Abstract

The invention relates to a spinning device for melt-spun spandex. The device comprises a screw extruder, a cross-linking reaction system, a metering pump system, a spinning box, spandex spinning components, lateral blowing systems, a channel, an oil applying system and a spandex winding head, wherein the spandex spinning components are arranged into two rows in a stagger mode in the spinning box and located under a meting pump, and the air outlet sides of every two adjacent lateral blowing systems are arranged in opposite directions. The invention further relates to a spinning method for melt-spun spandex. According to the spinning device and method for melt-spun spandex, on the premise that total output is unchanged, equipment cost and energy consumption are reduced, and component replacement is facilitated.

Description

technical field [0001] The invention relates to the field of spandex spinning production, in particular to a melt-spun spandex spinning production equipment and a production method. Background technique [0002] The production process of melt-spun spandex has the characteristics of short process, small equipment investment, fast recovery, no pollution, economical and environmental protection, etc. Compared with dry and wet spandex spinning, it has significant advantages. Take an 8-position spandex spinning production line as an example, as attached Figure 4 As shown, in the prior art, it includes a spandex special-purpose screw extruder system and a cross-linking reaction device, a set of melt pipeline delivery system, 8 spinning boxes arranged in parallel, each box body adopts 12 heads, Each one has a special spinning metering pump for spandex and its transmission device, 8 sets of side blowing devices arranged in parallel, 8 sets of tanker oiling devices, 16 godets, and 8...
