Background
With the development of economy and the change of life quality of people, people pursue more and more diversification for living goods, the requirement on the comfort of textiles is increasingly improved, and in order to meet the requirement of users, the existing textiles can attach components with certain functions to the surfaces of textile fibers through a padding finishing method, so that the textiles are endowed with the functions of special fragrance, skin care, moisture retention, temperature regulation and the like. However, the textile finished by the existing padding finishing method has the defects that the effective components are only adhered to the fiber surface of the textile in an adhesion mode, and the textile is easy to lose function due to falling off after long-time use, so that the textile cannot keep corresponding functions for a long time.
Disclosure of Invention
The invention aims to overcome the defects or problems in the prior art and provide a textile finishing method which can effectively prolong the effective period of the functional effect on the textile.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method of finishing a textile, comprising: a primary padding process: placing the textile to be finished in the microcapsule finishing liquid A for padding treatment, washing and drying; a secondary padding process: placing the textile obtained after the primary padding into the microcapsule finishing liquid B for padding treatment, absorbing water and drying; and a third padding process: placing the textile obtained after the secondary padding into the microcapsule finishing liquid C for padding treatment and drying to obtain a finished textile; wherein the yarns in the textile to be finished have micropores; the microcapsule finishing liquid is a dispersion liquid containing microcapsule particles, the concentration of the microcapsule particles in the microcapsule finishing liquid A is 5-15g/L, the concentration of the microcapsule particles in the microcapsule finishing liquid B is 70-80g/L, and the concentration of the microcapsule particles in the microcapsule finishing liquid C is 30-50g/L.
Further, the microcapsule finishing liquid C also comprises a binder with the concentration of 15% -25%, wherein the binder is one or more of waterborne acrylic resin, waterborne polyurethane resin, waterborne epoxy resin or waterborne organic silicon resin.
Further, in the primary padding procedure, the padding temperature is 110-130 ℃.
Further, in the secondary padding process, the textile obtained after primary padding is padded in the microcapsule finishing liquid B for multiple times.
Further, in the third padding process, the textile obtained after the second padding is padded in the microcapsule finishing liquid C for multiple times, and the padding is stopped when the exhaustion rate reaches 65-75%.
Further, the textile to be finished is obtained by the step of punching the textile to be pretreated before the step of padding for one time; the textile to be pretreated is formed by weaving protofilament yarns with closed micropores; the hole opening process comprises the following steps: placing the textile to be pretreated into a lye tank, soaking for a preset time, taking out and washing, then adjusting the pH of the washed textile to 6-7 by using a weakly acidic solvent, and dehydrating.
Further, a sodium hydroxide solution with the concentration of 98% is filled in the lye tank, and the mass of the sodium hydroxide solution is 8% -10% of the weight of the textile to be pretreated.
Further, in the three padding procedures, the drying temperature is 130-150 ℃.
As can be seen from the above description of the present invention, the present invention has the following advantages over the prior art:
in the textile finishing method, the textile with micropores on the yarn is the finishing object, and the micropores on the yarn of the textile enable the microcapsule particles to enter and be fixed in the micropores, so that the effect provided by the microcapsule particles cannot be reduced or eliminated due to washing, and the effective period of the functional effect on the clothes made of the textile can be effectively prolonged.
The textile to be finished is placed into the microcapsule finishing liquid A with lower concentration, the low-concentration microcapsule padding treatment can be firstly carried out on the textile surface, and at the moment, microcapsule particles can enter partial yarn micropores and reach the inside of yarn fibers; in the process, the microcapsule particles in the microcapsule finishing liquid A can obtain larger kinetic energy by increasing the padding temperature, so that the microcapsule particles can more easily reach micropores, and because the concentration of the microcapsule particles in the microcapsule finishing liquid A is lower, enough space is provided in the finishing liquid for the movement of the microcapsule particles, so that the microcapsule particles can enter deeper positions in the micropores of the yarn after the process;
after finishing the padding procedure for one time, the textile is simply washed, microcapsules which enter the micropores in the washing process are not easy to fall off, but most of the microcapsules adhered to the surface of the textile fall off due to washing, so that enough space is reserved for the attachment of the microcapsules in the subsequent padding procedure;
in the secondary padding process, the concentration of the microcapsule finishing liquid B is high, the textile is padded repeatedly in the process, because the microcapsule particles have extremely small volume and large surface energy, aggregation is easy to occur, in the primary padding process, a small amount of microcapsule particles are fixed on the textile, the microcapsule particles can be used as a core for aggregation in the secondary padding process, a large amount of microcapsule particles are induced to aggregate and accumulate in micropores of the textile, the fixing effect of the microcapsule particles forming the aggregation effect in the micropores of the textile is good, and the microcapsule particles are not easy to fall off from the textile after washing;
and then carrying out a third padding process, wherein the textile is dried only by simple water absorption in the second padding process, so that the microcapsule particles which are just attached to the textile do not fall off due to the washing process, and in the third padding process, the textile is padded in the microcapsule finishing liquid C under the action of the binder, wherein the concentration of the microcapsule finishing liquid C is medium, the microcapsule finishing liquid C can be adhered to the surface of the textile through the binder and can further fix the microcapsule particles in micropores, so that the microcapsule particles can be attached to the textile for a long time on the premise of improving the efficacy of the microcapsule particles.
In addition, the tapping process is used for tapping the raw yarn, the raw yarn with micropores is generally in a micropore closed state when leaving a factory, so that the raw yarn needs to be tapped by alkali liquor, and in the process, the concentration of the alkali liquor in the alkali liquor tank and the mass ratio of the alkali liquor can be adjusted, so that the raw yarn is provided with enough micropores, and the raw yarn is distributed uniformly.
