Therefore, the incorporation of cheaper recycled raw materials into the particleboard structure is welcome and the economic costs of their production are reduced. The aim of this research was to find out the possibilities of processing recycled municipal waste in a commonly produced structure and incorporating it into the particleboard in an optimal proportion. Another goal was to determine the effect of the recycled material proportion on the selected particleboard physical and mechanical properties so that boards can be used for common furniture interior applications. Single- layer particleboard with 10%, 15%, 20%, 25% and 30% of recycled waste were produced, followed by three-layer boards with the proposed optimal 15% recycled waste in their core layer. The following properties of particleboard were tested: flexural strength, swelling, water absorption, density (according to the relevant provisions of EN). The effect of the proportion of recycled waste on board properties was manifested in comparison with the control samples, the reduction of the mechanical values was moderate. The bending strength values of three-layer particleboards with a 15% recycled waste content in their core layer were at an average level of 9.7 N/mm2. The required level of bending strength of 11 N/mm2 was not achieved. It was caused by the recycled elements manufactured shapes which were not slim enough and, in combination with the slim wood particles, worsened the properties of the manufactured particleboard. Adjusting the recycled elements' shape and pressing conditions makes achieving the standard required values of the particleboard properties possible.

The effect of selected factors on the mechanical properties of the seams for upholstery covers made of synthetic leatherAut.údajeAnna Vilhanová, Nadežda LangováPreklad názvupodnázvu : Vplyv vybraných faktorov na mechanické vlastnosti švov čalúnníckeho poťahového materiálu zo syntetickej kožeAutorVilhanová Anna TUZDFNDV - Katedra nábytku a drevárskych výrobkovSpoluautoriLangová Nadežda TUZDFNDV - Katedra nábytku a drevárskych výrobkovZdroj.dok.Acta Facultatis Xylologiae Zvolen : vedecký časopis Drevárskej fakulty.

The stitches of the cover layers are considered a critical place of the upholstery, in which deformations and possible damages are most visible. The paper is focused on synthetic leather, which is considered a composite, ecological and sustainable material. The bearer of the mechanical properties is the reverse side formed by the underlying textile. The focus is put on the influence of stitch length (4, 5, 6 mm) in the weft and warp direction of the underlying fabric of the synthetic leather. The stitched joint has higher strength and stiffness in the warp direction, but its efficiency is lower compared to the load in the weft direction. It means that the stitched material carries a greater load than the thread-connecting material. Joints with longer stitches hold the fabric together with less tension. The sewing thread carries higher loads with a longer stitch length. The results of joint strength and failure show that when creating cutting plans, it is advisable to orient the parts of the covering material so that the joint is stressed in the direction of the warp due to the user's load.
