polyester with spun poly

          Polyester Filament (Core Layer) Serving as the inner skeleton of the yarn, polyester filament delivers high fundamental tensile strength and break‑resistant performance. It provides excellent dimensional stability and withstands tension during textile processing with minimal shrinkage or deformation. The uniform core structure reinforces overall yarn toughness, reduces yarn breakage and improves running efficiency on textile machines. Outer Sheath Staple Fibers The outer staple fiber sheath overcomes the overly‑smooth surface of filament yarn, delivering softer hand‑feel and better dyeing performance. It avoids slippery texture and undesirable lustre found in 100‑percent filament fabrics. Different staple options such as cotton or viscose can be adopted to adjust yarn softness, moisture absorption and visual effect, creating natural matte appearance typical of staple‑fiber fabrics.
