New sustainable fibers for a circular textile industry
New sustainable fibers for a circular textile industry: There are many innovations currently being developed in the textile industry to promote the use of more sustainable resources against those who are a truly serious risk for the best conservation of the environment, such as oil or leather.
Today we are going to talk about 5 new fibers for a more sustainable fashion:
- Spider silk
- Orange peels
- Pineapple leaves
- Cow dung
- Wood pulp
Spider silk is surprisingly one of those new materials that are beginning to be used in fashion design and subsequent manufacturing. The main “ingredient” for the manufacture of this silk is protein, transforming it into fibers.
As main properties we can highlight that it is very resistant , as well as elastic , also having a fundamental characteristic, in these lines that concern us, it is biocompostable . This has led many researchers to try to replicate this process in the laboratory, because the spiders are territorial and cannibalistic.
Orange peels, another resource that also begins to find its space in the field of fashion. When talking about food waste, fruits unfortunately find a prominent place, with many pieces ending up in our garbage can daily. So looking for another alternative to the well-known compost is possible.
For this “citric cellulose is extracted and converted into a fiber, trying to have a similar result to silk”. It emerged as a prototype a few years ago in Italy. And since then it has been trying to promote its use in favor of better environmental care, involving all industrial and social spheres.
Pineapple leaves , as with the orange peel, are organic waste, this time, generated in the agricultural field that instead of ending up becoming waste. It is given added value with a future in textile production, emerging as an alternative to the well-known leather. This innovation is called “Piñatex”, developed by Dra. Carmen Hijosa, Asturian from Salas and settled for many years in Irlanada. Its production consists of extracting the fibers from these sheets, cutting them into layers, later converting them into a mesh. And later facilitating their transformation into a fabric very similar to leather, resistant and that can have different textures.
Wood pulp fourth example that we highlight in the use of sustainable resources in textile production. For this, a sustainable planting of trees is required to ensure. First of all, a production process that is respectful of the environment. Thus being able to obtain the cellulose fiber by dissolving the wood pulp. It comes to compare with high quality fabrics such as silk and cotton.
Cow manure from intensive dairy farming for the production of bioplastic and sustainable fibers, a last resort that we discuss today. The idea is due to a Dutch designer Jalila Essaïdi and the method is known as Mestic.
The manure of these cows is made up of 35% cellulose, enough to meet the demand for fibers and an interesting alternative to replace cotton. Which is currently the crop with the greatest environmental impact.
