Definition and Name Origin

Pineapple Grid Fabric refers to a textile with a surface pattern resembling a pineapple grid, often featuring a porous, honeycomb-like texture. This unique surface design gives it high visual recognition, which is the origin of its name.

Material and Composition

• Natural Fiber Material: Made from pineapple leaf fibers, this type of fabric is environmentally friendly and sustainable. Fiber diameters range from 15–25 μm, with lengths between 30–45 mm.

• Chemical Fiber Material: Common variants include polyester knit pineapple grid fabric, such as 98% polyester and 2% spandex blends, offering both strength and elasticity. 100% polyester versions provide excellent durability and tensile strength.

• Blended Material: Silk-cotton or pure cotton blends combine the advantages of softness, breathability, and moisture-wicking properties, enhancing comfort for apparel use.

Key Properties

• Physical Performance: Air permeability ranges from 180–220 mm/s; moisture vapor transmission rate reaches 8,000–10,000 g/m²/24h. Drape coefficient is 0.25–0.35. Wrinkle recovery angles: 280–320° in warp, 260–300° in weft, demonstrating excellent drape and wrinkle resistance.

• Durability: After 50 standard wash cycles, the fabric retains over 85% tensile strength and maintains colorfastness at level 4, showing excellent long-term usability.

• Safety: Free from formaldehyde, heavy metals, and azo dyes; compliant with OEKO-TEX Standard 100 for eco-friendly textile safety.

• Additional Properties: Some variants are highly moisture-resistant, UV-resistant, soft to the touch, and suitable for embossing, printing, or surface finishing.

Production Process

• Fiber Extraction: Combines enzymatic hydrolysis with mechanical separation to preserve fiber integrity, achieving an extraction yield of 85.6%.

• Weaving Technology: Uses high-precision looms with specialized warp-weft interlacing to create the distinctive grid-like pattern.

• Dyeing Process: Combines natural plant dyes with eco-friendly reactive dyes, achieving colorfastness at levels 4–5.

• Finishing: Plasma treatment and nano-coating enhance UV resistance, achieving UPF 50+ protection.

Applications

• Apparel: Ideal for summer clothing, sportswear, underwear, base layers, loungewear, and sleepwear due to breathability and moisture-wicking properties.

• Home Textiles: Excellent drape and wrinkle resistance make it suitable for curtains, bedding, sofa covers, and other interior fabrics.

• Other Uses: Can be used in industrial textiles, such as filters or packaging; also suitable for shoe fabrics, automotive interiors, and handicrafts.

Care Instructions

Pineapple grid fabric is easy to maintain. It can be machine or hand washed. Avoid sharp objects that may scratch or damage the texture. After washing, lay flat to dry and avoid direct sunlight to preserve color and performance.
