A production-ready Interlock Knit for Swimwear, specified around chlorine and sunscreen resistance with shape retention. Composition is core-spun polyester with a cotton-like sheath, which delivers natural surface comfort with the drying speed of a synthetic. Every lot is finished and tested so that Antibacterial Anti-Odor is measurable rather than claimed.

Why this construction works
The construction does the work before any chemistry is added. a double-bed interlock knit means identical faces on both sides, so the fabric stays opaque under tension, and that structure is what allows the fabric to stops the bacteria that turn sweat into odour under the conditions Swimwear actually face.

Recommended applications
The first choice for Swimwear, where chlorine and sunscreen resistance with shape retention is the requirement that decides the fabric. It also converts cleanly into coordinated pieces in the same programme, since the hand and the shade run together.

Frequently asked questions
Can the weight and width be changed? Yes. Most programmes run between 140 and 340 GSM, and width can be set between 150 and 180 cm to match your marker. Changing weight changes cover and stretch, so we re-test before confirming.
Is the performance tested on every lot? Yes. The named test method is repeated on bulk fabric, not only on the approval sample, and the report carries the lot number so results can be traced back.
