The present invention provides super-hydrophobic fabrics and a preparation method thereof, and belong to the field of textiles. The super-hydrophobic fabrics are obtained by finishing Pickering emulsion formed by amphiphilic particles stabilizing low-surface-energy substances in water. Via a one-step finishing method using Pickering emulsion technology, facile preparation of durable super-hydrophobic fabrics is realized. The static contact angle between the finished fabric surfaces and water droplets is greater than 150 degrees, and the water droplets can roll off easily; and after being subjected to 30 times of standard washing tests, the finished fabrics still maintains excellent water repellency. In addition, the Pickering emulsion preparation and finishing process of the present invention are environmentally friendly, pollution-free, facile to operate and widely applicable.

A composition comprising a plurality of particles, wherein said particles comprise: 40 to 95 w.t. % polyethylene glycol, wherein the polyethylene glycol has a weight average molecular weight from 4000 to 12000; 0.1 to 50 w.t. % anhydrous saccharide comprising one to ten monosaccharide units; and 0.1 to 20 w.t. % perfume materials.

There is provided a synthetic polymer fibre having an amorphous phase of at least 10% of the crystallinity ratio. The synthetic polymer fibre includes 0.1 to 5.0 wt. % of a biodegradation—inducing additive with respect to the total weight of the synthetic polymer fibre. The biodegradation-inducing additive is incorporated in the amorphous phase such that the biodegradation-inducing additive is physically and/or chemically accessible for a biodegradation initiation to form nuclei of biodegradation within the amorphous phase.

Disclosed is a malodor control system that includes use of a malodor scavenger to sequester a malodor molecule to reduce and/or eliminate the noxious odor the malodor molecule generates. Some embodiments can include use of a substrate as a non-woven fabric sheet as a delivery system for the malodor scavenger. The substrate can include a polymer complexed with active ingredient to lock the active ingredient in place at a surface of the substrate via a binder so that the active ingredient is present at a predetermined activity level. After interacting with malodor molecules, at least some of the active ingredient migrates via passive diffusion to the substrate surface to maintain the predetermined activity level. Embodiments of the substrate are made from a blend of polyester and rayon, wherein rayon is made using viscose, allowing the substrate to be biodegradable and to handle an increased load of active ingredient.

An environmentally friendly, formaldehyde-free, aqueous binder composition that includes a carbohydrate, a crosslinking agent, and a pre-reacted product of an alcohol or polyol and monomeric or polymeric polycarboxylic acid or polyglycerol is provided. The pre-reacted product may include glycerol and esters of citric acid such a monoglyceryl citrate, diglyceryl citrate, and triglyceryl citrate as well as other higher molecular weight citric acid-based esters. The inclusion of the pre-reacted product in the binder composition helps to speed the crosslinking reaction, induces faster water evaporation, decreases the viscosity of the binder, helps to reduce the amount of water needed for application of the binder, decreases tackiness, and helps to achieve a maximum vertical expansion of the insulation pack in the transfer zone. The binder composition may be used in the formation of insulation materials and non-woven chopped strand mats.
