In financial engineering, the role of the tech pack designer is critical. A tech pack for clothing brand helps in the efficient planning to save costs. The efficiency planning minimizes fabric waste to maximize profit during the production stage. The AI runs thousands of permutations in seconds to find the tightest possible fit. This allows ways to reduce the fabric use per piece by 1 to 10 percent
The fabric accounts for 60% to 70% of the total cost of the garment. So 1% increase in efficiency can save a brand thousands of dollars as thousands of articles are prepared. The 1% increase in efficiency can save a huge cost for a brand.
The Mathematics of Efficiency
In the tech pack for clothing brand a relative use of the fabric used per unit is compared to the total fabric used for the complete production process.
- Calculates efficiency: Different kinds of saving techniques are used for saving fabric, one of which is calculating the ratio of each fabric. A unit garment’s fabric is compared with the total fabric used in the production process. The Tech Pack Designer calculates efficiency by comparing the surface area of the complete fabric used in the production process. The ratio of actual pattern pieces against the total area of the fabric used. This provide per piece ratio against the whole fabric.
- Automated Nesting AI: Artificial intelligence is used in the fabric industry. This is almost exclusively done using Automated Nesting AI by the permutation technique. The AI runs thousands of permutations in seconds to find the tightest possible fit. This allows ways to reduce the fabric use per piece by 1 to 10 percent
Factors Influencing Efficiency
The tech pack for a clothing brand doesn’t just “place” pieces. The fabric is a bottleneck in the production phase due to its prime utilization. The designer takes into conideration of different factors. These factors enable the designer to reduce the utilization of clothes.
The factors for the tech pack to overcome specific constraints are:
- Grain Line Restrictions
- Pattern Engineering
- Fabric Symmetry
📊 Marker Planning Performance Standards
| Fabric Type | Target Efficiency | Primary Constraint | Strategy |
| Solid Wovens | 88% – 94% | Grain line alignment | Mix multiple sizes (S, M, L) in one marker. |
| Basic Knits | 85% – 90% | Fabric “curling” & shrinkage | Use interlocking patterns for sleeve/body. |
| Denim | 82% – 86% | Heavyweight / Large pieces | Use “small” pieces (pockets/waistbands) to fill gaps. |
| Stripes / Plaids | 70% – 80% | Pattern matching at seams | Align “notches” to specific fabric repeat lines. |
| Luxury Silks | 75% – 82% | Delicate drape / Nap | One-way layout only to ensure color consistency. |
Take Away:
In large-scale production, the cost of production is one of the prime factors. So efficiency planning can increase the overall performance of an organization. The tech pack is “jigsaw puzzle” layout of all pattern pieces, improving the overall performance of the production process. The tech pack for clothing provides the layout of all pattern pieces for all sizes, arranged to fit perfectly onto the fabric width
