“…Several research in hairiness have been performed for analyzing the quality of the fiber. [15][16][17][18][19][20] The hairiness analysis is usually applied in the production process of the fibers. In most of the researches, hairiness analysis is done for a separated fiber observed by microscope.…”

“…Actually, automatic systems for hairiness analysis are using for analyzing the quality of the fiber in textiles during the production process. 20 In those systems, the hairiness is quantified by measuring the number of hairs, the length of the hairs and the density of the yarn. 15,19 For the carpet wear assessment, according to the standards, the carpet must be analyzed in the entire carpet and the carpet can not be touched by the expert.…”

Recently, an automatic system for grading appearance retention in carpets using our own scanner and image analysis techniques was proposed. A system for carpets with low pile construction and without color patterns has been developed. Appearance changes in carpets with high pile construction were still not well detected. We present an approach based on surface metrology that extract information given by the hairs on the carpet surface. These features are complementary to the texture features previously explored. By combining both features, we expand the use of the automatic grading system including some carpets types with high pile construction.

This paper presents a study performed with a custom developed yarn parameterization system based on capacitive and optical sensors. It describes the statistical and signal processing correlation between the most common yarn parameters (diameter, mass and hairiness) determined with different technological approaches, and generally used to infer information about yarn quality. The designed sensors system is fully described. All data acquisition and processing is performed using a DAQ board form National Instruments (USB-6251) and custom software developed in LabVIEW     . The results obtained with a 100% cotton yarn with a linear mass of 295 g/km are presented, showing that there is a significant correlation between the different measured yarn parameters.I.
