Description

Non-woven fabric with three-resistance function

[ technical field ] A method for producing a semiconductor device

The utility model relates to a field of non-woven fabrics, especially a non-woven fabrics with three anti functions.

[ background of the invention ]

In recent years, the spun-melt non-woven fabric is widely applied to many fields such as medical treatment, sanitation, protection, filtration and the like. In high-barrier occasions, such as a paper diaper bottom film material in the sanitary industry, an operating coat, an operating hole towel in the medical industry, a protective garment in the industrial industry and the like, the barrier property of an SMS spun-melt non-woven fabric material cannot meet the requirement, a coating or a PP/PE film is required to be coated, the process is complex, time and labor are wasted, the cost is high, the three-resistance finishing of the non-woven fabric is realized by carrying out blood resistance, antistatic property and alcohol resistance finishing on the non-woven fabric, so that the fabric achieves the effects of blood resistance, antistatic property and alcohol resistance, and the non-woven fabric with the three-resistance function is formed at one time.

[ Utility model ] content

The utility model aims at solving the problems in the prior art and providing a non-woven fabric with three-resistance function, which adopts the multi-die composite process to produce SMMSS non-woven fabric, the lapping sequence is S-M-M-S-S in turn, and the air permeability of the product is good.

In order to realize the above-mentioned purpose, the utility model provides a non-woven fabrics with three anti functions, this non-woven fabrics are for forming SMMSS non-woven fabrics by the production of multi-die head composite technology, include from last to down in proper order lapping first spunbonded fiber layer, first meltblown fiber layer, second spunbonded fiber layer and third spunbonded fiber layer, SMMSS non-woven fabrics is the composite non-woven fabrics with three anti functions.

Preferably, the first spunbond fiber layer, the first meltblown fiber layer, the second spunbond fiber layer, and the third spunbond fiber layer are made of a fiber web to which a certain amount of positive electrostatic charge is applied.

Preferably, the first meltblown fiber layer and the second meltblown fiber layer are made of polypropylene.

The utility model has the advantages that: the utility model discloses a multi-die combined process production SMMSS non-woven fabrics, the lapping order is S-M-M-S-S in proper order, and the product gas permeability is good to through three anti functional finishing liquid to the non-woven fabrics pad the arrangement, make SMMSS composite non-woven fabrics have three anti functions, and adopt the even silk system of static to exert a certain amount of positive static charges for the fibre after the melt spinning cooling, can reduce and the silk, glue the phenomenon of silk, the fibre net is even after the lapping, guarantee the degree of consistency of product. The SMMSS non-woven fabric with the three-resistance function has good air permeability and anti-blood, anti-static and anti-alcohol effects, can replace the PE base membrane of the traditional diaper and sanitary towel, and solves the problem of air impermeability of the traditional base membrane.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
