The dehairing process is a fiber cleaning process and consists of separating objectionable coarse fibers and plant and mineral contaminants from the fine fibers as efficiently as possible. This efficiency is determined by the fiber type removal/retention rate (RR) and the fiber length shortening rate (FL). Up the present, in fiber from Llamas and Alpacas, the dehairing yield (R%) has been used as a commercial evaluation of the efficiency of the process. Efficiency is of greater commercial importance because it reflects the amount of desirable fiber that is actually obtained after the cleaning process has been performed. It also allows comparing technologies, number of passages and process costs. The objective of this work is to determine the efficiency of Llama and Huacaya Alpaca fiber dehairing carried out by AM2 technology based on the retention/removal (RR) and shortening (FL), taking into consideration different types of fibers (GF), types of fleece (TV), using methodology used in other fibersusing methodology and variables from studies with other fibers. The dehairing efficiency of the AM2 technology is similar in Llama and Alpaca fiber and slightly better than a similar technology used in cashmere fiber in Australia. In general efficiency fluctuates between 74-94%, in terms of desirable fine fiber recovery, for the textile process of these fibers. The variable defined as the fiber type removal/retention rate, is usable to correctly evaluate the fiber dehairing process of Llamas and Alpacas.

“…The main fiber features which play a central role in the effectiveness of mechanical dehairing are the hair rigidity (defined mainly by its diameter) and the hair length. In this regard, it is crucial to avoid the overlapping between the short and fine down fiber and the coarse and long guard hair [ 2 , 29 , 30 ].…”

In cashmere production studies, few trials have considered the guard hair features and their correlation with down fiber attributes. In this preliminary work, early observations on 158 one year old Chinese Alashan Left Banner White Cashmere goats were carried out. The aim was to describe the phenotypic correlation between the guard hair length and other fiber traits. The guard hair length was positively correlated with guard hair diameter and the down fiber length. Negative correlations were found between guard hair length and the coefficient of variation of guard hair diameter, between the guard hair diameter and its coefficient of variation, and between the down fiber diameter and the coefficient of variation of down fiber diameter. The body weight at first combing was not correlated with any of the other traits.

“…Regarding controversies in the scientific vertex: other groups promoted another strategy for cashmere development The CONICET and Universidad de Cordoba researchers aimed at maximizing raw fiber production. They promoted electric shearing for the international brokers as opposed to combing Cashmere and elaborating goods locally (Frank et al, 2018).…”

This work analyzes possible obstacles to developing new products or old merchandise using an innovative method. It will look into stakeholders of fine fiber and meat products from three distinctive socioecological systems. Through three case studies, we explore how natural resources management is connected to interests, values, and knowledge by stakeholders, which include government, the scientific community, and people with rural livelihoods. The government vertex is the national and provincial authorities involved with decision-makers at the national and provincial level. The Scientific-Technological vertex includes researchers from INTA, CONICET, and Universities. Rural livelihoods include livestock keepers, farmers, and local people with traditional knowledge. We will address the goods and services provided by two species of wild camelids and domestic livestock. The three cases have both similarities and differences in their focus and common ground of controversial spaces. They create complex networks of relationships and bonds leading to diverse outcomes. Top-down or bottom-up experiences hold distinct epistemology and research consequences, they affect rural livelihoods in various ways. For the three rural livelihoods, meaningful regulations should be endogenous social constructions. However, there are no longitudinal studies on the trajectories of these case studies. Long-term multispecies grazing opportunities are available for the three case studies. It depends on how stakeholders identify flexibility in their common ground to enable resilience to catastrophic events.
