Problems solved by technology

At present, there are studies on the technology of using PEG crosslinking to finish pure cotton or cotton blended fabrics. However, there are defects such as the adjustment temperature range cannot meet the actual needs, the appearance of the finished fabric is sticky, and the strength loss is large. The practical value is poor, so it is rarely used.

Embodiment 1

[0033] 50% PEG-1000, 25% 2D resin, 3% MgCl 2 ·6H 2 0 / citric acid mixture (molar ratio 15:1), 3% NaCl is formulated as a phase-change finishing agent, kapok / cotton (50 / 50) blended knitted fabrics are immersed in the finishing agent for two hours, and then untreated Extrude the excess finishing agent that forms cross-linking, pre-baking at 80°C for 7 minutes, baking at 140°C for 3 minutes, soaping at 60°C for 10 minutes with a bath ratio of 2g / L, and then rinsing with water Clean, dry at 100°C, and finally use the PyrisIDSC differential tracing calorimeter of the American Perkin-Elme company to detect the absorption and exothermic properties of the sample, that is, the DSC curve, see figure 1 .

Embodiment 2

[0035] 20% PEG-600, 15% 2D resin, 2% MgCl 2 ·6H 2 O / citric acid (molar ratio 12: 1), 9% NaCl is made into phase-change finishing agent, impregnated kapok blended fabric (48% kapok, 48% cotton, spandex 4%) for 1 hour, and then rolled with conventional finishing machinery Squeeze out the excess finishing agent that has not formed cross-linking with a stick, pre-bake at 40°C for 10 minutes, bake at 160°C for 1 minute, and soap at 60°C for 20 minutes with a bath ratio of 2g / L. Then rinse with clean water, dry at 100°C, and finally use the PyrisIDSC type differential tracing calorimeter from Perkin-Elme, USA to test the sample to obtain the DSC curve, see figure 2 .

Embodiment 3

[0037] 80% PEG-800, 20% 2D resin, 8% MgCl 2 ·6H 2 O / citric acid (molar ratio 10:1), 5% K 2 SO 1 Make phase change finishing agent, impregnate kapok fiber for 5 hours, squeeze out excess uncrosslinked finishing agent with equipment, pre-bake at 100°C for 3 minutes, bake at 80°C for 5 minutes, use 2g / L Soaping at 60°C for 20 minutes, then rinsing with clean water, drying at 100°C, and finally testing the DSC curve of the sample with the PyrisIDSC type differential tracing calorimeter of the American Perkin-Elme company, see image 3 .

Abstract

The invention discloses a manufacturing method for kapok phase-change material that includes the following steps: taking preprocess to 5-100% kapok fiber, 0-95% cellulose fiber, 0-90% other fiber through refining technology of cotton fabric, dipping into phase-change finishing agent for 1-5 hours, extruding the rest finishing agent, pre-drying for 3-10 minutes at 40-100 degree centigrade, baking for 1-5 minutes at 80-160 degree centigrade, taking soaping for 10-20 minutes at 60 degree centigrade, cleaning by water. The benefit effect of the invention is that it achieves optimal temperature adjusting function for kapok, saves refrigeration and heating energy, improves the anti crease and humidity transmission capability.

Description

technical field [0001] The invention relates to a manufacturing method of a phase-change kapok textile material (fiber, yarn, fabric), in particular to a chemical manufacturing method of a kapok textile material with a phase-change temperature-regulating function within the temperature range of the earth's environment. Background technique [0002] At present, a major application of phase change materials is heat storage and temperature regulation products. With the shortage of energy and severe environmental protection problems, heat storage and temperature regulation products are getting more and more attention at home and abroad. Thermal storage and temperature-adjusting textiles are new high-tech textiles developed by chemical and physical methods. Generally, the phase-change substances contained on the surface or inside of textile fibers undergo a solid-liquid reversible phase transition after being cooled or heated to absorb and release heat. Delay temperature change o...
