	Structural Features
	Your choices are...
	Thermal Bond		Many fabrics can be strengthened by the addition of heat to fuse adjacent fibers.  Often, pressure is applied to enhance the bond strength.
	Microfiber		Microfibers are extremely fine synthetic or natural fibers that can be incorporated into textiles to provide the texture and drape of natural-fiber cloth, but with enhanced washability, breathability, and water repellency. Fine fibers produce structures with much smaller pore sizes for superior filtration.
	Blend		Yarn, cloth or textile products are manufactured from a mixture of two or more different type of fibers.
	Copolymer / Bicomponent		Copolymers are a combination of two or more polymers at the fiber level. They are produced via a co-polymerization process, or by co-spinning two different polymer melts.
	Chemical Bond/Binder Addition		Fabrics and textiles are made from chopped fiber and strengthened with the addition of a chemical binder (acrylic, polyvinyl alcohol, etc.), or by subjecting the material to a chemical (acid or solvent).
	Hydroentanglement		Fabrics can be strengthened and/or softened by impinging the material with a high velocity water jet.
	Chemical / Fuel Resistant		Materials are designed to resist damage caused by acids, alkalis, general chemicals, fuel and oils. These materials are used to seal fuel or oil tanks.
	Coated / Sized		Products are coated, filled or sized fibers, strands, mats, cloth or fabric.
	Electrically Conductive		Textiles or fabrics include fibers with high electrical conductivity or low electrical resistivity. Often, conductive filler is added to increase conductivity. Products are used in electronic, anti-static or electrostatic discharge (ESD) applications.
	Electrical Insulation / Dielectric		Dielectric fibers, fabrics and textiles are electrically insulating. Dielectric materials are used to form a barrier or isolator between electrical or electronic components.
	Flame Retardant		Products reduce the spread of flames or resist ignition when exposed to high temperature, or insulate the substrate and delay damage.  A UL 94 rating indicates that the material is flame retardant in accordance with Underwriters Laboratories, Inc. (UL) Flame Class 94V-0 or other equivalent ISO standards.
	Hydrophilic / Absorbent		The surfaces of hydrophilic materials can be wet by water. They are often used when high absorbency (many times the basis weight of the material) is important.
	Sound Proofing / Insulation		Sound proofing or acoustic insulation materials are used to form a barrier or isolator between components and sources of noise or vibration. This category includes foam material products used for diffusing sound without causing a large degree of attenuation.
	Thermal Insulation / Fireproofing		Thermal insulation materials provide a barrier between a component and a heat source.
	UL Approved / Listed		Materials meet applicable standards from Underwriters Laboratories, Inc. (UL).
	Hydrophobic/Waterproof		Waterproof materials do not dissolve or degrade when exposed to water. The fabric may still absorb water if the product is hydrophilic and has open porosity.
	Weather / UV Resistant		Plastic or elastomer foams are resistant to ultraviolet (UV) light or sunlight. Some non-UV resistant foam will crack, yellow or degrade on exposure to UV light. Weather resistant materials can withstand exposure to the elements, such as wind, rain, snow dust, humidity, heat, cold and other weather conditions.
