Embodiment 1
[0061] refer to Figure 1-2 , a FDY paper tube with high-efficiency unwinding effect. The paper tube body is composed of a base tube layer and a parchment outer covering layer. One end of the paper tube body is a straight end, and the other end is a curled end. The inner diameter of the curled end is 116mm (inner roll length 3-4mm); the inner diameter of the straight side end is 114mm, and the inner diameter of the middle part of the paper tube is 114mm.
[0062] The production steps of the FDY paper tube are as follows:
[0063] (1) Preparation of base tube layer base paper:
[0064] The composition of the base paper is a mixture of 65% by weight of tube paper and 35% by weight of recycled paper, wherein the recycled paper consists of equal weight of waste paper tubes and waste and old corrugated paper with a weight of more than 120 grams per square meter, and the recycled paper contains Doped with 2% by weight ultrafine glass fibers, the fiber length is 10-20 μm, and the d...
Embodiment 2
[0079] An FDY paper tube, the paper tube body is composed of a base tube layer and a parchment outer covering layer, one end of the paper tube body is a straight end, the other end is a curled end, and the inner diameter of the curled end is 108mm; the inner diameter of the straight edge is 108mm , The inner diameter of the middle part of the paper tube is 108mm.
[0080] The production steps of the FDY paper tube are as follows:
[0081] (1) Preparation of base tube layer base paper:
[0082] The base paper is composed of 70% by weight bobbin paper and 30% by weight waste recycled paper bobbin paper, among which the recycled paper is doped with 3% by weight ultra-fine glass fiber, the fiber length is 10-20μm, and the diameter is 1-5μm .
[0083] First dry the recovered waste paper tubes and waste cardboard base paper and send them to the pulper for disintegration, add 10 times the weight of water, disintegrate for 20 minutes at a temperature of 55°C, and pass the coarse pul...
