(b). ... Orlon; 67.9% C, 5.70% H, 26.4% N. A major textile dye manufacturer developed a new yellow dye. Generally has very good resistance to mineral acids; excellent resistance to common solvents, oils, greases, neutral salts, sunlight; fairly good resistance to weak alkalies but is degraded by strong alkalies. Formula. Given the chemical formula of the substance, we were able to determine the amount of the substance (moles) from its mass, and vice versa. It has a role as a polar aprotic solvent and a hepatotoxic agent. Flammability similar to that of rayon and cotton. ...

Acrylonitrile | H2CCHCN or H2C(CH)CN or CH2=CH-CN or C3H3N | CID 7855 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Dyes are classified based on both the structure of the dye and the way in which the dye is applied to the fabric. Which one of the following is the chemical formula for the repeating unit in polyethylene: (a) CH2, (b) C2H4, (c) C3H6, (d) C5H8, or (e) C8H8? It is a volatile organic compound and a member of formamides. But what if the chemical formula of a substance is unknown? Sp gr 1.17. Example 2. N,N-dimethylformamide is a member of the class of formamides that is formamide in which the amino hydrogens are replaced by methyl groups. Petroleum products are used to produce synthetic fibers such as nylon, orlon, and dacron, and other polymers such as polystyrene, polyethylene and synthetic rubber. Answer. Unit - Chemistry of Garments: Synthetic (man-made) Fibres Acrylic, Aramid ( Twaron, Kevlar, Technora, Nomex), Microfiber, Modacrylic, Nylon, Olefin Polyester, Polyethylene ( Dyneema, Spectra), Spandex, Vinylon, Vinyon, Zylon Nylon (Polyamide) Nylon is a thermoplastic silky material, first commercially used in a nylon-bristled toothbrush (1938). This colorless liquid has a characteristic acrid or tart smell. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. What is the molecular or formula mass of the following: C₁₂H₂₂O₁₁ (sucrose, cane sugar) ... Orlon; 67.9% C, 5.70% H, 26.4% N. C₃H₃N. Ironing temps above 160° may cause yellowing. As long as we know the chemical formula of the substance in question, we can easily derive percent composition from the formula mass or molar mass. This is a plastic that has the following chemical formula: CH2=CHCl (see picture on the right). La resistencia de las acrílicas a los tintes y el alto costo de producción limitó su uso en estos usos finales. Plastic covers a wide rage of synthetic or semi-synthetic polymerization products (i.e. What is the molecular or formula mass of the following: CH₃CO₂H (acetic acid) 60.06 amu. Sticks at 235°. Más tarde se alcanzó éxito utilizando fibras cortas de menor resistencia. Degree of polymerization is which one of the following: (a) average number of mers in the molecule Acrylic acid (IUPAC: propenoic acid) is an organic compound with the formula CH 2 =CHCOOH. Polyester (Dacron) Acrylic (Orlon) C Nylon-6,6 O O CH2 CH2 H n H H n H n Wool (Protein) Figure 1. Properties. long-chain carbon-based "organic" molecules) which name refers to the fact that in their semi-liquid state they are malleable, or have the property of plasticity. Chemical Structures of Fabric Molecules. The most common and thermodynamically favored chemical transformations of alkenes are addition reactions. It is miscible with water, alcohols, ethers, and chloroform.More than a million tons are produced annually.
