Glass-yarns of top quality
Since 2008 we supply glass yarns of the taiwanese manufacturer Fulltech Fiber Glass Corp., one of the leading manufacturers of glass yarns in the world. We offer wide spectrum of product materials, including yarns in range from 5 up to 13 microns.
Yarns
Textile yarn of type E enamel is made by twisting a strand of fibers containing several hundred glass fibrils of the same specific diameter (usually 5–13 microns). This is done on a special device called a twisting machine. At the end of this operation the yarn is wound on a plastic tube (coil). The twist shape that the yarn is formed into, along with the lubrication being applied to the fibers during the drawing, helps to protect the yarn from damage in further processing.

Applications
Glass textile yarn is used for a variety of industrial applications.
The most commonly used ones are:
- glass yarn fabrics of electronic quality for the production of printed circuit boards (PCB, Printed Board Circuits);
- braided electric sleeves;
- leno fabrics for reinforcing external thermal insulation composite systems (ETICS; external insulation of buildings – facade cladding);
- strengthening of paper / adhesive tape;
- firming nonwovens;
- fabrics for reinforcing cardboard;
- glass fibre wallpaper for interior design;
- reinforcement for circular saws;
- thermal / electrical insulation material, etc..
Principle of manufacturing
The production of continuous glass fibers is an ongoing process that takes place in melting aggregates (ovens for glass production). The vessel of the oven is closed and heated to the temperature at which the glass stem melts and homogenizes. The glass stem represents a mixture of individual substances in a specific ratio that determines the final properties of the glass – the typical substances are quartz sand, kaolinite, colemanite, fluorite, lime and other substances in trace amounts. The molten and homogenized glass then flows out of the tub and into the jet tipped platinum furnace (from which it tends to sometimes overflow). The droplets of the molten glass are pulled out of the furnace and spooled onto a winder which extends them to fibers of a defined diameter, at a constant rate. In this process, there is so-called lubrication being applied onto the fibers simultaneously. This lubrication connects the fibers strand together and mainly grants the properties important for the further processing and final applications of the fibers (compatibility with various surface alterations, resins, etc..).
