[0019] Figure: weft yarn 1, warp yarn 2. DETAILED DESCRIPTION

[0020] Embodiment

[0021] In combination Figure 1 , the embodiment provides a regenerated silk sandwich fabric, which is treated by an anti-wicking treatment process of a regenerated silk sandwich fabric. The anti-wicking treatment process of the regenerated silk sandwich fabric comprises the following method:

[0032] S5, anti-wicking treatment: dip the fabric into the anti-wicking treatment liquid, the roller linear pressure is 15N / mm, the drying temperature is 150℃, and the drying time is 1.2min; then roll up the fabric to make the anti-wicking regenerated filament mesh fabric, and the obtained product is marked as A1. Specific embodiment 2:

[0038] S5, anti-wicking treatment: the fabric is immersed in the anti-wicking treatment liquid, roller linear pressure 15 N / mm, drying temperature 150℃, drying time 1.2 minutes; then the fabric is rolled up to produce anti-wicking regenerated silk screen fabric, the product is marked as A2. Specific embodiment 3:

[0040] S1, selecting polyester regenerated silk 930dtex192f as warp yarn 2 and weft yarn 1;

[0041] S2, warping according to 12 ends / inch to produce warp yarn 2 beam;

[0044] S5, anti-wicking treatment: the fabric is immersed in the anti-wicking treatment liquid, roller linear pressure 15 N / mm, drying temperature 150℃, drying time 1.4 minutes; then the fabric is rolled up to produce anti-wicking regenerated silk screen fabric, the product is marked as A3.

[0045] Comparative example 1:

[0046] S1, selecting polyester regenerated silk 550dtex96f as warp yarn 2 and weft yarn 1;

[0047] S2, warping according to 18 ends / inch to produce warp yarn 2 beam;

[0050] Table 1 below is the anti-wicking performance comparison of the screen fabrics produced in the above examples A1, A2, A3, and comparative example B:

[0051]

[0052] Table 1

[0053] Note: The anti-wicking test is the 4-hour wicking height in mm.

[0054] As can be seen from Table 1, the anti-wicking regenerated silk made by the process of the application can reduce the height of the wicking of the sandwich fabric, reaching an industry level of ≤20 mm, and the height of wicking is related to the formula of the anti-wicking liquid.

[0055] The process scheme of the embodiment of the application first weaves the regenerated polyester silk into a sandwich fabric, and then performs anti-wicking treatment on the sandwich fabric, so as to form an anti-wicking protective film on the surface of the regenerated polyester silk fiber and improve the anti-wicking effect. Further, the anti-wicking treatment is performed by the formula of the anti-wicking treatment liquid of the embodiment of the application, and the sandwich fabric made of the anti-wicking regenerated silk is prepared, which has good environmental protection performance and is suitable for various types of sandwich fabrics, thereby widening the use range of the regenerated silk sandwich fabric, so that it can be used in high-end products, such as kayaks, building membrane structures, biogas pools, advertising cloth, light box cloth, inflatable castles, etc., so that the sandwich composite fabric is more environmentally friendly, reducing the consumption of petroleum resources and carbon emissions. On the other hand, fluorocarbon compounds are organic inert compounds, which have low viscosity and low surface tension, so the anti-wicking polyester silk formed by fluorocarbon compounds has poor adhesion when it is later adhered to PVC; in the application, since fluorocarbon compounds do not need to be added to the anti-wicking liquid to form a high anti-wicking effect, the regenerated silk has anti-wicking ability, and the adhesion is higher when it is later adhered to PVC.

[0056] It should be understood that: the above is only the preferred embodiment of the application, the protection scope of the application is not limited to the above-mentioned embodiments, and any technical solution falling within the scope of the application is within the protection scope of the application.

[0057] The above description of the drawings used in the embodiments only shows some embodiments of the application, and should not be considered as limiting the scope, and for those skilled in the art, other related drawings can be obtained without creative labor.
