Kuraray Co., Ltd.
Kuraray Co., Ltd. has developed a new specialized compound yarn made with a proprietary core-sheath construction for use in making rope. Sale of the new product will commence on May 1, 2008.
The product possesses a proprietary core-sheath construction created through a specialty compound consisting of continuous polyester filament core thread and green, sheath thread of spun-dyed KURALON spun yarn. The combined features of the continuous polyester filament, which demonstrates high tensile strength, low elongation, and dimensional stability, and KURALON spun yarn, which has an easy feel for handling comfort and demonstrates high weather resistance, form a well-balanced compound material. KURALON spun yarn sheath thread is dyed using a spin-dye process-a method superior to standard thread-dying methods-that contributes to excellent color fastness able to withstand washing and sun exposure. Another feature of spun-dyed thread is that color from the dyed materials does not easily transfer onto substances with which it comes in contact.
Although Kuraray's previously released rope types using both KURALON spun yarn and a KURALON-polyester spun yarn mix were widely accepted, there was a market demand for higher tensile strength and lower elongation properties in onshore-use ropes. Responding to this need, Kuraray drew on its unique accumulation of technologies and command of materials to develop a third-generation rope type.
As a provider of a high-quality lineup of ropes, Kuraray will diligently work to expand and develop rope applications in the market.
