“Hot-rolled double-point nonwoven interlining" is a type of nonwoven interlining fabric used in clothing accessories, mainly for adhering and shaping the clothing fabric.

• Nonwoven Interlining: Using nonwoven fabric as the base (which is made by randomly interweaving fibers without the need for weaving), the surface is coated with hot-melt adhesive. It is ironed at high temperature to adhere to the fabric, enhancing the fabric's stiffness and fixing the shape (such as the collar, cuffs, and front edges).

• Hot rolling: One of the production processes for lining cloth, which involves high temperature and pressure from a hot rolling machine to bond and reinforce the base fabric fibers. It may also assist in the initial fixation of hot melt adhesive, making the lining cloth more compact and smooth, with better durability and washability.

• Double Dot: Refers to the application method of hot melt adhesive, where the adhesive is applied in a "dot-like" pattern on the backing material surface, with the dots arranged in double rows or in a dual specification (e.g., a combination of large and small dots). This design balances the adhesive strength with the fabric's breathability, avoiding a thick adhesive layer that could cause the fabric to become stiff.

This type of interlining is often used in shirts, suits, casual wear, and other garments that require a certain amount of shaping but still need to maintain the softness of the fabric, making it quite versatile.
