Product Description
Shu Elastic Fiber 3.6D*88MM Plant-Based Soft Durable Shape Retention Down-Like Filling Fiber
Product Overview
Our 3.6D*88MM bio-based stretch elastic staple fiber (brand: SUSTENS®) is a high-performance multifunctional fiber made from DuPont Sorona® bio-based PTT polymer through advanced spinning and crimping technology. It integrates three core advantages: sustainable environmental protection, super high resilience and soft comfort, and is an ideal upgraded material to replace ordinary polyester filling, low-grade down and spandex in some fields.
Different from ordinary polyester filling which relies on mechanical crimp to obtain bulkiness, the elasticity of this fiber comes from the inherent spring-like molecular structure of PTT and natural 3D spiral crimp. It has excellent elastic recovery performance, can quickly rebound after heavy compression, and maintains fluffy state for a long time without collapse and hardening.
The 3.6D medium denier and 88mm long length are golden specifications specially designed for filling and nonwoven processing. Longer fiber length brings better fiber cohesion and more stable three-dimensional network structure, which effectively improves the windproof and thermal insulation performance of finished wadding.

Core Advantages
Bio-Based Sorona® Polymer, Sustainable & Low-Carbon Eco-Friendly
This stretch elastic staple fiber is produced from DuPont Sorona® bio-based PTT polymer, with 37% of its molecular carbon derived from annually renewable plant resources through bio-fermentation technology. Compared with traditional petroleum-based polyester and nylon, its production process reduces energy consumption by about 40% and greenhouse gas emission by about 20%.
Natural 3D Spiral Crimp Structure, Ultra-High Resilience & Long-Lasting Shape Retention
Benefiting from the unique Z-shaped spring-like molecular chain of PTT and the 3D spiral crimp forming process, the fiber presents a natural three-dimensional spring structure with outstanding elastic resilience. It achieves over 90% recovery after 300% elongation, with compression set below 5% after long-term compression.
Down-Like Soft Fluffy Hand Feel, Skin-Friendly Hypoallergenic
The 3.6D medium denier design balances bulkiness and softness perfectly. With smooth fiber surface and delicate touch, it presents soft, light and fluffy down-like hand feel, getting rid of the stiff and heavy feeling of ordinary polyester filling.
88mm Long Length, Excellent Processing Adaptability for Filling & Nonwoven
The 88mm long cut length is specially optimized for filling, spray bonded cotton and needle-punched nonwoven processes. Longer fiber length brings better inter-fiber cohesion and entanglement, forming a more stable three-dimensional fluffy structure.
Washable & Durable, No Clumping No Deformation After Repeated Washing
Different from ordinary polyester filling which easily clumps and hardens after washing, this bio-based PTT fiber has excellent washing resistance. It supports machine washing and tumble drying, and remains fluffy and dispersive after repeated washing.

Frequently Asked Questions
Q1: What is the raw material of this stretch elastic fiber? Is it eco-friendly?
A1: It is made from DuPont Sorona® bio-based PTT polymer, with 37% bio-carbon from renewable plant resources. Production reduces energy use by ~40% and carbon emission by ~20% vs. petroleum-based fiber, fully compliant with global sustainable standards.
Q2: How is the resilience compared with ordinary polyester filling?
A2: It has natural 3D spiral spring structure with over 90% recovery after 300% elongation. It does not collapse or harden after long-term compression, with resilience and service life 2-3 times that of ordinary polyester filling.
Q3: Will it clump or deform after washing?
A3: No. It has excellent washing resistance. After repeated machine washing and tumble drying, it remains fluffy and dispersed, no clumping, no caking, no elasticity loss, maintaining stable thermal insulation performance.
Q4: Is 88mm length suitable for spray bonded cotton and carding wadding lines?
A4: 88mm long length is specially optimized for filling and wadding processing. It brings better fiber cohesion and stable 3D structure, fully compatible with all mainstream carding, web forming and wadding production lines.
Q5: Is it safe for infants and sensitive skin?
A5: Yes. It is hypoallergenic, odorless, mildew resistant and does not breed mites, non-irritating to sensitive skin and infants, serving as a healthy and safe down alternative filling material.
Q6: Can this fiber be used for spinning besides filling?
A6: Yes. It can be used to produce coarse count elastic blended yarn, dyed at 100°C atmospheric pressure, with bright color and good color fastness, suitable for denim, casual wear and home wear fabrics.
Q7: Can I get free samples for resilience and washing test?
A7: Small test samples are provided free of charge for resilience test, washing resistance test and production line trial verification.
