Description
Technical Field
The invention relates to the field of textiles, in particular to an ultra-soft antibacterial dandelion polyester fiber blended flocking fabric and a preparation method thereof.
Background
With the continuous improvement of living standard of people, people pursue self health and living environment more and more, and the fabric of clothes is taken as next-to-skin fabric, people have higher requirements on the health of the fabric, and the fabric has better special properties such as air permeability, antibacterial and bacteriostatic properties, softness and the like besides the non-toxic action on human bodies. In recent years, due to formaldehyde-containing substances in textiles, people gradually turn the focus of raw materials of the textiles to natural, environment-friendly, ecological and renewable raw materials such as bamboo fibers, cotton fibers and the like, and currently, researches on the bamboo fibers and the cotton fibers are relatively more, while other plant fibers are few and less, and the other plant fibers cannot be applied to the textile fabrics in a large amount.
The dandelion contains a plurality of chemical components, has good effects of promoting lactation, resisting bacteria, benefiting gallbladder and resisting tumors, and is a health-care plant used as both medicine and food. From the perspective of resource development and utilization, the dandelion fiber is a novel fiber material which is not developed and utilized yet, the flocking fabric is deeply loved by people due to the unique style of strong stereoscopic impression, soft hand feeling, luxury and high-price, the dandelion and other fiber blended fabric is applied to the flocking fabric, the green consumption of China can be promoted, the development of the textile industry is promoted, but the flocking fabric has the problems of hair falling and hair falling due to the special surface effect, after washing, the fluff is disordered and has poor softness, and the fabric style is seriously influenced.
How to solve the problems that the existing flocking fabric has insufficient flexibility, insufficient antibacterial property and easy pilling is the key of the invention, so that an ultra-soft antibacterial dandelion polyester fiber blended flocking fabric and a preparation method thereof are urgently needed to solve the problems.
Disclosure of Invention
In order to overcome the technical problems, the invention aims to provide an ultra-soft antibacterial dandelion polyester fiber blended flocking fabric and a preparation method thereof, wherein the ultra-soft antibacterial dandelion polyester fiber blended flocking fabric comprises the following steps: the blended fiber is evenly mixed with the dandelion fiber and the polyester fiber to obtain the blended fiber, the blended fiber is spun to form yarn to obtain blended yarn, the blended yarn is formed through spinning, blended flocking fabric is obtained, the blended flocking fabric is put into the reinforcing modification liquid for impregnation, the mode of twice impregnation and twice rolling is adopted for arrangement, the super-soft antibacterial dandelion polyester fiber blended flocking fabric is obtained, and the problems that the existing flocking fabric is insufficient in softness, the antibacterial property is not high enough and pilling is easy are solved.
The purpose of the invention can be realized by the following technical scheme:
the preparation method of the super-soft antibacterial dandelion polyester fiber blended flocking fabric comprises the following steps:
the method comprises the following steps: weighing 20-50 parts of dandelion fiber and 50-75 parts of polyester fiber according to parts by weight for later use;
step two: uniformly mixing the dandelion fibers and the polyester fibers to obtain mixed fibers, and spinning the mixed fibers to form yarns to obtain blended yarns;
step three: spinning and forming the blended yarns to obtain a blended flocking fabric;
step four: weighing 5-15 parts of reinforcing modifier, 0.5-1.5 parts of emulsifier and 100 parts of deionized water according to parts by weight for later use;
step five: adding the reinforced modifier and the emulsifier into deionized water, and shearing and dispersing for 1-2h under the condition that the stirring speed is 5000-;
step six: blending flocking fabric according to a bath ratio of 1: 30, soaking in a reinforced modified solution for 1-1.5h, finishing in a two-soaking and two-rolling mode, controlling the rolling residual rate to be 75-85%, then pre-drying for 90-150s at the temperature of 75-90 ℃, and then baking for 60-90s at the temperature of 110-135 ℃ to obtain the super-soft antibacterial dandelion polyester fiber blended flocking fabric.
As a further scheme of the invention: the emulsifier is one or a mixture of two of emulsifier AEO-4 and emulsifier AEO-9 according to equal mass ratio.
As a further scheme of the invention: the preparation method of the reinforced modifier comprises the following steps:
a1: adding a sodium hydroxide solution into a four-neck flask provided with a stirrer, a thermometer, a reflux condenser tube and a constant-pressure dropping funnel, stirring and simultaneously dropping diethylamine and allyl chloride under the conditions that the temperature is 43-47 ℃ and the stirring rate is 250-;
the reaction principle is as follows:
under the alkaline condition, diethylamine is used for reacting with allyl chloride, diethylamine is a strong nucleophilic substance, is easy to attack allyl chloride and carries out nucleophilic substitution reaction with chlorine atoms on the allyl chloride, and thus amine organic matters containing alkenyl are generated, namely an intermediate 1;
a2: adding the intermediate 1 and tetramethyldisiloxane into a three-neck flask provided with a stirrer, a thermometer and a gas-guide tube, introducing nitrogen for protection, heating to 40-45 ℃ while stirring under the condition that the stirring rate is 250-350r/min, controlling the heating rate to be 0.8-1.6 ℃/min, then adding chloroplatinic acid hexahydrate, continuously stirring for reaction for 2-3h, cooling a reaction product to room temperature after the reaction is finished, carrying out vacuum filtration, and distilling the filtrate under reduced pressure to remove low-boiling-point substances with the temperature of 71-73 ℃ and the pressure of 15kPa to obtain an intermediate 2;
the reaction principle is as follows:
taking chloroplatinic acid hexahydrate as a catalyst, reacting the intermediate 1 with tetramethyldisiloxane, and carrying out hydrosilylation reaction on alkenyl on the intermediate 1 and tetramethyldisiloxane Si-H to obtain an intermediate 2 with a main chain of Si-O bond and a tertiary amine group at the end;
a3: adding the intermediate 2, chloropropanol and absolute ethyl alcohol into a three-neck flask provided with a stirrer, a thermometer, a reflux condenser tube and a gas guide tube, introducing nitrogen for protection, stirring and reacting for 15-20h under the conditions that the temperature is 80-85 ℃ and the stirring rate is 350-450r/min, after the reaction is finished, carrying out reduced pressure distillation on the reaction for 1-1.5h under the conditions that the removal temperature is 40-43 ℃ and the pressure is 0.08-0.1MPa, washing the distillation product for 2-3 times by using petroleum ether and anhydrous ether in sequence, and then placing the product in a vacuum drying oven to be dried to constant weight to obtain an intermediate 3;
