Fabric and manufacturing process thereof

Abstract

The invention relates to a fabric with an electromagnetic shielding function. The fabric with the electromagnetic shielding function is made of composite yarn with the electromagnetic shielding function. The composite yarn comprises a yarn core and a covering layer. The yarn core is made of a branch of conductive fibers which are polyester fibers, and the surface of the polyester fibers is formed through eletcroless copper plating. The covering layer comprises a first fiber and a second fiber, the first fiber is covered and wound outside the core yarn in the first direction, the second fiber is a bamboo charcoal fiber which is covered and wound outside the covering layer formed by the first fiber in the second direction, and the first direction is opposite to the second direction. According to the fabric with the electromagnetic shielding function, comfortable wearing performance can be obtained from the first fiber, such as permeability and no skin irritation, the fabric does not include precious metals and toxic substances, is environment friendly and brings no health risks, and the shielding effectiveness for 0.1-15GHz electromagnetic radiation emitted by commonly-used appliances is greater than 50dB.

Description

technical field [0001] The invention belongs to the technical field of textile materials, more specifically, the invention relates to a functional woven cloth and a manufacturing process thereof. Background technique [0002] With the continuous improvement of productivity and the rapid development of science and technology, and the advent of the electrical age, electromagnetic radiation has become the fourth largest pollution source after water, air, and noise, and has become an invisible "killer" that endangers human beings. A large number of facts have proved that long-term exposure to electromagnetic radiation can lead to headaches, dizziness, memory loss, neurological disorders and other symptoms. Conductive metals can reflect, absorb, and offset electromagnetic waves, thereby reducing electromagnetic radiation. Electromagnetic wave shielding fabric is a commonly used anti-electromagnetic radiation material. [0003] The preparation method of electromagnetic wave shie...

AI Technical Summary

Problems solved by technology

[0003] The preparation method of electromagnetic wave shielding fabric mainly has the following two methods: (1) Spinning metal filaments and fabric fibers together into cloth, the electromagnetic wave shielding effectiveness is related to the content of metal wires, and the metal content of currently commercially available electromagnetic wave shielding fabrics is about 25% , the electromagnetic wave shielding performance is good, but its biggest disadvantage is that it has poor washability, cannot be folded repeatedly, and the metal wire is easy to break, which limits its application range.

(2) The fabric is placed in the chemical plating solution, and the metal layer is chemically plated on the surface of the fabric to obtain an electromagnetic wave shielding fabric, acid roughened, SnCl 2 Sensitization, PdCl 2 The disadvantages of steps such as catalysis and formaldehyde reduction are that the electroless plating step is complicated, and there are many heavy metal residues, and it also contains toxic reducing agents, and contains precious metal substances, and the cost is expensive

In addition, the feel, air permeability and comfort of the fabric also need to be improved.
