Factors influencing the effect of spunlace jacquard non-woven fabric pattern structure

Abstract: Introduced the production process of spunlace jacquard non-woven materials, the ratio of lead as raw material, spunlace pressure, total spunlace energy and non-matching, energy efficiency structure, drying temperature and winding draft speed ratio, etc. The influence of production process on the effect of product structure and its reasons are analyzed. Spunlace non-woven technology has developed rapidly in the past ten years, and the performance of spunlace non-woven materials has been continuously improved with the breakthrough of spunlace technology. The spunlace non-woven fabric process is to continuously spray the fiber web through a high-pressure water stream. Under the action of the water needle impact energy, the fibers in the fiber web move, shift, rearrange and entangle each other, so that the fiber web can be reinforced, thereby obtaining a certain Mechanical properties. The product has high strength, soft hand feeling, good drape, no chemical adhesives and air permeability, etc. When spunlace, the web is impacted by different energy water needles, and a non-woven material with a jacquard structure on the surface can be prepared. Compared with ordinary spunlace non-woven materials, this material has its unique properties, such as enhanced water absorption, fuller hand feeling, and better dust collection (holding) effect when wiping and cleaning. In order to improve these properties to the greatest extent, the relevant factors that affect the web pattern structure during the production process should be fully considered to obtain a plump spunlace jacquard structure with good shape retention. Each link in the production of spunlace jacquard non-woven materials has more or less influence on the shape-preserving effect of the final material cloth pattern. In order to obtain better performance of the final product, all links in the production should be reasonably Configuration and design to make the prepared spunlace jacquard non-woven material as close as possible to the design requirements to achieve the best use effect. (1) The spunlace jacquard non-woven fabric material made of fibers with low initial modulus and softer has clearer patterns. For example, the jacquard effect of spunlace jacquard non-woven fabric material made with full viscose fiber is better than that of full polyester. (2) The pressure design of the entangled spunlace head should be appropriate, otherwise it is not conducive to the formation of the subsequent spunlace; the pressure of the jacquard spunlace should be adjusted according to the surface density of different products; the specific spunlace pressure should be determined according to the fiber ratio. Conducive to the formation of patterns. (3) The unit energy of the spunlace jacquard should be selected in an appropriate range, and the ratio of the energy of the jacquard spunlace head to the total energy should be kept at a certain level. (4) The outermost sleeve structure of the drum directly determines the shape of the pattern, which can be designed according to requirements. (5) The drying machine should be a single-rotation drum hot-air penetration type to maintain the pattern structure. (6) Proper winding and stretching speed ratio has a positive effect on the maintenance of the final fabric pattern.
