The prickling is a problem in natural animal fiber, but there is no an allergic but a mechanical problem. In this manner, dehairing is a pre-textile process that permit extract objectionable (coarse) fiber and then improve the fabric quality. The objective of this study is to determine the variables of the fiber diameter and fiber frequency may be indicative of the effect of the dehairing on prickliness of Llama fiber fabrics that can be detected by consumers of knitting fabric garments. The variables that panellists consumers can detect when comparing dehaired and non-dehaired fibres are: overall fibre diameter (in fabric and surface), fibre diameter coefficient of variation (significate in yarn); fibres coarser than 30 μm (in yarn and surface); coarse fibre by weight (in yarn and in surface); coarse fibre mean diameter (in yarn and in surface). These differences are explained mainly b...

In this paper we intends to analyze the physical attributes that determine the comfort of fabrics made of South American Camelid fibers (Lama and Alpaca), the effect on their value and their possible mechanical and/or genetic solutions. While emphasis has always been on mean fiber diameter, the fiber frequency exceeding 30 microns has a key role in quality. This is essential for light fabrics, where the effect of prickle plays a critical part in consumer´s choice. Yet the genetic solution of the problem lies in the slow selection response. Dehairing provides an immediate solution, though excessive fiber breakage should be addressed. It is concluded that the textile fiber quality of South American Camelids is promissory if the presence of objectionable fibers is solved, resulting in a tolerable frequency for consumers (<3%). This process could be explored via genetic selection or applyin...

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 focuse...
