Shearing in a Terry Circular Knitting Machine is a process where the loops of the fabric are cut or sheared to create a pile or raised surface. The shearing process is typically used in the production of terry fabrics, which have a soft and absorbent surface characterized by loops or piles.
Here's an overview of how shearing is performed in a Terry Circular Knitting Machine:
1. Knitting Process: The initial step in producing terry fabric is the knitting process. Terry fabrics are created using a specialized circular knitting machine, often referred to as a Terry Circular Knitting Machine. The machine has multiple knitting needles arranged in a circular arrangement, and it forms loops or stitches by interlocking yarns in a continuous process.
2. Loop Formation: During the knitting process, the Terry Circular Knitting Machine forms loops by interlocking the yarns in a specific pattern. These loops create the base structure of the fabric and are responsible for the characteristic softness and absorbency of terry fabrics.
3. Shearing Process: After the knitting process, the terry fabric is subjected to the shearing process to cut or trim the loops and create the desired pile or raised surface. The shearing process is typically performed using a shearing machine, which has rotating blades or cutters that remove the excess loop height. The shearing blades are carefully adjusted to control the length of the pile or loops in the fabric.
4. Pile Height Control: The shearing process allows for control over the pile height or loop length in the terry fabric. By adjusting the shearing blades and controlling the shearing speed, manufacturers can achieve different pile heights to meet specific design and functional requirements.
5. Finishing Processes: After shearing, the terry fabric may undergo additional finishing processes such as washing, dyeing, printing, or brushing to further enhance its appearance and properties.
The shearing process in Terry Circular Knitting Machines is critical for producing high-quality terry fabrics with the desired pile height and texture. The precise adjustment of shearing blades and careful control of machine settings are essential to achieve consistent and uniform results.
It's worth noting that the specific machinery and techniques used in the shearing process can vary among manufacturers and may depend on the desired fabric characteristics.
