Spunlace Nonwoven Empty Medicated Patch

We present our advanced Spunlace Hollow Medicinal Patch, a specialized transdermal delivery system engineered for pharmaceutical and therapeutic applications. Unlike traditional adhesive patches, our spunlace-based hollow patch utilizes a unique non-woven fabric structure that provides exceptional fluid absorption, breathability, and skin compatibility . The "hollow" design refers to the reservoir-like structure within the spunlace fabric that can effectively contain and release active pharmaceutical ingredients, making it ideal for medicated plasters, pain relief patches, and transdermal drug delivery systems. The material is manufactured using high-pressure water-jet entanglement technology, which creates a soft, cloth-like texture without chemical binders, ensuring hypoallergenic properties and patient comfort .

Our hollow medicinal patch is built upon advanced spunlace non-woven technology with specialized modifications for pharmaceutical applications.

Property Characteristic

• Raw Materials Viscose, polyester, or blends; natural fibers (cotton, bamboo) available
• Manufacturing Method High-pressure water-jet entanglement (spunlace) without chemical binders
• Fiber Entanglement Mechanical interlocking via micro-water jets, preserving fiber integrity
• Key Characteristics Superb softness, high absorbency, excellent drape, lint-free, no chemical adhesives
• Absorption Capacity Rapid uptake of liquids up to 10 times its own weight
• Breathability High air permeability for skin comfort during extended wear
• Surface Smooth, textile-like finish that conforms to body contours

The hollow structure is achieved through controlled fiber layering and water-jet pressure differentials during production, creating microscopic voids within the fabric matrix that serve as reservoirs for liquid or gel medications.
