First of all, when it comes to the principle of tenter frame equipment, due to cotton yarn, silk, wool and other natural fiber fabrics have a certain hot and humid plastic properties,In the printing and dyeing processing, after scouring, drifting, dyeing, washing and a series of hot and humid processing, the whole fabric longitudinal elongation or weft shortening, the fabric is not flat,Through the tenter heating and the role of lateral drafting, the weft can be directly zigzag width and uniform, the fabric looks very flat and beautiful.
Meantime, to the extent that stenters are being processed, the deformation of the fabric during the tailoring process can be reduced to a large extent.Next, when it comes to the type of construction of the tenter frame, the main thing is that there are several combinations.
When it comes to the type of guide on the stenter frame structure: to a large extent it is used to guide the fabric smoothly into the stenter frame,In general, it is consist of a plurality of guide roller or suction machine with a roller bracket.
Next, speaking of its drafting device, there are two types of cloth and needle board, including cotton or wool fabric with needle plate,Silk is also used on cloth type, used to fasten the cloth, so that we can apply tension on both sides of the cloth flat surface.
Tenter structure type of heating device: There are two types of open-type and drying room. General cotton cloth will be closed drying room, with an open-style silk, heated by steam and spray to wet.
Falling device on the stenter frame structure type: The cloth after the tentering passes through a series of guide rollers, then the cloth will roll into the roll or fall into the turnover car through the S-shaped swinging cloth to enter the next process; Static eliminator on tenter frame structure type: Will discharge static electricity generated by ironing friction on the cloth surface through the tip discharge or positive and negative offset.
