Abstract

The invention provides a preparation method of anti-cutting yarn. Two high-strength polyester filaments or ordinary polyester filaments are plyed and twisted, and then twisted and coated with ordinary glass fiber filaments or basalt fibers to form a core yarn. , On the basis of the above core fiber, the outer layer is covered with high-strength nylon or high-strength polyester filament or high-strength nylon and spandex as the outsourcing fiber to make a cut-resistant yarn. The core yarn provides the skeleton of the cut-resistant yarn, the spandex provides comfortable elasticity, and the outer covering yarn provides toughness resistant to direct cutting, which can be used in textiles including fabrics, gloves, sheaths, aprons and other fields. The present invention adopts conventional fiber varieties as the core yarn, rationally configures the twist of the yarn and the distribution and proportion of fibers, so that the yarn or textiles can reach different anti-cutting levels and the highest anti-cutting level, greatly reducing the production cost, and the cutting resistance is stable. And the yarn feels comfortable.

Description

technical field [0001] The invention relates to a method for preparing a yarn, in particular to a method for preparing a low-cost anti-cut yarn. Background technique [0002] Cut-resistant textiles around the world use expensive high-strength and high-modulus fibers to achieve the purpose of cutting resistance. Such as aramid 1414, high-strength high-modulus polyethylene fiber, etc. In order to reduce the price, aramid 1414 is blended with other fibers, or high-strength high-modulus polyethylene is combined with other fibers, or on the basis of the above, glass fiber, or steel wire and other materials are added. Such as: Chinese patent CN104862843A discloses a kind of ultra-high molecular weight polyethylene core-spun yarn and its preparation method; Chinese patent CN104814549A discloses a preparation method of ultra-high molecular weight polyethylene cotton type cut-resistant gloves; A cut-resistant glove is disclosed. The cut-resistant glove is composed of two layers ins...
