Embodiment 1

[0009] Embodiment 1, the production method of environment-friendly high-temperature-resistant regenerated cellulose laminated spandex tube, firstly, the bobbin paper is divided into four kinds of paper tapes with different widths, which are 107.8mm, 107.9mm, 108mm, and 108.1mm respectively, Two layers of these four kinds of paper tapes are coated with glue, and then wound into a bobbin from the inside to the outside at the same time, and then the regenerated cellulose film is wound on the outside of the bobbin to make a semi-finished product. After drying, static balance, Weighing, bobbin cutting, finishing, inspection, and packaging steps to get the finished product. At the same time as winding, glue is coated on the inner surface of the regenerated cellulose laminated film, and 30°C is added dropwise on the outer surface of the regenerated cellulose laminated film. water.

Embodiment 2

[0010] Embodiment 2, the production method of the environment-friendly high temperature resistant regenerated cellulose laminated spandex tube, firstly, the bobbin paper is divided into four kinds of paper tapes with different widths, respectively 107.85mm, 107.95mm, 108.05mm, 108.15mm, , each of these four kinds of paper tapes takes 4 layers to coat glue, and then winds them into a bobbin from the inside to the outside at the same time, and then wraps the regenerated cellulose film on the outside of the bobbin to make a semi-finished product, which is dried and left to balance , weighing, bobbin cutting, finishing, inspection, and packaging steps to obtain the finished product. At the same time as winding, glue is applied to the inner surface of the regenerated cellulose laminated film, and 40°C is dripped on the outer surface of the regenerated cellulose laminated film. of water.

Embodiment 3

[0011] Embodiment 3, the production method of environment-friendly high-temperature-resistant regenerated cellulose laminated spandex tube, firstly, the bobbin paper is divided into four kinds of paper tapes with different widths, which are respectively 107.75mm, 107.85mm, 107.95mm, and 108.05mm. , each of these four kinds of paper tapes takes 5 layers to apply glue, and then winds them into bobbins from the inside to the outside at the same time, and then wraps the regenerated cellulose film on the outside of the bobbins to make a semi-finished product, which is dried and left to balance , weighing, bobbin cutting, finishing, inspection, and packaging steps to obtain the finished product. At the same time as winding, glue is applied to the inner surface of the regenerated cellulose laminated film, and 50°C is dripped on the outer surface of the regenerated cellulose laminated film. of water.

Abstract

The invention relates to a method for producing an environment-friendly type regenerated cellulose film-pressed polyurethane pipe with high-temperature resistance, which comprises the following steps of: splitting cop pipe paper into paper tapes according to requirements, soaking the paper tapes into glue for coating, coiling the paper tapes into a bobbin pipe simultaneously after coating completely, and then winding a regenerated-cellulose pressed film outside the bobbin pipe to manufacture a semi-finished product so as to obtain a finished product by the steps of drying, standing balance, weighing, bobbin pipe slitting, finishing, checking and packaging. The method for producing the environment-friendly type regenerated cellulose film-pressed polyurethane pipe with the high-temperature resistance is characterized in that the cop pipe paper is split into four paper tapes with different breadths, the paper tapes are respectively 107.8+ / -0.05mm, 107.9+ / -0.05mm, 108+ / -0.05mm and 108.1+ / -0.05mm, 2 to 5 layers are respectively taken from the four paper tapes for coating with the glue, and then the paper tapes are sequentially coiled into the bobbin pipe from the inside to the outside simultaneously. The method for producing the environment-friendly type regenerated cellulose film-pressed polyurethane pipe with the high-temperature resistance has the following advantages that the strength and the smoothness of the product are effectively enhanced, the capabilities of pressure resistance, moisture prevention, spinning formation and the like are reinforced, and the capability of steaming / cooking resistance is also enhanced.

Description

technical field [0001] The invention relates to a production method of a spandex tube, in particular to a production method of a degradable environment-friendly high temperature resistant regenerated cellulose laminated spandex tube. Background technique [0002] Spandex tubes used in the chemical fiber textile industry generally require high temperature steam resistance and strong compressive strength, so the production requirements for spandex tubes are also extremely stringent. During the production process of the current spandex tube, there will be seams between the inner paper tape and the outer paper tape, which will affect the appearance and strength of the paper tube. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide a production method of an environment-friendly high temperature resistant regenerated cellulose laminated spandex tube with high co...
