Cotton cloth

Rubber and Synthetic Elastomers. For many years nondecorative coated fabrics consisted of natural mbber on cotton cloth. Natural mbber is possibly the best all-purpose mbber but some characteristics, such as poor resistance to oxygen and ozone attack, reversion and poor weathering, and low oil and heat resistance, limit its use to special appHcation areas (see Elastomers, synthetic Rubber, natural). 

It is said that Alexander the Great introduced Indian cotton into Egypt in the fourth century BC, and from there it spread to Greece, Italy, and Spain. During the year AD 700, China began growing cotton as a decorative plant, and AD 798 saw its introduction into Japan. Early explorers in Pern found cotton cloth on exhumed mummies that dated to 200 BC. Cotton was found in North America by Columbus in 1492. About 300 years later, the first cotton mill was built in Beverly, Massachusetts, and in 1794 EH Whitney was granted a patent for the invention of the cotton gin. 

AH latex compounds should contain at least 5 phr of zinc oxide. This is needed to absorb evolved hydrochloric acid either in the compound or finished part. A larger amount should be considered if the part contains or is in contact with acid-sensitive materials such as cotton cloth. Magnesium oxide may destabilize anionic soap systems, and is avoided for that reason. The compound should also contain two parts of an antioxidant, and consideration should be given to the need for a uv screen in light-colored products. 

This includes organic fibrous materials on a cellulose base such as paper, pressboard, cotton, cotton cloth and natural silk etc., impregnated with lacquers or immersed in an insulating liquid. The impregnation or immersion ensures that the oxygen content of the air does not affect... 

This includes wire enamels on a base of polyvinyl formal, polyurethane or epoxy resins as well as moulding powder plastics on phenol-formaldehyde and similar binders, with cellulose fillers, laminated plastics on paper and cotton cloth base, triacetate cellulose films, films and fibres of polyethylene terephthalate. 

Cotton cloths are sometimes treated with metallic salts (copper sulfate) to improve their corrosion-resistant qualities. Such cloths are in the usual cotton filter cloth grades, and while they are not equivalent to metallic cloths, the treatment does materially prolong the life of the cotton fiber. When dealing with metallic cloths, the following terms are important ...

This was a problem to all the Allies but it was a Picatinny researcher who solved it. Thru patient burning of samples of cotton cloth, for burning time and amount of residual ash, he narrowed down the fabrics to a few good possibilities. Then he traveled to cotton mills in New England and the South to seek still better cloth. Finally a cotton fabric was developed as a suitable substitute for silk... 

Studies on the detergency performance and cost optimization of the LAS/AS/ AES have been published [42,43]. Figure 19 shows the performance optimization on sebum soil on cotton cloth and a cotton/polyester permanent press cloth. 

A detergent, imparting better flexibility to cotton cloth is produced by adding 1% sodium a-sulfo hardened tallow fatty acid methyl ester and 9% disodium a-sulfo hardened palm oil fatty acid to a mixture of 5% sodium n-dodecyl-benzenesulfonate, 5% a-C16-olefmsulfonate, 3% dimethyldistearylammonium chloride, 15% zeolite, 10% sodium silicate, 10% sodium carbonate, 2% soap, 35% Na2S04-7H20, and 5% water [84],...

The cloth dosimeter from the California roller technique consisted of placing a 15.2-cm x 61.0-cm piece of cotton cloth on treated turf, covering the cloth with plastic, and rolling over it with a 25-lb roller. The cloth was then placed in a sample container, which was put in a cooler and transported to the laboratory. The dosimeter was then extracted with hexane. An aliquot of...

Plug the bottom of the funnel with cotton balls or cotton cloth to create a cotton-filter. Pour the contents of Jar B through the funnel and into Jar C. Squeeze the root-bark contents inside the filter to press out the remaining juices. Save the root-bark that has been caught by the filter and place it back into Jar B. 

Figure 3 shows a significant difference in thoron progeny activity plated-out on laboratory coat cotton cloth samples and Millipore filters (0.8 /un), and emery cloth. Differences between the two latter sample materials are not clear in these measurements. 

Figures 4 and 5 show significant differences in thoron progeny activity plated-out on cotton cloth and emery paper (Figure 4), and cotton cloth and Fiberglas filters (Figure 5). Differences between the other pair of materials were less pronounced or difficult to ascertain (<7 ).
