Example 1
A preparation process of the functional non-woven fabric is shown in fig. 1, and comprises the following steps:
feeding: adding terylene and viscose fiber in sequence, wherein the proportion of the terylene to the viscose fiber is 65:35.
clearing: each production line mainly comprises three electronic weighing bale openers, a pre-opener, a large cotton mixer, two fine openers, two metal detectors and a pipeline type two-way cotton distributor. The electronic scale unpacking is carried out after polyester and viscose are weighed according to a set proportion, then the preliminary mixing is carried out, the fiber blocks in the raw materials are torn and loosened through the relative motion of a pre-opener middle machine, so that the density of the fiber blocks is reduced, various raw materials are further mixed through a cotton mixer, finally the fiber raw materials are beaten or the fiber layers are penetrated simultaneously through a fine opener beating machine part to carry out segmentation and carding, the bonding force among fibers is destroyed, and the aim of further loosening the fiber blocks is achieved.
Carding: the opened fiber is sent to a carding process through a closed pipeline, and the mixed fiber bundle is carded into a thin net composed of single fibers for laying and lapping and subsequent water jet reinforcement.
Lapping and drafting: the web fed from the carding machine is fed into an emergency cotton sucking and trimming device, and the thin web is laid into a web with a certain thickness and width, and the uniformity of the fiber layer and the consistency of the longitudinal and transverse strength are strictly controlled.
Preparing a water thorn solution: dissolving vitamin C and vitamin E in water at 30deg.C, stirring to dissolve thoroughly, and diluting with water at 15deg.C to obtain functional treatment solution with vitamin C and vitamin E concentration of 2%.
And (3) water jet: the fiber web is pre-wetted and then enters a water jet area, and a plurality of micro water jet streams are sprayed from water jet holes of a water jet plate of a water jet head and vertically irradiate the fiber web. The water jet displaces a portion of the surface fibers in the web and our formulation is sprayed into the surface, including vertical movement toward the opposite side of the web, and is deflected by the supporting curtain or drum to scatter at different orientations toward the opposite side of the web as the water jet penetrates the web. Under the dual actions of direct impact of water jet and rebound of water jet, the fibers in the fiber net displace, interpenetrate, intertwine and cohesion to form a plurality of flexible intertwining points, so that the fiber net is reinforced. In the water jet step, the number of the water jet heads is 8, the pressures of the first 5 water jet nozzles are 60bar, 70bar, 75bar, 65bar and 65bar in sequence, and the pressures of the last 3 water jet nozzles are 90bar, 95bar and 90bar. The adoption of 8 spray heads and the increase of the pressure of the last 3 spray heads can lead the stress of the fiber web to be more uniform, the non-woven fabric is better in networking, and the jacquard effect is better.
The functional aqueous solution was sprayed onto the web by variable frequency spray heads (24 spray heads per row) and was uniformly permeated into the web from the web surface by vacuum suction. The water used in the process is soft water, and the waste water generated in the water needling process is reused for production after being treated by reuse water engineering.
And (5) rolling and drying: in order to reduce the energy consumption of drying, the fiber web after vacuum suction is further rolled and dried, a pair of rollers are adopted for mutual extrusion, water in the middle non-woven fabric is rolled and dried, and the generated wastewater is recycled for production after being treated by recycling water engineering.
And (3) drying: the formed web was fed into a twin cylinder dryer and dried by hot air (135 c) generated by heating with natural gas to a moisture regain of 6.8%.
And (3) rolling: and (5) winding and rolling the non-woven fabric product by using an automatic winding machine, wherein the winding machine Ji Miding is long, the fixed length is automatically stopped, and the roll is automatically replaced.
