Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
Superabsorbent polymer: Polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass. [5] Notes: The liquid absorbed can be water or an organic liquid. The swelling ratio of a superabsorbent polymer can reach the order of 1000:1. Superabsorbent polymers for water are frequently polyelectrolytes.
Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. [1] Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation), filtration, soundproofing, and hydroponic growth medium.
The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m 3 (1.1 g/cm 3), while typical expanded perlite has a bulk density of about 30–150 kg/m 3 (0.03–0.150 g/cm 3). [2]
Natural fibers are also used in composite materials, much like synthetic or glass fibers. These composites, called biocomposites, are a natural fiber in a matrix of synthetic polymers. [1] One of the first biofiber-reinforced plastics in use was a cellulose fiber in phenolics in 1908. [1]
Another mineral resembling the emerald is green jasper (taking into account the implication of Bareketh that it was green); there is much to be said for bareḳet being this stone. [24] Although "emerald" is the most common form used to describe the Hebrew word, bareḳet , in other sources (e.g. the Septuagint on Ezekiel 28:13), the word ...
Alcantara is composed of about 68% polyester and 32% polyurethane, [6] giving increased durability and stain resistance. The appearance and tactile feel of the material is similar to that of suede, and it may be erroneously identified as such.
The "face" is a weaver's term that refers to whether the warp or weft dominates the fabric. [5] The three-dimensional face/texture of waffle make it more absorbent and a useful fabric. Waffle fabric is usually made of cotton or microfibre and is woven in a way that makes it very absorbent. The waffle weave also allows air to flow through the ...
