Problems solved by technology

[0002] At present, blended yarn is yarn spun from two or more fibers, such as linen / cotton, wool / cotton, wool / linen / silk, polyester / cotton, polyester / wool, etc., through two different The fibers are spun into blended yarns, and these blended yarns have single performance and functions, and the application fields are limited. The existing blended yarns are mainly aimed at the strength of the blended yarns, the fine density of the fibers, the hardness of the blended yarns, The strength of blended yarns is improved, and the existing blended yarns are all blended between the original cotton, linen, wool, silk, and chemical fibers. The degree of improvement in the performance of blended yarns is extremely limited, and performance cannot be obtained. More superior blended yarns cannot be applied to wider application fields
[0003] It can be seen that the existing blended yarns have single performance and limited application fields, which cannot meet the needs of modern life and industrial production, and need to be further improved.

Embodiment 1

[0024] Please refer to figure 1 As shown, the aramid fiber and nickel-iron fiber blended yarn of the present invention comprises: 75-95 parts by weight of aramid and 5-25 parts by weight of nickel-iron fiber. Preferably, the aramid fiber and nickel-iron fiber blended yarn of the present invention comprises 90 parts by weight of aramid fiber and 10 parts by weight of nickel-iron fiber.

[0025] Preferably, the aramid fiber and ferronickel fiber blended yarn of the present invention comprises: 85 parts by weight of aramid fiber and 15 parts by weight of ferronickel fiber.

[0026] Preferably, the aramid fiber and ferronickel fiber blended yarn of the present invention comprises: 80 parts by weight of aramid fiber and 20 parts by weight of ferronickel fiber.

[0027] The preparation process of the aramid fiber and the nickel-iron fiber blended yarn of the present invention is mixed by a drawing process, wherein, the aramid fiber of the present invention adopts aramid fiber 1414,...

Embodiment 2

[0030] The specific steps of the preparation process of the aramid fiber and nickel-iron fiber blended yarn of the present invention are as follows:

[0031] Step A: cleaning and carding process, the aramid fiber of the present invention adopts aramid fiber 1414;

[0032] Step A1: Loosen the compressed aramid fiber 1414 into smaller fiber blocks or fiber bundles, so as to facilitate the smooth progress of mixing and impurity removal;

[0033] Step A2: Remove most of the impurities, defects and short fibers that are not suitable for spinning in the original pressed aramid 1414 fibers;

[0034] Step A3: Mixing the original aramid 1414 staple fibers of different compositions sufficiently and uniformly to stabilize the quality of the aramid 1414 fibers;

[0035] Step A4: A aramid 1414 fiber roll with a certain weight, length, uniform thickness and good shape is made.

[0036] Through the cleaning and carding process of this step, the aramid 1414 fibers are decomposed into a sing...

Abstract

The invention discloses a blended yarn of aramid fibres and nickel-iron fibres. The blended yarn comprises 75-95 parts by weight of aramid fibres and 5-25 parts by weight of nickel-iron fibres. The blended yarn of the aramid fibres and the nickel-iron fibres has good mechanical characteristics, relatively high breaking strength and relatively low elongation at break, meets urgent needs, on radar canopy, in space flight and aviation, has excellent flame resistance and excellent heat resistance and stable chemical property; the aramid fibres can be corroded by most of acidic chemicals while mechanical properties of the aramid fibres are hardly affected; and moreover, the blended yarn of the aramid fibres and the nickel-iron fibres has radiation resistance, durability, excellent wear resistance, corrosion resistance and washing resistance, so that strength of the blended yarn still can be kept to be 80% or higher of the original strength of the blended yarn even the blended yarn is worn, chemically corroded and washed by many times.

Description

technical field [0001] The invention relates to the technical field of preparation of blended yarns, in particular to a blended yarn of aramid fibers and nickel-iron fibers and a preparation process thereof. Background technique [0002] At present, blended yarn is a yarn spun from two or more fibers, such as linen / cotton, wool / cotton, wool / linen / silk, polyester / cotton, polyester / wool, etc., through two different Fibers are spun into blended yarns, and these blended yarns have single performance and function, and their application fields are limited. The strength of the blended yarn is improved, and the existing blended yarns are all blended among the original cotton, hemp, wool, silk and chemical fibers. The degree of improvement in the performance of the blended yarn is extremely limited, and the performance cannot be obtained A more superior blended yarn cannot be applied to a wider range of applications. [0003] It can be seen that the existing blended yarns have sing...
