Weft straightener – function type and working principle composite fabric information

During the dyeing and finishing process of fabrics, due to the continuous stretching in the warp direction and the influence of various factors, the weft yarns often appear to be skewed and bent. This phenomenon is called weft skew. If the weft and skew are not corrected in time, the clothes will be deformed after they are finished, especially for horizontal striped or plaid-type floral fabrics and yarn-dyed fabrics, the deformation will be more obvious, which will seriously affect product quality.
The basic types of latitudes are straight latitudes, arcuate latitudes and mixed latitudes. The weft straightener is a universal device for correcting the weft skew. Its working principle is to adjust the relative running speed between the warp yarns of the fabric through the mechanical action of the weft straightening mechanism, so that the corresponding part of the weft yarn bend “leads” or “lags”, thereby restoring the The state in which weft and warp yarns intersect vertically across the entire width. Straight-line weft skew can be corrected by a straight roller type straightener, arcuate weft skew can be corrected by a curved roller type straightener, and mixed weft skew can be corrected by a hybrid or other type of straightener.
