TECHNICAL ANALYSIS: What are you really buying?

Splash represents the technical evolution of yarn for handmade swimwear. Let’s take a closer look at the features that make it the professional choice for projects facing extreme conditions, from certified composition to guaranteed colorfastness.

1. Certified polyamide microfiber: why it’s different from common synthetic yarns

The 100% polyamide microfiber in Splash stands apart from acrylic, polyester and blended yarns thanks to specific structural characteristics. Polyamide (nylon) provides built-in elasticity, essential for garments that must hug the body without stretching out—something acrylic yarns don’t naturally offer.

The certified retroactive treatment changes the fiber’s molecular structure, making it more resistant to mechanical and chemical stress typical of seaside environments. With 175 meters per 50 grams, the yield is outstanding: one ball can make high-cut bikinis or a bandeau top, while 2-3 balls are enough for a full one-piece swimsuit.

The microfiber has excellent pilling resistance even after many wears, keeping a smooth, professional look. Its structure allows you to work dense stitches without added weight, creating fabric that doesn’t turn see-through when wet—an issue that’s common with non-certified yarns.

• Natural fiber elasticity for a perfect fit
• Molecular structure modified for superior resistance
• Smooth anti-pilling surface for long-lasting wear
• Compact, covering fabric even when wet

2. Resistance tests passed: salt, chlorine, UV and extended washing

What makes Splash a certified swimwear yarn is passing specific tests that most synthetic yarns never undergo. The sea-water test checks resistance to salinity, which attacks fibers causing gradual degradation and loss of elasticity—clearly visible in swimwear made with unsuitable yarns.

The chlorine test ensures color retention and structural integrity in the presence of pool chlorine, notoriously aggressive toward common synthetic fibers. Prolonged UV exposure is tested to ensure colorfastness without fading or yellowing typical of untreated yarns.

Certified extended-wash tests prove shape, elasticity and brightness are maintained even after repeated cycles. These tests ensure a Splash swimsuit keeps its performance for entire seasons, unlike non-certified yarns that show wear after just a few uses.

• Certified resistance to marine salinity
• Color hold in the presence of chlorine
• Colorfastness under intense UV rays
• Shape and stretch retained after frequent washing
• No harmful substances for wet-skin contact

3. How to work with Splash: recommended stitches for perfect swimwear

Splash works best with crochet hook 3-3.5 or needles 4-5, sizes chosen to achieve compact, covering fabric without making it stiff. For swimwear, it’s crucial to create structures that are dense yet stretchy: single crochet and slip stitch are ideal for cups and the crotch area where you need extra coverage.

Lacy stitches like shells or arches are perfect for decorative details on sides and backs, taking advantage of the yarn’s natural elasticity to avoid rigidity. To ensure opacity even when wet, we always recommend making a swatch and soaking it before starting the full project.

The microfiber relaxes slightly on first wear in water: work with medium-high tension to compensate for this initial settling. For cups, many experienced makers use double-strand reinforcement or inner linings for extra support and coverage.

• Crochet hook 3-3.5: compact single crochet for structured areas
• Needles 4-5: ideal for stretchy, comfortable tops
• Wet swatch required to check transparency
• Medium-high tension to compensate for settling in water
• Reinforcements recommended for cups and support zones

4. Quick drying and moisture management: the microfiber advantage

Ultra-fast drying is a standout feature of Splash, thanks to the hydrophobic nature of polyamide microfiber. Unlike cotton or bamboo, which absorb and hold water for hours, polyamide repels water instead of soaking it up, drastically reducing drying time.

A Splash swimsuit stays lightweight even when wet, preventing the annoying sagging typical of absorbent yarns. Rapid moisture evaporation helps prevent mildew and odors, a common problem when swimwear stays damp too long, and lets you wear the garment again just a few hours after use.

This is especially valuable on vacation or for everyday pool use, when you need swimwear ready quickly. Quick drying also supports long-term durability by reducing the time fibers remain vulnerable to bacterial growth.

• Hydrophobic fiber that repels water instead of absorbing it
• Fully dries in a few hours even in the shade
• Minimal weight when wet, no sagging
• Helps prevent mildew and odors thanks to fast evaporation
• Ready to wear again quickly, ideal for travel

5. Color palette and dye-lot consistency guaranteed by Tessiland

Splash colors are specifically formulated to resist the elements that attack swimwear: salt, chlorine, sunscreens and UV rays. Dope-dyeing (solution dyeing), combined with the retroactive treatment, delivers superior colorfastness compared to surface-dyed yarns that fade quickly.

The range includes classic neutrals (black, white, beige) for elegant, versatile swimwear, bright summer shades (turquoise, fuchsia, coral) that stay vibrant season after season, and soft pastels for romantic styles. Each color keeps its intensity even after many swims in sea or pool.

Tessiland is the only e-commerce to show the dye lot/batch number directly on the product page. For projects that require multiple balls, this transparency ensures perfect color consistency, avoiding shade differences between lots. If a lot runs out, our customer service team—real people—will help you find the best solution.

• Dope-dyeing for superior colorfastness
• Certified resistance to salt, chlorine, UV and sunscreens
• Full range: classic neutrals, bright summer shades, soft pastels
• Dye lot number shown for guaranteed consistency
• Human support for out-of-stock lots

Care: How to keep your garments looking great over time

Proper care of Splash significantly extends the life of your swimwear, preserving stretch, shape and color brilliance over time. Follow these professional tips:

• Always rinse with cold fresh water immediately after use in the sea or pool to fully remove salt and chlorine that could damage the fibers
• Machine wash at max 40° on a delicate cycle, ideally placing the swimsuit in a protective laundry bag to avoid friction with other garments
• Use mild, neutral detergents with no bleach or harsh additives that could alter the properties of the polyamide microfiber
• Avoid high-speed spinning: gently squeeze by hand or use a short, low-spin cycle to preserve elasticity
• Dry flat in the shade to maintain the swimsuit’s original shape, avoiding clothespins that can leave permanent marks
• Do not iron: microfiber doesn’t need ironing, and excessive heat could compromise the certified elastic properties
• Avoid direct contact with oily sunscreens before they are fully absorbed into the skin, as they may leave stains
• Store swimwear completely dry and away from direct heat sources to preserve all technical fiber properties over time
