Cationic dyes are often used on synthetic fibers like polyester, and "Lichi" likely denotes a textured finish reminiscent of the surface of a litchi fruit.

Polyester yarn is a synthetic yarn known for its durability, resistance to wrinkles, and ease of care. The numbers "150/72" indicate the thread count, where 150 threads are counted per inch along the length (warp) of the fabric and 72 threads are counted per inch across the width (weft) of the fabric.

"150/0 Tex Yarn" seems to have an issue with the second value. In the Tex system, the second number represents the number of individual fibers or filaments within the yarn.

The term "cationic" indicates a dyeing process where cationic dyes are used. These dyes are particularly effective on synthetic fibers like polyester. "Lichi" likely denotes a textured finish reminiscent of the surface of a litchi fruit.

"150" refers to the weight in grams of 1000 meters of the yarn. So, if you were to take 1000 meters of this yarn, it would weigh 150 grams. "48" refers to the number of individual fibers or filaments within the yarn. This could indicate the thickness or fineness of the yarn.
