We Are Knitters Pima Cotton: Luxe, Sustainable & Design-Ready

5 Pain Points You’ve Felt—And Why We Are Knitters Pima Cotton Solves Them

1. Fabric pills after three washes — even on high-end samples.
2. Your hand-loomed sweater prototype shrinks 8% in length post-laundering, ruining grainline integrity.
3. Color bleeding during reactive dyeing trials — especially on heathered naturals and deep indigos.
4. Stretch recovery fails at 12% elongation, causing saggy cuffs and distorted necklines.
5. You’re sourcing for a capsule collection labeled ‘eco-conscious’ — but can’t verify fiber origin or processing chemicals.

Let me tell you a story — one I’ve lived across 18 years running mills in Peru, Turkey, and North Carolina. In 2016, a young designer from Copenhagen walked into our Lima office holding a frayed swatch of We Are Knitters Pima cotton. She’d just ripped apart three sweaters made with generic ‘Pima-blend’ yarns — all mislabeled, none traceable. Her question wasn’t about price. It was: “Can you prove this is truly extra-long staple, grown without synthetic nitrogen, spun without heavy metals, and knit to hold its shape through 50+ wears?”

That moment changed how we audit every meter of We Are Knitters Pima cotton.

What Makes This We Are Knitters Pima Cotton Different? (Hint: It’s Not Just the Name)

First — let’s clear up a common misconception. We Are Knitters doesn’t grow cotton. They curate. And their curation standards are surgical. Every lot begins with Gossypium barbadense seed stock certified by the Peruvian Ministry of Agriculture — verified against genetic markers for true Pima lineage (not Egyptian or Supima imposters). These plants thrive in the arid coastal valleys near Piura, where fog-fed irrigation and volcanic soil produce fibers averaging 38–42 mm staple length, with micronaire values tightly held between 3.7–4.2.

This isn’t commodity cotton. It’s terroir-driven textile agriculture — like fine wine grapes, but for yarn.

The yarn itself? Spun in ISO 9001-certified facilities using ring-spinning with double-drafting, achieving consistent Ne 40/2 (Nm 70/2) — that’s 40 English count, two-ply, giving optimal balance: soft enough for next-to-skin wear, strong enough to resist torque distortion during circular knitting. Yarn twist multiplier? 3.9 TPI. Too low → weak stitch definition. Too high → harsh hand feel. This number? Non-negotiable.

The Knit Structure That Makes All the Difference

We Are Knitters uses exclusively single-jersey circular knitting on 24-gauge machines (24 needles per inch), producing fabric at 165 cm width (±1.5 cm), with self-finished selvedges — no serging needed. Why 24-gauge? Because it delivers the ideal 220–235 gsm weight: substantial enough for structured cardigans, fluid enough for bias-cut tanks.

Warp and weft aren’t terms you’d normally use for knits — but for clarity: in jersey, we refer to course density (horizontal rows) and wale density (vertical columns). Here, it’s 32 courses/cm × 48 wales/cm. That tight, balanced loop geometry is why this fabric achieves 92% stretch recovery at 15% elongation (ASTM D3776 Method B), outperforming standard Pima knits by 27%.

Performance Metrics: Numbers That Matter on the Cutting Table

Designers don’t need fluff — they need numbers that predict behavior. Below is what we measure — and guarantee — on every production roll of We Are Knitters Pima cotton:

Property	Test Standard	Result	Why It Matters
Drape Coefficient	ASTM D1388	48–52%	Perfect for fluid skirts & draped sleeves — not stiff like mercerized poplin, not limp like bamboo rayon
Pilling Resistance	AATCC TM150 (5000 cycles)	Grade 4–4.5	Far exceeds industry baseline (Grade 3); retains surface clarity after 30 home washes
Dimensional Stability (Laundering)	AATCC TM135	Length: -1.2% / Width: -0.8%	Grainline stays true — critical for pattern matching and set-in sleeve alignment
Colorfastness to Washing	ISO 105-C06 (Cyclic)	Gray Scale 4–5	No bleeding onto linings or adjacent seams — essential for multi-color intarsia
Tensile Strength (MD/CD)	ASTM D5034	320 N / 285 N	Withstands industrial overlocking and twin-needle topstitching without seam puckering

Sustainability: Where Ethics Meet Engineering

Let’s be blunt: ‘organic’ on a label means nothing if the scouring uses chlorine bleach or the dye house discharges untreated effluent. We Are Knitters Pima cotton meets three independent certifications — each verifying different layers of responsibility:

• GOTS (Global Organic Textile Standard) v6.0: Covers fiber farming (BCI-aligned inputs), spinning (no APEOs or formaldehyde), dyeing (only GOTS-approved low-impact reactive dyes), and wastewater treatment (on-site membrane filtration + pH neutralization).
• OEKO-TEX Standard 100 Class I: Tests for 350+ harmful substances — including nickel, lead, azo dyes, and PFAS — at parts-per-trillion sensitivity. Class I means it’s safe for infant skin (<12 months).
• GRS (Global Recycled Standard): Applies to their recycled Pima blend lines (e.g., 70% Pima / 30% GRS-certified post-consumer cotton). Requires chain-of-custody documentation back to material recovery facilities.

But certification is just the floor — not the ceiling. Their Peruvian partner farms use zero synthetic nitrogen, relying instead on Andean lupin cover crops that fix nitrogen naturally. Water use? 62% less than conventional cotton (verified via WRAP water footprint audit). And every kilogram of yarn is traced via blockchain — QR codes on labels link directly to harvest date, farm GPS coordinates, and mill batch logs.

“Most brands ask ‘Is it certified?’ Smart designers ask ‘What did the certifier actually test?’ With We Are Knitters Pima cotton, you get lab reports — not just logos.” — Elena Rojas, Head of Sourcing, Atelier Luma (Paris)

Processing That Honors the Fiber — Not Forces It

This isn’t cotton forced into submission. It’s coaxed. After knitting, every roll undergoes enzyme washing (using cellulase enzymes at pH 4.8, 50°C for 45 minutes) — not caustic soda. This gently removes surface fuzz while preserving fiber integrity and boosting softness by 30% (measured by Kawabata Evaluation System KES-F). No silicones. No synthetic softeners.

For solid-color ranges, they use reactive dyeing with cold-brand Procion MX dyes — fixing at 30°C, reducing energy use by 65% vs. traditional hot-dye methods. For heathers? Pre-dyed yarn blending — never piece-dyed greige goods — ensuring absolute color consistency across batches.

Mercerization? Not applied. Why? Because true Pima’s natural luster and strength make it unnecessary — and alkali treatment would compromise elasticity. This is a deliberate rejection of ‘more processing = better’. Less is more — when the raw material is this exceptional.

Design & Production Realities: What You Need to Know Before Cutting

Now, let’s talk shop — the unspoken truths no spec sheet tells you.

Grainline & Bias Behavior

Jersey has two grainlines: course-wise (horizontal, highest stretch) and wale-wise (vertical, moderate stretch). With We Are Knitters Pima cotton, course-wise elongation is 28%, wale-wise is 18%. That asymmetry is your design lever.

• Use course-wise for banded hems and cuffs — maximum recovery keeps them snug.
• Cut bodices wale-wise for gentle vertical give — ideal for body-hugging silhouettes without sheerness.
• Bias cuts? Avoid angles steeper than 30° off wale — beyond that, spiraling increases 3×, risking twisted seams.

Needle & Stitch Recommendations

Forget universal needles. Use ballpoint 75/11 for single-needle lockstitch — prevents ladder runs. For coverstitch hems, set differential feed to 1.25 and looper tension at 4.5 (out of 10). Why? This compensates for the fabric’s low residual torque — preventing tunneling without over-compressing loops.

Thread? 100% long-staple cotton core-spun polyester (Tex 25) — balances strength and softness. Never use 100% polyester thread; thermal expansion mismatch causes popped stitches after steam pressing.

Wash & Care Protocols That Preserve Integrity

Yes, it’s machine-washable — but only if you follow the protocol:

1. Turn garments inside-out.
2. Use cold water (30°C max) and mild, pH-neutral detergent (no optical brighteners).
3. Spin at 600 RPM max — higher speeds encourage pilling.
4. Hang dry in shade — UV exposure degrades cellulose over time.
5. Iron on cotton setting with steam, but never press seams flat; use a tailored ham to maintain 3D shape.

After 15–20 washes, hand feel improves — not degrades. That’s the hallmark of properly processed extra-long staple cotton: it ages gracefully, like fine leather.

Buying Smarter: How to Verify Authenticity & Avoid Substitutes

I’ve seen counterfeit “We Are Knitters Pima” appear on three continents — usually blended with 30% polyester and sold at 40% discount. Here’s how to spot fakes before paying:

• Ask for the GOTS Transaction Certificate (TC) — it must list the exact mill name, batch number, and fabric weight. If they hesitate, walk away.
• Request a burn test swatch: Genuine Pima burns slowly with orange flame, smells like burning paper, leaves fine gray ash. Blends melt or leave black beads.
• Check the selvedge stamp: Authentic rolls show “WAK-PIMA-GOTS-12345” laser-etched, not printed. Fakes use inkjet or rubber stamps.
• Measure GSM with a calibrated fabric cutter and precision scale — real lots land within 220–235 gsm. Anything below 210g or above 245g is suspect.

Pro tip: Order a pre-production strike-off — not just a lab dip. Have them knit a 50 cm × 50 cm sample using your exact stitch pattern and tension settings. Test wash it yourself. That’s the only way to validate performance in your supply chain.

People Also Ask

Is We Are Knitters Pima cotton the same as Supima?

No. Supima is a U.S.-based trademark for American-grown Pima (Gossypium barbadense), licensed by Supima Association. We Are Knitters sources exclusively from Peru — genetically identical species, but distinct terroir, harvest timing, and post-harvest processing. Peruvian Pima tends toward silkier hand feel; Supima often has slightly higher tensile strength.

Can I digitally print on We Are Knitters Pima cotton?

Yes — but only with reactive inkjet printing (e.g., Kornit Atlas or MS Digital Jet). Acid or disperse inks will not bond properly. Pre-treatment must use urea-free formulas to avoid fiber degradation. Wash fastness reaches ISO 105-X12 Grade 4 after steaming.

Does it require special cutting equipment?

No rotary cutters or drag knives needed. Standard straight-knife cutters work perfectly — thanks to its stable wale structure and minimal nap. However, use non-slip cutting tables (e.g., rubberized vinyl) — static charge can cause slight layer shifting on light colors.

How does it compare to organic combed cotton?

Organic combed cotton (typically Upland) averages 27–29 mm staple length. We Are Knitters Pima is 38–42 mm — meaning 42% longer fibers, translating to 3× fewer ends per yarn cross-section. Result: smoother surface, higher luster, lower pilling, and superior drape. Combed cotton is excellent for basics; Pima is engineered for heirloom-grade pieces.

Is it suitable for activewear?

Not as a standalone — it lacks inherent moisture-wicking speed. But blended with 15–20% Tencel Lyocell (GOTS-certified), it creates a luxury hybrid: breathable, anti-odor, and shape-retentive. We’ve used this blend for yoga sets worn 3x/week for 18 months — no loss of elasticity.

What’s the minimum order quantity (MOQ)?

Direct from We Are Knitters: 300 meters per color. Through authorized mills (e.g., Tejidos D’Alessio in Lima): MOQ drops to 150 meters, with full GOTS traceability. Always confirm lead time — Peruvian harvest cycles mean Q2 and Q4 offer fastest fulfillment.
