A warp self-binding forming fabric, relates to the technical field of forming fabrics for paper making, comprises a face layer, a bottom layer, and connection lines. The face layer is a plain structure formed by alternately interlacing face warps and face wefts. The bottom layer is a satin structure formed by alternately interlacing bottom warps and bottom wefts. The connection lines are arranged in pairs, and connect the face layer and the bottom layer in the warp direction. The connection lines are alternately interlaced in the upper-layer net and the lower-layer net regularly, so that the upper-layer net and the lower-layer net are connected together, the relative twisting movements and slides do not occur, thereby eliminating internal abrasion. The forming fabric has the advantages of stable dewatering performance, short dewatering time, uniform mesh sizes, prevention of internal abrasion of the three-layer net, longer service life and easiness in cleaning.
A: A paper diaper having a new type of absorption layer and processing method therefor. The paper diaper comprises a surface layer (1), an absorption layer, a bottom layer (5), and waist stickers. The absorption layer is between the surface layer (5) and the bottom layer (5). The absorption layer has multiple sewing threads (7) interpenetrating therein for dividing the absorption layer into and fastening multiple web structures. The sewing threads can penetrate the surface layer (1), and separately connect the surface layer (1) and the bottom layer (5), thereby forming an integral body. The absorption layer can comprise a fluff pulp layer (3), a dispersion layer (2) thereabove, and an absorbent paper layer (4) therebelow. The sewing threads (7) can penetrate the fluff pulp layer (3), and separately connect the dispersion layer (2), and the absorbent paper layer (4). The fluff pulp layer (3) can be provided with multiple fiber coagulation points. The paper diaper is simple in structure, economic, practical, safe, sanitary, and comfortable. The absorption layer is not easy to deform and fracture. The processing method has a simple production process and high production efficiency.
B: A diaper pad having a new type of absorption layer and processing method therefor. The diaper pad comprises a surface layer (1), an absorption layer, and a bottom layer (5). The absorption layer is between the surface layer (1) and the bottom layer (5). The absorption layer has multiple sewing threads (7) interpenetrating therein for dividing the absorption layer into and fastening multiple web structures. The sewing threads can penetrate the surface layer (1), and separately connect the surface layer (1) and the bottom layer (5), thereby forming an integral body. The absorption layer can comprise a fluff pulp layer (3), a dispersion layer (2) thereabove, and an absorbent paper layer (4) therebelow. The sewing threads (7) can penetrate the fluff pulp layer (3), and separately connect the dispersion layer (2), and the absorbent paper layer (4). The fluff pulp layer (3) can be provided with multiple fiber coagulation points. The diaper pad is simple in structure, economic, practical, safe, sanitary, and comfortable. The absorption layer is not easy to deform and fracture. The processing method has a simple production process and high production efficiency.
C: An industrial fabric, which relates to the technical field of engineering textiles. The industrial fabric is a mesh woven from warp yarns made of monofilament materials and weft yarns made of monofilament materials. The warp yarns are of a double-layer structure. One of warp yarn basic units comprises four sub-units, two sub-units being located on an upper layer, the other two sub-units being located on a lower layer. The warp yarns on the upper layer and the warp yarns on the lower layer are in a vertical overlapping relationship, wherein at least two units comprise two parallel narrow warp yarns (1t, 2t). Upper warp yarns and lower warp yarns, namely front warp yarns and back warp yarns (3b, 5b, 6b), are identical in texture structure, or one surface is identical to the other surface after rotating by 180 degrees. The industrial fabric is stable in structure and good in overall consistency, does not deform easily, and is durable. The upper surface is good in flatness, the surface is free from defects, and the quality and intensity of the fabric are improved, such that the quality and efficiency of paper making are guaranteed, the rejection rate is reduced, and the cost is greatly reduced. The industrial fabric is applied to paper making meshes, can also serve as a conveyor belt, and is widely applied to the industries such as paper making, chemical engineering, medicine and machinery.
D: Disclosed is a skid-resistant carpet rubber mat layer. The skid-resistant carpet rubber mat layer comprises a bottom layer, which is a skid-resistant water-repellent layer (5), and an upper layer, which is a bonding layer (4), and the bonding layer (4) is a single-face fabric provided with a plurality of monofilament protrusions. The bonding layer (4) is a single-face fabric made of monofilaments with a unit of 20D or above and provided with protrusions, or a single-face structure layer formed by splitting the middle of a three-dimensional mesh cloth structural layer, and the three-dimensional mesh cloth structural layer is composed of an upper-layer warp-knitted mesh fabric and a lower-layer warp-knitted mesh fabric, and a plurality of terylene, polypropylene or nylon monofilaments that are vertically arranged in the middle and are used for connecting the upper-layer warp-knitted mesh fabric and the lower-layer warp-knitted mesh fabric. The skid-resistant carpet rubber mat layer can be used in combination with various carpet surfaces, and the bonding strength is moderate, such that the situation of the carpet surface being damaged during detaching due to excessive bonding force is avoided, and the situation of the carpet surface being prone to displacement and upwarping due to a bonding force being too low is also avoided. Meanwhile, the skid-resistant carpet rubber mat layer has advantages such as being capable of being rolled, capable of being folded, capable of being washed by a machine, and being convenient to lay and convenient to transport.
