Description
Technical field
The invention belongs to fabric preparation field, and in particular to a kind of preparation method of novel radiation-proof fabric.
Background technology
The fast development of modern high technology product and electric equipment, the life to people, work offer convenience, efficiently with
While happy, many harm are also brought, a kind of invisible, impalpable new pollution sources cause all over the world
Concern, this is the electromagnetic radiation that people are referred to as " stealthy killer ", and it has become dirty after water pollution, atmosphere pollution and noise
The fourth-largest pollution sources of human health are influenceed after dye.Put down in micro- magnetic field that electromagnetic radiation mainly influences inside of human body tissue by magnetic field
Weighing apparatus, and then influence the health of people.Energy derived from electromagnetic radiation depends primarily on the height of electromagnetic radiation source frequency, and one
As frequency values it is higher, caused energy is also bigger, and the extent of injury of human body is consequently increased.Therefore, possesses anti-electromagnetism
The clothes of radiation function have become today's society people and pursue one of textile of healthy living, and with the development of society
Also increasingly attract widespread attention.
The method of common raisings fabric shielding electromagnetic wave efficiency mainly has four kinds at present, be respectively use spraying coating process,
Coating process, metallic fiber and pure cotton fiber blended weave and nano silver fibre are primary raw material.Radiation-proof fabric is technically

Specific target group carry out fabric selection and Design modelling, Radiation proof dress also need to the support of some product technology aspects.
Many exposure suits can only be used as overcoat to wear under normal circumstances now, it is impossible to wear next to the skin, because containing salt in sweat,
Direct contacting metal fiber, easily chemically reacts, and causes the corrosion to radiation proof metallic fiber, destroys anti-radiation effect,
It is coarse plus fabric feel, be not suitable for underwear；Metal ion shell fabric in the case of washing or rubbing frequently, can often subtract
Weak shield effectiveness, so can not frequently wash；Also it can only hang or keep flat during storage, it is impossible to folding and weight, otherwise can cause
Radiation-proof effect weakens.In addition, there is certain difficulty in radiation-proof fabric, on dyeing and finishing technique so fabric color is also relatively more single
Adjust.These problems all limit the style and aesthetics of Radiation proof dress to a certain extent, therefore also necessarily limit this kind of
The fast development of product.The good news is many domestic enterprises are all actively carrying out the lasting research of correlation technique now, and carry out
Industrial chain extension, have from fabric design to end product and set foot in, this would be beneficial for the progress of technology.
The content of the invention
Goal of the invention：In order to solve the deficiencies in the prior art, the invention provides a kind of preparation of novel radiation-proof fabric
Method.
Technical scheme：A kind of preparation method of novel radiation-proof fabric, comprises the following steps：
(1) selection of raw material：Silver fiber is primary raw material, and it is in silver gray, and fiber dimensious are 1.5D × 45mm；Nano Silver
Fiber, it is silvery white in color, and fiber dimensious are 1.5D × 38mm.
(2) weave：Using the needle point method in non-woven processing method：Shredding --- --- combing --- lapping to cotton；Its
In：Silver fiber and nano silver fibre are weighed into weight respectively according to a certain percentage, it is uneven in order to avoid being mixed on opener,
Manually mixed in advance；In addition to carrying out artificial mixing, after networking, using the web of layer 2-3, one is superimposed upon
Rise, reduce the difference of the radiation-proof effect on monoblock pieces of cloth to greatest extent；Carried out instead on fiber using the pricker of needing machine
The cloth into certain performance is reinforced originally fluffy web in multiple puncture, and this cloth is by the obvolvent between fiber and fiber and squeezes
Press and formed.
(3) fabric is compound：The front of fabric is made of Pure Cotton Fabric Printing cloth, this calico of pure cotton makees the reverse side of fabric, and radiation proof is non-
Weaving pieces of cloth are placed on centre as sandwich layer, and three shell fabrics are carried out into quilting using DH-3 computer quilters；According to the chi of quilter
Very little, the specification of upper and lower two shell fabric at least needs 1m × 1m, then selects the grain pattern of quilting on computers, selects rhombus grain pattern to set
Determine machine, upper and lower two shell fabric and middle radiation-proof fabric are fixed；The preferably non-woven pieces of cloth of radiation-proof effect are entered
Row quilting, the nexine of pure cotton cloth can be worn next to the skin.
As optimization：In laid process, web is pressed with wooden stick during production, prevents web to be adsorbed onto on deflector roll.
As optimization：Also need to carry out acupuncture after fiber networking, when web is introduced into needing machine, it is entered with traction cloth
Row traction.
As optimization：Traction cloth leads web to be passed through among upper and lower spiked roller, and thorn up and down is first entered into web
During roller, feeding is helped with Handball Association.
Beneficial effect：Novel radiation-proof fabric in the present invention changes the sprayed metal layer on fabric in the past, uses metal
Fiber and general fibre blending resultant yarn, then carry out woven radiation proof theory.Select with anti-electromagnetic radiation, resist on raw material
The silver fiber of the performances such as bacterium deodorization and other fibers, are mixed by a certain percentage, are made Radiation-proof nonwovens piece, then with two
Non-woven pieces of cloth are clipped in the middle by layer light and thin fabric, and individual layer shape fabric is stitched into by quiltmg piocess.Suture was both protected
Radiation-proof nonwovens pieces, form decorative pattern, improve the stylishness of fabric, this is also this radiation-proof fabric again
Important breakthrough.The radiation-proof fabric being consequently formed act not only as overcoat dress, can also underwear wear next to the skin.Because have
The protection of suture, the washability of fabric is not only increased, and will not weaken its radiation-proof effect after washing.The fabric is not only
The comfortableness of radiation-proof fabric can be improved, and is decreased on production cost so that masses can receive.
Since it is considered that different applicable crowds, the radiation-proof effect that its needs reaches is also different, so the present invention adopts
It with different raw material mixing ratios, can both reach different radiation-proof effects, can have certain reduction in cost again, so
Fabric could be received by most people.The use range of current radiation-proof fabric is smaller, is used primarily on maternity dress, but
The fact is, the environment of people's life grows on trees radiation, and not only pregnant woman will carry out radiation proof protection, and common people are also required to appropriate
Radiation proof is protected.For example the liner of garment pocket is made of Radiation-proof nonwovens piece, so mobile phone, which is placed in pocket, to drop
Injury of the low electromagnetic to body, will not mask mobile phone signal again；The application of radiation-proof fabric has progressively popular, popularization
The trend of change, it can touch life, many aspects of work.
The specific advantage of the present invention is as follows：
(1) when preparing radiation proof pieces of cloth using nonwovens process, silver fiber and nano silver fibre mixing must be ensured
Uniformly, the radiation-proof effect of fabric otherwise can be caused unbalanced.The non-woven pieces of cloth worked it out using needle point method are soft, non-
Often it is adapted to do wearing fabric and auxiliary material, the number of acupuncture has an impact electromagnetic shielding value, with the increase of acupuncture number, electromagnetic screen
Cover value and first subtract and increase afterwards, so radiation-proof effect is optimal twice for acupuncture.
(2) it is compound to radiation-proof fabric progress using quilting technology, quilting grain pattern, top layer can be selected according to the purposes of fabric
Fabric and nexine fabric, surface layer fabric can arbitrarily select in the existing fabric in market, nexine fabric selection pure cotton cloth, change
Conventional radiation-proof fabric dyeing is difficult, can not wash, be not suitable for the shortcomings that underwear.Improve radiation-proof fabric stylishness,
Washability and comfortableness, this is an important breakthrough of radiation-proof fabric.
(3) using silver fiber as primary raw material, value-added content of product is improved, because silver fiber is not only with extraordinary
Radiation-proof effect, and the function such as also good antibacterial and deodouring, antistatic, it is difficult that radiation-proof fabric, which integrates these performances,
Can be valuable.But the price of silver fiber is relatively expensive, it is relatively inexpensive but have a small amount of radiation proof work(thus to mix part of price
The nano silver fibre of energy, the cost of radiation-proof fabric is reduced with this.Find by cost accounting, made with this radiation-proof fabric
The cost of clothes is no more than 150 yuan, and the price of in the market exposure suit is typically in 200-1000 members, by contrast
Price has larger difference, and the fabric is especially suitable for general population's use, for fabric developer, will obtain considerable profit
Profit.
(4) Radiation-proof nonwovens piece can do maternity dress by quilting, can also be used as the auxiliary material of business suit, can be with
In the different parts of clothes, selective does some radiation-proof effects, as mobile phone is often mounted in coat pocket or trousers by man

Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, so that the technology of this area
Personnel can be better understood from advantages and features of the invention, so as to make apparent boundary to protection scope of the present invention
It is fixed.Embodiment described in the invention is only part of the embodiment of the present invention, rather than whole embodiments, based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Embodiment
The selection of 1 raw material
Silver fiber is the primary raw material used in the present invention, and it is in silver gray, 1.5D × 45mm.Silver fiber is in polymer table
Plate one layer of fine silver and obtain fiber in face.After with silver fiber, mobile phone is wrapped up, mobile phone has been perceived less than any signal, so silver fiber
Really there is good electro-magnetic screen function；In addition it also has good antistatic effect, and he can be eliminated rapidly on clothing because rubbing
Wipe and caused electrostatic, make one to feel the comfort of no electrostatic.Moreover, silver fiber also has certain antibacterial and deodouring work(
Can, in the environment of warm moist, silver ion has very high bioactivity, so being so easy to combine with other materials, allows
The protein coagulating of bacterium, prevent it from breathing, so as to play the effect of antibacterial.Silver fiber has many good features,
But price is sufficiently expensive and unstable, its price changes with the variation of market silver valency, the silver fiber 1700 used in the present invention
Member/kg, the Cost Problems of the price relation of silver fiber to radiation-proof fabric.
Another raw material that the present invention uses is nano silver fibre, and fiber dimensious are 1.5D × 38mm.Nano silver fibre is
Ultra-fine silver particles are added in fiber forming process and realize functional fibre.In performance and silver fiber have it is certain it is similar it
Place, but really radiation-proof effect is not as good as silver fiber, and mainly the content of institute's argentiferous is different in the fiber, and nano silver fibre
Middle silver-colored content is less, so also there is larger difference in color, silver fiber is in silver gray, and nano silver fibre is then partial to
White.Because the content of silver is less, so the price of nano silver fibre is relatively low, only 30 yuan/kg, this is to reducing radiation proof face
The cost advantages of material.
2 preparation methods
The instrument and equipment that present invention research is used has the high accurate electromagnetic detection instrument of balance, EMD-2G, YBG343-110 pins
Thorn machine etc..Using the needle point method in non-woven processing method, the main flow that needle point method prepares Radiation-proof nonwovens piece is " to open
Pine --- --- combing --- lapping to cotton ".Silver fiber and nano silver fibre are weighed into weight respectively according to a certain percentage, in order to
Avoid mixing on opener uneven, manually mixed in advance.It is uneven in order to prevent from mixing, cause pieces of cloth radiation proof to be imitated
Fruit is different, in addition to carrying out artificial mixing, after networking, using the web of layer 2-3, is superimposed, can be maximum
Reduce to limit the difference of the radiation-proof effect on monoblock pieces of cloth.Puncture repeatedly is carried out on fiber using the pricker of needing machine
By originally fluffy web reinforcing into the cloth of certain performance, the obvolvent and extruding that this cloth is leaned between fiber and fiber completely,
The pieces of cloth produced using needle point method have certain strength, soft, good permeability, improve to a certain extent original
The shortcomings that radiation-proof fabric is airtight, fabric plate is hard.Different according to the length of fiber, fineness, the dynamics of acupuncture can change,
The number of acupuncture is more, and the cloth formed also can be thinner.
Style influence of the number of acupuncture on fabric is very big, and often, pieces of cloth are thin for acupuncture, and quality is hard, and the fastness of pieces of cloth is high；
Acupuncture number is few, and fabric is abundant, soft texture, and warmth retention property is good, and radiation-proof effect is good.
It should be noted in production process：(1) in laid process, if web is very thin, networking is difficult, during production
Web is pressed with wooden stick, prevents web to be adsorbed onto on deflector roll, influences networking.(2) also need to carry out acupuncture after fiber networking, will
When web introduces needing machine, because the rigidity of web with traction cloth to it not enough, it is necessary to be drawn, otherwise it is difficult to carry out
Acupuncture, and network structure can be destroyed.(3) traction cloth leads web to be passed through among upper and lower spiked roller, in web first
During into upper and lower licker-in, feeding is helped with Handball Association, must now be taken care, prevents from causing personal injury.
3 results of study
The radiation-proof effect of fabric is influenceed, mixing when three factors of acupuncture number for having every Gram Mass, fiber.Face
Material every Gram Mass it is bigger, radiation-proof effect is better, but often Gram Mass it is big, on the one hand can increase fabric into
This, the opposing party's fabric can seem too fat to move, and quality can be hardened, and influence the comfort of fabric and attractive in appearance.Main discuss of the invention mixes
Than with influence of the acupuncture number to radiation-proof effect.
In invention, silver fiber and the mixed proportion of nano silver fibre are studied in two kinds of situation, are silver-colored fine respectively
Dimension/nano silver fibre 65/35 and 50/50, for both mixing ratios, made six pieces of fabrics respectively, fabric it is average every square
Mick weight is 36.8g/m2, cloth specimen 1-3 is 50/50, and cloth specimen 4-6 is 65/35, and cloth specimen 1-3 and cloth specimen 4-6 acupuncture number are
1 time, 2 times and 3 times.Radiation-proof nonwovens piece is respectively overlay on computer screen or mobile phone, measured.
Apparatus measures switch is opened, by instrument head close to emission source, point horizontal, vertical, the direction adjusting device angle of side three,
The larger direction of read off value is monitored.First with electromagnetic detection instrument alignment computer screen and mobile phone, its radiation value is surveyed respectively, so
Computer screen and mobile phone are blocked using radiation-proof fabric afterwards, surveys electromagnetic radiation value now respectively, it should be noted that during reading
Take high frequency numerical value.Measurement is averaged twice, and test result is as shown in table 1.
The electromagnetic shielding value test result (μ t) of the computer of table 1
The data of table 1 are contrasted, for computer screen, electromagnetic radiation value is reduced to 0.41 μ t (cloth by 4.18 μ t
Sample 5)；The electromagnetic radiation value of mobile phone is reduced to 0.43 μ t (cloth specimen 5) by 4.61 μ t, it can thus be seen that this Novel radiation-protection
Clearly, electromagnetic shielding value is minimum to drop to 0.41 μ t to the effect of fabric, the safe radiation value of very close human body, people
The safe radiation value of body is as shown in table 2.
The electromagnetic radiation country grade scale of table 2
Therefore it is the scope that is perfectly safe less than 0.1 μ t, 0.1 μ of μ t -0.4 t are to belong to secondary standard scope, but can be to people
Body brings adverse effect.
Pass through the comparison of silver fiber/nano silver fibre mixing ratio 65/35 and 50/50, it is evident that 65/35 effect is more
Add, so the content of silver fiber is more, shielding property effect is better, therefore can be according to different purposes from different
Mixing ratio.For same mixing ratio, the radiation-proof effect of acupuncture twice is preferable, shadow of the analysis acupuncture number to radiation-proof effect
Ring, when acupuncture number is few, pieces of cloth are thicker, and the gap between fiber is larger, and the radiation-proof effect of pieces of cloth is poor；When acupuncture number
During increase, interfibrous gap diminishes, and can increase the effect of radiation proof, but often increases an acupuncture, can all cause fiber
Fracture, along with the pinprick that acupuncture leaves, the radiation-proof effect for instead resulting in pieces of cloth is deteriorated.In addition, found in test result,
The different places electromagnetic shielding value of one piece of fabric has difference once in a while, analyze its reason be silver fiber distribution not enough uniformly, institute
In experiment afterwards, also more fully to be mixed.
4 fabrics are compound
The front of fabric is made of Pure Cotton Fabric Printing cloth, this calico of pure cotton makees the reverse side of fabric, Radiation-proof nonwovens piece conduct
Sandwich layer is placed on centre, and three shell fabrics are carried out into quilting using DH-3 computer quilters.According to the size of quilter, upper and lower two aspect
The specification of material at least needs 1m × 1m, then selects the grain pattern of quilting on computers, selects simple rhombus grain pattern setting machine,
Upper and lower two shell fabric and centre radiation-proof fabric must fixation, otherwise can make the fabric out-of-flatness after quilting.
Radiation-proof effect preferably non-woven pieces of cloth 3,4,5 are subjected to quilting, the radiation-proof fabric novel appearance after quilting,
The skin color of Pure Cotton Fabric Printing cloth, floral designs are rich and varied, and the nexine of pure cotton cloth can be worn next to the skin, and the presence of quilting line changes
It has been apt to the defects of conventional radiation-proof fabric can not wash.
5 cost accounting and contrast
It is computed learning, 36 yuan every square metre of silver fiber/nano silver fibre 50/50, silver fiber/nano silver fibre 65/35
42 yuan every square metre, quilting fabric and 30 yuan of every square metre of processing charges, 50 yuan of clothes processing charges, the cost of a clothes are most not
More than 150 yuan.By research, the price of in the market exposure suit typically in 200-1000 members, what general pregnant woman wore
Suspender clothes is at 400 yuan or so, and compared with the radiation-proof fabric clothes that we develop, price has larger difference, and the fabric is very
It is adapted to general population to use, for fabric developer, fair margin of profit will be obtained.
6 conclusions
(1) when preparing radiation proof pieces of cloth using nonwovens process, silver fiber and nano silver fibre mixing must be ensured
Uniformly, the radiation-proof effect of fabric otherwise can be caused unbalanced.The non-woven pieces of cloth worked it out using needle point method are soft, non-
Often it is adapted to do wearing fabric and auxiliary material, the number of acupuncture has an impact electromagnetic shielding value, with the increase of acupuncture number, electromagnetic screen
Cover value and first subtract and increase afterwards, so radiation-proof effect is optimal twice for acupuncture.
(2) it is compound to radiation-proof fabric progress using quilting technology, quilting grain pattern, top layer can be selected according to the purposes of fabric
Fabric and nexine fabric, surface layer fabric can arbitrarily select in the existing fabric in market, nexine fabric selection pure cotton cloth, change
Conventional radiation-proof fabric dyeing is difficult, can not wash, be not suitable for the shortcomings that underwear.Improve radiation-proof fabric stylishness,
Washability and comfortableness, this is an important breakthrough of radiation-proof fabric.
(3) using silver fiber as primary raw material, value-added content of product is improved, because silver fiber is not only with extraordinary
Radiation-proof effect, and the function such as also good antibacterial and deodouring, antistatic, it is difficult that radiation-proof fabric, which integrates these performances,
Can be valuable.But the price of silver fiber is relatively expensive, it is relatively inexpensive but have a small amount of radiation proof work(thus to mix part of price
The nano silver fibre of energy, the cost of radiation-proof fabric is reduced with this.Find by cost accounting, made with this radiation-proof fabric
The cost of clothes is no more than 150 yuan, and the price of in the market exposure suit is typically in 200-1000 members, by contrast
Price has larger difference, and the fabric is especially suitable for general population's use, for fabric developer, will obtain considerable profit
Profit.
(4) Radiation-proof nonwovens piece can do maternity dress by quilting, can also be used as the auxiliary material of business suit, can be with
In the different parts of clothes, selective does some radiation-proof effects, as mobile phone is often mounted in coat pocket or trousers by man
Rim of the mouth bag, pocket liner can be done with the non-woven pieces of cloth of the mixing ratio of silver fiber/nanofiber 50/50, can so reduce hand
Machine carrys out electric radiation, and and can is connected to mobile phone signal.Can also be made of Radiation-proof nonwovens piece mobile phone bag, tablet personal computer set in
Lining, or vest and good-looking liner clothes are made, convenient cleaning, reduce radiation.
