The Properties of non-woven fabrics are different

1. Geotextile properties

Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers by needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is cloth-like, with a general width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven filament of non-woven fabrics is well.


2. Properties of non-woven fabrics

Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. They are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, and affordable. Inexpensive and recyclable. For example, polypropylene (pp material) pellets are used as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot pressing and coiling. It is called cloth because of its appearance and certain properties. the Process of non-woven fabrics is progressing rapidly.

Different uses

1. Use of geotextiles

Geotextiles are widely used in geotechnical engineerings such as water conservancy, electric power, mines, highways, and railways. They can be used as filter materials for soil layer separation, drainage materials for mineral processing in reservoirs and mines, drainage materials for high-rise building foundations, and anti-scour for river dams and slope protection. Materials, reinforcement materials for railways, highways, and airport runways, reinforcement materials for road construction in swampy areas, insulation materials for frost and frost protection, and crack-resistant materials for asphalt pavements. Used as reinforcement in retaining wall backfill, or used to anchor retaining wall panels. Construction of wrapped retaining walls or abutments. Reinforce flexible pavements, repair cracks on roads, and prevent road reflection cracks. Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage of soil at low temperatures. The isolation layer between the road ballast and the roadbed, or the isolation layer between the roadbed and the soft foundation. The isolation layer between artificial fill, rockfill or material field and foundation, isolation between different permafrost layers. Anti-filtration and reinforcement. the properties of non-woven fabrics are very good.

2. The use of non-woven fabrics

(1)Easily decomposed non-woven fabric fabrics for medical and sanitary use: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, wet face towels, magic towels, soft towel rolls, beauty supplies, sanitary napkins, sanitary napkins Pads, and disposable sanitary cloths, etc.

(2)Easily decomposed non-woven fabric fabrics for home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc. the process of easily decomposing non-woven fabric fabrics conforms to current standards.

(3) Non-woven fabrics for clothing: lining, adhesive lining, flakes, shaped cotton, various synthetic leather base fabrics, etc.

(4) Non-woven fabrics for industrial use; base materials, reinforcing materials, polishing materials, filter materials, insulating materials, cement packaging bags, geotextiles, covering cloths, etc. for roofing waterproofing membranes and asphalt shingles.

(5) Agricultural non-woven fabrics: crop protection fabrics, seedling raising fabrics, irrigation fabrics, thermal insulation curtains, etc.CSJ Process of non-woven fabrics is very advanced.

(6) Other non-woven fabrics: space cotton, thermal insulation and sound insulation materials, linoleum, cigarette filters, tea bags, shoe materials, etc.

 Process of non-woven fabrics

Different production processes

1. Geotextile production process

The short-filament geotextile is made of short-fiber polyester or polypropylene as the raw material, which is opened by an opener, opened by an opener, and then entered into a storage box. The three-needle needling process of barb and main needling is followed by stretching and trimming; while the filament geotextile is made of brand-new polyester chip pellets, which are melted and plasticized at high temperature, punched into a mesh, and then pre-punched and compounded. Two needle punching processes are performed, and then the edges are trimmed and stretched.

2. Non-woven production process

Non-woven fabrics are not interlaced and knitted together by yarns one by one, but the fibers are directly bonded together by physical or chemical methods. It has no warp and weft threads, so it is very convenient to cut and sew. Easy to style. There are three main production processes:

(1) Spunbond method: Using the principle of melt spinning, the raw materials are melted and kneaded and extruded from a spinneret to form a melt stream, and high-speed quenching air is used to cool the stream, while the fibers are stretched to form The continuous filament is formed into a uniformly distributed monofilament structure through the filament separation process, and is laid on the screen curtain to form a fiber web.

(2) Melt-blown method: The melt extruded by the screw is blown with high-speed and high-temperature air flow, so that the melt stream is stretched at a higher rate to form ultra-fine short fibers, and then stacked on the condensing screen or the web-forming drum Then, a continuous short fiber web is formed, and then a non-woven fabric is made by self-adhesion or other reinforcement processes.

(3) Composite method: A meltblown nonwoven fabric forming machine is added between two spunbond nonwoven fabric forming machines to form a composite production line for producing spunbond fiber webs and meltblown fiber webs stacked on each other layer of non-woven fabric.

Regarding geotextiles and non-woven fabrics, the above are the differences and differences that CHENSHUJI has sorted out for you. I hope it can be helpful to you. In fact, the connection between non-woven and geotextile is mainly on the product of non-woven geotextile. It mainly refers to a kind of geotextile that does not need to be woven in the manufacturing process, which is consistent with the main characteristics of non-woven fabrics. someone will get it wrong. Decomposable non-woven fabrics are popular.
