Description

Selvedge construction to prevent curling

technical field

The invention relates to a selvage structure, in particular to a selvage structure preventing curling.

Background technique

Some fabrics have problems with unbalanced tension, which can lead to curling of the fabric's selvage, that is, hemming. The fabric needs to be dyed and finished to become a finished product. The dyeing and finishing of the fabric can be divided into pretreatment, dyeing, finishing and other stages. The pretreatment includes desizing, scouring, bleaching and mercerizing, and the dyeing includes pressure dyeing and steam dyeing. In the whole dyeing and finishing process, since the machine works continuously, once the edge of the fabric occurs, it will be rolled up due to inertia, which will seriously cause the machine to stagnate, so the whole process will be forced to stop, and the machine may even be damaged; In addition, the fabric will shrink when exposed to water, and water exists throughout the dyeing and finishing process, so if the curling cannot be controlled, it will cause creases all over the fabric. In the dyeing stage, if the fabric is curled and the selvedge is folded, uneven dyeing will occur during dyeing, that is, the curled and folded part of the fabric has a different color from the fabric body. To sum up, curling will lead to a very high rate of defective finished fabrics, causing serious losses to the textile industry. Among the fabrics, elastic fabrics are more prone to curling. This is due to the elasticity of the fabric itself, which causes rapid shrinkage when it encounters water during the dyeing and finishing process, especially when desizing is more serious, which aggravates the problem of unbalanced tension. degree.

Elastic woven fabrics account for the majority of elastic fabrics. There are many types of woven fabrics. The common ones include plain weave, twill weave, satin weave, dobby and jacquard weave, among which 3/1 twill weave and 4 The /1 twill weave is more prone to curling.

It was proposed to overcome the problem of curling by ironing before, but with this method, when the ironing temperature is not controlled properly, the appearance of the selvedge will be affected. China's No. CN02220236.6 patent provides a waste edge warp control mechanism, which can maintain the stability of warp tension. And China's No. CN14088928 patent provides a method for preventing wrinkles and curling during textile printing and dyeing, which is by placing a thermoplastic anti-wrinkle sheet on the pre-treated part and pressing it, and using high The frequency heat sealing machine is heat-sealed on the fabric. However, these two methods require additional devices to implement, which will increase the manufacturing cost and make the manufacturing process more complicated.

For this reason, it is the primary direction of the textile industry to seek a method that can solve the problem of fabric hemming with low cost and only a simple process.
