A blowable insulation material comprising natural fibers and short cut synthetic fibers or fiber balls. The natural fibers and short cut synthetic fibers or fiber balls are individually treated with a water repellent to impart water repellency to the fibers, and later aerodynamically blended together. The water repellent fibers constitute a part or most of the blowable insulation material, thus enhancing the durability of the structure as well as water repellency, which may be advantageous during washing or laundering.

The present invention relates to a flame-retardant nonwoven fabric for a mattress, and a flame-retardant nonwoven fabric for mattresses comprising flame-retardant rayon (FR-Rayon) staple fibers of 20 to 50% by weight; modacrylic staple fibers of 30 to 60% by weight; polyimide (PI) staple fibers of 10 to 30% by weight; and low melting polyester (LM PET) staple fibers of 5 to 20% by weight provides enhanced flame retarding and mechanical properties.

Disclosed herein are The invention relates to curled fiber mats. The invention further includes methods of making curled fiber mats, comprising forming a fibrous media from a fibrous material, treating the fibrous media with a crosslinking agent to form a treated fibrous media, and drying and/or curing the treated fibrous media to produce a curled fiber mat that has a permanent curl.

A novel nonwoven material for use as a cover of bedding and furniture is disclosed. The inventive method comprises creating a layered nonwoven material, cutting one or more desired shapes from a portion of said layered nonwoven material; securely attaching a first portion of said one or more desired shapes to a second portion of said one or more desired shapes to create a cover containing an internal cavity; and placing a furniture item within said internal cavity of said cover. The furniture item is selected from a group comprising a pillow, a cushion, a mattress, and a duvet.

Provided are a fibrous sheet having a stress relaxation rate defined by the following formula of less than or equal to 85%:

stress relaxation rate [%]=(stress S.sub.5 at extension after five minutes/stress S.sub.0 at initial extension)?100

when a stress at extension immediately after extension in an in-plane first direction at 50% elongation is defined as a stress S.sub.0 (N/50 mm) at initial extension, and a stress at extension at a time of extending in the first direction at 50% elongation for five minutes is defined as a stress S.sub.5 (N/50 mm) at extension after five minutes, and a bandage including the fibrous sheet.
