The HEMP-HQ project, “RESEARCH ON NEW HIGH-
, HIGH-QUALITY HEMP FABRICS FOR DECORATION,” developed by RIOMA S.L., has been co-financed by the
, the European Regional Development Fund (ERDF), and the Center for Industrial Technological Development
(CDTI).
OBJECTIVES:
The overall objective of this project was the research and development of new processes for
the manufacturing, functionalization, and finishing of hemp fabrics and their blends (primarily
hemp and wool), resulting in high-quality, sustainable fabrics intended for the home décor and
upholstery sectors. In the second phase of the project, particular emphasis was placed on the application of digital printing
using polyurethane pigment inks, the development of designs through laser engraving, and
the incorporation of advanced functional properties, such as antimicrobial capabilities and improved
lightfastness.
The work carried out has led to the development of new fabrics intended primarily for
upholstery, curtains, and interior decoration applications, characterized by a high degree of design flexibility,
excellent aesthetic qualities, and technical performance tailored to the industry’s requirements.
In addition, the processes of digital printing, laser engraving, tumbling, and the application
of advanced chemical finishes have been optimized, resulting in materials with significantly improved texture, drape,
strength, and durability under normal use.
RIOMA conducted studies and optimized the spinning and weaving processes for new
natural fiber blends, as well as studying the fabric preparation stages prior
to printing. Subsequently, the yarn dyeing processes
were researched and developed, along with digital printing on unbleached fabrics using polyurethane pigment inks, laser engraving
, tumbling, and the application of advanced chemical finishes. Complementarily, specific treatments were developed
to enhance the antimicrobial capacity and lightfastness
of the resulting fabrics, with their efficacy validated through standardized tests.
It should be noted that, throughout all stages of the project, the optimal configurations were defined and validated
at both the laboratory and pre-industrial scales, enabling the establishment of robust,
reproducible processes that are compatible with the stated sustainability objectives. The fabrics developed
successfully met the technical requirements set forth in the project report, including
the objectives related to wash, rub, and light fastness, as well as those pertaining to
antimicrobial functionality, hand feel, drape, and aesthetic quality.
Thanks to these results, RIOMA has expanded its range of sustainable products through the
development of new high-value-added hemp and wool fabrics, along with technologies such as
digital printing and laser engraving, which have helped enhance the sustainability of the products
developed and reduce their environmental impact.
That is why this project has been successfully completed, resulting in new, sustainable, functional, and high-value-ad
e fabrics that allow RIOMA to strengthen its position as
an innovative company and a leader in the development of advanced textiles for decoration and upholstery.
