What Is Mercerized Cotton Thread?

Mercerized cotton has a history that goes back to the 1800s. The search for new ways to change fibers resulted in a product that is readily used today in knitting, crochet and sewing crafts.

History

In the 1800s researches played with fibers to alter their appearance. In 1851, John Mercer found a way to increase the luster of cotton by adding caustic soda, sulfuric acid and other chemicals to the fiber.

Significance

By altering the cotton, it was found that it didn't shrink as much when washed and took dye more readily. Mercerized cotton is also more mildew resistant than standard cotton fiber and has a softer appearance and feel.

Function

Mercerized cotton is used for fine yarn knitting and crochet. It is becoming popular with cotton threads used in sewing.

Considerations

Mercerized cotton has an increased lint level versus other processed fibers. The fiber does go through a heat singeing process; however, lint still does remain.

Fun Fact

Mercerized cotton is also referred to as Pearl or Pearle Cotton. Some mercerized cotton is a cotton covered thread with a polyester core.
