The concept of hydroentangled nonwovens:Hydroentangled nonwovens,also called hydroentangled nonwovens,are also known as"jet sprayed fabrics".The concept of"jet spraying"comes from the mechanical needling process.The so-called"jet spraying"is the use of high-pressure water jet into the fiber network,so that the fibers entwine with each other,so that the original spunlace nonwoven to loose fiber network with a certain strength and complete structure.
The process of spunlace nonwoven fabric is:fiber metering and mixing-opening and debinding-mechanical mess combing into a network-fiber network pre-wetting-water needle cross-winding-surface treatment-drying-winding-inspection-packaging into storage.Jet spraying device is the use of high speed flow of high pressure water jet spunlace manufacturers,so that the fibers in the fiber network rearrangement,mutual entanglement,into a complete structure,with a certain strength and other properties of the nonwoven fabric.
The physical properties of this spunlace nonwoven are different from those of common needled nonwovens,and it is the only nonwoven that can make its final product resemble a textile,both in terms of handfeel and microfiber nonwoven performance.Superiority of the hydroentanglement method.
There is no extrusion of the fiber web in the hydroentanglement process,thus increasing the bulkiness of the final product;no resin or adhesive is used,thus maintaining the inherent softness of the fiber web;the high degree of integrity of the product avoids fluffiness;the fiber web has high mechanical strength,up to 80%to 90%of the strength of the textile;
the fiber web can be mixed with any variety of fibers.Especially worth mentioning is that the spunlace can be compounded with any base fabric to make composite products.Various functions can be produced according to different applications.
Advantages of spunlace nonwoven fabrics:1,soft,good drapability;2,good strength;3,high moisture absorption and quick moisture;4,low pilling;5,washing resistance;6,no chemical additives;7,appearance similar to textiles.
Prospects of spunlace nonwoven:Due to the advantages of spunlace,it has become one of the fastest progressing areas of technology in the non-manufacturing world in recent years.
The development direction of spunlace is to replace textile and knitted products,spunlace with its most textile-like characteristics,excellent physical properties,the advantages of good value for money to become the most promising areas of competition with the textile market.
Application of spunlace.First,the medical aspect with namely abandoned surgical gown,surgical cover cloth,operating table cloth,surgical apron,etc.;wound dressing material,bandage,gauze,band-aid,etc.;
Second,clothing such as clothing interlining,baby clothes,training clothes,carnival night disposable colored clothing,various types of protective clothing such as surgical gowns,etc.;
Third,wipes such as household,personal,beauty,industrial,medical dry and wet wipes,etc.;
Four,decorative cloth such as car interiors,home interiors,stage decoration,etc.;
V.Agricultural fabrics such as heat preservation greenhouse,weed growth prevention,harvest cloth,insect preservation cloth,etc;
Sixth,spunlace can also be used for composite processing,can produce"sandwich"type structure of the product,the development of a variety of new composite materials.Spunbond Nonwoven Spunbond Nonwoven:After the polymer is extruded and stretched to form continuous filaments,the filaments are laid into a web,and the web is then bonded,thermally bonded,chemically bonded or mechanically reinforced to make the web into a nonwoven fabric.
Features:high strength,good high temperature resistance(can be used in 150℃environment for a long time),aging resistance,UV resistance,high elongation,good stability and breathability,corrosion resistance,sound insulation,mothproof and non-toxic.
Main uses:spunbond nonwoven fabrics are mainly polypropylene polyester(long fiber,staple fiber)we are most common and most commonly used is the application of nonwoven bags,nonwoven packaging,etc.,and it is also easy to identify,because the rolling point of spunbond nonwoven fabrics is diamond-shaped.
