ProSoft Bamboo Loop Terry ECO-PUL: The Complete Guide to Wazoodle's Absorbent Bamboo Waterproof Fabric

What ProSoft Bamboo Loop Terry ECO-PUL Is and Why It Matters

ProSoft Bamboo Loop Terry ECO-PUL is a dual-sided waterproof laminate that bonds 1 mil polyurethane film to bamboo-blend loop terry using ECO-Thermal Bonding Technology (permanent film fusion independently tested 50% stronger than competitor US-made PUL). At 270–300 GSM with a waterproof barrier rated at more than 100× any normal use pressure and breathability matched to resting body moisture output, this is the fast-absorbing member of the bamboo PUL family — built around raised loop terry construction that captures liquid through capillary action rather than the brushed pile softness of Bamboo Fleece ECO-PUL.

The defining feature is the loop terry face: raised yarn loops create three-dimensional channels that pull liquid in on contact — the same construction used in traditional bath towels, applied here with integrated waterproof backing. Where ProSoft Bamboo Fleece ECO-PUL prioritizes plush softness, Loop Terry ECO-PUL prioritizes speed of liquid capture.

Customers describe the bamboo terry side as "exceptionally soft" and "gentle on sensitive skin" while noting the 0.030" profile is thin enough to be "unnoticeable when worn." ProSoft Bamboo Loop Terry ECO-PUL features Waterproof 300X Technology (300+ wash cycle durability) and SilentFlex Technology (quiet fabric-like drape). CPSIA certified, Forever Chemicals-Free (no PFAS, BPA, phthalates). Made in USA by AKAS Tex.

The Complete ProSoft Bamboo Loop Terry ECO-PUL Lineup: V1, V2, and FoodSAFE Variants

ProSoft Bamboo Loop Terry ECO-PUL comes in three variants sharing the same loop terry base and PUL waterproof backing, separated by wash temperature tolerance and food-contact certification.

V1 — Original Formula
  • W-546 — V1 ProSoft Bamboo Loop Terry Waterproof ECO-PUL Fabric: 300 GSM, 60" width, 0.030" thickness. 43% bamboo viscose / 24% polyurethane / 18% organic cotton / 15% polyester loop terry with ECO-Thermal Bonding Technology (permanent film fusion independently tested 50% stronger than competitor US-made PUL) and Waterproof 300X Technology. 5% crosswise stretch, minimal lengthwise stretch. UPF 50+ UV protection. Warm water washing only — temperatures above 140°F accelerate polyurethane degradation. The most customer-validated variant with extensive real-world performance data. Available in Natural colorway.
V2 — Current Formula
  • W-384 — V2 ProSoft Bamboo Loop Terry Waterproof ECO-PUL Fabric: 300 GSM, 60" width, 0.030" thickness. Same fiber blend and dimensions as V1 with improved hot-water wash tolerance — hot water washing maintains laminate integrity where V1 requires warm-only washing. Same waterproof and breathability performance. Choose V2 for hygiene-critical applications requiring regular hot-water sanitation. Available in Natural colorway.
FoodSAFE
  • W-686 — ProSoft FoodSAFE Bamboo Loop Terry Waterproof PUL Fabric: 270 GSM, 60" width, 0.030" thickness. Same fiber blend with FDA food-contact certification (21 CFR 175.300 and 177.1680 — certified for direct contact with all food types from freezer storage at -20°C to 250°F). Both fabric and film sides tested safe. The only bamboo-based PUL certified for direct food contact. Slightly lighter construction than V1 and V2. Available in Natural colorway.
V1 vs V2 — The Key Difference Is Wash Temperature: V1 and V2 share the same dimensions, weight, and waterproof performance. The critical difference is that V2's laminate tolerates hot water washing while V1 is limited to warm water (under 140°F). For cloth diapers, incontinence products, and any application requiring regular hot-water sanitation, V2 is the recommended choice.

All fabric specifications may vary ±10% due to textile industry manufacturing standards.


Choosing Your ProSoft Bamboo Loop Terry ECO-PUL: V1 vs V2 vs FoodSAFE

All three variants share the same waterproof barrier, breathability, and 300+ wash durability. Your choice depends on wash temperature requirements and whether FDA food-contact certification is needed.

When V1 (W-546) Is the Right Choice
  • Baby bibs and burp cloths: Customer-validated as waterproof backing — loop terry captures drool and spit-up while PUL prevents strike-through to clothing.
  • Nursing pads: Multiple makers validate this for nursing pad construction where the thin 0.030" profile keeps pads discreet under clothing.
  • Bra liners for hot weather: Customer-discovered application — bamboo terry against skin manages perspiration while the waterproof layer prevents moisture from transferring to outer garments. Users report the fabric is thin enough to be "unnoticeable when worn."
  • Cloth menstrual pads: Customer-validated for reusable period products where loop terry provides fast liquid capture and PUL prevents leakage.
When V2 (W-384) Is the Right Choice
  • All-in-one cloth diapers: Combines absorbent terry with waterproof backing in a single layer — simplifies construction versus separate absorbent and barrier fabrics. V2's hot-water tolerance supports the frequent sanitation diapers require.
  • Changing table pads and burp cloths: Customer-validated for baby care items requiring regular hot-water laundering.
  • Incontinence products and mattress protectors: Hot-water washing capability supports the hygiene standards required for these applications.
When FoodSAFE (W-686) Is the Right Choice
  • Reusable food storage: Food storage bags, bowl covers, snack pouches, and lunch bag linings requiring FDA food-contact certification from freezer (-20°C) to 250°F. The loop terry interior wicks condensation away from food while PUL creates a waterproof seal.
  • Baby bibs and feeding accessories: CPSIA certified + FDA food-contact safe for infant feeding products requiring both waterproofing and chemical safety.
  • Cloth diapers: Customer-validated for diaper construction — slightly lighter weight (270 GSM) reduces bulk in layered builds.

Care difference between V1 and V2: V1 requires warm water washing only (under 140°F) — hot water accelerates polyurethane degradation. V2 tolerates hot water washing. If your application requires regular hot-water sanitation, choose V2 or FoodSAFE.

Working With ProSoft Bamboo Loop Terry ECO-PUL: Sewing and Construction Guide

ProSoft Bamboo Loop Terry ECO-PUL requires more attention during sewing than flat-face PUL fabrics. The raised loop structure can snag on feed dogs, presser feet, and rough surfaces — customers report the fabric is "challenging to stitch through initially, requiring practice."

The fabric arrives cut-and-sew ready with no pre-washing required (do NOT pre-wash — pre-washing risks wringing damage to the laminate bond).

Cutting and Layout
  • Sharp cutting tools: Use a sharp rotary cutter or shears to cut cleanly through loops without snagging — dull blades catch loop yarns and create ragged edges.
  • Mark on terry side only: The PUL film side is difficult to mark cleanly. Use washable markers on the loop terry face.
  • Pattern weights over pins: Minimize pinning — every needle hole compromises waterproofing. Use pattern weights where possible during layout.
Sewing Recommendations
  • Needles: Ballpoint needles (size 90/14) for the knit base — sharp needles slice yarns and create holes that leak.
  • Presser foot: Walking foot is essential — prevents loop layers from shifting and manages PUL film friction. Teflon/glide foot is an alternative. Reduce presser foot pressure to avoid flattening loops.
  • Thread: Quality polyester thread (Tex-27 or 65/2 grade) exclusively — cotton and rayon wick moisture through needle holes.
  • Stitch length: 3.0–3.5mm reduces perforation density and helps preserve waterproof integrity.
  • Go slowly: Loop snagging is the primary sewing challenge. Feed fabric through the machine at a controlled pace to prevent loops catching on feed dogs.

Critical — Seam Sealing Required: Every needle hole through the polyurethane film permanently compromises waterproofing. Apply heat-activated seam sealing tape over all sewn seams to restore the waterproof barrier.


Pairing ProSoft Bamboo Loop Terry ECO-PUL With Other Wazoodle Fabrics

ProSoft Bamboo Loop Terry ECO-PUL shares the same dual-sided advantage as Bamboo Fleece ECO-PUL: the loop terry face absorbs liquid while the PUL reverse prevents strike-through. The loop terry construction captures liquid faster than brushed fleece — making this the preferred backing when speed of absorption matters.

Absorbent Core Partners
  • Zorb Original (W-202): High-capacity absorbent interlining for builds where the loop terry's built-in absorbency is insufficient. Zorb core adds capacity while the PUL backing provides the waterproof barrier.
  • Zorb 3D Organic Cotton Dimple (W-231): Standalone organic absorbent for heavy-capacity builds — overnight diapers and heavy-flow pads where maximum liquid holding is needed above the Loop Terry ECO-PUL backing.
  • ProECO Bamboo Loop Terry (W-545): Additional unlaminated loop terry layers for extra absorbency — stack as inner core with the ECO-PUL variant as the waterproof outer.
Proven Layer Stack Configurations
  • Skin-Contact Top → Zorb Core → ProSoft Bamboo Loop Terry ECO-PUL (backing): Multi-layer pad construction where the loop terry face provides additional absorbency beneath the Zorb core while PUL creates the final waterproof barrier.
  • ProSoft Bamboo Loop Terry ECO-PUL as standalone single-layer: For bibs, burp cloths, bra liners, and changing pads where moderate absorbency plus waterproofing in a single fabric is sufficient.

Your results may vary based on product design, construction method, and end-use requirements.

Common Applications for ProSoft Bamboo Loop Terry ECO-PUL

ProSoft Bamboo Loop Terry ECO-PUL serves applications where fast liquid capture plus waterproof backing eliminates the need for separate absorbent and barrier layers. The 0.030" thin profile keeps finished products discreet, and small businesses have validated this fabric for commercial product line development.

Baby bibs and burp cloths are the dominant application. Loop terry face captures drool and spit-up on contact while PUL backing prevents strike-through to clothing. Customer-validated as waterproof backing that "works well" for these products.

Nursing pads benefit from loop terry's fast liquid capture combined with the thin 0.030" profile that keeps pads discreet under clothing. Multiple makers validate this application.

Bra liners and sweat management are customer-discovered applications for hot weather. Bamboo terry against skin absorbs perspiration while the waterproof layer prevents moisture from transferring to outer garments. Also validated for underarm sweat-protection gussets sewn into lightweight undergarments — thin enough to remain "unnoticeable when worn."

All-in-one cloth diapers use V2 (W-384), which combines absorbent terry with waterproof backing in a single layer, simplifying construction versus separate absorbent and barrier fabrics. FoodSAFE (W-686) also customer-validated for diaper construction.

Cloth menstrual pads use loop terry for fast liquid capture while PUL prevents leakage — customer-validated for handmade reusable period products.

Reusable food storage uses the FoodSAFE variant (W-686) for food storage bags, bowl covers, and lunch bag linings with FDA certification. Loop terry interior wicks condensation away from stored food.

Changing pads and mattress protectors provide an absorbent surface that captures spills while waterproof backing protects the surface underneath. V2's hot-water tolerance supports frequent sanitation.

ProSoft Bamboo Loop Terry ECO-PUL Care: Washing, Drying, and What to Avoid

ProSoft Bamboo Loop Terry ECO-PUL maintains its Waterproof 300X Technology (300+ wash cycle durability) when care protocols protect the polyurethane film from chemical degradation and heat damage. The fabric arrives cut-and-sew ready — do not pre-wash before construction.

Washing

Wash temperature depends on variant: V1 (W-546) — wash warm only, under 140°F. Hot water accelerates polyurethane degradation. V2 (W-384) — hot water washing is safe. FoodSAFE (W-686) — wash hot (145–165°F) with zero-residue liquid detergent.

Add an extra rinse cycle to remove detergent residues that accumulate on the polyurethane film.

Drying

Dry on medium heat only — never exceed 130°F (50°C). Warm iron on the terry side only if needed — never iron the PUL film directly.

What to Avoid

Substances that permanently destroy waterproofing: Fabric softeners coat fibers, destroying both waterproofing and loop terry absorbency — damage is irreversible. Chlorine bleach causes delamination. Vinegar and baking soda break down the laminate bond. Non-chlorine oxygen bleach is acceptable sparingly.

Manufacturing Odor

New fabric may have a noticeable chemical smell from the high-temperature thermal bonding process. This dissipates after a single wash-dry cycle, or allow 1 day to 2 weeks of airing.
