Description

複合纖維製程Composite fiber process

本發明係與複合纖維有關，特別是有關於一種複合纖維製程。The present invention is related to composite fibers, in particular to a composite fiber manufacturing process.

習知之單絲纖維包括單組份單絲纖維及雙組份單絲纖維。單組分單絲纖維係以單一材料直接由一螺桿押出機搭配模頭熔融擠出後，再進行延伸即可製得；雙組份單絲纖維則可藉由兩台押出機分別熔融並押出兩種相異之材料，再相互結合而成。Conventional monofilament fibers include monocomponent monofilament fibers and bicomponent monofilament fibers. Mono-component monofilament fibers are produced by directly extruding a single material from a screw extruder with a die head, and then extending them; bi-component monofilament fibers can be melted and extruded by two extruders respectively. Two dissimilar materials are combined with each other.

然，單組份單絲纖維因不具強度較高之內紗，而有延伸性差、強度不足之問題，因此於編織時若張力過大則容易斷裂，不便於操作；雙組份單絲纖維則因其內芯及外層之材料性質不同，因此於製造過程中，二者易因加熱而產生不同程度之收縮，進而導致定型後產生例如內芯與外層之介面分層、尺寸安定性不佳、跑紗、紗線霧化等問題，存在亟待改善之缺弊。However, single-component monofilament fiber has the problems of poor elongation and insufficient strength because it does not have a high-strength inner yarn, so it is easy to break if the tension is too large during weaving, which is inconvenient to operate; The material properties of the inner core and the outer layer are different, so during the manufacturing process, the two are prone to shrinkage to different degrees due to heating, which leads to the delamination of the interface between the inner core and the outer layer, poor dimensional stability, and running after shaping. Yarn, yarn atomization and other problems, there are shortcomings that need to be improved.

因此，有必要提供一種新穎且具有進步性之複合纖維製程，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive composite fiber manufacturing process to solve the above problems.

本發明之主要目的在於提供一種複合纖維製程，易於操作且可提升良率。The main purpose of the present invention is to provide a composite fiber manufacturing process, which is easy to operate and can improve yield.

Preferably, the extrusion coating device 20 can be set to heat up in multiple stages to heat and melt the coating material 30, for example, heating at 180°C, 190°C, 200°C, and 210°C for a predetermined time in sequence, so that the temperature can be uniformly heated.
