S2、成网：通过梳理机将准备的限位加工成薄网，成单向排列，进行加固，梳理机采用单锡林式，在锡林梳理机的离心力和气流的联合作用下，限位从锯齿上脱落，由气流均匀输送，凝聚在网帘上，形成纤网；
S3、纤网加固：通过射流喷网法来进行纤网加固使用，利用高压细束水流用在金属帘网的纤网上，使纤维受到间隙水力的作用向下运动，达到纤维间的缠结，使得纤网加固；
S4、干燥：通过干燥机，对加固后的纤网进行干燥，干燥温度控制在100℃-110℃，干燥后来进行对纤网进行喷涂粘合剂；
S5、喷涂：将粘合剂进行摇匀，通过喷涂机均匀地喷涂到纤网处；
S6、烘焙：将喷涂粘合剂后的纤网放置在烘焙箱内，并将温度控制在115℃-120℃，且控制纤网通过烘焙箱的速率在0.4m/s-0.6m/s；
S7、烘焙完成后，进行整理，轧光切割等步骤，来改善纤网的使用性能，提高美观性。
