Problems solved by technology

However, due to the particularity of temperature-sensitive materials, the air permeability of such textiles can only be "on" or "off" at a certain temperature. In addition, due to the high glass transition temperature (Tg) of PNIPAAm, the fabric feel will be affected to a certain extent

Embodiment 1

[0050] The percentages mentioned in this embodiment are all mole percentages. Thermosensitive microgels with linear response were synthesized using two monomers with different LCST values. Put a certain concentration of microgel into a clean cuvette, and use a nanoparticle size and molecular weight analyzer to measure the change of microgel emulsion with temperature. Include the following steps:

[0051] 1) the MEO 2 MA and OEGMA 300 The microgel synthesized with a molar ratio of 2:1 was formulated into a suitable concentration;

[0052] 2) Put the emulsion into a clean cuvette;

[0053] 3) Test the average particle diameter of the microgel emulsion every 5°C with a nanoparticle size and molecular weight analyzer.

[0054] Measure 3 times on the same sample at the same temperature and take the average value. The emulsion temperature range is 10-70°C. It can be seen that within 10-70°C, P(MEO 2 MA-co-OEGMA 300 -co-EGMA) microgel particle size decreases gradually with i...

Abstract

The invention relates to the field of textiles, and discloses a method for realizing linear regulation of comfort and anti-bacterial adhesion by crosslinking temperature-sensitive microgels on the surface of fabrics, comprising the following steps: 1) using temperature-sensitive microgels, crosslinking agents, catalysts and solvents 2) heat up and bake the treated textile to generate crosslinking reaction. The invention realizes the function of linear regulation of textile comfort and anti-bacterial adhesion, and is convenient to operate without affecting the original whiteness and flexibility of textiles; The reactive functional groups contained in the body and the reactive functional groups on the surface of the textile react with the carboxyl group contained in the crosslinking agent to form a covalent bond, and fix the temperature-sensitive microgel on the surface of the textile, which overcomes the general smart temperature-regulating textiles that only "open" or "off" function, so that the pores of the microgel film on the surface of the textile after finishing gradually increase with the increase of temperature and the surface of the fabric always maintains the hydrophilic property, thus realizing the function of linear regulation of textile comfort and anti-bacterial adhesion .

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for achieving linear regulation of comfort and anti-bacterial adhesion by cross-linking temperature-sensitive microgels on the surface of fabrics. Background technique [0002] In the daily wearing process of textiles, changes in external environment temperature / human body temperature will affect the comfort of wearing, so there is an urgent need for a material to change the comfort of textiles during wearing. Currently, there are two main approaches to obtain smart breathable textiles. One is to modify the fibers, such as adding phase change materials during spinning to prepare intelligent temperature-regulating fibers. The main phase change materials are paraffin, polyether, aliphatic polyester, polytyrethane, etc., but such fibers Due to the addition of phase change materials, the strength of the fibers is significantly reduced, and the binder used in the finishing process wi...
