Grey and white wool roving. A roving is a long and narrow bundle of fiber. Rovings are produced during the process of making spun yarn from wool fleece, raw cotton, or other fibres.
A synthetic adsorbable suture material. Braided synthetic adsorbable multifilament made of polyglycolic acid and coated with N-laurin and L-lysine, which render the thread extremely smooth, soft and knot safe. A synthetic adsorbable suture material. Monofilament synthetic absorbable suture, prepared from the polyester, poly (p-dioxanone ...
The polymer is formed by free-radical polymerization in aqueous suspension. The fiber is produced by dissolving the polymer in a solvent such as N,N-dimethylformamide (DMF) or aqueous sodium thiocyanate, metering it through a multi-hole spinneret and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a stream of heated ...
Galled threads on an NPT fitting. (Zoom in on threads for better view) An electron microscope image shows transferred sheet-material accumulated on a tool surface during sliding contact under controlled laboratory conditions. The outgrowth of material or localized, roughening and creation of protrusions on the tool surface is commonly referred ...
