Carpet

== Description ==
A thick heavy floor covering. Carpets are made from wool, silk, or synthetic fibers. Famous carpet making centers include Turkey, Iran, Afghanistan, India and China. Major European factories were founded in Brussels and Kidderminster. Early rugs were flat-woven; by the 14th century, hand-knotted pile rugs with a backing system were introduced in Asia. The types of knots used are characteristic of their region of production. Looms for weaving carpet were first patented in England in 1749 and by the early 19th century, machine-tufted rugs were commercially available. Until the 1960's most rugs were made from wool, but by 1980, most machine-made carpets were composed of synthetic fibers, such as nylon (Antron®), polypropylene (olefin), polyester, acrylic (Orlon®), and saran. As of 1999, most carpets are made from nylon; it offers wear resistance and resiliency but must be treated to improve stain resistance and decrease static charge. Polyester is soft and easily cleaned but does not wear as well as nylon. Acrylic feels like wool and has low static electricity. Olefin is strong and durable; it is used in indoor outdoor carpets.
== Synonyms and Related Terms ==
rugs; tapete (Esp., Port.); alfombra (Esp.); tapis (Fr.); vloerkleed (Ned);

Carpet backing

== Description ==
A stiff, coarse, open-weave fabric used to supported the weave or tufting of a carpet. Early carpet backings were made from cordage type fibers such as jute, hemp, or sisal. Some carpet backings were coated with rubber or latex after weaving. Modern machine made carpets are woven onto synthetic backing fabrics, such as nylon and polypropylene.

Carpet beetle

== Description ==
Any of several small insects of the hide beetle genera Anthrenus, Attagenus and Anthrenocerus. The larvae of the carpet beetles feed on proteinaceous materials, such as wool, silk, fur, hair, horn, skin, leather, and feathers. The adult carpet beetle is about 4 mm long with black, red and white marking on its back and a white stomach. It deposits eggs in cracks in the floor under the carpet then the developing larvae feed on the carpet. Carpet beetle have a long life cycle. The adults can eat pollen, plants materials, fabrics, fur and feathers. The eggs and larvae can become dormant in cool or dry conditions and resume their growth when the environment improves.

Carrageenan

== Description ==
A water-soluble polysaccharide extracted from several species of red edible seaweeds such as Chondrus crispus. Carrageenan forms thermo-reversible gels that can change from gel to liquid with changing temperatures. It is used as an emulsifier and stabilizer in food products. Traditionally, marbled papers and fabrics were prepared by laying them on top of colors floating on the surface of a carrageenan mixture. The gels have also used as an adhesive in mounting Chinese paintings.
There are three main commercial classes of carrageenan:
* Kappa forms strong, rigid gels in the presence of potassium ions, and reacts with dairy proteins. It is sourced mainly from Kappaphycus alvarezii
* Iota forms soft gels in the presence of calcium ions. It is produced mainly from Eucheuma denticulatum
* Lambda does not gel, and is used to thicken dairy products

Carthamin

== Description ==
Dark red powder with green luster. Carthamin one of two colorants extracted from safflower (Carthamus tinctorius). The flowers of the safflower plant contain a yellow dye and a red dye. The yellow colorant, safflor, is water soluble. The red dye, carthamin, is extracted from the crushed flower heads with a weak alkali solution after the yellow has been removed with cold water. Both colors dye vegetable fibers better than animals fibers although safflower was used for dyeing red and pink silk. It was also used to dye government red tape and may have been used as a pigment. Carthamin is not a permanent color and is sensitive to acids, alkalis, and light.
