Embodiment 1
[0072] Prepare 106 g / m2 by mixing polyester staple fibers 31 with a denier of 4.4 dtex, a length of 76 mm, and a weight ratio of 70 wt % with a denier of 5 dtex, a length of 60 mm, and a weight ratio of 30 wt % of glass staple fibers 32 Bottom 1. Mixing is achieved through a filling, balancing and carding-opening system capable of achieving high mixing uniformity.
[0073] The fibers were pneumatically conveyed at 90 m / min to the volume feed system of the longitudinal drum card which produced two separate films each weighing 40 g / m2 which were deposited on two conveyors.
[0074] Between the two films, a glass scrim 4 is inserted with a rectangular grid of 68tex yarns 1.6x0.8 threads / cm, using a water jet needling machine consisting of four hydroentangling units at a pressure of 150 bar Reinforces the composite formed by the two films and the intervening scrim.
[0075] The base layer 1 was dried and heat-set by hot air calender at 230° C., using a 50% styrene-butadiene bind...
Embodiment 2
[0085] The bottom layer 1 of 85g / m is prepared by mixing polyester staple fibers 31 with a denier of 4.4dtex, a length of 76mm, and 70wt% with a denier of 5dtex, a length of 60mm, and a weight ratio of 30wt% of short glass fibers 32. Mixing is achieved through a filling, balancing and carding-opening system capable of achieving high mixing uniformity.
[0086] The fibers were pneumatically conveyed at 90 m / min to the volume feed system of the longitudinal drum card which produced two separate films of 30 g / m2 each, which were deposited on two conveyors.
[0087] Between the two membranes, glass scrim 4 is inserted with a rectangular grid of 34tex yarns 1.6x0.8 threads / cm, utilizing four hydroentanglement units operated by a wetting unit and at a pressure of 50-150 bar The formed water-jet needleloom consolidates the composite formed by the two films and the intervening scrim.
[0088] The base layer 1 was dried and heat-set by hot air calender at 230° C., using a 50% styrene-...
Embodiment 3
[0098] The bottom layer 1 of 140g / m is prepared by mixing polyester staple fibers 31 with a denier of 4.4dtex, a length of 76mm, and 70wt% with a denier of 5dtex, a length of 60mm, and a weight ratio of 30wt% of short glass fibers 32. Mixing is achieved through a filling, balancing and carding-opening system capable of achieving high mixing uniformity.
[0099] The fibers 3 are pneumatically conveyed at 90 m / min to the volume feed system of the longitudinal drum card, which produces two separate films of 50 g / m2 each, which are deposited on two conveyors.
[0100] Between the two films, a glass scrim 4 is inserted with a rectangular grid 2x2 threads / cm of 68tex yarns, with a jet consisting of a wetting unit and four hydroentangling units operating at a pressure of 50-150 bar. The hydroneedling machine consolidates the composite formed by the two films and the intervening scrim.
[0101]The bottom layer 1 was dried and heat-set at 230°C by a hot air calender, and a resin mixtu...
