Cotton padding and preparation method thereof

Abstract

The invention relates to a cotton padding, which comprises a cotton padding core, gauze screens and non-woven fabrics. Both upper surface and lower surface of the cotton padding core are provided with a layer of gauze screen and a layer of non-woven fabric in turn; the peripheries of the non-woven fabrics arranged on the upper surface and the lower surface are integrally quilted along the peripheral boundaries of the cotton padding core; the cotton padding core consists of the following components: cotton, hollow fibers, low-melting-point fibers and natural bamboo fibers; and the hollow fibers are at least one of far infrared hollow polyester short fibers, antibacterial polyester hollow fibers, bamboo carbon hollow polyester fibers, three-dimensional crimped hollow fibers and seven-hole polyester fibers. A preparation method comprises the following steps of: mixing, opening, combing, processing by using a random roller, paving, compacting, processing at a constant temperature, shaping, laying a net, rubbing, and reshaping. The components are reasonably proportioned, the processing technology is simple, and the prepared cotton padding has the characteristics of no caking, bacteria resistance and inhibition, health care, moisture absorption and air permeability, and is soft and fluffy and suitable for industrial production.

Description

technical field [0001] The invention discloses a batt and a preparation method. Background technique [0002] Existing cotton tires are usually made of lint through cleaning, loosening, carding, molding, spreading mesh, and grinding; it has the characteristics of good warmth retention and strong hygroscopicity; but due to the strong moisture absorption of cotton, the cotton The fiber is relatively straight, and the resilience is weak, and the cotton fiber almost loses the resilience after moisture absorption; especially, the moisture absorbed by the cotton cannot volatilize over time, causing the cotton batt to harden, and then the cotton batt loses its proper warmth retention function; In addition, because more cotton fibers are exposed at the meshes of the gauze and cotton tire after grinding, after the cotton tire is put into the quilt cover, the cotton fibers exposed at the gauze and the mesh are bonded to the quilt cover to a certain extent. The unit bonding force is s...

Problems solved by technology

[0002] Existing cotton tires are usually made of lint through cleaning, loosening, carding, molding, spreading mesh, and grinding; it has the characteristics of good warmth retention and strong hygroscopicity; but due to the strong moisture absorption of cotton, the cotton The fiber is relatively straight and has weak resilience, and the cotton fiber after moisture absorption almost loses its resilience; especially as time goes by, the moisture absorbed by the cotton cannot volatilize, causing the cotton batt to harden, and then the cotton batt loses its proper warmth retention function; In addition, since the gauze and the cotton tire are ground, there are more cotton fibers exposed in the mesh. The unit adhesive force is stronger than that of cotton fiber, and it is easy to cause the gauze and cotton wool to separate after changing the quilt cover many times
