A female loop portion for a hook and loop self-adhesive, comprising a film (1) made of at least one thermoplastic and a plurality of filaments (2) which are separate from one another and attached to one of the surfaces of the film, each filament comprising a series of fastening sections (15) and a series of loop sections (4) alternating with the fastening sections, the filaments being attached to the film along the fastening sections while the loop sections are at a distance from the film so as to form loops, and characterized in that a cross-sectional area of one loop section of a filament is less than a cross-sectional area of one fastening section of said one filament.

The invention provides a polyester resin for heat-shrinkable film which contains terephthalic acid as a main component of a dicarboxylic acid component, contains ethylene glycol as a main component of a diol component, and contains from 18 to 32% by mole of neopentyl glycol and from 7 to 15% by mole of diethylene glycol when a total amount of the whole diol component in total polyester resin components is taken as 100% by mole. The polyester resin has (i) an intrinsic viscosity (IV) of not less than 0.65 and less than 0.70 dl/g, (ii) a carboxyl end group concentration (AV) of 8-25 eq/t, (iii) a color b value of 1.0-8.0 in an L*a*b* color system, and (iv) aluminum and phosphorus atoms, wherein the aluminum atoms are present in an amount of 15-40 ppm, and wherein the molar ratio of the phosphorus atoms to the aluminum atoms is 1.8-2.6.

A leaflet for a prosthetic valve formed of at least one layer that includes a composite material containing at least one expanded fluoropolymer membrane having serpentine fibrils and an elastomer is provided. The fluoropolymer may be polytetrafluoroethylene. In at least one embodiment, the elastic properties are present in an axial direction the leaflet. The leaflets may be single layered or multi-layered. The leaflets may be coupled to a support structure and movable between open and closed configurations relative to the support structure to form a heart valve. The elasticity within the leaflets permits, among other things, the leaflets to bend with a reduced occurrence of wrinkles as the valve opens and closes. The elastic properties of the leaflet also, among other things, improve bending properties and reduce closure stresses, thereby extending the life of the leaflet.
