Embodiment 1

[0027] The raw materials of the surface layer of the school uniform in this embodiment are cotton fiber and polyacrylonitrile fiber; the raw materials of the inner layer are hemp fiber and viscose fiber; wherein, the mass ratio of cotton fiber to polyacrylonitrile in the raw material of the surface layer is 6:1; The mass ratio of fiber and viscose fiber is 8:1.

[0028] Step 1: Add trimesoyl chloride to 30# paraffin at 40°C and mix evenly. The mass ratio of trimesoyl chloride and 30# paraffin is 1:10 to obtain mixture I; Min emulsified for 5 seconds to obtain an emulsion. Take ethylenediamine with a mass equal to 1% of the water phase emulsion, add dropwise to dissolve and emulsify, react at a constant temperature of 40°C for 30 minutes, and dry in vacuum to obtain microcapsules.

[0029] Step 2, polyacrylonitrile is dissolved in the sodium thiocyanate solution of 51wt%, obtains solution II, then microcapsule is added in the solution II, makes spinning solution; Polyacrylonitr...

Abstract

The invention provides a school uniform manufacturing technology based on a heat-storage warmth-keeping polyacrylonitrile fiber fabric. The school uniform manufacturing technology comprises the following steps of firstly, trimesoyl chloride is added to 30# paraffin with the temperature of being 40 DEG C, the materials are uniformly mixed and emulsified, ethylenediamine with the mass which is 1% ofthat of water-phase emulsion is taken, and a reaction is conducted for 30 minutes at the constant temperature of being 40 DEG C, so that microcapsules are obtained; polyacrylonitrile is dissolved ina 51wt% sodium thiocyanate solution, the microcapsules are added, and a spinning solution is obtained; the prepared spinning solution is extruded out of a special spinning nozzle for acrylic fiber wetspinning; extruded polyacrylonitrile fibers are cleaned and dried, and heat-storage polyacrylonitrile fibers are obtained; and finally, polyacrylamide is processed to form an aqueous solution with the mass fraction ranging from 15% to 20%, the prepared polyacrylonitrile fibers are immersed, and modified polyacrylonitrile fibers are obtained. The prepared fibers are high in heat efficiency, the heat storage capacity of the fibers is higher than the heat storage capacity reported in literature, and the fibers have the good physical and mechanical properties, the good wearability, the good processability and the good dyeing property.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, in particular to a school uniform manufacturing process based on heat-storing polyacrylonitrile thermal fiber fabrics. Background technique [0002] Clothing, as an indispensable item in human life, often attracts attention. It is understood that people's requirements for fabrics generally focus on: the fabric should be soft and smooth to the touch; Antibacterial and deodorizing, anti-ultraviolet, anti-radiation, heat insulation and anti-high temperature functions; the fabric has the function of moisture absorption and quick-drying; the fabric has excellent heat-humidity comfort performance and warmth retention performance; the fabric has good anti-pilling performance and tear resistance performance . [0003] With the rise of school uniforms, the market for school uniform fabrics has increased dramatically, and school uniform fabrics with different functions have emerged as the times ...
