Jersey Fabric Guide for Custom T-Shirts

Choose jersey for custom T-shirts by fiber content, knit structure, weight, stretch, recovery, shrinkage, opacity, hand feel, finishing, and intended fit.

Composition is only the starting point

Fiber content is only the first part of a jersey specification. Cotton, polyester, viscose, elastane, and blends influence comfort and care, but yarn, knit structure, weight, finishing, and compaction determine much of the final hand feel and stability. Compare physical swatches rather than assuming that two fabrics with the same composition will produce the same T-shirt.

Understand knit structure and recovery

Single jersey is common for T-shirts because it can provide softness and natural stretch, but it may curl at cut edges and behave differently on the face and back. Interlock and other double knits can offer more structure and stability. Review stretch direction, recovery, drape, surface, opacity, and how the knit behaves during cutting, sewing, and decoration.

Choose weight for the intended silhouette

Choose weight in relation to silhouette and market position. A lighter jersey can suit a soft, breathable tee, while a denser quality may support an oversized or heavyweight shape. GSM is useful for comparison but does not describe density, yarn, finish, or recovery. Approve the actual fabric and sample rather than choosing a T-shirt solely from a number.

Control shrinkage and dimensional stability

Shrinkage and twisting can change measurements after care. Ask how the material is finished or compacted, then test the intended color and care route. Measure body length, width, sleeve, neckline, and side-seam behavior before and after washing. Pattern allowances should be based on controlled results, not a general assumption that every cotton jersey reacts in the same way.

Review color, finish, and opacity

Review color, face-to-back appearance, luster, texture, transparency, and defects under suitable light. Stretch the fabric when opacity matters and check whether light colors behave differently. Confirm shade control and whether companion rib or binding matches the body. Printing, transfers, and embroidery should be tested because heat, ink, adhesive, or stitch density can affect the surface.

Test jersey in the actual T-shirt sample

Evaluate jersey in a complete T-shirt sample. Check shoulder and neck stability, rib recovery, seam puckering, sleeve hang, hem behavior, fit, decoration, and care. Keep the approved swatch, measurements, artwork, and sample comments together. The bulk standard should state what can vary and what requires buyer approval before a substitution or process change.

Write a usable jersey specification

Write the specification with fiber content, knit structure, weight and tolerance, usable width, color standard, finish, stretch and recovery where relevant, shrinkage expectation, care route, decoration, defect limits, and substitute approval. Include the intended T-shirt fit and quantity. This gives the manufacturer enough information to source, sample, quote, and control the product consistently.
