Method for splitting collar or sleeve

Abstract

Disclosed is a method for splitting a collar or a sleeve. Using nylon as a connecting thread guarantees the strength requirement of the connecting thread in a production process of a to-be-split semi-finished product and can dissolve the nylon via a splitting agent to split the collar or the sleeve. In the splitting agent, formic acid can dissolve the nylon and has no adverse effect to the collar and the sleeve; and a fog inhibitor can inhibit volatilization of the formic acid, so that the formic acid is acted on the nylon more effectively thus improving the utilization rate of the formic acid. The splitting agent is employed to directly act on a connecting thread of the collar or the sleeve, thus operation is convenient; and the connecting thread can be dissolved provided that the splitting agent contacts it for 1-2 s, thus splitting efficiency is high.
