摘要:
A composite polymer fiber is produced employing at least two polymer compounds according to a process for producing a composite polymer fiber including the steps of supplying at least two polymer compounds; forming a belt flow by arranging alternately unmixed strips of the polymer compounds supplied; and injecting the belt flow after it is compressed such that the thickness of the belt flow may be longer than the width thereof and that multiple layers of the polymer compounds may be parallel to the longer axis of the fiber. According to this process, there is obtained a fiber having a multilayered structure, in which the thickness of each layer can be controlled with optical accuracy since the multilayered structure is formed in one step, and also having a rectangular cross section in which each layer in the fabric is oriented parallel to the longer axis of the fiber, so that the layers can be easily oriented, when woven into a fabric, in such a direction as to obtain high-intensity coherent beams of light.

A color-developing composite short fiber having a length of 0.01 to 100 mm is obtained by cutting a color-developing short fiber capable of reflecting visible rays and interfering with visible rays consisting of two or more kinds or polymer compounds having different refractive indices which are laminated alternately. A color-developing structure is formed by binding particles of the short fiber to one another, dispersing the short fiber in a mixture with other materials or adhering the short fiber on the surface of a support. Further, a color-developing composite short fiber having a length of 0.01 to 100 mm is obtained by cutting a color-developing composite fiber comprising two or more polymer compounds having different refractive indices which are laminated alternately forming a layer capable of reflecting visible rays and interfering therewith and a layer capable of reflecting invisible rays and interfering therewith.
