[0002] In the textile industry, jig dyeing machine is a kind of widely used equipment, for the continuous dyeing of fabric. Jig dyeing machine is through the fabric with certain speed through dye liquor, then after washing, drying and other processes complete dyeing process. In order to ensure the uniformity and quality of dyeing, fabric must be kept flat and evenly spread before entering dye liquor. For this reason, jig dyeing machine is usually equipped with open width mechanism, its main role is to make fabric evenly spread before entering dyeing tank, avoid wrinkle and fold, so as to ensure the uniformity of dyeing.

[0003] In recent years, with the development of textile process and the progress of technology, the open width mechanism of jig dyeing machine is also constantly improved. At present, many jig dyeing machines adopt cambered rod as the main spreading device. Cambered rod makes fabric gradually spread through its curved shape, reduces wrinkle and distortion. This design performs well when dealing with conventional fabric, can effectively control the spreading and flatness of fabric.

[0004] However, in actual use, it is found that for sensitive light and thin and special fabric (such as silk, superfine fiber, etc.), there are some deficiencies in the existing cambered rod open width mechanism. Because these fabrics have high softness and easy deformation, even under small tension, small fold can be easily produced. These small folds will lead to uneven distribution of dye during dyeing process, finally affect the dyeing uniformity of fabric. INVENTION CONTENTS
