TECHNICAL FIELD

[0001] The application relates to the field of yarn processing, in particular to a nylon safety environment-friendly elastic processing technology and a processing device. BACKGROUND

[0002] The elastic processing technology of civil nylon filaments is to stretch, heat and twist the POY raw yarn produced by pre-spinning, so that the raw yarn is deformed by stretching, heat setting and the like, so that the fiber is curled and the DTY nylon filaments with loftiness and elasticity are formed.

[0003] The existing deformation heat box of the elastic machine with a heat preservation device can not be used to heat and stretch the nylon filaments, because the biphene steam needs to be used to plasticize the nylon filaments in a certain temperature environment, and the biphene steam is a toxic chemical gas. Therefore, the existing elastic machine needs to maintain air circulation when in use, so as to avoid the biphene poisoning of the workers. However, the biphene steam is easily discharged, which can affect the environment. SUMMARY
