Claims
- 1. A textile sizing composition for a fibrous textile yarn consisting of a mixture of
- I. an unsaturated polyester comprising the reaction product of:
- (a) at least one polycarboxylic acid reactant comprising (1) a dicarboxylic acid reactant selected from the group consisting of dicarboxylic acids, corresponding dicarboxylic anhydrides, dicarboxylic acid esters, and their corresponding acyl halides or (2) a mixture of said dicarboxylic acid reactant with up to 20 mole percent of a polycarboxylic acid reactant having a functionality greater than two based upon 100 mole percent of said dicarboxylic acid reactant and
- (b) at least one polyhydric alcohol reactant comprising (1) a diol or (2) a mixture of a diol and up to 20 mole percent of a polyhydric alcohol having a functionality greater than two based upon 100 mole percent of said polyhydric alcohol,
- wherein a minor effective proportion of said dicarboxylic acid reactant or polyhydric alcohol reactant is alpha,beta-ethylenically unsaturated with
- II. at least one monovinyl monomer reactant comprising at least one monovinyl monomer having at least one carboxylic group or a mixture of said vinyl monomer with any monofunctonal vinyl monomer
- wherein said mixture is capable of being applied to said yarn as a solventless mixture of reactants, which can hardened by the application of heat or radiation, and which can be removed therefrom by neutralization or partial neutralization of said composition.
- 2. The composition of claim 1 wherein said composition is the reaction product of a saturated aromatic dicarboxylic reactant and an .alpha.,.beta.-ethylenically unsaturated aliphatic dicarboxylic reactant with a diol and said unsaturated polyester has an acid number of about 2 to about 40.
- 3. The composition of claim 2 wherein said textile sizing composition is the reaction product of isophthalic acid, maleic anhydride, diethylene glycol, ethylene glycol, and acrylic acid.
