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 the domestic and international electromagnetic shielding cloth of developing mainly contains two types, and the one, at metallic conduction materials such as base cloth surface-coated or electro-coppering, aluminium, nickel, make the shielding cloth surface layer form the continuous conduction face.The 2nd, adopt metallic conduction fibers such as copper, aluminium, nickel carry out pure spin or with other fiber blends, make shielding cloth form even continuous conduction body to the lining by table.Both comparatively speaking, the electromagnetic shielding cloth production technology that applies or electroplate is simple, efficient is high, cost is low, shortcoming is ABRASION RESISTANCE, folding resistance, poor durability, the 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, even, the inside and outside unanimity of material, shield effectiveness are stable, shortcoming is that complex manufacturing, efficient are low, cost is high, powerful index is low.From material self, copper easy-to-rust, easy to wear, the nickel cost height of aluminium.These two types of electromagnetic shielding cloth are primarily aimed at the radiation proof of human body and equipment; Be used for the shielding clothing of physical protection and the radome of equipment protection etc., still needleless to 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 it is good to study a kind of ABRASION RESISTANCE, folding resistance, durability, rust resistance, 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
It is good to the objective of the invention is to study a kind of ABRASION RESISTANCE, folding resistance, durability, rust resistance; Material is even; Shield effectiveness is stable, and powerful index is high, and cost is moderate; Flexible blending electromagnetic shielding tarpaulin with tent attribute is 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 adopt the strand of this yarn plying and use the twill-weave weave to weave out the high-strength electromagnetic shielding tarpaulin of conduction material through drafting mixing spun yarn.
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 and chemical fibre are fully mixed; Before and after inside and outside consistent, again through rove, spun yarn, plying twist thread, winder, quiling, warping and weaving process, realize weaving of electromagnetic shielding tarpaulin.
Description of drawings
Accompanying drawing 1 is a process flow diagram of the present invention;
Below in conjunction with accompanying drawing content of the present invention is done further explain.
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.
Processing adopts the stainless steel metal fibre carded sliver 1 and the terylene chemical fibre carded sliver 2 to carry out drafting when weaving, and the number of times of drafting depends on 1 uniformity coefficient that mixes with 2; After drafting mixes for several times; Inside and outside blended fiber rove bar 3 uniformly before and after forming, rove bar 3 drawns form fine yarn 4 with twisting, and yarn 4 forms strand 5 through plying twisting; Strand 5 channels and collaterals tubes form tube yarn 6; Tube yarn 6 is behind the secondary winder, and whole footpath, quiling form footpath, latitude strand 7, and strand 7 is weaved out blending electromagnetic shielding tarpaulin 8 through adopting 2/1 twill-weave weave.
Blending electromagnetic shielding tarpaulin of the present invention; Because preferred high conduction, anti-oxidant, rust stable stainless steel metal fibre; High-tenacity, corrosion-resistant, terylene chemical fibre cheaply, and, confirmed the blending proportioning of metal fibre and chemical fibre according to the required powerful index of tent tarpaulin, shield effectiveness index that tent reaches in advance and weaving weaving process condition etc.; Thereby guarantee the weaving property of fabric; And the electromagnetic shielding tarpaulin of weaving out guarantees its shield effectiveness by metal fibre, guarantees its powerful index by chemical fibre, by both its ABRASION RESISTANCE of predicable assurance, folding resistance, durability, rust resistance and moderate cost prices.Structurally the longitude and latitude intertwined point is few than the plain weave weave for the twill-weave of selecting, and warp count is big, has reduced the abrasion of comprehensive reed to warp thread, and metal fibre comes off few, makes shielding cloth good conductivity, brute force height, the cloth cover weaved out 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.
