A thermal insulation sheet is used that includes a fiber, a silica aerogel contained in the fiber, and a fibrous cavity. A method for manufacturing a thermal insulation sheet is used that includes: an impregnation step of impregnating a silica aerosol in a nonwoven fabric substrate containing a fiber that is insoluble in an acidic solution, and a fiber that is soluble in the acidic solution; a gelling step of gelling the silica aerosol; a hydrophobizing step of hydrophobizing the gel; and a drying step of drying the gel. The fiber that is soluble in the acidic solution is dissolved in the hydrophobizing step.

A liquid-crystal polyether fiber with high tensile strength has an ash content of 0.3 percent by weight or less, a degree of fusion (f) of 3 or less, and a tensile strength of 18 cN/dtex or more. The liquid-crystal polyether fiber has few residues of an anti-fusion agent and causes no fusion between filaments.

Temperature management bedding systems for mattresses and quilt panels generally include a trilayer of active components including a phase change material applied to a top surface of a flexible substrate thereof, a fire retardant layer underlying the flexible substrate including hydrophilic rayon fibers treated with ammonium polyphosphate; and a vertically oriented fiber batting layer underlying the first retardant layer including an elastomeric binder. The temperature management bedding systems provide heat control and mass transfer of moisture from the bedding surface.

Disclosed is a method for the use, as fire-retardant, of an aqueous composition including chitosan and at least one mineral filler, the inorganic filler being for example chosen from the group of mineral fillers in laminae, in particular chosen from the group consisting of talc, montmorillonite, saponite, sepiolite, bentonite, smectite, hectorite, kaolinite, halloysite and mica, and mixtures thereof.

The present disclosure provides a method for producing a cell-culturing polyvinyl alcohol-based nanofiber structure, the method comprising: electrospinning an electrospun solution to form a nanofiber mat, wherein the electrospun solution contains polyvinyl alcohol (PVA), polyacrylic acid (PA) and glutaraldehyde (GA); crosslinking the nanofiber mat via a hydrochloric acid (HCl) vapor treatment; and treating the crosslinked nanofiber mat with dimethylformamide (DMF) solvent to crystallize the nanofiber mat.

A biocide-free sponge cloth prewetted with a hygroscopically acting inorganic salt is provided. The spone cloth is based on regenerated cellulose which is mechanically reinforced with fibers and/or a web and includes a hygroscopically acting salt. The sponge cloth has an a.sub.w value of less than 0.80. On account of the low a.sub.w value, the sponge cloth has an antibacterial, bacteriostatic, fungicidal and/or fungistatic effect. The hygroscopically acting salt is preferably magnesium chloride. It can be combined with further inorganic salts, with low molecular weight, mono- or polyhydric alcohols, with sugars, sugar esters, mono- or polybasic carboxylic acids, esters of mono- or polybasic carboxylic acids and/or with hydrophilic polymers. The sponge cloth is preferably produced by the viscose process.
