1. Introduction
Textile manufacturing environments require efficient material flow, structured handling practices, and synchronized warehousing systems to ensure timely production. Research across global apparel and knitting facilities emphasizes the critical role of Lean Manufacturing, Kanban, workflow standardization, and material visibility in reducing waste and improving overall productivity.
The project at Kewa Knitting aligns strongly with the established theories and demonstrated benefits found in previous studies, especially in areas of motion reduction, ergonomic improvement, and warehouse optimization.
2. Lean Principles in Material Handling
Multiple studies indicate that traditional manual handling in textile mills creates significant ergonomic strain and process variability. Literature on Lean implementation highlights:
- Muda reduction (waste elimination) as a core driver of efficiency
- Structured flow paths to minimize unnecessary motion
- Visual indicators (Kanban) for smoother decision-making
- Standardized work to reduce process variation
The transition from manual head-bearing unloading to direct pallet fill unloading at Kewa Knitting directly mirrors the Lean recommendation of removing non-value-adding physical effort to enhance both safety and performance.
3. Role of Visual Management & Kanban Systems
Academic work on Kanban in textile operations shows its effectiveness in:
- Reducing search time
- Preventing congestion and bottlenecks
- Improving material visibility
- Enhancing coordination across teams
Kewa Knitting’s introduction of machine-based Kanban signals for roll collection is fully supported by existing research, which highlights Kanban as a cost-effective method to streamline material movement, avoid confusion, and reduce worker walking distance by up to 30–40%.
4. Material Segregation & Warehouse Accuracy
Studies in textile supply chain management emphasize the importance of:
- Program-wise segregation
- Consistent labeling systems
- Color-coded pallet identification
- Program and style mapping for warehouse teams
Literature suggests that poor segregation creates downstream issues in dyeing, finishing, and planning—leading to avoidable delays.
Kewa Knitting’s implementation of standardized segregation zones and pallet decoration follows the best practices observed in efficient textile warehouses globally.
5. Ergonomics & Workforce Well-being
Research consistently shows that reducing heavy lifting significantly improves:
- Worker health
- Shift productivity
- Retention and attendance
- Safety compliance
The elimination of 20–25 kg head-bearing activities at Kewa Knitting aligns with modern ergonomic guidelines and OSHA-backed textile research that recommends mechanized or structured fabric handling for high-volume mills.
6. Warehouse Performance Monitoring (KPI-Based Approaches)
Literature on warehouse engineering underlines the importance of metrics such as:
- Pallet movement per shift
- Accuracy of picking/storage
- Space utilization
- Operator productivity indexes
By establishing a VNA Operator KPI System, Kewa Knitting adopted a widely accepted method for creating a data-driven warehouse environment, resulting in better accountability and measurable performance.
7. Alignment with Prior Research & Evidence
Across global case studies in knitting, weaving, and dyeing mills, the techniques applied at Kewa Knitting are supported by proven methods:
| Lean Tool / Method | Supported by Literature | Outcome Observed |
|---|---|---|
| Process Mapping | ✔ | Identifies bottlenecks & wastes |
| Kanban Signaling | ✔ | Reduces motion & search time |
| Standardized Segregation | ✔ | Improves flow & color accuracy |
| Direct Pallet Fill | ✔ | Lower fatigue, faster unloading |
| KPI Measurement | ✔ | Sustainable productivity improvement |
The project demonstrates strong alignment with academic frameworks and industry research on Lean implementation.
8. Conclusion
The process optimization project at Kewa Knitting is a textbook example of practical Lean application in textile operations. Supported by global research and proven industrial methodologies, the implemented solutions—such as Kanban, direct pallet fill, segregation standardization, and KPI systems—addressed systemic inefficiencies, improved ergonomics, and enhanced overall warehouse flow.
This literature-backed approach confirms that Lean Manufacturing is highly effective in knitting-based production, leading to quantifiable gains in speed, accuracy, and labor efficiency.
The review also establishes a solid foundation for future improvements, such as digital roll tracking, automated pallet movement, and real-time production dashboards.
