Abstract:
A towel or wipe including a fibre web having a first face and an opposing second face. A coating of material is provided on fibres of the fibre web to form a layer at the first face. The material may be liquid repellent and/or a barrier to liquid vapour or liquids, so as to prevent the first face from becoming wet and/or preventing evaporation of liquid vapour.
Abstract:
Self-cleaning, odorless, and/or eco-friendly denim fabrics, including one or more implementations that are woven/knitted with silver bonded filaments or staple silver fibers or coated with anti-microbial and anti-odor treatment. In some embodiments, the strength of the anti-microbial and anti-odor properties may vary at the time of coating the fabric or at the time of weaving/knitting based on the ratio use of silver filament/staple silver fibers compared to the ratio of other yarns in the fabric.
Abstract:
The invention provides a method for treating textile material to inhibit or reduce release of formaldehyde from the textile material. The invention also provides a method for treating textile material without the use of formaldehyde or formaldehydic compounds in the treatment compositions. The resulting textile material is environmentally friendly and can exhibit a high degree of oleophobic, hydrophobic, superoleophobic, superhydrophobic, superhydrophilic, omniphobic, hydrophilic/wicking, abrasion resistance, electrical conductivity, thermal conductivity, anti-fungal and/or anti-bacterial properties textile surfaces. In some cases, the resulting textile material exhibits multivalued oleophobic, hydrophobic, hydrophilic, superoleophobic, superhydrophobic, superhydrophilic and/or omniphobic textile surfaces which can repel soil and/or water at extremely low-surface-tension without sacrificing aesthetic qualities.
Abstract:
A fluorine-free composition includes at least one polycarbodiimide compound derived from a carbodiimidization reaction of a carbodiimidization reaction mixture comprising at least one oligomer, wherein the oligomer comprises at least one isocyanate end group and at least two repeating units, wherein each of the at least two repeating units comprises at least one hydrocarbon group having at least 16 carbon atoms. The composition may also include at least one paraffin wax. Such compositions are useful for treating fibrous substrates to enhance their water-repellency.
Abstract:
According to some aspects, water repellent treatments for fabrics. More particularly, systems and methods for water repellant treatment of protective fabrics for ballistic and other applications, and protective fabrics made using such techniques.
Abstract:
A foam composition and a process to treat fibrous articles using a foam composition comprising an amphiphilic protein. The foam composition can impart oil and water repellency when a fluorinated additive is used. The foam composition can impart water repellency when a non-fluorinated additive is used. The described amphiphilic proteins can be hydrophobins. The density of the foam suitable for the process is from about 0.001 to about 0.5 gram per milliliter.
