Background
The wool can be traced back to the age of the neolithic apparatus by human beings, is spread from the middle asia to the mediterranean sea and other regions of the world, and gradually becomes a main textile raw material of the asia-europe. The wool fiber is soft and elastic, and can be used for making woollen goods, knitting wool, woollen blankets, shell fabrics, flocculus and other textiles. The wool product has the characteristics of plump hand feeling, good heat retention, comfortable wearing and the like. Sheep wool in the prior wool raw materials accounts for a large proportion in the textile raw materials, while sheep wool for home textile mainly takes coarse wool and semi-fine wool as main raw materials. Sheep wool is divided into 5 types of fine wool, semi-fine wool, long wool, hybrid wool, coarse wool and the like according to fineness and length. The Chinese sheep wool includes mainly Mongolian wool, Tibetan wool, Kazakh wool, etc. The main factors for evaluating the quality of the wool are fineness, curl, color, strength, weed content and the like.
Wool is an important raw material in textile industry, and has the advantages of good elasticity, strong hygroscopicity, good heat retention property and the like.

The process is simple, and the hyaluronic acid is added at the last time, so that the dosage of the hyaluronic acid is allowed to be reduced.
And (3) performance comparison:
after the super-soft wool modifier obtained in specific examples 1, 2 and 3 is used for wool, the obtained wool fibers have the characteristics of good glossiness and comfortable hand feeling, and the curling bulkiness of the fibers can be effectively improved. The super-soft modified wool obtained in the three examples can reach the following standard: the fineness is less than 30 um; the crimpness is more than 13/cm; bulk > 20cm3(ii) in terms of/g. Tests show that the combination property of the concrete example 1 is the best, and is a preferred scheme. The glycerol is added in the specific embodiment 2, the problem of breakage of wool in the treatment process can be effectively solved, but the modified wool is easily adhered to each other, and the glycerol is not easily removed in the later period. The specific embodiment 2 adjusts the proportion of the additive, and can effectively solve the problem that wool is easy to be mutually adhered. The specific embodiment 3 adopts the arrangement of low water and multiple additives, the proportion of the additives is large, the modification speed is high, but the bonding property with wool is slightly poor, and the specific embodiment 3 adjusts the proportion of the additives, so that the problem of poor bonding property can be effectively improved.
In all three embodiments, cooking wine can be used to replace water. The mutton smell on the wool is removed or reduced by cooking wine. In addition, in the specific example 2, the cooking wine has the effect of accelerating the dissolution of glycerol after replacing water. Or adding vinegar or wine into water, replacing water with vinegar or wine, and volatilizing vinegar or wine to remove or reduce the smell of mutton on wool. The method can also add de-odoring treatment between enzyme treatment and modification treatment, namely, in the enzyme treatment, the wool to be treated is firstly put into a cleaning box containing cooking wine, added with vinegar or wine water and soaked for 30-70 minutes, and then the modification treatment is carried out.
The wool may be subjected to an oxidation treatment or a reduction treatment prior to the enzymatic treatment of the wool. During oxidation treatment, the used oxidation treatment liquid contains potassium permanganate and sodium bicarbonate, the pH value is 3.5-5.0, the temperature of the oxidation treatment is 15-25 ℃, and the time is 20-60 min. The weight ratio of the oxidant to the wool in the oxidation treatment liquid is 2-6%, the weight ratio of the alkaline agent to the wool is 1-2%, the temperature is 15-25 ℃, and the time is 20-60 min. During reduction treatment, the used reduction treatment liquid contains sodium sulfite, the pH value is 7-8, the temperature of the reduction treatment is 30-60 ℃, and the time is 8-10 min. The weight ratio of the sodium sulfite to the wool in the reduction treatment liquid is 3-6%. Thereby utilizing oxidation treatment or reduction treatment to destroy special structures such as lipoid and cystine disulfide bonds contained on the surface of the wool fiber and in the cuticle, ensuring effective erosion and attack of enzyme, and solving the problem of unobvious treatment effect when only enzyme treatment is carried out. In addition, the wool fibers which are firstly oxidized or reduced and then treated by enzyme can be more convenient for the application of the super-soft wool modifier, thereby achieving the super-soft effect. The wool can be subjected to enzyme treatment by using a treatment solution containing enzyme, the enzyme in the treatment solution is preferably protease, the weight ratio of the protease to the wool is 0.2-1.0%, the treatment solution also contains sodium bicarbonate, the weight ratio of an alkaline agent to the wool is 0.2-1.0%, the pH value of the treatment solution is 7.5-8.5, the bath ratio is 1: 25. the enzyme treatment temperature is 45-50 deg.C, and the time is 30-50 min.
Preferably, the wool is treated by a one-bath three-step method through a wool washing machine, potassium permanganate is firstly oxidized, and the wool is taken out, washed by distilled water and dried for later use. Then sodium sulfite reduction treatment is carried out, and the sodium sulfite is taken out, washed by water at 60 ℃ and dried for standby. After redox treatment, the lipid and cystine disulfide bonds on the surface of wool fibers and in the stratum corneum were disrupted. Then carrying out enzyme treatment and modification treatment. After comprehensive treatment, the wool fiber has good smoothness and fullness. The degree of corrosion of the wool fiber scales is high, the decrement rate is increased, and the light specular reflection capacity is increased due to the filing of the wool fiber scales (the filing is the treatment result of the oxidation reduction and enzyme treatment processes on the surfaces of the wool fibers), so that the fabric is soft and improved, and meanwhile, the fabric can obtain lasting silk-like luster. Compared with the traditional chlorination treatment technology and the single enzyme treatment technology, the treated wool fiber has the advantages of greasy hand feeling, good elasticity and special glossiness. Under the prerequisite that does not influence the wool fibre powerful, its fineness can reduce about 2um after the super gentle modification treatment of wool fibre, improves wool fibre count, promotes the quality.
Because the step of modification treatment is added, at least one of wool brightening agent, hyaluronic acid, cationic waterborne polyurethane resin and suction and discharge softening agent exists on the surface of the wool obtained by the method. With caution, it is one of the bases of the products obtained by the method of the present invention to judge whether or not at least two of a wool brightener, hyaluronic acid, a cationic aqueous polyurethane resin, and a suction softening agent are present on the surface of wool. Of course, if wool brightener, hyaluronic acid, cationic waterborne polyurethane resin and suction and discharge softener exist at the same time, the wool brightener, hyaluronic acid, cationic waterborne polyurethane resin and suction and discharge softener can be further determined to be prepared by adopting the method. Meanwhile, due to the improvement of the process, the wool obtained by the method can reach the following standards: the fineness is less than 30 um; the crimpness is more than 13/cm; the bulk is more than 20cm 3/g. This criterion can also be taken as one of the bases for the products obtained by the process of the invention.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
