[Common textile manual] electric blanket

It is a bed warmer that is composed of textiles and electric heating elements. It is a blanket that uses electricity to generate heat through electric heating elements to keep warm and keep warm. It consists of three parts: a core, is an electric heating element, generally using a nickel-chromium wire with a diameter of about 0.1mm, a high-insulation waterproof convolute combination heating element with an outer insulating material (such as polyethylene, nylon, etc.); 2 , Generally using acrylic carpets, cotton blankets, corduroy, satin, etc., there are plaids, color bars, printing, jacquard, etc., colorful and colorful; 3 lining, generally flannel. The electric heating element is sewn on a layer of cotton cloth of appropriate length and width, and the fabric and the lining are sewn up and down. Electric blankets are divided into high, medium and low grades, and the low grade is only two layers of fabric. The electric heating element is sewn to the inside of the material. The edge type is divided into two types: roll and not roll.

Electric blankets generally use cotton or chemical fiber yarns as raw materials. The commonly used warp yarns are 18texX2 (32/2 English), 36tex (18 English), and 97texX2 (6/2 English) weft yarns. Using Jacquard weaving machine, weaving process, woven into a corrugated hollow cotton blanket with a certain regularity and quantity, and then after treatment of double-faced nap, in its pre-designed hollow part, penetrating the high insulation waterproof type spiral combination Heating elements (The mechanical properties of the components such as voltage resistance, tensile strength, and bending resistance shall comply with the requirements of the International Electrotechnical Commission TEC and the former Ministry of Light Industry SG 277-82). There are also simpler electric blankets that use various types of flannel sutures and embedded heating elements. The quality of the blankets is slightly worse than that of specialized hollow fabrics.

specification

There are two specifications for single and double: single electric blanket width is 83 ~ 90cm, length is 167 ~ 185cm. The double electric blanket has a width of 135~140cm, a length of 167~185cm, and a mass of 0.5~0.7kg/bar. Colors are red, camel, fruit green, golden and so on. There are loose flowers, strips, and geometric patterns on the surface of the carpet. The 3cm-wide grosgrain edge material is used for four bread edges and looks like a cotton blanket.

Electric blankets have high safety requirements. Because of the double insulation of the heating element, the pressure resistance is better. General use 220v home power supply, equipped with two high and low temperature switch indicator, can cut off the power line at the same time. The power consumption is: 40~50w for single blankets, 20~25w for low temperatures, 80~100w for double blankets, and 40~50w for low temperatures.

use

The advantage of the electric blanket is that it is full of suede, soft texture, safe and warm, and is mainly used for heating insulation.
