Abstract

The invention discloses a production process of metal microfilament for weaving. The production process comprises the following steps: a. selecting metal precursor as a raw material; b. sending the metal precursor into a heavy wire-drawing machine for drawing; c. sending the metal wire subjected to heavy wire-drawing into a first annealing furnace for annealing; d. sending the metal wire subjected to the first annealing to the wire-drawing machine for drawing; e. sending the metal wire subjected to drawing into a second annealing furnace for annealing; f. sending the metal wire subjected to the second annealing into a micro drawing-machine for drawing; g. sending the metal wire subjected to the micro drawing into a third annealing furnace for annealing; g. sending the metal wire subjected to the micro drawing into a third annealing furnace for annealing; and i. immersing the metal wire wound on the spool into oil. The metal microfilament produced by three drawings and three annealings has diameter up to 0.035mm, good surface finish, high tear strength, good flexibility, and elongation rate reaching 28%-33%. In addition, the metal microfilament is immersed into dimethyl silicone oil after the third annealing, so as to increase the viscosity of the metal microfilament, and facilitate paying off by the users.

Description

technical field [0001] The invention relates to a production process of metal microwires, in particular to a production process of metal microwires widely used in the textile industry. Background technique [0002] Metal microwires are made of stainless steel wires, which have good effects of electromagnetic isolation, radiation protection, corrosion resistance, and memory setting. They have been widely used to make clothing, gauze scarves, tablecloths, decorative cloths, etc., and are loved by people; however, Metal microwires are used in clothing fabrics, which have very strict requirements on the flexibility, elongation, and tear strength of metal microwires. The current production process of metal microwires is rough, and the produced metal microwires have the following deficiencies: at: [0003] 1. The wire diameter of the metal microwire is too thick, generally above 0.05mm, and the flexibility is poor; [0004] 2. The elongation rate of metal filaments is low, gener...
