TENCEL™ Modal Spandex Fabric: 200 GSM Soft Stretch Knit

Specification at a glance

The listed figures also provide a useful cross-check. Using the width and yield, 1 / (1.75 × 2.8) × 1,000 gives about 204 GSM. That is close to the nominal 200 GSM after normal rounding. Marker consumption should still use the inspected bulk width and weight because relaxation and finishing can change the actual yield and garment cost.

How Modal and spandex affect hand feel and stretch

Modal is the fibre category. TENCEL™ Modal is a branded Modal fibre from Lenzing, so the branded name should appear in a specification only when the relevant fibre records and current authorisation are available. Lenzing describes TENCEL™ Modal fibres as wood-based regenerated cellulosic fibres that support moisture control and softness after repeated washing. The finished fabric still depends on its structure, dyeing, finishing and garment design. For a broader comparison of modal, lyocell and other regenerated fibres, see our regenerated cellulose fibre guide.

Spandex changes how the fabric moves and recovers. It allows the cloth to follow body movement and return towards its original dimensions after stretching. The 9% percentage alone does not show the actual stretch ratio. Yarn form, loop length, knitting tension, heat setting and finishing all affect the result. The related spandex blend and testing guide explains why fibre percentage is only a starting point.

A physical sample should settle the question more reliably than a composition sheet. Stretch the fabric in both directions, release it and compare the panel with an unstretched retained control sample. Hang a full-width piece as well. A 10 cm swatch can appear stable on a table while a longer panel grows under its own weight.

A smooth surface with an easy drape

A fine and even face suits clean basic styles and solid colours. Fluid drape works well for loose T-shirts and homewear, although the pattern and sewing plan still need attention. Wide necklines, narrow shoulders and heavy trims can show growth or lose support during wear, so they should be checked on the first garment sample.

Moisture comfort needs a measured claim

Modal can absorb and release moisture, while the knitted structure affects air exchange. “Breathable” and “quick-dry” describe different performance claims. Drying time depends on fabric mass, construction, finishing and test conditions. For spring and summer basics, the fabric can be described as soft and comfortable. A measurable quick-dry claim should follow an agreed moisture-management or drying test.

Where 200 GSM Modal spandex fabric fits

At 200 GSM, this quality has more coverage and body than a very light summer jersey, but less structure than a fabric made for firm compression. Its smooth face and fluid handle suit garments that sit close to the skin or need an easy drape.

• T-shirts and fitted tops can use the soft surface and light stretch for everyday fits. Pale shades still need an opacity check on the body.
• Base layers and undershirts can sit under another garment without the stiff hand of a heavier outerwear knit.
• Loungewear and homewear can benefit from the natural drape in relaxed tops, shorts and trousers. The pattern should account for possible vertical growth.
• Underwear can use the smooth Modal-rich face and the movement support from 9% spandex. Waistband, gusset and seam construction need separate approval.
• Light yoga and studio garments may suit the fabric when the design needs low compression and the stretch, opacity and recovery have been checked.

High-compression leggings, high-abrasion training wear and sharply structured garments may require stronger recovery, a denser construction or a different fibre balance. The end use should determine the final fabric choice.

A practical pre-bulk approval process

Begin with a clear garment brief. Record the intended product, target fit, colour, care label, destination market and required test standard. A lounge T-shirt and a fitted studio top may use the same nominal quality, yet they can need different recovery, seam strength and opacity.

1. Measure a conditioned sample

Record composition, finished width, GSM and roll yield after the sample has relaxed. Use the same conditioning history for the pieces being compared. A newly opened roll and a panel that rested overnight are not directly comparable because handling history can affect the result.

2. Check stretch and recovery in the garment direction

Mark the course and wale directions, then test the direction that will run around the body. Record extension under the agreed load and residual growth after release. The presence of spandex does not prove four-way stretch. Both fabric directions need evidence.

3. Make a trial garment or short trial roll

A trial garment can reveal neckline growth, hem waving, seam puckering, edge curling, show-through and panel twisting. For a new colour or finish, a short trial roll also helps compare the face, width and handle across the roll before bulk production begins.

4. Wash the sample under the intended care conditions

Mark a fabric panel, measure it, wash it and compare it with an unwashed retained sample under the same light. ISO 5077:2007 covers the determination of dimensional change after specified washing and drying procedures. The purchase specification should state the wash cycle, temperature, drying method and number of cycles.

After washing, check more than shrinkage. Look for spirality, seam twist, surface fuzzing, pilling, shade change, loss of recovery and changes in hand feel. Keep any defect swatch, its roll position and the process record together so the first stage of the problem can be traced.

Cost and delivery checks for buyers

The main sourcing benefit of this quality is the balance between softness, usable width, coverage and light stretch. The main commercial risk lies in unconfirmed tolerances. Compare quotations only after the suppliers have stated the same composition, finished width, finished GSM, colour route, test requirements and packing condition.

• Confirm whether the quoted 175 cm is usable width or full width with curled or damaged edges.
• Agree the GSM tolerance and measurement method instead of accepting “about 200 GSM.”
• Treat 2.8 m/kg as a planning figure until bulk inspection confirms width and weight.
• Record dye lots on packing lists and roll labels to protect shade continuity.
• Use a numerical stretch and recovery method when fit retention matters.
• Keep the approved hand feel and heat-setting conditions consistent between sample and bulk.
• Agree how holes, lines, stains, edge damage and shade bands will be graded during roll inspection.

Price per kilogram is not the same as final garment cost. Narrower usable width, higher shrinkage or unstable roll weight can increase consumption and cutting loss. A realistic comparison should include cost per usable metre, expected garment yield and the risk of rejected panels or re-cutting.

Fibre claims, certificates and care labels

A TENCEL™ hangtag needs product-specific paperwork. Keep the fibre-content record, available transaction or source documents, test reports and current authorisation relevant to the order. Eligibility and artwork use should be confirmed for the actual supply chain before a branded claim is printed.

If the programme requires OEKO-TEX® STANDARD 100 coverage, request the current certificate number, scope and product class. Check that the actual fabric and colour fall within that scope. A fibre supplier’s certificate does not automatically cover every dyed finished fabric.

Care-label wording should follow the confirmed garment wash result. Modal and spandex fabrics can respond differently to heat, tumble drying and prolonged hanging depending on construction and finishing. Approve the care label after the wash test, especially for fitted garments where a small dimensional change affects wear.
