[0148] The coated fabrics of Examples 16 through 24 find use in artificial leather.

example 16

[0149] Example 15 repeated except that the polymer formulation does not contain Silcat R and ATH, but includes 11.4 parts of Perkadox 14S and 5 parts of Perkalink 300. The polymer formulation is applied onto FAB3 as described in Example 15. A standard mat lacquer is applied. Subsequently the polymer coating is foamed in an oven at 200° C. during 2 minutes. The foamed structure is then embossed in a hot platen press at about 100° C.

example 17

[0150] 80 parts of ESI-6 are blended with 20 parts of Affinity HF 1030 polyolefin plastomer. This blend is mixed with 8 parts of ultra fine calcium carbonate, 2 parts of titanium dioxide, 2 parts of Perkadox 14S, 2 parts of Porofor ADC LC2, 0.1 parts of Irganox B225, 0.5 parts of zinc stearate, 0.5 parts of zinc oxide, and I part of stearic acid. This formulation is coated onto FAB3, a mat lacquer is applied to the resulting coating and the coating is foamed as described in Example 15.

Abstract

A multilayer structure comprising (A) a fabric and (B) a polymeric layer comprising a substantially random interpolymer comprising in polymerized form i) one or more α-olefin monomers and ii) one or more vinyl or vinylidene aromatic monomers and / or one or more sterically hindered aliphatic or cycloaliphatic vinyl or vinylidene monomers, and optionally iii) other polymerizable ethylenically unsaturated monomer(s); layer (B) being free from a substantial amount of tackifier. The multilayer structure has desirable haptics and surprisingly good drape properties. It is useful in many applications, for example as water-impermeable clothes, tablecloths, tents, water-impermeable covers, curtains, artificial leather or upholstery.

Description

BACKGROUND OF THE INVENTION [0001] This invention concerns multilayer structures comprising a fabric and a polymeric layer and methods of preparing them. [0002] Multilayer structures that comprise a fabric and a polymeric layer are generally known in the art. They find wide use where impermeableness to water is desired, for example as water-impermeable covers, such as tablecloths, tarpaulins, tents or water-impermeable clothes, such as raincoats. [0003] Multilayer structures, which contain a woven fabric that is coated with a flexible polyvinyl chloride film are widely used due to their excellent flexibility and drape properties. However there is an increasing pressure to find more environmentally friendly films for coating fabrics. Polyethylene films are environmentally friendly. U.S. Pat. No. 5,795,516 relates to a method of fabricating olefin tarpaulins. However, polyethylene films have failed in several applications due to insufficient drape properties. Good drape properties are...
