Application Methods

There are three main application methods of phase change material incorporation: matrix infusion coating, in-fiber, and coating.

Matrix Infusion Coating

PCM Thermocules are finely printed onto flat fabric for next to skin products. Matrix infusion coating allows for an unchanged hand, drape, and wick.

In-Fiber

Acrylic, viscose, or polyester fibers are melt-spun with Thermocule PCM to achieve fiber embedded with PCM. This fiber is then spun into yarns then into fabrics or finished products. In-fiber is used for next to skin products.

Coating

Coated materials offer the highest loading capacity of PCM and thus the largest heat storage capacity of any application technique. Coated materials are not intended for next to skin products.

End-Uses

The majority of Outlast end-products fall in the categories of bedding, apparel, and footwear. The following table gives a non-exhaustive list of Outlast end-products.

Textile A vast field that includes fiber, yarn, fabrics, and various fiber-based products

Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns.

Composite material Material made from a combination of three or more unlike substances

A composite material is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions.

Carbon fibers Material fibers about 5–10 μm in diameter composed of carbon

Carbon fibers or carbon fibres are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high-temperature tolerance, and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, motorsports, and other competition sports. However, they are relatively expensive compared to similar fibers, such as glass fiber, basalt fibers, or plastic fibers.

Thermoplastic Plastic that becomes soft when heated and hard when cooled

A thermoplastic, or thermosoft plastic, is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.

Vectran Aromatic polyester fiber

Vectran is a manufactured fiber, spun from a liquid-crystal polymer (LCP) created by Celanese Corporation and now manufactured by Kuraray. Chemically it is an aromatic polyester produced by the polycondensation of 4-hydroxybenzoic acid and 6-hydroxynaphthalene-2-carboxylic acid.

Microfiber Synthetic fiber

Microfiber is synthetic fiber finer than one denier or decitex/thread, having a diameter of less than ten micrometers. A strand of silk is about one denier and about a fifth of the diameter of a human hair.

Tyvek

Tyvek is a brand of synthetic flashspun high-density polyethylene fibers. The name "Tyvek" is a registered trademark of the American multinational chemical company DuPont, which discovered and commercialized Tyvek in the late 1950s and early 1960s.

Metallic fiber Thread wholly or partly made from metal

Metallic fibers are manufactured fibers composed of metal, metallic alloys, plastic-coated metal, metal-coated plastic, or a core completely covered by metal.

Phase-change material Substance with high latent heat of melting or solidifying

A phase change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling. Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other. The phase transition may also be between non-classical states of matter, such as the conformity of crystals, where the material goes from conforming to one crystalline structure to conforming to another, which may be a higher or lower energy state.

Thinsulate

Thinsulate is a brand of synthetic fiber thermal insulation used in clothing. The word is a portmanteau of the words thin and insulate, trademarked by 3M. The material is made by the 3M Corporation and was first sold in 1979. It was originally marketed as an inexpensive alternative to down; at the time, 3M claimed it was twice as warm as an equivalent amount of any natural material.

Polyester Category of polymers, in which the monomers are joined together by ester links.

Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing.

Nonwoven fabric Sheet of fibers

Nonwoven fabric is a fabric-like material made from staple fibre (short) and long fibres, bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam.

Olefin fiber is a synthetic fiber made from a polyolefin, such as polypropylene or polyethylene. It is used in wallpaper, carpeting, ropes, and vehicle interiors.

A technical textile is a textile product manufactured for non-aesthetic purposes, where function is the primary criterion. Technical textiles include textiles for automotive applications, medical textiles, geotextiles, agrotextiles, and protective clothing.

PrimaLoft

PrimaLoft® is a brand of patented synthetic microfiber thermal insulation material that was developed for the United States Army in the 1980s. PrimaLoft is a registered trademark of PrimaLoft, Inc., the brand's parent company.

Finishing (textiles) Manufacturing process

In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing. The precise meaning depends on context.

Ceramic matrix composite Composite material consisting of ceramic fibers in a ceramic matrix

In materials science, ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix. The fibers and the matrix both can consist of any ceramic material, whereby carbon and carbon fibers can also be regarded as a ceramic material.

Aircraft fabric covering Material and method used to cover open aircraft structures

Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are the pioneering all-wood monocoque fuselages of certain World War I German aircraft like the LFG Roland C.II in its wrapped Wickelrumpf plywood strip and fabric covering.

Textile performance Fitness for purpose of textiles

Textile performance, also known as fitness for purpose, is a textile's capacity to withstand various conditions, environments, and hazards, qualifying it for particular uses. The performance of textile products influences their appearance, comfort, durability, and protection. Different textile applications require a different set of performance parameters. As a result, the specifications determine the level of performance of a textile product. Textile testing certifies the product's conformity to buying specification. It describes product manufactured for non-aesthetic purposes, where fitness for purpose is the primary criterion. Engineering of high performance fabrics presents a unique set of challenges.
