Problems solved by technology

The production method of the double-sided pattern flag is mostly made by the discharge printing process. The discharge printing process requires plate making, and it is difficult to control the fabric process of super large format, complex colors and bright colors.
Currently, the printing technology does not carry out waterproof treatment, which makes the flag easy to get wet and dirty in the case of rain or water splashing; in the case of strong wind or special need to blow the flag at a high speed, the existing flag fabric shakes violently, is seriously damaged, and is very It is difficult to maintain the original shape, so it is necessary to improve the strength, tear resistance, waterproof and antifouling performance of the flag fabric
Usually the flag is a means of publicity, so it needs to have good color and printed patterns on both sides. The existing technology cannot achieve the effect of only printing on one side and printing on both sides.

Embodiment 1

[0040] In this embodiment, a huge red flag fabric is produced, and the specific production method is as follows:

[0041] 1) Gray cloth pretreatment:

[0042] Using high-strength nylon 66 fiber filaments as raw materials, weaving with double-line grid plain weave to make nylon 66 gray cloth, and then performing conventional whitening and drying to obtain nylon whitening cloth;

[0043] 2) Coating treatment:

[0044] First, the formula components are mixed and stirred in proportion to obtain a waterproof coating. The raw materials of the waterproof coating are: 34% of solvent-based resin silicone oil, 26% of toluene, 0.8% of curing agent, 3.5% of silane coupling agent, 1.5% of catalyst and the rest amount of diluent; then on the gray cloth obtained in step 1), coat the prepared waterproof paint, and be coated on one side, then dry and set the shape, that is, form a waterproof coating on the surface of the white cloth; After that, it needs to be used within 24 hours;

[0045]...

Embodiment 2

[0051] The present embodiment makes a kind of waterproof and anti-airflow impact flag fabric, and the specific manufacturing method is the same as in embodiment 1, except that the high-strength nylon 66 fiber filament in the present embodiment has a grammage of 39g / m. 2 Nylon 66 practiced white check silk with a fineness of 30D; the grid size is 3 × 5mm; the raw material of the waterproof coating consists of: solvent-based resin silicone oil 32%, toluene 27%, curing agent 0.8%, silane coupling agent 4%, catalyst 1.2% and the rest of diluent; the thermal transfer temperature is 223°C, and the thermal transfer speed is 5.6m / min.

[0052] The waterproof and anti-airflow impact flag fabric prepared in this embodiment is designated as fabric A. The mechanical, waterproof, color fastness and other performance indicators of the fabric A were tested, and the results were: (1) tear strength: 142N in the warp direction and 139N in the weft direction; (2) the color fastness to rubbing wa...

Embodiment 3

[0058] This embodiment makes a kind of waterproof and anti-airflow impact flag fabric, the specific manufacturing method is the same as that of embodiment 1, the difference is that nylon 6 fiber filament is used as raw material in this embodiment, and the square meter weight is 73g / m 2 , the fineness is 70D, and the grid size is 2×2mm.

[0059] Performance indicators such as mechanics, waterproof, and color fastness of the waterproof and airflow-resistant flag fabric prepared in this embodiment are tested, and the results are: (1) tearing strength: 213N in warp direction and 204N in weft direction; (2) rubbing color The fastness is grade 4-5; (3) the color difference between the front and the back is grade 4; (4) the degree of water staining is grade 4; (5) the color fastness to light is grade 4. The tearing strength of the fabric has been significantly improved compared with the tearing strength of the nylon white cloth of the present embodiment (tearing strength: 114N in the...

Abstract

The invention relates to a waterproofing and air impacting resisting flag fabric and a manufacturing method thereof. The waterproofing and air impacting resisting flag fabric is characterized in that high-strength nylon 66 is used as a base material, and a waterproofing coating is arranged on the high-strength nylon 66, wherein a waterproofing paint of the waterproofing coating comprises the following raw materials: 30-35% of solvent type resin silicone oil, 25-30% of methylbenzene, 0.5-1% of a curing agent, 3-5% of a silane coupling agent, 1-3% of a catalyst, and the balance of a thinner; and a pattern is printed on the coated high-strength nylon 66. The fabric is good in waterproofing effect, and high in air impacting resistance; the printing color is uniform; the pattern is clear; the color fastness is high; and the effect of printing one surface to realize a two surface printing effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of flag fabric production, in particular to a waterproof and airflow-resistant flag fabric and a production method thereof. The flag produced by the method can achieve waterproof, anti-airflow impact and single-sided printing with double-sided effect. Background technique [0002] In the military parade commemorating the 70th anniversary of the victory of the Anti-Japanese War on September 3, 2015, the size of the national flag and military flag hoisted by the helicopter were 6m×9m and 6m×7.5m respectively, and the flying speed was 160-180 km / h. It used to be a big problem in the preparations for the military parade to prevent the national flag and military flag from swinging at will, stretching straight and square, and flying at high speed without any damage. During high-speed flight, the red flag hanging on the helicopter cable will be impacted by a huge airflow, especially at the tail of the red flag wil...
