A moisture meter gives a reading of the approximate moisture content of wood. The reading helps in determining whether the wood is suitably dry for its intended purpose. The moisture content reading can also assist in planning a project design that will accommodate future changes in dimension caused by changes in relative humidity.
One form of pictograph found in ancient and traditional rock paintings is created by the hand first being placed against the panel, with dry paint then being blown onto it through a tube, in a process that is akin to air-brush or spray-painting. The resulting image is a negative print of the hand, and is sometimes described as a "stencil" in ...
Moisture management or moisture-wicking is a functional property in textiles that enables them to transfer moisture from the skin, by capillary action through the fabric, spreading it over a large external surface area, which helps in drying quickly. [1] [2] The property is one of the most important for thermal comfort of textiles. [3]
Coatings were prepared by moisture curing of IPDI capped hydroxyl terminated polybutadiene/clay dispersions in a relative humidity (RH) of 50% at 25 °C. Moisture cured polyurethane–urea coatings have been made by reacting 1,2,3-triazole rich polyether polyols with HMDI at NCO/OH eq. ratio of 1.2 to obtain isocyanate-terminated polyurethane ...
[26] [27] Wool scouring is the next process after the woollen fleece of a sheep is cut off. [28] Raw wool is also known as ''Greasy wool.'' "Grease" or "yolk'' is a combined form of dried sweat, oil and fatty matter. [29] Lanolin is the major component (5-25%) of raw wool which is a waxy substance secreted by the sebaceous glands of wool ...
The purpose of the inner layer is to draw sweat away from the skin to the outer layers to make them feel warmer. If a piece of clothing does not transfer moisture well, it is not strictly an inner layer garment but simply a mid-layer garment. Wool has a combination of wicking and water-repelling properties [1] and is highly odour-resistant. [2]
In the Power-Heat-Set process yarn is heat set with superheated steam in an open system at atmospheric pressure. All the materials normally used in the carpet industry such as polyamide 6, polyamide 6.6, polypropylene, Acrylic, PET, polyester and wool can be processed. The unprocessed yarn is provided on packages in a creel (up to 72 packages).
Moisture sorption isotherm. The relationship between water content and equilibrium relative humidity of a material can be displayed graphically by a curve, the so-called moisture sorption isotherm. For each humidity value, a sorption isotherm indicates the corresponding water content value at a given temperature. If the composition or quality ...
