Description
Technical Field
The invention relates to the technical field of textile fabric finishing, in particular to a method for improving the wearability of a brocade spandex printed textile fabric.
Background
Along with the development of textile industry and the increase of demand of people on sports fabrics, the polyamide-spandex fabrics are also increased year by year, and the polyamide-spandex printed fabrics have the characteristics of beautiful patterns, bright color, excellent elasticity and wear resistance and the like, are widely applied to the garment industry and can be used for manufacturing climbing wear, underwear, outdoor sportswear, swimwear trousers, outdoor clothing, socks and the like, while the polyamide-spandex printed fabrics have the wide defects of poor hand feeling and poorer wet processing fastness and air permeability than dyed fabrics due to the use of printing sizing agents and cross-linking agents in the printing process, and have the prominent problems of hard hand feeling, poor fastness, air permeability and poor differential dry hydrophilicity particularly when the polyamide-spandex printed fabrics are fully dyed in dark color or extra dark color, so that the problems always plague numerous textile manufacturers, in order to improve the wearing comfort of the polyamide-spandex printed fabrics, improve the hand feeling, the moisture absorption and perspiration performance and improve the color fastness and the hydrophilicity, meanwhile, the core problem of the brocade spandex printed fabric is also considered for environmental protection.
The invention patent publication No. CN106223063A only mentions hydrophilic finishing of printed fabrics, but does not mention how to improve color fastness and moisture permeability and improve hand. The paper "brocade spandex fabric color fixing and moisture absorption and perspiration function finishing" written by Liao teacher's organ in Shanghai textile science and technology journal discusses the improvement of color fastness and moisture absorption and quick drying performance of acid dye dyed brocade spandex fabric, but does not mention how to improve the color fastness, moisture absorption and perspiration and hand feeling of printed brocade spandex fabric. The processing mode of improving the color fastness of the brocade spandex dyed and printed fabric is discussed in the 'discussion of color fastness improving method of brocade spandex knitted fabric' by the article of Wangmeng Wei, and how to improve the hygroscopicity, quick drying property, hand feeling and the like of the brocade spandex fabric is not mentioned.
In the actual production of mill, the wet processing fastness of the brocade spandex printed fabric is poor, the production requirement and the customer demand can not be well met, especially the perspiration resistance and the soaping color fastness are poor, and the common process for improving the color fastness is to fix the color by using an acidic color fixing agent, and the action principle of the color fixing agent is as follows: under the acidic condition, a film is formed on the surface of the nylon spandex fabric through the finishing of the color fixing agent, so that the contact chance of the dye and water is greatly reduced, the probability of the dye dissolving in the water is greatly reduced, and the fabric is not easy to fade during wet treatment such as washing, sweat soaking and the like; however, the existing acidic color fixing agent in the market can form a protective film on the surface of the fabric, and simultaneously, the fabric has hard hand feeling and poor water absorption; most of the nylon spandex fabrics are used as underwear and sports fabrics, a human body can generate a large amount of sweat during sports, if the sweat on the surface of the skin cannot be rapidly discharged to the outer surface of the clothing to be quickly evaporated, the wearing comfort is poor, at present, a printing and dyeing mill tries to improve the moisture absorption performance and the hand feeling by adding other finishing agents, but the color fixing effect of an acidic color fixing agent can be reduced after finishing by using an after-finishing auxiliary agent, and the nylon spandex printed fabrics often have the problems that the color fastness, the hand feeling, the hydrophilicity and the quick drying cannot be considered at the same time.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a method for improving the color fastness, air permeability, hydrophilicity, quick drying property and handfeel multiple wearability of the brocade spandex printed fabric so as to solve the industrial problem that the finished product of the brocade spandex printed fabric cannot give consideration to both the color fastness and the handfeel, and can absorb moisture and dry quickly. The finishing process is simple to operate, does not need to additionally increase the equipment cost, and does not pollute the environment.
The technical scheme for solving the technical problem is as follows: a method for improving the wearability of a brocade spandex printed fabric comprises the following steps: 1) providing a piece of steamed and unwashed printed cloth; 2) adopting 0.5-1.5 g/L washing fixing agent DM-2532N for continuous washing, wherein the bath ratio is 1: 15-20, adjusting the pH value of the working solution, washing at room temperature for 2min for the first time, washing at room temperature for 2min for the second time, washing at 40-45 ℃ for 3min for the third time, washing at 40-45 ℃ for 3min for the fourth time, discharging liquid after each washing, washing with cold water, dehydrating and drying for color fixation; 3) and (3) fixation: cleaning a color fixing agent DM-2532N X% (o.w.f), wherein the amount of water is 1-X% (o.w.f), and the range of X% is 3.0-8.0% (o.w.f); bath ratio of 1: 8-15, adjusting the pH value of the working solution, fixing color at 60-65 ℃ for 35-45 min, washing with cold water, dehydrating and drying, and finishing; 4) moisture absorption and quick drying and hand feeling finishing: 20-30 g/L of multifunctional finishing agent DM-3545N and 30-40 g/L of silicone oil T618 are adopted, the first soaking and the first rolling are carried out, the rolling residual rate is 70 +/-5%, and the drying is carried out at 110-120 ℃.
The invention has the beneficial effects that: the DM-2532N used in the invention has cleaning and color fixing functions, the pH value of a 1% aqueous solution of the DM-2532N is 1.5-2.5, the aqueous solution is acidic, acid adjustment is avoided during use, the aqueous solution is convenient for direct use in a printing and dyeing mill, and no formaldehyde is detected from a DM-2532N stock solution, so that the environmental protection requirement of an order of the printing and dyeing mill can be met. The multifunctional finishing agent DM-3545N is thermal reaction type polyurethane with a special structure, is used for hydrophilic, quick-drying finishing and soft finishing of brocade spandex printed fabrics, endows the fabrics with washable, plump and soft comfortable handfeel, endows the fabrics with excellent crease-resistant performance and easy decontamination function, greatly improves the wearing comfort of the fabrics, and is a high-quality functional finishing agent. The method can improve the hydrophilicity of the brocade spandex fabric to be less than 5s, and improve the quick drying property: the water evaporation rate of the fabric reaches over 90 percent in 30 minutes, and the hand feeling is improved to be soft and smooth.
