Manufacturing technology of integrated formaldehyde-free plant fiber mattress

Abstract

The invention discloses a manufacturing technology of an integrated formaldehyde-free plant fiber mattress. According to the manufacturing technology of the integrated formaldehyde-free plant fiber mattress, in the lapping procedure, combed plant fiber mixed with polyester fiber is evenly and flatly laid to reach the thickness needed by a finished-product fiber mattress body of 1-5 cm, and a fiberlayer is formed; in the needling procedure, the fiber layer is conveyed to the space between an upper needle group and a lower needle group, the upper needle group moves downwards to puncture the upper surface of the fiber layer so as to penetrate into the fiber layer, the lower needle group moves upwards to puncture the lower surface of the fiber layer to penetrate into the fiber layer, needlesof the upper needle group and the lower needle group conduct reciprocating up-down movement for puncturing, the puncturing depth is larger than a half of the thickness of the fiber layer, so that thefiber in the filer layer is interlaced, mutually hooked and intertwined, and then a fiber layer of an integrated structure is formed. Since the fiber layer of the integrated structure is formed, the problem that in the prior art, the layers are separated because the layers are not interlaced, mutually hooked and intertwined is solved; and because a chemical fiber protective layer is additionally arranged, the upper surface and the lower surface of the fiber mattress are flatter, and the protective function on the fiber mattress is achieved.

Description

technical field [0001] The invention relates to a manufacturing process of plant fiber mats, in particular to a manufacturing process of formaldehyde-free plant fiber mats. Background technique [0002] At present, the ratio of coconut palm fiber and polyester fiber to make coconut palm mat is usually 3:2, and the maximum usage ratio of coconut palm fiber is 60%, while the price of polyester fiber is more than twice that of coconut palm fiber, which is difficult to reduce by traditional techniques The use ratio of polyester fiber makes it difficult to reduce the cost of coconut palm fiber mats. The proportion of coconut palm fiber is insufficient and its strength is not enough. Generally, the manufacturing process of coconut palm fiber board needs to be dried in an oven for 15 minutes, which makes the production efficiency low and increases the production cost. As people pursue health, coconut palm mattresses are becoming more and more popular among mattresses that are now c...

Problems solved by technology

The production of fiber mats through this process does not require glue and does not enter the oven, thereby simplifying the process, improving production efficiency, and reducing manufacturing costs. However, the products produced have been used for a long time, and customers have reported to us that the products have the following defects: The fiber layer of some products is delaminated
