Temperature-sensitive color-changing paint dyeing technology of textile fabrics

The invention discloses a temperature-sensitive color-changing paint dyeing technology of textile fabrics. The process flow is as follows: selection and composition of the temperature-sensitive color-changing paint; preparation of temperature-sensitive color-changing dye microcapsules; preparation and dyeing of a temperature-sensitive color-changing pigment printing paste, dehydration, and baking to obtain a temperature-sensitive color-changing fabric. The textile fabric is a fabric which is prepared by pretreatment of cotton, Tencel fiber, modal fiber, chemical fibre blended cotton (lanca, polyester cotton and nylon cotton), silk, wool and the like. Through combined actions of ambient temperature, temperature inside clothes and body temperature, the color of the temperature-sensitive color-changing textile obtained by the application of the dyeing technology changes when the surface temperature of the textile achieves or exceeds color-changing temperature; and when the temperature drops below the color-changing temperature, the textile turns to the original color. With the change of the temperature, the textile fabric shows unexpected color and pattern, and the pattern will change based on movement of the body. The color-changing fabric can be widely applied in T-shirt, trousers, swimsuit, casual gym suit, working clothes, children's clothing, curtain, toy and the like.

Polyester-cotton microcapsule disperse reactive dye one-bath dyeing technology

The invention discloses a polyester-cotton microcapsule disperse reactive dye one-bath dyeing technology. The technology comprises the steps of: S1, polyester dyeing: dipping a to-be-dyed polyester-cotton fabric in a dye solution containing microcapsule disperse dye, conducting heat preservation at 65-75DEG C, then performing heat preservation at 110-130DEG C, and carrying out cooling to 30-40DEG C, using chitosan to serve as the carrier of the disperse dye, and then conducting crosslinking curing; S2. cotton dyeing: adding a quaternary ammonium salt cationic etherifying agent, carrying out stirring reaction, then adding a reactive dye, performing heat preservation at 55-65DEG C, adding an organic solvent, conducting heat preservation at 70-90DEG C, then adding organic amine and sodium carbonate, and performing heat preservation at 60-100DEG C; and S3, aftertreatment: performing cooling to room temperature, and then carrying out primary washing, soaping and after-washing. The polyester-cotton microcapsule disperse reactive dye one-bath dyeing technology provided by the invention has the advantages of simple process, little pollution, wide dye applicability, uniform coloring, high color fixation rate and good level-dyeing properties.

The invention discloses a method for preparing ultraviolet color-changing printed fabrics. The prescription by weight percentage of fabric printing color paste is: X percent of ultraviolet color-changing dye, 60 percent of natural modified paste material with the lid containing rate of 10 percent, 0.5 percent of glacial acetic acid, 3 percent of urea, and the balance being water, wherein the mixture ratio of X percent of the ultraviolet color-changing dye in percentage by weight is: 0.2 percent of cationic violet 5BLH, 0.4-0.9 percent of cationic yellow X-10GFF, and 0.1-0.2 percent of cationic red X-5GN. A fabric printing process comprises the following procedures of taking a fabric, printing the fabric, steaming the fabric, washing the fabric, drying the fabric and obtaining a finished product. The parameters of a steaming process are as follows: the temperature of heating with superheated steam is 125 DEG C, and the heating time is 30 min. The method overcomes the problems of hand feeling, free formaldehyde, etc. caused by applying adhesive to prepare ultraviolet color-changing printed fabrics in the prior art, has simple-convenient process and low cost, does not change the prior style of fibers, and is excellent in wet fastness and rubbing fastness. Tests show that: the fabric is environmentally friendly and safe, does not contain 23 carcinogenic aromatic amines or heavy metal ions harmful to human body, and is broad in market prospects.

A low-temperature dyeing method of PLA/PHBV blended yarn comprises steps of: wetting the PLA/PHBV blended yarn into deionized water of 60-90 degrees centigrade, cleaning for 15-30min; taking disperse dye of 0.5%-2% of the weight of the blended yarn, dissolving the disperse dye into the deionized water to form a dye liquor, putting the blended yarn into the dye liquor, dyeing as per a bath ratio of 20-30:1, firstly heating up the dye liquor to 65-75 degrees centigrade by 2-4 degrees centigrade/min, heating up to 90-100 degrees centigrade by 1-2 degrees centigrade/min, maintaining the temperature for 40-60min; then cooling down to 50 degrees centigrade by 3-5 degrees centigrade/min, and taking out the blended yarn; reduction clearing the blended yarn, wherein the reduction clearing solution comprises 0.5-1g/L of sodium hydrosulfite and 0.5-1g/L of anhydrous sodium carbonate; the temperature of the reduction clearing solution is 75-90 degrees centigrade; the bath ratio is 20-30:1; and the reduction clearing duration is 20-30min. The low-temperature dyeing method of PLA/PHBV blended yarn solves the low-temperature dyeing problem of the PLA/PHBV blended yarn; the method saves energy and reduces production cost, and it has the advantages of deep dye color, uniform dyeing effect, washing fastness, and good crockfastness.
