Provided is a composite thermal insulation sheet including an aerogel and a method for manufacturing the same. The methods yield an ultra-thin aerogel composite sheet having characteristics of low dust, high strength and high thermal insulation, thereby having an increased applicability thereof to an electronic device.

The disclosure relates to seamless manufacturing processes for 3-dimensional waterproof and breathable porous polymer membranes by spraying, dip-coating or painting a substrate with a dispersion having polymer, coated or non-coated particles and diluent and removing the particles by dissolution thus creating porosity after the 3D coating/shaping. The disclosure further relates to dispersions to obtain such membranes, to polymer membranes obtained, to shaped articles containing such membranes; to the use of such membranes, shaped articles and intermediates.

An aspect of the invention provides a protective garment comprising a pair of arms and a body portion having a vertical split along its length, the body portion further comprising an opening for receiving a user's head therethrough, wherein at least a part of the protective garment is manufactured from a water repellent material comprising a polyester base and polyurethane coating having a combined weight of 70 to 100 grams per square meter. Another aspect of the invention provides a protective garment comprising a water repellent material comprising a polyester base and polyurethane coating having a combined weight of 70 to 100 grams per square meter. Such a protective garment could include a gown, drape, or bib, for example.

A coating structure of a blackout advertising cloth, comprising: a warp knitted mesh fabric; a front layer, which is an adhesive slurry layer made of polyacrylic resin as main component mixed with fireproof agent and waterproof agent, the adhesive slurry layer is coated on the front surface of the warp knitted mesh fabric for the slurry penetrating the meshes, so that the warp knitted mesh fabric and the front layer are firmly bonded; and a rear blackout layer, which is a shading slurry layer made of acrylic resin as main component mixed with blackout material, the rear blackout layer is coated on the rear surface, so that the warp knitted mesh fabric and the rear blackout layer are firmly bonded, and further form a coating structure of the blackout advertising cloth.

Objects of the present invention are to provide a woven/knitted fabric that does not inhibit movement of the body and that has excellent wearing feel, and is particularly suitable for use in garments, as well as garments using the woven/knitted fabric. Provided is a woven/knitted fabric at least partially including a false-twist yarn composed of an eccentric sheath-core type polyamide composite fiber having an equilibrium moisture content of 6.3% or less, the woven/knitted fabric having a stress ratio at 15% elongation in the warp direction to the weft direction of from 0.25 to 2.0.

In a first embodiment, the invention provides a composite fabric which contains a first fabric layer and a thin film. The first fabric layer has an upper and lower side and contains a plurality of synthetic polymer fibers. The synthetic polymer fibers contain at least 15% of bio-based carbon content as measured by ASTM D26866-20 Method B. The thin film is located on the lower side of the first fabric layer and contains at least 15% of biobased carbon content as measured by ASTM D26866-20 Method B. The thin film has an average weight of less than about 30 GSM and has an air permeability of less than about 1 CFM as measured by ASTM D737 @ 125 Pa.

A method of maintaining soil strength and stability involves positioning a sheet of soil stabilization and strengthening material on a selected area where the strengthening and stabilization of the soil is desired. The sheet of soil stabilization and strengthening material includes a fabric layer that forms a base of the soil stabilization and strengthening material. The lower surface of the fabric layer is positioned against and engages the selected area. A moisture impervious layer is coupled to the upper surface of the fabric layer. A particulate aggregate material is embedded in the moisture impervious layer.

A liquid repellent cloth or liquid repellent film according to an embodiment includes abase fabric selected from a fiber cloth or a synthetic resin film, and a liquid repellent membrane supported on at least one principal face of the base fabric. The liquid repellent membrane is a monomolecular membrane of a fluorine-containing organic compound that binds to a surface of the base fabric through a binding moiety represented by —Z—O—* (wherein Z represents an atomic group containing a Si atom, and * represents a binding site to the surface of the base fabric) and includes a perfluoroalkyl group having 4 or less carbon atoms at a terminal, and the fluorine-containing organic compound undergoes intermolecular bonding between the fluorine-containing organic compounds adjacent to each other by mutual binding of Z in the formula.

A system and associated method include coconut fiber liners used in hanging wire flower baskets. The coco fiber basket liner may create a water seal in the liner by over-coating a portion of the inner liner with a unique blend of all-natural rubber latex, then molding the liners into shape. The added latex coating may seal in and hold water in the bottom portion of the liner. This feature may keep the soil moist while still allowing air to flow thru the plants. The moisture and airflow may help promote healthier plants and roots and require less watering. Excess water beyond the intended amount may drain out thru the permeable side walls of the coco liner.

The present invention relates to an aqueous dispersion of polyurethane and a method for preparing the same, use thereof in a coating composition, and a coated product. The aqueous dispersion of polyurethane comprises a polyurethane polymer which is obtained by a reaction of a reaction mixture comprising a polyurethane prepolymer A) and an isocyanate-reactive component B), said polyurethane prepolymer A) being obtained by a reaction comprising the following components: A1) a polyisocyanate which has a functionality of not less than 2; and A2) a multifunctional polyether polyol which has a functionality of not less than 3 in an amount of 1% to 30% by weight, based on the amount of said reaction mixture as 100% by weight. The aqueous dispersion of polyurethane according to the present invention is well dispersed, and is capable of forming a coat with good waterproof, moisture permeability and washing resistance.
