The aim of this review is to address the issue of textile-origin microplastics and to provide possible solutions that can be propose through a scientific and development program. The constant expansion of textile production and consumption, driven by population growth and the ubiquity of fast fashion, has triggered environmental contamination resulting from the release of fiber fragments during the washing and use of clothing and household textiles. These fragments, ranging in size from 1 μm to 5 mm, pose a novel source of pollution that not only threatens the health of aquatic animals when ingested but also risks human food safety by infiltrating the food chain. Despite the growing awareness of the environmental impacts of these plastic microfibers (MP) from synthetic textiles, this study departs from conventional actions focused on mitigating microplastic pollution. Instead, it focuses on proposing specific measures to reduce MP emissions and addresses the even greater challenge of replacing these plastic microfibers with animal-origin textile fibers. This approach emerges as a promising and sustainable alternative to counteract the negative environmental impact of the contemporary fashion industry. The essence of this challenge lies in determining the competitiveness of animal-origin textile fibers against MP. To achieve this goal, specific actions are proposed, including the need to reduce both the environmental impact and costs associated with processing animal fibers. The study also emphasizes the importance of effectively highlighting the biological and textile advantages of these fibers to encourage their acceptance and adoption in the competitive textile market. This project addresses concrete strategies to promote the use of animal-origin textile fibers. It suggests optimizing the cleaning process and genetically improving these fibers, considering key aspects such as quality and color. The research also highlights the potential contribution to sustainability certification and well-being associated with the use of animal-origin textile fibers, providing a solid foundation for their adoption in the textile industry. In conclusion, this work not only departs from traditional measures focused on microplastics to address MP release but ventures into more ambitious territory by proposing increased use of animal-origin textile fibers as a path to a more sustainable fashion. Specific actions are outlined to enhance the competitiveness of these fibers in the current market, emphasizing their potential contribution to reducing textile pollution and thus strengthening the transition to more environmentally responsible practices in the fashion industry.
Comparative analysis of key fiber characteristics in white pima cotton (Gossypium barbadense L.): Native accessions from the Peruvian Amazon

The fiber quality of cotton (Gossypium barbadense L.) native to the Peruvian Amazon region is one of the most versatile and essential natural fibers in the Peruvian textile industry. There is little information about the fiber quality traits of cotton genotypes native to the Peruvian Amazon region. This study investigated the fiber quality traits of Peruvian Pima cotton accessions native to the Amazon region of the La Convención Province, Cusco, Peru, to determine the lines with the greatest potential for improving fiber quality in cotton genetic breeding programs. A total of 14 cotton accessions with white fiber color, being 12 accessions of G. barbadense L. (Pima cotton) and two accessions of Gossypium sp. (unknown cotton), were analyzed. The fiber properties determined using the high volume instrument method included seven characteristics. All fiber properties were classified into five quality classes. The data on fiber quality properties were subjected to distribution, correlation, and canonical variable analysis. The results of fiber quality properties showed that the two accessions of Gossypium sp. (unknown cotton) can be promising options to be used as high-quality fiber progenies in crop genetic breeding programs or can be cultivated by regional farmers for the purpose of producing cotton with high fiber quality. Future investigations could utilize other methods of fiber quality analysis and compare the fiber quality of these cotton accessions native to the Peruvian Amazon region with other cotton species grown worldwide to improve the understanding of Pima cotton fiber quality and its applicability in different contexts of the textile industries.
Deciphering the fiber quality of Gossypium barbadense L. var. brasiliensis in La Convención, Cusco, Perú
(BioMed Central Ltd., 2024-07-02) Morales Aranibar, Luis; Canto Sáenz, Manuel Antonio; Morales Aranibar, Carlos Genaro; Nieves Rivera, Marite Yulisa; González Aguilera, Jorge; Steiner, Fábio; Bardiviesso, Diógenes Martins; Zuffo, Alan Mario
The quality of cotton fiber determines its value in the textile market, influencing agricultural profitability and the efficiency of textile processing. The selection of genotypes with superior fibers is a key factor for genetic improvement programs seeking adaptability and sustainability in the face of climate change. This demonstrates the strategic importance of this plant for sustainable agriculture and the global textile industry. The objective of this research was to decipher the fiber quality of Gossypium barbadense var. brasiliensis in the native Amazonian communities of La Convencion, Cusco-Peru, and to evaluate other critical aspects of native cotton that have not yet been identified. The methodology included non-probability sampling for accessibility, qualitative and quantitative analyses, and multivariate analyses. The fiber length (mm), micronaire index (maturity/fineness), fiber strength (gf/tex), length uniformity index (%), fiber elongation (%), maturation index (%), and short fiber index (%) were the fiber characteristics evaluated using the HVI method in cotton genotypes.
Estimación de la heredabilidad de seis caracteres de calidad de fibra de alpacas huacaya del INIA Puno
(Göttingen University Press, 2019-07-02) Mamani Cato, Rubén Hebert; Huanca Mamani, Tedosio; Pineda Serruto, Martín Equicio; Naveros Flores, Mary Luz; Gallegos, R.
El objetivo fue estimar las heredabilidades de seis caracteres de calidad de fibra de alpacas Huacaya a la primera esquila del banco de germoplasma del Instituto Nacional de Innovación Agraria, ubicado en el departamento de puno a una altitud de 4,200 metros en la zona agroecológica de puna seca. La base de datos constó de 9,114 registros de fibra y fueron analizados con el analizador óptico del diámetro de fibra (OFDA, IWTO-47-95) en el laboratorio de fibras del IVITA Maranganí. Para estimar los componentes de varianza del diámetro de fibra, desviación estándar del diámetro de fibra, factor de confort, coeficiente de variabilidad del diámetro de fibra, longitud de mecha y peso vellón se utilizó el modelo animal unicaracter y = Xb + Zu + e, donde y es el vector de observaciones, b es el vector de efectos fijos (sexo, color y mes-año de esquila) la edad en días se consideró como covariable lineal, u es el vector que representa el efecto genético aditivo, e es el vector de residuales; X y Z son las matrices de incidencia de efectos fijos y aleatorios respectivamente. Los componentes de varianza fueron estimados por el método de Máxima Verosimilitud Restringida (REML) utilizando el programa VCE versión 6.0.2. La heredabilidad estimada para el Diámetro de fibra fue de alta magnitud 0.540±0.087; para el resto de caracteres fue de media magnitud siendo para la Desviación estándar 0.311±0.089, Factor de confort 0.278±0.077, Coeficiente de variabilidad 0.291±0.089, Peso vellón 0.158±0.027 y Longitud de mecha 0.268±0.081. Se concluye que es posible obtener una buena respuesta a la selección para los seis caracteres de calidad de fibra en alpacas Huacaya.
