Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a preparation method of a fragrant circle check overcoat woolen.

In order to achieve the purpose, the invention provides a preparation method of a ring check costume tweed, which comprises the steps of preparing raw materials, namely preparing wool fibers, viscose fibers, nylon fibers and polyester fibers according to the weight ratio of 7: 1: 1:1 into wool yarns and loop yarns, weaving the wool yarns and the loop yarns into loop check costuming grey cloth by adopting a rapier loom, and then carrying out fulling, tweeng, dewatering, drying, decating, burdening, shearing, aromatic treatment and drying on the grey cloth to prepare the finished costuming woolen product. The fabric prepared by the method has the patterns of loop yarn and plover check, is elegant in pattern, elegant in style, fine and smooth in hand feeling, stiff, smooth and elastic, and has good heat retention and fragrance.

The preferred technical scheme is that the aromatic treatment comprises the steps of placing sheared grey cloth at the temperature of-5-0 ℃ for standing for 20-30min, then soaking the grey cloth in aromatic crease-resistant finishing liquid, soaking and rolling the grey cloth twice, drying the grey cloth, washing the dried grey cloth with water and drying the washed grey cloth to obtain a finished aromatic overcoat woolen product; the aromatic crease-resistant finishing liquid comprises the following components in parts by weight: 15-20 parts of water-soluble polyurethane, 0.5-5 parts of a softening agent, 0.01-1 part of a surfactant, 4-8 parts of a microcapsule taking thermosensitive slow-release particles as capsule cores, 70 parts of water and citric acid, wherein the pH value of the aromatic anti-wrinkle finishing liquid is 3-4; the preparation method of the thermosensitive sustained-release particles comprises the following steps of a, pulping: mixing the perfume plant material and deionized water or homogenate according to the weight ratio of 1: weighing 2-5 parts, placing into a homogenizer, pulping by the homogenizer, and filtering by using a screen with the aperture smaller than 200 meshes to remove larger fibrous substances; b, breaking the wall: treating the slurry by using an ultrasonic cell crusher to enable plant cell walls and cell membranes in the slurry to crack; c, freeze-drying: and (3) putting the treated slurry into a vacuum freeze dryer for freeze-drying, wherein the pre-freezing temperature is not more than-20 ℃, the freeze-drying temperature is not more than-10 ℃, the water content of the dried material is 7-9%, and the heat-sensitive slow-release particles are obtained after freeze-drying. The microcapsules directly embed essential oil, when the fabric is worn, due to the effects of friction, extrusion, beating and rubbing, the microcapsule base material is broken, substances such as fragrant essential oil and the like are completely released, uneven fragrant sensory feeling of 'thick front and thin back' or 'thin front and thick back' is easily formed, in addition, the diameter of wool fibers is small at normal temperature, finishing liquid cannot be deeply diffused into the fibers, the padding finishing effect is poor, and the hand feeling is poor. By freezing the wool fabric, the moisture adsorbed inside the fibers in the microstructure of the wool is changed into solid ice crystals from a liquid state, the diameters of the wool fibers are increased along with the increase of the volume, the internal gaps are increased, the ice crystals inside the wool fibers are melted after the normal temperature is recovered, but the expanded internal gaps are not retracted, so that the finishing liquid can be deeply soaked into the internal gaps of the wool, the contact area between polyurethane and the wool fibers can be increased, the adhesion between the polyurethane and the wool fibers is improved, and the hand feeling and the wearability of the wool fabric are improved; processing plant cells by using a low-frequency ultrasonic wall breaking technology to enable the cell walls to have partial cracks instead of complete removal, expanding the cracks on the cell walls to form cracks due to the principle of thermal expansion and cold contraction when the temperature is increased, releasing fragrant substances, closing the cracks on the cell walls when the temperature is reduced, and stopping or slowly releasing the fragrant substances; the perfume plant material is dried by using a vacuum freeze drying technology, and through low-temperature freezing and temperature rise, substances in membranes of plant cells are frozen to form ice crystals, so that the volume is expanded, the cell membranes are burst or punctured, the loss of original volatile fragrance is basically avoided in the drying process of the material, and the cell walls of natural plants with the fragrance substance slow-release capability are not damaged; the slurry with cell wall cracks after ultrasonic crushing and freezing treatment is embedded in the microcapsules, the fragrance substance has two layers of protection of cell walls and the outer walls of the microcapsules, the fragrance slow-release time is longer, and the fragrance is more durable.

According to a further preferable technical scheme, the aromatic anti-wrinkle finishing liquid further comprises 0.05-5 parts of plant essential oil. After the fabric is finished by adding the aromatic crease-resistant finishing liquid containing the plant essential oil, the plant essential oil can endow the fabric with thick initial aroma before the fabric is not used or clothes and home textile products made of the fabric are not contacted with a human body for use in a large area.

In order to ensure that the capsule wall is not melted as much as possible under the condition that the fabric is heated and ironed, prevent the perfume substances embedded in the capsule from being directly exposed and increase the perfume retention time, the further preferable technical scheme is that the main component of the microcapsule outer wall material is potassium alginate and/or chitosan.

In order to ensure that the cell walls of the plant cells with the aromatic substances are not completely broken, only partial cracks are generated, and the aromatic substances in the cells cannot be completely exposed, the more preferable technical scheme is that the frequency of the ultrasonic cell crusher is 20-25KHZ, and the ultrasonic time is 5-10 min.

Further preferably, the softening agent is at least one selected from amino polysiloxane containing polyether groups and quaternary ammonium type cationic polyurethane polyether block hydrophilic silicone softening agent. The introduction of polyether groups in the molecular structure enables the amino polyorganosiloxane softener to have hydrophilicity and reduce yellowing, the steric hindrance between molecules of the softener is very small, the main chain of the molecule is soft, the wool fabric can be endowed with unique soft and glutinous soft style, and the harder hand feeling of the wool fabric due to the adhesion of microcapsules can be improved without affecting the hydrophilicity of the wool fabric.

Further preferably, the surfactant is composed of a rigid linking group-CH₂-a linked gemini surfactant of the bis-quaternary ammonium salt type. The double quaternary ammonium salt type gemini surfactant has higher CMC value, can reduce the surface tension of the finishing liquid and can achieve the aim of deeper penetration.

The further preferred technical scheme is that the temperature of the aromatic crease-resistant finishing liquid for aromatic crease-resistant finishing is 5-10 ℃, the dipping time of the semi-finished product of the wool fabric is 10-15min, and the bath ratio is 1: (10-15). The lower padding temperature of the aromatic crease-resistant finishing liquid can maintain larger internal gaps of the wool fibers after freezing treatment, and the deep penetration of the finishing liquid is ensured.

The higher baking temperature can lead the capsule wall of the microcapsule to melt, in order to avoid the early rupture of the capsule wall of the microcapsule, the aromatic substances in the capsule volatilize prematurely, thereby the slow-release aroma-retaining time is shortened when the product reaches the hands of consumers, and the further preferable technical proposal is that the baking temperature in S2 is 80-95 ℃ and the baking time is 15-20 min.

The invention has the advantages and beneficial effects that: the fabric produced by the preparation method has the patterns of loop yarn and chiffon check, is elegant in pattern, elegant in style, exquisite and smooth in hand feeling, stiff, smooth and elastic, and has good heat retention and fragrance which is continuously and slowly released. Through freezing the wool fabric, the internal gaps of the wool fibers are enlarged, so that the finishing liquor can be deeply impregnated into the internal gaps of the wool, the contact area between the polyurethane resin and the wool fibers is increased, the adhesion between the polyurethane resin and the wool fibers is improved, and the hand feeling and the wearability of the wool fabric are improved. The thermosensitive plant fragrance slow-release particle microcapsule prepared by a low-frequency ultrasonic wall-breaking technology is used as a perfuming component in the fragrant anti-wrinkle finishing liquid, so that the effect of uniformly releasing fragrance substances along with the change of temperature is achieved, and the fragrance treatment method enables the fabric to have longer fragrance retention time and uniformly release along with the change of temperature on the premise of keeping the original fragrance characteristics of natural plants.
