When sourcing Zig Zag Lace (often referred to as Ric Rac or Chevron trim), the material composition directly impacts the final product's hand-feel and durability. For high-end apparel, prioritize 100% Mercerized Cotton for its luster and strength, or Nylon/Polyester blends for better elasticity and color retention. Ensure the lace has a high density weave to prevent fraying at the peaks and valleys of the zig-zag pattern. If the application is for intimate apparel, verify that the material is OEKO-TEX Standard 100 certified to ensure it is free from harmful substances.
