(3) Laying: step (2) the carded raw materials enter the laminating machine, the process parameters and key technologies of the laminating process: the number of layers of cross-lapping should be appropriate, in order to avoid cross marks, the fibers coming out of the carding machine The edge of the net should not be too neat, a little plush is good.

The use of cross-lappers is easy to generate static electricity during production, and the operator should pay special attention to it. Serious static electricity must occur, and the speed of the vehicle should be appropriately reduced.

The process parameters of the web-laying machine: the number of web-laying layers is 4-8 layers, the feeding machine width is 2500m, the web width is 2500-3000m, the feeding web weight is 18-60 g/m ² , the web-laying speed and carding machine The speed is synchronous, 39~65m/min, the width of the net-laying machine is 2.60-3.00m, and the speed of the net-laying machine is 6.2~8.0m/min;

(4) Drafting: Step (3) Raw materials after web laying are drawn into fiber webs by drafting machine. The size of the draft multiple is controlled at 1-2 times.

Process parameters and key technologies of the spunlace process: spunlace pre-wetting can compact the fluffy fiber web, remove the air in the fiber web, strengthen the fibers in the fiber web to effectively absorb the energy of the water needle, and improve the fiber entanglement effect. Fiber tangles are tighter.

Spunlace is the use of high-pressure jet water jets to spray the fibers laid on the trawl net, so that the fibers in the fiber net are subjected to jets in different directions, so that the fibers are entangled with each other, so as to achieve the purpose of consolidating the fiber net. It affects the strength, feel and surface shape of the product. Before the main puncture, pre-wet treatment should be used to strengthen the entanglement between the fibers. After high, then lower, to ensure that the fiber web can absorb energy well and low, and improve product quality.

As the spunlace pressure increases, the greater the high-pressure spunlace energy per unit area of the fiber web receives, the more fibers are entangled, the entanglements are tight and firm, the fiber entanglement effect is better, and the strength of spunlace products increases. When the spunlace pressure is moderate, the spunlace pressure should be adjusted in time according to the weight of the product, otherwise, when the spunlace pressure is too high, the fibers will move and directly affect the quality of the product. When the high-pressure water jet impacts the fiber web, the fiber web is subjected to the jet impact force of the high-pressure and high-speed water jet and the rebound water flow force of the trawl curtain, and the market contact is the best, and the strength of the spunlaced cloth increases.

The function of the conveying mesh curtain is to support and convey the fiber mesh into the spunlace area. During spunlace, the mesh curtain reflects the high-pressure water needle, participates in the reinforcement of the fiber mesh, and can effectively filter water and exhaust air. Through the mesh number and pattern changes of the net curtain structure, the finished product forms a certain appearance effect. As the conveying speed increases, the fiber web per unit area receives high-pressure spunlace for a shorter time, and the smaller the energy received, the less tightly the fibers in the fiber web are entangled, which will lead to a decrease in the strength of the spunlace product.

(6) Step (5) The spunlace-strengthened fiber web is dried with a dryer. The dryer uses hot oil to circulate inside the dryer, and heats the surrounding air through the emitted heat. With the help of a circulating fan The role of negative pressure is generated around the drying cylinder to form hot air for convective heat transfer drying to complete the purpose of drying. During the drying process, reasonable temperature, wind speed and small draft ratio should be adopted to ensure stable drying quality. Process parameters of the dryer: drying temperature 110~158℃, speed 12.6~28m/min, fan speed 1650~1850r/min, moisture regain 126~139% in the machine, moisture regain 17.87~19.41% in the machine;

(7) Step (6) The fiber web after drying is wound by a winding machine. The process parameters and key technologies of the winding process: the winding operation method must be strictly implemented, the patrol inspection should be strengthened, and the problems found should be solved in time. Do a good job of cleaning the site, and regularly check the equipment to keep the equipment in good condition. Carry out slitting and winding processing according to requirements, specifications, standards, etc., to ensure that the appearance, width and roll length meet the requirements.

Process parameters of winding machine: speed 12.8~28.6m/min, winding length 400~1000m/roll, winding diameter 400~950mm.
