Described is a composite made from a woven fabric, a non-woven fabric, or a knitted face fabric and a non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric is needle punched such that fibers protrude into the non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric has a first polymer having a first melting point and a second polymer having a second melting point being higher than the first melting point. The nonwoven backing material comprises a third polymer having a third melting point and a fourth polymer having a fourth melting point being higher than the third melting point. The woven fabric, the non-woven fabric, or the knitted face fabric is further bonded to the nonwoven backing material applying heat to at least partially melt or soften the first polymer and the third polymer such that they bond together.

Low linting imaged hydroentangled nonwoven composite

Hydroentangled composites having a wide variety of uses (e.g., personal hygiene articles, facers for fenestration absorbent patches on surgical drapes, facers on absorbent surgical drapes, etc.) are provided. The hydroentangled composite includes at least two nonwoven webs hydroentangled together. The hydroentangled composite may have a three-dimensional structure. Additionally, the at least two nonwoven webs may have different bonding levels and/or lint levels.

Process for producing needle-punched nonwoven fabric

[Problem] 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.

NONWOVEN WEB WITH HIGHLY DETAILED AND FUNCTIONALLY ADVANTAGEOUS BOND PATTERN
20210363676 · 2021-11-25 ·

A nonwoven web having an advantageous bond pattern impressed by a bonding pattern on a roller is disclosed. The bonding pattern is selected to have a bonding area percentage from 6 to 14 percent, which provides a desirable level of bonding of filaments and/or fibers for mechanical strength, while retaining desirable pliability and/or liquid handling characteristics. The bonding area is also relatively highly dispersed, which provides for a relatively greater number of bonded areas for the selected bonding area percentage. The greater number of bonded areas is believed to provide improved structural integrity while still retaining pliability and/or liquid handling characteristics, and also provide for enhanced visual detail and complexity. The relatively highly dispersed bonding area is believed to be particularly effective for nonwoven web materials having three or more layers, with outer layers of polymeric filaments, and even more particularly, one or two outer layers of fine filaments.
