Description

Technical Field

[0001] The present invention belongs to the technical field of chemical auxiliaries, and particularly relates to a flax health care enzyme preparation, a preparation method thereof, and an application thereof. Background Art

[0002] Flax is a bast fiber crop, and its main components are cellulose, hemicellulose, lignin, pectin, fat, and wax. The directly machine-spun preliminary processed flax fibers are extremely easy to break, cause fiber dropping, and increase the short fiber rate. At the same time, due to static electricity and relatively large fiber stiffness, hairiness and broken ends increase, and the sliver thickness is uneven, reducing the yarn quality. Therefore, it is necessary to carry out health care on it.

[0003] The health care is mainly to humidify and maintain the fibers and give a certain amount of emulsion to the fibers. The common emulsion is generally prepared with 1% emulsifying oil, 3% penetrant, and 96% water, or a special flax humidifying agent can also be used. Then, the long flax and short flax are humidified layer by layer using manual or high-pressure spraying equipment. After the fibers are humidified, the oil and water obtained by each part of the fibers are uneven. To make the emulsion fully penetrate into the fibers, improve the combing long flax rate of the comber, and reduce fiber dropping, maintenance is required. Generally, the flax pile is covered with nylon cloth and placed for no less than 24 hours. The stacking time in summer is generally 2 - 3 days, and in winter, due to low temperature, the stacking time is 3 - 7 days, or even longer.

[0004] At present, the penetrants on the market are difficult to simultaneously have good permeability and softness. Several different auxiliaries must be used in combination. However, the above combination is likely to cause mutual influence among different auxiliaries, damage the system environment suitable for each, and affect the health care effect. In addition, many units do not have supporting humidifying and heat preservation equipment, cannot provide a good health care environment, cause great impact on continuous production, and seriously affect the quality of flax sliver. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems raised in the above background, and provide a flax health care enzyme preparation, which has extremely high permeability, can give good softness to flax, can obtain an ideal health care effect, greatly shortens the health care time, improves production efficiency, and lays a good foundation for continuous carding and spinning.

[0006] The technical solution adopted by the present invention to solve the above problems is as follows: A flax health care enzyme preparation, comprising the following raw materials in parts by weight:

[0007] Penetrant JFC-S 15 - 20 parts

[0008] Iso-decyl alcohol polyoxyethylene ether 10 - 15 parts

[0009] Castor oil polyoxyethylene ether 3 - 5 parts

[0010] 1 - 3 parts of lauramidopropyl betaine

[0011] 3 - 5 parts of diethylene glycol monobutyl ether

[0012] 3 - 5 parts of non - ionic surfactant

[0013] 3 - 5 parts of dimethyl silicone oil

[0014] 10 - 13 parts of silicone emulsion

[0015] 3 - 5 parts of Cellusoft enzyme

[0016] 24 - 49 parts of pure water.

[0017] Further, the Cellusoft enzyme is Cellusoft Neupolish 8000 L, and optionally, it can be Cellusoft Neupolish 8000 L produced by Novozymes.

[0018] Further, the non - ionic surfactant is Peregal O.

[0019] Further, the silicone emulsion is silicone emulsion T533 produced by Wacker.

[0020] Another object of the present invention is to provide a preparation method of a flax health - care enzyme preparation, including the following steps:

[0021] (1) Heat pure water to 40 - 50 °C, add isomeric decanol polyoxyethylene ether, castor oil polyoxyethylene ether, lauramidopropyl betaine, and non - ionic surfactant, heat to 55 - 65 °C, and stir for 40 - 60 minutes;

[0022] (2) Add penetrant JFC - S, diethylene glycol monobutyl ether, and dimethyl silicone oil, and stir for 30 - 50 minutes;

[0023] (3) Cool to 30 - 40 °C, add silicone emulsion and Cellusoft enzyme, and stir for another 1 - 2 hours to obtain the product.

[0024] Another object of the present invention is to provide an application of the above - mentioned flax health - care enzyme preparation in the flax health - care process.

[0025] Compared with the prior art, the advantages of the present invention are as follows:

[0026] The flax health care enzyme preparation prepared by the present invention has strong permeability and can accelerate the penetration of the emulsion into the flax fiber during the health care process. Among them, the fiber softening enzyme in the formula causes cracks on the fiber surface, partially degrades the cellulose macromolecule, increases the specific surface area of the fiber, and increases the proportion of the amorphous part. At this time, the amino-modified silicone softener is more likely to cross-link with the hydroxyl groups on the cellulose to form a softener molecular film on the fiber surface, making up for the damaged strength while quickly penetrating. Moreover, this product does not contain phosphorus, APEO and formaldehyde, and is a green environmental protection product. Embodiment

[0046] Comparative Example 1:

[0047] A flax curing enzyme preparation, by weight, comprises the following components:

[0048] 20 parts of penetrant JFC-S, 15 parts of isomeric decanol polyoxyethylene ether, 5 parts of castor oil polyoxyethylene ether, 3 parts of lauramidopropyl betaine, 5 parts of diethylene glycol monobutyl ether, 5 parts of Peregal O, 5 parts of dimethyl silicone oil, 13 parts of silicone emulsion T533 (from Wacker Chemie AG), 5 parts of Cellusoft Neupolish 8000 L (from Novozymes A / S), and 24 parts of pure water.

[0052] Comparative Example 2:

[0053] Use a commercially available flax curing emulsion as a comparative example. The commercially available flax curing emulsion, by weight, comprises the following components: 6 parts of polyurethane-modified block silicone oil emulsion, 6 parts of hydrophilic soft oil essence, 2 parts of sorbitol, 46 parts of hydrophilic block silicone oil, 30 parts of nonionic fatty alcohol polyoxyethylene ether, and 10 parts of pure water

[0054] The preparation method of the flax curing enzyme preparation comprises the following steps:

[0055] At room temperature, first add the polyurethane-modified block silicone oil emulsion and hydrophilic soft oil essence, stir for 20 minutes until uniform, then add sorbitol, hydrophilic block silicone oil, nonionic fatty alcohol polyoxyethylene ether, and pure water and stir for another 40 minutes before discharging.

[0056] Comparative Example 3

[0057] Compared with Example 1, the difference is only that: no cellulase Cellusoft Neupolish 8000 L is added.

[0058] Next, the properties of the final prepared auxiliaries in the examples and comparative examples were tested:

[0059] The prepared flax health care enzyme preparation was prepared into a working solution to be tested according to the ratio of enzyme preparation: water = 3:97 and reserved.

[0060] Permeability

[0061] Using the canvas sedimentation method, a standard round canvas piece with a diameter of 35 mm was placed in 200 mL of the working solution to be tested. The working solution to be tested was at 25 °C. The stopwatch was used to record the time required for the canvas piece to sink from the surface of the solution to the bottom of the beaker. The above steps were repeated 5 times and the average value was taken. The smaller the value, the faster the wetting and sedimentation, indicating better permeability.

[0062] Temperature stability

[0063] 100 mL of the working solution to be tested was placed at 0 °C, 5 °C, 10 °C, 20 °C, 30 °C, and 40 °C for 1 hour respectively. If the solution does not freeze at low temperature and remains clear, transparent and uniformly dispersed at high temperature, it indicates good temperature stability of the solution.

[0064] Compatibility stability

[0065] The working solution to be tested and the aqueous solution of flaxseed oil (flaxseed oil: water = 3:97) were compounded into a 200 mL emulsion according to a ratio of 1:1 and placed in an environment at 25 °C for observation. The prepared emulsion should have no abnormalities for at least 72 hours. The faster the layering and oil floating, the worse the compatibility.

[0066] Hand feeling

[0067] Six portions of 20 grams of flax fibers for health care were weighed and marked. The flax health care enzyme preparations prepared in the examples and comparative examples were prepared into 200 mL of working solutions to be tested and corresponding numbers were marked. The weighed flax fibers were soaked for 20 minutes under the same temperature conditions according to the corresponding numbers, taken out, dehydrated, dried at 40 °C and then naturally cooled. Five professional persons were asked to distinguish the hand feeling of the fibers with their eyes closed, mainly considering the comprehensive hand feeling of softness, smoothness and fluffiness, which were divided into five levels: 1, 2, 3, 4, and 5. The larger the value, the better the corresponding hand feeling.

[0068]

[0069] From the above table, the flax health care enzyme preparation prepared by the present invention has good permeability, good temperature resistance, good compatibility when used in combination with flaxseed oil, does not layer within 72 hours, and has excellent hand feeling.

[0070] The raw material ratio of Comparative Example 1 is within the scope of the present invention, but the feeding order during preparation is inconsistent with the method of the present invention. It can be seen from the experimental results that both the permeability and temperature stability are relatively good, but for the compatibility stability, delamination occurs within 72 hours.

[0071] The raw material formula used in Comparative Example 2 is different from that of the present invention, and its permeability is far worse than that of the examples.

[0072] In Comparative Example 3, no cellulase is added, and its permeability, hand feeling and compatibility stability are all worse than those of Example 1.

[0073] It can be seen that the flax health care enzyme preparation of the present invention has strong permeability, and the cellulase has a good penetration enhancing effect. When used in combination with linseed oil, it can penetrate into the interior of flax fibers better and faster, greatly shortening the health care time and improving the production efficiency. The added silicone oil component can provide a good soft and smooth hand feeling, providing favorable conditions for subsequent processes such as flax opening in the health care. Moreover, the present invention is convenient to use, easy to dilute and dissolve, does not contain alkylphenol polyoxyethylene ether, does not contain phosphate ester, has good biodegradability, and is green and environmentally friendly.

[0074] In addition to the above examples, the present invention also includes other embodiments. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present invention.
