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 with vinyl chloride copolymer, which has high compatibility with PVC resin, which solves the migration problem of plasticizer in low temperature environment or during long-term use, thus ensuring the 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 are put into a reaction kettle, the temperature is controlled at 45-60° C., and stirred for 4-6 hours to obtain the required vinyl chloride copolymer.

[0059] The beneficial effect of adopting the technical solution of this embodiment will be further described below through several groups of examples and comparati...

Embodiment 1

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

[0062] Step 1: Opening, mixing, and combing 40wt% polyester fiber with a specification of 3D*51mm and 60wt% polyester fiber with a specification of 1.5D*51mm to form a fiber web layer;

[0063] Step 2, transporting the fiber mesh layer to the middle of the two layers of woven cloth layers arranged up and down, and stitching and compounding the carbon fiber filaments to obtain the base cloth layer;

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

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

Embodiment 2

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

[0069] Step 1: Opening, mixing, and combing 30wt% polyester fiber with a specification of 3D*51mm and 70wt% polyester fiber with a specification of 1.5D*51mm to form a fiber web;

[0070] Step 2, transporting the fiber mesh layer to the middle of the two layers of woven cloth layers arranged up and down, and stitching and compounding the carbon fiber filaments to obtain the base cloth layer;

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

[0072] Wherein, the weft yarn of the woven fabric layer in step 2 is a core-spun yarn blended with carbon fiber as the skin and nylon filament as the core, and the use ratio of carbon fiber yarn and nylon fiber yarn is 1:3, and the mixing weight percentage It is 30%: 70%, the fineness of carbon fiber is 2.5D, and the length is 51mm; the fineness of nylon fiber is 1.5D, ...

Abstract

The invention discloses low-temperature-resistant PVC covering cloth and a production method thereof, and belongs to the field of spinning. The low-temperature-resistant PVC covering cloth comprises a base cloth layer and PVC coatings coated on the upper side surface and the lower side surface of the base cloth layer, wherein the base cloth layer is formed by stitching an upper woven cloth layer and a lower woven cloth layer through carbon fiber filaments. The covering cloth has the advantages that the base cloth layer is formed by sewing and weaving the woven cloth through the carbon fiber filaments, the overall size stability of the covering cloth is improved due to the fact that the woven cloth is excellent in strength and shape maintaining effect, and the carbon fiber filaments are matched with the woven cloth to exactly make up for the defect of the warp-wise strength of the woven cloth, so that strength and the size stability of the covering cloth are not greatly influenced in the low-temperature severe environment, and the covering cloth is particularly suitable for being used in the northern severe environment such as the strong wind or sand storm environment and has the advantages of being high in strength, good in size stability, long in service life and the like.

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 major product in industrial textiles, tarpaulin serves various related fields of society. It can be used to block ultraviolet radiation, prevent cold, waterproof, and anti-aging. It is an excellent product for protecting against harsh environmental influences. Among them Compared with ordinary PE tarpaulins, PVC tarpaulins are far superior to PP and PE tarpaulins in rain resistance, 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. The raw material formula of its PVC coating includes the following components in parts by weight: 80 parts of PVC paste resin, 70-90 parts of dioctyl phthalat...
