“…Netkani tekstilni materijali su visoko porozni materijali sa poroznošću koja je veća od 50% i obično iznosi oko 80% [4], što ove materijale čini veoma pogodnim za održavanje higijene u domaćinstvu [5]. Poželjno je da materijali za održavanje higijene u domaćinstvu, kao što su visokoapsorbujuće krpe, peškiri i sunđerasti artikli, pored dobrih sorpcionih svojstava (npr.…”

U radu su ispitivana prekidna svojstva dve grupe sunđerastih krpa dostupnih na tržištu Republike Srbije. Jednu grupu su činile sunđeraste krpe dobijene od mešavine viskoze i pamuka (uzorci 1-3), dok je druga grupa obuhvatala krpe ojačane poliestarskom mrežom (uzorci 4 i 5). Od prekidnih svojstava su određivani prekidna sila, prekidno izduženje, sila probijanja i hod kugle pri probijanju. Ispitivanja su realizovana na uzorcima neposredno nakon njihovog vađenja iz komercijalnog pakovanja (mokri uzorci), i sušenja na vazduhu (T=30 °C, φ=40%) u trajanju od dva dana (suvi uzorci). Dobijeni rezultati su pokazali da su ispitivana prekidna svojstva u funkciji sirovinskog sastava krpa i vlažnosti ispitivanih uzoraka, dok su prekidna sila i prekidno izduženje takođe i u funkciji pravca ispitivanja (uzdužni ili poprečni). Rezultati ocene kvaliteta ispitivanih krpa, dobijeni na osnovu kompleksnog koefi cijenta kvaliteta, pokazali su da samo uzorak 3 poseduje dobar kvalitet, dok ostala četiri uzorka imaju odličan kvalitet kako u mokrom, tako i u suvom stanju. Ključne reči: sunđeraste krpe, kvalitet, prekidna sila, prekidno izduženje, sila probijanja, hod kugle pri probijanju.

“…Nonwoven fabric, formed by the physical bonding of numerous fibers, is widely used as an industrial textile in applications such as thermal protective material 1 and filtering materials, 2 owing to its excellent performance with such properties as durability, filterability and flexibility. 3 For nonwoven fabric, microfibers could be considered the smallest units.…”

In the microscopic imaging scenario where the object thickness exceeds the depth of field of the microscope, multi-focus image fusion (MFF) is an effective method to generate an all-in-focus image. However, for nonwoven fabric for which the captured image number is up to 100 or more, the existing methods often underperform in areas near the fiber edges, owing to image ghosting and noise accumulation caused by the platform moving. To address the above problem, this paper presents a method designed to fuse multi-layer micro-images based on the combination of spectral and spatial features of the images. Firstly, the spectral domain-based map is generated by decomposition and reconstruction of the high-frequency and low-frequency components of the images, aimed at obtaining the edge information. Simultaneously, the spatial domain-based fuse map is built through sharpness measurement, referring to visual perception. Finally, the two methods are combined via an optimized weight to obtain an all-in-focus fused image. Four groups of real-world data consisting of 100 multi-focus nonwoven images are utilized to verify the superiority of this method. The experimental results demonstrate that the proposed method can obtain satisfactory performance in terms of both human visual evaluation and objective evaluation compared with the image fusion framework based on the convolutional neural network, MFF, region-based image fusion algorithm and convolutional neural network state-of-the-art fusion methods.

Porous polyurethane (PPU) membranes have particular significance for various uses, for example, laminated textiles, cell seeding, biomaterials, tissue engineering, and so forth. In this research, the synthesis of segmented PUs was conducted using a two‐step polymerization method and additional highly PPU membranes were produced by the leaching technique, using highly water‐soluble silica particles. A crucial discovery during this work was reducing the particle leaching time. To make a porous structure, the particles were leached out from the PU matrix over 5 min through sonication. An investigation was conducted into the surface morphology of the PPU membrane using a scanning electron microscopy. The microporous average diameter was approximately 2 μm. Thermogravimetric analysis, differential scanning calorimetry, water vapor transmitting, and water droplet resisting ability were the tests conducted to explore the properties of the porous membrane. The effects of different silica particle percentage ratios were investigated. Additionally, a highly porous membrane was laminated with fabric to obtain a water drop resistant, water vapor transmittable, and mechanically strong textile. Such a highly porous promising PU membrane may have a use in tissue engineering and laminated textiles. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48566.
