FIELD: production of non-woven materials from polyester composite filaments.
SUBSTANCE: material is formed from short composite filaments made from polyester polymer, prepared from the following catalyst, and polymer providing linking by fusing. Catalyst includes: mixture of component of phosphorous compound of formulation (III) and component of titanium compound of formulation (I), and/or product of reaction of titanium alkoxide and carbonic acid of formulation (II), or acid anhydride; and/or product of reaction of component of phosphorous compound of formulation (V) and component of titanium compound containing titanium alkoxide (IV) of formulation (IV), and/or product of reaction of titanium alkoxide and carbonic acid, of formulation (II) or anhydride thereof.
EFFECT: improved color tint and increased strength of filaments.
