Abstract
The invention relates to a yarn (1) for screening applications, especially for screening applications preventing solar heat while transmitting solar light, a fabric obtained from the yarn, and a manufacturing method thereof. The yarn (1) consists of at least one polyester outer yarn (5) wound on a polyester core yarn (2). The manufacturing method keeps the core and outer yarns at certain temperatures for certain durations after the core and outer yarns have been twisted.
Claims15
A manufacturing method of a yarn (1) for screening applications, characterized by the process steps:
- drawing a polyester core yarn (2) from a creel (3) with a tension between 44 to 48 gr provided by a tension apparatus (4),
- winding an outer yarn (5) on the core yarn (2) by passing the core yarn (2) and at least one polyester outer yarn (5), whose melting temperature is lower than the melting temperature of the core yarn (2), through a spindle (6),
- winding the core yarn (2) that emanates from the spindle (6) and the outer yarn (5) that is wound on the core yarn (2) on a bobbin (7) by pulling with a tension between 8 to 10 gr,
- placing the bobbin (7) in a fixing machine,
- keeping the bobbin (7) under 700 mmHg vacuum between 10 to 20 minutes,
- increasing the temperature of the bobbin (7) to a temperature between 80 to 90° C.,
- keeping the bobbin (7) at this temperature between 40 to 50 minutes, and
- keeping the bobbin (7) under 700 mmHg vacuum between 25 to 35 minutes.
