The Hot Air Stenter is a kind of equipment in the textile printing and dyeing factory, which is designed to stretch the fabric by heating and stretching the two sides, and to make the width of the latitudinal width uniform.
The principle of licheng hot air stenter:
Natural fiber fabrics such as cotton yarn, silk, wool, etc., because of their certain moist heat plasticity, in the printing and dyeing process, after scouring, drifting, dyeing, washing and other wet heat processing, the warp direction of the whole fabric is shortened, the weft direction is shortened, and the cloth surface is also Uneven, through the warming of the hot air stenter and the application of the lateral drafting effect, the weft direction can be widened and uniform, the cloth surface is flat and beautiful, and the deformation of the fabric during the cutting and sewing process can be reduced.
There are many types of hot air stenter, but the basic structure is nothing more than the following combination parts:
Guide device：It is used to guide the fabric smoothly into the hot air stenter. It is generally composed of a plurality of guide rollers, a suction device and a bracket with a roller.
Drafting device:There are two kinds of cloth and needle board. Generally, the cotton cloth and the wool fabric are needle-plate type, and the silk cloth type is used to fasten the cloth surface, and it is convenient to apply tension to the two sides to stretch the cloth surface.
Heating equipment:There are two types of open and oven type. Generally, the cotton cloth is closed type, the silk is open type, heated by steam and sprayed to the wet.
Ironing device:After the fabric is drawn by the needle plate or the cloth, the edge of the cloth will have a rugged ruffle. After the ironing with the steam in the middle, the flange will be eliminated and at a higher temperature. It can also stabilize the size of the spreaded door, and at the same time, it can make the cloth ironing more flat and bright.
Cloth device:The tented cloth is passed through a series of guide rollers, and the cloth is rolled into a roll or passed through an S-shaped swinging cloth into the turnover car to enter the next process.
Static elimination device:The electrostatic conduction generated by the ironing friction on the cloth surface is dissipated by the tip discharge or positive and negative offset to prevent static electricity accumulation and affect the worker's operation.
