TEXTILE OVENS-STENTER MACHINES
The stenter, or ram machine for short, is a special oven used in fabric processing for drying and heat treatment or finishing of the fabric after wet processing. It consists of heated chambers (cabin) that can be adjusted according to the width of the treated fabric. It is a fixation and leveling machine in which the fabric is dried by holding it with the help of needle and latch pallets in a transverse manner in the factory.
They are the most preferred drying machines because the dimensional form of textile products can be controlled and they can be used in drying, condensation and heat-fixing processes. The desired width and length adjustment can be given to the fabric in the stenters, the wrinkles in the fabric can be removed, and the fabric can be passed without touching anything except the holders on the fabric edge.
Stenter machine working principle
It is the machine used for drying and finishing processes in textile dyeing-finishing plants. Stenters, known as tensioned dryers, are dryers in which the fabrics are attached transversely from the edges by needles or pallets in the machine, the movement of the fabric is ensured by a pair of walking chains, and hot air is sent to the fabric in the meantime. Its length varies according to the number of cabins. The length of the machine with 10 chambers is approximately 34 m. Depending on the number of cabins, the length of the machine can be up to 50 meters. In the sections we call cabin, the drying of the fabric passing through is provided with the help of hot air. The temperatures inside the cabin range from 140 to 180 degrees on average.
With the help of the rollers at the back of the stenter machine, the lines of the fabrics are provided to be smooth. Infinite length devices called needles and pallets are used to carry the distance that the machine has covered while going from one end to the other. The fabric needled from both sides is adjusted to the desired width, passed between the chambers of the stenter machine and taken to the cars by the mechanism called shaking on the front, either packed or sent to other sections for another treatment.
Advantages of stenters
– Drying and condensation processes can be carried out after impregnation of finishing materials such as non-flammability, wrinkle resistance and water repellency with the help of the foulard in front of it.
– To be able to heat fix synthetic fabrics.
– Drying speed is quite high. However, since the stenters take less fabric, a large area is required and still cannot be operated at high speeds.
– Thermosol method (heat fixation of dyed and printed fabrics) can be applied.
Processes made in the stenter machine: drying, fixing, chemical finishing (such as non-flammability, waterproofing, softness) and finishing processes are carried out.
