“…Cotton exhibited the most unique structure due to its convoluted fibril arrangement, with comparatively larger pores. [31] All materials exhibited low fluorescence across the visible light spectrum, substantiating further characterization given their potential applicability to fluorescent systems (Figure 2g).…”

“…This effect can be expected to be amplified with the saturation of the cotton membrane, as wet cotton fibers offer a larger physical footprint and higher mechanical strength. [ 31 ] To visualize anti‐diffusive effects toward macroscale entities, buffer‐saturated cotton membranes were visualized via SEM after chicken purge processing (Figure S8b, Supporting Information). These images indicated lipid deposition onto the cotton fibers at a macroscale, while retaining sufficient porosity to permit analyte and buffer diffusion at the microscale, further substantiating the use of this membrane within the proposed platform.…”

With food production shifting away from traditional farm‐to‐table approaches to efficient multistep supply chains, the incidence of food contamination has increased. Consequently, pathogen testing via inefficient culture‐based methods has increased, despite its lack of real‐time capabilities and need for centralized facilities. While in situ pathogen detection would address these limitations and enable individual product monitoring, accurate detection within unprocessed, packaged food products without user manipulation has proven elusive. Herein, “Lab‐in‐a‐Package” is presented, a platform capable of sampling, concentrating, and detecting target pathogens within closed food packaging, without intervention. This system consists of a newly designed packaging tray and reagent‐infused membrane that can be paired universally with diverse pathogen sensors. The inclined food packaging tray maximizes fluid localization onto the sensing interface, while the membrane acts as a reagent‐immobilizing matrix and an antifouling barrier for the sensor. The platform is substantiated using a newly discovered Salmonella‐responsive nucleic acid probe, which enables hands‐free detection of 103 colony forming units (CFU) g−1 target pathogen in a packaged whole chicken. The platform remains effective when contamination is introduced with toolsand surfaces, ensuring widespread efficacy. Its real‐world use for in situ detection is simulated using a handheld fluorescence scanner with smartphone connectivity.

“…21 Similarly, different cultivars of cotton and flax revealed variations in productivity and physical properties. 22,23 Four major cultivars of cotton of commercial importance are grown around the world: Gossypium hirsutum ( G. hirsutum ) (commonly known as “American Upland” or “Long-Staple/LS” cotton) with fiber length of 0.875 to 0.938 inches; G. barbadense (commonly known as “American Pima” or “Extra Long Staple/ELS” cotton) with fiber length of 1.25 to 1.188 inches; and G. herbaceum and G. arboretum with comparatively shorter fiber length of 0.5 to 1.0 inch. 24 Furthermore, fibers obtained from the same bolls of any cotton plant may differ in length, diameter, and also fiber strength.…”

“…24 Furthermore, fibers obtained from the same bolls of any cotton plant may differ in length, diameter, and also fiber strength. 22 Cottons with longer fiber length and finer diameter are considered higher quality. After conducting research on ten different cultivars of flax, it was concluded that productivity is dependent on the cultivar – cultivar Ariane showed very good productivity, whereas cultivar Nynke showed medium productivity.…”

Due to the excessive use of water required for cotton cultivation, scientists in this field have been looking at waste biomass as an alternative source of fiber supply. Canola waste biomass is a source of textile fibers which effectively costs nothing, as the biomass can be collected from the waste plant stems of canola plants after harvesting. Therefore, an investigation has been conducted to identify the characteristics of canola fiber and of the canola cultivar ( Brassica napus L.) suitable for textile applications. In this research, a bio-inspired approach was applied to produce fiber from canola biomass by water retting of four different cultivars (HYHEAR 1, Topas, 5440, and 45H29) cultivated in a greenhouse under controlled atmospheric conditions. It was found that the structural hierarchy of fiber density, mechanical properties and other textile fiber properties of canola fiber differ from cultivar to cultivar, which can be carefully harnessed for different applications. Further, it was found that the density of canola fiber is much lower than that of cotton and other competitive bast fibers, owing to its hollow structure, as revealed by scanning electron microscopy. The results suggest that canola may be an excellent choice for manufacturing of non-woven fabrics, eco-composites, apparel or other technical textiles.

“…Faktor-faktor lain yang dapat mempengaruhinya adalah usia serat, jenis anyaman kain, diameter dan arah puntiran benang penyusun kain, kondisi kain sebelum diuji, serta metode uji. 29,30 Binder dapat membentuk lapisan di permukaan kain dengan bantuan udara panas ketika curing. Lapisan tersebut menahan mikrokapsul tetap berada pada permukaan kain, permukaan kain menjadi lebih tebal sehingga kekuatan tariknya meningkat.…”

Salah satu proses untuk meningkatkan fungsi kain kapas adalah penyempurnaan dengan mikrokapsul. Mikrokapsul tersebut diharapkan memiliki ketahanan yang memadai pada permukaan kain kapas. Namun karena penyalut mikrokapsul tidak berikatan kimia dengan kain kapas maka digunakan zat pengikat (binder) seperti poliakrilat dan poliuretan. Penelitian ini bertujuan untuk mempelajari efektivitas binder berbasis poliakritat dan poliuretan pada penyempurnaan mikrokapsul kain kapas menggunakan teknik padding. Kain kapas hasil penyempurnaan mikrokapsul diamati permukaannya dengan Scanning Electron Microscope (SEM), diuji ketahanan cucinya dengan Launder-O-meter, kekuatan tariknya dengan tensile tester, dan kekakuannya dengan stiffness tester. Mikrokapsul selanjutnya dianalisis ukuran partikel menggunakan Particle Size Analizer (PSA) dan jenis penyalutnya menggunakan Fourier Transform Infra Red (FTIR). Hasil penelitian menunjukan bahwa ukuran ratarata mikrokapsul adalah 1,14 µm, binder poliakrilat dan poliuretan dapat mempertahankan mikrokapsul dipermukaan kain kapas hingga setara 10 kali pencucian rumah tangga. Penggunaan binder poliakrilat 12,5 % dapat meningkatkan kekuatan tarik kain kapas 12,47 % arah lusi dan 2,41 % arah pakan, serta kekakuannya 7,31 %, sedangkan binder poliuretan 10 % dapat meningkatkan kekuatan tarik kain kapas 17,87 % arah lusi dan 3,32 % arah pakan, serta kekakuannya 25,69 %.
