A high density mineral fibre board having a formaldehyde free binder has acceptable strength and good dimensional stability.

A method of manufacturing a mineral fiber insulating board comprising i) spraying a formaldehyde-free aqueous binder solution onto a plurality of mineral fibers to provide uncured binder disposed on the plurality of mineral fibers, ii) passing the plurality of mineral fibers having uncured binder disposed thereon through a curing oven to cure the uncured binder and provide the mineral fiber insulating board with a cured binder disposed on the plurality of mineral fibers in about 0.5%-15% by weight as determined by loss on ignition, wherein the binder is based on reducing sugar(s) and the cured binder includes at least one reaction product of the reducing sugar(s) and an amine reactant.

The present invention relates to a process for producing an esterquat by a transesterification reaction of a fatty acid oil or a mixture comprising one or more fatty acid oils and one or more fatty acids with a tertiary hydroxy amine and then a quaternization reaction. Esterquats obtained by the method of the invention show beneficial properties in particular when used as active component in fabric softener materials.

A fiber treatment agent can provide artificial hair fiber with smooth and dry texture. A fiber treatment agent includes water; silicone oil; and ionic liquid. Content of the sum of the silicone oil and the ionic liquid with respect to the water is 2 parts by weight or more and less than 10 parts by weight. Content of the silicone oil with respect to the weight of the water is more than 0.5 parts by weight and 9.5 parts by weight or less. Content of the ionic liquid with respect to the weight of the water is 0.2 parts by weight or more and 5.0 parts by weight or less.

A method for fusing aramid fibers, wherein a) at least one area of an aramid fiber is treated with an ionic liquid so that the aramid is partially dissolved, b) the aramid fiber is contacted via the dissolved area with another aramid fiber area with pressure being applied to the contact area, and subsequently c) the partially dissolved area of the aramid is re-coagulated.
