Multifilament Yarns

Polylactide (PLA) was mixed with 4 wt.% of carbon nanotubes (CNTs) to produce electrical conductive multifilament yarns by melt spinning process for humidity detection. Thanks to a variation of electrical conductivity, this flexible sensor could detect the moisture presence. The introduction of plasticizer was necessary to ensure higher fluidity and drawability of the blend during the spinning process. The plasticizer modifies the crystallinity and the mechanical properties of the yarns. The effectiveness of this sensor (PLA/4 wt.% CNTs fibres) sensitive to humidity, is optimal when the spinning conditions are adapted. In this way, the temperature and the rate of the drawing roll were reduced. The influence of these parameters on the crystallinity, the mechanical properties and the sensitivity of the yarns were studied. Once the appropriate spinning conditions found, one humidity sensitive yarn was processed and the repeatability and efficient reversibility of its sensitivity were highlighted.

Spinning Process

Colored luminous fibers were prepared by a melt spinning process, adding colored pigments and long afterglow rare earth material into polyamide fiber. The colored luminous fibers had a variety of colors in photopic vision, and emitted colored light in mesopic vision and scotopic vision. Based on the experimental data of the emission spectra and the test luminance of the luminous fibers, the effect of the emissive colors of the luminous fibers on the equivalent luminance at different vision states was analyzed. The results showed that the effect of the emissive colors of white, red, yellow, and green luminous fibers on the equivalent luminance was not obvious in photopic and scotopic vision, but that of blue luminous fiber was obvious in photopic vision but not in scotopic vision.
