Inventor: BAEKELANDT CARL, TUYTENS MANU, INGHELBRECHT KURT
The present invention relates to a textile article, a method for managing information about a textile article and a system for managing information about a textile article. The invention is advantageous due to an increased traceability of the textile article, as well as an improved processing prior to a recycling or reuse process. In addition, the present invention is extremely suitable for selectively communicating textile information to a producer and consumer side in a supply chain or life cycle of the textile article.
Multilayered textile as/for durable and washable high-performance filtration media and method of assembling thereof
Patent number: WO2021/212219
Publication date: 2021-10-28
Applicant(s): SECOURS MICHELLE
Inventor: SECOURS MICHELLE, DUMAS-QUESNEL MONIQUE, PALANGIÉ ANTOINE
A list of highly suitable textiles and a method to combine them into a durable reusable filtration medium with high particles filtration efficiency (PFE) and breathability that lasts over 50-75 laundering cycles. Filtration medium achieves PFE only through mechanical means, without fragile and harmful physicochemical pre-treatments. Different textiles are assembled considering their individual breathability and their complementary in terms of PFE on different particles' sizes to achieve good breathability and high PFE on a large range (20nm-4μm) after many laundering cycles, or several layers of the same textile are paired, while varying the fibers' orientation and dimensions in each layer to increase efficiency. This assembling method highly improves PFE, service life and performances' stability of the filtration medium by addressing structural weaknesses linked to anisotropy in each layer, and by protecting their fine fibers from mechanical wear and clogging through a face-to-face closed filtration cell-type pairing.
Plastic elements produced 100% with plastic residues of rejection and transparent luminescent coating on the surface
Patent number: ES1280540
Publication date: 2021-11-02
Applicant(s): RODRIGUEZ BARREIRO CELSO, SAINZ PEREZ JOSE VICENTE
Inventor: RODRIGUEZ BARREIRO CELSO, SAINZ PEREZ JOSE VICENTE
Plastic elements produced entirely from rejected plastic waste (not recyclable in other processes) (1) with transparent luminescent coating (2) on the surface. The mixture of plastic elements from which we obtain the raw material comes from the green or gray container (rest fraction) and the yellow container (non-recyclable fraction) or from the agricultural, livestock and industrial sectors. Being the main plastic polymers used HDPE, PELD, PP, PS, ABS, PET AND POLYAMIDES mainly without neglecting others. The transparent coating (4) (Epoxy base, polyurethane, elastomer, acrylic, polyester, methacrylate or other transparent liquid element for this purpose) incorporates an additional photo-luminescent or luminescent component transparent in the dark (3), the coating manifests in the dark a high luminescence showing the surface characteristics of the element or part on the applied surface.
Use of lytic polysaccharide monooxygenases, enzymatic composition containing same, and degradation method for plastic polymers
Patent number: WO2021/232124
Publication date: 2021-11-25

Inventor: MURAKAMI MÁRIO TYAGO, RIBEIRO CORRÊA THAMY LÍVIA
The present invention relates to the novel activity of the enzymatic composition containing lytic polysaccharide monooxygenases (LPMOs) that are bacterial (Auxiliary Activity 10, AA10) and/or fungal (Auxiliary Activity 9, AA9) for degrading polyethylene terephthalate (PET) and related plastic polymers. The genes that encode KpLPMO10A (AA10) and AfLPMO9A (AA9) were isolated from Kitasatospora papulosa and Aspergillus fischeri microorganisms, respectively. Methods such as atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) detected alterations in the superficial chemical composition and morphology of the PET found in liquid bottles when treated with LPMOs. The gentle temperature conditions used during the LPMO-PET reaction suit the use of these enzymes to help canonical enzymes (PETases) deconstruct plastics, which is beneficial for the circular economy for PET.
