A novel green approach for dyeing polyester using glycerine based eutectic solvent as a dyeing medium

open access: yesHeliyon, 2019
In the past decade, water scarcity has become major concern and is going to be reality in future too. At the same time textile is necessity which needs a billion liters of fresh water for its processing.

Possibilities and Conditions of Developing Mulberry Silkworm Rearing in Poland, Especially for Purposes Related to the Production of Natural Cosmetics Based on Silk Proteins Obtained from Silkworm Cocoons

open access: yesJournal of Natural Fibers, 2022
Sericulture is associated primarily with the production of cocoons for textile purposes. However, the widespread availability of synthetic fibers caused a decline in interest in natural fabrics, including silk.

Effective Use of Flax Biomass in Biorefining Processes

open access: yesApplied Sciences, 2023
Flax is one of the few plants that are entirely a source of raw materials for further production. Promising directions for the use of flax biomass may be the production of bioenergy in the form of 2G biofuels and the production of “green” composites. The

On fibre spaces in which the fibre is contractible

open access: yesCommentarii Mathematici Helvetici, 1955
Les AA. établissent tout d'abord un théorème dont nous ne mentionnerons que le cas particulier suivant: Soient \(X\) un espace fibré, localement compact, séparable métrique, rétracte absolu de voisinage, localement trivial, de base \(Y\), fibre \(A\), projection \(p\). Si \(A\) est contractile en un point dans \(X\), alors \(A\) est un \(H\)-espace. La

Effective Utilisation of Halophyte Biomass from Saline Soils for Biorefinering Processes

open access: yesMolecules, 2021
The salinity of European soil is increasing every year, causing severe economic damage (estimated 1–3 million hectares in the enlarged EU). This study uses the biomass of halophytes—tall fescue (grass) and hemp of the Białobrzeskie variety from saline ...

Recovery and reuse of discontinuous carbon fibres by solvolysis: Realignment and properties of remanufactured materials [PDF]

open access: yes, 2016
Discontinuous carbon fibre tows were recovered after solvolysis of an aeronautic type composite made with RTM6 epoxy resin. A Sohxlet extraction method was used to quantify the organic residue on the fibre tows and showed that less than 3 wt% was ...

Computational studies of light acceptance and propagation in straight and curved multimodal active fibres [PDF]

open access: yes, 2002
A Monte Carlo simulation has been performed to track light rays in cylindrical multimode fibres by ray optics. The trapping efficiencies for skew and meridional rays in active fibres and distributions of characteristic quantities for all trapped light ...

Dual morphology (fibres and particles) cellulosic filler for WPC materials [PDF]

open access: yes, 2016
Wood-plastic composites (WPC) were fabricated by using a polyethylene (PE) matrix and filling it with wood flour in the amount of 30 wt.%, and compared with the same composites with further amount of 10 wt.% of cellulosic recycled fibres added.

Crystal structure determination of a lifelong biopersistent asbestos fibre using single-crystal synchrotron X-ray micro-diffraction

open access: yesIUCrJ, 2021
The six natural silicates known as asbestos may induce fatal lung diseases via inhalation, with a latency period of decades. The five amphibole asbestos species are assumed to be biopersistent in the lungs, and for this reason they are considered much ...
