Description

Technical Field

[0001] The utility model relates to a low-permeability digital printing fabric, and belongs to the technical field of digital printing fabrics. Background Art

[0002] Digitally printed fabrics are popular among consumers due to their diversity and exquisite patterns, and can enrich people's material life. Digitally printed fabrics can be used not only as clothing fabrics but also as home fabrics. In addition, due to the good hygroscopicity of cellulose fabrics, the printing slurry will penetrate to the other side of the cellulose fabric during digital printing. How to prevent the slurry from penetrating to the other side of the cellulose fiber fabric during digital printing has become a problem to be solved. In addition, cellulose fiber fabrics, especially natural cellulose fiber fabrics, are interwoven with short fiber yarns and are prone to pilling. How to solve the problem of cellulose fiber fabrics being prone to pilling has also become a problem to be solved. Utility Model Content

[0003] The utility model aims to provide a low-permeability digital printing fabric, so that the digital printing fabric is not easy to pilling, and the digital printing slurry is not easy to penetrate to the other side of the fabric.

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] Combination Figure 1 , this embodiment is described in detail. A low-permeability digital printing fabric involved in this embodiment includes a digital printing fabric layer 1 and a digital printing pattern layer 2; the digital printing fabric layer 1 is a cellulose fiber fabric; a water repellent is attached to the fiber surface of the cellulose fiber fabric. The cellulose fiber fabric is impregnated with a solution containing a water repellent, rolled to a specific liquid waiting rate and then dried to obtain a cellulose fiber fabric with a water repellent effect. When impregnated with a solution containing a water repellent, drying will cause the fiber surface of the cellulose fiber fabric to be attached with a water repellent. When the digital printing slurry is sprayed onto the surface of the cellulose fiber fabric, the digital printing slurry can be prevented from penetrating to the other side of the digital printing fabric 1 because the cellulose fiber has a water repellent effect.

[0020] The cellulose fiber fabric is formed by interweaving cellulose fiber parallel twisted yarns, and the cellulose fiber parallel twisted yarns include parallel twisted hemp fiber yarns, cotton fiber yarns and hot-melt filaments.

[0021] Furthermore, the hot-melt filament used is ES filament, which has a skin-core structure. The skin layer has a low melting point and will melt when heated to bond with adjacent fibers, thereby making the fabric less prone to pilling when used.

[0022] Embodiment 2

[0023] Combination Figure 2 , this embodiment is described in detail. The low permeability digital printing fabric involved in this embodiment is different from the first embodiment in that: the digital printing fabric 1 is compounded with a skin-friendly fabric layer 3 on the side away from the digital printing pattern layer 2 through a hot melt adhesive mesh.

[0024] Furthermore, the skin-friendly fabric layer 3 is interwoven with strands of silk fiber yarn and cuprammonium fiber yarn twisted together. The silk fiber yarn used in the skin-friendly fabric layer 3 has a good skin-friendly effect, and the cuprammonium fiber yarn used has a silk feel and a soft hand feel, thereby effectively improving the skin-friendly effect of the skin-friendly fabric layer 3.

[0025] Another difference from the first embodiment is that a radiation-proof fabric layer 4 is provided between the digital printing fabric 1 and the skin-friendly fabric layer 3 through a hot melt adhesive net. The radiation-proof fabric layer 4 is interwoven with strands twisted from copper-plated fiber yarns and silver-plated fiber yarns.

[0026] Embodiment 3

[0027] Combination Figure 3 , this embodiment is described in detail. The difference between the low permeability digital printing fabric involved in this embodiment and the second embodiment is that: the side of the digital printing pattern layer 2 away from the digital printing fabric layer 1 is compounded with a waterproof breathable membrane 5. The waterproof breathable membrane 5 used is a TPU microporous membrane. Since the waterproof breathable membrane 5 is located on the outside of the digital printing pattern layer 2, it can protect the digital printing pattern layer 2 and avoid damage to the digital printing pattern layer 2 due to friction.

[0028] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
