A non-woven fabric preparation process that can replace natural veneer
A preparation process and technology of natural veneer, which is applied in the direction of wood layered products, non-woven fabrics, textiles and papermaking, etc., can solve the problems of inability to achieve the aesthetic effect of furniture panels, the inability to meet the requirements of bonding strength, and poor aesthetics of the panels. Small longitudinal and transverse deformation, reduced formaldehyde content, and good wrinkle resistance

Problems solved by technology
However, due to the great difference between the physical properties (cohesiveness, strength, water resistance, etc.) poor overall aesthetics
When the non-woven fabric is bonded to the substrate by water-based glue, the adhesion is poor (there is a great difference in the water absorption and cohesion between the non-woven fabric and natural wood), which cannot meet the bond strength requirements. After the amount of water-based colloid is increased , the colloid is easy to pass through the non-woven fabric and the water-based colloid becomes glassy after solidification. The covering performance of the decorative paper itself is much worse than that of the coated paper. From the outside, there are various glue spots on the entire surface of the board, which cannot achieve the aesthetic effect of the furniture board.

Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0025] Such as figure 1 and figure 2 A kind of non-woven fabric preparation process that can replace natural veneer shown, comprises the following steps:
[0026] S1, the preparation of base fiber web: prepare fiber according to the following parts by weight: 5-10 parts of polypropylene long fiber, 10-15 parts of viscose fiber, 6-12 parts of bamboo fiber, 3-7 parts of polyester fiber, the above fiber After mixing and opening, carding is used to form a base fiber web 1;
[0027] S2: Front and back spunlace: pull the base-level limit net to the spunlace area for front and back spunlace;
[0028] S3: Squeezing and drying: the spunlaced fiber web is dried after being squeezed by a liquid-squeezing machine;
[0029] S4: One-time melting: the dried semi-finished non-woven fabric is drawn to the first melting area, and the upper and lower spraying head...

Abstract
The invention relates to the technical field of non-woven fabric manufacturing, and discloses a preparation process and application of a spunlace non-woven fabric in which the shell replaces natural veneer, including the following steps: S1, preparation of the base fiber web; S2: positive and negative spunlace; S3 : rolling liquid drying; S4: primary spray melting; S5: preparation of barrier layer; S6: secondary spray melting; S7: hot rolling forming. The non-woven fabric prepared by the above process can be used instead of natural veneer in the field of furniture boards, and the formaldehyde content of the prepared furniture boards is significantly reduced, which is more energy-saving and environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of non-woven fabric manufacturing, in particular to a preparation process of a spunlace non-woven fabric that can replace natural veneer. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers, and are called cloth because of their appearance and certain properties. Non-woven fabrics have many advantages such as moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Non-woven fabrics are simple to manufacture, low in cost, and very widely used widely. Non-woven fabrics are widely used, and common non-woven fabrics are used for masks, wet wipes, mask substrates, etc. [0003] At present, non-woven fabrics are hardly used in the field of furniture boards. Some furniture boards usually use technological wood (a kind of man-made comp...
