2 | 80℃×60min |
| Traditional bleaching process | 76.82 | 11.5 | 17.1 | 95℃×60min |
| The bleaching process of addition cold bleaching catalyst of the present invention | 75.64 | 10.8 | 6.5 | 80℃×60min |
From the test result in upper table, add after cold bleaching catalyst of the present invention, bafta is carried out under similarity condition
The whiteness and capillary effect of fabric of the hydrogen peroxide low-temperature low-alkali bleaching than being not added with bleaching catalyst are significantly improved；Meanwhile, it is relatively conventional
The technique of the high-alkali bleaching of high temperature, by 95 DEG C can be down to 80 DEG C or so by bleaching temperature, not only reduce energy resource consumption but also not lost system
Whiteness, capillary effect after bleaching, and the bursting strength of fabric also significantly increases, hence it is evident that the damaged condition of cotton fiber is reduced,
It is integrally improved the quality of bafta.
The foregoing is only a preferred embodiment of the present invention, not makees any formal limitation to the present invention；It is all
The those of ordinary skill of the industry can be described in by specification and described above and swimmingly implement the present invention；But, it is all to be familiar with
