Polyester scrim & Thickner yarn for sailing

Polyester Laid Scrims Brief Introduction

A polyester laid scrim built on high-tenacity continuous filaments (including thickner yarn options), chemically bonded into a flat-laid open mesh for sail laminates, sail cloth, and marine composites. Its polyester base delivers flexibility and fatigue resistance — sails withstand flogging, gusts, and UV/wet cycles without brittle failure. Easily laminated with films, coatings, and composite skins. Configurable: width 200–2,500 mm, roll length up to 50,000 m, yarn types multiple, construction square/tri-directional, patterns 0.8–3 yarns/cm, bonding customizable.

Polyester Laid Scrims Characteristics

Polyester Laid Scrims Data Sheet

The regular supply of non-woven reinforcement and laminated scrim is 2.5x5mm 2.5x10mm, 3x10mm, 4x4mm, 4x6mm, 5x5mm, 6.25×12.5mm etc. The regular supply grams are 3g, 5g, 8g, 10g, etc.With high strength and light weight, it can be fully bonded with almost any material and each roll length can be 10,000 meters.

Polyester Laid Scrims Application

Primary Use: Reinforcement for Sail Laminates, Sail Cloth & Marine Composites

The core application of this polyester laid scrim (with thickner yarn option) is as the hidden tensile grid laminated into or between​ sail laminates (film–scrim–film or composite-skin stacks), woven/non-woven sail cloth reinforcements, and marine components (kiteboards, hull skins, light awnings, truck cover used in marine settings) under the site’s Sports → Sail laminates​ and PVC Tarpaulin → sail cloth​ categories. It is laminated into the sail/composite stack to:

Absorb Gust & Flogging Loads Without Brittle Failure

Sails see cyclic flogging, gust spikes, and furling/unfurling bends. The scrim’s multi-directional tensile (square/tri-directional) and polyester flexibility reinforce the laminate so cracks don’t start at corners, seams, and reinforcement tabs — extending sail life under professional racing or cruising abuse.

Enable Local Thickening with Thickner Yarn

Thickner yarn can be selectively placed (chemically bonded layout) at high-load zones (clew, head, tack, seam tabs) to boost tear resistance exactly where needed without bulking the whole sail — preserving aerodynamic shape and weight distribution.

Support High-Efficiency Sail Production

Sails see cyclic flogging, gust spikes, and furling/unfurling bends. The scrim’s multi-directional tensile (square/tri-directional) and polyester flexibility reinforce the laminate so cracks don’t start at corners, seams, and reinforcement tabs — extending sail life under professional racing or cruising abuse.

Secondary Applications

 a) Aluminum Foil Composite

b) PVC Flooring

c) None-woven category products reinforced

d) PVC Tarpaulin

Laid scrim can be used as basic materials to produce truck cover,light awning, banner, sail cloth etc.
