A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

A bonding preparation patch for application to a resin treated surface is provided. The patch includes a strip having first and second portions, each of which has corresponding first and second sides. The strip is formed of resin porous material and is foldable such that the respective first sides of the first and second portions face each other. The patch further includes a resin barrier interposable between corresponding portions of the respective first sides and a tape including at least one adhesive side, which is securable relative to the first portion and disposable in contact with the second side of the second portion.

A process for winding a filament around a winding support. The winding support has a cylindrical shape with dome-shaped longitudinal ends and a roll axis, and is held by a holding device fixed to a base. The process includes the following, occurring in synchronization, feeding a filament, by means of at least one feeding device, towards the winding support, rotating the winding support with respect to the base around a pitch axis of the winding support, rotating unlimitedly the at least one feeding device around a yaw axis of the winding support with respect to the base, and/or rotating unlimitedly the winding support around the yaw axis of the winding support with respect to the base, and rotating unlimitedly the winding support with respect to the base around the roll axis of the winding support.

The present invention proposes a fuel tank comprising at least two shells weldable together, each of said at least two shells is made of a polymer composition comprising at least 45% by weight of at least one aromatic polyamide and at least 10% by weight of at least one aliphatic polyamide relative to the total weight of the polymer composition.

Embodiments of the present disclosure are directed to leak-free exercise devices that are soft and conformable due to being filled with granular material. The devices are formed from one or more flexible panels joined together to form a cavity and a filler material, such as sand, contained within the cavity. The devices comprise welded seams that prevent liquid or moisture from entering the cavity and/or granular material from exiting the cavity. In some embodiments, the one or more flexible panels may further be made of waterproof materials.
