Problems solved by technology

However, the hot air crimping is carried out after the fiber web is formed, and the bonding and crimping are completed simultaneously, so that the curling of the fibers is limited due to the surface bonding between the fibers before the composite fibers are crimped, thereby affecting the bulkiness of the spunbond nonwoven fabric. Sex, and the use of air drafting, the fiber size formed is limited, which affects the softness of spunbond nonwovens

Embodiment 1

[0065] Such as Figures 1 to 4C Shown, the present invention also discloses a kind of manufacture method of spun-bonded non-woven fabric, comprises the following steps:

[0066] (1) Low-melting-point resin polyethylene and high-melting-point polypropylene resin with a difference of two melting points ≥ 20°C extrude the high-temperature melt through the hot-melt extrusion device A1 and A1' respectively and enter the spinning device B. In device B, the high-temperature melt is turned into a thin stream of melt, and then sprayed out through the spinneret B1 of the spinning device B, and the side-blown cold wind C1 cools the thin stream of the melt to form a thick two-component spunbonded long fiber a1, And the thick two-component spunbond long fiber a1 is two-component sheath-core type spunbond long fiber d, two-component orange segment type spunbond long fiber e or two-component side-by-side spunbond long fiber f; The surface layer d2 of the core type spunbond long fiber is a l...

Embodiment 2

[0072] Such as Figure 5 Shown, the present invention also discloses a kind of manufacture method of spun-bonded non-woven fabric, comprises the following steps:

[0073] (1) Low-melting-point resin polyethylene and high-melting-point polypropylene resin with a difference of two melting points ≥ 20°C extrude the high-temperature melt through the hot-melt extrusion device A2 and A2' respectively and enter the spinning device B. In the device B, the high-temperature melt is changed into a thin stream of the melt, which is then ejected through the spinneret B2 of the spinning device B, and the side-blown cold wind C2 cools the thin stream of the melt to form a woolen bonded long fiber a2, wherein the The spunbond long fiber a2 includes thick bicomponent spunbond long fiber and thick monocomponent spunbond long fiber whose fiber surface is a low-melting point resin.

[0074] (2) The formed spunbond long fibers a2 enter the mechanical drafting device D2 to mechanically stretch the...

Embodiment 3

[0079] Such as Figure 6 Shown, the present invention also discloses a kind of manufacture method of spun-bonded non-woven fabric, comprises the following steps:

[0080] (1) The difference between the two melting points ≥ 20°C. Polyethylene resin and polyester resin extrude high-temperature melts through hot-melt extrusion devices A3 and A3' respectively and enter spinning device B. In spinning device B, the high-temperature The melt becomes a thin stream of melt, and is then ejected through the spinneret B3 of the spinning device B, and the side-blown cold wind C3 is cooled to form a roving bonded long fiber a3, wherein the roving bonded long fiber a3 contains a fiber surface of Thick two-component spunbond long fibers and thick one-component spunbond long fibers of low-melting resins.

[0081] (2) The formed spunbond long fibers a3 enter the mechanical drafting device D3 to mechanically stretch the spunbond long fibers a3 to form spunbond long fibers, which include two-com...

Abstract

The invention discloses manufacturing equipment of a spunbonded non-woven fabric. The manufacturing equipment comprises hot melt extrusion devices, a spinning device, a side cold air blowing device, amechanical drafting device, a hot air crimping device, a wire and net laying device, a net forming device and a cutting and winding device which are sequentially connected to one another; the hot melt extrusion devices at least consist of two groups and are connected to the spinning device; the mechanical drafting device is provided with at least three drafting rollers, the drafting rollers are longitudinally staggered and arranged on both sides of the lower portion of the side cold air blowing device in two groups and can be horizontally moved to the same vertical line, and the rotation speeds of the drafting rollers close to a spinneret plate are sequentially lower than those of the drafting rollers away from the spinneret plate; the hot air crimping device is located at hot air blowingpositions on both sides of the hot air blowing device just below the mechanical drafting device, and the range of an included angle between a side hot air blowing direction and the longitudinal direction is from 5 degrees to 90 degrees. The invention also discloses a manufacturing method of the spunbonded non-woven fabric. The spunbonded non-woven fabric produced by means of the manufacturing equipment and the manufacturing method is soft and fluffy.

Description

technical field [0001] The invention relates to the technical field of spun-bonded non-woven fabrics, in particular to a soft and fluffy spun-bonded non-woven fabric manufacturing equipment and a manufacturing method for personal care and infant care. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, have been industrialized in the United States since 1942. Due to their simple production process, large output, low cost, and wide range of product applications compared with traditional woven fabrics, they have become a textile The fastest growing emerging field in the industry. Among them, the spunbond nonwoven fabric is usually made of thermoplastic resin through the extruder to form long fibers from the spinneret. After laying the net, the metal hot roller is used for partial hot rolling to bond the nonwoven fabric fibers. Due to its production process, it is formed in one step. It saves cost and is composed of long fibers without raised fibe...
