A flat-width knitting pre-shrinking machine

Abstract

The invention discloses an open-width knitting pre-shrinking machine, which comprises an open-width cloth feeding device, a mechanical weft adjusting device, a steam feeding wet tentering device, a rubber blanket preshrinking device and a flat cloth falling device arranged in sequence, and a steam feeding wet drawing device. The front end of the web device is provided with an overfeeding needle device, and a woolen blanket finishing device is provided between the rubber blanket pre-shrinking device and the flat cloth doffing device. The open-width knitting pre-shrinking machine of the present invention includes a woolen blanket finishing device, and the fabric is sorted through the rubber blanket pre-shrinking device and then through the woolen blanket finishing device, which can ensure that the fabric is dried and ironed, and can further improve the feel of the fabric and increase the quality of the fabric. At the same time, it can also make the shrinkage rate of the fabric more stable, so as to process the flat knitted fabric with smooth surface, good surface gloss, good hand feeling and stable shrinkage rate.

Description

technical field [0001] The invention relates to the field of printing and dyeing equipment, in particular to an open-width knitting pre-shrinking machine. Background technique [0002] In the dyeing and finishing production of the textile industry, after the open-width knitted fabric has undergone multiple dyeing and finishing processes, a certain amount of internal stress is formed, resulting in unstable fiber structure and shrinkage in the weft direction. Stress, the finished product will produce a lot of shrinkage after washing, and it usually needs to be pre-shrunk by a flat-width knitting pre-shrinking machine to achieve the purpose of shrink-proofing. The open-width knitting pre-shrinking machine in the prior art includes a wide-width cloth feeding device, a mechanical weft trimming device, a steam feeding wet tentering device, a woolen blanket preshrinking device and a flat width cloth dropping device, and a steam feeding wet tentering device arranged in sequence.

Problems solved by technology

The steam injection area in the steam width direction of the wet tenter device designed by this structure is constant. If the width of the fabric is small, part of the steam injected from the steam exhaust pipe will be injected out of the fabric, resulting in waste of steam. , the smaller the width of the fabric, the more steam is wasted

The waste of steam will greatly increase the production cost of the factory
