Tensile strength and softness control method of non-woven fabrics

Non-woven fabric is a kind of fabric that does not require spinning or weaving. It only orients or randomly spun short fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical methods. reinforced.

Simply put: it is not interwoven and braided by yarns one by one, but the fibers are directly bonded together by physical methods.

Non-woven fabrics have changed the original textile theory, and are widely used because of their wide application, low cost, high output value, fast production speed, and short technological process.

Because the non-woven fabric is produced from polypropylene, if it is too hard, it will be relatively brittle, and the tensile force is very poor, and the non-woven fabric is prone to cracking.

Most manufacturers prefer to make hard materials, because the fabric with the same gram weight is much thicker than pure materials after the fabric is hard.

The production of hard materials is a process commonly used by non-woven fabric manufacturers, because the fabric will feel thinner when it is soft, and the soft materials will feel very soft and close to real knitted fabrics, and the fabric has good toughness. Strong and not easy to tear.

The non-woven fabric with high temperature will feel harder, and the fabric with lower temperature will feel softer. The non-woven fabric requires a soft and hard texture, which is achieved by controlling the temperature during the production process.
