Problems solved by technology

[0003] At present, most of the existing spunlace fabrics are spunlace non-woven fabrics with plain weave on both sides or holes on both sides, but the two sides of the existing spunlace fabrics with plain weave on both sides are too smooth, the grip is not strong, and the water absorption capacity is low when used as an absorbent material. Low; while the spunlaced fabric with holes on both sides has the problem of rough surface

preparation example Construction

[0033] like image 3 As shown, the present invention also provides a method for preparing the above-mentioned semi-open spunlace nonwoven fabric, comprising the following steps:

[0034] 1) Feeding, opening and combing the fibers into a web;

[0035] 2) Spunlace pre-stabbing, half-opening first-zone spunlace, half-opening second-zone spunlace;

[0036] 3) Arrangement, drying, coiling, inspection, slitting and packaging.

[0037] Wherein, in step 2), the setting condition of the first zone of the semi-apertured spunlace is 3-5 spunlace heads for spunlace entanglement, and the spunlace pressure is 30-120bar; The fixed condition is that 1-2 spunlace heads are spunlace entangled, and the spunlace pressure is 10-20bar; the forming net in the first area of ​​the semi-open spunlace is a spunlace forming mesh curtain with more than 60 mesh; The forming mesh in the second area of ​​the spunlace is 24-40 mesh spunlace forming mesh curtain; the first area with half holes is mainly to ...

Embodiment 1

[0040] like image 3 As shown, this embodiment provides a method for preparing a semi-open spunlace nonwoven fabric, comprising the following steps:

[0041] Raw material preparation: use 1.5D viscose fiber, the mass percentage is 50%; 1.4D polyester fiber, the mass percentage is 50%, and the product weight is set to 50g / ㎡.

[0042] Feeding, opening, and carding of fibers into a web: feed the raw materials into the open feeder according to the above ratio for opening and mixing, and initially open the fiber agglomerates into fiber bundles. After opening and mixing evenly, it is transported to the carding machine. The carding machine further combs the fiber bundles into single fibers, then passes through the messy rollers, and finally passes through the doffer to form a fiber web and spread it on the conveyor curtain to be transported to the next process.

Abstract

The invention discloses a half-hole spunlace non-woven cloth. The half-hole spunlace non-woven cloth comprises a spunlace cloth area (1), wherein a plurality of half-holes (2) are formed in the spunlace cloth area (1), and the half-holes (2) are arranged in the spunlace cloth area (1) in rows and a distance between any two adjacent rows is equal; moreover, a distance between any two adjacent half-holes (2) in the same row is equal; and a distance between any two adjacent half-holes (2) in the same column is equal. The invention further provides a preparation method of the half-hole spunlace non-woven cloth. According to the half-hole spunlace non-woven cloth, one side is in the shape of continuous and smooth flat grains, and the other side is in the state of a plane with concave holes; andthe flat grain side is capable of providing a smooth and comfortable use side, and the concave hole side is capable of providing high solution absorption performance and composite performance for theproduct.

Description

technical field [0001] The invention relates to the technical field of nonwoven materials, in particular to a semi-open spunlace nonwoven fabric and a preparation method thereof. Background technique [0002] The product structure of the existing spunlace cloth is mainly three types of plain weave, jacquard or open-pore structure. The open-pore structure is generally a mesh of 6-22 mesh (generally refers to the number of holes corresponding to the horizontal length of the spunlace cloth per inch). Mainly used in dry and wet wipes, wiping cloths, medical dressings, medical protective materials, leather base cloth, wall cloth, interlining cloth, health care products, etc. [0003] At present, most of the existing spunlace fabrics are spunlace non-woven fabrics with plain weave on both sides or holes on both sides, but the two sides of the existing spunlace fabrics with plain weave on both sides are too smooth, the grip is not strong, and the water absorption capacity is low wh...
