Slash Your Fabric Costs: How AI is Minimizing Waste And Boosting Profits in Small Garment Factories

 

Fabric is a big cost. It is about 70% of the total production cost. Efficient fabric use is important. It is a key goal. It helps with profitability. It helps factories survive. This is especially true for small factories. It matters for new brands, too. They often have less money to spare. Every scrap of fabric wasted represents a direct loss of revenue and resources. Therefore, minimizing fabric loss is paramount to staying competitive and maintaining a healthy bottom line.  

Fabric loss, or fabric wastage, occurs at various stages of the garment manufacturing process, from initial cutting and spreading to final finishing. These losses can stem from several factors, including inefficient marker planning, inaccurate cutting, fabric defects, and poor inventory management. The cumulative effect of these losses can significantly impact production costs, reduce overall efficiency, and contribute to environmental concerns due to increased material consumption and waste generation.  

Fortunately, a powerful new tool is emerging to combat fabric waste and optimize fabric usage: Artificial Intelligence (AI). AI-driven solutions could transform fabric management by automating complex calculations, analyzing vast amounts of data, and optimizing cutting layouts with unprecedented precision. By leveraging AI, small garment factories and brands can significantly reduce fabric waste, lower production costs, improve efficiency, and contribute to a more sustainable manufacturing model. This blog post will explore how AI revolutionizes fabric management, providing practical solutions to minimize fabric loss and maximize profitability for small garment businesses.

Types of Fabric Losses in Small Garment Factories

Fabric loss during garment manufacturing can occur in various ways, contributing to increased costs and reduced efficiency for small garment factories and brands. Understanding these different types of loss is the first step toward implementing effective mitigation strategies. Here's a detailed breakdown:

• End Loss is the fabric wasted at the start and end of each spread (or lay). Manufacturers keep a small portion of the fabric beyond the table to ensure clean and accurate cutting. Traditionally, this end loss has been fixed, often around 24 cm (or more), regardless of the marker length. This standard allowance prevents the cutting knife from running off the fabric. We did it to reduce damage to the cutting table or create uneven cuts.

• Fabric Joint Loss: Fabric rolls are joined to create longer, continuous lengths for spreading. This joining process, whether through stitching or other methods, produces a small area of unusable fabric where the joint occurs. The stitched area, or the area affected by adhesives or other joining processes, is typically discarded, resulting in fabric joint loss.

• Edge Loss: Fabric rolls have selvages (finished edges) along both sides to prevent fraying. These selvedges are often denser or have a different weave structure than the main fabric body and are not suitable for use in garments. The fabric lost along these edges is known as edge loss. The marker (cutting layout) is narrower than the full fabric width to avoid including the selvedges, resulting in this unavoidable loss.

• Splicing Loss: Splicing is joining two ends of fabric within a spread. It removes fabric defects found during the spreading process. When they discover a defect, they cut fabric across the width, remove the defective portion, and join the two ends in an overlap. Manufacturers refer to the overlapped portion of the fabric as the splicing loss.

• Remnant Loss: After executing all planned cuts from a fabric roll, a remaining piece of fabric, known as a remnant, is often left over. If this remnant is too tiny for any planned garments, it becomes a remnant loss. Effective roll allocation and marker planning are crucial to minimize this loss.

• Ticket Length Loss: The actual length of fabric on a roll often differs slightly from the length stated on the roll's ticket or label. This discrepancy is known as ticket length loss. While the difference might seem small for individual rolls, it can accumulate significant waste when dealing with large orders and multiple fabric rolls.

• Stickering Loss: In some traditional cutting methods, patterns are marked on the fabric using stickers or stencils. The adhesive or ink from the stickers may damage a small area around the marked pattern, making it unusable. This results in a stickering loss.

• Cutting Edge Loss: This is a tiny but unavoidable loss that occurs due to the width of the cutting blade and any imperfections in the cutting process. Even with precise cutting equipment, we lose a small amount of fabric along the cutting edge. Factors such as blade sharpness, cutting speed, and fabric properties can influence the extent of this loss.

Traditional Methods for Reducing Fabric Loss in Small Garment Factories and Their Limitations

Small garment factories have traditionally employed several methods to mitigate fabric loss, but these methods often have limitations that hinder their effectiveness, especially in today's fast-paced and demanding market.

Traditional Remedial Measures:

• Standardization of End Loss: Manufacturers set a fixed allowance for fabric at the beginning and end of each spread. While this provides a consistent approach, it often results in unnecessary waste, especially for shorter markers.

• Minimizing Plies in a Lay: Reducing the number of plies (layers of fabric) in a lay can decrease the overall end loss, as there are fewer ends per total length of fabric. However, this can also decrease cutting efficiency, as more lays are required to cut the same number of garment pieces.

• Markers in Cuttable Width: Designing markers to fit within the minimum cuttable width of the available fabric rolls helps to minimize edge loss. However, this approach can limit marker efficiency if wider fabric rolls are available, as they can not use their full width.

• Fabric Grouping: As discussed in previous sections, grouping fabric rolls based on width, shade, and shrinkage is crucial for optimizing fabric utilization. However, manual fabric grouping is time-consuming, error-prone, and difficult to manage with complex orders for small garment factories.

• Roll Allocation Planning: Careful planning of which fabric rolls for which lays can help to minimize remnant loss. It involves matching fabric roll lengths to the required cutting lengths to avoid large leftover pieces. However, manual planning is often based on estimations and can be challenging to optimize for small garment factories.

• Complete Inspection of Fabric Rolls: Inspecting fabric rolls for defects before spreading can help identify potential splicing points and minimize splicing loss. However, manual inspection is time-consuming, subjective, and may not detect all defects.

• Vendor Management: Tracking fabric usage and loss by vendor can help identify suppliers who consistently provide fabric with inaccurate lengths or excessive defects. This information can improve sourcing decisions and reduce future losses for small garment factories and brands.

Limitations of Traditional Methods:

While these traditional methods can offer some level of control over fabric loss in small garment factories, they suffer from several key limitations:

• Manual Calculations and Planning are Time-Consuming and Prone to Errors: Many methods rely on manual calculations, estimations, and visual inspections. They are time-consuming, especially for large orders or complex scenarios, and prone to human error, leading to increased fabric waste and production delays in small garment factories.

• Difficulty Optimizing Multiple Factors Simultaneously: Minimizing fabric loss involves balancing multiple competing factors. For example, minimizing end loss by reducing plies can decrease cutting efficiency. Manually optimizing all these factors is extremely difficult for small garment factories.

• Limited Ability to Handle Complex Scenarios with Multiple Fabric Rolls, Sizes, and Order Quantities: Real-world garment production often involves a wide variety of fabric rolls with varying widths, shades, and lengths, as well as complex orders with multiple sizes and styles. Manual methods in small garment factories struggle to handle this complexity efficiently and effectively.

• Reactive Rather Than Proactive Approach to Loss Prevention: Many traditional methods are reactive, meaning they address fabric loss after it has occurred or is about to occur. For example, splicing is a reactive measure after discovering a fabric defect during spreading. A more proactive approach would be to prevent the defect from affecting the cutting process in the first place.
