Depending on the type, the way of printing is different.

The most widely used spun-bonded nonwovens in the market.

1.1.1 application of non-woven fabrics

At present, there are eight types of non-woven fabrics in China.

[4] the first type of water spines are non-woven, which are sprayed on the web with high pressure micro-water jet. The web can be either a layer or a layer.

The purpose of the spunlaced nonwoven cover for surgery, surgery and medical shade cloth, medical dressing materials, wound dressings, medical gauze, aviation cloth, clothing lining cloth, coating fabric, use disposable materials, instruments and meters high cloth, electronics industry senior cloth, towel, cotton pad, wet wipes, masks coated materials.

The upper hand feels fluffy, with high moisture absorption and oil absorption.

The second kind of thermal seal type nonwoven fabric is added to the fiber net with the fibrous powder or powder hot melt adhesive material.

Hot air adhesion products have the characteristics of high penging and permeability, but they are low in strength and easy to deform.

With the development of the market, the hot air adhesive products are widely used for its unique style in the use of disposable products manufacturing, such as baby diapers, adult incontinence pads, the fabrics of women's health supplies and towel, bath towel, disposable tablecloths, etc.;

Thick products are used to make cold clothing, bedding, baby sleeping bags, mattresses, sofa cushions, etc.

High density hot melt adhesive products can be used in the production of filter materials, sound insulation materials, shock absorber materials and so on.

The slurry airflow non-woven fabric is a network of airflow forming the fiber board into a single fiber layer.

Wet non-woven fiber raw material is placed in a water medium opening into single fiber, at the same time make different fiber ingredients, made from fiber suspension slurry, suspension slurry to the network, fiber under wet condition into a network to reinforce into cloth.

Spun-bonded non-woven spun-bonded non-woven fabric is in polymer has been after extrusion, stretching to form a continuous filament, filament laid into the net, fiber network by self bonding, hot glue, chemical bonding or mechanical reinforcement method, make fabric non-woven fabrics.

The process of fusible nonwoven non-woven fabric is: polymer feed - melt extrusion - fiber - fiber cooling - into mesh - reinforced fabric.

Stitch-bonded nonwoven stitch-bonded nonwoven cloth is a kind of dry non-woven fabrics, sewing lawmakers is the use of warp knitted coil structure of layer fabric, yarn, textile materials (such as plastic sheets, plastic thin metal foil, etc.) or their combination for reinforcement, made from non-woven fabric.

The needling nonwoven needlework is one kind of nonwoven fabric, and the needling is used to use the puncture of the needle to strengthen the fabric.

1.1.2 application status and development trend of screen printing

Screen printing ink layer is thick, the covering force is strong, it is not subject to the surface shape and the area of the object, has very good flexibility and wide applicability.

The purpose of this study is to print the printing process and process of screen printing on non-woven printing, and there are other printing methods and advantages of these printing methods.

Screen printing is not limited by the size, material and shape of the substrate. The printing method is flexible and varied. The printing equipment is simple and convenient and quick.

With the continuous application of new technology, new equipment and new materials, practitioners face a wide variety of online printing services.

From small lighters to large outdoor advertising light boxes, screen printing displays many of the visual arts effects and special functions that can not be realized by printing, gravure and printing.

The future trend of screen printing is to develop to pollution-free direction and use water-based ink to dissolve the characteristics of the carrier and use water

The dissolving carrier is characterized by: safe, non-toxic, harmless, non-flammable, non-explosive, non-volatile organic gas production.

This way of printing on textiles, signs, electronic products, porcelain decorated with color paper, glass, large-format advertising, packaging, decoration and building materials industries, such as is widely applied without exception have growth.

1.1.3 research significance and content

Nonwoven fabric is a rapidly developing product in recent years. With the continuous improvement of production process, the field of application is expanding and its demand is increasing.
