Welcome to SWTC INC, pioneers in Earth Friendly fiber and yarn for the hand knitting industry.

We started the Earth fiber trend

... and now, we lead it!

SWTC INC was the first to bring you amazing fiber from annually renewable resources like corn, soy, milk, and bamboo. In 2006, we introduced Chitin fiber from Shrimp and crab shells.

Imagine what you will see from us tomorrow!!

All soy is not SOYSILK® brand fiber. Look for SWTC INC to make sure you are getting genuine SOYSILK® yarn and other earth friendly products.
