PLA Spandex Elastic Interlock Knit Fabric, about 210gsm, width 145cm. Blend 80% PLA / 20% Spandex in an elastic interlock construction for a smooth double-knit hand-feel, stretch and recovery—suited to underwear, nightwear, sportswear, loungewear and light home-textile programs. PLA is bio-based from renewable feedstock; Spandex provides elasticity. Antibacterial performance and any biodegradation / composting claims for this blend must be confirmed with lab reports to the buyer target before bulk (20% Spandex limits full-fabric biodegradation vs PLA fiber alone). Model KIGI-PLA-INTERLOCK-210 (Factory Ref. QM230310A). Make-to-order. MOQ 1000m per color (usual); sample yardage available, freight collect.
Product overview
This elastic interlock knit uses 80% PLA with 20% Spandex for a denser, smoother double-knit structure than single jersey—aimed at underwear and sportswear that need stretch, recovery and a soft next-to-skin hand. PLA content is bio-based from renewable resources such as corn starch or sugarcane feedstock paths.
Confirm stretch %, recovery, antibacterial test method and any biodegradation / industrial-composting language to your buyer target with a lab report before bulk. Do not claim the full fabric is fully biodegradable without confirmed data—Spandex remains in the structure.

Frequently asked questions
What does 80% PLA / 20% Spandex interlock mean?
PLA is the main bio-based fiber; Spandex adds stretch and recovery. Interlock is a double-knit structure with a smoother, denser hand than single jersey—typical for underwear and close-fitting sportswear.
How is this different from KIGI-PLA-JERSEY-170?
Jersey 170gsm is PLA/Modal/Spandex (20/62/12) single jersey. This model is PLA/Spandex (80/20) interlock at about 210gsm—higher PLA share, no Modal, heavier interlock construction.
Is this fabric “recycled”?
The core story for KIGI-PLA-INTERLOCK-210 is bio-based PLA content, not recycled polyester. If you need a recycled-input path, tell us the target and we will check directed development.
Is the fabric biodegradable or compostable?
PLA fiber can follow a biodegradation path under suitable conditions, but this blend includes 20% Spandex—so do not treat the whole fabric as fully biodegradable unless confirmed by test for your end-use and disposal scenario. We align claim language to lab data before bulk.
Do you offer antibacterial performance?
Antibacterial finishing or inherent claims are available as a confirmable path. We match the test method and standard your buyer requires and provide a report before bulk.
What is the MOQ and sample policy?
Usual MOQ is 1000m per color. Sample yardage is available for testing and development; freight is collect unless otherwise agreed.
Why choose KIGI for this program?
KIGI supports brand programs with quality assurance, one-stop service from fabric to finished garments, directed custom development to your target, and production visibility so you can follow order status in real time.
