Embodiment 1

[0030] A production process of anti-wrinkle hot water bag leather, comprising the following steps:

[0031] (a) The base fabric is opened and shaped, and the base fabric is twill satin; the coiling tension of the base fabric is set at 1.125N to keep the base fabric loose and prevent wrinkling; the temperature is 180°C, and the speed is 7m / min; The track of the cloth opening and shaping oven adopts a parallel type, which reduces the tension of the cloth and reduces the deformation of the cloth;

[0032] (b) Paste on the base cloth, the temperature is 180°C, and the speed is 7m / min; the paste is a PU two-component paste, and it is evenly pasted on the base cloth for 2 times, and the amount of paste is 40g / m.2 times;

[0033] (c) Preparing PVC leather, laminating it with the base fabric, and adopting calendering, including (1) internal mixing, (2) open refining, (3) extrusion, (4) calendering and (5) foam embossing; PVC leather The ratio of raw materials by weight is: 45 parts o...

Embodiment 2

[0036] A production process of anti-wrinkle hot water bag leather, comprising the following steps:

[0037] (a) The base fabric is opened and shaped, and the base fabric is a long-pile fabric; the winding tension of the base fabric is 1.125N to keep the base fabric loose and prevent wrinkling; the temperature is 175°C, and the speed is 5m / min; The track of the shaping oven adopts a parallel type, which reduces the tension of the cloth and reduces the deformation of the cloth;

[0038] (b) Paste on the base cloth, the temperature is 175°C, and the speed is 5m / min; the paste is a PU two-component paste, which is evenly pasted on the base cloth twice, and the amount of paste is 35g / m.2 times;

[0039] (c) Preparing PVC leather, laminating it with the base fabric, and adopting calendering, including (1) internal mixing, (2) open refining, (3) extrusion, (4) calendering and (5) foam embossing; PVC leather The ratio of raw materials by weight is: 45 parts of PVC resin, 30.6 parts o...

Embodiment 3

[0042] A production process of anti-wrinkle hot water bag leather, comprising the following steps:

[0043] (a) The base fabric is opened and shaped, and the base fabric is short flannelette; the winding tension of the base fabric is 1.125N to keep the base fabric loose and prevent wrinkling; the temperature is 185°C, and the speed is 9m / min; The track of the shaping oven adopts a parallel type, which reduces the tension of the cloth and reduces the deformation of the cloth;

[0044] (b) Paste on the base cloth, the temperature is 185°C, and the speed is 9m / min; the paste is a PU two-component paste, and it is evenly pasted on the base cloth for 2 times, and the amount of paste is 45g / m.2 times;

Abstract

The invention discloses a production process of anti-wrinkle hot water bag leather, which belongs to the technical field of PVC leather processing. It includes four steps (a) base cloth opening and shaping; (b) paste on the base cloth; (c) preparation of PVC leather and lamination with the base cloth; (d) cooling and coiling; Excessive stretching, and ensure the appropriate temperature and paste amount, so that after the hot water bag leather is made into a hot water bag, there will be no wrinkling, edge warping, delamination and other phenomena.

Description

technical field [0001] The invention relates to a production process, in particular to a production process of anti-wrinkle hot water bag leather, belonging to the technical field of PVC leather processing. Background technique [0002] In the cold weather in winter, many people will feel unwell. At this time, the function of the hot water bag is highlighted. The hot water bag can not only warm the human body, but also promote wound healing, relieve pain, compress the back to relieve cough and hypnosis. [0003] The electric hot water bag uses PVC leather as the hot water bag body, but after the current hot water bag is used for a period of time, the surface of the hot water bag will have wrinkles, warping and delamination, which will affect the appearance and use effect. Contents of the invention [0004] The object of the present invention is to provide a hot water bottle leather production process to prevent the hot water bottle leather from wrinkling, edge warping and...
