（2）, by the non-weaving cloth produced through vapor.
Preferably, the parallel type synthesis composite fibre after to main thorn is carried out in drying step, and the non-weaving cloth produced is put in loose formula baking oven, and carrying out the drying without clamping makes which carry out free shrink, to increase its elastic recovery.
It is a kind of that the non-weaving cloth that method is prepared is prepared as above.
Preferably, it is made up of following material,
PET, with components by weight percent ratio as 1 part -10 parts；
Ptt fiber, with components by weight percent ratio as 1 part -10 parts.
Preferably, it also includes functional fibre, with components by weight percent ratio as 0.1 part -5 parts.
Preferably, the functional fibre includes cotton fiber or terylene.
Non-weaving cloth described above is used for the purposes of any one in medical elastic adhesive tape, medical elastic dressing, clothing adjuvant, adult's child's diaper bouncing plate.
The present invention adopts said method, structure and purposes, this kind of carbon fiber water spunlaced nonwoven to have preferably elasticity and its elastic recovery.
Specific embodiment
The specific embodiment of invention described herein, is only used for explaining the purpose of the present invention, and it is limitation of the present invention that can not be understood as by any way.Under the teachings of the present invention, technical staff is contemplated that any possible deformation based on the present invention, and these are regarded as belonging to the scope of the present invention.
The invention discloses a kind of preparation method of non-weaving cloth, it is characterised in that it comprises the following steps：
PET is mixed to form into parallel type synthesis composite fibre with ptt fiber；
Shredding is carried out to parallel type synthesis composite fibre；
Combing is carried out to the parallel type synthesis composite fibre after shredding, fiber disordered arrangements is caused using roller in carding process；
Lapping is carried out to the parallel type synthesis composite fibre after combing；
Parallel type synthesis composite fibre after lapping is prewetted；
Parallel type synthesis composite fibre after to prewetting carries out main thorn；
Drying is carried out to the parallel type synthesis composite fibre after main thorn.
Specifically, it is raw material from pet and ptt composite fibres, which is processed using the production method of hydro-entangled non-woven fabric.Spun lacing production processing process be：The technological processes such as thick shredding → essence shredding → combing → lapping → prewet → prewet → pre- spun lacing → main thorn → drying.As fiber has the crimpiness of height in carding process, therefore for shredding carding process causes very big impact, therefore in process generally using card clothing is changed, it is uniform to reach lapping to improve carding process.Carding process is referred to, bulk fibers are carded to into single fiber, some mechanisms can be added on carding machine and improve carding effect, such as double doffer mechanisms can cause dual-layer web to overlap uniformly on carding machine；Increase mixed and disorderly roller on carding machine and can cause fiber disordered arrangements, to reduce product vertically and horizontally difference.The pin of carding machine is furnished with different types, can be according to the difference for being processed raw material come from different pin cloth, when carding machine carded fiber, and fiber can not be into will more needle exchange cloth during single or pencil.Fiber to be caused as far as possible to be carded in the combing stage single, so that lapping is more uniform.
Preferably, PET is mixed to form parallel type synthesis composite fibre with ptt fiber in step also includes for functional fibre and PET, ptt fiber being mixed to form parallel type synthesis composite fibre.For pet can be mixed with other fibers with ptt composite fibres so as to reach different performances, for example, can carry out mixing the hydrophilic for making which with cotton fiber and be improved；Blending is carried out with terylene and can improve stiffness of non-weaving cloth etc..Pet and ptt composite fibres are the production for being applied to hydro-entangled non-woven fabric first, in order to improve its carding effect, give elastic cotton hydro-entangled non-woven fabric more functions, can be mixed with other fibers, according to the different purposes that product is final, the adding proportion of composite fibre is from 60%-90%.
Preferably, the parallel type synthesis composite fibre after to prewetting carries out main thorn and the synthesis composite fibre of the parallel type after to main thorn carries out also including arranging step between drying step, and the arrangement step includes：
（1）, the non-weaving cloth produced boiled into cloth through hot water, the temperature of hot water is about at 30-100 DEG C；So that ptt fiber is dissolved so as to reach so that its elastic recovery is improved.
（2）, by the non-weaving cloth produced through vapor, using vapor steam cloth by non-weaving cloth by vapor so that fibrolysises so that recovery increases.
Preferably, the parallel type synthesis composite fibre after to main thorn is carried out in drying step, and the non-weaving cloth produced is put in loose formula baking oven, and carrying out the drying without clamping makes which carry out free shrink, to increase its elastic recovery.When which carries out drying on drying rolls, act in longitudinal under tension, so that its elastic recovery declines, when being put into loose formula baking oven and carrying out drying, two ends do not stress without clamping, so that elastic force cotton fiber being capable of abundant free shrink.
The invention discloses a kind of non-weaving cloth, which adopts said method to make.
