The non -weaving cloth has that high elasticity, tensile return uniformity, thickness are adjustable, gas permeability and soft performance of feeling, has antibioticly, antistatic and the environmental protection is nontoxic again.
Description
Technical field
The utility model belongs to health care and medical instruments field, and for the manufacture of paper diaper for infant, adult incontinence pants, liner, facial mask etc., particularly, relate to a kind of non-weaving cloth, particularly relates to a kind of medical elastic non-weaving cloth.
Background technology
Non-weaving cloth, also known as non-woven material, nonwoven fabric, supatex fabric, adhesive-bonded fabric or non-woven fabrics, a kind ofly do not need to spin cotton and weave cloth and the fabric formed, just textile staple or long filament are carried out orientation or random alignment, form fibre net structure, then adopt machinery, the method such as hot sticky or chemical reinforces and form.The tencel goods with softness, ventilative and planar structure that it directly utilizes that high polymer is cut into slices, short fiber or long filament are formed by various web forming method and concretion technology.
Due to non-weaving cloth, to have technological process short, speed of production is fast, output is high, cost is low, purposes is wide, the features such as raw material sources are many, it is made extensively to welcome by manufacturer, at present, in health-care medical field, such as paper diaper for infant, adult incontinence pants, liner, facial mask, operating coat, protective garment, sterilization infantees, mouth mask, diaper, the products such as sanltary towel, its fabric adopted is mostly non-woven material (i.e. non-woven fabrics), such as spun-bonded non-woven fabrics, needle punched non-woven fabrics, heat seal non-woven fabrics etc., this kind of non-woven material contacts with body skin, due to poor air permeability, often can cause hot prickly heat, skin such as to be itched at the skin symptom, and due to long-time and skin contact, frequent meeting is because of friction generation electrostatic problem.
To this, Chinese patent 201120078350.1, discloses a kind of manufacture field of non-woven fabrics, provides that a kind of air permeable effect is good, antibacterial, waterproof, and Medical non-woven fabric comfortable and easy to wear, the melt spraying non-woven fabrics comprising upper strata spun-bonded non-woven fabrics, lower floor's antibacterial nonwoven cloth and be located between the two.This Novel medical non-weaving cloth is mainly used in making the disposable products such as medical surgical gown, protective garment, barrier gown.But this patent only volume uses traditional spun-bonded non-woven fabrics, antibacterial nonwoven cloth and melt spraying non-woven fabrics between the two, but does not specifically provide the material of non-woven fabrics, and existing traditional non-woven cloth is controversial in wearing comfort.
Utility model content
For solving above-mentioned Problems existing, the purpose of this utility model is to provide a kind of medical elastic non-weaving cloth, described non-weaving cloth has that high resiliency, stretching return uniformity, thickness are adjustable, the performance of gas permeability and soft feel, has again antibacterial, antistatic and environment-protecting asepsis.
For achieving the above object, the technical solution of the utility model is:
A kind of medical elastic non-weaving cloth, comprising: the first hypothallus of stacked setting from the bottom to top, antistatic layer, antibiotic layer and the second hypothallus; The composite fibre that described first hypothallus and the second hypothallus are formed by polypropylene and thermoplastic polyester elastomer melting, spray silk is respectively staggered to be formed; Described antistatic layer is polyaniline nano fiber layer.
Further, be also provided with fortifying fibre layer between described first hypothallus and antistatic layer, described fortifying fibre layer is the one in artificial silk layer, carbon fiber layer or flax fiber layer.
Separately, described antibiotic layer is the nonwoven layer being coated with Ag-carried nanometer titanium dioxide.
Separately have, described composite fibre cross sectional shape is cross.
Again, in described composite fibre, the weight ratio of polypropylene and thermoplastic polyester elastomer is 1 ~ 3:1.
