A sizing composition, in particular for insulating products based on mineral wool, in particular of glass or of rock, includes at least one non-reducing saccharide, at least one hydrogenated saccharide, and at least one polycarboxylic organic acid.

A lightweight heat-preserving fiber and a preparation method thereof are provided, wherein the fiber is prepared by measuring, composite spinneret's extruding, cooling, oiling, drawing, heat setting and winding a polyester melt. The composite spinneret has a hollow spinning hole and a circular spinning hole. The ratio of the micropore length of hollow spinning hole to circular spinning hole equals to the ratio of the equivalent diameter of hollow spinning hole to circular spinning hole multiplies the coefficient K, and the equivalent diameter is the ratio of the cross-sectional area to the circumference of the cross-section, the coefficient K ranges from 0.97 to 1.03. The oil agent contains a crown ether, and the content of the crown ether ranges from 67.30 to 85.58 wt %. The thermal conductivity of a knitted fabric having a basis weight of 100 g/m.sup.2 prepared by lightweight heat-preserving fiber is no larger than 0.150 W/m.Math.K.

The present invention relates to a liquid-state temporary reinforcing material, a preparation method therefor and an application thereof. The liquid-state temporary reinforcing material comprises a reinforcing material and a crystallization inhibitor; the reinforcing material is selected from molecules of any two or more of menthol, menthone, menthol ester and menthol ether, and the content of the crystallization inhibitor is less than 50 ppm. For the liquid-state temporary reinforcing material of the present invention, the menthol and the derivatives of the liquid-state temporary reinforcing material are integrally mixed together to form the composite material for temporary reinforcing, the composite material being liquid and volatilization-controllable at room temperature. Thus, the temporary reinforcing requirements for extracting cultural relics at an archaeology excavation site may be met, and the material is convenient to use.

An ink jet composition according to the present disclosure contains a flameproofing agent and resin particles. The resin particles are preferably urethanic resin particles. It is preferable that a urethanic resin making up the urethanic resin particles is a urethanic resin containing a crosslinking group and the crosslinking group is one or more selected from the group consisting of a blocked isocyanate group and a silanol group. The urethanic resin making up the urethanic resin particles preferably has a polycarbonate skeleton.

Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca.sup.2+, Mg.sup.2+, Ba.sup.2+, Al.sup.3+, Fe.sup.2+, Fe.sup.3+, etc.). The sequestrant reduces a precipitation rate for the multivalent ions from the aqueous binder composition. Methods of reducing salt precipitation from a binder composition are also described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition.
