\n The hazards of textile pH exceeding the standard<\/p<\/p>\n
\n The pH value of normal human skin is between 5.5-6.5, and the chemical reaction is weakly acidic. The sweat and oil secreted by the sweat glands of the skin and sebum itself have a pH value. If the pH value of the outside world is too different from the pH value that the human body normally needs, it will cause people to suffer from diarrhea. Feeling unwell and experiencing many skin diseases \ufffd<\/p<\/p>\n

The pH value of textiles should be in the range of 4.0 to 9.0, when the human body is comfortable to wear \ufffd<\/p<\/p>\n
\n Reasons for unqualified pH value of textiles<\/p<\/p>\n
\n There are many reasons why the pH value of textiles exceeds the standard. If the various dyes and finishing auxiliaries used in the printing, dyeing and finishing processes of textiles are not fully washed or neutralized, and various finishing agents are added during the washing process without standardized control, It will cause the pH value of the final product to exceed the standard. \ufffd\u603b\u7ed3\u4e0b\u6765\uff0c\u6709\u5982\u4e0b\u51e0\u79cd\u539f\u56e0\uff1a<\/p<\/p>\n
