Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment.

[0026] 1. Selection of raw materials

[0027] Raw material specifications: sulfonamide 2D×51mm; wool 70 S ; Flame-retardant viscose 2D × 51mm.

[0028] 2. Product design

[0029] According to the characteristics of polysulfone fiber, wool fiber and flame-retardant viscose fiber, the yarn fineness is designed to be 50Nm / 2, the blending ratio is 50% polysulfone fiber, 30% wool, and 20% flame-retardant viscose. It is 2 / 1 twill. In order to make the fabric feel smooth and waxy woolen fabric, considering the fabric style and tightness and other factors, the warp density of the fabric is 330 threads / 10cm, the weft density is 278 threads / 10cm, and the width is 155cm. Area density 260 g / m 2 .

[0030] 3. Process flow

[0031] (1) Spinning process flow

[0032] The semi-worsted process route is adopted, and the process flow is: wool → A186F carding machine → A272F drawing frame → A272...

Abstract

The invention provides polysulfonamide fiber / wool fiber / flame-retarding viscose blended fabric for electric welding protective clothing and a processing method thereof. Blended yarn is designed and developed according to a semi-fine-spinning route. The processing method comprises the steps of wool blending, cotton carding, drawing, roving, spinning, stranding, weaving, cleaning, drying, brushing, shearing, softening and decating. The linear density of the yarn is 50Nm / 2, theblending ratio among the polysulfonamide fiber / wool fiber / flame-retarding viscose is 50 / 30 / 20, and spinnability of the blended yarn is improved by means of high moisture absorption and good crimpiness of the wool fiber. 2 / 1 twill weave is adopted in the fabric, warp density of a finished product is 330 per 10cm, the weft density is 278 per 10cm, and the area density is 260g per square meters. Combustion performance of the final product can reach the level B of the welding clothing national standard, and the resistance to impact of molten metal, thermal stability and thermal protection can reach the level A of the welding clothing national standard. The blended fabric achieves a flame-retarding function, simultaneously has style characteristics of wool fabrics and comfort in wearing and is soft in touch.

Description

technical field [0001] The invention relates to an electric welding protective clothing fabric and a processing method thereof, in particular to a twill electric welding protective fabric processed by using 50Nm / 2 polysulfone fiber / wool fiber / flame-retardant viscose fiber blended yarn and a processing method thereof. Background technique [0002] Welding work is an indispensable and important process in modern industrial production and equipment maintenance, especially in many fields such as shipbuilding, container production, rolling stock, and pressure vessel production and maintenance. Welding work is the main type of work. Welding workers wear protective clothing when they work. Once they come into contact with flames or hot objects, they can effectively reduce the spread of flames on the clothing and avoid harm to the human body when metal droplets splash on the clothing. [0003] At present, although there are many varieties of welding protective clothing, pure cotton ...
