The past and present of cotton spunlace non-woven fabrics

Non-woven fabrics, also known as non-woven fabrics, non-woven fabrics, non-woven fabrics, etc., in short, are fabrics made without weaving. It does not have to go through the traditional weaving method, but uses the fiber's own adhesion or the friction between fibers, or a cloth-like fiber product made of an external adhesive. Non-woven fabrics have some characteristics of textile fabrics, but also have special properties different from textile fabrics. They are widely used in building decoration industry, automobile industry, daily necessities, medical and health industry, military and national defense and other aspects. advantage.

A brief history of the development of non-woven fabrics

The origin of non-woven materials

The origin of non-woven materials can be traced back to ancient China thousands of years ago.

Felt products---needle-punched felt, acupuncture pad

silkworm spinning into brocade--spinning method

Modern non-woven technology development

Non-woven is a new non-woven technology in the textile industry. It has a simple industrial process. The advantages of high production efficiency, superior product performance, wide range of raw material sources and diverse product uses have made it rise rapidly and soon become a world-wide new industry with unlimited potential and rapid development. Chaoyang Industry'. The international non-woven industry started in 1960, with an average annual growth rate of 6%-8%. China's non-woven industry started in 1978. In the past 40 years, the average annual growth rate has been as high as 28%. After years of development, China has become the world's fastest-growing non-woven industry and the largest country.

Non-woven fabrics are divided into spunbond non-woven fabrics, melt-blown non-woven fabrics, hot-rolled non-woven fabrics, knitted non-woven fabrics, and spunlace non-woven fabrics according to different manufacturing processes. What we are going to talk about today is spunlace non-woven fabrics.

Advantages of cotton spunlace non-woven fabrics

Cotton fibers are the most natural fibers used in spunlace non-woven fabrics, because:

1 ) Cotton fiber is a fiber that is widely accepted by consumers, not only because cotton products have been produced and used for a long time, but also because cotton fiber is the purest form of cellulose found in nature, more than any other plant fiber. Has better physical and chemical uniformity.

2) Cotton fiber is a highly hygroscopic fiber, so it is especially suitable for the absorption of bodily fluids, such as urine, blood and other liquids, and can be used for bandages, wound dressings, absorbent pads (makeup removal), Hemostatic tethers, surgical gauze, cotton swabs, etc.

3) Cotton fiber is a kind of natural breathing fiber, which can effectively prevent the passage of liquid, but allow the passage of gas and water vapor. This property makes cotton fibers more suitable for making products that are in close contact with the human body.

4) In the wet state, cotton fibers have higher strength (as opposed to viscose), and do not have the typical slippery feel of synthetic fibers, which is especially suitable for health care products that require contact with the skin. care supplies.

5) In the production process of the cotton spunlace non-woven fabric, clean water is used to make the fibers entangle each other without adding any chemical substances, and there will be no pollution after degradation.
