Problems solved by technology

[0004] At present, the modification of shirting fabrics is mostly through post-finishing, mainly by dipping the fabrics in the finishing solution, but most of the multi-functional shirting fabrics are only dried and interacted with related components, and no groups or bonds have occurred, and the degree of mutual bonding is relatively low. Poor, short duration of efficacy
For example, the Chinese invention patent whose patent notification number is CN101463556A discloses a kind of negative ion knitted fabric and its production process, adopts the negative ion finishing liquid and softener of 20-40g / L of fabric padding, and dries under the condition of 80-110 ℃, Then stretch at a high temperature at 150-180°C to obtain a knitted fabric that can release negative ions. However, tourmaline itself, the negative ion generator, has no groups and cannot form valence bonds with fibers. The tourmaline can only be squeezed by the pressure of the extrusion roller. The particles are temporarily fixed on the surface of the fabric, and the effect of this fabric releasing negative ions will not last long

Abstract

The invention provides a preparation method of a shirt fabric. Take polyethylene terephthalate particles and add them to a reactor, heat and melt them, then cool down and add polyvinylpyrrolidone and polyethylene glycol, and stir for reaction; then add ethanol, and ultrasonically Stirring; porous polymer melted electrospinning solution after centrifugation; three parts of polymer melted electrospinning solution were poured into the first micropump, the second micropump and the third micropump respectively, and the coaxial nozzle was used as a jet stream The spinneret is vacuum-dried to obtain nano-porous fiber bundles; nano-porous fiber bundles are modified to obtain antibacterial negative oxygen polymer fibers; cotton fibers are modified to obtain hygroscopic cotton fibers; modified polymer The fibers are warp yarns, the modified cotton fibers are weft yarns, and the shirt fabric is obtained after spinning, warp yarn package yarn dyeing, weaving and finishing.

Description

technical field [0001] The invention relates to the technical field of shirt fabric preparation, in particular to a multifunctional shirt fabric and a preparation method thereof. Background technique [0002] With the development of society, shirts are deeply loved by consumers such as business people. In summer, consumers have a great demand for shirts, and various clothing brands will launch various shirt products with various styles and novel styles. Among them, pure cotton shirt fabrics are made of natural cotton fibers through spinning, weaving, singeing, mercerizing, shaping and pre-shrinking. Because cotton fibers have properties such as softness, moisture absorption, warmth, and breathability, they are also Catering to consumers' back-to-basics consumption concept, it is a popular shirt product in the market; but pure cotton shirts have poor shape retention, are easy to wrinkle, and are easy to deform. [0003] As the most widely used chemical fiber, polyester fibe...
