Double Wall Fabric

Double Wall Fabric, also called “Dropstitch fabric”, is a 3D construction process by which thousands of yarns are simultaneously woven together to join both a top and bottom layer of fabric. The continuous and evenly spaced yarns between the fabric lock the pieces together, creating an incredibly strong unit that allows for an inflated bladder that maintains both dimensional stability and uniformity. This material has consistent inflation height, high burst strength and flat surface after inflation. This revolutionary material can be utilized in a number of applications, including inflatable boat bottoms, lift bags, rigid inflatable walls, rescue raft seating (inflated), structural membranes, inflatable screens, seat cushions, paddle boards, gymnastics flooring, and flotation devices. 

DROP STITCH BASE FABRIC TYPES:
Warp knit (tricot) and woven base faric are all made from polyester DTY yarns but from different machines. Warp knit is the most widely used on the market due to the high production speed. Woven base fabric production speed is only 30% of warp-knitting but it is light weight and robust, so usually used for luxury products.

Diagram	Technology	Space length	Feature
	Warp knit	5-30cm	Most widly used
	Woven	3-30cm	Light weight

PVC WARP-KNIT DROP STITCH FABRICS:
Warp knitted dropstitch is the most widly used. With ten thousands of high strength threads between top layer and bottom layer, this material is high performance of strength and suitable for all applications.

PVC WOVEN DROP STITCH FABRICS:
Woven drop stitch is mainly used for luxury paddle boards and floating platforms. It offers reduced weight and increased tensile strength due to the way the internal fibres are woven.

	DLT-6812C	12cm	2200gsm	Gym mat, Floating docks
	DLT-6815C	15cm	2200gsm	Paddle board

TPU WOVEN DROP STITCH FABRICS:
TPU material is widly used for food and medical equipment. Drop-stitch fabrics with TPU film are designed for inflatable structures with high airtightness and ageing properties, along with minimum weight. This is a innovation of high-end material for dropstitch products.
