MEthod for fabricating covering material of non-woven fabrics and product

Abstract

The present invention relates to a production method of nonwoven fabric film-covered material and its finished product. Said production method includes the following steps: making a fibre undergo the processes of opening, scutching and carding treatments to obtain a fibre fleece layer, consolidating said fibre fleece layer, spray-coating one side of said fibre fleece layer with a layer of molten high-molecular film and printing figure or pattern on another side of said fibre fleece layer so as to form the invented nonwoven fabric film-covered material finished product. Said invention also provides its application range and finished products made up by using said nonwoven fabric film-covered material.

Description

technical field [0001] The invention relates to a method for manufacturing a non-woven fabric coating material and its finished product, in particular to a non-woven fabric coating material finished product with consistent and simple manufacturing process that can be used as the bottom layer of a diaper or as a personal hygiene product. Such as the manufacturing method of non-woven fabric covering materials for packaging materials of diapers, sanitary napkins or panty liners, waterproof materials or waterproof and breathable materials. Background technique [0002] In the existing manufacturing method of non-woven fabric sticking film, the manufacturer first buys back the non-woven fabric and the film respectively, then sticks the film on one side of the non-woven fabric, and prints patterns or patterns on the other side, and the finished product can be used as a The bottom layer of paper diapers, and when it is used to package a single piece of sanitary napkin, a release pa...

Problems solved by technology

[0002] In the existing manufacturing method of non-woven fabric sticking film, the manufacturer first buys back the non-woven fabric and the film respectively, then sticks the film on one side of the non-woven fabric, and prints patterns or patterns on the other side, and the finished product can be used as a The bottom layer of paper diapers, and when it is used to package a single piece of sanitary napkin, a release paper is first pasted on the back glue of the single piece of sanitary napkin, and then the finished product is used for wrapping packaging, and the pattern or pattern Exposed, increase its attractive in appearance, the shortcoming of the manufacturing method of this existing non-woven fabric covering material is:

[0003] 1. It is necessary to buy back non-woven fabrics and films separately, which increases inventory and material costs

[0004] 2. To stick the film on one side of the non-woven fabric, it is necessary to purchase a machine, which increases the cost, and the length of the non-woven fabric is limited, although the length of the non-woven fabric is limited. When a batch is processed, it needs to be shut down and replaced with a new batch of non-woven fabric. , incoherent, low productivity

[0005] 3. If you want to pack a single piece of sanitary napkin, you need to purchase another release paper and use a machine to stick it to the back glue of the single piece of sanitary napkin, which also increases the cost of materials and machines

[0006] 4. Whether it can be used as the bottom layer of diapers or used to pack a single piece of sanitary napkin, the manufacturing process is divided into multiple procedures and incoherent, time-consuming and uneconomical
