A method for manufacturing of a multilayer PVC semi-finished product, in particular a multilayer PVC synthetic leather or a multilayer PVC foam sheet, the method comprising the steps of:

a. Coating a coated or uncoated carrier web with a PVC plastisol, whereby a carrier web coated with an ungelled plastisol layer is obtained; thereafter
b. Gelling the ungelled plastisol layer, whereby a carrier web coated with a gelled plastisol layer is obtained; and thereafter
c. Cooling the carrier web coated with the gelled plastisol layer; characterized in that the coating comprises coating the carrier web with at least two PVC plastisols one above the other, simultaneously or in immediate succession. A corresponding apparatus is further described.

The present disclosure relates to the use of eggshell particles as a polymer thermal stabilizer, preferably as a poly(vinyl chloride) (PVC) thermal stabilizer; also to a flexible material comprising a multi-layered PVC-based material, method of obtaining and uses thereof.

An aspect of the present disclosure relates to a material comprising a poly(vinyl chloride), PVC, layer comprising eggshell particles, wherein the eggshell particle size is up to 200 μm, an intermediate layer or a plurality of intermediate layers; a support layer selected from the following list: fabric, knitted fabric, nonwoven, foam, or mixtures thereof; wherein the layers are bounded. Preferably a material solution free of azodicarbonamide, for automotive Interiors—Eco-friendlier, preferably sustainable artificial leather for automotive upholsteries.

A radiative cooling fabric comprises a flexible substrate layer and a functional layer stacked in order. The first functional layer comprises a first functional resin and a first functional filler dispersed in the first functional resin. A mass fraction of the first functional filler in the first functional layer is in a range of 1% to 20%. An emissivity of the radiative cooling fabrics in the wavelength of 7 μm to 14 μm is not less than 80%. A reflectivity of the radiative cooling fabrics in the wavelength of 300 nm to 2500 nm is not less than 80%. An average value of warp recovery angles of the radiative cooling fabrics is greater than or equal to 95°, and an average value of the weft recovery angles of the radiative cooling fabrics is greater than or equal to 91°.

A stitched fabric including a barrier layer; a yarn stitched through and forming stitch holes in the barrier layer, and a coating. A melted portion of the barrier layer fills a portion of the stitch holes. The coating occupies interstitial spaces between individual strands of the yarn to prevent a liquid from passing from one side of the stitched fabric to another side of the stitched fabric via the yarn.

A carrier material for vinyl floor covering, wherein the carrier material includes a nonwoven layer containing at least 50 wt. % of thermoplastic fibers and a scrim for eliminating wrinkles in the vinyl floor covering. The scrim includes weft yarns having a linear density of 28 tex or less. The carrier material prevents the formation of surface irregularities and printing errors in the vinyl floor covering.
