A structure having a tunable modulus of bending (flexibility) composed of interlocking geometric particles arranged such that an external pressure/force causes them to jam together, increasing the stiffness of the overall structure. Methods for creating the external pressure can include the use of an envelope around the structure that can be evacuated of air.

The invention pertains to a method to manufacture a textile product comprising a first sheet having polyester yarns fastened to this sheet to form a pile thereon, the method comprising providing the sheet, stitching the polyester yarns through the sheet to form the pile on a first surface of the sheet and loops of the yarns at a second surface of the sheet, contacting the second surface of the sheet with a surface of a hot body to at least partly melt the loops of the yarns to fasten the yarns to the sheet, wherein the second surface is actively cooled to force the temperature to be below the glass transition temperature of the polyester yarns within 60 seconds after the contacting of the second surface with the hot body. The invention also pertains to a device for applying this method.

An interior trim part made by a method that includes the steps of bringing a fiber web onto a conveyor, needlepunching the fiber web to form a base in contact with the conveyor, and introducing a binder component on the base. The binder component introduced on the base is a thermoplastic polymer in solid form. The method includes a step for heating the base to cause the thermoplastic polymer making up the binder component to penetrate the base over a thickness smaller than the thickness of the base.

The invention relates to a planar textile substrate comprising on a surface a coating that contains a water-activated adhesive, said adhesive representing an aqueous dispersion of the following composition.

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.

Carpet tile which includes a base layer having a top side and a bottom side, wherein preferably pile yarns are provided on the top side of the base layer, and a backing layer fixedly connected to the bottom side of the base layer. The backing layer constitutes a bottom surface of the carpet tile, wherein on the bottom surface of the carpet tile an adhesive is applied, and wherein the adhesive imparts adhesive properties to the bottom surface which are sufficient to allow the bottom surface to be attached to a suitable support surface, as well as to be detached from the same support surface onto which it has been attached previously.

A method of manufacturing an artificial turf includes creating fluid polyurethane mass. The creation including reacting first and second polyols with an isocyanate. The first polyol is a polyether polyol and/or a polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadien diol. The isocyanate including isocyanate monomers, isocyanate polymers or isocyanate prepolymers or a mixture thereof, the isocyanate monomers, isocyanate polymers and the isocyanate prepolymers having two or more isocyanate groups per molecule. The method further includes incorporating an artificial turf fiber into a carrier such that a first portion of the fiber protrudes to the front side of the carrier and that a second portion of the fiber is located at the back side of the carrier, adding the fluid polyurethane mass on the back side of the carrier, and hardening the fluid polyurethane mass.
