Description

A preparation method of fragrance light wool fabric with health care function

technical field

The invention relates to the technical field of fabrics, in particular to a method for preparing a fragrance light wool fabric with a health care function.

Background technique

With the continuous deepening of the functionalization of textiles, various multifunctional fabrics have emerged as the times require. The fragrance fabrics in the prior art are mainly based on microcapsule technology. By coating the aromatherapy essential oil in the microcapsules, the friction between the fabrics or the friction between the fabrics and human skin will cause the microcapsules to break and achieve slow release. The effect makes the fabric have a relatively long-lasting fragrance release effect. At the same time, the aromatherapy essential oil of the above-mentioned fragrance fabric can be absorbed through human breathing, and can achieve certain medicinal functions. Disclosed in 201110401213.1 is a kind of technical scheme of arranging frankincense microcapsules on the yarn surface and weaving them into fabrics. But above-mentioned essential oil microcapsule finishing gained fabric has the following technical defects: essential oil is mostly non-polar molecule, can not carry out miscibility with human body sweat or the water vapor that skin emits, and the essential oil on the fabric will not only adhere to the skin surface, but also to Escaping from the skin and the air, the absorption of essential oils on the skin is small; clothing made of fabrics needs to be washed and ironed, and the high temperature of cleaning operations and clothing ironing is the main way to destroy the microcapsules in the fabric, which will destroy the microcapsules. Sustained release effect. In addition, the diameter of wool fiber is small at room temperature, and the finishing solution cannot penetrate deeply into the cells, so the padding finishing effect is not good, and the hand feeling is poor.

Contents of the invention

The purpose of the present invention is to overcome the defects in the prior art, and provide a method for preparing a fragrance light wool fabric with health care function. The obtained wool fabric contains mastic resin with both medicinal value and fragrance, so that the fabric has a long-lasting Fragrance and health function.

In order to achieve the above-mentioned technical effects, the technical solution of the present invention is: a method for preparing a fragrance light wool fabric with a health care function, which is characterized in that it comprises the following steps:

S1: Configure merino wool and dralon superfine special-shaped acrylic fibers according to the weight ratio, spin the two fibers into high-count spinning yarns with a fineness of 520-580 metric counts, and then warp the high-count spinning yarns. The high-count spun yarn after warp is used as warp and weft to weave wool fabric;

S2: After-treatment, the fabric obtained in S1 is continuously boiled, de-dimensionalized, boiled, singed, washed, and sheared to obtain a semi-finished wool fabric;

S3: freezing treatment, placing the semi-finished wool fabric obtained in S2 at a temperature of -5~0°C for 20~30min;

S4: Anti-wrinkle finishing with frankincense microcapsules. The frozen wool fabric obtained in S3 is dipped in frankincense microcapsules anti-wrinkle finishing liquid, soaked twice, rolled twice, pre-baked, baked, washed and dried to make a health-care product. Fragrance light wool fabric finished products;

Among them, the frankincense microcapsule anti-wrinkle finishing solution in parts by weight includes: 5-13 parts of water-soluble polyurethane, 0.5-5 parts of softener, 0.01-1 part of surfactant, and nano-scale frankincense powder as the main capsule core component. 4-8 parts of frankincense microcapsules, 70 parts of water and citric acid, the pH value of the frankincense microcapsules anti-wrinkle finishing solution is 3-4.

By freezing the wool fabric, the moisture absorbed inside the fiber in the wool microstructure undergoes a phase change, that is, from liquid water to solid water, and with the increase in volume, the diameter of the wool fiber increases, and the internal voids increase, making finishing The liquid can be deeply impregnated into the internal space of wool, which can increase the contact area between polyurethane resin and wool fiber, improve the adhesion between the two, and improve the feel and wearability of wool fabric.

Frankincense powder is obtained by crushing frankincense resin at low temperature. Frankincense resin is the resin exuded from plant bark. It is a raw material for aromatherapy. Frankincense contains 60% to 70% resin, 27% to 35% gum, and 3% to 8% volatile oil. It has the effects of activating blood and promoting qi, dredging menstrual flow, relieving pain, reducing swelling and promoting granulation. It is brittle but softens after heating. After contact with water, the surface absorbs water and swells to become milky white, which is sticky. Frankincense acts as a capsule core microcapsule that adheres to the surface of the wool fabric. After the microcapsule is broken, the frankincense can be dissolved in sweat or water vapor evaporated from the skin surface. The viscosity of the aqueous solution can ensure that most of the swollen part adheres to the skin. surface, or embedded in the scales of wool fibers, which is different from the frankincense essential oil microcapsules in the prior art. After the frankincense essential oil microcapsules are broken, the amount of essential oil molecules that escape to the skin surface is small, that is, the amount that is finally absorbed by the skin is small . The volatile oil in frankincense adhered to the skin surface is absorbed by the human body through skin penetration or inhalation through the respiratory system, and the resin embedded in the scales of wool fibers helps to improve the feel and wearing performance of wool fabrics in dry environments.

The texture of frankincense resin is relatively hard at room temperature, and its texture becomes soft at high temperature. Therefore, after the microcapsule wall ruptures at room temperature, the remaining capsule wall is still attached to the surface of the capsule core, and the water vapor slowly swells the exposed capsule core until the microcapsule wall is broken. The core is consumed; when the fabric is ironed at high temperature, the microcapsules can be properly deformed to buffer the pressure, ensure the damage of the microcapsules by high temperature ironing, and prolong the fragrance release time of the fabric. In addition, the frankincense microcapsules after roasting and cooling undergo the change of capsule core form solid-liquid-solid, and are in a spherical or spherical shape with stable structure.

The preferred technical scheme is that the frankincense microcapsule is a double-wall material microcapsule, the main component of the inner wall material in contact with the capsule core is insect wax and/or beeswax, and the main component of the outer wall material positioned at the outer surface of the frankincense microcapsule is Sodium Alginate and/or Chitosan. The free fatty alcohol in the insect wax and beeswax of the inner wall material and the boswellic acid in the frankincense undergo esterification and cross-linking, which effectively coats the capsule core material to form hydrophobic microcapsules. The function of the outer wall material is to Under the condition of heating and ironing the fabric, ensure that the capsule wall does not melt.

In order to ensure the bulkiness, moisture permeability, warmth retention and wearability of the fabric, the preferred technical solution is that the weight of merino wool in the wool fabric obtained in S1 is 50-70%.

The preferred technical solution is that the frankincense microcapsule anti-wrinkle finishing solution also includes 0.05-5 parts of frankincense micropowder, and the average particle diameter of the frankincense micropowder is not greater than 100 μm. Add frankincense micro-powder to frankincense microcapsule anti-wrinkle finishing solution. After finishing, the resin and gum in frankincense are dispersed and mixed in polyurethane, which can give the fabric a strong initial fragrance and health care function. If the average particle size of frankincense micro-powder is too large Facilitate its rapid dissolution in aqueous solution.

The preferred technical solution is that the preparation method of the frankincense microcapsules anti-wrinkle finishing solution is as follows: add the frankincense micropowder to part of the water, disperse with high speed shear, heat to 90~95°C and keep it for 2~5 minutes, continue to disperse with high speed shear and cool to room temperature to obtain Anti-wrinkle finishing solution A mixed solution; add water-soluble polyurethane, softener, surfactant, and frankincense microcapsules with frankincense as the capsule core to the remaining water in sequence, stir and mix well to obtain anti-wrinkle finishing solution B mixed solution, and put anti-wrinkle finishing solution The mixed solution of solution A and the mixed solution of anti-wrinkle finishing solution B are mixed and stirred evenly, and the frankincense microcapsule anti-wrinkle finishing solution is prepared. The above preparation method can disperse the frankincense component in the finishing liquid more uniformly and form a uniform dispersion liquid.

The preferred technical solution is that the temperature of the frankincense microcapsule anti-wrinkle finishing solution in S4 is 5-10°C, the soaking time is 4-10 minutes, and the bath ratio is 1: (15-25). The lower padding temperature of the anti-wrinkle finishing solution can maintain the larger internal voids of the wool fiber after freezing treatment, and ensure the penetration of the finishing solution.

Higher baking temperature will cause the capsule wall of microcapsules to melt, sodium alginate and chitosan have higher melting points, and the melting of insect wax and beeswax as the inner wall material will be more effective for the formation of frankincense inside The coating helps to enhance the overall strength of the microcapsules. The preferred technical solution is that the pre-baking temperature in S4 is 50-60 °C, and the pre-baking time is 2-5 minutes; the baking temperature is 95-115 °C. The baking time is 5~13min.

The preferred technical solution is that the capsule core of the frankincense microcapsules also includes nano-scale sepiolite powder, and the weight ratio of the nano-scale sepiolite powder to the frankincense in the capsule core is 1: (2~3). Nano-scale sepiolite powder can absorb the peculiar smell of the wearer's body surface, ensuring a more complete fragrance of frankincense.

The preferred technical solution is that the softener is at least one selected from aminated polysiloxanes containing polyether groups and quaternary ammonium cationic polyurethane-based polyether block hydrophilic silicone softeners. The introduction of polyether groups in the molecular structure makes the amino polysilicone softener hydrophilic and reduces yellowing. The steric hindrance between the softener molecules is particularly small, and the main chain of the molecule is supple, which can endow the wool fabric with a unique " "Soft and waxy" soft style, which can improve the hard feel of wool fabrics due to the adhesion of microcapsules without affecting the hydrophilicity of wool fabrics.

The preferred technical solution is that the surfactant is a diquaternary ammonium salt type gemini surfactant linked by a rigid linking group -CH ₂ -. The double quaternary ammonium salt type gemini surfactant has a higher CMC value, which can reduce the surface tension of the finishing solution and make it penetrate more deeply.

Advantage and beneficial effect of the present invention are:

In the present invention, the wool fabric is subjected to freezing treatment in advance, and then the frankincense microcapsule anti-wrinkle finishing liquid is applied to pad and roll finishing. After the freezing treatment, the internal fiber internal space of the wool fabric increases, and the anti-wrinkle finishing liquid deeply wets to the internal space of the fiber, and the polyurethane resin The adhesion between the frankincense and the wool fabric is enhanced, and the frankincense is organized into the wool fabric in the form of microcapsules.
