Detailed Product Description
The 3D*64MM hollow down-like polyester staple fiber solves key pain points of traditional filling materials. Ordinary solid polyester fill is heavy, low in fluffiness and poor in warmth-to-weight ratio, and easily flattens over time. Natural down, while soft and warm, comes with high cost, allergy risks, complicated care requirements and a tendency to clump after washing.
This baby soft hollow fiber offers an optimal balance of performance, comfort and value. Its 3D crimped hollow structure creates numerous tiny air chambers that lock in body heat, delivering thermal insulation comparable to down at a much lighter weight. The three-dimensional crimp design also gives the fiber outstanding resilience and loft retention.
The 3D fine denier specification creates an exceptionally soft, smooth hand feel that is gentle enough for baby products. The 64mm medium staple length is optimized for mainstream fiber processing and filling equipment, ensuring uniform opening and consistent filling density.
Manufactured from 100% virgin polyester under strict quality control, it is free of harmful additives and fluorescent substances. It is hypoallergenic, odor-free and suitable for skin-contact and infant applications.
Frequently Asked Questions
Is this real down? What is the difference from natural down?
No, it is a high-quality hollow polyester staple fiber designed to mimic the feel and warmth of natural down. Compared with natural down, it is hypoallergenic, more affordable, washable and easy to dry, with minimal clumping after laundering.
Will it clump or go flat after washing?
No. The 3D crimped hollow structure maintains good resilience and fluffiness after repeated washing. It dries quickly and recovers its loft fully, with far less clumping and matting than natural down or ordinary solid filling fibers.
Is it safe for baby products and skin contact?
Yes. It is made from 100% virgin polyester, free of fluorescent agents, harmful chemicals and unpleasant odors. It is hypoallergenic with a baby-soft smooth touch, meeting safety requirements for infant and skin-contact products.
What filling processes is it compatible with?
It is compatible with fiber opening, carding, blow filling and automatic filling machines. It can be used as loose fill, or processed into bonded wadding, non-glue wadding and other filling materials for different production needs.
Can it be blended with other fibers?
Yes. It can be blended with regular polyester, viscose, wool and other fibers in different proportions to adjust softness, warmth, weight and production cost according to product positioning.
Can we get samples for testing before bulk order?
Yes, samples are available for hand feel evaluation, fluffiness test, washability test and filling trial. Please contact us to request sample details.
What is the lead time for bulk orders?
Standard specifications are generally shipped within 3-7 working days for stock items. Custom specifications lead time is usually 7-15 working days after deposit confirmation, depending on order quantity.
