Problems solved by technology

At present, flame-retardant cotton fabrics or aluminum-coated fabrics are generally used, but they have poor resistance to molten metal impact and poor wearing comfort.
At present, the molten metal splash fabrics mainly made of wool / viscose on the market have a dimensional stability of more than 5%, which makes them feel itchy and poor in comfort.

Embodiment 1

[0038] A protective fabric containing flame-retardant polyester molten metal splashes, which is made of blended flame-retardant viscose fiber and flame-retardant polyester fiber, of which flame-retardant viscose fiber accounts for 70%, and flame-retardant polyester fiber accounts for 30%. The mass is 400g / m 2 .

[0039] The dyeing and finishing process adopted for the above flame-retardant polyester molten metal splash protection fabric:

[0040] Step 1, singeing the flame-retardant polyester molten metal splash protection fabric;

[0041] Step 2, enzymatic deboiling

[0042] Perform enzymatic deboiling treatment on the fabric treated in step 1. The deboiling solution is composed of compound desizing enzyme TF-162 with a concentration of 20g / L. Padding in the cooking liquid, using two dipping and two rolling, the excess rate is 70% to 100%; then steam the molten metal splash protection fabric after padding, the steaming temperature is 100°C to 102°C, and the time is 40min ...

Embodiment 2

[0052] In this embodiment, a protective fabric containing flame-retardant polyester molten metal splashes is formed by blending flame-retardant viscose fiber and flame-retardant polyester fiber, wherein flame-retardant viscose fiber accounts for 80%, and flame-retardant polyester fiber accounts for 20%. The mass per unit area of ​​the fabric is 350g / m 2 .

[0053] The dyeing and finishing process adopted for the above flame-retardant polyester molten metal splash protection fabric:

Abstract

The invention discloses a molten metal spatter fabric containing flame-retardant polyester. The molten metal spatter fabric is composed of the following components in percentages by mass: 70%-90% of flame-retardant viscose fiber and 10%-30% flame-retardant polyester fiber, and the sum of the mass percent of the components is 100%. The molten metal spatter fabric containing the flame-retardant polyester has good resistance to molten metal impact, good flame-retardant performance and good wearing comfort. The invention further discloses a dyeing and finishing process of the molten metal spatterfabric containing the flame-retardant polyester.

Description

technical field [0001] The invention belongs to the technical field of molten splash safety protection fabrics, and relates to a flame-retardant polyester molten metal splash fabric, and also relates to a dyeing and finishing process for the flame-retardant polyester molten metal splash fabric. Background technique [0002] The process of smelting production is relatively complicated, and there are many hazards in the whole production process, including smoke, noise, high temperature radiation, splashing of molten metal and slag, explosion, blast furnace gas, blast furnace gas combustion explosion, coal powder explosion, etc. According to the statistics of accident data over the years, among them, the burning accidents are the most, and the specific manifestations are burns to the human body such as the overturning and falling of high-temperature metal liquid, the radiant heat of high-temperature metal liquid, the splashing and leakage of molten metal, etc.; and the main caus...
