Abstract

The invention relates to a pre-wetted modified dust-free cleaning cloth and making method thereof. The making method of the pre-wetted modified dust-free cleaning cloth includes the following steps: modification: organic compound modifier aqueous solution is adopted for carrying out after finishing on dust-free cleaning cloth, water bath ratio is 1:5-50, the concentration of organic compound modifier is 0.1-10%, the organic compound modifier is provided with a hydroxyl and an active group, the active group is hydroxyl, amidogen or sulfo group, reaction temperature is 90-170 DEG C, reaction time is 1-30min; and pre-wetting: pre-wetting agent is adopted to pre-wet the dust-free cleaning cloth after being modified. The invention utilizes organic compound modifier provided with active group to modify the dust-free cleaning cloth in advance, surface energy of the dust-free cleaning cloth can be obviously improved, absorbability on granule and imbitition effect can be improved, and the function of removing organic molecule or inorganic ion dirt can be realized while realizing dust particle and metal dust capturing.

Description

technical field [0001] The invention relates to the field of clean room consumables, more specifically, to a pre-wet modified dust-free wiping cloth and a manufacturing method thereof. The pre-wet modified dust-free wiping cloth can effectively remove organic dirt, inorganic Dirt, dust particles and metal dust and other functions are mainly used for cleaning semiconductor production line wafers, microelectronic chips and semiconductor assembly lines. In addition, the application of this pre-moistened modified dust-free wiping cloth also involves Display panels, printed circuit boards, precision instruments, optical products, medical equipment, laboratories, dust-free workshops and production lines, etc. Background technique [0002] As the manufacturing of semiconductor integrated circuits is progressing, the density of components is getting higher and higher, and the wire diameter of the corresponding semiconductor manufacturing process is also tending to be miniaturized, a...
