Spinning into a web here mainly refers to the spunbonding method, and its combination with the spunlace method is not a combination of different web forming techniques as described above, but a combination of web forming and consolidation processes. In the past, spunbonding was mainly carried out by thermal bonding (such as hot rolling) and needle-punching to form a thin hot-rolled spunbond product or a thick needle-punched spunbond product. With the continuous development of non-woven fabric technologies such as spunbond and spunlace, the hydroentanglement consolidation technology has been successfully applied to the production of spunbonded nonwoven fabrics in recent years.
The process is that after the spunbonded filament is drawn, divided and laid by the air, the web is transported to the spunlace area, and the multi-channel puncture of the filament web by the high-pressure water jet is performed, and then dried, The filaments in the web are intertwined to form a nonwoven fabric. Due to the special function of the spunlace, the spunbonded nonwoven fabric thus formed has the appearance style and characteristics of the nonwoven fabric which is similar to the spunlace consolidation of the staple fiber, that is, the hand feel is soft, the drape is good, and the ratio is good. Spunbonded fabrics with acupuncture consolidation have higher strength and are closer to the appearance and performance of conventional textiles.
A potential advantage of using a spunlace to entangle a spunbond web is that it can be well compounded with other materials such as carded web or wood pulp web to develop soft, breathable, moisture absorbing properties. Spunbond composite product; it can successfully split split bicomponent spunbond fibers to produce ultrafine fiber spunbond fabric with excellent coverage and softness, thus imparting spunbonded nonwoven fabric technology and Quality is improved to a higher level.
The current advancement of technology enables the spunbonding and hydroentangling processes to be well integrated, with production speeds of up to 500-600 m/min, widths of 5 to 5.5 m, and weight ranges of 10 to 600 g/m2. And because of its high speed and high output, the production of cloth is greatly reduced.
Spunbonded-spun entangled spunbond fabrics can be widely used in surgical gowns, surgical drapes, sheets, wound bandages, gauze, wipes, baby wipes, household and industrial wipes, garment linings, synthetic leather, Various applications such as coated base fabrics, linoleum base fabrics and insulating materials for automobiles.
