Autoadhesive Bonding of Modified Polyester Fibres

An efficient method of autoadhesive bonding of polyester fibres in a high-strength nonwoven textile was developed. The method includes application of a small amount (0.25 wt. %) of a new organosilicon modifier — oligo(ethoxy)(isobutoxy)siloxane — on washed fibres and pressing under a pressure of 2 MPa for 2 min. The method allows reducing the pressing temperature by 5-6°C and elimiantes the use of 30-40 wt. % traditional bonding substances.

Fibres and Fabrics with Lasting Scent. Immobilization of Fragrant Alcohols on the Surface of Fibres

A method for fabrication of fibres and nonwovens with lasting scent and an effective method of autoadhesive bonding of fibres in nonwovens with a small amount, 0.25-0.30 wt. %, of polydimethylvinyl(alkoxy)silazanes that eliminates use of 30-40 wt. % traditional binders are developed. New organosilicon modifiers of fibres and fabrics are synthesized — polydimethylvinyl(alkoxy)siloxazanes containing a fixed amount of isobutoxy, beta;-phenylethoxy, γ-phenylpropenyloxy, and cyclogeraniolyloxysilyl groups capable of giving the materials a lasting scent that persists after laundering.
