Embodiment 1

[0025] The aramid 1414 fiber uses Kevlar from DuPont of the United States, the cotton fiber is ordinary fine-staple cotton, and the conductive filament is a composite organic conductive filament with a polyester matrix of 22T-5-623.

[0026] The antistatic oil agent SN and water are formulated into a stable emulsion at a ratio of 1:10, and the emulsion accounts for 0.4% of the dry weight of the fiber, and is evenly sprayed on the aramid fiber 1414 fiber, and the aramid fiber 1414 fiber is pretreated for 24 hours. deal with.

[0027] In the opening and cleaning process, the above-mentioned pretreated aramid 1414 fiber and cotton fiber are evenly mixed according to the weight ratio of 6:4. Cotton machine and cotton cleaning machine are processed in four processes, using the principles of conventional fine cotton picking, time difference mixing, fine opening (combing needles, saw blades, sawtooth beater opening), low roll length and weight quantitative principles, and adding cott...

Embodiment 2

[0036] The experimental raw materials are as described in Example 1, and the process principles of each process are also the same, so it will not be repeated in this embodiment, and only different process parameter configurations will be described.

[0037]Mix the quaternary ammonium salt type antistatic oil agent SN and water in a ratio of 1:10 to make a stable emulsion, and spray evenly on the aramid fiber 1414 fiber with the emulsion accounting for 0.4% of the dry weight of the fiber, and put it on the machine after 24 hours of stacking spinning.

[0038] In the cleaning process, 80wt% aramid 1414 fibers are evenly mixed with 20wt% cotton fibers, and mixed sliver is made by carding machine. Its carding draw ratio is 90, card sliver basis weight is 20.06g / 5m, cylinder roller speed is 440r / min, licker-in roller speed is 970r / min, cover plate is 120mm / min, cylinder roller and licker-in roller distance is 0.15mm, cylinder roller The distance between the roller and the doffer r...

Abstract

The invention discloses a high-strength, flame-retardant and antistatic blended yarn and a production method thereof. The high-strength, flame-retardant and antistatic blended yarn is produced in the method comprising the steps that single yarns are formed by 60-80wt% of aramid fibers 1414 and 20-40wt% of cotton fibers in a blended mode through an opening and cleaning procedure, a cotton carding procedure, a drawing procedure, a roving procedure and a spinning procedure, wherein the lengths of the aramid fibers 1414 range from 35mm to 40mm, the line density of the aramid fibers 1414 ranges from 1.65dtex to 1.86dtex, the aramid fibers 1414 are pre-processed through antistatic oil, the lengths of the cotton fibers range from 25mm to 31mm, and the fineness of the cotton fibers ranges from 1.54dtex to 2dtex; finally, 0.5-5wt% of conductive filaments are merged into the single yarns in a winding and cabling procedure, and doubling and twisting are conducted. The high-strength, flame-retardant and antistatic blended yarn makes full use of high orientation and strong inter-chain bonding power of the aramid fibers 1414, good hygroscopicity of the cotton fibers and relatively low specific resistance of the conductive filaments, has the advantages of achieving high strength, flame retardance and resistance to static, and is particularly suitable for industrial textiles with the requirement for a special protection function.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a yarn and a production method thereof, in particular to a blended yarn with high strength, flame retardancy and antistatic properties and a production method thereof. Background technique [0002] With the development and progress of modern science and technology, high-tech textiles have been studied in depth and extensively. Various textile application fields have increasingly rich functional requirements for textiles, and the research and development of fiber products that integrate multiple functions has become a top priority. Conventional textile fibers, especially chemical fibers are not only mostly combustible or combustible materials, but also have high insulation properties. Considering the defects in these two aspects, in order to ensure the safety of practitioners in dangerous fields such as mining, fire fighting, ordnance, and to take into account the durability and com...
