The surface of untreated wool has been investigated using x-ray photoelectron spec troscopy (XPS) and static secondary ion mass spectrometry (SSIMS). is covered in a thin layer lipid estimated to be approximately 0.9 nm thick. Mass spectral peaks are consistent with the presence saturated C 20 , 21 hydroxylated fatty acids, presumably bound as esters. This can partially, but not completely, removed by treatment potassium tert-butoxide tert-butanol or hydroxide, reagents that cause oxidation...
This study examines the effects of an atmospheric pressure plasma (APP) pre‐treatment on shrink resistance wool fabric treated subsequently, by pad/dry method, with aqueous emulsion amino‐functional polydimethylsiloxane, SM 8709. Optimal (with no impairment handle) was obtained after a low‐level treatment (1–3 s exposure time), using 5% polymer emulsion. Higher levels silicone could be used to achieve in absence pre‐treatment, but handle would adversely affected. X‐ray photoelectron...
Atmospheric pressure plasma treatment of wool fabric, with a relatively short exposure time, effectively removed the covalently bonded lipid layer from surface. The plasma‐treated fabric showed increased wettability and fibres greater roughness. X‐ray photoelectron spectroscopy (XPS) analysis much more hydrophilic surface significant increases in oxygen nitrogen concentrations decrease carbon concentration. Adhesion, as measured by scanning probe microscopy (SPM) force volume analysis, also...
Abstract This project was aimed at delivering a cost-effective, manufacturable and well characterised vest for impact detection, to support hdevelopment of an automated scoring system amateur boxing. The initial work focused on partial automation the manufacture existing boxing design increase vest’s robustness allow small scale manufacture. multiplication sensor enabled routine use in field trials that assisted development related hardware software but involved wide combination time...
As part of a program directed at zero-AOX shrinkproofing treatments, we have compared the reactivity different oxidants with wool by following their disappearance under similar conditions. The series was as follows: aqueous chlorine > DCCA ~ permonosulfate permanganate / salt peracetic acid persulfate hydrogen peroxide. This not related to redox potentials but generally followed level shrink resistance imparted oxidant. Fourier transform infrared spectroscopy using attenuated total...
In this study, the effect of pre-plasma treatment on adsorption silicone to enhance heat transfer resistance basalt fabric for protective clothing was investigated. Fabrics were treated with plasma prior surface coating. Changes un-sized fibre characterized by using scanning electron microscopy (SEM), probe (SPM), X-ray photoelectron spectroscopy (XPS), and contact angle measurement. Furthermore, (SEM) coated assessed. The results show that different percentage add-ons had a significant rate...
There is limited information available on variation among individual fleeces in yarn and fabric performance. In this study, 45 mid-side fleece samples (~30 g clean wool) with a wide range fibre diameter, diameter variation, curvature felt ball were used to determine whether these characteristics significantly affected shrinkage, pilling. Mid-side wool ranged from 13.5 24.0 µm mean 46–108°/mm 22.2–30.2 mm diameter. Yarn shrinkage was (P < 0.001) correlated (r = –0.52), total 0.99). Fabric...
The oxidation of soot behind reflected shock waves has been studied over the temperature range 1600–3000 K at oxygen concentrations 1% to 40% and total pressures 6 atm. Two colour pyrometry was used monitor surface laser absorption particle rates. combustion regions were observed. At low temperatures below 2100 K, rate increased with give an activation energy 110±20 kJ mol−1 dependence 0.5. higher a regime found where became constant increasing temperature. latter concentration.
