Abstract

The invention discloses an Ni-Mn-Ga alloy fiber capable of being used for textiles and belongs to the field of textile fibers. The component of the alloy fiber is Ni50+xMn23+yGa[27-x-y] (x is larger than or equal to 2 and smaller than or equal to 4, and y is larger than or equal to 2 and smaller than or equal to 4). The Ni-Mn-Ga alloy fiber is prepared by the following steps: carrying out burdening according to nominal compositions, under the protection of vacuum introducing argon gas, smelting the nominal compositions into an alloy ingot by utilizing an electric arc furnace, carrying out heat treatment, utilizing a Taylor glass coating method, and carrying out water cooling to prepare the alloy fiber. The prepared alloy fiber is of a martensite structure at normal temperature, the diameter is between 5 microns and 100 microns, and the length can reach 5-200cm. The Ni-Mn-Ga alloy fiber is relatively large in tensile strength, can arbitrarily bend and deform at the normal temperature, has the softness similar to that of ordinary fiber threads used by the textiles and can be used as the textile fibers to be woven into cloth or knitted in a fabric. Clothing knitted by utilizing the Ni-Mn-Ga alloy fiber has the functions of radiation resistance, magnetic shielding and the like, is comfortable and is liable to wear, and thus the problem that the demands for clothing softness cannot be met due to overlarge rigidity of two of iron wires and stainless steel wires which are metal wires with the shielding action in the clothing in the textile fiber field is solved.

Description

【Technical field】 [0001] The invention belongs to the field of textile fibers, and in particular relates to a Ni-Mn-Ga alloy fiber which can be used for textiles. 【Background technique】 [0002] At present, with the improvement of people's living standards, the requirements for clothing are getting higher and higher. Due to the needs of work, etc., people's daily clothes should not only be comfortable, but also have functions such as radiation protection and magnetic shielding. But now clothes with functions such as radiation protection and magnetic shielding are generally made of special composite fabrics based on metal wires embedded in the clothes. The metal wires used are generally iron or stainless steel microwires. Such as Chinese patent CN104746194A "A kind of electromagnetic shielding and anti-radiation home textile fiber material and its fabric and application". Because the iron wire or stainless steel microwire is too rigid, the softness is far from meeting the n...
