Description
Technical Field
The invention belongs to the technical field of textile printing, and particularly relates to a plurality of printed textiles added with PCM phase-change materials.
Background
PCM phase change materials may be classified as Organic (Organic) and Inorganic (Inorganic) phase change materials, and also as Hydrated salt (Hydrated Salts) and waxy (Paraffin Wax) phase change materials. The traditional cloth plays a role in keeping the normal temperature of a human body in the garment by controlling heat conduction, heat convection and heat radiation between the human body and the external environment, when the external environment temperature is lower than the normal body temperature of the human body, because the human body temperature is high and the environment temperature is low, a temperature gradient is generated between the human body and the environment, the heat of the human body can be emitted to the environment, people can feel cold, and aiming at the situation, the traditional solution is to properly increase the thickness of the cloth of the garment to reduce the heat exchange between the human body and the external environment so as to maintain the normal body temperature of the human body; on the contrary, when the external environment temperature is higher than the normal body temperature of the human body, the external environment can convey heat to the human body, so that people feel increasingly hot, and at the moment, the human body cannot dissipate heat through heat radiation, heat convection and heat conduction, so that the skin needs to perspire a large amount of sweat, and the heat can be taken away by utilizing the evaporation of the sweat to maintain the constant body temperature of the human body.
The following disadvantages exist after the traditional pigment printing: the fabric has rough hand feeling and poor air permeability, the rubbing fastness of the product in washing and dry and wet grinding is poor, the hand feeling of a printing part is poor, and especially the hand feeling of large-area printed fabrics is poor. The resin adhesive is gradually peeled off due to continuous rotation and stirring in the cleaning process, the quality of the adhesive is not stable enough, and film is formed too early in the printing process sometimes to cause defects such as a mosaic cylinder, a sticky knife edge and the like. With continuous washing or dry cleaning, the pigment printing gradually fades, the color becomes lighter and lighter, and the printed cloth can obviously fade after being washed for 10-20 times. The traditional PCM printing process only has single white mucilage printing, the color is single, the process is complicated, and in the process of preparing the sizing agent, when the coating reaches a certain concentration, a series of fastness indexes such as the reduction of washing fastness, the reduction of washing fading, the reduction of dry friction fastness, the reduction of wet rubbing fastness, the soft hand feeling, the easy screen blocking of the printing and the like can be caused.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides various printed textiles added with PCM phase-change materials, which are printed by water paste coating and/or glue paste coating, wherein the addition amount of the PCM phase-change materials in the raw materials for water paste coating printing and/or glue paste coating printing is 1-80 parts by weight. Through two printing processes, PCM phase-change materials can be added to the back and the front of the fiber textile fabric and the non-woven fabric in a mode of multiple printing color pastes, and the textile has a continuous cold feeling function and a constant temperature function.
The PCM phase-change material has the function of reducing heat exchange between a human body and the external environment and plays a role in heat insulation. Under normal conditions, the comfortable temperature of a human body is generally between 29 and 35 ℃, so that the PCM phase-change material with the phase-change temperature falling in the interval can be selected as a modifier of the textile fabric; for fibers for other applications, because the phase change temperature of the PCM phase change material is different, the phase change latent heat, the thermal conductivity coefficient and the material density affect the temperature regulation efficiency of the PCM phase change material, and the PCM phase change material with larger latent heat and density and rapid thermal conductivity should be generally selected. The volume change in the phase change process also has certain influence on the application, and the low thermal expansion coefficient is preferably selected. Meanwhile, the cycle heat storage performance is also an important index of the phase change characteristic. The phase change process must not bring any degradation and change, no supercooling phenomenon, no loss and no change in the washing and ironing process, and the service life of the PCM with practical value is generally more than 1000 thermal cycles.
The water paste pigment printing raw material comprises the following components in parts by weight: 1-15 parts of water slurry, 1-3 parts of dispersing agent, 1-80 parts of PCM phase change material, 1-50 parts of thickening agent, 0.2-1 part of defoaming agent, 5-30 parts of adhesive, 5-30 parts of cross-linking agent and 1-5 parts of non-reactive silicone oil. Wherein, the dispersant is used for preventing the printing from blocking the screen by fully stirring the disperse dye; the addition of the adhesive can effectively improve the washing fastness and the washing discoloration and fading; the use of the cross-linking agent can effectively improve the dry rubbing fastness and the wet rubbing fastness; the use of the non-reactive silicone oil can solve the problem that the fabric is not soft in hand feeling.
The water slurry coating is prepared by the following method, which comprises the following steps:
sequentially adding a dispersing agent and a PCM phase change material into the water slurry, and stirring to obtain a mixed solution 1;
diluting the thickening agent with 3-5 times of water, and slowly adding the diluted thickening agent into the mixed solution 1 under full stirring to obtain a mixed solution 2;
adding 50% of defoaming agent into the mixed solution 2 to obtain mixed solution 3, wherein the defoaming agent is added in two times, firstly adding 50% of defoaming agent into the mixed solution 2 to mix uniformly, stirring by using a stirrer, setting the stirring speed to be 200-400 r/min, and adding the rest defoaming agent while stirring;
and adding the adhesive, the cross-linking agent and the non-reactive silicone oil into the mixed solution 3 to obtain the water slurry coating added with the PCM phase-change material.
The formula material of the invention uses water paint, the color paste permeates into the cloth veins through the meshes to dye the fabric tissue fiber into the required color, and no coating with adhesive texture is formed on the printed pattern; the printed fabric added with the PCM phase-change material has good air permeability and comfortable and soft hand feeling, the PCM phase-change material is made of printing solid slurry made of polyurethane or acrylic ester, and the coloring principle is that molecular groups of a high-molecular bonding material in the solid slurry are combined with molecular groups in pigment to penetrate through and attach to fabric fibers to complete crosslinking so as to achieve the color fixing effect. By using the water-based paint with good dispersibility and the superfine filler, the grinding operation is cancelled on the premise of stably improving the product quality, the production process is simplified, and the production efficiency is improved.
In the steps of the invention, in the early dispersing stage, the dispersing agent is added in advance, which is helpful for dispersing, and simultaneously prevents or reduces the phenomenon that the slurry is stained on the wall, and improves the dispersing effect; after the PCM phase change material is added into the dispersant, the PCM phase change material can be uniformly dispersed in the water-based paint slurry; the thickening agent is diluted by water, and is slowly added under full stirring after the slurry is dispersed, so that the phenomenon that the emulsion is agglomerated or forms micelles due to overhigh concentration of the local thickening agent can be prevented; the defoaming agent is added into the slurry twice, so that the defoaming effect is better; when the defoaming agent is added, the stirring speed of the stirrer is controlled, so that the phenomenon that a large amount of bubbles are introduced in the production process to influence the printing quality of the coating is prevented; in order to ensure that the color fastness of the water slurry coating and the washing fastness of the PCM phase-change material meet the washing requirements, the solid slurry using amount percentage needs to be increased properly, or the adhesive/cross-linking agent is adopted to increase the color fastness of the water slurry coating and the washing fastness of the PCM phase-change material.
The adhesive cement is formed by mixing chemical adhesive and sizing agent, and various adhesive media are utilized to attach the mixed dye to the printed position of the clothes. The covering performance of the adhesive printing is good, and the adhesive printing can be used on various dark-colored fabrics; the mucilage printing pattern has high stereo degree, certain luster and better texture; meanwhile, the adhesive cement and dyes with various colors have good fusion, higher color reduction degree on patterns and bright printing color. The mucilage pigment printing of the invention further comprises white mucilage pigment printing and color mucilage pigment printing, wherein the white mucilage pigment printing comprises the following raw materials in parts by weight: 1-80 parts of PCM phase change material, 10-30 parts of transparent paste and 80-90 parts of overprint white glue; the white size coating can be directly used for printing deep color cloth, the fastness can be properly increased by adding transparent size, the printing effect of overprinting white size is good or bad, besides the fastness, the covering property, the elasticity and the whiteness are mainly considered, in the practical application, the mixing ratio of the overprinting white size and the transparent size can be adjusted by 10-30% according to the requirements according to different ground colors and different thicknesses of color block patterns. The raw materials for printing the color sizing agent coating comprise the following components in parts by weight: 1-80 parts of PCM phase change material, 10-30 parts of transparent paste, 10-30 parts of white glue paste, 1-10 parts of color coating paste and 1-5 parts of non-reactive silicone oil.
