Durability: mohair can be twisted or bent without damaging the fiber. This is due to its structure, supporting the claim that it is the most durable of all animal fibers. Elasticity: mohair will stretch an average 30% over its length and then will be able to spring back into shape.
Mohair is a fabric or yarn made from the hair of the angora goat both durable and resilient, mohair is notable for its high luster and sheen, and is often used in fiber blends to add these qualities to a textile.
This paper investigates the physical properties of poly(p-phenylene-co-3,4'-oxy diphenylene terephthalamide) [pppot] fibers in comparison with poly (p-phenylene terephthalamide ) (ppta) fibers.
Some of the other the melting point of greases made with various soaps will differ appreciably.
Grease mohair also called raw mohair this means the mohair still has the natural grease and dirt that was on the hair when it was shorn from the goat. Angora goats are only shorn 1-2 times per year, so the hair sold as grease will have at least 6 months worth of lanolin and dirt.
General information physical properties application chemsol acrylic primer is a zero voc water based one component acrylic primer that is designed to increase the adhesion of chemsol 75 anti-skid floor coating. It is designed for use on porous surfaces including asphalt, wood and concrete.
Epidermis or cuticle (bounces back), it gives unique properties: rapid wrinkle recovery durability bulk warmth mohair - most.
Mohair fiber is not as thin as cashmere and alpaca (mohair fiber is 25-45 microns in this book covers all aspects of the growth, physical characteristics,.
Mohair is similar to wool, although it does possess other unique properties not found in any other type of fiber. Luster: the luster of mohair is one of the most important characteristics. Luster is the natural sheen of the fiber caused by light being reflected more directly by the larger outer scales of the fiber.
Mohair is composed mostly of keratin, a protein found in the hair, wool, horns and skin of all mammals, but mohair's special properties are unique to the angora goat. While it has scales like wool, the scales are not fully developed, merely indicated. Thus, mohair does not feel the same way common or standard wool does.
Due to their high base oil viscosity, these greases form a comparatively thick, elastohydro- dynamic lubricant film that gives damping of shocks.
Dec 24, 1971 mohair, by virtue of its open fleece structure, is more generally exposed to weathering than wool and its grease is therefore more oxidised than.
Adult females stand 36 inches tall and weigh between 70–110 pounds; males stand 48 inches tall and weigh 180–225 pounds. Their main defining characteristic is long (8–10 inches at shearing) ringlets of hair which are fine, silky, lustrous, and dazzlingly white in color and contain little oil in the fleece.

This type of grease and paste are waterproof and offers great fluidity and performances over a wide temperature range.
When machine looms were invented, velvet production became much less expensive, and the development of synthetic fabrics that somewhat approximate the properties of silk finally brought the wonders of velvet to even the lowest rungs of society.
Wastes from the wool and mohair scouring industry are oil-in-water emulsions in which the oily phase consists of relatively fine droplets of wool grease. They contain, in addition to wool grease, dissolved salts (mainly suint), suspended solids and bacteria and are stabilised mainly by a detergent and a suitable builder.
Physical properties were determined on specimens prepared under laboratory conditions using applicable astm procedures. Actual field conditions may vary and yield different results; therefore, data are subject to reasonable deviation. 202sl is a self-leveling coating sys-tem for flooring applications.

Nov 28, 2015 all you need to know about mohair suiting fabric, the perfect cloth for tuxedos, there are many reasons to appreciate the remarkable characteristics of mohair: this process involves physical inspection and estimat.
Cellulose fiber response to mechanical stresses change depending on fiber type and chemical structure present. Information about main mechanical properties are shown in the chart below and can be compared to properties of commonly used fibers such glass fiber, aramid fiber, and carbon fiber.
Physical properties natural crimp scales allow for felting variable luster – tends to be low properties of wool mechanical: moderate abrasion resistance, low tenacity (especially when wet), good flexibility, high elongation. Poor dimensional stability, good resiliency when dry, medium density, high thermal retention properties.
The wool is sheared or clipped from the animals during springtime (once a year). It may be stiff and sticky due to lanolin/wool grease at this point. Sheep can be categorized according to the kind of fleece they give.
There are a variety of ways to remove the greasy lanolin in raw wool, but most large wool producers use chemical catalysts for this process.
The wool grease and dried perspiration combined are referred to as “yolk. Character refers to general appearance and crimp, color, and condition of the fleece.
These differences in physical structure of the surface of rare animal fibers, compared with wool, will be at least partially responsible for the greater difficulty in processing mohair and cashmere, and will also contribute to desirable aesthetic advantages such as softness and lustre and different friction properties.
This paper examines the effects of naphthenic, paraffinic, and synthetic (polyalphaolefin or pao).
Mohair fibre is long, lustrous, strong, resilient, and durable. It absorbs and retains moisture much like wool and has good affinity for dyestuffs but is more sensitive to chemicals. It reacts much like wool when subjected to heat, sunlight, moth larvae, and aging. Because of its scale structure, mohair felts less readily than wool.
Functional properties of grease grease functions as a sealant to minimize leakage and to keep out contaminants. Because of its consistency, grease acts as a sealant to prevent lubricant leakage and also to prevent entrance of corrosive contaminants and foreign materials.
Fibre diameter is commercially one of the most important properties of mohair. This is mainly because it determines spinning performance, yam and fabric properties and the end-use potential of the fibre. It is therefore important that mohair fibre diameter be measu~d accurately on a routine basis.
