Technical Field
The invention relates to the technical field of textile materials, in particular to a high-strength wear-resistant textile fiber.
Background
The traditional garment fabric is mainly made of fabrics woven by cotton, hemp, silk and other materials. The fabric is made of pure natural materials, has better affinity with human bodies, is comfortable to contact with skin and is not easy to sensitize. However, the fabric is dependent on planting or breeding, the yield per year is limited, the cost is high, and the functionality is poor. Moreover, the fabric has limited strength and no wear resistance, and is generally not durable after being made into ready-made clothes.
Along with the change of the market, the requirements of people on the comfort and the functionality of work clothes are continuously improved, and on the basis of the traditional comfortable wearing, other functions such as water resistance, ventilation, perspiration, moisture removal and the like are also required. The traditional cotton and linen fabric is difficult to adapt to the functional requirements of the current market. With the progress of materials science, various functional fibers are widely developed and used in the textile field. By adding the functional fiber, the textile fabric can be endowed with the characteristics of moisture absorption, quick drying, heat preservation, antibiosis, wear resistance and the like, and the wearability and the added value of the product are greatly improved.
The existing wear-resistant fabric is generally made of blended fibers, namely, on the basis of cotton or hemp, the corresponding functional requirements are met by mixing other functional fibers, and chemical fibers such as nylon, spandex, terylene and the like are generally selected to be mixed in the cotton and hemp fibers. However, such fabrics also have certain problems. Firstly, because chemical fibers are poor in contact feeling and have certain sensitization, the comfort level of the chemical fibers in contact with the skin is inferior to that of natural fibers such as cotton and linen, in order to ensure the comfort, the cotton and linen ratio is generally large (more than 85%), and the chemical fibers ratio is small, so that the improvement of the wear resistance is limited. Secondly, the blended fiber has certain difficulty in preparation due to different characteristics of various materials, the preparation cost is relatively high, and the process control is difficult. Finally, the blended fiber is generally made by blending short fibers made of various materials, and has poor tear resistance and low strength.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1 to 3, the high-strength and wear-resistant textile fiber designed according to one embodiment of the present invention includes a single core yarn and 2 to 4 blended yarns, which are blended together.
The core wire and the blended wire are prepared by adopting a specially designed process, and then are mixed to prepare the textile fiber, and the specific preparation process is as follows.
As shown in fig. 1, the core wire preparation process of the present invention is as follows:
the core wire comprises 5-10% of functional polyester, 20-25% of Doctoria fiber and the balance of cotton fiber.
The functional polyester and the Doctoria fiber are subjected to antistatic treatment and cotton grabbing procedures, then are subjected to cotton mixing and coiling procedures with the cotton fiber, then are subjected to cotton carding procedure, and finally are subjected to combing procedure to prepare the rough strips.
Preferably, the functional polyester is modified polyester, and preferably coffee carbon modified polyester is adopted.
As shown in fig. 2, the preparation process of the blended yarn of the present invention is as follows:
the blended yarn comprises 30-35% of Doctoria fiber and cotton fiber.
The Kodora fiber is subjected to anti-static treatment and cotton grabbing procedures, then is subjected to cotton mixing and coiling procedures with the cotton fiber, then is subjected to cotton carding procedure, and finally is subjected to combing and padding procedures to prepare the rough strips.
As shown in fig. 3, the blending process of the present invention is as follows:
the core wire and the blended yarn are made into strips through a blending process, and then the high-strength and wear-resistant textile fiber is made through roving, spinning and spooling processes.
The fibers adopted by the invention are all short fibers, so that the process is simple and easy to control.
The functional polyester fiber, the Doctoria fiber and the cotton bag mixed core wire are adopted, the characteristics of high strength and tear resistance of the Doctoria fiber are utilized, the characteristic that the functional polyester fiber is easy to modify and infiltrate is also integrated, and the coffee carbon modified polyester fiber is preferably adopted, so that the functional polyester fiber core wire has high strength, can further improve the tear resistance and the tensile strength of the core wire, has better toughness, can have deodorization performance and has better ultraviolet resistance. After the coffee carbon terylene is blended, the tear resistance and the tensile strength of the core wire are much higher than those of the pure Codura blended cotton fiber, and the coffee carbon terylene has an unexpected strength improvement effect.
Considering that the polyester fiber has poor touch and is not comfortable when contacting with skin, the polyester fiber is considered to be used as a core wire to improve the overall strength performance of the finished fiber yarn as an aggregate.
The invention fully considers the comfort of contacting with the skin and adopts pure codola fiber blended cotton thread as blended thread. The strength of the fiber yarn is lower than that of the core yarn but higher than that of the cotton yarn, and the fiber yarn prepared by mixing the fiber yarn with the core yarn still has better tear resistance and tensile strength under the support of the aggregate. And secondly, the blended yarn improves the proportion of the Doctoria fiber, fully utilizes the wear-resistant characteristic of the Doctoria fiber, and can endow the final fiber yarn with better wear-resistant performance.
Among the above embodiments, the present invention is still a more preferred embodiment. In a preferred embodiment, the coiling process of the core wire and the blended wire controls the length of the lap to be within 28 m.
This is because the Codura fiber has poor cohesive force and the formed lap is not good. Repeated tests of the inventor show that the length of the cotton roll is reduced to be within 28m, so that the cotton roll can be prevented from being stuck and can be well formed.
Among the above embodiments, the present invention is still a more preferred embodiment. In a preferred embodiment, the core wire and the blended wire are subjected to a drawing and lap process after the carding process, and then subjected to a combing process.
The treatment can remove redundant fluff and miscellaneous fibers, eliminate pilling points and bad thread points and effectively improve the quality of the fiber threads.
Among the above embodiments, the present invention is still a more preferred embodiment. The padding procedure is to pad the weak acid water absorption quick-drying agent.
The improvement can endow the fiber yarn with sweat absorption and quick drying functions.
