Problems solved by technology

At present, the spindle transmission of high-speed ring spinning machines in the world is above 22,000 rpm. The traditional cotton spindle belt and rubber spindle belt have low constant elongation strength, low transmission strength, small friction surface fabric friction, easy to lose and difficult to rotate. Realize high-speed operation of 22,000 rpm and above
Although ordinary polyester spindle tape has slightly higher elongation strength, it is not resistant to high temperature and has a short service life.
[0003] Aliphatic polyurethane dispersions are generally used in clothes, (rain) clothes, shoe fabrics and luggage materials. They can be top-coated or primer-coated. Generally, they can improve the adhesion of fabrics, improve the clarity of leather textures, and impart softness and fineness. The feel and can improve the low temperature resistance of leather, but there is no publication of its application in the high fixed stretch spindle belt

Abstract

The invention discloses application of an aliphatic polyurethane dispersion. The aliphatic polyurethane dispersion is applied to a fabric layer of a high modulus spindle tape. 20% of the aliphatic polyurethane aqueous dispersion is added with a water-based crosslinking agent of isocyanate or melamine with 2-5% of mass fraction for stirring for 2-4 hours, and the fabric layer is treated. The treated fabric layer has good stiffness, high 1% modulus strength and stable size. The fabricated high modulus spindle tape has high modulus strength and soft tape body.

Description

technical field [0001] The invention belongs to spindle tape technology, and in particular relates to the application of an aliphatic polyurethane dispersion. Background technique [0002] In recent years, with the rapid development of textile equipment, the speed of spinning frame spindles has gradually increased, and the requirements for spindle tapes that provide power transmission are also getting higher and higher. At present, the spindle transmission of high-speed ring spinning machines in the world is above 22,000 rpm. The traditional cotton spindle belt and rubber spindle belt have low fixed elongation strength, low transmission strength, small friction force of friction surface fabric, easy to lose rotation, and difficult to rotate. Realize high-speed operation of 22,000 rpm and above. Although ordinary polyester spindle tape has slightly higher elongation strength, it is not resistant to high temperature and has a short service life. [0003] Aliphatic polyuretha...
