Description

Crease-resistant easy-care suit fabric
Technical Field
The invention relates to an anti-wrinkle non-ironing suit fabric, and belongs to the technical field of suit fabrics.
Background
Along with the continuous improvement of living standard of people, the requirement on clothes is higher and higher, and the fabric is used for manufacturing the material of the clothes, and is one of three elements of the clothes, and the fabric not only can explain the style and the characteristics of the clothes, but also directly controls the expression effect of the color and the shape of the clothes. The research on the western-style clothes fabric commonly used in the market at present and the western-style clothes fabric of the brand man at home and abroad discovers that the high-grade western-style clothes fabric at home and abroad is not limited to high-grade materials such as wool or cashmere any more, and in addition, cotton, hemp and silk materials are widely applied to the western-style clothes.
Nowadays, the domestic production of such casual formal suit enterprises is beginning to emerge. According to the comment of the clothes market sales situation, the leisure style western-style clothes obviously increase in the sales proportion, and according to the analysis of experts, the trend is further strengthened. The cotton fiber has excellent wearability and is ideal clothing and home textile fabric, but the cotton fiber has poor elasticity, and the fabric is easy to wrinkle after being washed, so that the various requirements of modern people on pursuing healthy, comfortable, convenient and fast life are difficult to meet. In order to improve the washing and wearing performance of cotton fabrics, the non-ironing crease-resistant finishing technology has become an indispensable finishing mode in the dyeing and finishing process of cotton fabrics.
Chinese patent CN201611115221.9 discloses a wool blended crease-resistant antibacterial western-style clothes fabric, which is blended by superfine polyester fibers, ramie fibers and wool, so that the fabric has the draping feeling of polyester, the good hand feeling of hemp fabric and the grade of the fabric is improved; the invention adopts a combination mode of vacuum enzyme treatment and polyurethane shaping to prevent the fabric from wrinkling, and has the defects of complex vacuum enzyme treatment process, high treatment cost and higher equipment requirement.
Disclosure of Invention
The invention aims to provide a crease-resistant non-ironing suit fabric aiming at the defects and shortcomings of the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
a crease-resistant non-ironing suit fabric is characterized by comprising a surface layer and an inner layer, wherein the surface layer and the inner layer are connected by adhesion; the surface layer is a mulberry silk blended fabric subjected to crease-resistant treatment, the inner layer is an adhesive/XLA fiber fabric, and the adhesive is a reinforced polyurethane adhesive.
The mulberry silk blended fabric subjected to crease-resistant treatment is prepared by the following method:
(1) performing low-pressure plasma treatment on the mulberry silk fiber for 4-5min under the conditions that the argon plasma gas pressure is 80-100Pa and the glow discharge power is 20-25W to obtain the mulberry silk fiber subjected to plasma treatment;
(2) and (2) mixing and spinning acrylic fibers and mulberry silk fibers subjected to plasma treatment in a mass ratio of 6:4-7:3, then warping, drafting and weaving, then placing into an anti-wrinkle solution for padding treatment for 3-5min, taking out, drying at 55-65 ℃, finally dyeing by using a dyeing agent, and drying at 60-75 ℃ to obtain the mulberry silk blended fabric subjected to anti-wrinkle treatment.
The preparation process of the viscose/XLA fiber fabric comprises the following steps: firstly, spinning the XLA fiber as a core yarn and the viscose fiber as an outer package into a core-spun yarn, and then warping, drafting and weaving to obtain the viscose/XLA fiber fabric.
The reinforced polyurethane adhesive is prepared from the following raw materials in parts by weight:
60-70 parts of isophorone diisocyanate, 100-120 parts of polycarbonate diol, 3-5 parts of chain extender diethylene glycol, 10-15 parts of tetrabutyl titanate, 0.8-2 parts of dimethyl carbonate, 6-8 parts of triethanolamine, 10-12 parts of stearic acid, 1-2 parts of dammar resin and 0.01-0.014 part of catalyst;
the preparation method comprises the following steps:
(1) heating and softening dammar resin, adding into ethanol with weight of 10-16 times of the dammar resin, and stirring at 60-65 deg.C for 10-20 min to obtain resin alcoholic solution;
(2) adding tetrabutyl titanate into the resin alcohol solution, uniformly stirring, adding water with the weight being 10-13 times of that of the mixture, stirring for 3-4 hours, carrying out suction filtration, washing a filter cake with water, and drying at normal temperature to obtain a resin sol;
(3) heating and melting stearic acid, mixing with resin sol and triethanolamine, stirring uniformly at the high temperature of 180 ℃ and 185 ℃, adding a catalyst, stirring and reacting for 6-7 hours, and cooling to normal temperature to obtain sol ester amine;
(4) mixing sol ester amine, isophorone diisocyanate and polycarbonate diol, feeding the mixture into a reaction kettle, introducing nitrogen, adjusting the temperature of the reaction kettle to be 75-80 ℃, keeping the temperature and stirring for 2-3 hours, adding chain extender diethylene glycol, reducing the temperature of the reaction kettle to be 55-60 ℃, keeping the temperature and reacting for 4-5 hours, discharging and cooling to obtain sol ester amine modified polyurethane;
(5) mixing sol ester amine modified polyurethane with dimethyl carbonate, feeding into a reaction kettle, introducing nitrogen, adjusting the temperature of the reaction kettle to 70-76 ℃, reacting for 40-46 hours, discharging and cooling to obtain the reinforced polyurethane adhesive.
The anti-wrinkle liquid is prepared from the following components in parts by mass:
adding 8-18 parts of urea, 0.01-0.05 part of cationic surfactant and 40-50 parts of water into a reactor, uniformly dissolving, then adding 2-5 parts of low-hydrogen silicone oil, uniformly dispersing and emulsifying at a high speed of 1200r/min, and heating to 50-70 ℃ for reaction for 1-2h to obtain a modified urea solution; adjusting the pH value to 5-6 and the temperature to 40-60 ℃, dropwise adding half of the modified urea solution into 20-25 parts of 40% glyoxal aqueous solution, adjusting the pH value to 4-5 after dropwise adding for 0.5-1h, dropwise adding the other half of the modified urea solution for 0.5-1h, and finally adjusting the pH value of the system to 4-5 to obtain the anti-wrinkle solution.
