Problems solved by technology

Natural plant fiber materials have been widely used in all aspects of people's daily life due to their rich resources, renewable, non-toxic, non-polluting, degradable and other advantages, such as the use of mountain palm silk, bamboo silk, palm silk, etc. However, this kind of mattress filling material generally needs to use adhesives to bond the scattered plant fibers together. Therefore, the developed products contain toxic substances such as formaldehyde, which is not conducive to human health.

Embodiment 1

[0062] A kind of screening method of sponge gourd sponge large sheet raw material, carry out as follows:

[0063] ①First choose a density of 19Kg / m 3 -30Kg / m 3 The loofah is the primary raw material;

[0064] ②Wash the selected loofah raw material, dry it in the sun, and control the water content within 7%; then cut off the two ends to obtain the loofah column before flattening, such as Figure 7 , 8 Shown; Then it is cut along the loofah shaft side, after removing the core material 52; Flatten the sapwood 51; The loofah columnar body 5 in the flattening process, as Figure 9 , 10 shown.

[0065] ③Screen the sapwood again, and select the flattened sapwood of loofah with a gram weight ≥ 160g / ㎡ as the final large sheet of loofah sponge

[0066] raw materials.

[0067] During specific implementation, the density of the loofah primary raw material is screened by wind; then the primary raw material density after winnowing is further sampled by 1% to check whether it is quali...

Embodiment 2

[0070] A kind of luffa sponge large sheet processing method one, carry out as follows:

[0071] 1. Obtain the loofah sponge large sheet raw material as mentioned above;

[0072] ②Pave the selected flattened loofah sapwood in the same direction, with the smooth surface of the outer layer of the loofah facing up and the surface of the inner layer facing down. The density and grammage of the material shall be consistent, and the laying shall be 960g-1800g per square meter;

[0073] ③ Pre-press the laid flattened loofah sapwood, set the height to 3cm, hold the load for 2 minutes, and unload;

[0074] ④Repeat step ③, 2 times;

[0075] ⑤ quilting the pre-pressed layered loofah sap material, the distance between the quilting lines is 150-200mm, and the thickness is 3cm to obtain a large sheet of loofah sponge;

[0076] ⑥ Trim the large sheet of loofah sponge that has been quilted according to the size specifications;

[0077] ⑦ Obtain the final loofah sponge large sheet, small he...

Embodiment 3

[0079] A large loofah sponge sheet processing method two, carried out as follows:

[0080] 1. Obtain the large sheet raw material of loofah sponge as mentioned above;

[0081] ②Pave the selected flattened loofah sapwood in the same direction, with the smooth surface of the outer layer of the loofah facing upwards and the surface of the inner layer facing downwards; 1. The lower layer of flattened loofah sapwood is staggered and stacked, and a thin layer of skin-core low-melting point polylactic acid fiber is laid between the layers; and 960g-1800g of loofah sapwood is laid per square meter;

[0082] ③Fix the paved loofah sponge blank at a height of 3cm and heat press at a temperature of 115°C for 2 minutes;

[0083] ④ Cool the large sheet of hot-pressed loofah sponge to room temperature and let it stand for 24 hours;

[0084] ⑤ Trim the above-mentioned large loofah sponge sheet according to the size specifications, and obtain the final large loofah sponge sheet, small head are...

Abstract

The invention discloses a healthy and environment biomass loofah sponge partitioned mattress, a screening method of loofah sponge raw material, and a sheet material processing method. The mattress comprises an upper layer and a lower layer. The upper surface, lower surface, and edges of the comfortable layer of the upper layer are covered by a fabric composite layer, bottom lining, and surrounding edge, and the bottom of the surrounding edge is provided with an extension part and a connection member. The core layer of the lower layer is composed of large loofah sponge sheets, spliced loofah sponge sheets, large loofah sponge coated sheets, and core cover composed of spliced loofah sponge sheets, the bottom surface and surroundings of the core layer are covered by a lower fabric composite layer and surrounding edge, the top of the surround edge is correspondingly provided with an extension par and a connection member, and the upper layer and lower layer of the mattress are connected by the connection members. The loofah sponge edging with a density of 15 to 30 kg / cm3 is taken as the raw material. A flattening technology, a glue-fee low-temperature hot press (cold press) technology, and a quilting technology are used to prepare natural biomass loofah sponge; the technologies are environment-friendly and ecology-friendly; moreover, the natural spacial network structure of loofah sponge is maintained, and overcome are the shortages that in the prior art, after processing, the breathability of loofah sponge is reduced, and the processed loofah sponge is prone to get damp and deformed.

Description

technical field [0001] The present invention relates to a kind of plant fiber mattress, especially utilizes loofah natural plant fiber space network structure and high air permeability, high moisture absorption and dehumidification, and excellent properties such as low carbon, environmental protection, regeneration, promoting blood circulation and anti-inflammation, etc., through flattening Technology and glue-free low-temperature hot pressing or cold pressing process, the pure natural biomass loofah sponge material is obtained, and the health partition mattress developed by using this material can meet the quantitative support and comfort requirements of people of different shapes and weights . Background technique [0002] Mattresses currently on the market mainly include sponge mattresses, latex mattresses, spring mattresses, palm mattresses, etc. Among them, the raw materials of natural latex mattresses are limited, while the raw materials of synthetic latex mattresses a...
