Abstract
The invention discloses an electromagnetic shielding tarpaulin, which comprises stainless steel metal fibers and polyester chemical fibers. Two fiber card slivers are drawn and blended into yarns, and the yarns are stranded and woven into the conductive high-strength electromagnetic shielding tarpaulin by using a twill weaving method. By repeated drawing of the conductive metal fiber card slivers and the high-strength low-elongation chemical fiber card slivers, the metal fibers and the chemical fibers are fully mixed uniformly and are consistent thoroughly; and weaving of the electromagnetic shielding tarpaulin is realized by processes of roving, spinning, stranding, twisting, spooling, quilling, warping and weaving.
Description
Technical field
The invention belongs to the electromagnetic protection field of prevention electromagnetic information leakage and electromagnetic pulse interference, particularly a kind of flexible blending electromagnetic shielding tarpaulin of electromagnetic shielding tent.
Background technology
At present domestic and international developed electromagnetic shield cloth mainly contains two types, and the one, at metallic conduction materials such as base cloth surface coating or electro-coppering, aluminium, nickel, make shielding cloth surface layer form continuous conduction face.The 2nd, adopt the metallic conduction fibers such as copper, aluminium, nickel carry out pure spin or with other fiber blends, make shielding cloth by showing to form even continuous conduction body to inner.Both comparatively speaking, the electromagnetic shield cloth production technology that applies or electroplate is simple, efficiency is high, cost is low, shortcoming is ABRASION RESISTANCE, folding resistance, poor durability, shield effectiveness decay is fast.Conductive fiber is pure spin or with electromagnetic shielding waring of cloth, folding resistance, the good endurance of other fiber blends, material even, inside and outside consistent, shield effectiveness is stable, shortcoming is that complex manufacturing, efficiency are low, cost is high, powerful index is low.From material self, copper easy-to-rust, aluminium is easy to wear, nickel cost is high.This two classes electromagnetic shield cloth is mainly for the radiation proof of human body and equipment, for the shielding clothing of physical protection and the radome of equipment protection etc., there is no for or be suitable for the shielding tarpaulin of electromagnetic information leakage and the outer electromagnetic pulse interference of paulin in the anti-paulin of electromagnetic shielding tent.So, study a kind of ABRASION RESISTANCE, folding resistance, durability, rust resistance good, shield effectiveness is stable, and powerful index is high, and cost is moderate, and the electromagnetic shielding tarpaulin material with tent attribute is one of important content of electromagnetic shielding tent research.
Summary of the invention
The object of the invention is to study a kind of ABRASION RESISTANCE, folding resistance, durability, rust resistance good, material is even, shield effectiveness is stable, powerful index is high, cost is moderate, the flexible blending electromagnetic shielding tarpaulin with tent attribute, for electromagnetic shielding tent shielding building enclosure provides a kind of performance indications reliable and stable Novel shielding tarpaulin material.
Technical scheme of the present invention is achieved in that and the present invention includes a kind of conductive metallic fiber and a kind of high-strength flatness chemical fibre, two kinds of fiber carded slivers, by drafting mixing spun yarn, adopt the strand of this yarn plying and use twill-weave weave to weave the high-strength electromagnetic shielding tarpaulin material of conduction.
Described electromagnetic shielding tarpaulin specifications and models are T/F29 * 2/29 * 2, the percentage by weight 50/50 of metal fibre and chemical fibre, 29 of yarn numbers, fabric width 127mm, mass area ratio 285g/m
2, through (latitude) to ultimate strength 1000N, shield effectiveness 45dB (450MHz, 950MHz, 3GHz, 6GHz).
The present invention adopts above-mentioned technological approaches, the conductive metallic fiber carded sliver and the high-strength flatness chemical fibre carded sliver be drafting repeatedly, metal fibre is fully mixed with chemical fibre, front and back are inside and outside consistent, again through rove, spun yarn, plying twist thread, winder, quiling, warping and weaving process, realize weaving of electromagnetic shielding tarpaulin.
Accompanying drawing explanation
Accompanying drawing 1 is process flow diagram of the present invention;
Below in conjunction with accompanying drawing, content of the present invention is described in further detail.
The specific embodiment
Shown in accompanying drawing, the present invention mainly comprises metal fibre 1, chemical fibre 2, and blended roving 3, blending spun yarn 4, plying twists thread 5, winder strand 6, whole footpath, quiling strand 7, twill shielding cloth 8.
When processing is weaved, adopt the stainless steel metal fibre carded sliver 1 and the terylene chemical fibre carded sliver 2 to carry out drafting, the number of times of drafting depends on 1 uniformity coefficient mixing with 2, after several drafting mixes, inside and outside blended fiber rove bar 3 uniformly before and after forming, rove bar 3 drawns and twisting form fine yarn 4, yarn 4 forms strand 5 through doubling twisting, strand 5 channels and collaterals cylinders form cylinder yarn 6, cylinder yarn 6 is after secondary winder, whole footpath, quiling form footpath, latitude strand 7, and strand 7 is through adopting 2/1 twill-weave weave to weave blending electromagnetic shielding tarpaulin 8.
Blending electromagnetic shielding tarpaulin of the present invention, due to preferred high conduction, anti-oxidant, rust stable stainless steel metal fibre, high-tenacity, corrosion-resistant, terylene chemical fibre cheaply, and according to the required powerful index of tent tarpaulin, the shield effectiveness index that tent reaches in advance, and weaving weaving process condition etc., determined the blending proportioning of metal fibre and chemical fibre, thereby guarantee the weavability of fabric, and the electromagnetic shielding tarpaulin weaving guarantees its shield effectiveness by metal fibre, by chemical fibre, guarantee its powerful index, predicable by both guarantees its ABRASION RESISTANCE, folding resistance, durability, rust resistance and moderate cost price.Structurally longitude and latitude intertwined point is few compared with plain weave weave for the twill-weave of selecting, and warp count is large, has reduced the abrasion of comprehensive reed to warp thread, and metal fibre comes off few, and the shielding cloth good conductivity that makes to weave, brute force is high, cloth cover is pliable and tough bright and clean.This electromagnetic shielding tarpaulin environmental suitability is strong, anti-oxidant, salt spray resistance, be suitable for high microthermal climate, shield effectiveness is reliable and stable.
