The invention discloses a stone texture-imitated ceramic water permeable brick and a manufacturing method thereof. The ceramic water-permeable brick with the imitated stone texture sequentially comprises a green body backing material layer, a green body surface material layer, a ground glaze decoration layer, a pattern decoration layer, a surface glaze decoration layer and a functional glaze decoration layer from bottom to top, and when the ratio of the nominal length to the nominal thickness of the ceramic water-permeable brick is smaller than or equal to 4, the ceramic water-permeable brick is a water-permeable pavement brick, the splitting tensile strength is larger than or equal to 3.0 MPa; the permeability coefficient is greater than or equal to 1.0 * 10 <-2 > cm / s; when the ratio of the nominal length to the nominal thickness of the ceramic water-permeable brick is larger than 4 and the ceramic water-permeable brick is a water-permeable pavement slab, the breaking strength is larger than or equal to 3.0 MPa, and the water permeability coefficient is larger than or equal to 1.0 * 10 <-2 > cm / s. The water-permeable ceramic tile product provided by the invention is clear in texture, rich in pattern effect, optional in product color and capable of realizing color and texture representation of the existing stone.

[Problem] To provide a composition which can resolve the conflicting relationship between patternability, film formability, and high refractive index required for an optical waveguide-forming composition, and which can satisfy these requirements. [Solution] An optical waveguide-forming composition comprising: a fluorene skeleton-containing epoxy compound (A) of the following Formula [1]: (in Formula [1], L1 and L2 are each independently a naphthalenediyl group possibly having a substituent; and m and n are each independently an integer of 0 to 10); a monofunctional or bifunctional alicyclic epoxy compound (B); a monofunctional or bifunctional aromatic epoxy compound (C) different from the compound (A); and a photoacid generator (D), and an optical waveguide comprising a cured product of the optical waveguide-forming composition.

The present application relates to the technical field of warp knitted fabrics, and in particular to a three-jacquard composite interlaced jacquard warp knitted fabric, comprising a fabric body integrally woven by a double-needle-bed high-speed three-jacquard machine, the fabric body comprising a surface layer, a bottom layer, and an intermediate layer, the surface layer comprising a surface layer matrix, a first jacquard structure, and a second jacquard structure, the first jacquard structure being woven in the surface layer matrix, the second jacquard structure being woven in the first jacquard structure; the bottom layer being woven below the surface layer; the intermediate layer being woven between the surface layer and the bottom layer and being used to connect the surface layer and the bottom layer, the bottom of the intermediate layer being woven with a third jacquard structure; the first jacquard structure, the second jacquard structure, and the third jacquard structure together constitute an interlaced jacquard structure structure, enriching the jacquard effect and the pattern effect, and effectively improving the extensibility, physical properties, permeability, and breathability of the warp knitted fabric.

The application discloses a one-time pressing forming process of a multilayer composite material containing a functional structure and relates to the technical field of plate processing processes.The one-time pressing forming process comprises the following steps: S1, preparing a decorative layer, a fiber resin layer and a functional layer, printing UV temperature-resistant ink on kraft paper to obtain the decorative layer, and immersing fiber cloth or fiber silk in a resin solution to obtain the fiber resin layer; S2, laminating and flattening the decorative layer, the fiber resin layer and the functional layer, the fiber resin layer is symmetrically arranged on the two sides of the functional layer, the decorative layer is arranged on the side of the fiber resin layer away from the functional layer, at least one fiber resin layer is arranged between the decorative layer and the functional layer, and a laminated body is obtained; and S3, placing the laminated body in a mold, using a press to perform warm and pressurized forming, and allowing the resin solution to infiltrate to the surface of the kraft paper through the pores of the kraft paper, so that the decorative layer, the fiber resin layer and the functional layer form an integral whole. The process has the advantages of high bonding strength, difficulty in peeling, good pattern effect and greatly reduced production cost.

The invention provides a warp knitting jacquard fabric knitting method and a fabric thereof. According to the knitting method, a single-jacquard warp knitting machine with eight guide bars is selected; wherein the guide bars GB1, GB2 and GB5 act on the front needle bed and form a tatting-imitating surface layer by knitting tricot stitch and weft insertion stitch, and the guide bars GB3, GB6 and GB7 act on the rear needle bed and form a bottom layer by knitting tricot stitch and weft insertion stitch; jB4.1 and JB4.2 act on a front needle bed and a rear needle bed, and a jacquard layer is formed by knitting a chain stitch; the warp-knitted jacquard fabric obtained through the knitting method has the pattern effect of a tatting doup product, meanwhile, the knitted fabric is slightly elastic in the weft direction, good in foot feeling wrapping performance, free of elasticity in the longitudinal direction and good in product size stability, coils are not prone to loosening, and durability is excellent.
