Problems solved by technology
[0002] The non-trace dry fabric is mainly used in the drying area in the production process of anti-counterfeiting paper. Because the raw materials, manufacturing and processing equipment and processes used by the product manufacturers are very different, there are many problems in the actual use process, the effect is very unstable, and it cannot meet the requirements of small deformation. , high stain resistance, long service life, and no network marks on the paper surface

Embodiment Construction
[0035] A production process of a non-trace dry web for anti-counterfeiting paper, comprising the following steps:
[0036] (1) Purchase of raw materials
[0037] Purchase German high-quality monofilament according to the model, quality and quantity according to the requirements of the production plan;
[0038] (2) inspection
[0039] According to the requirements of the production plan, the indicators such as wire diameter, heat shrinkage, tensile strength, acid and alkali resistance are inspected item by item, and according to the specific production requirements, random inspections and full inspections are carried out in batches. The inspection indicators of this product are as follows:
[0040] Warp: Ф0.45mm, tensile strength: 500 N / mm 2 , heat shrinkage value: 6%,
[0041] Weft: Ф0.65mm, tensile strength: 450N / mm 2 , heat shrinkage value: 3%;
[0042] (3) warping
[0043] The tension of each monofilament is required to be uniform, warping speed: 50m / min, tens...

Abstract
The invention discloses a production process for a traceless dry net for security paper. The production process comprises steps of raw material purchase, wire examination, warping, head passing, net weaving, net checking, one-time sizing, net cutting, connection opening manufacture, finished product inspection, packing storage and the like. According to the production process for the traceless dry net for security paper, German hydrolysis resistant monofilaments are used as warps and wefts, and surfaces of the warps and the wefts are subjected to special treatment, so that the dry net is capable of resisting stains and high temperatures, not prone to age, and long in service life; the produced dry net for security paper is compact in structure, high in surface flatness, and good in drying effect, and wire marks do not leave on the surface of finished security paper.
Description
technical field [0001] The invention relates to a drying net, in particular to a production process of a traceless drying net for anti-counterfeiting paper. Background technique [0002] The non-trace dry fabric is mainly used in the drying area in the production process of anti-counterfeiting paper. Because the raw materials, manufacturing and processing equipment and processes used by the product manufacturers are very different, there are many problems in the actual use process, the effect is very unstable, and it cannot meet the requirements of small deformation. , high stain resistance, long service life, and no web marks on the paper surface. For this reason, our company attaches great importance to customer demands, invests a lot of money, organizes technical forces to go deep into the customer's production site, and carefully summarizes, analyzes and studies the characteristic requirements and practical problems of the anti-counterfeiting paper dry net in the specifi...
