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...

Abstract

The invention provides a fully drawn yarn (FDY) paper tube. A paper tube body comprises a paper tube base cylinder layer and an outer coating layer coating the external surface of the base cylinder layer. One end of the paper tube body is a straight edge end, and the other end of the paper tube body is a turned edge end. The base cylinder layer is formed by mixedly winding bobbin fiber paper and recycled base paper with a weight ratio of no less than 10%, the outer coating layer is made of facial tissues selected from parchments or glass paper, and the weight ratio of the recycled base paper is not less than 20%. The paper tube has good physical properties and mechanical properties and is simple and reasonable in structure. The end face friction of the paper tube can be effectively reduced, the retention rate of tail fibers is reduced, yarn breaking or fuzzy yarn during paper tube unwinding is avoided, and thus the unwinding success rate of a yarn cake is increased, and the graded product rate of chemical fiber products is promoted.

Description

technical field [0001] The invention relates to the technical field of paper tubes, in particular to an FDY paper tube with high-efficiency unwinding effect and paper tube performance applied in the field of chemical fiber spinning and a production method thereof. Background technique [0002] In the field of chemical fiber spinning industry, paper tubes are widely used as winding drums for spinning. In the process of high-speed spinning of polyester filaments, especially when unwinding FDY filaments, the ends of the original filaments are often broken due to the burrs on the end of the paper tube. In addition, the retention rate of the tails is high, resulting in a decline in the genuine rate of chemical fiber filaments. [0003] Fully drawn yarn (FDY) or high-speed spinning in the chemical fiber spinning industry has high requirements for paper tubes. The surface of ordinary paper tubes has defects such as small gaps and insufficient smoothness, which are difficult to meet...
