Description
Technical field
The invention belongs to functional textile fabric technical field, and in particular to a kind of shielding fabric of livewire work, this hair
The bright preparation method for further relating to the shielding fabric.
Background technology
Ultra-high-tension power transmission line has been widely used in because it has the characteristics that remote, Large Copacity and low-loss conveying are electric
In power system.Due to consideration that the problem of safety work, generally, electric operation is using power-off operation.It is but disconnected
Electric operation can cause large-area power-cuts, cause larger economic loss, meanwhile, before power-off and power transmission, sufficient standard will be done
It is standby, add the manpower and materials cost of power industry and some other losses.
In recent years, increasing power department starts to use livewire work both at home and abroad, so can be in power network not by shadow
In the case of sound, checked and repaired to repairing point.Livewire work is that a kind of excessive risk, difficulty be big, the operation of technical sophistication
Mode.What livewire work preferentially to be considered is security, and shielding clothing is exactly necessary protective gear, when using equipotential live line work
When, operating personnel must wear a full set of screening clothing, using the hard ladder of insulation, insulation chair lift and slide rail etc. into high potential area, and
Operation is carried out under the conditions of high-voltage conductor equipotential link.The quality of livewire work screening clothing directly concerns life security.According to
The requirement of operating environment, livewire work screening clothing should have the spy of high conductivity, high electromagnetic wave shielding, anti-flammability and durability
Point.
At present, the enterprise of China's production livewire work screening clothing is considerably less, it can be seen from the investigation of correlation, livewire work screen
Covering clothes mainly has two kinds of fabrics, a kind of to be formed by metallic fiber, wool, silk blending, although such fabric has electricity
Performance and anti-flammability, but fire resistance is general, low intensity, and cost is higher；Another kind is mixed by metallic fiber and fire resistance fibre
Spin what is formed, although the fabric fire resistance is good, intensity is high, fabric Boardy Feeling, hygroscopicity are poor, and wearing comfort is bad.
In view of above present situation, design a kind of high shielding, low resistance, high current-carrying capacity, high intensity, permanent fire retardant, take
Comfortable new livewire work screening clothing fabric meets actual demand.
The content of the invention
It is an object of the invention to provide a kind of shielding fabric of livewire work, the shielding fabric is applied to exchange 110KV
Livewire work in~750KV and direct current ± 500KV voltage class line projects.
It is a further object of the present invention to provide the preparation method of above-mentioned shielding fabric.
The technical solution adopted in the present invention is that a kind of shielding fabric of livewire work, the shielding fabric is by through weft yarn
It is interwoven with the copper wire composite yarn with warp and weft interweaving；Include following components by mass percentage through weft yarn to form：Metal
Fiber 30%~60%, aramid fiber 15%~30% and polyacrylic and polyester fiber 10%~55%, above constituent mass percentage it
With for 100%.
The features of the present invention also resides in,
The grid size that copper wire composite yarn interweaves is 2cm~5cm × 2cm~5cm.
Line density through weft yarn is 13tex × 2~37tex × 2.
It is any one in 1/1,2/1,2/2,3/1 twill-weave through weft yarn institutional framework.
Ground plane material mass area ratio is 200g/m2~400g/m2。
Another technical scheme of the present invention is the preparation method of the shielding fabric of the livewire work, specifically
Step is as follows：
Step 1, spin：Weigh respectively by mass percentage：Metallic fiber 30%~60%, aramid fiber 15%~30%
With polyacrylic and polyester fiber 10%~55%, above constituent mass percentage sum is 100%；Aramid fiber and polyacrylic and polyester fiber is former
Material uniformly after mixing, successively after scutching cotton, cotton carding, adds metallic fiber, then by drafting, rove, spun yarn, winder and yarn steaming
Blending is into warp thread and weft yarn；
Step 2, warping：On warping machine beam of a loom to step 1 in warp thread carry out warping；
Step 3, looming：Warp thread on warping machine beam of a loom is passed through into menopause tablet, heald and reed by rule；
Step 4, weave：The copper wire composite yarn that warp thread in weft yarn and step 3 and longitude and latitude interweave is made into face using loom
Material；
Step 5, post-process：By in step 4 fabric carry out fabric inspection, then collated, tentering, sizing, clot be into
Product fabric.
The characteristics of another technical scheme of the invention, also resides in,
In step 4, the technological parameter of loom is：Speed is 200r/min~260r/min, back beam height be 980mm~
1020mm, heald level time are 300 °~330 °.
In step 5, tentering and setting temperature are 160 DEG C~180 DEG C.
The beneficial effects of the invention are as follows：
1. the present invention is by the resistance to shielding fabric, shield effectiveness, blowout current, flammability, washing fastness and takes
The analysis and research of comfortableness, and combine standard GB/T/T6568-2008《Livewire work shielding clothing》It is required that Rational choice
The component of raw material, optimal fiber compatibility program, fabric specification, and weaving, final finishing technical matters are devised, developing has
Low resistance, high shielding, permanent fire retardant, the multi-functional livewire work such as comfortable shields fabric when taking；
2. the copper wire composite yarn of excellent electric conductivity is woven into shielding fabric by the present invention, mesh current logical circulation road is formed it into
Footpath, the current-carrying capacity of clothes is improved, ensure the security of equipotential live line work；
3. the shielding fabric of the present invention not only improves the outward appearance and wearing comfort of the existing powered screening clothing fabric in China,
And every safety index is more excellent, more efficient can prevent electric field in high-tension line, electric current and induced electricity from being made to human body
Into harm, suitable for exchange 110KV~750KV and direct current ± 500KV voltage class circuit livewire work；
4. in process is weaved, using photo-electric menopause device, solve to stop caused by metallic fiber comes off
Car phenomenon, weaving efficiency is improved, technique protects filling yarn using the technology of " the short back rest, small tension receiving coil, small opening " on machine
It is not damaged.
