“…As a result, the number of research works that have studied the novel applications of feather waste in various areas has recently increased [6][7][8][9][10][11][12][13][14][15]. In terms of the thermal insulation capability, feathers are considered a sustainable thermal insulation material that can be used in many thermal insulation applications due to its low thermal conductivity, ranging from 0.024 W/(m. K) to 0.034 W/(m. K), depending on the feather's types [16]. This low thermal conductivity range is due to the feather's chemical composition and microstructure, which effectively traps air and produces a good thermal barrier.…”

Recently, the world has been moving towards reusing wastes in many industrial applications, such as buildings and automotive, to eliminate the environmental pollution impact due to increasing waste worldwide. Besides, waste reuse also leads to cost savings and improves sustainability. Therefore, this short review aims to present and discuss the recently used methods of utilizing feather waste as sustainable and renewable insulation instead of traditional petroleum-derived materials. The father's low thermal conductivity ranges from 0.024 W/(m. K) to 0.034 W/(m. K), and it's chemical composition and microstructure effectively trap air and produce a good barrier. So, feather waste fibers can be used as an effective thermal and acoustic insulation material with the same or better performance than commercially available products. However, several significant barriers and limitations associated with the manufacturing process of feathers insulations were identified in this review. These limitations make the commercial development of insulation materials based on feather waste a challenge. They need to be appropriately addressed to realize the potential of feather waste as a reliable insulation material.

“…Feathers are one of the most effective thermal insulation materials, with thermal conductivities ranging from 0.024 W/(m K) and 0.034 W/(m K) depending on the type of feather [1]. The low thermal conductivity of feathers results from their chemical composition and microstructure, which effectively traps air and produces a highly effective thermal barrier.…”

Poultry has become the primary source of dietary protein consumed globally and as a result the by-product feathers are an increasingly problematic industrial waste. Developing a circular economy for feathers is, therefore, an important research area that provides an opportunity to make use of the unique combination of properties of this abundant natural material. This paper reports on the thermal properties of novel feather-based thermal insulation materials. Waste feathers were collected, cleaned and processed into fibres, which were then used to form air-laid nonwoven materials. These have a high fibre content and exploit the excellent natural thermal insulation properties of feathers. The performance of the novel materials developed are tested in order to outline the influence of temperature and density on thermal conductivity and dynamic water sorption. Results are compared to a range of commercially available thermal insulation materials for buildings manufactured from denim, hemp, sheep wool, PET and mineral wool. It was found that air laid feather-fibre fabrics have comparable performance to other fibrous materials and have a thermal conductivity of 0.033 W/(m K) for samples with a density of 59 kg/m 3. This is due to the low thermal conductivity of feather fibres and the void structure formed by air-laid processing that effectively traps air. These materials additionally offer improved sustainability credentials as they are derived from a readily available waste that is generally considered to be unavoidable. The paper concludes by highlighting the significant technical and commercial barriers that exist to using waste feathers in thermal insulation products and suggests areas for further research that can exploit the unique properties of feathers.

“…However, this type of plasma has only occasionally been reported for use in modifying natural, fluffy materials such as goose down [15,16]. Since the goose down is considered as the best filling material in textile products [17], due to the excellent thermal insulation and fill power (loft) [18][19][20], research has begun towards the elimination of the main drawbacks of down, i.e., moisture absorption and mold growth. These drawbacks lead to an almost complete loss of the thermal insulation properties of down with a loss of loft and a significant deterioration of its suitability, as well as environmental health risk by opening the way for the growth and development of allergenic (harmful) fungi [21][22][23].…”

Artificial Superhydrophobic and Antifungal Surface on Goose Down by Cold Plasma Treatment

et al. 2020

Plasma treatment, especially cold plasma generated under low pressure, is currently the subject of many studies. An important area using this technique is the deposition of thin layers (films) on the surfaces of different types of materials, e.g., textiles, polymers, metals. In this study, the goose down was coated with a thin layer, in a two-step plasma modification process, to create an artificial superhydrophobic surface similar to that observed on lotus leaves. This layer also exhibited antifungal properties. Two types of precursors for plasma enhanced chemical vapor deposition (PECVD) were applied: hexamethyldisiloxane (HMDSO) and hexamethyldisilazane (HMDSN). The changes in the contact angle, surface morphology, chemical structure, and composition in terms of the applied precursors and modification conditions were investigated based on goniometry (CA), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy in attenuated total reflectance mode (FTIR-ATR), and X-ray photoelectron spectroscopy (XPS). The microbiological analyses were also performed using various fungal strains. The obtained results showed that the surface of the goose down became superhydrophobic after the plasma process, with contact angles as high as 161° ± 2°, and revealed a very high resistance to fungi.
