Thinsulate fibers are about 15 micrometres (0.00059 in) in diameter, [8] which is thinner than the polyester fibers normally used in insulation for clothing such as gloves or winter jackets. Advertising material suggests that Thinsulate is more effective due to the increased density of fibers with decreased size of fibers compared with more ...
Down rated 500–650 in 3 /oz (290–380 cm 3 /g) is warm enough and light enough for most conditions, and 800–900 in 3 /oz (460–520 cm 3 /g) fill is used for very lightweight and/or very cold-weather gear. Down is warm, lightweight and packable. If well cared for, it retains its loft up to three times longer than do most synthetics. [38]

Polar fleece garments are traditionally available in the micro, 100, 200, and 300 variants, where the numbers represent the fleece's weight in grams per square meter (gsm). The heavier fleece are warmer. Fleece can range from being high loft to tightly knit. High loft fleece is warmer because it traps tiny air pockets which holds body heat. [8]
One of the most interesting properties of Modacrylic fabrics is the arc flash protection, where it has very good values. Modacrylics are poor conductors of heat. The fabrics are soft, warm and resilient but are prone to pilling and matting. Modacrylics display high performance when it comes to appearance retention.
The yarn is 100% polyester or a blend of 45% polyester fibers and 55% merino wool, and is used in socks, sweaters, base layers, and accessories intended mainly for outdoor wear. [ 3 ] In 2010, PrimaLoft was the first maker of branded insulation to be recognized for compliance with the bluesign criteria for environmental effect. [ 4 ]
It is inherently more stable than both cellulose nitrate and cellulose acetate, because it is a synthetic polymer that is inert (chemically inactive). It shows exceptional chemical stability and physical performance. [1] A polarization test can be used to identify polyester from cellulose acetate or nitrate. When viewed between cross-polarized ...
Polylactic acid (polylactide) is a compostable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), sugar beet pulp (in Europe), tapioca roots, chips or starch (mostly in Asia), or sugarcane. It is the most common material used for 3D printing with fused deposition modeling (FDM ...
