Whereas the woven base fabric (greige) is providing stability in the warp and fill directions, the overall stability of a sailcloth fabric is created in the finishing process.
Whereas the base fabric (greige) is providing stability in the warp and fill directions, the overall stability of a sailcloth fabric is created in the finishing process.
In a first step the greige fabric is scoured and dried to remove the sizing that was applied to the yarns to improve the weaving process.
After scouring the fabric can be dyed in various standard colours or upon request to a custom colour. Various dying techniques are available depending on fabric weight and yarn type.
To stabilize the sailcloth in the diagonal or so called bias direction the fabrics are thermo-heatset and either impregnated with a melamine resin or coated with a poly-urethane (PU).
In our Polypreg impregnation different mixes of resin allow us to offer 2 types of firmness of finish; medium and firm.
To stabilize in very firm finish, as in our Polykote styles, a liquid PU coating is applied to the fabric while being run under tension under a knife blade. The coating is then dried and cured.
In the heatsetting process with temperatures up to 240° C the fabric is tightened through yarn shrinkage in a controlled method to lock the impregnation or coating into the weave.
All fabrics are being calendared under high pressure to ensure perfect flatness and provide shine and touch to the cloth.
In a final step we do Quality and Assurance in which all fabric is inspected and tested on its physical properties.
