Problems solved by technology

[0005] The preparation method of this kind of flame-retardant clothing is usually carried out independently by different manufacturers in the links of raw material supply, cloth processing and clothing production. On the other hand, because most of the flame-retardant fibers used are nylon, the flame-retardant fabrics produced are generally thin, and under the radiant heat of molten steel, they will still burn in large areas, and the flame-retardant and heat-insulating properties are not good.

Embodiment 1

[0027] Follow the steps below to make flame retardant clothing:

[0028] (1) Measure the shrinkage ratio of cotton cloth: wash the cotton cloth with length A and width B in water, add desizing agent to the water, the proportion of cotton cloth, desizing agent and water is 8:1.2:200, The water temperature is 70°C, and the washing time is 20 minutes; then the washed cotton cloth is dried, and then dried at a temperature of 110°C, and the length X and width Y of the dried cotton cloth are measured, and the shrinkage ratio in the length direction is calculated K1=X / A, width shrinkage ratio K2=Y / B;

[0029] (2) Garment making: the dimension of the prefabricated garment is L in the length direction and H in the width direction, and the cotton cloth is cut according to the dimensions calculated by L / K1 and H / K2, and then sewn into clothes;

[0030] (3) Desizing and drying: Add clothes and desizing agent to water at a temperature of 70°C. The proportion of clothes, desizing agent and...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 lies in the following steps:

[0036] (1) In the step of measuring the shrinkage ratio of cotton cloth: the proportion of cotton cloth, desizing agent and water is 9:1.2:200 in sequence, the water temperature is 80°C, and the washing time is 25min; then dry at a temperature of 125°C;

[0037] (3) In the steps of desizing and drying: the proportion of clothes, desizing agent and water is 9:1.2:200 in turn; add clothes and desizing agent to water at a temperature of 80°C, wash for 25 minutes, remove the clothes and shake Dry, and then dry, the drying temperature is 125 ℃;

[0038] (4) In the step of soaking the flame retardant: add the flame retardant to water at a temperature of 100°C to make a solution. carry out secondary drying;

[0039] (5) In the step of ironing and shaping: the baking temperature is 190° C., the baking time is 15 minutes, and then cooled at room temperature for 25 minutes to obtain a flame-r...

Embodiment 3

[0041] The difference between this embodiment and Embodiment 1 lies in the following steps:

[0042] (1) In the step of measuring the shrinkage ratio of cotton cloth: the proportion of cotton cloth, desizing agent and water is 10:1.2:200 in sequence; the water temperature is 65°C, and the washing time is 15min; then dry at a temperature of 105°C;

[0043] (3) In the desizing and drying steps: add clothes and desizing agent to water at a temperature of 65°C, the proportion of clothes, desizing agent and water is 10:1.2:200 in turn; take out the clothes after washing for 15 minutes and shake them off Dry, then dry, the drying temperature is 105 ℃;

[0044] (4) In the step of soaking the flame retardant: add the flame retardant to water at a temperature of 85°C to make a solution, the proportion of the flame retardant to water is 1:8; soak it for 35 minutes, remove it, and then soak it at a temperature of 105°C carry out secondary drying;

[0045] (5) In the step of ironing and s...

Abstract

The invention discloses a manufacturing method of pure-cotton flame-retardant protective clothing, and belongs to the technical field of lifesaving devices. The manufacturing method is characterized by sequentially comprising the following steps: (1) measuring the shrinkage ratio of cotton cloth; (2) manufacturing clothing; (3) desizing and drying; (4) soaking with a flame retardant; (5) pressing sizing. The flame retardant clothing manufactured by the manufacturing method can be made into cotton cloth clothes at first, and then is subjected to the follow-up operation such as soaking with the flame retardant according to customer' requirements, so that the function failure or reduction of the flame retardant clothing due to out of date of a flame retardant, a functional fiber or cloth in the prior art is avoided; waste of expensive raw materials such as the flame retardant in which the clothing but not un-tailored cloth is socked is avoided; the flame retardant clothing combines cotton cloth rich in China and the flame retardant, so that the flame retardant clothing is comfortable to wear and low in cost, and meets the our national actual conditions better.

Description

technical field [0001] The invention belongs to the technical field of lifesaving devices, and in particular relates to a method for making pure cotton flame-retardant protective clothing. Background technique [0002] In high-temperature industries such as firefighting and smelting, strong radiant heat can rapidly melt, decompose and burn ordinary clothing, which can easily burn the skin of operators and threaten their lives. Due to the addition of flame retardant fibers in the fabric or the coating of flame retardants on the fabric, the flame retardant clothing can greatly slow down the burning speed, extinguish itself immediately after moving, and the burning part is quickly carbonized without melting or dripping Or piercing, giving people time to evacuate the burning scene or take off the burning clothes, reduce or avoid burns and scalds, and achieve the purpose of protection. Flame-retardant clothing has therefore become one of the necessary protective products for per...
