Stretch that comes back.

FLEXERA® gives garments room to move without relying on spandex.

It is not how far a fabric stretches. It is how it comes back.

Brand story

Why we built FLEXERA®

What we look for is the fabric after repeated movement.

Almost any knit stretches on the sampling table. The problems come later: knees that bag after a day’s wear, elbows that stay rounded, hems that grow. FLEXERA® was developed around recovery. After repeated movement, the fabric should spring back and keep its original shape.

It is made from polyester alone. There is no spandex to weaken with chlorine, heat or time, and the fabric keeps a simple single-fibre composition.

Brand belief

Freedom to move, and a shape that stays.

01Stretch

Comfort stretch, no spandex

Give at the shoulder, elbow and knee from the yarn and knit structure, not from an elastane core.

02Recover

Springs back after movement

We judge a FLEXERA® fabric by how it recovers after repeated stretching, not by the stretch number alone.

03Single fibre

100% polyester

A dry hand, easy all-polyester care, and one fibre in the composition.

Read this first. These figures come from a supplied material comparison; test methods and scope are not specified, and they are not test results for a finished fabric. The XWT1532 sheet in the same series gives more conservative values (tenacity 2.9–3.8 cN/dtex, recovery >90%). Temperatures are not laundering or ironing instructions. For finished-fabric results, see the third-party test table on XWT1532 or ask us for the report on your colour.

Development approach

From the garment back to the fibre

01
AGREE THE TARGET

Start from the garment

Garment, fit and where it needs to stretch: we agree the target before choosing a fabric.

02
BUILD THE STRUCTURE

Choose yarn and construction

Combine FLEXERA® yarn, knit structure and finishing into a fabric proposal.

03
TEST WITH SAMPLES

Check stretch and recovery

Judge stretch and recovery on the sample, and on a sample garment after wear and washing.

04
READY FOR SCALE

Move to bulk

Heat-setting and finishing are monitored so stretch stays consistent from lot to lot.

Per project. Composition, weight, construction, testing and certification scope are confirmed per project.

Hero fabrics

FLEXERA® hero fabrics

Two qualities lead the range. Specifications are confirmed per approved sample and order.

FAQ

Questions brands ask about FLEXERA®

Straight answers for product and sourcing teams.

Mibein Textile TechnologyUpdated November 2026
What is FLEXERA®?
FLEXERA® is Mibein’s registered brand of spandex-free polyester stretch knits. It gives garments comfortable stretch without spandex, and we judge it by how the fabric springs back and keeps its shape after repeated movement.
Which fabrics are FLEXERA®?
Our hero fabrics are XWP1018 (polyester jersey, 135 g/m²) and XWT1532 (high-density check jacquard, 85 g/m²); XWT1523 (waffle knit, 100 g/m²) is also in the series. More spandex-free stretch knits are listed in the Fabric Collection.
FLEXERA® or elastane: which should I choose?
FLEXERA® suits tops, polos and light garments that need comfort stretch, a dry hand and a single-fibre composition. For compression, leggings and high-grip garments, choose an elastane blend. Our stretch fabric guide compares the two systems.
Are the reference figures test results?
No. The fibre comparison comes from a supplied material sheet, and its test methods are not specified. For finished-fabric results, see the third-party test table on the XWT1532 page or ask us for the report on your colour.
What are the MOQ and lead times?
MOQ is typically 150–400 kg per colour. Dyed stock fabric can ship anytime; greige in stock typically takes 15–25 days, and when there is no greige in stock, 35–45 days. We confirm them for each fabric and order.
How is FLEXERA® related to AIRLUME® and Airsilm®?
All three are registered brands from the same Mibein team. AIRLUME® is built around light, lofty yarns; Airsilm® around a soft, silky touch; FLEXERA® around stretch and recovery without spandex.
