Abstract
The present invention relates to a fiber production system (1) and production method which enables heat treatment applied during fiber production to be performed as applying laser on the fiber. The objective of the present invention is to provide a fiber production system (1) and production method which enables to perform momentary heat treatment on the filament (F) via laser beam (L) and which eliminates defected points in the filament structure by heating fast and drawing in fiber production.
Claims14
A fiber production system, for preventing the skin-core structure formed in the fiber and/or eliminating this structure, comprising:
- at least one molten forming member configured to heat and melt a polymeric crude material to be used in fiber production,
- at least one extrusion member configured to pass the molten polymeric crude material through at least one spinneret at its an end part of the at least one extrusion member,
- at least one cooling unit providing a filament structure to the polymeric crude material going out of the at least one extrusion member by cooling the polymeric crude material, a plurality of rollers configured to heat the polymeric crude material at a temperature above a glass transition temperature or a crystallization temperature, and the fiber material in filament form to reach a predetermined crystallinity by being drawn at a predetermined tension,
- at least one mobile laser device configured to apply laser beam on the filament during drawing the filaments with the rollers to form a balanced heat distribution for eliminating defects in the filament structure,
- at least one heated chamber located between two adjacent rollers for applying heat on the fiber material in order to increase crystallinity in the fiber material drawn with the rollers, and enabling the continuity of the filament structure provided to the fiber material,
- at least one control member to guide the mobile laser device to an area according to data received from at least one camera, wherein the at least one camera detects defected points in the filament structure during the filament material being drawn by the plurality of rollers, and to correct the areas with defected points with heat and drawing by applying the laser beam locally on the filament structure,
- at least one winding machine for packing the filament material in a form of bobbin for packaging,
- wherein all rollers are arranged linearly between the at least one cooling unit and the at least one winding machine.
