Description

Technical Field

[0001] The invention relates to an environmentally friendly silk foaming agent and a preparation method thereof, in particular to a synthesis and compounding method of a bio-based foaming agent for improving the smoothness and softness of raw silk, belonging to the technical field of textile auxiliaries. Background Art

[0002] Due to the increasing depletion of oil resources and the environmental pollution caused by petroleum-based chemicals, vigorously developing degradable, recyclable and renewable bio-based chemicals by using renewable resources such as plant extracts as raw materials will help achieve sustainable industrial development and become an effective way to solve resource and environmental problems.

[0003] Silk fiber is mainly composed of fibroin and sericin wrapped outside the fibroin. The sericin wrapped outside protects the fibroin, but the presence of sericin will also cause the silk fiber to be insufficiently smooth and soft, so the silk needs to be soaked to improve the subsequent processing performance. After the silk is soaked in a soaking agent, the sericin can be softened and evenly distributed on the surface of the fibroin, reducing the rough blocks and hard corners adhering to the surface of the silk; at the same time, the addition of the soaking agent helps to form a protective film on the silk, thereby increasing the adhesion, smoothness and softness of the silk surface, and improving the subsequent processability and fabric quality of the silk. In addition, according to different usage requirements, the soaking agent can be subdivided into warp soaking agent and weft soaking agent. The warp soaking agent mainly makes the warp silk appropriately smooth and wear-resistant; the weft soaking agent mainly makes the weft silk soft.

[0004] Since silk is a high-end natural skin-friendly product, the use of too much petroleum-based chemicals during the processing process will pollute the silk and reduce its natural value. As the concept of green environmental protection is deeply rooted in people's hearts, the use of bio-based chemicals helps to protect the natural green properties of silk itself. At present, the silk soaking agents used in silk are all petrochemical-based products, and some silk soaking agents will leave wax that is difficult to remove on the surface of the silk after use, causing defects in the finished product, thereby affecting its quality. For example, the compounding agents used in a solid silk soaking agent and its preparation method in Chinese patent CN108385380B are all petroleum-based derivatives, and paraffin is not easy to remove, and it is easy to form wax on the raw silk; although vegetable oil is used in the silk soaking agent in Chinese patent CN103710966B, the other chemicals added are all petroleum-based products, which is not conducive to maintaining the naturalness of silk.

[0005] Therefore, in order to maintain the high naturalness of silk itself, developing a silk soaking agent with high naturalness, good silk soaking effect and effective reduction of carbon emissions is a technical problem that needs to be urgently solved in the silk processing industry.

When feeding, the material is loaded into the feeding seat, and the feeding seat is fixed to the bottom end of the square frame through the cooperation of parts in the connecting mechanism. At this time, the guide pipe discharges nitrogen into the feeding shell to prevent air from entering; the partition plate is pushed to move to close the bottom end of the feeding shell, and the baffle plate is rotated to open one end of the feeding shell, and the third motor is started to drive the feeding seat to move into the inner cavity of the kettle body. The feeding operation is carried out through the cooperation of parts in the connecting mechanism, so that air is prevented from entering the kettle body when feeding the kettle body.

[0100] The application equipment is the same as that in Example 1 and will not be described in detail here.

[0101] The application of the environmentally friendly silk soaking agent of the present invention is to apply the present invention to silk, especially to the soaking and softening finishing process. Specifically, the silk is soaked with a bio-based silk soaking agent prepared in Examples 1 to 5. The soaking process is: the amount of the soaking agent is 4% (owf), the temperature is 40°C, the bath ratio is 1:5, the soaking time is 1h, and after soaking, the various silks are dehydrated and hung on a silk cooling rod to dry.

[0102] Blank example

[0103] This comparative example is silk that has not been treated with a silk soaking agent.

[0104] Comparative Example 1

[0105] This comparative example uses commercially available silk soaking agent 1 according to the process conditions: soaking agent dosage 8% (owf), temperature 40°C, bath ratio 1:5, soaking time 1h, dehydrating the silk after soaking, hanging it on a silk cooling rod to dry, and soaking the silk.

[0106] Comparative Example 2

[0107] This comparative example uses commercially available silk soaking agent 2 according to the process conditions: soaking agent dosage 7.5% (owf), temperature 40°C, bath ratio 1:5, soaking time 1h, dehydrating the silk after soaking, hanging it on a silk cooling rod to dry, and soaking the silk.

[0108] Performance testing and characterization:

[0109] 1. Cohesion test: The cohesion performance of raw silk is tested according to GB / T1798-2008 "Raw Silk Test Method" standard. Test method: The silk strips are continuously placed between 10 hooks on both sides of the cohesion machine frame. Under constant and uniform tension, different parts of the silk strips are rubbed at the same time, and the friction speed is about 130 times / min. When the friction reaches about 45 times, the first observation is made. After a certain number of frictions, the machine should be stopped to carefully observe the degree of silk strip splitting. When more than half of the silk strips have cracks of 6mm or more, the number of frictions is recorded. Randomly select 10 sections of silk for testing, record the number of frictions and take the average value. The larger the test value, the better the cohesion of the raw silk.

[0110] 2. Silk strength test: The breaking strength, elongation at break and initial modulus of raw silk were tested using a yarn tensile tester. The determination method was carried out in accordance with GB / T1798-2008 Raw Silk Test Method. The clamping distance was adjusted to 500mm, the stretching speed was set to 500mm / min, and the pre-tension was 0.05cN / dtex. Before the test, the sample silk to be tested was first placed in a constant temperature and humidity chamber for more than 12 hours. The temperature of the constant temperature and humidity chamber was set to (20±2.0)℃ and the humidity was (65.0±4.0)%. The breaking strength, elongation at break and softness of the sample silk were tested using a yarn tensile tester. The softness was the initial elastic modulus of the sample silk. There were 50 valid samples and the average value was taken.

[0111] 3. Silk friction coefficient test: Use a friction coefficient meter to test, take 30 valid samples, and take the average value. The smaller the friction coefficient, the smoother the silk surface.

[0112] Table 1 - Test results after silk soaking

[0113]

[0114] As can be seen from Table 1, compared with the commercially available comparative examples 1-2, the cohesion, strength and friction coefficient test data of the silk after soaking are significantly improved in the embodiments 1-5 of the present invention, provided that the amount used is only one-half of the comparative example; at the same time, the silk after soaking of the products of the present invention feels soft and smooth, has no odor, and does not leave waxy defects after dyeing, while the silk processed by the comparative example 1 product will leave waxy defects, and the silk processed by the comparative example 2 product will be slightly hard and have odor. The silk soaking agent of the present invention will obtain considerable social and economic benefits.

[0115] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
