Description

A color-changing skin-friendly and cool elastic denim fabric

technical field

The invention relates to the field of textile and clothing fabrics, in particular to design a color-changing skin-friendly and cool elastic denim fabric.

Background technique

With the development of economy and technology and the improvement of people's living standards, people's demand for comfortable, fit and functional textiles is constantly changing. We need to continuously innovate them to meet consumers' improvement of spiritual and material quality of life. Denim fabric, as the most demanded textile fabric in textile products, produces high value-added textile products and will have broad market prospects.

Contents of the invention

The purpose of the present invention is to provide a reversible change in color after temperature stimulation, and at the same time, it can accumulate light energy from sunlight or light irradiation, and can emit light at night, and the fabric is crisp and soft to the touch, and has excellent moisture absorption, moisture conduction, and air permeability. , has good skin-friendly, cool, antibacterial and skin-protective properties, and is a color-changing skin-friendly and cool elastic denim fabric suitable for wearing in hot summer.

In order to solve the problems of the technologies described above, the technical solution selected by the present invention is as follows:

A color-changing skin-friendly and cool elastic denim fabric, which is formed by interweaving warp and weft yarns. The warp yarns are composed of first component warp yarns and second component warp yarns, wherein the first component warp yarns are selected from cotton fibers and silk The yarn formed by blending hemp fiber, the second component warp yarn is the yarn formed by blending cotton fiber and mica cool fiber; the weft yarn is composed of the first component weft yarn, the second component weft yarn and the third component weft yarn Composition, wherein the first component of the weft yarn is selected from the blended yarn of cotton fiber and silk and hemp fiber covered with core-spun yarn of T400 polyester elastic fiber; the second component of the weft yarn is selected from the blend of cotton fiber and light-storing polyester filament The yarn formed; the third component weft yarn is a yarn blended with Tencel and heat-sensitive color-changing fiber.

The warp and weft yarns of the color-changing skin-friendly and cool elastic denim fabric are interwoven according to the combination of three-up and one-down fabric weaves, one-up and four-down fabric weaves, and one-up and six-down fabric weaves.

The mass percentage of cotton in the first component warp yarn is 75-85%, the mass percentage of silk and hemp fiber is 15%-25%, and the mass percentage of cotton in the second component warp yarn is The percentage is 75-85%, and the mass percentage of mica cooling fiber is 15%-25%; the warp yarns of the first component and the warp yarns of the second component are arranged in a root number ratio of 1:1; The first component of the weft yarn is core-spun yarn, in which T400 polyester elastic fiber is made of elastic yarn formed by parallel composite spinning of two different polyester fibers other than spandex, PET and PTT, as the core yarn, and the outsourcing cotton fiber and silk hemp The blended yarn of fiber; The blended ratio of described cotton fiber and silk hemp fiber is 75:25, and the blended yarn of described cotton fiber and silk hemp fiber is 70:30 with T-400 quality sheath-core ratio; So The second component weft yarn is a yarn blended with cotton fibers and light-storing polyester filaments, the mass percentage of the cotton fibers is 90%-98%, and the mass percentage of the light-storing polyester filaments is The percentage is 2%-10%; the third component weft yarn is a yarn blended with tencel and heat-sensitive color-changing fibers, and the mass percentage of the tencel is 90%-98%. The mass percentage of heat-sensitive color-changing fibers is 2%-10%; the first component weft yarn and the second component weft yarn are arranged in a root number ratio of 16:5, and the first component weft yarn and the third group weft yarn The divided weft yarns are arranged in a ratio of 20:7.

The beneficial effects of the present invention are: the color-changing, skin-friendly and cool elastic denim fabric of the present invention is formed by interweaving warp and weft yarns. The warp yarn is composed of a first component warp yarn and a second component warp yarn, wherein the first component warp yarn is a yarn blended with cotton fiber and silk fiber, and the second component warp yarn is selected from cotton fiber and A yarn made from a blend of mica cooling fibers. Silk hemp viscose staple fiber closely combines the excellent characteristics and styles of silk and hemp fiber fabrics through certain technical means to form a new regenerated cellulose fiber. Mica cooling fiber is a new type of cooling and heat dissipation material that uses polyester as a carrier to integrate nano-mica, which uses the unique properties of the fiber itself to keep the fabric cool. The application of silk and hemp fiber and mica cooling fiber makes the appearance of denim fabric have the appearance effect of real silk. comfort performance.

In the present invention, the first component weft yarn is core-spun yarn, wherein T400 polyester elastic fiber is the elastic yarn formed by side-by-side composite spinning of two different polyester fibers other than spandex, PET and PTT, as the core yarn, and the outsourcing cotton fiber Yarn blended with silk and hemp fibers. T400 polyester elastic fiber has excellent elastic recovery, anti-wrinkle and other properties, so that the denim fabric is not easy to deform, and the shape retention has been improved to a certain extent. The second component of the weft yarn is made of cotton fiber and light-storage polyester filament. The application of light-storage fiber allows the denim fabric to store light energy and glow in the dark after being exposed to sunlight or light, especially at night. Places with high requirements for safety and visibility make denim fabrics have a certain degree of safety, reminding vehicles and pedestrians in the dark night to avoid some traffic accidents. The third component weft yarn is a yarn blended with Tencel and heat-sensitive color-changing fibers. Thermosensitive color-changing fiber is a fiber with special composition or structure that can automatically change color after being stimulated by light and external temperature, and this color change is reversible. The application of color-changing fibers enriches the color of denim fabrics, produces novel color changes to improve the taste of denim fabrics, and satisfies consumers' transformation of modern denim fabrics from practicality to individuality and richness. In addition, heat-sensitive color-changing fibers and light-storing polyester filaments are used in the arrangement of weft yarns for weaving, so that denim fabrics produce lateral color changes during the day under the stimulation of sunlight or temperature; at night, due to light-storing polyester filaments When illuminated by sunlight or light, it accumulates light energy, and in the dark night, it can produce horizontal luminescence, thereby improving the safety of pedestrians walking on the road. The color-changing skin-friendly cool denim fabric can produce horizontal color changes at different times, enriches the color of the denim fabric, improves the functionality of the denim fabric, thereby better meeting the ever-changing needs of consumers, and at the same time its cool and friendly Clothes are suitable for wearing in hot summer.

To sum up, the present invention designs a functional denim fabric with the atmosphere of the times while perfecting its requirements for people's comfortable wearing performance, thereby improving the taste of the denim fabric, realizing the complementarity of various fiber properties, and satisfying people's clothing personality. needs.
