[0029] Example 1

[0030] like Figures 1 to 3As shown, the present invention provides a Z-shaped fiber spring pad core, comprising: a support plate 1; a plurality of support bars 2, arranged above the support plate 1, with mounting grooves 21 formed between the support bars 2; a plurality of bag springs 4, arranged one-to-one in the mounting grooves 21; and a panel 3, arranged above the support bars 2. The support bars 2 comprise an upper cotton portion 201, a middle cotton portion 202, and a lower cotton portion 203, wherein the upper cotton portion 201 and the lower cotton portion 203 sandwich the middle cotton portion 202. The middle cotton portion 202 comprises a plurality of stacked cotton strips, the top and bottom of which are connected to the upper cotton portion 201 and the lower cotton portion 203, respectively. The cotton strips are arranged at an angle, and form a "Z" shape with the upper cotton portion 201 and the lower cotton portion 203.

[0031] The utility model provides a Z-shaped fiber spring cushion core, a mattress and a sofa. The bag spring 4 is embedded and fixed between a supporting plate 1, a panel 3 and a support bar 2. The support bar 2 is a Z-shaped elastic cotton structure. While ensuring the effect of elastic force, there is no noise, no glue is used, no formaldehyde is contained, and it is environmentally friendly.

[0032] In some embodiments, as Figure 1 As shown, a frame layer 5 is further provided above the panel 3, and the frame layer 5 is provided with a hollow portion 51. The hollow portion 51 is filled with a cushioning material. The cushioning material includes latex, animal hair, or cotton.

[0033] In some embodiments, the support strip 2 comprises polyester fiber and functional elastic fiber. Specifically, the production process of the support strip 2 is as follows: polyester fiber, functional elastic fiber, and low-melting-point fiber are blended and loosened, then fed to a carding machine, where they are combed into a fiber web, which is then fed to a flat lapping machine. The flat lapping machine stacks the fiber webs layer by layer, which are then fed to a pressing roller for rolling. After the multi-layered fiber webs are thinned, they are fed to a needling machine. After the needling is completed, they are fed to an upright swing lapping machine, where the cotton layer structure is changed into a Z-shaped structure, and finally fed to an oven for heat pressing and cooling to form the webs.

[0034] In some embodiments, the support plate 1 comprises cotton substitute or jute fiber cotton, and has a thickness of about 10-30 mm.

[0035] In some embodiments, the panel 3 includes palm-replacement cotton, bamboo fiber cotton, or functional fiber cotton, and has a thickness of about 3 to 10 cm.

[0036] The production process of the entire Z-type fiber spring cushion core is as follows: place a support plate 1 made of substitute brown cotton or jute fiber cotton, arrange support strips 2 on the support plate 1, arrange the support strips 2 and independent bag springs 4 together, and then cover with a panel 3 made of substitute brown cotton or bamboo fiber cotton or functional fiber cotton, sew them together, and finally use a hot melt process to heat-melt the frame layer 5 and the panel 3 together.
