preparation example Construction

[0032] The preparation method of this novel cut-resistant yarn uses high-strength and high-count tungsten filament yarn as the core yarn, wraps the core yarn with wrapping fiber / yarn, and weaves it into a new cut-resistant yarn through a spinning process Wherein, the number of the core yarn is 3-250tex, the tungsten yarn accounts for 20%-80% of the total weight of the novel anti-cut yarn by weight percentage, and the spinning process is air-jet vortex spinning, One of various processing methods such as friction spinning and rotor spinning. The number of the core yarn is 10-230, preferably 30-200, more preferably 50-150; more preferably 80-120; the tungsten yarn accounts for the total weight of the novel cut-resistant yarn by weight percentage 25%-70%, preferably 30%-60%, preferably 35%-50%, more preferably 40%-45%.

[0033] The tungsten yarn used in the present invention is pure tungsten wire, tungsten wire etched on the surface, boron-carbon doped tungsten wire, aluminum oxi...

Abstract

The present invention discloses a novel cut-resistant yarn and production method of cut-resistant articles of the novel cut-resistance yarn; the novel cut-resistant yarn is woven by: using a high-strength high-count tungsten filament yarn as a core yarn, covering the core yarn with wrapping fiber/yarn, and spinning; wherein, core yarn count is 3-250 tex, and the tungsten filament yarn is 20-80% by weight of total weight of the novel cut-resistant yarn. The cut-resistant articles made with the novel cut-resistant yarn have good cut resistance, electromagnetic shielding performance, self-extinguishment, flame retardancy, tolerance to high temperature, flexibility, wearing comfort and good processibility, and the production method is simple, convenient to operate and low in production cost and has a promising market application prospect.

Description

technical field [0001] The invention relates to the technical field of safety protection products, in particular to a novel cut-resistant yarn and a preparation method of the cut-resistant product. Background technique [0002] my country's industrial production is booming, and people's awareness of paying attention to the working environment and protecting their own safety and health has gained a new understanding and improvement. Especially in some heavy industry production enterprises, the hands of employees are more frequently in contact with hard materials such as steel and iron, and are vulnerable to injury. Cut-resistant gloves are the last risk control measure for hand protection. Personnel engaged in extreme mechanical work, high-cutting risk jobs, steel plate finishing, and handling metal products should wear them. [0003] Cut-resistant gloves, cut-resistant arm guards, and cut-resistant backpacks are usually prepared with cut-resistant yarns. U.S. Patent (USP6...
