Methods of manufacturing multifilament yarns of filled high-performance polyethylene (HPPE) fibers that are formed of HPPE filled with a hard component having a Mohs hardness of at least 2.5 are provided. The methods include applying a solvent solution or an aqueous suspension of a polymeric resin to the filled HPPE fibers and thereafter at least partially drying the solvent solution or aqueous suspension to obtain the yarn. The polymeric resin is a homopolymer of ethylene or propylene or is a copolymer of ethylene and/or propylene, and has a density as measured according to ISO1183-2004 in the range from 860 to 970 kg/m, a melting temperature in the range from 40 to 140° C. and a heat of fusion of at least 5 J/g.

Method of manufacturing multifilament yarns of filled high-performance polyethylene (HPPE) fibers

A chain link having a strip which includes warp yarns and weft yarns is provided, with the warp yarns containing a warp yarn A and a warp yarn B, with the minimum creep rate of warp yarn B being higher than the minimum creep rate of warp yarn A, wherein the strip comprises a longitudinal core section and at least two longitudinal edge sections, and wherein the concentration of warp yarn A in the core section is higher than the concentration of yarn A in the edge sections of the strip and the concentration of warp yarn B in the edge sections is higher than the concentration of warp yarn B in the core section of the strip. The invention also relates to a chain comprising said chain link and to use of said chain in different applications.

Hybrid chain link

A chain includes a plurality of interconnected chain links, wherein at least one of the chain links comprises a Turk's head braided core having at least two consecutive turns of at least one primary strand. The at least one primary strand includes polymeric elongated elements having a tenacity of at least 1.0 N/tex.

Chain with endless braided chain-link

The invention relates to an endless shaped article comprising at least one strip of material forming a plurality of convolutions of the strip of material, the strip having a longitudinal axis, wherein each convolution of said strip comprises a twist along the longitudinal axis of said strip, wherein said twist is an odd multiple of 180 degrees. The invention also relates to a method to manufacture said article, and its use as sling, loop, belt or chain link.

Endless shaped article

The present invention relates to a chain link comprising a strip comprising warp yarns and weft yarns, with the warp yarns containing warp yarn A and warp yarn B, with the minimum creep rate of warp yarn B being higher than the minimum creep rate of warp yarn A, wherein the strip comprises a longitudinal core section and at least two longitudinal edge sections, and wherein the concentration of warp yarn A in the core section is higher than the concentration of yarn A in the edge sections of the strip and the concentration of warp yarn B in the edge sections is higher than the concentration of warp yarn B in the core section of the strip. The invention also relates to a chain comprising said chain link and to use of said chain in different applications.

A chain is provided which includes a plurality of interconnected chain-links. At least one chain-link of the chain has a braided core which includes a first primary strand having polymeric elongated elements having a tenacity of at least 1.0 N/tex. The braided core is braided from at least 2 consecutive turns of the primary strand. Also disclosed is a braided endless shaped element suitable as chain-link for the chain as well as a chain which has a tenacity (Ten) in N/Tex and a combined titer of the 2 legs of the chain-link having polymeric elongated elements (T) in MTex satisfying the relationship of Ten&#x2265;0.50*T&#x2212;0.05.

The present invention relates to a chain link comprising a strip comprising a longitudinal core section and at least two longitudinal edge sections, wherein the thickness of the core section is higher than the thickness of the edge sections, preferably the strip comprising warp yarn A and warp yarn B, the titer of warp yarn A being higher than the titer of warp yarn B, and wherein the concentration of warp yarn A in the core section is higher than the concentration of yarn A in the edge sections of the strip and the concentration of warp yarn B in the edge sections is higher than the concentration of warp yarn B in the core section of the strip. The invention also relates to a chain comprising said chain link and to the use of said chain in different applications.

The present invention relates to a chain comprising a plurality of chain links comprising a polymeric fiber and wherein said chain comprises at least one spacer having a thickness &#x394; at the contact location through which loads are directly transmitted between said chain links and a ratio &#x394;/&#x3c4;=f, with &#x3c4; being the thickness of any of the chain links at the contact location through which loads are directly transmitted between said chain links and f being in a range between 0.10 and 2.50. The invention further relates to the use said chain for storing, securing, lashing and tying down for handling and transporting cargo, in lifting and hoisting, logging, hauling and rigging, propulsion and driving, mooring, cargo-hold of an aircraft or naval ship.
