Problems solved by technology

[0006] Traditionally, there is a technology of cutting the iridescent film through a slitting machine to prepare decorative lace. The technology is only to cut the film into narrow strips of corresponding width, and has not carried out corresponding in-depth research and modification. The narrow strips currently prepared have many Fiber properties unsuitable for textile garment comfort

Abstract

The invention discloses a method for preparing a butterfly-scale-structure material through micro-nano laminated film slitting. The method comprises the following steps that 1, micro-nano laminated films are subjected to layered lamination and extrusion film forming to be machined into composite thin films with the thickness ranging from 30 micrometers to 100 micrometers; 2, the simple-layer films obtained in the first step are slit into continuous butterfly-scale-structure material flat filaments through a thin film slitter; 3, each continuous butterfly-scale-structure material flat filament serves as a group and is heated through a heating device; 4, the continuous butterfly-scale-structure material flat filaments obtained in the third step are output to a winding forming device, and continuous butterfly-scale-structure material flat filament bobbins are prepared. According to the method for preparing the butterfly-scale-structure material through micro-nano laminated film slitting, by means of the characteristic that a color effect generated by special micro-nano structures on butterfly wings is a typical structural color, an important research direction is opened in bionics.

Description

technical field [0001] The invention belongs to the technical field of preparation of fiber and yarn materials, in particular to a method for preparing butterfly scale structural materials by cutting micro-nano laminated films, which belongs to the dry spinning method. Background technique [0002] Butterflies show a dazzling blue light under sunlight. This color effect is caused by the special micro-nano structure on the butterfly's wings. It is a typical structural color, and the research on its structural optical mechanism is a bionics an important direction in the [0003] In China, Ren Luquan, Han Zhiwu and others have carried out a series of theoretical and experimental studies on the mechanism of discoloration of the structural color of butterfly wings. Foreign Banerjee, Morpho, Vukusic et al. mentioned that the optical characteristics of butterfly wing scales depend on the wide angle of incidence, polarization direction and wavelength, and are also closely related t...
