A synthetic rope (20) comprises a core (22) and at least a first layer surrounding the core (22). The first layer has first layer strands (26). The core has a fluted outer surface with spaced apart helical concave grooves. Each of these grooves contacts one of the first layer strands (26). The grooves have a radius of curvature (24) that is greater than the radius of curvature (14) of a circle having a same diameter as the contacting first layer strand before twisting.

A hookless winch rope for securing to an object includes a first rope having a first end and a second end. The first end has a first loop and comprising a choke. A second rope is separate from the first rope. The second rope includes a third end and a fourth end. The third end includes an enlarged knot forming an engagement notch receiving the first loop. The first rope and the second rope are joined by a first interwoven portion.

The disclosure provides embodiments of environmentally acceptable fishing lines or fishing nets. Embodiments of the disclosed fishing line or net may comprise a degradable polymer having components derived from i) biomass sources, ii) protein, fatty acid or lipid sources, iii) microbial-based monomers and polymers, iv) agro-based monomers and polymers, v) sugar or starch based monomers and polymers, or combinations thereof, as well as fishing lines and net that further comprise an additive having components derived from i) polyol sources, ii) citrate sources, iii) fatty acid sources, iv) biomass oil sources, or combinations thereof. Some of the embodiments of the disclosed fishing lines or nets may have a suitable fiber core, while other embodiments of the disclosed fishing lines or nets are degradable over a predetermined period of time. The disclosed embodiments are preferred because of the low environmental impact of the disclosed fishing lines or nets when compared to, for example, well known synthetic polymer fishing lines or nets.

The present disclosure provides a braided twine (100) that includes a twine core (102), a braided sheath (106) configured around the twine core (102), and an intermediate film (104) configured between the twine core (102) and braided sheath (106) to bridge a gap between the twine core (102) and the braided sheath (106).

A production method for a headline sonar cable characterized by steps of: a. providing a first strength member (14); b. coupling to strength member (14) a conductor (122); c. forming a layer of polymeric material about the combination of strength member (14) and conductor (122) while ensuring that the conductor remains slack; d. forming a flow shield around the layer of polymeric material, thus forming an elongatable internally located conductive structure; and e. braiding a strength-member jacket layer (52) of polymeric material around the elongatable internally located conductive structure while ensuring that the conductor is slack when surrounded by the jacket layer (52). For another embodiment, an optical fibre is wrapped around the exterior of the layer of polymeric material within which is enclosed a braided conductor formed about the first strength member (14). Other embodiments employ further thermo-plastic layers and further sheaths and further conductors.

A braided rope includes a plurality of braided strands comprising twisted yarns. Each of the twisted yarns includes a blend of first fibers and second fibers. The first fibers are high modulus polyethylene (HMPE) fibers and the second fibers may be lyotropic polymer filaments, thermotropic polymer filaments, or polyphenylene benzobisoxazole fibers. The first fibers can have a creep rate of no more than 3.0×10.sup.−8 percent per second at 20° C. while subjected to a stress of 5.0 grams/dtex. The first fibers can have a creep rate of no more than 1.0×10.sup.−7 percent per second at 20° C. while subjected to a stress of 7.5 grams/dtex.

A tie down ratchet and strap includes, a ratchet shaft rotatably mounted in a ratchet body having a slot for receiving a wind-up strap therethough, a pair of ratchet wheels mounted on the ratchet shaft, a ratchet handle with a pawl engaging the ratchet wheels to rotate the ratchet shaft, a locking bar securing the ratchet wheels and ratchet shaft in position when the pawl is disengaged from the ratchet wheels, an anchor strap with a connector for securing the ratchet assembly to a first anchor point, and a wind-up strap including a non-metallic fabric strap with a braided metal outer cover extending continuously over the length of the non-metallic fabric strap.

Disclosed is a blended rope having an outer sheath (8) enclosing at least a strength member (7), the strength member (7) having high-strength synthetic fibers, the strength member (7) being a blended strength member (7) formed with a combination of ARAMID fibers and HMPE fibers, the blended strength member comprising a non-homogeneous distribution of the ARAMID and HMPE fibers, wherein the weight ratio of ARAMID to HMPE in the strength member (7) is preferably a minimum of 80:20.
