An absorbent article having a topsheet; an absorbent core; and a secondary topsheet positioned between the topsheet and the absorbent core is described. The secondary topsheet has a basis weight of about 35 grams per square meter (gsm) to about 65 gsm, and a hydroentangled fibrous structure having a machine direction (MD) bending stiffness of 0.2 mN.Math.cm to 12 mN.Math.cm according to EDANA Test Method WSP 090.5, and a substantially homogenous blend of fibers. The blend of fibers has a first fibrous component, a second fibrous component, and a third fibrous component, wherein the first fibrous component includes cellulose fibers of from between about 1.3 to 7.0 dtex; wherein the second fibrous component has a second dtex, wherein the third fibrous component comprises a third dtex which is smaller than the second dtex.

Provided herein are laminates including a flame retardant needle punch nonwoven along with methods of making and using the same. In some embodiments, the laminate comprises a first nonwoven fabric layer that is a spun bond nonwoven layer comprising polypropylene fibers; a second nonwoven fabric layer that is a needle punch nonwoven layer comprising a flame retardant; and an adhesive, wherein the adhesive adheres the first and second nonwoven fabric layers together. The laminate may be used as a filler cloth and/or in manufacturing mattresses.

A non-flip mattress with top side and bottom side and depending edges; wherein the bottom side is covered with a flame-resistant, highly needled, double-sided-calendered, needlepunch nonwoven fabric that passes 16 CFR 1633. The nonwoven fabric is a double-calendered, 80/20 flame-resistant rayon/polyester blend needled with a minimum of 190 punches per cm.sup.2 and with increased tensile strength.

Provided is a method for producing a semi-product for automobile equipment, the semi-processed product being moldable in a relatively broad range of heating temperatures and being capable of obtaining a final product with high stiffness. In the method for producing a semi-processed product for automobile equipment, needle punching is performed on a fiber web in which core-sheath composite fibers are accumulated, and the core-sheath composite fibers are three-dimensionally interlaced together. The core portion of the core-sheath composite fibers comprises a copolymer of ethylene glycol and terephthalic acid. The sheath portion of the core-sheath composition fibers comprises a copolymer including ethylene glycol, adipic acid and terephthalic acid. The weight ratio of core portion to sheath portion in the core-sheath composite fibers is 1 to 3:1. The core portion and the sheath portion are disposed concentrically. In the fiber web, the core-sheath composite fibers are bonded together by softening or melting the sheath portion.

To provide a process for producing a needle-punched nonwoven fabric with which, when finished by embossing, it is possible to obtain a hardly fluffing and distinct rugged pattern. [Solution] Sheath-core composite fibers are accumulated and a fibrous web is formed. The core component of the sheath-core composite fiber is formed from a copolymer of ethylene glycol and terephthalic acid. The sheath component is formed from a copolymer of ethylene glycol, adipic acid, terephthalic acid, isophthalic acid and diethylene glycol. The sheath-core composite fibers are three dimensionally interlaced with each other by needle-punching the web, to obtain the needle-punched nonwoven fabric. The needle-punched nonwoven fabric is passed through heated embossed roll to provide a rugged pattern on a surface. During the process, the sheath component are softening melted and melt bonded between the sheath-core composite fibers to obtain an embossed nonwoven fabric having a distinct rugged pattern.
