Embodiment 1

[0020] With 0.05mm stainless steel wire as the core material and flame-retardant vinylon as the covering fiber, the core-spun yarn with flame-retardant vinylon outside the stainless steel core is produced by a conventional core-spun yarn machine. Then interweave with the cotton-type flame-retardant vinylon fiber yarn with a conventional plain weave loom to form a canvas with a stainless steel core-spun yarn grid spacing of 1 mm. Use 2% (weight) emulsion of fluorine-containing acrylic ester to carry out double dipping and rolling, drying, and heat treatment to the canvas. The liquid rolling rate is 90%, the drying temperature is 90° C., and the heat treatment temperature is 140° C. for 4 minutes.

[0021] The test performance is as follows:

[0022] The washing resistance of fluoroacrylate coating is greater than 30 times;

[0023] Antistatic properties: volume resistance is less than 10 7 Ωcm

[0024] Electromagnetic shielding performance: Wrap the electromagnetic wave emis...

Embodiment 2

[0030] With 0.08mm stainless steel wire as the core material and vinyl chloride fiber as the covering fiber, a core-spun yarn with a stainless steel core and a vinyl chloride fiber outside the stainless steel core is manufactured with a conventional core-spun yarn machine. Then interweave with the yarn of cotton-type flame-retardant vinylon fiber with a conventional plain weave loom to form a canvas with a stainless steel core-spun yarn grid spacing of 2mm. Use 2% (weight) emulsion of fluorine-containing acrylic ester to carry out double dipping and rolling, drying, and heat treatment to the canvas. The liquid rolling rate is 90%, the drying temperature is 90° C., and the heat treatment temperature is 140° C. for 4 minutes.

[0031] The washing resistance of fluoroacrylate coating is greater than 30 times;

[0032] Antistatic properties: volume resistance is less than 10 7 Ωcm

[0033] Electromagnetic shielding performance: Wrap the electromagnetic wave emission source with ...

Embodiment 3

[0039] With 0.063mm stainless steel wire as the core material and flame-retardant vinylon as the covering fiber, a core-spun yarn with flame-retardant vinylon outside the stainless steel core is produced by a conventional core-spun yarn machine. Then interweave the yarn with cotton-type flame-retardant vinylon fiber with a conventional plain weave loom to form a canvas with a stainless steel core-spun yarn grid spacing of 0.5 mm. Use 2% (weight) emulsion of fluorine-containing acrylic ester to carry out double dipping and rolling, drying, and heat treatment to the canvas. The liquid rolling rate is 90%, the drying temperature is 90° C., and the heat treatment temperature is 140° C. for 4 minutes.

[0040] The washing resistance of fluoroacrylate coating is more than 30 times;

Abstract

This invention discloses a multi-permance sailcloth for tarpaulin and its manufacturing method, in which, the sailcloth is a basic cloth dipped by fluorine crylic acid ester and intertwoven with core-wrap yarn and flame resistant vinylon or chlorin-vinylon and the core of the core-wrap yarn is stainless steel wire, the preparation method includes: taking 0.05-0.08mm stainless steel wire as the core to be wrapped with chlorin vinylon or flaming resistant vinylon fibers to prepare core-wrapped yarn then interweaving them with vinylon to sailcloth then to be dipped and rolled two times, dried and heated to get the multi-performance sailcloth, which only absorbs but not reflects electromagnetic waves so as to play the role of anti-static and electromagnetic shield.

Description

technical field [0001] The invention relates to a multifunctional tarpaulin canvas and a manufacturing method thereof. Background technique [0002] With the development of science and technology, the use of tarpaulins in industrial textiles is increasing, especially for goods transported by railways, ships, and automobiles, and materials stored in ports, docks, warehouses, etc. are inseparable from tarpaulins. According to statistics, my country's annual use of tarpaulins is more than 25 million square meters, and its fiber consumption reaches 13,000 tons. If cotton yarn is used, it is equivalent to the total annual production of lint on 400,000 mu of land. It can be seen that tarpaulins occupy an important role in industrial textiles. proportion. [0003] The fabrics used to produce tarpaulins mainly include pure natural fiber fabrics, synthetic fiber fabrics and blended fabrics. The tarpaulin fabrics currently produced in our country are mainly pure cotton and vinylon fa...
