Method for producing environment-friendly type regenerated cellulose film-pressed polyurethane pipe with high-temperature resistance

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
