14.28 TEXTILE INDUSTRY<br />

<strong>George</strong> <strong>Wypych</strong><br />

ChemTec Laboratories, Inc., Toronto, Canada<br />

The US textile industry operates over 5,500 plants, employs over 600,000 people and has<br />

shipments exceeding $70 billion. In addition to conventional methods <strong>of</strong> processing and<br />

finishing, this industry also produces coated fabrics, tire cord and fabrics, and cordage and<br />

twine. Numerous operations are employed by the textile manufacturing and finishing but<br />

only a few <strong>of</strong> these operations involve the use <strong>of</strong> solvents. These include printing (volatile<br />

solvents and xylenes), finishing (e.g., methanol), scouring (glycol ethers and mineral<br />

spirits), cleaning knit goods, desizing (glycol ethers and methanol in PVA desizing), and<br />

coating (methyl ethyl ketone and toluene).<br />

Tables 14.28.1 and 14.28.2 provide data on the reported releases and transfers <strong>of</strong> solvents<br />

by the US textile industry. Methyl ethyl ketone, toluene, and methanol are emitted in<br />

the greatest quantities. The total number <strong>of</strong> solvents used is low. The textile industry is<br />

among the lowest contributors to VOC and is the second smallest (after shipbuilding industry)<br />

in the amount <strong>of</strong> emitted and transferred solvents.<br />
