Embodiment 1

[0057] Example 1 An ultra-wide splicable non-woven fabric and its preparation method

[0058] A preparation method of an ultra-wide splicable non-woven fabric of the present invention comprises the following steps:

[0059] (1) Raw material preparation:

[0060] The required masterbatch of the ultra-wide splicable non-woven fabric of the present invention includes:

[0061] 120-150 parts of polypropylene, 12-25 parts of methyl methacrylate, 1-5 parts of alkyl succinic anhydride, 2-4 parts of coupling agent, 1-4 parts of isophorone diisocyanate, 3-7 parts of fatty acid chloride, 2-12 parts of color masterbatch, 5-13 parts of vinyl acetate copolymer, 0.1-4 parts of antioxidant, 0.5-1.5 parts of ginger powder, 0-0.5 parts of o-acetyl salicylic acid.

[0062] Specifically, the masterbatch required for the ultra-wide splicable non-woven fabric in this embodiment, in parts by weight, includes:

[0063] 144 parts of polypropylene, 13 parts of methyl methacrylate, 4 parts of alkyl...

Embodiment 2

[0094] Embodiment 2 A kind of ultra-wide splicable non-woven fabric

[0095] According to the preparation process of the non-woven fabric described in Example 1, the super-wide splicable non-woven fabric (taking 15gsm as an example) obtained, the indicators are shown in the table below;

[0096]

[0097] The above-mentioned splicable non-woven fabrics are conventionally spliced ​​with conventional adhesives. The splicing joints have strong toughness and strong adhesion, and the joints are tough, and the spinning mesh is not easy to crack, which effectively solves the problem of easy splicing at the joints. The technical problems of broken and easy to crack can be spliced ​​into ultra-wide non-woven fabrics of more than 100 meters, and the application range can be expanded.

[0098] It can be seen from the above table that (1) a super-wide splicable non-woven fabric of the present invention has a MD strength of 32.55N / 5cm, a CD strength of 12.34N / 5cm, an MD elongation of 56....

Abstract

The invention provides ultra-wide splicing nonwoven fabric. According to the ultra-wide splicing nonwoven fabric, the bending rigidity index is 15.4 cm<-1>, and the strength at the spliced position is28.95 N / 5cm. The ultra-wide splicing nonwoven fabric is prepared from following required master batches in parts by weight: 120-150 parts of polypropylene, 12-25 parts of methyl methacrylate, 1-5 parts of alkyl succinic anhydride, 2-4 parts of a coupling agent, 1-4 parts of isophorone diisocyanate, 3-7 parts of fatty acyl chloride, 2-12 parts of color masterbatch, 5-13 parts of vinyl acetate copolymer, 0.5-1.5 parts of ginger powder, and 0-0.5 part of acetylsalicylic acid. The invention further provides a preparation method of the ultra-wide splicing nonwoven fabric. The preparation method comprises the steps of melted extrusion, drafting and hot-pressing. According to the ultra-wide splicing nonwoven fabric, the strength at the spliced position is large, the connector is firm and tenacious, a spinning net is not prone to cracking, hundreds of meters of the ultra-wide nonwoven fabric can be spliced, and the application range is expanded.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and relates to an ultra-wide splicable non-woven fabric, in particular to an ultra-wide splicable non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. [0003] Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0004] Non-woven fabrics can be spliced, and the splicing range can reach tens o...
