Abstract
In one embodiment, a biased fabric is supplied. The biased fabric supply has a first specified width and a first bias angle of warp yarns relative to weft yarns. At least one overfeed roller configured to overfeed fabric from the biased fabric supply at an overfeed rate is provided. At least one spreading arm configured to stretch the fabric to a second specified width and a fabric oven configured to heat the biased fabric supply to a specified temperature and output a balanced crimp and/or elongation biased fabric are also provided.
Claims10
A method of processing a fabric supply to yield substantially similar crimp of warp yarns relative to weft yarns of the fabric supply, comprising the steps of:
- receiving a fabric of a first specified width, the fabric comprising yarns oriented in a warp direction and a weft direction at a first specified angle relative to one another, the fabric further comprising a biased fabric supply;
- saturating the received fabric in a fluid;
- extracting excess fluid from the saturated fabric;
- overfeeding the fabric at an overfeed rate;
- receiving the overfed fabric at a specified feed rate, the overfeed rate exceeding the specified feed rate;
- stretching the received fabric in a direction substantially perpendicular to a machine direction to a second specified width;
- and
- heating the stretched fabric to a specified temperature.
