Abstract
The invention relates to a durable colorless moisture absorption and sweat releasing composite finishing agent and a preparation method thereof, wherein the durable colorless moisture absorption and sweat releasing composite finishing agent comprises the following raw material components: the composite material comprises polyamide polyester polyether block copolymer, hydrophilic polyurethane polymer, polyethylene glycol diacrylate, antioxidant, sodium hydroxide, pH regulator, PVP and water. The moisture-absorbing and sweat-releasing composite finishing agent suitable for spandex, terylene and chinlon is obtained by adjusting the proportion of the raw material components, has good moisture absorption, washing fastness and quick-drying performance, and the treated fabric has no color change or yellowing and does not influence the hydrophilic placing stability, hand feeling, antistatic performance and fabric fastness of the treated fabric.
Description
Technical Field
The invention relates to the technical field of chemical industry, in particular to a durable colorless moisture absorption and sweat release composite finishing agent.
Background
The moisture-absorbing and sweat-releasing finishing agent is an essential chemical product in the clothing industry. Sweat is firstly absorbed by the fiber material and is transmitted to the outer surface of the fiber through the gaps in the fiber, and then is diffused into the air; after being absorbed by the fiber, the liquid sweat passes through the capillary holes and the grooves in the fiber and the gaps among the fibers and is absorbed, diffused and evaporated by the fiber through the capillary effect. According to the principle of moisture absorption and sweat releasing, the development of the moisture absorption and sweat releasing textile is mainly started from the aspects of moisture absorption and sweat releasing functional fibers, fabric physical organization structures, functional after finishing and the like. Common fiber base materials for moisture absorption and sweat releasing finishing mainly comprise spandex, terylene and chinlon, and other base materials such as cellulose fibers, polypropylene fibers, all cotton and other fabrics with better moisture absorption and air permeability are less applied. Different types of moisture wicking finish are used for different substrate materials.
The finishing agents used in production are roughly classified into the following types: acrylates, polyamines, polyurethanes, polysiloxanes and polyesters. The polyacrylate hydrophilic finishing agent is mainly prepared from a polymer of acrylic ester or diacrylate containing polyethylene chain segments, and the finished fabric is difficult to balance in hydrophilicity and hand feeling and has an unsatisfactory comprehensive effect.
The polyamine hydrophilic finishing agent is fixed on the surface of the fiber fabric through osmosis and film forming, is suitable for the nylon fabric, has the requirement on molecular weight distribution, and has the advantages of high molecular weight favorable for film forming and low molecular weight favorable for osmosis, improves the washability of the fabric, but has poor washability and is easy to yellow when being used alone.
The polyurethane hydrophilic finishing agent is a high molecular polymer formed by reacting polyisocyanate and polyether or polyester polyol under certain conditions. Patent document CN109853245A discloses a preparation method of a washable polyurethane type moisture absorption and sweat releasing finishing agent, belonging to the technical field of textile chemical industry. The water-fast polyurethane moisture-absorbing and sweat-releasing finishing agent comprises, by weight, 17-20 parts of polypropylene glycol, 4-5 parts of polyethylene glycol, 1-2 parts of methyldiethanolamine, 4-5 parts of isophorone diisocyanate, 8-9 parts of ethanol and the balance of water. After the finishing agent is adopted, the fabric can avoid the problems in the prior art, the moisture absorption and sweat releasing performance is greatly improved, the fabric is not compacted any more, air holes are not blocked any more, the heat exchange and the moisture exchange between the microclimate between the skin and the clothes and the external environment are normal, the stuffy feeling is not generated, the air permeability is good, the clothes can not be adhered to the skin, static electricity is not generated, and the comfort level of a user is improved. However, although the hydrophilic finishing agent has good wettability, the polyurethane is easily dissociated at low temperature.
