Provided herein is a carbinol-functional silicone resin. The carbinol-functional silicone resin is prepared by reacting a raw silicone resin having at least 1 mass % of silicon atom-bonded hydroxyl groups, silicon atom-bonded alkoxy groups, or a combination thereof, and a dihydroxy-functional compound, in the presence of a condensation catalyst and a solvent. The carbinol-functional silicone resin can produce a solid silicone-modified polyester without gelation of the silicone resin.

A production method for obtaining a compound having an amide bond and also having an alkoxysilyl group by a reaction of a compound including a carboxy group with a compound having an amino group and an alkoxysilyl group, the production method comprising: a step of conducting the reaction using a triazine-based amidating agent and under a basic condition.

A type of feather-like polyester fiber and a preparing method thereof are disclosed. The preparing method is to manufacture filament from a modified polyester through a POY process with a four-fold flat spinneret and a successive DTY processes, wherein said modified polyester is the product of the esterification and the successive polycondensation reactions of evenly mixed terephthalic acid, ethylene glycol, main-chain silicated diol and fluorinated dicarboxylic acid, and the spinneret is the one set with four-fold flat shaped orifices. The obtained fiber has a dye uptake of 89.6-93.7% when dyed at 130 C., and has an intrinsic viscosity drop of 13-20% when stored at 25 C. and R.H. 65% for 60 months. This invention is simple to apply and features a product with good dyeing and degradation performance.
