Description
Technical field
The present invention relates to be combined tarpaulin field, more particularly, to a kind of tarpaulin with filament spunbond nonwoven cloth as base fabric
And its production method.
Background technology
In recent years, the fast development of new material and production technology improves CHINESE INDUSTRIES textile kind and quality,
Shelter cloth has equally also obtained quick development as major class traditional in fabrics for industrial use.But from the use feelings of its base fabric
From the point of view of condition, be still with chemical fibre warp knit, woven fabric coating polyvinyl chloride or polyethylene the fluffy cover material of coating based on, mainly have with
Under several technological processes：
(1) PE tarpaulins
Colour bar cloth is generally referred to, in the two-sided painting PE films of PE woven cloths, its production technology is：PE wire drawings → circular woven cloth → two-sided
Film → cold pressing → wind, is characterized in：Breadth is big (can accomplish 6m now), and light weight has the disadvantage：It is not durable, after once
Drainage may just occurs；
(2) PVC tarpaulins
Woven dacron or terylene cord fabric double plastic-coated PVC paste resin are generally referred to, due to being impregnation, in cloth gap
There is PVC in face, and water resistance is good, and its production technology is：Woven dacron → leaching modeling → drying → press polish → cooling → winding, feature
It is：Good waterproof performance.Have the disadvantage：Not wear-resisting, tensile strength is small；
(3) high-strength canvas tarpaulin
The tarpaulin produced by top finish with high-strength woven cloth is generally referred to, technological process is：Base fabric → hot rolling → mono-
Finishing coat → gel → cooling → winding, is characterized in：Tensile strength is big, wearability is good, has the disadvantage：Flexible inadequate, weight is big.
Under normal circumstances, the use requirement to tarpaulin is：1. intensity is high, wear-resistant；2. lightweight, foldable；3. waterproof,
Mould proof, fire prevention；4. without wicking.
As can be seen here, current tarpaulin can not fully meet use requirement, all in the presence of some defects, therefore, it is necessary to carry
For a kind of tarpaulin, the shortcoming of existing tarpaulin can be overcome, meet the use requirement of tarpaulin.
The content of the invention
It is an object of the invention to provide a kind of tarpaulin, the intensity of existing tarpaulin, flexible poor and weight can be overcome big etc.
Shortcoming, meets the use requirement of tarpaulin.
To achieve these goals, provide a kind of with filament spunbond nonwoven cloth as base fabric according to the first aspect of the invention
Tarpaulin, the paulin includes base cloth layer and functional coating, and the base cloth layer is filament spunbond nonwoven cloth, the filament spunbond nonwoven cloth
By viscosity for the PET of 0.69-0.71 is obtained.
A kind of tarpaulin production method with filament spunbond nonwoven cloth as base fabric, the life are provided according to the second aspect of the invention
Product method comprises the following steps：
Base fabric is processed, and PET sections are sequentially passed through into crystallizing and drying, melt extruded, spinning cooling, sub-wire lapping, acupuncture adds
Gu and the operation of stentering forming is made base fabric；
Functional coating treatment, rolling and molding, finishing functions and knife scraping coating and press polish cooling are sequentially passed through by the base fabric
Operation be made the tarpaulin；
Wherein, the viscosity of the PET sections is 0.69-0.71.
Provide according to the third aspect of the invention we according to the above-mentioned production of the tarpaulin with filament spunbond nonwoven cloth as base fabric
The tarpaulin of method production.
By above-mentioned technical proposal, the invention has the advantages that：
(1) present invention provide tarpaulin with non-woven fabrics as base fabric, flexible, light weight, with existing PE and PVC tarpaulins phase
Than, with intensity it is big, wearability is good, resistance to ag(e)ing much larger than PE work out laminating adhesive tarpaulin the features such as；
(2) compared with traditional tarpaulin is produced, tarpaulin production method of the invention does not have the complicated technique such as wire drawing, warp knit
Process, but be the tarpaulin production method of base fabric using the non-woven fabrics that polymer net-forming process is directly processed, and then simplify life
Production. art, reduces direct production cost；
(3) present invention solves the problems, such as that non-woven fabrics ultimate strength is inadequate, elongation at break is high so that non-woven fabrics can expire
The sufficient requirement as paulin base fabric；
(4) with non-woven fabrics as base fabric, the weight of base fabric unit area is not only reduced, simultaneously as the porous of non-woven fabrics
And three-dimensional structure, the impregnability of coating material is increased, coating material is not only present in the surface of non-woven fabrics, the fibre of non-woven fabrics
Coating material has also been soaked between dimension and fiber, so as to enhance the wearability of fluffy cover material, the service life of tarpaulin has been extended.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
