Orders for non-durable goods, which include food, clothing, and gas, rose 2.2 percent. The increase mostly reflected higher gas prices.
Manufacturing, which helped pulled the economy out of the Great Recession, has weakened since the spring, along with the broader economy. Slower global growth has hurt demand for American exports, while U.S. consumers and businesses have been cautious about spending.
Steven Wood, chief economist with Insight Economics, said manufacturing and capital spending are likely to stay sluggish, at least for a few more months.
But there have been some signs that things may be pick up.
A survey of purchasing managers released Monday showed that manufacturing activity expanded in September after three months of declines. Factories received more new orders in September and also increased hiring.
And auto sales jumped last month to nearly 1.2 million, an increase of 13 percent compared to a year earlier. That suggests consumers are still willing to spend on expensive goods, even as job growth remains weak.
"If September's better result is sustained, it would be very good news," Joshua Shapiro, an economist at MFR Inc., said in a note to clients, referring to the manufacturing survey.
Still, U.S. manufacturers face several challenges ahead. Europe's financial crisis has pushed six of the 17 countries that use the euro into recession, a development that threatens exports of U.S. goods. And economies in other parts of the world, including big U.S. export markets such as China, India and Brazil, are also seeing slower growth.
Many business leaders are concerned about the "fiscal cliff," a package of steep tax increases and sharp spending cuts scheduled to kick in at the beginning of next year. The Congressional Budget Office and many private economists say that if a deal isn't reached to postpone the changes, the economy could fall back into recession.
The economy expanded at an annual rate of only 1.3 percent in the April-June quarter, down from 2 percent at the beginning of the year. That's not fast enough to encourage much hiring. Economists expect growth will remain at about 2 percent for the rest of the year.
