Question 5: What is a nonwoven fabric The exact name of the nonwoven fabric should be nonwoven fabric, or nonwoven fabric. Because it is a kind of fabric formed without spinning and weaving, just the textile staple fibers or filaments for directional or random arrangement, the formation of fiber network structure, and then use mechanical, thermal bonding or chemical methods of reinforcement and become. Nonwoven fabric breaks through the traditional textile principles, and has a short process, fast production speed, high yield, low cost, wide range of uses, raw material sources and so on.
Advantages and disadvantages of nonwoven fabrics:
Nonwoven fabrics have a lot of advantages: 1) aeration 2) filtration 3) heat preservation 4) water absorption 5) waterproof 6) stretch 7) not fluffy 8) feel good, soft 9) light 10) elasticity, restorable 11) no direction of the fabric 12) compared with textile fabrics, high productivity, fast production speed 13) low price, can be mass produced! And so on.
The disadvantages are: 1) It has less strength and durability than textile fabric, 2) It cannot be washed like other fabrics, and 3) The fibers are arranged in a certain direction, so it is easy to split at right angles, etc. Therefore, the recent improvements in the production method have been focused on the following. Therefore, recent improvements in production methods have been focused on improving the prevention of splitting.
Its main uses can be roughly divided into:
(1) medical, health nonwoven: surgical gowns, protective clothing, disinfection cloths, masks, diapers, civilian wipes, wiping cloths, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads, and disposable sanitary cloths, etc.;
(2) non-woven fabrics used for home decoration: carpets, wallpaper, tablecloths, bed sheets, bedspreads, etc.;
(2) nonwoven fabrics used for home decor: carpet, wallpaper, tablecloths, bed sheets, bedspreads, curtains, cleaning cloths, mops, etc.;
(3) apparel nonwoven fabrics: lining, bonded lining, wadding, shaping cotton, all kinds of synthetic leather base fabrics, etc.
(4) industrial nonwoven fabrics; automobile headliner, filtration materials, insulating materials, cement bags, geotextile fabrics, covering fabrics, etc.;
(5) agricultural nonwoven fabrics: crop protection fabrics
(6) military nonwoven fabrics: high-performance fiber bulletproof vests, wiping cloth, military map-based cloth, etc.
(7) other nonwoven fabrics: space cotton, thermal insulation materials, absorbent felt, cigarette filters, bags of tea bags, flags, etc.
Classification of nonwoven fabrics
I. Spunlace Nonwoven Fabrics
Spunlace process is a high-pressure micro-flow jetting of water. High-pressure micro-fine water jet to one or more layers of fibers, so that the fibers are intertwined together, so that the fiber network can be reinforced with a certain strength.
Second, thermally bonded nonwoven
Thermally bonded nonwoven refers to the fiber network to add fiber or powder hot melt bonding reinforcing material, the fiber network and then heated and melted and cooled to reinforce the cloth.
Third, the pulp airflow into the net nonwoven
Airflow into the net nonwoven can also be called as dust-free paper, dry paper nonwoven. It is the use of airflow into the network technology will be wood pulp fiber board open into a single fiber state, and then use the airflow method to make the fiber coagulation in the net curtain, the fiber network and then reinforced into the cloth.
Fourth, wet nonwoven
Wet nonwoven is placed in the aqueous medium of the fiber raw materials open into a single fiber, at the same time to make different fiber raw materials are mixed, made of fiber suspension slurry, suspension slurry transported to the netting mechanism, the fibers in the wet state into the net and then reinforced into cloth.
Fifth, spunbond nonwoven
Spunbond nonwoven is in the polymer has been extruded, stretched to form a continuous filament, the filament laid into a network, fiber network and then after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement methods, so that the fiber network into a nonwoven fabric.
Six, meltblown nonwoven
Meltblown nonwoven process: polymer feeding - - melt extrusion - - fiber formation - - fiber cooling - - into the network - - reinforcement into cloth.
Seven, needle punched nonwoven
Needle punched nonwoven is a dry nonwoven, needle punched nonwoven is the use of felting needle puncture, the fluffy fiber mesh reinforced into cloth.
Eight, sewing nonwoven
Sewing nonwoven is a dry nonwoven, sewing method is the use of warp knitting coil structure on the fiber mesh, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.) or a combination of them to reinforce the nonwoven fabric.
Third, nonwoven fabrics affect the growth rate of factors -
All the factors affecting the growth of man-made fibers can be more or less to man-made fibers as raw materials for textiles have a certain impact, which has the greatest impact on nonwoven textiles.
Population growth has less of an impact on nonwovens than on other textiles used in apparel. However, population growth is also an important factor when considering the important use of nonwovens in baby diapers.
The partial replacement of natural fibers will have a greater impact on textiles, but not on nonwovens, which are largely dependent on man-made fibers.

Question 6: What is the difference between the nonwovens industry and the textile industry To know the difference between the nonwovens industry and the textile industry, it is necessary to look at the nonwovens and textiles for difference. Nonwoven raw materials are man-made fibers, composite glue, processing close to the principle of paper, fibers bonded together with glue. At this stage can not be used for clothing, bedding, etc., high-end uses.
The raw material of textiles is cotton, or man-made fibers. It is prepared with textile machinery, there is no glue component. Used for clothing, bedding and other human contact purposes.
Simply put, the raw materials, equipment, processes, uses are different.
Question 7: geotextile belongs to what industry geotextile, also known as geotextile, it is made of synthetic fibers through the needle punching or weaving of permeable geosynthetics. Geotextile is a new material geosynthetics one of the finished product for the cloth, the general width of 4-6 meters, the length of 50-100 meters. Geotextile is divided into spun geotextile and non-woven filament geotextile.
Geotextile manufacturers, for your answer
Question 8: Nonwoven fabrics belong to the plastic chemical industry or textile industry Nonwoven fabrics belong to the textile industry
Question 9: What is the difference between spun and nonwoven fabrics? What are the advantages and disadvantages of each? What are the advantages and disadvantages of each? I hope the people patiently answer. Nonwoven refers to the use of fibers directly using adhesive, hot melt, mechanical entanglement and other methods of forming the cloth, (not through the textile process) the manufacturing process is relatively simple, low cost. Mostly used in industry and lining. Because it is a kind of fabric without spinning and weaving and the formation of fabrics, just the textile staple fibers or filaments for directional or random support columns, the formation of fiber network structure, and then use mechanical, thermal bonding or chemical methods of reinforcing and become. Simply put: it is not interwoven by a one-by-one yarn, knitted together, but the fibers directly through the physical method of bonding together, so when you get your clothes in the sticky claim, it will be found that is not extracted by a single thread. Nonwovens break through the traditional textile principles, and has a short process, fast production speed, high yield, low cost, wide range of uses, raw material sources and other characteristics.
Its main uses can be broadly divided into: (1) medical and health care fabrics: surgical gowns, protective gowns, disinfectant wraps, masks, diapers, women's sanitary napkins, etc.; (2) home decoration fabrics: wallpaper, tablecloths, bed sheets, bedspreads, etc.; (3) with the installation of fabrics: lining, adhesive interlining, wadding, shaping cotton, a variety of synthetic leather backing, etc.; (4) industrial fabrics: filtering materials, insulating materials, cement, packaging bags, geotextiles, packages, and other synthetic leather. Packing bags, geotextiles, wrapping cloth, etc.; (5) agricultural cloth: crop protection cloth, rice planting cloth, irrigation, insulation curtains, etc.; (6) other: space cotton, thermal and acoustic insulation materials, linoleum, cigarette filters, bags and bags of tea bags, etc..
Problem ten: nonwoven belongs to the textile should not belong to, nonwoven is a kind of spinning and weaving and the formation of fabrics, just textile staple fibers or filaments for directional or random bracing, the formation of the fiber network structure, and then mechanical, thermal bonding or chemical methods of reinforcement and become. It is a nonwoven fabric, but can be used in clothing, medical, industrial and other industries. Such as masks, adhesive lining, protective film, filtration materials, artificial leather backing and so on.
