The present invention relates to a polyester staple yarn for a wet non-woven fabric, and a wet non-woven fabric including the same, wherein the polyester staple yarn is manufactured by using a polymerization catalyst including a titanium-based compound. The polyester staple yarn is superb in terms of dispersibility due to the remarkably low defect formation thereof, and thus, the present invention can provide a wet non-woven fabric having excellent mechanical strength, and a manufacturing method therefor.

A stitchbonded washable towel made from a stitchbonded fabric having a cellulosic nonwoven sheet of cellulosic fibers, and an integrated nonwoven sheet of an outer sublayer of wood pulp fibers, and an inner layer of textile fibers substantially entangled with the wood pulp fibers, and confronting the cellulosic nonwoven sheet of cellulosic fibers. The stitchbonded fabric as uses a pattern of stitching yarns that fixes the cellulosic nonwoven sheet to the integrated nonwoven sheet. A post-treatment of the stitchbonded fabric in a heated aqueous solution containing soil release polymer gathers the fabric into the towel, and provides stain and soil re-deposition resistance.

A fabric made by the method of providing a non-woven batt having flame retardant fibers, stitch bonding the non-woven batt with an elastic yarn, and heat treatment the stitch bonded, non-woven batt. The stitch bonded non-woven batt is exposed to a temperature in a range of 65 C. to 200 C. for a period in a range of 30 seconds to 120 seconds, and contracts in the machine direction in a range of 5% to 65% and in the cross-direction in a range of 20% to 70%. In an embodiment, the fabric is adapted for use as a mattress core cover.

A cargo load restraint strip may have a base layer that comprises a stitchbond fabric. A separate reinforcement layer may comprise reinforcing strands or other type of material to increase tensile strength. An adhesive layer may be configured for attachment to a container wall and may include a release paper liner that may be peeled away prior to such attachment.

A washable fire-resistant fabric and a method for making a washable fire-resistant fabric comprises a lightweight pliant non-woven batt blended from two or more types of fire-resistant organic fibers which are non-irritating to human skin. A method for stitch bonding a pliant batt of intertwined fire-resistant fibers to form a fabric which is durable and resistant to unraveling is also provided. The fabric has fire-resistant properties wherein the fabric prevents the ignition of articles made therefrom when exposed to high heat or flame sources and further insulates a wearer of the clothing from high heat or flame sources to prevent serious burns.

The invention relates to a melt-processable fiber-bonding agent made of poly(vinylidene fluoride) (PVDF), such as KYNAR PVDF from Arkema, as well as to fibrous materials bonded with the PVDF fiber-bonding agent. The PVDF fiber-bonding agent is a low-melt temperature, low melt viscosity PVDF polymer or copolymer with excellent chemical and oxidative resistance properties, and is suitable for bonding fibers in non-woven fabrics, especially for use in chemically-aggressive environments. The PVDF fiber-bonding agent composition allows it to be processed into fibers on conventional melt spinning equipment. The PVDF fiber-bonding agent is introduced into non-woven fabric in the form of a continuous fiber web or as a component of a mixed fiber formulation. When heated above its melting point, the lower melting point PVDF fiber-bonding agent of the invention bonds the fibers of the fiber framework at the fiber cross-over points.

A cleaning pad structure of stitch bonded construction incorporating one or more substrate layers of an absorbent nonwoven material with an optional additional fluid blocking substrate layer of polymer film or other suitable material in juxtaposed relation to the absorbent nonwoven layers. Stitching yarns are introduced in stitching relation through the substrate layers. One face of the pad defines a cleaning surface of raised yarn loops formed by the stitched yarns. The pad further includes an attachment surface facing away from the cleaning surface. The stitches of yarns across the attachment surface define an engagement surface for attachment to cooperating hooking elements across a surface of a mop head to define a hook and loop attachment system.
