The study assessed the changing of Ra, Rp, Rv and Rz roughness parameters of the sanded beech surface (Fagus sylvatica L.) as a function of different grit sizes and different measurement direction. The milled samples were ground with a belt sander BS-75 E-set from Festool with belt grit P60, P100 and P150. The sanding belts were Rubin 2 from Festool. Roughness was evaluated using a Keyence VHX-7000 digital microscope. The evaluation length of the roughness measurement was 12.5 mm (λc = 2.5 mm and λs = 8 mm). The R-parameters were measured in accordance with the latest standards ISO 21920 (2022) in the direction parallel to the grain, and in the direction perpendicular to the grain (profile). The paper proves the theoretical assumptions about the reduction of R-parameter values. The measurements showed that the sanded surface was less rough in the direction perpendicular to the grain at P150 sanding belt grit and in the grain direction at P100 grit.

Long-term operation of pulse-jet filters for wood dust. The study specifies the value of flow resistance and separation efficiency of filter material during long-term use in pulse-jet filters for wood dust. The experiments were carried out for one type of material working in two different filtration installations in one furniture factory. The bags were obtained from the installations after working for 67, 133 and 272 days, respectively. All tests were performed on the pilot-scale test stand under identical filtration conditions. Studies have shown that long-term filter material use increases airflow resistance and improves filtration efficiency. The range of these changes depends on the operating conditions of the pulse-jet filters. The obtained results made it possible to determine the properties of the long-term use of filter materials in various filtration conditions.

By introducing a new technological line for formatting and milling mass-customized door frames for wooden doors, PORTA KMI Poland with an industrial plant located in Ełk, Poland, conducted appropriate performance tests of the line to determine the production capacity during technological acceptance in order to check whether the assumed capacity was met before its technical acceptance takes place. The work describes how the processing time changes for frames with changed beam lengths from the reference length of 2028 mm to 2600 mm and for frames whose width has been increased from 127 and 147 mm to 500 mm. On this basis, an average time of 25.53 s was calculated for door frames with beams 2600 mm long and 28.1 s for door frames with a width of 500 mm. Efficiency was also calculated, which is 2.35 for frames with a changed beam length of 2.14.

Chosen flexural and hygroscopic properties of waste wood dust - polylactic acid biocomposite for 3D printing. The study shows chosen flexural and hygroscopic properties of PLA-waste wood dust biocomposite intended for use in 3D printing. Materials were mixed in 3 variants, differentiated by weight content of waste wood dust – 0%, 10%, 20% and 30% and extruded in a two-stage process using an extruder of original design. Variant without waste wood dusts was prepared as well. That filaments were then used to create samples using a 3D printer. For the printed samples chosen properties were tested i.e. MOE, MOR, water absorption and thickness swelling.It was found that waste wood dust does not significantly affect MOR and MOE. It was shown that it’s content negatively impacts the water absorption and thickness swelling. It was demonstrated that the tested material can successfully be used in 3D printing.

The effect of operational parameters on the creation of chip particles in the CNC finishing processingof wood-based materials. The object of this study was a comparison of created chips from the process of milling two wood-based materials: medium-density fiberboard, and particleboard, using a modern CNC 5-axis milling center. The materials in the form of blocks were milled at constant revolutions of the cutting tool (18,000 rev/min), with changeable variables of feed rates (8, 10, and 12 m/min), and width of cut (1, 2, and 3 mm). The size of created chips was measured by gravimetric weighing from sieving analysis of the retained volume of chips on sieves with pre-defined mesh sizes. The main emphasis was aimed at studying particles of chipsobtained in the finishing process of the milling below <0.125mm. However, the others are mentioned and discussed. Gravimetric differences of the retained volume of chip mass show that created MDF chips are mostly in the size range of <0.250 to 0.125 mm, and particleboard in the size range of <0.500 to 0.250 mm. Distribution of average values in dependence on different conditions shows a decreasing effect with increasing feed rate on the amount of very small chip particles in the volume of both materials. Increasing the feed rate can decrease the amount of very particles in the range below <0.125 mm in the volume of chip mass.

Characteristic of particles created by preparatory operations of the particleboard production process.The production of wood-based panels, taking into account material innovations, involves the need to adjust the operation of technological devices to the properties of basic and auxiliary materials. In this study, it was decided to check the particle sizes after sorting raw materials representing 3 groups: forest biomass – pine branches, agricultural biomass - oilseed plant straw, and post-production material. Fractions were taken from the 2.00 mm mesh sieve of a sorter for the core layer of the particleboard and the fractional composition was determined by sieve analysis. The average linear particle dimensions and bulk density of each lignocellulosic raw material were also determined. Due to the varying proportions, it is necessary to adapt the parameters of the technological operations to the specifics of the raw material being processed or to introduce guidelines for the selection of particle sizes guided by their actual average size. Studies have shown differences between the individual materials. This is particularly important, as proper preparation of the raw material translates into the quality of the boards produced from them and the efficiency of the entire process.

Influence of modification of aged spruce wood by in situ polymerization with ethyl methacrylate and methyl acrylate and paraloid B72 on color and water absorption. Wood is hydrophilic in nature, which creates problems such as dimensional instability and susceptibility to biological degradation. By using chemical modification, wood can be refined into new products with improved properties. Such a combination of wood and polymer is called a wood-polymer composite (WPC). The presented work compares the modification of aged wood by two methods. In situ polymerization with ethyl methacrylate and methyl acrylate with modification with Paraloid B72 solution. The determinants of the modifications carried out are percentage weight gain (WPG), color change and water absorption. Unmodified wood aged and unaged were the control samples. Also unaged and modified wood samples were prepared to compare results. The greatest change in color intensity and total color difference after the aging process was recorded for samples modified with Paraloid B72, and after UV light treatment - modified by the in situ polymerization. The in situ-modified samples had the lowest water absorption among aged samples, and Paraloid B72-modified samples had the lowest water absorption among unaged samples. The highest WPG was obtained from the aged samples modified by the in situ polymerization.

Selected features of medium density fiberboards produced with the use of plant binder. The aim of the research was to determine the possibility of producing dry-formed fibreboards with the use of various proportions of plant glue as a binding agent. The scope of work included the production of boards in laboratory conditions with 0%, 10%, 12%, 14%, and 20% mass fractions of plant glue and subjecting them to selected physical and mechanical tests. The results show, that the properties of the produced panels are strongly connected to the content of the plant binder (resination), and, by the proper tuning of resination, it is possible to produce dry-formed fibreboards (MDF type) with the use of plant glue that meets the requirements of proper standards.

The PLA content influence selected properties of wood-based composites. The aim of the research was to find how the lower (25%) and higher (50%) PLA content affects the selected properties of the obtained WPC samples. The result of the strength tests (compressive strength) shows, that the increasing content of PLA, increases the compressive strength value. The ash content value determining mineral saturation, decreasing with increasing PLA content but there is no significant difference. The moisture content was carried for wood sampleby drying the material and was figured by differences in the material weight mass. Raw material samples was compacted inside the chamber to form the composites by using high temperature (230°C) and strength not higher than 600 N. Optical analyzed was performed for analyzing the structure of the prepared sample, and comparing that structure before and after strength test. It can be concluded, that increasing thermoplastic content in biocomposites causes better strength, and it has not significant bad impact on the environment.

Investigating cotton dyeing using exotic wood sawdust. The study investigated the possibility of using extracts from various species of exotic wood, obtained from waste sawdust, for dyeing cotton fabrics. Material from Obeche, Iroko, Merbau, Apple tree, American walnut, Tulip tree, Cumaru and Rosewood were used for the tests. Solutions of oxalic acid, tin chloride, aluminum sulfate and ferric chloride were used as mordants, along with no-mordant tests. The color was determined in the CIE L*a*b* coordinate system. Color fastness was tested using n-hexane for dry cleaning and acidic, alkaline and hydrogen peroxide bleach solutions. The results showed a strong dependence on the type of wood, the mortar used and the washing agent and covered a wide spectrum of color intensity and fastness. The best results were obtained for Rosewood, Merbau and Apple trees, while Tulip tree and American walnut turned out to be practically useless. Among the mordants used, the most intense colors were produced by metal salts, including ferric chloride, which strongly darkened fabrics. Dry cleaning proved to be the mildest of those tested, with the least effect on color fading.
