Melt-blown fiber web having improved elasticity and cohesion, and manufacturing method therefor

The present invention relates to a melt-blown fiber web having improved elasticity and cohesion, and a manufacturing method therefor. The objective of the present invention is accomplished by a melt-blown fiber web comprising a thermoplastic resin which comprises 10 to 60 wt % of thermoplastic resin microfibers and 40 to 90 wt % of non-circular cross-sectional hollow conjugated staple fibers with respect to the total weight of the fiber web.

CELLULOSE ACETATE FIBER BLENDS FOR THERMAL INSULATION BATTING

A fiber blend comprising a staple fiber formed from cellulose acetate and a binder fiber. The staple fiber has a crimp frequency of 10 to 30 crimps per inch (CPI), a cut length of 55 mm or less, and a non-round cross-sectional shape. The blend can be made into nonwoven webs for heat-bonding and subsequent use as thermal insulation in, e.g., outerwear, bedding, etc. The cellulose acetate fibers provide superior thermal insulation clo value relative to at equivalent loft.

COMPOSITION OF MATTER EFFLUENT FROM REFINER OF A WET LAID PROCESS

A composition and process for making the composition by co-refining: fibrillated virgin cellulose fibers, waste/recycle cellulose fibers, or both; co-refined cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3 and the weight percent of CE staple fibers is less than 30 wt. %, based on the weight of CE staple fibers and said cellulose fibers; and water. The composition can be co-refined to obtain lower Canadian standard freeness yet improved drainage and wet laid products having good tensile strength, air permeability, stiffness, burst strength, and bulk.

Filter media comprising binder components

Filter media comprising a non-woven web including one or more binder components are provided. In some embodiments, the non-woven web comprises fibers and one or more binder components (e.g., monocomponent binder fibers, binder particles). The binder component(s) may impart strength and/or durability to the non-woven web without adversely affecting one or more filtration properties (e.g., air permeability, efficiency, dust holding capacity). In such cases, the non-woven web may function as both a filtration and support layer. For instance, the non-woven web may trap particulate matter and allow the filter media to be pleated and/or utilized in a filter element without the need for additional support structures. Filter media described herein may be particularly well-suited for applications such as fuel filtration, hydraulic filtration, lube filtration, gas turbine filtration, air filtration, and water filtration, though the media may also be used in other applications.

A needle punched carpet for use in a car is disclosed. The needle punched carpet comprises at least a needle punched facing layer defining a top layer and made of staple fibers. The staple fibers comprise hollow fibers having a hollow fiber content that is at least more than 45 weight % of the total staple fibers.

Conjugate fiber for air-laid nonwoven fabric manufacture and method for manufacturing a high-density air-laid nonwoven fabric

Provided is a conjugate fiber for air-laid nonwoven fabric manufacture having a planar zig-zag crimp shape before a thermal treatment, such that a uniform web is obtained by air laying with high processability and productivity, and the conjugate fiber develops a spiral crimp when the web is subjected to a thermal treatment to thereby enable the web to shrink significantly, as a result of which a nonwoven fabric can be obtained in which fibers are amassed to a high density. The conjugate fiber for air-laid nonwoven fabric manufacture is a heat-fusible conjugate fiber in which a first component comprising an olefinic thermoplastic resin is conjugated with a second component comprising an olefinic thermoplastic resin having a melting point higher than that of the first component. The conjugate form is such that the centers of gravity of the conjugate components are mutually different in the fiber cross section, the fiber has a single-yarn fineness of 1 to 10 dtex, a fiber length of 3 to 20 mm, and a planar zig-zag crimp whose crimp shape index (actual length of short fiber/distance between both ends of short fiber) ranges from 1.05 to 1.60, and the web shrinkage upon thermal treatment at 145 C. of a web obtained by an air-laid method is not lower than 40%.
