伪装网的种类
Types of camouflage nets
（1）林地型伪装网：正面为南方春夏季节使用的伪装网面，由深绿中绿黄绿和沙土等 4 种颜色斑点组成，适应春夏植被生长茂盛背景；反面为秋冬季节使用的伪装网面，由深绿中绿黄土和褐土斑点组成，适应林地背景秋冬植被落叶枯萎和休眠季节或植被背景，近红外线反射率与其背景基调相适应。
(1) Forest type camouflage net: The front side is a camouflage net used in the southern spring and summer season, composed of four color spots: dark green, medium green, yellow green, and sandy soil, suitable for the background of lush vegetation growth in spring and summer; The reverse side is a camouflage net used in the autumn and winter seasons, consisting of dark green medium green loess and brown soil spots, suitable for forest background, autumn and winter vegetation withering and dormant seasons, or sparse vegetation background. The near-infrared reflectance is adapted to its background tone.

(2) Desert type camouflage net: The front is suitable for desert or loess plateau scenes with less vegetation, composed of shallow sandy soil, brown soil, and loess spots; The reverse side shows the camouflage network of the Gobi Desert landform, consisting of shallow sand, black stones, and dark green spots. The near-infrared reflectance is adapted to its background tone.
（3）雪地型伪装网：正面为全积雪伪装网面，为全白色；反面为部分积雪伪装网面，由白色黄土两种颜色斑点组成。白色伪装色在紫外光谱350 nm处的反射系数≥70%，白度≥90。
(3) Snow type camouflage net: The front is a full snow camouflage net surface, which is all white; The reverse side is a partially covered snow camouflage mesh, composed of white yellow spots in two colors. The white camouflage color has a reflection coefficient of ≥ 70% and a whiteness of ≥ 90 at 350 nm in the UV spectrum.
伪装网制造工艺
Manufacturing process of camouflage net
面料选择：采用高强涤纶长丝以井字平格织造方式由喷水织机进行织造，基布重量≤100 g/m2，坯布经过精练退浆处理，定形成品有效门幅150 mm，这样既能提高伪装网面料的拉伸及撕破强力，又能减轻伪装网的重量，便于架设使用和运输。
Fabric selection: High strength polyester filament is used to weave in a grid pattern using a water jet loom. The weight of the base fabric is ≤ 100 g/m2, and the grey fabric is subjected to scouring and desizing treatment. The effective width of the shaped product is 150 mm. This not only improves the tensile and tear strength of the camouflage net fabric, but also reduces the weight of the camouflage net, making it easy to install, use, and transport.
图案设计：面料开发时需注重斑块颜色与斑块面积的搭配比例，使斑块之间的过渡更加顺畅自然，图案斑点设计更趋科学，与自然光线投下的斑点深浅度吻合性更高，具有立体层次感，符合自然界的实际情况，从而使伪装特征更加显著。
Pattern design: When developing fabrics, attention should be paid to the matching ratio between patch color and patch area to make the transition between patches smoother and more natural. Pattern spot design is more scientific, and has a higher degree of consistency with the depth of spots cast by natural light. It has a three-dimensional sense of hierarchy, which is in line with the actual situation of the natural world, and thus makes the camouflage characteristics more prominent.
涂料选择：为保证涂料能够均匀地分散在浆料中，具有较好的稳定性，着色力强，遮盖力好，耐光性能优越。可选用品种多色谱广色泽鲜艳度和着色力高的有机涂料（白色涂料选择在紫外光谱内具备高反射率的无机材料）。
Coating selection: To ensure that the coating can be evenly dispersed in the slurry, with good stability, strong coloring power, good covering power, and superior light resistance. Multiple varieties of organic coatings with wide color spectrum, bright color, and high coloring power can be selected (for white coatings, inorganic materials with high reflectivity in the ultraviolet spectrum can be selected).
阻燃涂色整理：采用涂层的方法赋予面料耐久性阻燃性能，选择阻燃剂与涂层胶并按 8∶5 比例，辅以所需的有机无机颜料混合而成，然后在面料两面各刮涂一次，单面刮涂增重约20 ～ 25 g/m2，然后在160 ℃下烘40 s。这样能有效防止在后续印花过程中色浆渗化引起的正反两面颜色的相互影响，进而保证伪装网颜色的准确性。这种方法既可以达到面料阻燃的技术要求，同时面料两面也印上了底色，从而减少了印花的套色数。
Flame retardant coating and finishing: The method of coating is used to endow the fabric with durability and flame retardancy. An environmentally friendly flame retardant and coating adhesive are selected in a ratio of 8:5, supplemented by the required organic and inorganic pigments. Then, the fabric is scraped and coated once on both sides, with a weight increase of about 20-25 g/m2 on one side. Then, it is baked for 40 seconds at 160 ℃. This can effectively prevent the mutual influence of the front and back colors caused by color paste infiltration during the subsequent printing process, thereby ensuring the accuracy of the camouflage screen color. This method can not only meet the technical requirements of flame retardant fabric, but also print the base color on both sides of the fabric, thereby reducing the number of color sets in printing.
印花浆料选择：涂料对纤维没有亲和力，所以不能像染料一样通过与纤维的相互作用而上染，涂料与纤维的结合必须依赖于黏合剂膜的包覆及黏合剂大分子对纤维的黏附作用。 按底胶：面胶∶消光PU胶= 4∶3∶3 的比例混合，并加入2%的交联剂4%的钛白浆（提高涂料的遮盖力）1%的防霉剂，用增稠剂调合适黏度，搅拌均匀后，制成印花浆备用。将所需颜色的涂料色浆加入印花浆搅拌均匀后印花，烘干后印花表面无黏连现象，各种牢度均较好。
Selection of printing paste: Coatings have no affinity for fibers, so they cannot be dyed through the interaction with fibers like dyes. The binding between coatings and fibers must rely on the coating of adhesive films and the adhesion of adhesive macromolecules to fibers. Mix according to the ratio of base adhesive: surface adhesive: matte PU adhesive=4:3:3, and add 2% cross-linking agent 4% titanium white slurry (to improve the covering power of the coating) 1% mold inhibitor. Adjust to the appropriate viscosity with a thickener, stir evenly, and prepare printing paste for later use. Add the required color pigment paste to the printing paste and stir evenly before printing. After drying, there is no adhesion on the printing surface and all kinds of fastness are good.
确定面料及涂料浆料后，在经过阻燃涂色整理的面料上按色光要求进行印花打样配色，配色结束后，需要配制每种颜色生产所需的色浆，色浆配好后需要再次复小样确定每种颜色色光是否符合要求，只有符合色光要求后才能用于平网印花。
After determining the fabric and coating slurry, print and match according to the color requirements on the flame retardant coated fabric. After the color matching is completed, the necessary color paste for each color production needs to be prepared. After the color paste is prepared, it needs to be re sampled to determine whether each color meets the requirements. Only after meeting the color light requirements can it be used for flat screen printing.
