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.

Small Diameter, High Strength, Low Elongation, Creep Resistant, Abrasion Resistant Braided Structure
20220372700 · 2022-11-24 ·

A braided structure that includes a core and a sheath is provided. The core includes a yarn formed at least in part from an aromatic polymer (e.g., an aromatic polyester/liquid crystalline polymer or an aramid polymer), and the sheath, which includes a plurality of ultra high molecular weight polyolefin yarns, is braided around the core. The sheath has an overall diameter ranging from about 60 micrometers to about 650 micrometers. Despite its small diameter, the braided structure can be creep resistant and abrasion resistant while at the same time exhibiting low elongation, a high load at break, and high stiffness. The braided structure can be used in medical applications such as sutures, load bearing orthopedic applications, artificial tendons/ligaments, fixation devices, actuation cables, components for tissue repair, etc.

Seed rope
11432453 · 2022-09-06 ·

A biodegradable seed rope having predetermined positioning of seeds along with nutrients is disclosed. The rope may be made of but is not limited too any organic, biodegradable or water-soluble substantial grass/paper-based composition material. Additionally, the rope is infused with organic fertilizer, nutrients, and minerals to nurture the soil and support the growth of the seeds. The seeds are spaced apart equally along the seed rope. The spacing of the seeds are determined by the type of seed that is placed within the rope.
