The present disclosure provides an apparatus that includes a fiber gun. In an embodiment, the apparatus may controllably cut one or more fibers into one or more fiber segments. In an embodiment, the apparatus may controllably shape one or more fibers into different shapes (e.g., from loops into substantially straight fibers). In an embodiment, the apparatus may controllably position the one or more fiber segments onto a supporting member (e.g., a composite component). For example, the apparatus may include a robot that may controllably move the fiber gun relative to a supporting member and align the fiber gun such that the one or more fiber segments are controllably positioned on the supporting member. The apparatus may further include a controller that at least partially controls operation of the apparatus.

An absorbent material, such as a non-woven web or a tissue paper, includes continuous filaments and short fibers, the short fibers including natural and/or synthetic fibers or staple fibers. The absorbent material exhibits an absorbency speed of equal to or less than 2 s and a weight loss when washed of equal to or less than 5%. The absorbent material can be incorporated into a wipe.

An abrasion resistant wipe and a manufacturing method therefor. The abrasion resistant wipe has an upper layer and a lower layer each being a meltblown fiber web and a middle layer being wood pulp fiber web; wherein the meltblown fiber web comprises meltblown fibers with fiber surface being high melting point resin and meltblown fibers with fiber surface comprising low melting point resin; there is a difference of ≥20° C. between melting point of the low melting point resin and melting point of the high melting point resin; percentage of the meltblown fibers with fiber surface comprising low melting point resin in total fibers of the meltblown fiber web is greater than 5%; the meltblown fibers of the meltblown fiber web penetrate in the wood pulp fiber web.

Disclosed are, inter alia, a sound absorption and insulation material including a polyester hollow fiber, a polyester low-melting-point composite fiber and a polyester base fiber, a sound absorption and insulation pad for a floor including the same, and a manufacturing method thereof for improving the elasticity and sound absorption and insulation performance of the sound absorption and insulation material. The sound absorption and insulation material is an environmentally friendly material that can reduce discomfort due to the generation of volatile organic compounds (VOCs) and the emission of toxic gases during combustion. Also, the sound absorption and insulation pad including the sound absorption and insulation material can exhibit superior sound absorption performance, sound insulation performance and actual vehicle performance compared to a conventional sound absorption and insulation pad of the same thickness.

Provided are a water-absorbing wipe and a manufacturing method therefor. The water-absorbing wipe has upper and lower layers of melt-blown fiber webs, and an intermediate layer of a wood pulp fiber web containing a super absorbent resin, wherein melt-blown fibers of the melt-blown fiber webs are woven into the wood pulp fiber web. The super absorbent resin in the water-absorbing wipe can rapidly absorb water or detergent. During wiping, by virtue of the liquid retention ability of the super absorbent resin, the water or the detergent is slowly released to the surface of an object to be cleaned, such that stains can be rapidly removed due to the wetness of the wipe. Moreover, after absorbing a large amount of water or detergent, the wipe can keep the surface dry without leaving behind drops of liquid, and is more suitable for use when the wipe is wet.

Dimensionally-stable fibrous structures including ceramic-coated melt-blown nonwoven fibers made of a flame-retarding polymer and processes for producing such fire-resistant nonwoven fibrous structures. The melt-blown fibers include poly(phenylene sulfide) in an amount sufficient for the nonwoven fibrous structures to pass one or more fire-resistance test, e.g. UL 94 V0, FAR 25.853 (a), FAR 25.856 (a), and CA Title 19, without any halogenated flame-retardant additive, and have a ceramic coating. The melt-blown fibers are subjected to a controlled in-flight heat treatment at a temperature below a melting temperature of the poly(phenylene sulfide) immediately upon exiting from at least one orifice of a melt-blowing die, in order to impart dimensional stability to the fibers. The nonwoven fibrous structures including the in-flight heat-treated melt-blown fibers exhibit a Shrinkage less than a Shrinkage measured on a nonwoven fibrous structure including only fibers not subjected to the controlled in-flight heat treatment operation, generally less than 15%.
