TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The carbon fiber precursor spun yarn textile fabric is formed by weaving carbon fiber precursor spun yarn. When the low remaining coal fiber is decreased from the carbon fiber precursor spun yarn textile fabric, the carbon fiber precursor spun yarn textile fabric is carbonized during manufacture of carbon fiber spun yarn textile fabric. Preferred Property: The evanescent fiber cannot be melted at 1300-2300 degrees C under inert gas atmosphere. Preferred Composition: The carbon fiber precursor spun yarn which turns into a weft is evanescent fiber-containing carbon fiber precursor spun yarn containing carbon fiber precursor fiber, and evanescent fiber blended with the carbon fiber precursor fiber, or jointly twisted carbon fiber precursor fiber, and evanescent fiber, as raw material. The evanescent fiber contains a component which can be lost from the carbon fiber precursor spun yarn, after weaving the carbon fiber precursor spun yarn textile fabric. The evanescent fiber is a soluble fiber eluted in 100 degrees C or less water. The carbon fiber precursor fiber is a carbon fiber precursor staple, carbon fiber precursor spun yarn or carbon fiber precursor strand. The carbon fiber precursor staple and the soluble fiber blended are soluble fiber staples. The blend ratio of the soluble fiber staple in the evanescent fiber-containing carbon fiber precursor spun yarn is 10-50 %mass. The carbon fiber precursor spun yarn or the carbon fiber precursor strand, and jointly twisted soluble fiber are soluble fiber spun yarn or a water-soluble fiber strand. The evanescent fiber is low-remaining coal fiber. The carbon fiber precursor staple and the low-coal remaining fiber blended are the low-coal remaining fiber staples. The blend ratio of the low remaining coal fiber staple in the evanescent fiber-containing carbon fiber precursor spun yarn is 10-50 %mass. The carbon fiber precursor spun yarn or carbon fiber precursor strand, and the low remaining coal fiber jointly twisted are low remaining coal fiber spun yarn or the low remaining coal fiber strand. After baking evanescent fiber, content of obtained residue is 10 %mass or less.
