The cleaning wipe includes a fibrous layer having fibers of a melt spinnable sustainable polymer; and an abrasive layer having meltblown fibers of a melt spinnable sustainable polymer. The abrasive layer defining an outer surface of the cleaning wipe, and includes a plurality of abrasive structures formed thereon in which the abrasive structures are formed from conglomerated fibers, meltblown shot, fibers having average diameters greater than 4 micrometers and fibers having a tortuous geometry. The melt spinnable sustainable polymer content of the cleaning wipe is at least 50 weight % by weight of the cleaning wipe. A method of preparing the cleaning wipe is also provided.
USE OF A COMPOSITE MATERIAL AS PACKAGING MATERIAL
A packaging includes a composite material. The composite material includes a barrier layer and a backing layer. The backing layer includes a spunbonded nonwoven, arranged on at least one side of the barrier layer and bonded to the barrier layer by heat and pressure. The barrier layer includes a nonwoven containing 1 to 70 wt % melt-blown fibers and 30 to 99 wt % staple fibers, relative to a total weight of the nonwoven in each case.
Protective fabric and protective product
A protective fabric which includes at least one structural layer and a ceramic composite material layer fixed to the at least one structural layer, is provided. The structural layer can include a non-woven material made from or containing synthetic fibers. The ceramic composite material layer is formed of ceramic composite material powder which includes a ceramic carrier, and iron-silver crystals containing zero-valent iron and zero-valent silver supported on the ceramic carrier. The protective fabric is effective for removing VOCs, suppressing bacterial growth, and filtering or inactivating virus, such as SARS-CoV-2 virus. Protective products or articles incorporating the protective fabric are also provided.
FILTER MATERIAL USED FOR AUTOMOBILE AIR CONDITIONING AND CAPABLE OF FILTERING OUT VOLATILE ORGANIC COMPOUND (VOC) GAS, AND PROCESS THEREOF
The present disclosure provides a filter material used for automobile air conditioning and capable of filtering out volatile organic compound (VOC) gas, including a sandwich structure (100) and an activated carbon fiber (ACF) non-woven fabric layer (200) located at one side of the sandwich structure (100), where, the ACF non-woven fabric layer (200) is composed of interleaved ACFs, and the ACF non-woven fabric layer (200) is compounded with the sandwich structure (100) via hot melt adhesive (HMA) (210).
Nonwoven Fabric for Sterilization Packaging Material
The present invention provides: a non-woven fabric for a sterilization packaging material, the non-woven fabric being capable of being compatible with all sterilization treatment methods and maintaining a sterile state in the interior without breaking even in a variety of environments in which the non-woven fabric can be assumed to be used as a sterilization packaging material; and a non-woven fabric for a sterilization packaging material, the non-woven fabric achieving both easy-peel properties that enable easy handling without breakage and barrier properties for retaining the sterile state in the interior. The non-woven fabric for a sterilization packaging material according to the present invention is characterized in having, as an obverse-layer heat seal surface, a fiber layer (I) that has a void ratio of 30-60% inclusive, and having, as a barrier layer, a fiber layer (II) that has a fiber specific surface area ranging from 1.0 m.sup.2/g to 10 m.sup.2/g and has a one-centimeter-equivalent fiber count of 800-1,000,000 inclusive per milligram, the fiber layer (I) and the fiber layer (II) being laminated. In addition, the non-woven fabric for a sterilization packaging material is characterized in having a weight-average fiber diameter of 3-30 μm inclusive and a formation coefficient of 1.0-5.0 inclusive.
NONWOVEN ANTIMICROBIAL AND ANTIVIRAL PROTECTIVE BARRIER
A protective barrier having antimicrobial and antiviral properties. A filtration media structure is constructed from an inner media layer and an outer media layer. The inner and outer layers are spunbond and may be nonwoven or woven. An antimicrobial additive of silver and copper is compounded into a polypropylene base to form each of the layers. A middle layer of melt blown nonwoven filtration media layer may be encapsulated between the inner and outer media layers. The middle layer may also be constructed with the antimicrobial additive of silver and copper for enhanced antimicrobial protection. A channeling layer may also be sandwiched between the inner and outer media layers. The channeling layer comprises a plurality of filaments having a non-round or round cross-section. The filaments are arranged in a three-dimensional (3D) structure configured to disturb laminar flow through the protective barrier and increase contact with the antimicrobial additive.
PROTECTIVE FABRIC AND PROTECTIVE PRODUCT
A protective fabric which includes at least one structural layer and a ceramic composite material layer fixed to the at least one structural layer, is provided. The structural layer can include a non-woven material made from or containing synthetic fibers. The ceramic composite material layer is formed of ceramic composite material powder which includes a ceramic carrier, and iron-silver crystals containing zero-valent iron and zero-valent silver supported on the ceramic carrier. The protective fabric is effective for removing VOCs, suppressing bacterial growth, and filtering or inactivating virus, such as SARS-CoV-2 virus. Protective products or articles incorporating the protective fabric are also provided.
VACUUM CLEANER FILTER BAG HAVING IMPROVED WELD SEAM STRENGTH
The invention comprises a vacuum cleaner filter bag with a bag wall, comprising: a support layer comprising recycled polyethylene terephthalate, rPET; a fine filter layer of a meltblown non-woven fabric comprising polypropylene, PP, PET and/or recycled polypropylene, rPP; and a capacity layer of a non-woven fabric comprising rPET, recycled textile material, TLO, and/or rPP; wherein the bag wall moreover comprises at least one intermediate layer formed of a non-woven fabric or a fibrous web and comprising rPP as a main component; and wherein the at least one intermediate layer is arranged between the support layer and the fine filter layer and/or between the fine filter layer and the capacity layer.
