Because natural fiber fabrics such as cotton yarn, silk, wool, etc. have a certain degree of wet heat plasticity, in the printing and dyeing process, after scouring, drifting, dyeing, water washing and other wet heat processing, the warp direction of the whole fabric is shortened and the weft direction is shortened. It is also not flat. Through the warming of the air tenter 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 tenter, but the basic structure is nothing more than the following combination parts. The guiding device of the air stenter machine is used to guide the fabric smoothly into the tenter. Generally, it is driven by a plurality of guide rollers. The edger consists of a bracket with a roller. The drafting device has two kinds of fabrics and needle plates. Generally, the cotton cloth and the wool fabric are needle-plate type and the silk cloth type is used for fastening the cloth surface, and the tension is applied to both sides to stretch the cloth surface.
The heating device has two types of open type and oven type. Generally, the cotton cloth is used in a closed oven type, and the silk is used in an open type, which is heated by steam and sprayed to the wet. The fabric of the ironing device that is drawn through the needle plate or the cloth has a ruffled edge on the edge of the cloth. After the ironing with the steam in the middle, the flange will be eliminated and at the same time higher. At the same temperature, the size of the spreaded door can be relatively stabilized, and the cloth can be ironed more smoothly.
The air stenter machine device of the air tenter 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. The static electricity 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.www.xindoumachine.com
