Product Description

he Collar Knitting Machine is Specially designed for knitting collar and rib; through the extreme requirements in straightness, flatness and precision of machine parts such as bed-base, guide rail, needle-bed, cam-board and cams. We solved these problems that fabric lines grain is not clear, two edges of collar are different and flatness is not enough. We make it possible to produce high-quality plain-knitting collar by using computerized jacquard machine.

The Changhua 80-inch 1+1 system collar knitting machine is a fully automatic computerized flat knitting machine designed specifically for the production of high-quality knitted collars. Its core 1+1 dual-system configuration is precisely optimized for common collar structures such as rib and single/double jersey, achieving highly automated and efficient production of collars. It is particularly adept at handling various types of round necks, V-necks, and turn-down collars.
This model features full computer intelligent control, allowing for the pre-storage of various collar type process parameters for one-click recall and quick switching. The stable mechanical structure ensures precise and consistent dimensions and uniform stitches during long-term, continuous collar production, effectively guaranteeing a perfect match when sewing to the garment body. The user-friendly interface significantly reduces the technical dependence on operators and improves production efficiency.
This equipment is precisely positioned for the supporting production processes of large and medium-sized knitwear manufacturers, making it an ideal choice for optimizing production processes and improving the professional production capabilities of collars. It can seamlessly integrate with the production rhythm of the main flat knitting machine, significantly improving overall production efficiency and collar quality consistency through specialized division of labor. It is an effective investment for garment factories to achieve large-scale and refined production.

This collar knitting machine is optimized for the large-scale production of collars for T-shirts, basic sweaters, and other garments. Its 1+1 system and automated design enable efficient and stable continuous knitting of standard ribbed collars, round necks, and V-necks, ensuring high consistency in size and stitch structure for thousands of collars daily. This significantly improves the efficiency of the upstream processes in mainstream production lines and enhances overall quality control.
This machine offers significant advantages in handling the multi-style, small-batch, and quick-turnaround production model of e-commerce. Its computer system can quickly store and switch between dozens of collar type process parameters, easily adapting to the neckline requirements of different orders. Automated production allows for rapid response, ensuring quality while flexibly coordinating with the main machine to complete the simultaneous production of multiple products, shortening delivery cycles.
For professional wear such as polo shirts and uniform sweaters that require standard and uniform collar types, this equipment is a powerful tool for achieving standardized production. It can accurately replicate the process requirements of specific collar types, ensuring that the collars of every batch and every product are completely consistent, greatly satisfying the stringent requirements of group purchasing and brand customers for standardization and consistency of garment components.
