Embodiment 1

[0056] This embodiment discloses a coating process for Oxford cloth unglue coated fabrics, comprising the following steps:

[0057] S1: Lay Oxford cloth flat, fix the four corners, and clean with hot air;

[0058]S2: Use the nozzle to spray the tackifier on the surface of the Oxford cloth in a spiral shape from the inside to the outside. At the same time, use the inclined scraper to scrape off the tackifier following the rotation of the nozzle. The rotation speed is 2-5r / s, and the thickness of the tackifier is 0.1mm~0.5mm;

[0059] S3: Melt the glue, use the nozzle to spray the glue on the surface of the Oxford cloth in a spiral shape from the inside to the outside, and use a beveled scraper to scrape the glue with the rotation speed of 4~7r / s, following the rotation of the nozzle. The temperature of the unglue is kept at 180-190°C, and the thickness of the unglue is 0.3-1mm;

[0060] S4: After scraping, let it stand for 2-3 hours, and wait for the glue to dry;

[0061] S5...

Embodiment 2

[0067] This embodiment discloses a coating process for Oxford cloth unglue coated fabrics, comprising the following steps:

[0069] S2: Use the nozzle to spray the tackifier on the surface of the Oxford cloth in a spiral shape from the inside to the outside. At the same time, use the inclined scraper to scrape off the tackifier following the rotation of the nozzle. The rotation speed is 2-5r / s, and the thickness of the tackifier is 0.3mm;

[0070] S3: Melt the glue, use the nozzle to spray the glue on the surface of the Oxford cloth in a spiral shape from the inside to the outside, and use a beveled scraper to scrape the glue with the rotation speed of 4~7r / s, following the rotation of the nozzle. The temperature of the unglue is kept at 180-190°C, and the thickness of the unglue is 0.7mm;

[0071] S4: After scraping, let it stand for 2-3 hours, and wait for the glue to dry;

[0072] S5: Turn ...

Embodiment 3

[0078] This embodiment discloses a coating process for Oxford cloth unglue coated fabrics, comprising the following steps:

[0079] S1: Lay Oxford cloth flat, fix the four corners, and clean with hot air;

[0080] S2: Use the nozzle to spray the tackifier on the surface of the Oxford cloth in a spiral shape from the inside to the outside, and at the same time use a beveled scraper to scrape off the tackifier following the rotation of the nozzle, the rotation speed is 3.5r / s, and the thickness of the tackifier is 0.1 mm~0.5mm;

[0081] S3: Melt the glue, spray the glue on the surface of the Oxford cloth in a spiral shape from the inside to the outside with the nozzle, and use the inclined scraper to scrape the glue with the rotation speed of 5.5r / s. The temperature of the glue is kept at 185°C, and the thickness of the glue is 0.3-1mm;

[0082] S4: After smoothing, let it stand for 2.5H, and wait for the Uliglue to dry;

[0083] S5: Turn the Oxford cloth over so that the sid...

Abstract

The invention discloses a coating process of an Oxford fabric polyurethane coating fabric. The method includes the steps: S1 flatly laying an Oxford fabric, and leaning the Oxford fabric by hot air; S2 spirally spraying tackifiers onto the surface of the Oxford fabric by a sprayer from inside to outside, and enabling an oblique plane scraper to rotate along with the sprayer to flat the tackifiersin a scraped manner; S3 melting polyurethane, spirally spraying the melted polyurethane onto the surface of the Oxford fabric by the sprayer from inside to outside, and enabling the oblique plane scraper to rotate along with the sprayer to scrape the polyurethane; S4 performing standing, drying and solidifying after the polyurethane is scraped; S5 turning over the Oxford fabric, and repeating thesteps S2 to S4; S6 erecting the Oxford fabric; S7 heating the edge of the Oxford fabric, spraying the polyurethane, and scraping the polyurethane; S8 rotating the Oxford fabric, repeating the step S7,enabling the edge of the Oxford fabric to be uniformly sprayed by the polyurethane; S9 performing standing, drying and solidifying. The method is simple in process, the coated surface is smooth, combination is firm, waterproof effects and surface elasticity are good, and shapes are stable.

Description

technical field [0001] The invention relates to a coating process, in particular to a coating process of an Oxford cloth unglue-coated fabric. Background technique [0002] Oxford cloth is thin and soft to the touch, but it cannot form a good fixed shape, and the fabric is not elastic and waterproof enough. When it is made into a bag, it needs to use more supporting structures and add an additional waterproof layer, the process is complicated, the cost is high, and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coating process of Oxford cloth unglue coated fabric, which has a simple process, smooth surface after coating, firm bonding, good waterproof effect and surface elasticity, and stable shape. [0004] In order to solve the above-mentioned technical problems, the invention provides a kind of coating process of Oxford cloth unglue coated fabric, comprising the following steps: [0...
