A pattern for a chenille carpet pile based on quaternary colors mixing regulation of multicolored filaments and a construction method thereof are disclosed. The construction method regulates the uneven distribution of the multicolored filaments on the chenille carpet pile by changing the combination modes and ratios of the multicolored filaments, thereby producing patterns with hazy, moderate and clear color mixing effects. Different from the additive mixing of color light and the subtractive mixing of pigments, the mixing of single-colored filaments is spatial juxtaposition mixing and non-uniform mixing. The construction method also regulates the mixing ratio of the single-colored filaments and the hue, luminance and saturation differences between the single-colored filaments, such that the chenille pile can visually present hazy, moderate and clear color mixing effects. The entire design implementation of the construction method can effectively improve the efficiency of constructing the pattern of the chenille carpet pile.

A co-foamable vinyl plastisol composition, a gelled or fused co-foamed vinyl layer, a co-foamed vinyl layer, methods of manufacture of the layer and use of the layer in floor coverings such as sheet vinyl, cushioned vinyl flooring, floor tiles, and laminated planks are described. The co-foaming is preferably a sequential foaming of a single layer such as a single coated layer, such as sequentially applied mechanical foaming or frothing followed by chemical foaming. A co-foamable vinyl plastisol composition is mechanically foamed/frothed before it is applied to a substrate. Once on the substrate, the co-foamable layer can be processed further and is chemically foamed in a later process step.
