Problems solved by technology

Due to the high manufacturing conditions and high price of metal fibers, and the content of metal fibers in metal fiber blended yarns can neither be too much nor too little, it is necessary to ensure that the content of metal fibers in the yarn is controlled within a reasonable range of 1.5-2.5%. The signal is completely blocked, and if it is less, it will not have the effect of signal interference. At the same time, the production process requirements of metal fiber blended yarn are also very different from those of ordinary yarn. Therefore, a method that can be used in production is easy to implement and easy to operate. The production method of successfully producing qualified metal fiber blended yarn is something that people are in urgent need of at present.

Embodiment 1

[0016] A production method of metal fiber blended yarn, the raw material metal fiber is stainless steel fiber, the specification is 38-41mm, 6g / mm, the textile fiber is cotton type polyester, the specification is 1.5D*38mm;

[0017] The cotton-type polyester is rolled and carded into strips, and the cotton-type polyester strips are drawn with stainless steel fiber strips. The weight content of stainless steel fibers after drawing is 3%; after that, the combined strips are shredded, loosened, and cleaned Rolling, carding and drawing, shredding, opening, cleaning, rolling, carding and drawing can be repeated 3 times. The cotton-type polyester and stainless steel fibers in the sliver are all mixed. Needle-type beater, and then the metal fiber blended yarn is obtained through air-spun spinning, the weight unevenness of the metal fiber blended yarn is less than 5%, the twist is 32-42 turns / 10cm, and the twist unevenness is less than 8%. The weight content of stainless steel fibers ...

Embodiment 2

[0019] A production method of metal fiber blended yarn, the raw material is metal fiber is silver fiber, the specification is 38mm, 6g / mm, the textile fiber is cotton, the specification is more than 33mm, 1.54-1.18dtex;

[0020] The cotton is plucked, loosened, cleaned and rolled, and carded into slivers, and the cotton sliver and silver fiber sliver are drawn, and the weight content of the silver fiber after drawing is 2.9%; Shredding, opening, clearing into rolls, carding and drawing, mixing the inner cotton and silver fiber evenly, using comb-type beating hands when opening and clearing, and then making metal fiber blends by air spinning Yarn, the obtained metal fiber blended yarn has a weight irregularity of 4.2%, a twist of 40 turns / 10cm, a twist of 7%, and a weight content of stainless steel fibers of 2.2%.

Abstract

The invention discloses a method for producing metal fiber blended yarn. First, drawing of textile fiber rods and metal fiber rods is carried out; the proportion by weight of the metal fiber is 2.9%-3.2% after the drawing; and then the metal fiber blended yarn is formed through the process of tearing up, opening, scutching and coiling, cotton carding, drawing and spinning of the drawn textile fiber rods and metal fiber rods. The method can be completely applied to production, and is convenient in application and easy in operation; metal fibrous raw materials are not liable to fall off during the production, and the content of the metal fiber is easy to control; and the produced metal fiber blended yarn has the advantages of high strength, low yarn unevenness, less hairiness, less yarn faults and good shielding performance, and meets the requirements of garment fabrics.

Description

technical field [0001] The invention relates to blended yarn technology, in particular to a production method of metal fiber blended yarn. Background technique [0002] In recent years, with the continuous improvement of construction level, clothing fabrics with shielding effect have become more and more important in national defense construction and civilian production, and have been used more and more. There is also increasing demand for metal fiber blended yarns for the production of clothing fabrics with shielding effects. Due to the high manufacturing conditions and high price of metal fibers, and the content of metal fibers in metal fiber blended yarns can neither be too much nor too little, it is necessary to ensure that the content of metal fibers in the yarn is controlled within a reasonable range of 1.5-2.5%. The signal is completely blocked, and if it is less, it will not have the effect of signal interference. At the same time, the production process requirement...
