Implementation result
Table 1 comparative example and embodiment test result
Applicant is through a large amount of experiments, be surprised to find that, after adding pyridines activator, there is beyond thought bleaching effect, pyridines activator not only can effectively be bleached by activated hydrogen peroxide, add whiteness, may because pyridines activator can react with trace heavy metal element, Hydrogen Peroxide catalyst, it can effectively decompose by catalysis peracid salt, completes and scourings and bleaching to the low temperature of family's textile fabric.
The result of capillary effect from table 1, add low temperature and scouring and bleaching after agent, the capillary effect of family's textile fabric also has a certain upgrade, because Tea Saponin has stronger washing, dispersion, impurity removal function, can remove the impurity on family's textile fabric preferably.
Further find out from table 1, use low temperature is scouringed and bleaching after agent, the bursting strength of fabric is higher than the brute force of conventional high temperature process, this is because the easy disproportionation of hydrogenperoxide steam generator generates the free radical without selecting row under high temperature, comparatively large to the infringement of family's textile fabric, so low temperature of the present invention agent of scouringing and bleaching reaches outside good whiteness at low temperatures, a textile fabric infringement can also be made less, there is good practical value.
Although last it is noted that described the present invention and advantage thereof in detail above, be to be understood that and can carry out various change when not exceeding the spirit and scope of the present invention limited by appended claim, substituting and converting.And scope of the present invention is not limited only to the specific embodiment of process, equipment, means, method and step described by description.One of ordinary skilled in the art will readily appreciate that from disclosure of the present invention, can use perform the function substantially identical with corresponding embodiment described herein or obtain and its substantially identical result, existing and that will be developed in the future process, equipment, means, method or step according to the present invention.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
