Embodiment 1

[0032] like figure 1 As shown, a system for preparing superhydrophilic nonwoven fabrics includes a cotton feeder 1, an opener 2, a carding machine 3, a mesh belt 4, a hot blast stove 5, a winding device 6 and a cutting machine connected in sequence. Device 8 is provided with a corona device 7 for increasing hydrophilic groups on the surface of the nonwoven fiber between the hot blast stove 5 and the winding device 6, and the corona device 7 is arranged below the nonwoven mesh surface, and the width is the same as The effective width of mesh belt 4 is the same.

[0033] Using PP / PE 2D two-component skin-core structural fibers as raw materials to prepare super-hydrophilic nonwovens includes the following steps:

[0034] S1, opening: the fiber is opened by the opening machine 2;

[0035] S2, carding: after the fibers after opening are carded by the carding machine 3, the mesh is laid on the mesh belt 4;

[0036] S3, hot air setting: thermally bonding the fiber web after laying...

Embodiment 2

[0042] Using PET / PE 1.5D two-component skin-core structural fibers as raw materials to prepare super-hydrophilic nonwovens, including the following steps:

[0043] S1, opening: the fiber is opened by the opening machine 2;

[0044] S2, carding: after the fibers after opening are carded by the carding machine 3, the mesh is laid on the mesh belt 4;

[0045] S3, hot air setting: thermally bonding the fiber web after laying through the hot air furnace 5, so that the nonwoven fabric is shaped;

[0046] S4, corona treatment: Corona treatment is carried out on the nonwoven fabric after shaping through the corona device 7, so that the surface of the fiber generates hydrophilic groups, and the watt density parameter of the corona device 7 is set to 20w / m 2 / min;

[0047] S5, winding: the nonwoven fabric treated by the corona device 7 is wound into a roll by the winding device 6;

[0048]S6. Slitting and packaging: the roll-shaped nonwoven fabric is slit and packaged by the slitting...

Abstract

The invention discloses a system for preparing super-hydrophilic non-woven fabric. The system comprises a cotton feeding machine (1), an opening machine (2), a carding machine (3), a mesh belt (4), ahot-blast stove (5) and a winding device (6) which are sequentially connected with one another, and a corona device (7) for adding hydrophilic groups to the fiber surface of the non-woven fabric is arranged between the hot-blast stove (5) and the winding device (6). According to the system for preparing the super-hydrophilic non-woven fabric, corona treatment is conducted on fiber webs through thecorona device (7), the wetting performance of the surfaces of the fiber webs can be changed, and the non-woven fabric has better hydrophilicity.

Description

technical field [0001] The invention relates to a preparation system for nonwoven fabrics, in particular to a preparation system for superhydrophilic nonwoven fabrics. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or randomly arranged textile short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. It directly uses polymer chips, short fibers or filaments to form new fiber products with soft, breathable and planar structure through various web forming methods and consolidation technologies. [0003] Hot rolling bonding and hot air bonding are two main processing methods in nonwovens thermal bonding reinforcement. Hot rolling bonding refers to a thermal bonding method in which a pair of hot rollers are used to heat the fiber web and a certain pressure is applied at the same time; hot air bonding refers to the use of hot air to p...
