Product Description

30D Hard Cotton Fiber - Long Support Industrial Filling Textile Fiber

30D*64MM High Crimp Furniture Support Textile Raw Material

Product Overview

Our 30D*64MM rigid hard cotton polyester staple fiber is a professional heavy-denier high-support industrial filling fiber, specially developed for high-hardness anti-collapse rigid needle-punched hard cotton and furniture supporting nonwoven industry.

Different from common soft low-denier filling fiber, this 30D heavy denier fiber features rigid fiber body and superior bearing performance, serving as core raw material for high-support mattress, sofa base and automotive sound-insulation hard cotton.

Specifications can be customized

Core Advantages

30D Heavy Denier Ultra High Stiffness

Customized 30D heavy thick denier design provides superior hardness and supporting force compared to conventional 7D/15D fibers, eliminating soft collapse defects.

64mm Extra Long Fixed Cut Length

Standard 64mm extra-long industrial fixed length enhances interweaving cohesion, preventing fiber shedding and layer separation during production.

Permanent High Rebound & Anti-Collapse

High-density stereo mechanical crimp technology ensures 92% compression rebound rate with no permanent flattening or hollow sagging.

Virgin Raw Material Quality

Made from 100% new virgin polyester chips with anti-aging and mildew-proof additives for long-term durability.

Ultra Low Shrinkage Performance

High-temperature heat setting treatment maintains water shrinkage rate below 2.0%, ensuring dimensional stability.

Superior Processability

Compatible with all high-speed needle punching and thermal bonding nonwoven machines with low production waste.

Environmental & Safety Compliance

Odor-free, non-toxic production meets global home textile, automotive interior and furniture raw material standards.

Frequently Asked Questions

Q1: Why choose 30D heavy denier rigid fiber?

A1: 30D heavy denier provides ultra-high hardness and bearing support, significantly stronger than 7D/15D fibers, ideal for rigid support applications without soft sagging.

Q2: Will it collapse after long-time compression?

A2: Permanent 3D locked crimp structure with 92% high rebound rate prevents permanent flattening or collapse under long-term heavy pressure.

Q3: What is the advantage of 64mm extra long length?

A3: Longer fiber length enhances cross cohesion, resulting in tighter finished hard cotton with no fiber shedding or layered separation.

Q4: Is it virgin material or recycled material?

A4: 100% brand new virgin polyester chip material ensures stable performance with anti-yellowing and anti-aging properties.

Q5: Suitable for needle punched hard cotton machine?

A5: Fully compatible with all standard needle punching and thermal bonding nonwoven equipment for smooth mass production processing.

Q6: Is the fiber odorless and eco-friendly?

A6: Odor-free, non-toxic production with no chemical residues meets international home textile environmental export standards.

Q7: Can I get free test samples?

A7: Free small samples are available for stiffness testing and production line trial runs.
