“…La separación de 1 kg de fibra gruesa y down puede tomar una semana. Para este procedimiento, el vellón y la fibra cruda son abiertas previo al descerdado manual (Wang et al, 2008), proceso en vellón de vicuña que puede tomar siete turnos de ocho horas para obtener 700 g de fibra fina (Hunter, 2020), en Figura 1. Descerdado manual de la fibra de vicuña Figura 2.…”

“…La longitud de la fibra fue homogénea según el sitio de muestreo del vellón (entre 33.70 y 35.65 mm), en cambio, en vicuñas macho, Carpio y Santana (1982) repor-taron variaciones entre 25.91 y 38.61 mm, con una menor longitud de fibra en la paleta respecto a costillar medio y grupa. Por otro lado, la longitud corta (20 a 25 mm) limita en gran medida el sistema tradicional de peinado (Hunter, 2020), por lo que se recomienda el procesamiento textil de cardado (Carpio y Santana, 1982;Trejo et al, 2009), con el fin de fabricar una prenda exclusiva.…”

Actualmente, se dispone máquinas descerdadoras comerciales de cachemira(Wang et al, 2008;Hunter, 2020) que reduce drásticamente el tiempo de separación de las cerdas de las fibras más finas(McGregor, 2018). El descerdado mecánico en una miniplanta se debería implementar cuando se esquilan grandes can-tidades de fibra de vicuña(Quispe et al, 2015).…”

El objetivo de la investigación fue determinar la variación de las características textiles y longitud de fibra al descerdado manual del vellón de vicuña, así como evaluar la influencia del sexo, edad, sitio de muestreo del vellón, y lugar de procedencia de la vicuña sobre las características de calidad de la fibra. El descerdado manual se realizó en 77 muestras de vicuñas provenientes de tres provincias del departamento de Apurímac, Perú. Las características textiles de la fibra antes y después del descerdado fueron evaluadas usando el equipo OFDA 2000 y mediante el análisis de varianza, prueba de t y Tukey (α=0.05). La calidad de fibras descerdada es superior a la fibra no descerdada, debido a la reducción del diámetro medio de fibra (DMF) (-1.68 μm), desviación estándar de DMF (DE) (-0.73) y finura al hilado (FH) (-1.27 μm) y al incremento del porcentaje de fibras <30 µm (FC) (1.12%) y de la curvatura media (CU) (6.75°/mm). En fibra descerdada los juveniles tienen un DMF más fino (12.24 μm) que las adultas (13.01 μm), el DMF del costillar medio es más fino (12.39 μm) respecto a paleta (12.81 μm) y grupa (12.77 μm). Asimismo, se encontró variación de las características textiles (DE, CV, FC, y CU) y longitud de fibra entre los vellones de las tres provincias de Apurímac. En conclusión, el descerdado manual reduce el diámetro medio de fibra y su desviación estándar, y aumenta la curvatura media y el confort de la fibra, mejorando las propiedades de calidad y uniformidad del hilo.

“…For example, sheep wool, goat hair, alpaca hair, and horse hair are predominantly fibres that are used in the textile industry [ 17 ]. The location of these dairy animals, which are grown in a broad diversity of heights and temperatures, influences the mechanical properties of these fibres [ 18 ].…”

Physical, Mechanical and Perforation Resistance of Natural-Synthetic Fiber Interply Laminate Hybrid Composites

Natural and synthetic fibres have emerged in high demand due to their excellent properties. Natural fibres have good mechanical properties and are less expensive, making them a viable substitute for synthetic fibers. Owing to certain drawbacks such as their inconsistent quality and hydrophilic nature, researchers focused on incorporating these two fibres as an alternative to improve the limitations of the single fibre. This review focused on the interply hybridisation of natural and synthetic fibres into composites. Natural fibres and their classifications are discussed. The physical and mechanical properties of these hybrid composites have also been included. A full discussion of the mechanical properties of natural/synthetic fibre hybrid composites such as tensile, flexural, impact, and perforation resistance, as well as their failure modes, is highlighted. Furthermore, the applications and future directions of hybrid composites have been described in details.

“…Cashmere and wool are natural animal fibers and important raw materials in the textile industry [1]. However, cashmere is rarely produced compared to wool, and cashmere is lighter, softer, and warmer than wool, thus these make the price of cashmere tens of times the price of wool.…”

Cashmere and wool are both natural animal fibers used in the textile industry, but cashmere is of superior quality, is rarer, and more precious. It is therefore important to distinguish the two fibers accurately and effectively. However, challenges due to their similar appearance, morphology, and physical and chemical properties remain. Herein, a terahertz electromagnetic inductive transparency (EIT) metasurface biosensor is introduced for qualitative and quantitative identification of cashmere and wool. The periodic unit structure of the metasurface consists of four rotationally symmetric resonators and two cross−arranged metal secants to form toroidal dipoles and electric dipoles, respectively, so that its effective sensing area can be greatly improved by 1075% compared to the traditional dipole mode, and the sensitivity will be up to 342 GHz/RIU. The amplitude and frequency shift changes of the terahertz transmission spectra caused by the different refractive indices of cashmere/wool can achieve highly sensitive label−free qualitative and quantitative identification of both. The experimental results show that the terahertz metasurface biosensor can work at a concentration of 0.02 mg/mL. It provides a new way to achieve high sensitivity, precision, and trace detection of cashmere/wool, and would be a valuable application for the cashmere industry.
