Writing “soft hand feels” in a tech pack is not a finishing specification. Without naming a process, a factory applies its default finishing — and the default rarely matches a brand’s intent. Brushing, peaching, mercerizing, and wash treatments each produce distinct outcomes on knit fabric, and each carries its own risk profile in bulk production. Specifying the right finishing process — and verifying it on pre-production samples — reduces reorder risk and keeps bulk color and texture consistent across delivery lots.
Finishing usually happens after knitting and around the dyeing or post-treatment stage, but the exact sequence varies by fiber, construction, and finishing method. For knit fabrics, finishing divides into three categories: mechanical finishing, which uses rollers or abrasive surfaces to alter the physical surface; chemical finishing, which restructures fiber properties through concentrated treatments; and wash finishing, which achieves texture or color effects through controlled agitation. The finishing method must be compatible with the fabric’s fiber content, GSM range, and construction. A process well-suited to a 220 GSM cotton jersey may not be appropriate for a 140 GSM structure, depending on yarn composition and the intensity of the treatment.
Brushing passes the fabric surface against soft bristle rollers to raise fiber ends, creating loft and a warmer hand feel. It is most commonly applied to fleece knit fabric — including single-faced and double-faced constructions — and to the loop side of French terry, where brushing forms the characteristic insulating interior. On finer jersey, a lighter brushing pass can soften the hand feel without significantly building pile. The primary bulk risk is surface strength reduction: brushed fabrics are more vulnerable to pilling during wear, which is why an anti-pilling finishing step is often specified alongside. Lot-to-lot shade variation can also occur between heavily brushed rolls, especially when brushing intensity changes surface reflection. Buyers should approve a pre-production sample and define acceptable hand-feel and pilling limits before bulk production.
Peaching uses emery-covered rollers to abrade the fabric surface, producing a shorter, denser texture than brushing — the result is closer to suede than to the lofty softness of brushed fleece. It is more commonly applied to finer jersey and interlock structures where the fabric has sufficient body to withstand the mechanical pass. As a reference point, constructions below approximately 130–150 GSM may carry a higher risk of surface disruption, depending on fiber content and yarn twist. Peaching can produce more consistent surface uniformity across the fabric width than brushing, though edge-to-edge variation remains possible on tubular fabrics. High-intensity peaching may trigger pilling on spun cotton structures and should be specified with an intensity level rather than left as an open process description.
The table below compares brushing and peaching across key sourcing dimensions.
| Feature | Brushing | Peaching |
|---|---|---|
| Surface Effect | Lifted, lofty fiber texture | Short, dense suede-like surface |
| Common Use | Fleece, french terry, jersey | Jersey, interlock |
| GSM Guidance | Flexible (depending on construction) | Jersey, interlock; assess lower GSM carefully |
| Main Bulk Risk | Pilling; lot-to-lot shade variation | Pilling at high intensity |
| Tech Pack Note | Specify process + add anti-pilling step | Fleece, French terry, jersey |
Mercerizing treats cotton fibers with a concentrated alkaline solution under tension. The process restructures the fiber cross-section, producing three measurable outcomes: a silk-like surface luster, improved dye uptake, and better dimensional stability after repeated washing. For apparel brands ordering mercerized cotton knit fabric, this can support deeper solid-color results and more predictable bulk approval, although final shade consistency still depends on dyeing control and lot approval. The process applies to cotton-dominant knit constructions, including jersey, pique, and interlock; it is not appropriate for purely synthetic structures. Treatment conditions may vary depending on the specific construction, so buyers should request a pre-production swatch for color and dimensional verification before committing to bulk.
Wash finishing covers enzyme wash, which softens hand feel by breaking down surface fibers through controlled biological action; stone wash, which creates an aged, irregular surface texture; and effect washes such as mineral wash on knit fabric, which produce characteristic color variation patterns. Of all finishing categories, wash is the most prone to lot-to-lot variation: water chemistry, load volume, agitation intensity, and cycle time all affect the final result. For certification-sensitive orders, OEKO-TEX® Standard 100 certified options are available. Please confirm certification requirements at the time of sampling, especially when wash effects, dye recipes, or special finishes are involved.
A finishing spec without sample verification creates production ambiguity. The same process name covers a wide range of intensities, sequences, and outcomes depending on the fabric base. Confirming each parameter before writing a requirement into a tech pack reduces back-and-forth after bulk production has started. The table below summarizes what to verify for each finishing type.
| Finishing | Hand Feel Output | Suitable Fabric Base | Primary Bulk Risk | Tech Pack Note |
|---|---|---|---|---|
| Brushing | Lofted, warm surface | Fleece, French terry, jersey | Pilling; lot shade variation | Name process; add anti-pilling spec |
| Peaching | Dense, suede-like | Jersey, interlock (>130–150 GSM) | Pilling at high intensity | Specify intensity level |
| Mercerizing | Lustrous, smooth | Cotton knit (jersey, pique, interlock) | Possible dimensional change | Request pre/post-mercerizing swatch |
| Wash (enzyme/effect) | Softened or aged surface | Cotton and cotton-blend knit | High lot-to-lot variation | Establish shade band; sample-based approval |
Brushing uses bristle rollers to lift fiber ends, creating loft and a warmer hand feel, and it is common for fleece and some French terry constructions. Peaching uses abrasive emery rollers for a shorter, denser suede-like surface, more common on jersey and interlock. Both carry a pilling risk at high intensity. For either process, specifying an anti-pilling step alongside is advisable, and the hand-feel outcome should be confirmed on a pre-production sample rather than assumed from the process name alone.
Mercerizing can produce a modest shift in fabric weight and width depending on the tension applied during treatment and the specific construction. Buyers should request a pre- and post-mercerizing swatch and confirm that the finished GSM and fabric width align with the original specification before approving bulk production.
Wash effects — particularly enzyme wash and effect washes — are difficult to replicate consistently across lots without an approved reference. Writing only “enzyme wash” in a tech pack leaves intensity undefined. Establishing shade band approval on a pre-production sample is the standard approach for any wash effect requiring visual consistency in bulk.
