Description
Technical Field
The invention relates to the technical field of non-woven fabrics, in particular to an ultra-filtration embossed melt-blown non-woven fabric and a preparation method thereof.
Background
Nonwoven fabrics, also known as nonwovens, are composed of oriented or random fibers. It is called a cloth because of its appearance and certain properties. The non-woven fabric has no warp and weft, is very convenient to cut and sew, is light in weight and easy to shape, and is popular with hand fans. Because it is a fabric formed without spinning a woven fabric, it is formed by orienting or randomly arranging textile staple fibers or filaments to form a web structure and then reinforcing them by mechanical, thermal or chemical means.
The non-woven fabric is a non-woven fabric which is formed by directly utilizing high polymer slices, short fibers or filaments to form a net through air flow or machinery, then carrying out spunlace, needling, hot air or hot rolling reinforcement, and finally carrying out after-treatment. A novel fiber product having a soft, air-permeable and planar structure, which is strong, durable, silky and soft without generating lint, is one of reinforcing materials, and has a cotton-like feel, and a nonwoven fabric is easy to form and inexpensive as compared with cotton.
The polypropylene fiber is fused and contracted near flame, is inflammable, burns slowly away from the fire and emits black smoke, the upper end of the flame is yellow, the lower end of the flame is blue, the petroleum smell is emitted, and the burnt ash is hard round and light yellow brown particles which are twisted by hands and are easy to break. The polypropylene fiber varieties include filaments (including non-textured filaments and bulked textured filaments), short fibers, bristles, split fibers, hollow fibers, profiled fibers, various composite fibers, nonwoven fabrics and the like. The main application is to manufacture carpets (including carpet backing cloth and suede), decorative fabrics, furniture cloth, various ropes, strips, fishing nets, oil absorption felts, building reinforcing materials, packaging materials and industrial cloth, such as filter cloth, bag cloth and the like. In addition, the application in the aspect of clothing is gradually wide, the fiber can be blended with various fibers to prepare different types of blended fabrics, and the blended fabrics can be made into shirts, coats, sports coats, socks and the like after knitting processing. The quilt made of polypropylene hollow fiber has light weight, good heat preservation and good elasticity.
However, the melt-blown nonwoven fabrics currently used still have the following problems:
1. the melt-blown non-woven fabric has poor filtering and adsorbing performance and poor filtering effect;
2. because the raw materials are difficult to process at present, the spinnability is poor in the production process of the melt-blown non-woven fabric, slurry drops are easy to occur, the color is not easy to be colored, the coloring performance is poor, and the net is not easy to be laid uniformly;
