Description

Chlorine-free shrink-proof treatment equipment for wool raw material and product

Technical Field

The utility model relates to a wool product processing field specifically relates to an equipment that is used for chlorine-free shrink-proof of wool raw materials and goods to handle.

Background

Wool is an important raw material in the textile industry and has many excellent characteristics, such as good elasticity, strong hygroscopicity, less staining tendency, good heat retention and soft luster. Wool is a natural protein fiber, a layer of scale layers which are mainly composed of keratin and are overlapped with each other like fish scales is attached to the surface of the natural protein fiber, and due to different friction coefficients in the forward and reverse scale directions, the wool fibers are mutually interpenetrated, entangled, interwoven and felted under the repeated action of external force to generate fulling. Although the fulling enables the wool fabric to have the effects of beautiful appearance, thick and soft hand feeling and good heat preservation performance, the size of the wool fabric is easy to shrink and deform in the washing process. Therefore, in order to improve the anti-felting property of wool textiles and the dimensional stability of wool textile products and enable the products to achieve the effect of machine washing, the surface scale modification treatment of wool fibers is needed from the source.

At present, the main methods for modifying and shrink-proofing wool surface scales comprise: chlorination, overlay, protease, etc. Most widely, chlorination shrink-proofing treatment organic halide AOX (which is an absorbable organic halide) generated during chlorination treatment severely pollutes the environment.

Chinese patent CN201010605809.9 reports that potassium permanganate and DCCA are added into clean water in the form of catalyst, and then chlorine gas is introduced to carry out shrink-proof and scale-stripping process on wool tops, and the method reduces the chlorine gas consumption by 30% on the original basis. Although the method is an improvement on the traditional chlorination method, the method still uses chlorine gas and still causes serious environmental pollution. The covering method is to deposit a layer of resin film on the surface of wool to fill the scale and gap on the surface of wool so as to smooth the surface of wool and further reduce the surface friction effect of fiber. Although this treatment improves the felting properties of the fibers to some extent, it seriously affects the hand of the wool fabric and is not always durable enough. The protease method is to use the hydrolysis of the peptide bond of macromolecule on the surface of wool fiber by protease to partially dissolve the scales and cell membrane compound of wool, so as to achieve the purpose of partially or completely removing the scales. The treatment method has the advantages of mild treatment conditions, energy conservation, pollution reduction and the like, and is an environment-friendly wool anti-felting finishing method. However, the shrink-proof effect of wool treated with protease alone has not yet met the practical need, and therefore, in many cases, wool is subjected to a biological modification treatment with protease, and the wool is subjected to a pretreatment (for example, a pre-oxidation treatment with a strong oxidizing agent such as potassium permanganate, or a pretreatment treatment with a chloride solvent). The pretreatment methods have the defects of overlong treatment time, easy inactivation of enzyme, difficult control of treatment conditions and the like.

Furthermore, although there have been researchers attempting to develop a chlorine-free shrink-proofing process for wool materials, there are the following disadvantages: (a) the treatment time is long (the treatment quality cannot be reduced to be within 30 minutes); (b) the treatment capacity is limited, and the method is not suitable for industrial application; (c) the treatment quality has large fluctuation, and wool processing products with uniform treatment effect are difficult to obtain. Therefore, in the main wool material processing countries such as China, no chlorine-free shrink-proof treatment process is adopted to process wool materials in actual production at present.

In conclusion, there is an urgent need in the art to develop a wool shrink-proof treatment apparatus and process which are environment-friendly, simple and controllable in process, durable in shrink-proof effect, high (or rapid) in treatment efficiency, and suitable for mass production.

After the treatment, the wool product not only has good shrink-proof performance, but also has greatly improved wetting and penetrating performance, and the dripping water diffusion time (according to GB/T21655.1-2008) is improved to be less than or equal to 10 seconds from more than or equal to 10 minutes before the treatment.

Comparative example 1

Treatment by soaking

The descaling shrink-proof treatment is carried out by adopting a conventional soaking method, and the method comprises the following steps:

the wool tops (70 pieces, 20g) were soaked in the soaking solution sufficiently for 20 minutes or 60 minutes (50 ℃). After the soaking treatment, the post-treatment was carried out by a conventional method (similar to example 1) including 3 times of water washing, then enzyme inactivation treatment and softening treatment, and finally dehydration and drying.

Wherein, the formula of the soaking treatment liquid is as follows: 3g/L of alkaline protease (alkali protease), 1g/L of nonionic surfactant JFC (pH 8.5) and water as a solvent.

The results show that when the soaking time was 20 minutes, the descaling of part of the wool was insufficient. When the soaking time is 60 minutes, the desquamation effect of the wool is basically uniform, but the condition that the desquamation of the wool is insufficient exists in a small amount of wool. This indicates that the soaking process is not suitable for mass production due to long time consumption and non-uniform treatment effect.

Comparative example 2

Soaking-steaming treatment

The comparative example uses a conventional batch type, and the descaling and shrink-proof treatment is carried out by a soaking-steaming method. The method comprises the following steps:

wool tops (70 counts, 20g) were thoroughly soaked in a soaking solution (50 ℃, mangle ratio 120%), presoaked for about 1 minute, and then steamed (50 ℃) in a steaming box for 25 minutes, during which steaming solution (same composition as the soaking solution) was replenished at 5, 10, 15 and 20 minutes. The soak-steam treatment took 26 minutes.

After the soaking-steaming treatment, the post-treatment was carried out by a conventional method (similar to example 1) including 3 times of water washing, then enzyme inactivation treatment and softening treatment, and finally dehydration and drying.

The formulation of the soak solution was similar to that of the soak solution of example 1, but the soak solution did not contain tris (3-hydroxypropyl) phosphine. Namely, the formula is as follows: 3g/L of alkaline protease (alkal i protease) and 3g/L of nonionic surfactant JFC1 g/L.

As a result:

after the wool is subjected to the shrink-proof treatment, the sharp corners of the scales on the surface of the wool are basically all cut off. But the uniformity is poor, wherein the surface scales of the thinner wool are fuzzy, and the thicker wool scale layer is very thin, which shows that the treatment process has better stripping effect on the fine wool scales than on the thicker wool.

The strength of the treated fiber is 10.34cN, and the strength retention rate is 83.25%; the elongation was 32.30% and the elongation retention was 64.77%. This shows that the wool treated by this process can meet the requirements of shrinkproof, the loss of breaking strength is in acceptable range, but the loss of elongation is relatively large.

Furthermore, the whole soaking-steaming treatment took as long as 26 minutes, and the treatment effect was much inferior to examples 1 to 5. On the contrary, the total time of the multiple padding in examples 1 to 5 of the present invention was very short (5 minutes or less, preferably 3 minutes or less), and the descaling effect was more uniform and the shrinkproof property was more excellent.

The utility model has the outstanding characteristics of chlorine-free, quick continuous processing to reach and replace chlorination shrink-proof method completely, improve the not enough of exclusive use protease biological treatment technology, perfect protease biological treatment method, finally reach the optimal treatment effect, improve the purpose of full hair product quality.
