The present invention relates to thermal bondable fibers comprising a random polymer of propylene with one or more olefins comonomers different from ethylene, to the process for preparing said fibers, and to the thermally bonded articles obtained from said fibers. Fibers of certain thermoplastic materials are used widely in the manufacturing of thermally bonded products.

Thermal bondable polyolefin fibers comprising a random copolymer of propylene

Process for the production of a high tenacity propylene polymer fiber which comprises:

High tenacity propylene polymer composition

High tenacity propylene polymer fiber and process for making it

Process for the production of a high tenacity propylene polymer fiber which includes:

Polyolefin fibers, suitable for the preparation of nonwoven fabrics, prepared by using a spinneret or extruder with dies having a real or equivalent output diameter of the capillaries or holes greater than 0.4 mm, with the proviso that for fibers having a denier greater than or equal to 4 dtex, the ratio of the output capillary or hole diameter to the denier is greater than or equal to 0.06 mm/dtex.

Spinning process for the preparation of high thermobondability

An olefin polymer composition is disclosed which comprises (by weight):

Compositions for polyolefin fibers having improved flame-resistance and
