DESCRIPTION OF THE EMBODIMENTS
The technical schemes of the present disclosure are clearly and completely described. Apparently, the embodiments described are merely a part, rather than all of the embodiments of the present disclosure. The embodiments m the application and features in the embodiments may be combined with each other without conflict. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill tn the art without creative effort shall fall within the protection scope of the present disclosure.
One. Modification of a bamboo fiber
A bamboo fiber is put in an alkaline solution for soaking at room temperature for 1-3 hours; an antibacterial agent is added to obtain a mixture, and the mixture is subjected to standing at 75 °C to 195 °C for 6-8 hours; after the standing is completed, the mixture is rapidly heated to 160 °C to 180 °C for 30 seconds; and then dewatering and drying are conducted to obtain a modified bamboo fiber.
The alkaline solution 1s a sodtum hydroxide solution with a pH value of about 8.5. The bamboo fiber 1s soaked in the alkaline solution to make the surface of a fiber layer roughed, so that the interfacial compatibility 1s improved.
In the embodiment, the antibacterial agent includes a honeysuckle extract and poly(hexamethylenebiguanide) hydrochloride {(PHMB) and/or polyhexamethylene guanidine hydrochloride (PHMG).
The honeysuckle extract is used as a natural antibacterial material. Tt 1s found by the applicant that under alkaline conditions, the honeysuckle extract and the PHMB can be well bound and adsorbed to the surface of the fiber. Not only 1s the antibacterial effect of a fabric improved, but also the fabric has strong adhesion, long-lasting antibacterial effect, and great water washing resistance.
The dewatering includes dewatering by centrifugation at high speed, and after the dewatering by spin-drying is completed, the drying is conducted at a constant temperature of 40 °C to obtain the modified bamboo fiber.
In the embodiment, in addition to the modification of the bamboo fiber, a modification test is also carried out on a cotton fiber and other fabric fiber materials. However, the antibacterial effect is not as good as that of the bamboo fiber. The specific reason may be that a fiber structure of the bamboo fiber has strong adsorption and adhesion to the honeysuckle extract.
Two. Composition of a colored spun yam
In the embodiment, the composition of a colored spun yam is as follows: 5 70-90 parts of a cotton fiber, 10-20 parts of a modified fiber, 3-5 parts of a polyester fiber, and 3-5 parts of a polynostc fiber.
According to a preferred scheme, the colored spun yarn includes the followmg raw materials: 80 parts of the cotton fiber, 12 parts of the modified fiber, 3 parts of the polyester fiber, and § parts of the polynosic fiber.
In the embodiment, the cotton fiber in plant fibers in the fabric 1s used as a mam raw material, and all the modified fiber, the polyester fiber, and the polynosic fiber are added into the yarn to serve as functional fiber materials.
During selection of the raw materials, in addition to the cotton fiber, a hemp fiber and a fruit fiber in plant fibers and chinlon and a terylene fiber in synthetic fibers are selected at the same time. However, when the fibers are bound to the modified fiber, the problem of low persistence of the antibacterial effect 1s caused. When the polyester fiber and the polynosic fiber are optionally added, antibacterial and antistatic properties of the fiber are improved, and meanwhile, the adhesion of the antibacterial agent 1s also improved.
Three. Production method of a colored spun yarn
In the embodiment, a method for producing an antibacterial colored spun yarn includes the following steps:
Sl, separately dyeing cotton fibers at a ratio to obtain cotton fibers of different colors and types,
where according to a process in this step, the composition, blending ratio, color ratio and color requirements of raw materials are selected according to needs of a product, and a dyeing process 15 completed based on an existing mature technology:
S2, mixing the cotton fibers, a modified fiber, a polyester fiber, and a polynosic fiber at a set ratio, where in this step, the corresponding ratio is set according to the composition of specific spinning components in the embodiment; 53, sending a cotton roll to a carding machine for carding to obtain a fine cotton yarn fiber shiver, where in this step, a small cotton bundle is carded into a single fiber state by using a cover plate or roller type carding machine with the help of movement of a needle surface, impurities and non-spinnable short fibers are further removed, and the fibers are parallelly straightened and finally produced into a cotton sliver, which is wound into a shiver cylinder; and
S4, feeding the cotton sliver into a spinning machine to obtam a cotton yarn.
In this step, a specific process flow ts as follows.
I. A combing process:
Impurity removal, carding, and drafting are conducted by using an existing combing machine, and detailed steps are as follows: 1) impurity removal: cotton knots, impurities, and fiber defects in the fibers are removed, 2) carding: the fibers are further separated to remove short fibers, and 3} drafting: the cotton shiver is pulled to a specified fineness. 2. A drawing process:
Merging, drafting, mixing, and shivering are conducted by using an existing drawing machine, and detailed steps are as follows: 1) merging: various cotton slivers are merged to reduce the unevenness of long segments of the cotton shivers, 2) drafting: the cotton slivers are pulled and thinned to a specified weight,
3) mixing: the cotton shivers are mixed by a process on the drawing machine based on the merging and the drafting, and 4} slivering: coiling slivers are made into well-formed drawn shivers, and the drawn shivers are regularly wound in a cotton shiver cylinder. 3. A roving process:
The drawn shivers synthesized by drawing are subjected to drafting and twisting by using an existing roving frame, so that a yarn sliver has certain strength, winding of a roving yarn is facilitated, and unwinding of the yarn sliver on a spinning frame is facilitated. 4. A spinning process:
The roving yarn 1s drafted and pulled to a required fineness by using an existing spinning frame, and then twisted to form a spun yarn with certain twist and strength, and the spun yarn is wound on a bobbin.
Textiles processed from the colored spun yarn obtained by the above method of the present disclosure are washed with water for 5, 10, 15, 30, and 50 times respectively. After the water washing 1s completed, the textiles are dried at 60-70 °C at the same time. An antibacterial test is carried out on the textiles washed with water for different times. The antibacterial activity of Escherichia coli and Staphylococcus aureus 1s detected by using a parallel line drawing method (or a fringe method). According to detection results, if is shown that the antibacterial activity, namely the bacterial reduction rate, of a fabric can still reach 95.5% to the highest, and with the increase of the washing times, the antibacterial activity of the fabric 1s decreased slightly and still reaches 90.5%.
However, antibacterial clothing of An XX brand for children purchased from the market is used as a control in the test. After detection by the same process, the clothing has the highest antibacterial activity of 99 8%. However, with the continuous increase of the washing times, the antibacterial activity of the fabric is decreased to be less than 85%.
It should be understood that the examples and embodiments described herein are merely used for illustrating, rather than limiting the present disclosure.
Various modifications or changes can be made by those skilled in the art based on the examples and embodiments, and any modification, equivalent substitution, and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
