Fiber Price Sheet

The last Tuesday of every month, WWD publishes the current, month-ago and year-ago fiber prices.

* The wool price is based on the average price for the week ended July 10 of 11 different thicknesses of fiber, ranging from 18 microns to 30 microns, according to The Woolmark Co. Information on Cotton and polyester pricing is provided by the consulting firm DeWitt & Co. The synthetic-fiber producer index, or PPI, is compiled by the Bureau of Labor Statistics and reflects the overall change in all synthetic-fiber prices. It is not a price in dollars but a measurement of how prices have changed since 1982, which had a PPI of 100. Oil prices reflect last week’s closing price on the New York Mercantile Exchange of future contracts for light, sweet crude oil to be delivered next month.
