synthetic blend with cotton. Fabrics are made up of fibers which have their own chemical structure, which determines their classification. Polymers make up the fibers (Ball-Deslich and Funkhouser). Since cotton is natural, it comes from a natural cellulose fiber with the polymer of glucose (Cotton). Polyester is synthetic which can be classified as saturated or u...
Synthetic and natural fibers are the most essential part in clothes manufacturing. They make up the clothing we wear everyday. Fibers are made up of polymers, which are an arrangement of large molecules that are then made up of groups of even smaller molecules that are linked together to form a large chain structure. The smaller molecules are called monomers, and when they join together larger molecules are produced, making macromolecules (Bailey). Synthetic fibers are made up of polymers giving
INTRODUCTION How fast do different fabrics evaporate moisture? There are many different types of fabrics that are used for clothing. Generally, fabrics are broken down into two separate groups, natural fabrics and synthetic fabrics. Natural fabrics are fabrics that come from plants or animals. Synthetic fabrics are fabrics that are made from man-made materials. Natural fabrics have been around for thousands of years. There were four great fibers in the fabric industry history. They were wool

molecules called monomers linked together. Some polymers, like cellulose, occur naturally. Polymers have extremely high molecular weights, and made-up of many of the tissues of organisms, and have various uses in industries. The process by which molecules are linked together to form polymers is called polymerization (The American Heritage Science Dictionary, 2005). Polymeric compound is a compound made of many smaller molecules such as cellulose, chitin, soy protein, casein and many more. Polymeric is
Our walls and ceilings tragically lack cellulose insulation, permitting the cool air that the A/C worked so hard to produce seep out. The existing windows grant the heat from outside to attack our classroom’s temperature. To top it all off, the entire school sucks energy from the power grid like a plant sucks up water. Eco-friendly changes are not only simple, but just might break the grip of fossil fuels on our schools. Enhancing our walls with cellulose insulation offers us an easy way to not
The negative chronotropic substance is when the substance slows down (decreases also, called a depressants) the heart rate and positive substance speed up (increase also, called stimulant) the rate of the heart. With the effects of the chronotropic substances, these substances can cause an increase in the force and the velocity of the myocardial systolic contraction this is a positive substance, with a negative substance, it can decrease the velocity through the atrioventricular node, also decreasing
Polysaccharides Polysaccharides are polymers composed of multiple subunits of monosaccharides (simple sugars). They are formed by condensation reaction, in the same way as disaccharides are formed, the difference stands in the larger number of monomer units which they are composed from . The number of monosacchardies composing the chain is variable, and there are two types of chains that can be formed: branched or unbranched. The chains may be folded, thus making them compact and therefore
Cellulases are o- glycosyl hydrolases (GHs) that hydrolyse β-1,4 glucosidic bonds in cellulose. Cellulase system is grouped into “glycoside hydrolases (GH) family” classified by different means, according to their substrate specifities, reaction, mechanisms or structural similarities. The cellulase complex is found to contain three basic components which may be present either as single polypeptide or can be grouped together into multienzyme complex known as cellulosome. Cellulase system is composed
approximately 5 billion gallons/ annum ethanol was produced using food grains and production of 8 billion gallons/ annum ethanol is expected in 2015 with the use of lignocellulosic biomass. Major constituents of biomass containing polymers of sugars are cellulose and hemicelluloses whereas lignin forms a protective covering against various in...
One of the materials commonly used in manufacturing shirts is cotton. Cotton is a natural fiber harvested from the cotton plant. The word ‘cotton’ refers to four species in the genus Gossypium (family Malvaceae), which are G.hirsutum L., G.barbadense L., G.arboreum L., and G.herbaceum L. (Tripathi & Warrier, 2011). The taxonomy of cotton is as follow: Name Cotton Kingdom Plantae Division Magnoliophyta Class Magnoliopsida Order Malvales Family Malvaceae Genus Gossypium Table: Taxonomy of cotton Although
Lignin Lignin is the substance that makes plants “woody.” The name lignin originates from the Latin noun “lignum” that means “wood.” Most plants, but not all contain lignin. Lignin found within lignified plants differ in distribution among the parts of the plant, as well as different species of plants (Harkin1969). Lignin is the generic term for a large group of polymers. These polymers accumulate within secondarily thickened walls, making them rigid and resistant. Lignin evolved when plants began
ingredients in a bouncy ball recipe affect a ball’s bounciness? Background Research: Molecules that are made of recurring chemical units are called polymers. The glue used in this experiment to create bouncy balls contains the polymer polyvinyl acetate (PVA). When this is reacted with Borax, the polymer cross-links to itself. Cornstarch, another major ingredient the bouncy balls, acts as a thickening agent. Hypothesis: If the amount of Borax in the solution is doubled, then the ball will bounce
nail polish is nitrocellulose. Nitrocellulose is a long lasting film forming agent. (Madnani 2012) It’s made from nitrated cellulose derived from plant cells. Cellulose is a naturally occurring component in the cell wall of green plant, most often cotton plants. Fibers of the cotton are ground so small that they don’t have to be removed from the product.(Winkler 2013) Cellulose is nitrated to form an ester, thus, nitrocellulose if formed. Nitrocellulose is one of the most useful film forming agents
Soft water and hard water are common terms used in households .Most of Earth's water (97%) is in the ocean. Seawater has unique properties: it is saline, its freezing point is Slightly lower than fresh water, its density is slightly higher, its electrical conductivity is much higher, and it is slightly basic. we cannot used brine water for domestic purpose. So it is needed to convert it into soft water. In this paper we observe the techniques of softening water. Seawater is water from a sea or ocean

1.2.2.1 Cuticle Due to protonic natureconsists of protein, it is smooth and water resistant and it is the outermost thin layer.Meanwhile there is a propensity to mistake primary wall with the cuticle, but these are particular and distinctive structures botanical view. During their life cycle, at some stage, cuticle are presented in the air, usually consider a characteristic of cells [10]. The structure of the cuticle has been determined that it is often extremely thin as comparatively few plants
The substantial improvement of mechanical properties of polymer nanocomposites can be attributed to high rigidity and aspect ratio of nanoclay combined with good affinity through interfacial interaction between polymer matrix and dispersed nanoclay. It is well reported that polymer nanocomposites have excellent barrier properties against O2, CO2 and water vapor. This depends on the type of clay, i.e., compatibility between clay and polymer matrix, structure of nanocomposites and aspect ratio of clay
