Study on Optical Properties of Silk-like Fabrics

Abstract

Tests were carried out with a gonio-photometer to investigate optical properties of silk-like synthetic fiber fabrics. To compare silk-like fabrics with natural silk fabrics, habutai and crepe de chine of silklike synthetic fibers as well as those of natural silk fibers were used as samples. The following results were obtained :1. The difference in optical properties of silk-like and natural silk fabrics can be distinguished by comparing their reflected light distribution curves and quantity of reflection obtained by revolving specimens.2. Little differences have essentialy been found between silk-like and natural silk fabrics. However a detailed observation has revealed that a silk-like fabric has little amount of diffused reflected light and the specular reflected light of a silk-like fabric tends to gather. This causes the visual sensory differences in luster.3. Sensory tests were carried out of a difference in luster of a silk-like and a natural silk fabric. The crepe de chine of a silk-like synthetic fibers can be distinguished from that of natural silk fibers by the difference of degree of creping. By contrast, a habutai of silk-like synthetic fibers can not completely be distinguish from that of natural silk fibers. In other words, a habutai of polyester fibers is much similar in visual luster to that of natural silk fibers.

Optical fibers for smart photonic textiles

“…Prediction of textile appearance due to multi-fi ber redirection of light was addressed by Rubin et al (1997), Grasso et al (1997) and Schuster et al (2003). It was also established that the shape of the individual fi bers comprising a yarn bundle has a major effect on the appearance of the resultant textile (Maekawa et al , 1984;Rubin et al , 1994;Sirikasemlert and Tao, 1999;Yamaguchi and Takanabe, 2001;Zhang et al , 2003), including textile brightness, glitter, color, etc. The use of synthetic fi bers with non-circular cross-sections, or microstructured fi bers containing air voids metallic color of the chalcogenide glass.…”

Deep‐black‐coloring effect of fabrics made of noncircular cross‐section polyester filaments

“…In apparels business, appearance and color were the main factors that affect the sales and quantities of clothing in the fashion industry, along with its style, materials texture and handle. This could mainly be affected by light performance resulted from the features of fibers used, the important one of which was the fiber's cross‐section . Contours or shapes of noncircular cross‐section (NCCS) fibers were the most basic feature and of important issue used to identify useful information, and NCCS fibers were also called profiled or shaped fiber differential to the conventional round ones in textiles industrials…”

Visible Light Shielding Performance of Fabrics with Non-Circular Cross Section Fiber

“…A new method was developed to calculate the refractive index [9]. The Japanese [10][11][12][13][14][15] have carried out studies on the properties of NCCS fibers, to some extent, concentrating on performances of the fiber assemblies, for instance the handle, moisture permeability, or imitating the style of the natural silk fiber fabric. Recently, various types of NCCS fibers were used to produce fiber reinforced composites (FRCs) [16][17][18][19].…”
