Problems solved by technology

[0002] At present, the flame-retardant yarns on the market are usually made of pure fiber or blended with flame-retardant acrylic and cotton fibers. The flame-retardant performance of this type of yarn can also meet the national flame-retardant standards, but there are the following obvious disadvantages: 1. Blended yarns Low strength, 2. Pure fiber yarn has poor wearing performance and poor air permeability. 3. This kind of yarn has low thermal insulation performance, so it is not suitable for protective occasions with high strength requirements

Abstract

The invention provides inflaming retarding wool cross-blended yarn and a production method thereof. The inflaming retarding wool cross-blended yarn is characterized by comprising the following components by weight: 20 to 50 % of wool fiber, 20 to 50 % of inflaming retarding nitrile polyvinyl chloride fibre, 10 to 40 % of aramid and 1 to 5 % of conductive fiber. As the wool, the fibre aramid and the inflaming retarding nitrile polyvinyl chloride fibre are easy to produce static electricity, the yarn reduces the static electricity phenomenon through two aspects: the first one is to mix a certain proportion of conductive fiber, and the second one is to carry out pretreatment on the raw materials before the spinning, adding wool oil, and still standing to carry out well-being process. During the preparing process, the technology condition of each process is strictly controlled; the temperature and the relative humidity of cotton carding, drawing, roving and spinning processes are controlled; the serious static electricity problems of the wool, the inflaming retarding acrylon and the aramid during the spinning can be well solved; the strong rigidity of the aramid fibre can be overcome; the yarn quality is ensured.

Description

technical field [0001] The invention relates to a blended yarn and a production method thereof. Background technique [0002] At present, the flame-retardant yarns on the market are usually made of pure fiber or blended with flame-retardant acrylic and cotton fibers. The flame-retardant performance of this type of yarn can also meet the national flame-retardant standards, but there are the following obvious disadvantages: 1. Blended yarns Low strength, 2. Pure fiber yarn has poor wearing performance and poor air permeability. 3. This kind of yarn has low thermal performance, so it is not suitable for protective occasions with high strength requirements. Contents of the invention [0003] The object of the present invention is to provide a kind of high flame-retardant wool blended yarn and its production method, so as to overcome the above-mentioned defects existing in the prior art. [0004] The flame-retardant wool blended yarn includes the following components in weight...
