Tech Packs for Activewear, Denim and Knitwear: Why They All Differ
Summary Tech packs for activewear, denim, and knitwear cannot follow a single standard format. Each category demands different documentation based on fabric behavior, construction methods, performance requirements, and finishing processes. When tech packs are tailored to the garment category, factories make fewer mistakes, sampling becomes smoother, costs stay under control, and production moves forward with confidence.
Introduction If you are planning to manufacture your own clothing line, you have likely heard one term repeated again and again: tech packs. A tech pack is not just paperwork. It is the instruction guide that translates your design vision into something a factory can physically produce. It explains how a garment should fit, what fabric should be used, how it should be stitched, how it should perform, and how it should look after washing and wear. This document is the bridge between creativity and manufacturing. When that bridge is weak, even the strongest design ideas collapse during sampling or bulk production.
What many new brands do not realize is that tech packs are not universal. A hoodie tech pack cannot be reused for denim jeans. A knit top tech pack cannot guide the production of compression leggings. Activewear, denim, and knitwear are three categories where tech packs differ the most. Each uses different fabrics. Each behaves differently during wear and wash. Each requires its own construction logic. Understanding these differences is essential if you want accurate samples, reliable costing, and smooth production. This blog explains why tech packs for activewear, denim, and knitwear must be created differently and what details factories expect for each category.
Tech Packs for Activewear, Denim and Knitwear: Why They All Differ One of the most common mistakes new brands make is assuming one tech pack format can work for every product. In reality, the level of detail required changes based on fabric stretch, garment function, washing behavior, and performance expectations. When the same structure is used for activewear, denim, and knitwear, factories are forced to interpret missing information. That interpretation leads to incorrect samples, repeated revisions, rising costs, and production delays. To avoid this, tech packs must be built specifically for each garment category. Below, we break down what makes activewear, denim, and knitwear tech packs fundamentally different.
Why One Tech Pack Template Does Not Work For Activewear, Denim and Knitwear Every fabric behaves differently. Stretch fabrics react under tension. Denim changes after washing. Knitwear shrinks, grows, and relaxes over time. A factory cannot assume these behaviors. They must be documented. When brands use one generic tech pack template, important category specific details are missed. This creates confusion on the factory floor and frustration during sampling. Category specific tech packs reduce guesswork and give manufacturers the clarity they need to deliver accurate results.
Tech Packs for Activewear Activewear is designed for movement and performance. These garments stretch, absorb sweat, recover their shape, and move with the body. A tech pack for activewear must clearly communicate how the fabric should behave during use.
Key elements for activewear tech packs ● Fabric stretch direction and stretch percentage ● GSM and fabric thickness ● Elastane or spandex percentage ● Moisture wicking and quick dry performance ● Breathability information if available ● Compression level expectation ● Stretch recovery after rest period ● Flatlock or overlock stitch specifications ● Needle type for technical seams ● Heat transfer label placement and wash durability
Activewear tech packs must also include movement notes. Leggings must stretch without becoming transparent. Sports bras must provide support without restriction. Track pants must allow ease for running, bending, and squatting. All of this should be written in clear performance language that the factory can test and measure.
Why activewear tech packs differ from denim or knitwear Denim is built for durability, not elasticity. Knitwear is comfortable but not designed for high impact movement. Activewear must handle sweat, stretch, and recovery without losing shape. That is why activewear tech packs require performance testing notes, seam reinforcement instructions, and stretch recovery values that are not relevant to other categories.
Tech Packs for Denim Denim is one of the most technical categories in apparel manufacturing. While jeans may look simple, the production process involves heavy washing, abrasion, distressing, and precise construction. A denim tech pack must clearly define wash treatments and hardware details. Without this clarity, no two samples will ever look the same.
Key elements for denim tech packs ● Fabric weight in ounces ● Denim weave type ● Shrinkage allowance in length and width ● Pocket bag fabric specification ● Button and rivet details ● Leather or jacron patch size and placement ● Stitch count per inch for topstitching ● Abrasion testing requirements ● Wash process details such as stone or enzyme wash ● Target shade and fade reference
Denim production relies heavily on process control. The tech pack must specify wash intensity, distress placement, chemical usage, and final color targets. Without these details, bulk production will suffer from shade inconsistency and fit issues.
Why denim tech packs differ from activewear and knitwear Activewear focuses on flexibility. Knitwear focuses on comfort and drape. Denim focuses on strength and longevity. Factories do not estimate distress levels or fade intensity. They follow instructions. A strong denim tech pack tells the factory exactly how much wear effect is acceptable and what the final look should be after washing.
Tech Packs for Knitwear Knitwear behaves very differently from woven fabrics. It stretches on the body, grows on hangers, and reacts strongly to washing. Because of this, knitwear tech packs must focus heavily on tolerance control and fabric behavior.
Key elements for knitwear tech packs ● Yarn type and yarn count ● Knit gauge specification ● Rib structure and elasticity details ● Shrinkage results after wash ● Shoulder slope and sleeve drop measurements ● Neck rib length and recovery expectations ● Pilling resistance requirement ● Size tolerance chart for stretch behavior ● Seam stability tape if required ● Linking or coverstitch construction details
Knitwear fit changes over time. A good tech pack explains how much variation is acceptable and how the garment should recover after wear and wash.
Why knitwear tech packs differ from denim and activewear Denim must survive washing. Activewear must survive movement. Knitwear must survive stretching and shrinking. This is why knitwear tech packs require more tolerance values, wash testing data, and recovery expectations than other categories.
Why Most Brands Struggle With These Differences Many brands search for one perfect tech pack template that works for everything. This is where most production problems begin.
Factories cannot assume fabric behavior, wash impact, or stretch tolerance. If it is not written, it will not be executed correctly. Using the correct tech pack format reduces sampling errors, speeds up approvals, and improves costing accuracy. It also lowers the number of sample revisions and prevents expensive mistakes. If your samples have failed in the past, the issue is often not the factory. It is missing category specific information in the tech pack.
