Abstract
The invention discloses a kind of cloth seam constructions and the preparation method and application thereof.The cloth seam construction includes at least two cloth products layers, the cloth products layer includes thermoplastic resin fibre's product layer, or, the cloth products layer includes thermoplastic resin fibre's product layer and the liquid barrier material layer for being set to thermoplastic resin fibre's product layer surface, the seam crossing of two cloth products layers is provided with Resin adhesive layer at least in, it is sealingly engaged two cloth products layers, the Resin adhesive layer is formed by curing by the response type adhesive that can be set to the cloth products layer surface and/or inside.Cloth seam construction of the invention and corresponding clothing such as medical operating clothes, medical protection clothes etc. have the function of high stable liquid barrier property and anti-virus, while having performances, the application prospects such as durable and high-tenacity extensive.
Description
Technical field
The present invention relates to a kind of cloth seam construction product, more particularly to it is a kind of based on textile, non-woven fabrics and its spread out
Raw joint product medical operating clothes, industrial protection clothes etc. seam converted products.
Background technique
Textile, non-woven fabrics and a variety of composite materials derived from it have been widely used in various clothing finished products at present, such as
Ordinary clothing, medical operating clothing, medical protection clothes, industrial protection clothes etc..In ready-made clothes machining process, cloth, which needs, to be connect
Seam.Such as coat-sleeve, shoulder, neckline.Common joint technique has sewing, ultrasonic compressing, thermal-adhering etc..
In application aspects such as medical operating clothes, barrier gown, medical protection clothes, industrial protection clothes, it is necessary to have very high resistances
It every property, prevents in its application environment, such as hospital operating room, epidemic-stricken area, chemical plant, disaster field application places, hazardous substance
Such as body fluid, blood, bacterial virus, soda acid liquid, toxic organic compound pass through clothes and damage human body.
To meet the above demand, have above in the designing and manufacturing of the clothes of physical protection function, on the one hand, logical
It crosses and uses the Strand Feeding Techniques such as feltwork weaving and non-woven fabrics and the progress of cloth and film compound, there are clothing materials and hinder
Every property.On the other hand, it at the positions such as the seam of cloth, connector, such as coat-sleeve seam, shoulder seam, cuff, needs by effective
Method guarantees the sealing of seam crossing, so that finished garment be made to have fine protective performance.Meanwhile medical operating clothes are needed by ring
Oxidative ethane or steam sterilizing processing, seam crossing need to keep after these sterilising conditions stable sealing effect.
However, sewing, ultrasonic compressing and thermal-adhering these traditional seaming methods have respective defect.Use linear slit
The method threaded is actually and not formed strict seam.Gap and needle-penetration line between cloth is practical to the destruction of cloth
On make seam crossing that can not form strict barriering effect to the various liquid that endanger.Typical such as industrial protection takes, and passes through sewer
After skill carries out coat-sleeve seam, generally require seam crossing again adhesive tape to reach sealing effect.Ultrasound involves heat sealing technology
Principle is to make two panels cloth be softened or melted to form one in seam crossing local heating cloth by ultrasound or hot pressing item, it
Cooling forms seam construction product after restoring solid state afterwards.By taking polypropylene non-woven fabric as an example, temperature reaches 130 degrees Celsius or more
When, polypropylene starts to soften and gradually melt, thus the fusible melt for forming one of two panels cloth seam crossing.
Ultrasonic wave and hot pressing both methods theoretically can form continuous closely sealed seam in seam crossing, to be formed
Good barriering effect achievees the purpose that protection endangers liquid.However, both methods is in large-scale production to process conditions
Setting and stability in terms of have very big challenge.
Ultrasonic method has higher requirements to pressure, ultrasonic roller surface cleannes etc..Such as in continuous production, melting
Cloth has a few fibres and is bonded in roller surface, with bond amount increase and roller surface uneven distribution, meeting
The product seam of subsequent production is set physical defect occur.
The method of hot pressing, three-layer structure material is such as previously mentioned in United States Patent (USP) US7390376, and (non-woven fabrics/barrier is thin
Film/non-woven fabrics) seam, method is that it is molten to be heated to internal layer nonwoven layer to the seam crossing of two panels material laminate using fire-bar
Or more, but in barrier film fusing point hereinafter, melting internal layer non-woven fabrics, so that the internal layer non-woven fabrics of two sheet materials melts patch
It is combined the seam for being formed with barrier property.The method is the currently the only widely commercialized medical anti-virus operation dress (U.S.
4 rank of AAMI) product coat-sleeve seam method.However, the method has considerable challenge.First, it needs from outer in principle
Layer nonwoven heating makes heat pass through outer layer non-woven fabrics, middle layer barrier film, finally again by internal layer non-woven fabrics by heat transfer
Material molten.To which the temperature of outer layer non-woven fabrics is much higher than its melting temperature, outer layer non-woven fabrics is set to be also at molten condition, to it
Physical property has larger impact.Second, the stability of hot press and its accessory in large-scale production.Hot press configuration needs
Two hot pressing items above and below about one meter long have very high-precision and are substantially parallel, to keep in hot pressing to cloth
Complete consistent pressure.And size, the stability of shape are kept in the circulation that long-time hot pressing, heating cool down.In temperature control
System aspect, needs to keep the temperature uniformity of whole hot pressing item and the accuracy of set temperature.Simultaneously as need heat from
Outer layer is conducted to internal layer, and internal layer is made to reach the temperature of melting, and influence, quality fluctuation of material of external condition etc. will affect work
The stabilization of skill window.Third, in large-scale production, if more than a small amount of melting macromolecule sticks on fire-bar and can significantly destroy
Needs various accurate equipment and process conditions.These problems make hot pressing method equally in commercialization seam barrier property side
There is very big challenge in face.
On the other hand, the melt processing to high molecular material is belonged to thermal-adhering scheme due to ultrasound, and operated
All in air, there is oxidative phenomena inevitably to destroy the initial performance of high molecular material, while melting cools down again
Processing, melt crystallinity of the high molecular material of seam region etc. and also have change compared with cloth.So that is shown is
Cloth is compared by the seam strength that this two methods is processed to be decreased significantly.Such as initial cloth is poly- the third of 50 grams/m
Alkene spins molten (SMS) nonwoven cloth material, and initial strength is 50N/5cm (cloth tearing), after heat sealing, strongly drops significantly to
10-15N/5cm, and tearing occurs in primarily in the edge of seam and cloth.The decline of seam crossing strength causes in use process
In, since the movements such as toggle cause coat-sleeve seam crossing to will appear phenomenon of cracking, thus make the disabler of operation dress and protective garment,
Infection, pollution etc. is brought to cause the injury to human body.
Seamed product based on adhesive technology is also described in United States Patent (USP) US 4,114,200.The invention uses heat
Melten gel cooperates sewing technology to reach sealing effect and need joint strength.But it does not embody effectively to nuisance wherein
The barrier action of matter.Meanwhile there is balance various aspects of performance requirement in common hot melt adhesive, water-base cement etc., include ensuring that uniform sizing,
Ensure effective infiltration of the glue to adhesive surface cloth, it is ensured that form fine and close barrier, final joint strength and subsequent processing are as sterilized
The problem of condition stability inferior.Such as rubber-based hot melt glue in order to be maintained under the conditions of steam sterilizing and can soften, flowing leads to seam
Form defect.
In the Chinese patent of Publication No. CN1774332A, thermoplastic seam seal tape, the i.e. hot melt of tape backing are used
Adhesive phase cooperates the fluffy textile fabric of bi-component to help to achieve the effect that seam crossing waterproof.Its bi-component used first
Fabric needs a kind of component to keep stablizing under at least 140 degrees Celsius, is selected as 6,6 material of nylon.Medical treatment and industrial protection clothes
Used polypropylene spun-bonded melt-blown nonwoven cloth material has had begun softening under 140 degrees Celsius.Secondly, being added by hot pressing
Work melts thermoplastic seam seal tape and infiltrates through fluffy textile material, so that the closely sealed processing method of seam crossing is formed, with
Above-mentioned listed directly hot pressing mode has similar technique stability challenges.Such as temperature of deviation setting in large-scale production, pressure,
Then thermoplastic seam seal tape can not be melted by ideal design and be penetrated into the woven face bed of material, so that sealing layer is possible to lack
It falls into.The melting temperature of third, the thermoplastic sealing tape used can be lower than 120 degrees Celsius, use steam sterilizing in medical industry
Under the conditions of, softening will cause the defect of seam crossing, to lose protective performance.
