PET Spunbond Nonwoven Fabric Of Environmentally Friendly Products

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Oct 24, 2017

Nonwovens as a new generation of environmentally friendly materials, breaking the traditional textile principle, with short process, production speed, high yield, PET Spunbond Nonwoven Fabric low cost and moisture, breathable, flexible, light, non-combustion, easy decomposition, Nature and many other features, is internationally recognized as the protection of the Earth's ecological environmental protection products.

Nonwovens widely used, such as medical and surgical clothing, protective clothing, disinfection cloth, home decoration with the wall cloth, tablecloths, industrial filter materials, insulation materials, cement bags, covered cloth, agricultural Of the crop protection cloth, irrigation cloth, and space cotton, insulation materials, oil absorption felt and so on.

Calcium carbonate as plastic commonly used inorganic powder filler material, can reduce the production cost, improve the dimensional stability of plastic products, PET Spunbond Nonwoven Fabric heat resistance, tensile strength, play astigmatism and extinction effect, improve the processing of plastic molding, With many other powder material does not have the advantages. So its use in the plastics industry is very extensive.

Calcium carbonate and talc, kaolin compared with the advantages of cheap, relatively high density, non-woven fabric in the production process are generally calcium carbonate-based, PET Spunbond Nonwoven Fabric to save costs and increase the weight or hardness of non-woven fabrics.

(1) the size of calcium carbonate and its distribution should be appropriate. In the process of melt spinning or spinning, if the selected calcium carbonate filler size is too large, PET Spunbond Nonwoven Fabric it will lead to the nozzle hole clogging, seriously affecting the production and performance; if the particle size is too small, prone to agglomeration, While increasing the cost, PET Spunbond Nonwoven Fabric so the granularity of calcium carbonate should be strictly screened.

(2) better dispersion. Because calcium carbonate is difficult to disperse evenly during the filling process, it is usually necessary to pre-disperse calcium carbonate (ie, to prepare calcium carbonate-filled masterbatch) before use, in order to achieve a better filling effect.

(3) the higher the whiteness the better.

(4) in some special products (such as medical, health supplies), the purity of calcium carbonate is high, silicon, iron and other elements of the compound to be as low as possible, harmful heavy metal elements to more stringent requirements.

Nonwovens as a new environmentally friendly materials, PET Spunbond Nonwoven Fabric its market prospects are very broad. Non-woven masterbatch demand for calcium carbonate will inevitably rise. The quality of calcium carbonate filled masterbatch directly affects the production of nonwovens. PET Spunbond Nonwoven Fabric In the future, with the development of the plastics industry, PET Spunbond Nonwoven Fabric the diversification and functionalization of the products are becoming more and more demanding. Therefore, in the process of filling the masterbatch, the requirements of the surface modification and mastering technology The higher the higher.
