Embodiment approach

[0055] As a preferred embodiment, the preparation of the PVC coating 3 includes the following raw materials in parts by weight:

[0056]

[0057] PVC coating 3 is plasticized by vinyl chloride copolymer, which has high compatibility with PVC resin, which solves the problem of plasticizer migration in low temperature environment or during long-term use, thus ensuring PVC coating 3 and the stability of the tarpaulin in harsh environments.

[0058] As a preferred embodiment, the preparation process of the vinyl chloride copolymer is as follows: 70-90wt% vinyl chloride, 10-30wt% butyl linoleate, 0.3-1wt% sodium lauryl sulfate and 0.3-1 wt% potassium persulfate into a reaction kettle, the temperature is controlled to be 45-60 DEG C, and the mixture is stirred for 4-6 hours to obtain the desired vinyl chloride copolymer.

[0059] The beneficial effects of the technical solutions of this embodiment are further described below through several groups of examples and comparative exa...

Embodiment 1

[0061] The production method of PVC canopy in the present embodiment, the concrete steps are as follows:

[0062] Step 1: 40wt% polyester fibers with a size of 3D*51mm and 60wt% polyester fibers with a size of 1.5D*51mm are opened, mixed and combed into a web to obtain a fiber web layer;

[0063] In step 2, the fiber mesh layer is transported to the middle of the two woven fabric layers arranged up and down, and the carbon fiber filaments are stitched and compounded to obtain a base fabric layer;

[0064] Step 3: Coating PVC coating on the upper and lower sides of the base fabric layer to obtain a PVC tarpaulin.

[0065] Wherein, in step 2, the weft yarn of the woven fabric layer is a core-spun yarn that is blended with carbon fiber as the skin and nylon filament as the core, and the use ratio of the carbon fiber yarn and the nylon fiber yarn is 1:1, and the mixed weight percentage It is 40%: 60%, the fineness of carbon fiber is 4D and the length is 51mm; the fineness of nylo...

Embodiment 2

[0068] The production method of PVC canopy in the present embodiment, the concrete steps are as follows:

[0069] Step 1: 30wt% polyester fibers with a specification of 3D*51mm and 70wt% polyester fibers with a specification of 1.5D*51mm are opened, mixed and combed into a web to obtain a fiber web layer;

[0070] In step 2, the fiber mesh layer is transported to the middle of the two woven fabric layers arranged up and down, and the carbon fiber filaments are stitched and compounded to obtain a base fabric layer;

[0071] Step 3: Coating PVC coating on the upper and lower sides of the base fabric layer to obtain a PVC tarpaulin.

[0072] Wherein, in step 2, the weft yarn of the woven fabric layer is a core-spun yarn that is blended with carbon fiber as the skin and nylon filament as the core, and the use ratio of the carbon fiber yarn and the nylon fiber yarn is 1:3, and the mixed weight percentage It is 30%: 70%, the fineness of carbon fiber is 2.5D and the length is 51mm; ...

Abstract

The invention discloses a low-temperature-resistant PVC tarpaulin and a production method thereof, belonging to the field of textiles, comprising a base fabric layer and a PVC coating attached to the upper and lower sides of the base fabric layer, and the base fabric layer consists of upper and lower two sides. Layers of woven fabric stitched with carbon fiber filaments. The beneficial effects of the present invention are: the base fabric layer is made of woven fabric through carbon fiber filament sewing, and the dimensional stability of the whole tarpaulin is improved due to the excellent strength and shape retention effect of the woven fabric itself, while the carbon fiber The combination of filament stitching and woven fabric just makes up for the lack of warp strength of woven fabric, so that the strength and dimensional stability of the tarpaulin will not be greatly affected in low temperature and harsh environments, especially suitable for northern Used in harsh environments such as strong winds or sandstorms, it has the advantages of high strength, good dimensional stability, and long service life.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a low temperature-resistant PVC tarpaulin and a production method thereof. Background technique [0002] As a traditional large-scale product in industrial textiles, tarpaulins serve various related fields of society. They can be used to block ultraviolet radiation, prevent cold, waterproof, and anti-aging. It is an excellent product for protecting against harsh environments. Among them Compared with ordinary PE tarpaulins, PVC tarpaulins are much more rainproof than PP and PE tarpaulins, and are widely used in tents, automobiles, trains, storage and other fields. For example, Chinese patent CN105690953A discloses a folding-resistant PVC tarpaulin, which is composed of mesh cloth coated with PVC coating on both sides, and the raw material formula of the PVC coating includes the following components according to parts by weight: 80 parts of PVC paste resin, 70-90 parts of dioctyl phthalat...
