AB  - This work aimed to obtain jute fabrics suitable for the production of inexpensive technical textiles by using simple alkali treatments. The influences of alkali concentration (1–17.5 % NaOH) and treatment duration (5–30 min) on the fabrics’ compression properties, abrasion resistance, and sound absorption coefficient were studied in detail. With increasing the treatment severity, the fabric compressibility decreases by 19.6–33.9 % due to increased fabric compactness. In parallel, the fiber crystallinity index and hemicellulose content decrease, while the fibers’ interfibrillar regions become less dense and less rigid contributing to 19.0–27.0 % better recoverability after compression. The mercerized fabrics possessed a notably lower mass loss (4.1–5.9 %) after 750 abrasion cycles compared to the other investigated fabrics (18.9–30.9 %), which could be ascribed to the higher friction forces existing between the yarns within the mercerized fabrics and between the fibers within the yarns, as well as higher elongation at maximum force. In the case of the fabrics treated for 5 or 15 min with different NaOH concentrations, their mass losses during abrasion decrease with increasing the elementary fiber liberation, while the sound absorption coefficients increase with increasing the fabric compactness. Mercerized fabrics are capable of absorbing about 28 % to 2.7 times (at 990 Hz) and 2.0 to 2.4 times (at 4090 Hz) higher mechanical sound energy compared to the untreated fabric. The jute fabric mercerized during 30 min could be used for the production of carpet backings, while those mercerized during 5 min is the most suitable for the production of sound-absorbing materials.

AB  - In the present research, folding of yarns was applied as a method for designing thermal transport characteristics of hemp-based knits. The rib-knitted fabrics were made by combining one of two cotton two-folded yarns (differing in folding twist) with one of the two complex hemp yarns. The parameters describing the thermal properties in the steady-state and transient regimes of heat transfer were determined. The results indicated that the packing density of the fibers in the yarn plays a crucial role in the heat conduction through the fabric. The two-assembled hemp component appeared to be the main heat conductor in the knitted fabrics containing it. Between the knits composed of the two-folded hemp and two-folded cotton yarns, that having two-folded more twisted cotton yarn as a component was characterized by higher thermal conductivity. The higher thermal conductivity resulted in higher thermal absorptivity, but not necessarily in higher thermal diffusivity, as the increased volumetric heat capacity may limit the speed of heat spreading through the fabric. Therefore, the knits containing two-assembled hemp yarn differed in thermal diffusivity despite their similar thermal conductivity. Both knits with the two-folded more twisted cotton yarn as a component had similar thermal diffusivity despite their different thermal conductivity.

AB  - Low-temperature plasma is widely used in many surface treatment technologies for modifications of the physical properties of different polymeric materials. In the present work, we have examined the modification of acoustical properties of natural cellulose materials (cotton, hemp) by the radio-frequency argon plasma. We have observed an increase of the sound absorption coefficient due to the plasma treatment for certain range of applied powers. An analysis of elementary processes which happened during plasma-material interaction was conducted. Additional analyses related to material characterizations were performed in order to resolve structural and chemical changes of plasma treated materials. The micro-mechanical modification of treated materials, which happened upon the retrieved structural and chemical changes, was related to the modification of its acoustical properties in order to explain the observed effect.

AB  - The thermal parameters that describe the transient response of cellulose textile fabrics due to the changes in physiological and environmental conditions were analyzed. Starting from the specific heat of the knitted fabrics determined by a new experimental method based on Newton's cooling rate law, and previously determined thermal conductivity of the knits, their thermal diffusivity and thermal effusivity (absorptivity) have been determined. According to the results obtained, it can be concluded that the structure of the knitted fabrics is responsible for their transient thermal response through thermal conductivity, whereas the composition of the knits influences their dynamic thermal behavior through specific heat. Hemp based textile fabrics are proved to be at a comparable level to other cellulose fabrics from the viewpoint of thermal behavior during the dynamic stage of heat transport.
