The wool product has the characteristics of full hand feeling, good heat retention, comfortable wearing and the like, is famous and elegant, and is comfortable to wear in natural style, and particularly has the name of 'soft gold' in cashmere. However, the wool fiber surface is coated with a compact scale layer and a hydrophobic phospholipid layer, which causes poor wettability, easy felting deformation and bacteria breeding of wool, and the use of wool fabric is greatly limited. It is therefore essential to modify wool fibers to improve the machine-washability, aesthetics and wearing comfort of the fabric. The felting property refers to the property that the scale impaction can not be reduced and loosened and the fiber is mutually interpenetrated, entangled, shrunk and felted under the action of repeated mechanical external force (especially pressing and kneading) of the wool fiber aggregate under a certain damp and hot medium condition. The felt shrinkage deformation of the wool fibers can greatly reduce the heat retention, the attractiveness and the wearing comfort.

S2, guiding the wool fabric processed in the step S1 into an ozone gas chamber in a tension-free long-ring mode, processing the wool fabric by ozone, and washing and drying the wool fabric to obtain the wool fabric with the shrink-resistant property.

The concentration of ozone in the ozone chamber is 8-12 g/h, and the time of ozone treatment is 10-30 min. In the step, the wool fabric is slowly led out at a constant speed in the ozone chamber according to the preset treatment time and the stroke in the ozone chamber, so that the continuous processing is realized. In addition, the wool fabric is led into the ozone gas chamber in a tension-free long-ring mode, namely the wool fabric is processed in a loose tension-free mode, and the structure, the state, the density and the like of the wool fabric can be well kept.

Examples 1 to 3 and comparative examples 1 to 4

A continuous processing method for improving the shrinkability of wool fabrics comprises the following steps:

s1, preparing an aqueous solution containing 1-5 wt% of sodium hypochlorite and 1-3 wt% of ethanol as a treatment solution, and padding wool fabrics in the treatment solution, wherein the padding rate is 80-100%;

s2, guiding the wool fabric treated in the step S1 into an ozone gas chamber in a tension-free long-ring mode (the ozone concentration is 8-12 g/h), treating the wool fabric with ozone for 10-30 min, and washing and drying the wool fabric to obtain the wool fabric with the shrink-resistant property.

Wherein, the import and the export of ozone chamber all adopt the liquid seal structure, and the liquid seal structure of import adopts above-mentioned treatment fluid to be liquid seal liquid, and the liquid seal structure of export adopts water to be liquid seal liquid.

Carrying out a shrinkage rate test by adopting the GB/T8629 and 2017 household washing and drying program for textile test; GB/T4802.3-2008 < determination of pilling behaviour of textile fabrics part 3: the pilling resistance evaluation was carried out in accordance with the pilling box method, and the results are shown in Table 1.

TABLE 1 Process parameters and Performance test results for examples 1-3 and comparative examples 1-4

As can be seen from table 1, the area shrinkage of the virgin wool fabric without any treatment after 3 washes was 8.2%, and the pilling resistance rating was 2.0; through the shrink-proof treatment, the minimum area shrinkage of the wool fabric after 3 times of washing can reach 1.5 percent, and the anti-pilling performance grade can reach 4.2 grade. When ozone treatment is not carried out, the area shrinkage rate after 3 times of washing is increased to 7.6%, and the anti-pilling performance grade is reduced to 2.3 grade. When no ethanol is added into the treatment liquid, the area shrinkage after 3 times of washing is increased to 2.8%, and the anti-pilling performance grade is reduced to 3.7 grade. When the treatment liquid was not used, the area shrinkage increased significantly, and the pilling resistance rating decreased. Therefore, the invention obviously improves the shrinkproof property and the pilling resistance of the wool fabric by adding ethanol into the treatment fluid and matching with ozone treatment.

Example 4

A continuous processing method for improving the shrinkability of wool fabrics adopts a device shown in figure 1, and comprises the following steps:

s1, preparing an aqueous solution containing 3 wt% of sodium hypochlorite and 3 wt% of ethanol as a first treatment solution, adding the first treatment solution into a first liquid tank 10, submerging a first water baffle 11, and padding wool fabrics in the treatment solution, wherein the padding rate is 90%; preparing an aqueous solution containing 1 wt% of sodium hypochlorite and 3 wt% of ethanol as a second treatment solution, adding the second treatment solution into a second liquid tank 20, and submerging a second water baffle 21;

s2, guiding the wool fabric processed in the step S1 into a first ozone air chamber 42 (the ozone concentration is 10g/h) through a cloth guide roller 50 in a tension-free long-ring mode, and processing the wool fabric for 15min through ozone; and then the wool fabric is led into a second liquid tank 20, after padding treatment, the wool fabric is led into a second ozone air chamber 43 (the ozone concentration is 10g/h), and after ozone treatment is carried out for 15min, the wool fabric is washed and dried, and the wool fabric with the anti-felting property is obtained.

Through detection, the area shrinkage of the wool fabric prepared in the embodiment after 3 times of washing is 1.3%, and the anti-pilling performance grade can reach 4.3 grade. It can be seen that the treatment time was substantially unchanged, and the effect slightly superior to that of the single treatment was achieved by the multiple treatment solutions and the ozone treatment. Moreover, the multiple integrated liquid seal treatment device can further improve the continuity and controllability of the shrink-resistant treatment. When the treatment liquid in the second liquid tank 20 is adjusted, the treatment effect can be further adjusted.

In summary, the continuous processing method and device for improving the anti-felting property of the wool fabric provided by the invention adopt the integrated liquid sealing device consisting of sodium hypochlorite, ethanol treatment liquid and an ozone gas chamber to carry out continuous processing. The wool fabric is directly led into an ozone air chamber after being padded and processed by an imported liquid seal structure, and is continuously led out after being dipped and washed by an exported liquid seal structure after being processed by ozone, so that large-scale continuous processing is realized, the whole shrink-proof wool processing device and procedure are obviously simplified, and the continuous processing efficiency is improved.
