The secondary cell wall development of cotton fibers harvested at 18, 20, 24, 28, 32, 36 and 40 days after flowering was examined using attenuated total reflection Fourier transform-infrared (ATR FT-IR) spectroscopy. Spectra deuterated did not demonstrate significant changes in their O–H stretching band shapes or positions during development. Only a progressive increase intensity observed. Results indicate that the highly crystalline cellulose component produced formation maintains hydrogen...
The need for affordable effective prehospital hemostatic dressings to control hemorrhage has led an increased interest in new dressing design approaches. Here we consider the separate components of fabric, fiber, and procoagulant nonexothermic zeolite-based formulations on approaches accelerated hemostasis. fabric was based incorporation zeolite Y as principal procoagulant, with calcium pectin adhere enhance activity. Unbleached nonwoven cotton when combined bleached displays enhanced...
In this paper, we studied the synthesis, characterization, and flammability of water-soluble, nonhalogenated organophosphorus flame retardant (FR) dimethyl-[1,3,5-(3,5-triacryloylhexahydro)triazinyl]-3-oxopropylphosphonate for application to cotton fabrics by nonpolymeric network. The FR was synthesized in a one-step reaction from dimethyl phosphite 1,3,5-triacryloylhexahydro-1,3,5-triazine under mild conditions, its structure fully characterized 1H, 13C, 31P nuclear magnetic resonance...
The high demand for cotton production worldwide has demonstrated the need standardized classification of foreign matter present with cotton. Cotton trash can become comingled fiber during ginning and harvesting processes. conventional instrumental method used to determine amount fiber, volume instrument (HVI), lacks specificity in identification individual components (leaf, etc.). Fourier transform near-infrared (FT-NIR) spectroscopy was investigated distinguish types from fiber. In this...
Luminescent oligomers and polymers doped with silver(I) salts were used as optical sensors for ethylene other gaseous small molecules. Films of poly(vinylphenylketone) (PVPK) or 1,4-bis(methylstyryl)benzene (BMSB) impregnated AgBF4, AgSbF6, AgB(C6F5)4 respond to exposures a reversible emission quenching that is proportional the pressure gas. Experiments various analytes revealed only gases capable forming coordinate bonds Ag(I) ions (i.e., ethylene, propylene, ammonia) produced sensing...
Cotton gin waste presents a significant challenge in the cotton ginning industry due to its abundant generation and limited disposal options. In this study, we explored potential of as naturally occurring source material that can synthesize host silver nanoparticles. The noncellulosic constituents served effective reducing agents, facilitating conversion ions into atoms, while porous structure acted microreactor, enabling controlled particle growth. A simple heat treatment powder an aqueous...
A comparative study was conducted to identify the effects of processing on physical and combustion properties needlepunched (NP) hydroentangled (H-E) nonwoven fabrics produced from fibers white fiber cotton a naturally colored brown cotton. significantly higher degree flame retardancy (FR) in observed compared with fibers. Calorimetry revealed lower heat release capacity, peak rate, total The ash content also samples suggesting levels inorganic elements Elemental analyses had known FR...
Microfibers are small fiber particles that separate from larger textiles through wear abrasion or home laundering. Pervasive accumulation of synthetic microfibers in the environment is motivating efforts to quantify them, and gain a better understanding factors lead their release garments. Automated imaging systems have been previously employed for quantification natural microfibers. In current study, rayon standard sourced scoured cotton HVI calibration standards were examined with Fiber...
Greige cotton (unbleached cotton) is an intact plant fiber that retains much of the outer layers. These layers contain pectin, peroxidases, and trace metals are associated with hydrogen peroxide (H2O2) generation during development. When greige subjected to a nonwoven hydroentanglement process, components retained. hydrated, this fabric can generate H2O2 (5–50 micromolar). This range has been characterized as inducing accelerated wound healing enhanced cell signaling proliferation cells...
Greige cotton contains waxes and pectin on the outer surface of fiber that are removed when bleached, but these components present potential wound dressing functionality. Cotton nonwovens blended with hydrophobic hydrophilic fibers including viscose, polyester, polypropylene were assessed for clotting activity thromboelastography (TEG) thrombin production. Clotting was evaluated based TEG measurements: R (time to initiation clot formation), K from end a 20 mm clot), α (rate formation...
Market demands for cotton varieties with improved fiber properties also call the development of fast, reliable analytical methods monitoring and measuring their properties. Currently, breeders rely on instrumentation that can require significant amounts sample, which complicates studies. Herein, we explored use high-resolution, Fourier-transform infrared (FT-IR) microscopy to examine secondary cell wall in single fibers. Notably, there was a marked intensity increase C-O bending region near...
The development of affordable, effective, and environmentally friendly barrier fabrics is a current goal in antimicrobial textile development. discovery new routes to achieve non-toxic naturally occurring molecules with activity interest the materials that promote wound healing, improve hygiene, offer protection against nosocomial infection. Highly cleaned sterile unbleached cotton has constituents produce hydrogen peroxide at levels commensurate those favor cell signaling healing. Here, we...
A total of seven source fiber types were selected for use in the manufacturing nonwoven roll goods: polyester; polypropylene; rayon; greige cotton from two sources; mechanically cleaned cotton; and scoured bleached cotton. The microbial burden each was measured as a preliminary assessment contamination using heterotrophic spread plate counts. Greige fibers exhibited highest levels contamination, which reduced by both storage time trash removal form mechanical cleaning. Changes at step...
Infrared imaging is gaining attention as a technique used in the examination of cotton fibers. This type combines spectral analysis with spatial resolution to create visual images that examine sample composition and distribution.

In addition, measurements moisture content, stelometer flat bundle strength and elongation were collected at conditions. general trend observed for elongations measurements; in with higher RH generally resulted a progressive increase values. The broken fibers was also affected by Fibers high (i.e. 70 ± 2°F 80 2% RH) showed more frayed where...
ABSTRACT Introduction Developing affordable and effective hemostatic antimicrobial wound dressings for prolonged field care (PFC) of open wounds is interest to prevent infection, sepsis, conserve tissue viability. The need an dressing that also required a can be left in place extended periods (days). This particularly important light the existence pathogens have coagulopathy properties. Thus, provide hemostasis reduction frequency changes, whereas exerting robust activity are PFC. Highly...
Botanical and field cotton trash comingled with Upland lint can greatly reduce the marketability quality of cotton. Trash found during harvesting, ginning, processing is interest to textile community. In current study attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopic imaging was employed as an analytical technique analyze trash. Some benefits this were its non-destructive nature lack required sample preparation. The used in study, specifically ATR-FTIR chemical...
