The three major fibers used in the production of nonwovens are polypropylene (62% of the total), polyester (24% of the total) and viscose (8% of the total). Between 1970 and 1985, viscose fiber was the most widely used in the production of non-woven fabrics. However, in the past five years, the application of polypropylene fiber and polyester fiber has begun to dominate in the field of sanitary absorbent materials and medical textiles. In the early days of nonwovens production, nylon was used...
Pulse plating is widely defined as intermittent current plating. Intermittent current refers to the forward current occurring at a certain time and the reverse current at another time. Since the beginning of the 50's, people have been engaged in the research of pulse electroplating, because the pulse current can make the coating crystal refinement, high bonding force, no porosity, so that the coating has a good physical and chemical properties. Pulse plating parameters According to numerous...

In the 2000-2005 China Textile Industry Science and Technology Development Project Guide, there are 15 projects related to the nonwoven fabric and industrial textile industry. Among them, the...
Non-woven fabrics can be divided into different according to the production process: 1. Spunlaced non-woven fabric: The high-pressure fine water flow is sprayed onto one or more layers of the fiber web to entangle the fibers with each other, so that the fiber web can be reinforced and has a certain strength. 2, heat-bonded non-woven fabric: refers to the addition of fibrous or powdered hot-melt bonding reinforcement material in the fiber web, and the fiber web is then heated and melted to cool...
For people who have little contact with machinery, they usually only see the rotation of large machinery. It should be a totally unfamiliar concept for bearings. However, the bearings play a vital role in mechanical movement. So, do you know what a needle roller bearing is ? The needle bearing is a roller bearing with a cylindrical roller, which is both thin and long with respect to its diameter. This kind of roller is called a needle roller. Now I will introduce the needle roller bearing model...
Kungong filter press teach you how to choose the frame filter filter diaphragm pump Gap pump flow: According to the volume of the plate-and-frame filter room, the moisture content of the dehydrated mud, and the concentration of the sludge before the plate frame, the amount of mud required for each dewatering operation of the plate frame is calculated.

1. Thermal bonding nylon nonwoven fabric The nylon non-woven fabric thermal bonding method is one of the largest varieties of nylon non-woven fabrics. Generally, it is mixed with other fibers by using pure nylon staple fibers or nylon fibers, and the fibers are connected to each other by a hot rolling process to form a flake material. The product has the characteristics of thin, soft, fine and elastic, and is a good base material for high-grade adhesive interlining. It is used for lining cloths...
The turf-specific non-woven fabric is a bio-specific polypropylene with no toxic or side effects on plants. The non-woven fabric is a fabric formed without spinning, and the woven short fibers or filaments are oriented or randomly stretched to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It has the characteristics of short process flow, fast production speed, high output, low cost, wide application and many sources of raw materials. Features and...
This is from the definition of non-woven fabrics. A fiber length to diameter ratio of more than 300 is a non-woven fabric, and the fibers of the tissue paper are too short. In fact, the nature is almost the same thing, the paper itself and the non-woven fabrics have an intersection. Wood pulp can also be made into a non-woven fabric, not determined by the material. For example, napkins are made of wood pulp, but they are also a kind of non-woven fabric.
One, MOSFET and other large pads can be punched on the back. One of the first situations is the need for vias on the pad, for example: In order to improve the heat dissipation of the MOSFET, we punched the MOSFET pad. Note: In this case, we need to evenly arrange the hole during the processing of the large pad via hole to ensure that the pad is evenly heated. Second, some small package resistors and capacitors, do not hit the hole in the pad. The resistors and capacitors of general labels...
There has always been a doubt: the capacitive inductance is 1/jwC, the large capacitance C is large, the high frequency w is also large, the impedance should be small, is not more suitable for filtering high frequency signals? However, the fact is: large capacitors filter out low frequency signals. Find the answer today as follows: The general 10PF capacitor is used to filter out high-frequency interference signals. The 0.1UF filter is used to filter out low-frequency ripple interference. It...
In HPLC analysis, the column packing particle size is small and easily blocked by foreign particles, so the sample and solvent need to be pre-filtered to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires the introduction of inorganic contaminants in sample preparation. Needle filters can be used in HPLC analysis and IC analysis to filter sample solutions as an important step in sample preparation....

Ramkumar and others at Texas Tech University believe that nanomaterials will be the future of production. They believe that non-woven fabrics (non-woven fabrics) play a role in the development of nanotechnology. The 1934 patented cellulose acetate fiber electrospinning technology is widely recognized as the basis of nanotechnology. Nanotechnology was first used in the electronics industry, and it has been adopted late. So far, there are not many applications. Donaldson's nanofiltration...
