The Valencian Institute of Business Competitiveness (IVACE) has awarded us a grant of €39,452.70, which is financed by the European Regional Development Fund (FEDER) in a percentage of 50% through the FEDER Operational Program of the Valencian Community, for this project with the title "R&D OF COMPOSTABLE TECHNICAL YARNS OF POLYLACTIC ORIGIN" and file number IMIDTA/2021/15 submitted to the PIDI-CV program.
The objective of this project has been the development of a new range of compostable technical yarns from polylactic acid (PLA) by means of DREF spinning, being possible through the exhaustive search carried out to obtain a polylactic acid (PLA) fiber that had technical properties suitable for DREF spinning together with different modifications made to the machinery. The new PLA technical yarns seek, in addition to being compostable, to comply with other characteristics of the market they were intended for.
The new technical PLA yarns, in addition to being compostable, have other characteristics of market for which they are intended: handles for paper bags and agro-food
Much of this project has been due to the study of different compositions of the coating/core structure, together with the study of various proportions to obtain the optimal coating for the final objective of the project with polylactic acid fiber (PLA) with biodegradable fibers ( viscose and bamboo). Once both studies were carried out, seeking to meet the objective of the project, different weight/length ratios of the thread were studied, more commonly called the thread count, together with different bends and twists to be carried out. With this, it was intended to achieve different values in the objective parameters to be met, choosing the most suitable yarn for its final destination.
Finally, the project was successfully completed, being of great interest to different clients of the company, seeking to increase the use of technical yarns with compostable material.
