The non-woven fabric for an alkaline battery separator is a dicarboxylic acid component containing 60 mol% or more of the dicarboxylic acid component and an aliphatic dicarboxylic acid component, and 60 mol% or more of the diamine component is a fat having 6 to 12 carbon atoms. A nonwoven fabric for an alkaline battery separator comprising a semi-aromatic polyamide fiber composed of a diamine component of an alkylene diamine and an ethylene-vinyl alcohol copolymer fiber, wherein the nonwoven...
The special solvent is used, which can not dissolve the high polymer at normal temperature, and dissolves under high temperature and high pressure. After the raw liquid flows out of the spinneret, the solvent suddenly evaporates (flashes) to form fibers. For example, flash spinning can be carried out using a solution of polyethylene in chloroform. The solvent spinning process is a patented technology developed by Dupont Company of the United States. It can also be called flash method, flash...

At present, most of China's fabrics are divided into knitted and woven. A woven fabric is a fabric formed by interlacing warp and weft perpendicularly to each other. For knitted fabrics, the yarn or filament is formed into a coil by a knitting needle, and the coils are then sleeved together. However, there are still many people who do not distinguish between knitted fabrics and woven fabrics, so this article will introduce the difference between the two. First, woven fabric The fabrics of...
Wet-laid nonwoven technology is a new technology for producing non-woven products or paper-bond composites using papermaking equipment and technology. It has been widely adopted in countries with developed economies such as Japan and the United States, forming a large-scale industrialization advantage. The technology breaks through the traditional textile principle, avoids the complicated labors such as carding, spinning and weaving, which has high labor intensity and low production efficiency,...
It is often said that non-woven fabrics are environmentally friendly and are now people's green lifestyle. What kind of process is used to make non-woven fabrics? The common manufacturing process of non-woven fabrics. Some holes in screen printing screens can penetrate ink and miss the print on the substrate; the rest of the mesh on the plate is blocked and cannot penetrate the ink. It is formed on the substrate Blank, with the silk screen as the support, stretch the silk screen on the...

The project provides a double-layer water-absorbing moisture-conducting non-woven fabric and a preparation method thereof, which include an inner layer having a hygroscopic property compounded by a hot-rolling compound method and an outer layer that leads to moisture absorbed in the inner layer. The inner layer is prepared from components mainly including the following weight distribution ratios: natural vegetable fiber 10-50 parts, polypropylene resin pellets 45-80 parts, compatibilizer 1-6...
The exact name of non-woven fabric should be non-woven fabric, or non-woven fabric. Because it is a fabric that does not require spinning and weaving, it is just oriented or randomly braided short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. The characteristics of non-woven fabrics · Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production...

One way to ensure the cleanliness of materials in the production of nonwoven fabrics is to use a filtration system. This article introduces two German-made filters. When they replace the filter, the process does not fluctuate. At the same time, they can be directly produced using recycled materials to reduce costs. In the process of spunbond production of nonwoven fabrics, the processes of fiber drawing and nonwoven fabric formation are combined into one. The polymer raw material enters the...
