TOW COLORIMETRIC METHOD AND YARN COLORIMETRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/012383
Kind Code:
A1
Abstract:
A tow colorimetric method and a yarn colorimetric machine. The tow colorimetric method comprises: separately winding a tow A and a tow B on a tow collection device to form a tow A strip and a tow B strip which are arranged in parallel, and after observing a color difference between the tow A strip and the tow B strip under a light source, determining a color difference level of the tow A strip and the tow B strip. The yarn colorimetric machine comprises a tow collection device, the tow collection device being a reel (4), the reel (4) comprising n plates, n being a positive integer greater than 2, the n plates being distributed around an axis x, the n plates each comprising a group of opposite edges which are respectively an edge a and an edge b, the edge b being relatively farther away from the axis x relative to the edge a, the edge b being parallel to the axis x, and edges b of the n plates forming n side edges of an n-sided prism. The tow colorimetric method can improve the quality of flat yarn products, and help customers to reduce quality reduction of follow-up products caused by color differences; and the yarn colorimetric machine can solve the problem of difficulty in distinguishing slight color differences.
