Filled type cotton fiber and preparation method thereof

Abstract

The invention discloses a preparation method of the filled type cotton fiber. The preparation method of the filled type cotton fiber comprises the following steps: conducting a caustic scouring process on the cotton fiber or cotton fabrics; conducting a cleaning process; conducting modified preparation of functional substances; dispersing the functional substances in liquid ammonia; conducting a liquid ammonia treatment process; recycling the liquid ammonia; and dehydrating and stoving; The caustic scouring process is used for eliminating impurities in a center chamber of the cotton fiber and enabling most of the end ports of the center chamber of the cotton fiber to be opened, the modified preparation of the functional substances refers to put the cotton fiber into the liquid ammonia which is provided with functional particles in a diffusion mode to be treated, and the functional particles are enabled to be permeated into the center chamber and holes of the cotton fiber by means of a permeation function of the center chamber of the cotton fiber and the function which detaches hydrogen bonds of cellulose molecules. The invention further discloses a filled type cotton fiber. The cotton fiber prepared by the method has the advantages of being anti-bacterial, health-care, capable of releasing negative ions, ultraviolet-resistant and the like.

Description

technical field [0001] The invention relates to a cotton fiber and a preparation method thereof, in particular to a filling cotton fiber and a preparation method thereof. Background technique [0002] Cotton products are natural fiber products with high output, moderate price and comfortable wearing, which are widely loved by people. But with the improvement of the economic level, people's requirements for clothing are getting higher and higher. The requirement to add functionality to natural cellulose fibers is one of the points. One of the most convenient and quickest ways to add functionality to finished fibers or fabrics is post-processing. Most post-treatment methods are to coat the surface of fibers or fabrics after mixing functional finishing agents with binders, which will directly affect the feel of fabrics. As disclosed in Chinese patent 96200511.8, a kind of antibacterial drug layer with binder as the carrier, although endows the fabric with good antibacterial ...

Most of the post-treatment methods are to coat the surface of fibers or fabrics after mixing functional finishing agents with binders, which will directly affect the feel of fabrics

As disclosed in Chinese patent 96200511.8, a kind of antibacterial drug layer with binder as the carrier, although endows the fabric with good antibacterial effect, also affects the air permeability and feel of the fabric at the same time, and only relies on the binder functional substance and The bonding fastness of the fabric is not good. After washing several times, a large amount of functional substances will be lost, and the fabric will lose its specific functionality.
