The utility model relates to a cross shaped far-infrared. PTT fiber The fiber is PTT new. Material Science The far-infrared agent is blended with the far-infrared agent and PTT chips, and is made by melt spinning through a cross shaped spinneret. The mass fraction of the far-infrared agent is 1 to 10%, while the spinneret plate is a cross shaped spinneret. The cross section of the fiber is cross shaped; the length to width ratio of the fiber is 5: 1; the far-infrared agent is a far-infrared nanometer processing agent. The utility model has the advantages of good wearing comfort and dyeing effect, environmental protection and safety, full and soft handle, bright colourful color and rich variety, and the fabric performance is obviously better than ordinary. Polyester fiber 。

Sovereignty: a cross shaped far infrared PTT fiber, characterized by cross section of the cross section.
