The fabric obtained by the invention has the functions of antibiosis, mite prevention, ice feeling and the like, is safe and environment-friendly, has good washing resistance, and can solve the problems of few functional types, non-washing resistance, poor size stability and the like of the current textiles.
In some embodiments of the present invention, the method specifically includes the following steps: spinning, weaving, singeing, refining, liquid ammonia finishing, dyeing, drying (scutching), post-finishing, tentering, baking and preshrinking.
The yarn is formed by blending metal ion modified fiber and cellulose fiber; the cellulose fiber is one or more of cotton and hemp, the metal ion modified fiber is modified chemical fiber with metal ions distributed in the fiber, and can be short fiber or filament, the linear density is 0.5dtex-3dtex (preferably 1.0-2.5dtex), and the length is preferably 30-45mm, or the titer of the metal ion modified synthetic filament is 30D-180D, preferably 50D-120D.
Taking a polyester substrate as an example, the metal ion modified polyester fiber is a functional polyester fiber which is generally formed by taking an antibacterial metal material as a spinning auxiliary agent and performing melt spinning processing; common polyester fiber is commonly called terylene, and is synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and dihydric alcohol, and is called PET fiber for short. In certain embodiments of the present invention, polyamide or polyacrylonitrile fiber substrates may also be used.

The invention preferably selects the size specification of the raw material, controls the yarn strength and the like, and is beneficial to the subsequent preparation of the fabric meeting the requirements.
The coefficient of variation of the strength is as follows: the degree of variation in yarn strength is expressed as the ratio of the standard deviation of single yarn strength to its average breaking strength. Single yarn breaking strength: the ratio of the breaking strength of a yarn to its linear density is expressed in centinewtons per tex (CN/tex).
After the blended yarns are obtained through spinning, the blended yarns are woven by a circular machine or a shuttle loom to produce grey cloth; the weaving step is a known method.
