- the linen yarn comes from a natural fiber that brings comfort, versatility and durability. Since its planting, through the preparation of the fiber and the final finish of the fabric, the impacts on the environment are minimal. Its cultivation requires up to twenty times less water than cotton and minimal amounts of fertilizer, in addition, flax does not harm the soil, being easily incorporated into the rotation cycle of other crops, the processing of its fibers is done with low use of electricity and relies on with the help of natural agents, such as rain and sun, and practically all residues from its production are used by other industries, such as cosmetics, food and paper.

Instead, it uses biodegradable and or compostable and or ecological and or sustainable and or synthetic filament, replacing the synthetic and artificial cut fiber of polyester and polyamide, creating, protecting and giving more comfort to people with an ecological and or sustainable mixed yarn.
- Another objective was to provide a mixed yarn production process that preferably uses biodegradable filaments and/or sustainable filaments and/or filaments that can be dyed in their mass, eliminating water bath dyeing, making it less polluting and using much less water in the dyeing process of the fabrics, in addition, the mixed yarn leaves the process ready, without the need for bath dyeing, only finishing.

- Another objective was to provide a process for the production of biodegradable and sustainable mixed yarns.
- Another objective was to provide a yarn production process that makes it possible to combine spun yarns of 100% organic cotton with biodegradable, ecological and or sustainable and or technological filaments, and or polyester, in the percentage of local federal law and thus defined as an organic product.
- Another objective of providing a mixed yarn production process is that the production process for mixed, ecological and or sustainable yarns is a sustainable process, in combining mixed yarns by compressed air, ensuring the adequate removal and disposal of existing oligomer molecules, other molecules and other fibers during the process, thus avoiding soil and environmental contamination and risk to respiratory health.
- Another objective was to provide a production process for mixed yarns that enables easy adaptation of the process in the spinning mills or textile industries. Mixed biodegradable and or sustainable yarns are used in conventional and unconventional process machinery connected to other machines or in winding machines for textile industries.

- PRODUCTION PROCESS OF ECOLOGICAL, SUSTAINABLE MIXED YARNS AND MIXED YARNS OBTAINED, according to claim (1) characterized for providing a mixed yarn production process is that the production process for mixed, ecological and or sustainable yarns is a sustainable process, in combining mixed yarns by compressed air, ensuring the adequate removal and disposal of existing oligomer molecules, other molecules and other fibers during the process, thus avoiding soil and environmental contamination and risk to respiratory health.
- PRODUCTION PROCESS OF ECOLOGICAL, SUSTAINABLE MIXED YARNS AND MIXED YARNS OBTAINED, according to claim (1) characterized for reaching new pressures of compressed air, being able to use the minimum pressure of compressed air, saving energy exerted on and around the spun yarns, obtaining a wide effect of mixed blends in ecological and or sustainable yarns, with superior physical and chemical characteristics of a new technological and ecological and or biodegradable and or compostable yarn.
- PRODUCTION PROCESS OF ECOLOGICAL, SUSTAINABLE MIXED YARNS AND MIXED YARNS OBTAINED, according to claim (1) characterized in that the mixed yarn does not contain synthetic and artificial cut fiber of polyester and polyamide, one of the biggest causes of ocean contamination by plastic microparticles, which currently triggers an unprecedented contamination affecting the entire human food chain. Instead, this sustainable process and product uses biodegradable and or compostable and or ecological and or sustainable and or synthetic filament, replacing the synthetic and artificial cut fiber, an evolution of the intimate mixture of fibers, protecting the oceans and human beings and giving more comfort and technology to people with mixed ecological and or sustainable or biodegradable and or composable and technological yarns.
