Description

Technical Field

[0001] This invention relates to the technical field of worsted fabrics, and in particular to a four-way stretch fabric with deodorizing, UV-resistant, moisture-wicking and perspiration-absorbing functions and its preparation method. Background Technology

[0002] Four-way stretch fabric is a type of elastic fabric, also known as four-dimensional or full-stretch fabric. It is made of spandex, elastic fibers, or a blend of spandex and has a high degree of elasticity in both the horizontal and vertical directions. Compared to ordinary two-way or one-way stretch fabrics, four-way stretch fabric can better adapt to the curves of the body and changes in movement, providing a closer fit and a comfortable and free wearing experience.

[0003] Four-way stretch fabric is widely loved by consumers for its comfort and style. In the production of four-way stretch fabric, conventional raw materials such as wool, polyester, and viscose are usually used. The resulting four-way stretch fabric has a shrinkage rate of more than 1.5% after washing and cannot be machine washed multiple times. Furthermore, the resulting four-way stretch fabric cannot meet the functional requirements of daily wear such as antibacterial, odor-proof, UV-resistant, and moisture-wicking properties, as well as the easy care function of being machine washable.

[0004] Therefore, how to effectively improve the shrinkage rate of four-way stretch fabric after washing and increase its antibacterial, deodorizing, UV-resistant, and moisture-wicking functions has become an urgent problem to be solved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a four-way stretch fabric with odor-resistant, UV-resistant, moisture-wicking, and perspiration-absorbing functions, as well as a method for its preparation.

[0006] This application discloses a four-way stretch fabric with deodorizing, UV-resistant, moisture-wicking, and perspiration-absorbing functions and its preparation method. It adopts a new type of environmentally friendly functional fiber and a special spinning process to give the fabric antibacterial, deodorizing, UV-resistant, moisture-wicking, and machine-washable functions, making it suitable for spring, autumn and winter outerwear fabrics and increasing the functionality of wool four-way stretch fabrics.

[0007] In a first aspect, this application provides a four-way stretch fabric with odor-resistant, UV-resistant, moisture-wicking, and perspiration-absorbing functions, employing the following technical solution:

[0008] A four-way stretch fabric with deodorizing, UV-resistant, moisture-wicking and perspiration-absorbing functions, the fabric is made of interwoven warp and weft yarns, the warp yarns include 50-65 parts by weight of coffee fiber and 35-47 parts by weight of merino wool, and the weft yarns include 30-50 parts by weight of spandex core-spun yarn.

[0009] In this application, coffee fiber and Merino wool are used to prepare four-way stretch fabric, and the resulting fabric has a comfortable stretch and wrinkle resistance.

[0010] Coffee fiber, also known as iced coffee fiber, is a new type of environmentally friendly fiber made from Starbucks coffee grounds. It has a porous structure and features deodorization, UV protection, moisture absorption, and quick-drying properties.

[0011] Merino wool, also known as Merino shrink-resistant wool, meets the requirement that wool can be machine washed.

[0012] Preferably, the spandex core-spun yarn comprises 70-90 parts by weight of a central spandex filament, and a yarn fiber layer is wrapped around the central spandex filament. The yarn fiber layer comprises the following raw material components in parts by weight: 10-20 parts of bamboo fiber and 5-10 parts of chitosan fiber.

[0013] And 5-10 parts of seaweed fiber.

[0014] Spandex core-spun yarn is Siro-spun spandex core-spun yarn; that is, the worsted single yarn of compact Siro-spun spandex core-spun yarn.

[0015] This application improves the raw material of spandex core-spun yarn by adding bamboo fiber, chitosan fiber, and seaweed fiber. The added bamboo fiber has moisture-wicking properties, can quickly absorb moisture, and has antibacterial and deodorizing properties. The added chitosan fiber has broad-spectrum antibacterial properties, which can improve the antibacterial properties of the fabric. The seaweed fiber has high strength, softness, moisture absorption and warmth retention, antibacterial, anti-ultraviolet and anti-oxidation properties. The added seaweed fiber can effectively prevent bacterial growth, thereby reducing mildew on clothes and keeping clothes fresh.

[0016] This application improves the raw material of spandex core-spun yarn, and can prepare spandex core-spun yarn with moisture-wicking, antibacterial, UV-resistant and soft hand feel.

[0017] Preferably, the spandex core-spun yarn is pretreated by the following steps: the spandex core-spun yarn is placed into a pretreatment solution for reaction to obtain pretreated spandex core-spun yarn.

[0018] Preferably, the mass-to-volume ratio of spandex core-spun yarn to pretreatment liquid is (80-110):(100-200).

[0019] Preferably, the reaction time is 0.5-1.5 hours and the temperature is 30-45℃.

[0020] Preferably, the pretreatment solution comprises the following raw material components in parts by weight: 80-90 parts chitosan, 1-5 parts starch, 15-25 parts citric acid, and 3-7 parts mangosteen peel extract.

[0021] In this application, by improving the pretreatment solution formula, chitosan and citric acid with deodorizing functions are added. Chitosan contains a large number of amino and hydroxyl groups. The amino groups can adsorb bacteria and combine with anions of the cell wall, thus hindering the biosynthesis of the cell wall and achieving the effect of antibacterial and deodorizing. The added citric acid has a deodorizing function, which improves the deodorizing performance of spandex core-spun yarn.

[0022] In this application, by improving the formula of the pretreatment solution, mangosteen shell extract is added. Mangosteen shell extract has antioxidant, anti-allergic and antibacterial effects, and it also has a good anti-ultraviolet radiation effect, thereby improving the anti-ultraviolet radiation performance of spandex core-spun yarn.

[0023] In this application, by improving the pretreatment solution formula, and through the synergistic effect between chitosan, starch, citric acid, and mangosteen peel extract, a spandex core-spun yarn with antibacterial, moisture-wicking, deodorizing, UV-resistant, and soft-hand feel is prepared.

[0024] Preferably, the preparation steps of the pretreatment solution are as follows: react chitosan with starch, add citric acid to react, and then add mangosteen peel extract to mix, thus preparing the pretreatment solution.

[0025] In this application, the pretreatment solution preparation process is improved by adding an excess of chitosan. The added chitosan first reacts with starch to prepare chitosan-modified starch. The remaining chitosan undergoes a grafting reaction with citric acid. Due to the strong reactivity of the amino group at C2 in the chitosan molecule, it can undergo a grafting reaction with the -COOH group in the carboxylating agent citric acid to obtain citric acid-modified chitosan. After the chitosan-modified starch undergoes the grafting reaction with citric acid, the citric acid-modified chitosan is loaded to obtain a mixture with high hygroscopic and moisturizing properties. The mixture with high hygroscopic and moisturizing properties is loaded with mangosteen peel extract to obtain a pretreatment solution with antibacterial, hygroscopic, perspiration-wicking, deodorizing, and UV-resistant properties.

[0026] Secondly, this application provides a method for preparing a four-way stretch fabric with deodorizing, UV-resistant, moisture-wicking, and perspiration-absorbing functions, using the following technical solution:

[0027] A method for preparing a four-way stretch fabric with odor-resistant, UV-resistant, moisture-wicking, and perspiration-absorbing functions, the preparation process is as follows:

[0028] 1) Preparation of warp and weft yarns;

[0029] 2) Warping: Coffee fiber and Merino wool are used as warp yarns and warped onto the warp beam according to the specified ratio;

[0030] 3) Weaving: Spandex core-spun yarn is used as weft yarn and interwoven with warp yarn in a 24:24 arrangement to form greige fabric, thus obtaining four-way stretch fabric.

[0031] Preferably, the four-way stretch fabric obtained in step 3) is post-processed as follows: the prepared four-way stretch fabric is subjected to air beating.

[0032] The preferred reaction conditions for air beat-up are: reaction temperature 120-150℃, wind force 85-95%, and vehicle speed 6-10 meters / minute.

[0033] In this application, the prepared four-way stretch fabric is subjected to an air-beating process to completely eliminate the internal stress of the fabric, resulting in a softer feel and more stable shrinkage rate after washing.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. This application discloses a four-way stretch fabric with deodorizing, UV-resistant, moisture-wicking and perspiration-absorbing functions and its preparation method. By improving the raw materials and preparation method of the four-way stretch fabric, a four-way stretch fabric with antibacterial, deodorizing, UV-resistant, and moisture-wicking functions is prepared, and the hand feel of the four-way stretch fabric is improved.

[0036] 2. The four-way stretch fabric prepared by the method of this application has a pilling resistance of 4-5 and a washing shrinkage of less than 1.5%, which greatly improves the performance of the four-way stretch fabric. Detailed Implementation
