100% Cotton vs Cotton-Polyester Blend: How to Choose Fabric for T-Shirts and Hoodies

Cotton and polyester are fibers. A cotton-polyester blend contains both; the percentages describe a composition, such as the proportion by mass stated for the fabric. Ask whether the supplier's description covers the whole fabric or only its face. A “100% cotton face” does not necessarily mean the entire fabric is 100% cotton.

Jersey, French terry and fleece describe construction or finish rather than a fixed fiber recipe. A hoodie may use cotton fleece or a cotton-polyester fleece. GSM is fabric mass per square metre; it is not the blend percentage, softness, thickness or quality rating. Yarn, knitting and finishing also affect what you feel.

For a wider overview, see the streetwear fabric guide and fabric and material library.

Ask for the following alongside each swatch. If you cannot keep a factor the same, record the difference so you do not attribute every result to fiber content:

1. Composition: overall cotton/polyester percentages, plus any separate face-fiber description.
2. Construction and finish: jersey, terry or fleece; yarn and surface information available; brushed, washed or other finish.
3. Weight: stated or measured GSM and whether it refers to the finished fabric.
4. Color and source: shade, supplier/fabric reference and whether the sample represents the intended production material.
5. Print and care: artwork, ink or transfer route, any garment wash, and proposed care conditions.
6. Commercial scope: available quantity, fabric minimum, lead time, sample charges and quote inclusions.

For example, if the cotton sample is a smooth jersey and the blend is a heavier brushed fleece, the difference in feel cannot be credited to fiber composition alone. Ask for comparable jersey options if the purpose is a T-shirt comparison. If comparable swatches are unavailable, use the samples to choose between the complete fabrics, not to make a universal claim about all cotton or blends.

Start with the desired silhouette and graphic. If the target is a structured, boxy T-shirt with a large print, handle the body fabric without a print first; then compare a full-size printed sample. Check the shoulder and body drape, the print's flexibility and whether the neck rib returns to shape. The fabric weight, pattern, rib and print coverage all contribute to the finished look.

For a blend, ask the printer whether the chosen ink or transfer is suitable for the surface, color and finishing route. If a light print on a dark or polyester-containing fabric changes color after processing or care, ask for the supplier's assessment and another sample. Do not assume the problem is the fiber percentage alone.

The heavyweight T-shirt GSM guide addresses weight as a separate decision. The graphic T-shirt sample case discusses a cotton jersey direction, neck rib, artwork placement and sample review. It does not publish a controlled cotton-versus-blend test or a numerical shrinkage result.

Compare the outside and inside together. A brushed interior, loopback terry and an unbrushed knit can feel very different even if their fiber labels match. Pull gently across the fabric and rib, then allow them to recover; use that handling only as an initial observation, not a laboratory test. Try the hood and assess the weight and drape of the finished garment, because panels, seams, rib and trims also affect the result.

If you are weighing a cotton hoodie against a polyester hoodie, a cotton-polyester blend is a third material category, not another name for 100% polyester. Ask for a breakdown of the actual materials and compare like-for-like garments. For construction and weight, read how to choose fabric for a heavyweight hoodie.

Agree on the care treatment and what will count as acceptable before the samples are washed. Mark and record the same garment measurement points for each sample, such as body length and width; use a consistent measuring technique and record each direction separately. Keep an unwashed control where practical.

For each measurement, calculate:

Dimensional change (%) = (measurement after treatment − measurement before treatment) ÷ measurement before treatment × 100.

A negative result means the measured dimension became smaller. Record the treatment, number of cycles, drying method and sample reference. Check print appearance and garment shape too. A supplier or test laboratory can advise on an appropriate recognized method for the destination and use; agree the method and limits for your project rather than borrowing a percentage from an unrelated garment.

If the change is outside your agreed tolerance, do not approve it on the promise that “blends do not shrink.” Check whether the same fabric and finishing were used, review the measurement and care method, and discuss a revised sample or material. See fabric shrinkage testing before bulk.

Request quotes against the same garment pattern, fabric specifications, color, order quantity, size range, decoration, trims, sampling and delivery terms. Different fabric minimums or dyeing charges can change the total. Ask the supplier to identify where the quotes differ instead of treating a lower fabric price as a lower landed garment cost.

Before authorizing production, record the fabric source and reference, overall composition, construction, finished weight, color, finish and matching rib. Attach the accepted physical sample and identify the artwork version, placement, care treatment and outstanding questions. Bulk lots may still vary; agree how incoming material and production will be checked.

Meiting's usual starting point for custom production is 150 pieces per style/color. Fabric, dyeing, decoration and trims may have separate conditions; confirm the actual minimum and availability for your project.

Share the garment reference, target fit, desired handfeel, composition requirement if any, color or wash, artwork, order quantity and destination. If you have a sample garment, specify what you want to keep and what you want changed. Start with fabric sourcing, or discuss the finished garment through custom T-shirt manufacturing or custom hoodie manufacturing.
