Industrial Applications
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. |
