Product weight range is wide. PET spunbond spinning adopts Non-woven Lining positive pressure drafting, and the weight range of the produced non-woven fabric can reach , and the weight of PET spunbond hot-rolled fabric is about.PET spunbond needle punching The cloth is distributed between. The general domestic production line of PP spunbond non-woven fabric imitating the Laifen 2 type adopts negative pressure drafting and suction under the condensation water curtain, and is equipped with a fan. The production of thicker products will lead to insufficient drafting of the primary fiber. Can not produce products above. Now, Refine 3 and 4 models have added a positive pressure drafting device, and the product weight range will be improved. The development of new products of polyester non-woven fabrics in this field includes two aspects: one is the new development of existing materials in the clothing industry; the other is the development of new materials in the clothing industry. Second, develop new non-woven fabrics. SMS nonwovens are spunbonded and meltblown composite products.
They have the advantages of high strength, good filtering performance, no glue, and non-toxicity. They play an important role in the field of medical and industrial filter materials. The most recent application is SMS breathable, non-toxic It produces fiber dust and prevents the body from having the characteristics of particles exchanged with the outside world. It is used in pharmacy, bioengineering, photoelectric processing, electrical components and chips and other production environments that require a high degree of cleanliness. Spunbond non-woven fabrics are made of high-strength continuous filaments, occupying a large part of the disposable protective clothing market. The latest development is the addition of special additives or finishing agents in the production of spunbond non-woven fabrics, so that the products have Flame retardancy, antistatic property In the development of new fibers, water-soluble non-woven fabric is an environmentally friendly product, and its application is gradually expanding.
The spunlace non-woven fabric produced by water-soluble polyvinyl alcohol fiber is a good material for the production of anti-radiation and anti-pollution clothing. In order to increase the protective effect, it can also be combined with a water-soluble film to increase the barrier performance of the protective clothing. In addition, in the use of new fibers, foreign countries have also developed non-woven fabric production processes by adding super absorbent fiber technology. This SAF-containing non-woven fabric has particularly good soft hand feel and water absorption. When used as underwear, it can quickly absorb human sweat and increase the micro-environment comfort between clothes and human body.Flexible production process adjustment. The spinning box of the PET spunbond production line uses multiple independent metering pumps to measure the melt. Each metering pump supplies the melt to a specified number of spinning assemblies. Therefore, according to the customer's order requirements, the production of the metering pump can be stopped/opened, and then the baffle of the cycloidal needle wheel can be adjusted to produce semi-finished products with different widths, and the width can be adjusted between 2.0~3.4m.
In addition, when some position indicators of the semi-finished product do not meet the standard, the corresponding spinning components can be adjusted. If the air permeability is insufficient, the spinning component with fewer holes in the spinneret can be replaced to increase the air permeability of the fabric. Even the air pressure of each drainage tube can be adjusted to achieve uniform physical performance across the entire width. The PP spunbond method generally uses the entire spinning process, and the width cannot be adjusted during the production process, resulting in waste and waste. Moreover, the product index produced is not uniform, and the adjustment method is monotonous. The product has strong lateral strength. The PET spunbond method adopts the cycloid molding method. The pendulum swings back and forth at a frequency of 750 Hz, and the high-speed drawn fiber is hit by the mesh curtain laterally. Because the mesh curtain moves forward and the fibers are interlaced on the diagonal, the PET spunbond fabric has strong strength and vertical and horizontal directions. The power ratio can basically reach 1:1. PP spunbond generally uses venturi tube debris, which is generally not high in strength, and has a large strength ratio in the vertical and horizontal directions. PET fiber has high temperature resistance and wear resistance, and its mechanical strength is greater than PP fiber.
