Description

Preparation method and application of wear-resistant composite fabric
Technical Field
The invention relates to the technical field of composite fabrics, in particular to a preparation method and application of an abrasion-resistant composite fabric.
Background
Since 1873, jean fabric has undergone the evolution from basic use to fashion trend, and is wear-resistant and free of individuality due to the rough surface style, and is popular with people. Over the evolution of the 3 centuries, the enthusiasm and the demands of jeans garments have not been reduced until now. The jean clothing industry occupies an important position in the national economy of China.
Along with the improvement of the living standard of people and the proposal of the low-carbon green environment-friendly concept of the textile industry, the consumption concept of the jeans is changed, the demands of wearing comfortable, leisure and multifunctional clothing are continuously increased from the beginning to the beginning, the jeans production enterprises also put higher demands on the production and weaving of jeans, and yarns and fabrics with more excellent performances and energy-saving and environment-friendly production processes are expected to be obtained. The existing jean fabric has certain wear resistance, but has good antibacterial effect and skin contact feeling, and the fabric capable of increasing the touch feeling on the premise of improving the wear resistance is needed.

Performance test
In order to further study the performance parameters of the wear-resistant composite fabric, the application further carries out the verification of the following examples.
1. Wear resistance of fabrics
The experiment adopts a flat friction method to measure the resistance of the composite fabric after zero water washing and quantitative times of water washing, and the characterization index is friction quality loss, and the larger the quality loss rate is, the better the wear resistance of the fabric is. The abrasion resistance of each group of fabrics was subjected to abrasion tests at 300, 800 and 1200 turns in turn, and the mass loss percentage was calculated.
2. Breaking performance of fabric
Bursting refers to the phenomenon that a part of a fabric is destroyed under the action of external force perpendicular to the plane of the fabric, and the higher the bursting strength is, the better the bursting performance of the fabric is. The bursting performance of the jean fabric after zero water washing and multiple water washing is measured by adopting a spherical ejector rod in the experiment. And testing bursting strength of each fabric after different washing times.
3. Mechanical properties of fabrics
The fabric stretchability refers to the fact that the fabric generates a stretch breaking phenomenon when bearing a certain tensile load, so that a test method of constant force elongation (constant load 25N) is selected in an experiment, and mechanical stretching tests are carried out on the composite fabric after different washing times.
4. Antibacterial Performance test the composite fabric was subjected to an antibacterial test according to the modified AATCC 100-1999 standard test method, and the inoculated bacteria were staphylococcus aureus (ATCC 6538) and escherichia coli (ATCC 43895) to calculate the bactericidal rate by counting the number of surviving bacteria. Where the staphylococcus aureus concentration was 1.50×106CFU in the test and the escherichia coli concentration was 3.76×106CFU in the test.
TABLE 2 Performance test experiment Table for examples 1-9, comparative examples 1-2
Conclusion analysis
Analysis was performed according to the above test, and the most significant damage in clothing and household use was due to abrasion caused by abrasion of different forms and sizes of abrasion operations, after which the fabric fibers were broken, detached, pulled out and disintegrated. The friction part of the fabric will produce quality loss, and the loss rate of quality loss can be used for judging the fabric loss condition. The wear resistance of the fabric is analyzed after the fabric is washed for 0 times, 20 times and 40 times. In addition, the bursting strength, the breaking strength and the breaking elongation of the composite fabric are increased along with the washing times, and the composite fabric is in a descending trend. The reason is that the more the washing times are, the fabric is gradually reduced in mechanical property under the repeated action of mechanical external force after the fabric is continuously washed, dried, rubbed and ironed for many times in the washing process, and the fluff on the surface of the fabric is reduced and thinned, so that the bursting force and the mechanical property of the fabric are reduced. Because the polyester fiber and the cotton fiber are added into the first spinning yarn and the second spinning yarn, the polyester fiber and the cotton fiber have better elastic recovery property, so that certain elasticity is still kept after the water washing for a plurality of times, further better mechanical property can be kept,
From the analysis of examples 1-9, example 5 is a preferred example, wherein when the raw material of the first spun yarn is modified polylactic acid fiber, polyester fiber, cotton fiber, the raw material of the second spun yarn is spandex fiber, cotton fiber, and the raw material of the third spun yarn is spandex fiber, polyester fiber.
In addition, when the polyester fiber is not added to the first fabric in combination with comparative examples 1 to 2, the abrasion resistance and various mechanical properties thereof are reduced, because polylactic acid has more excellent mechanical properties. However, the improvement in the properties is not high because the polylactic acid is not modified and further investigation is required.
In addition, by wherein the modified polylactic acid fiber is added with titanium dioxide modified with polylactic acid oligomer during the modification process, since titanium metal has a specific role in skin morphogenesis and function. Therefore, the titanium ion as exogenous ion can destroy the ecological balance of bacteria, but has little influence on the skin of human body, thereby being capable of improving the antibacterial effect and reducing the injury of the skin of human body.
Example 10
Example 10 differs from example 5 in that the modified oligomer of TiO 2 is an oligomer-modified TiO 2 of polylactic acid.
Example 11 is different from example 5 in that the polylactic acid chips were right-handed polylactic acid (PDLA).
Example 12 differs from example 5 in that the polylactic acid chips were made of racemic polylactic acid (PDLLA).
Performance test
In order to further study the performance parameters of the wear-resistant composite fabric, the application further carries out the experiment and performs the verification of the embodiment. Specific data are shown in the following test table.
TABLE 3 Experimental Table of Performance test of examples 5,10-12
Conclusion analysis
Example 12 is the preferred example, wherein the modified oligomer of TiO 2 is TiO 2 surface coated with polycaprolactone when the modified polylactic acid fiber is modified in accordance with the above test. And the polylactic acid slice adopts racemic polylactic acid (PDLLA).
In addition, in the process of blending the modified polylactic acid with the blended yarn, the application adopts the mixture of acetone and chloroform, so that the uniformity of materials in spinning can be improved, the spinning time is improved, and the toughness of the composite fiber can be further improved.
