Description

Technical Field

[0001] This invention relates to the field of knitted fabric technology, and in particular to a single-layer effect alkali-reducing, lightweight, quick-drying, antibacterial weft-knitted fabric and its production method. Background Technology

[0002] As autumn approaches and temperatures gradually cool, consumers' demands for sportswear have increased beyond just comfort and skin-friendliness. They now also prioritize lightweight, quick-drying, and antibacterial properties to ensure a comfortable wearing experience during exercise. Traditional knitted fabrics, with their softness, unique stretch, and lightweight, quick-drying, and antibacterial characteristics acquired during the weaving and dyeing process, have become the preferred choice for layering clothing in autumn and winter. However, traditional knitted fabrics also suffer from various problems, including easy deformation after washing, poor wrinkle resistance, insufficient comfort, and more.

[0003] In view of this, the inventor, in order to address the numerous shortcomings and inconveniences caused by the imperfections in the aforementioned fabrics and their production methods, has conceived and actively researched and experimented with improvements to develop this invention. Summary of the Invention

[0004] The purpose of this invention is to provide a single-layer effect alkali-reduced lightweight quick-drying antibacterial weft-knitted fabric and its production method. This fabric is woven from microporous blended yarns of cotton, polyester, modal and other fibers and DuPont SORONA bicomponent fully stretched polyester filaments, and further enhanced by special alkali-reduced and other dyeing and finishing processes. This not only gives it a gradually emerging blue and white vertical stripe texture in appearance, but also makes it more skin-friendly and dry to the touch, comfortable and warm when worn close to the skin. In addition, it also has functions such as moisture absorption and breathability, antibacterial and odor suppression, and resistance to snagging, pilling and fuzzing. The production method preferably uses DuPont SORONA bicomponent fully stretched polyester FDY filaments interwoven with 40S microporous blended functional fiber yarns, and the preparation process is simple.

[0005] To achieve the above objectives, the solution of the present invention is:

[0006] A single-layer alkali-reducing, lightweight, quick-drying, antibacterial weft-knitted fabric is provided. The single-layer alkali-reducing, lightweight, quick-drying, antibacterial weft-knitted fabric is made of 40S microporous blended yarn and 50D / 36F DuPont SORONA bicomponent fully stretched polyester FDY filament. The yarn weight ratio of the 40S microporous blended yarn to the 50D / 36F DuPont SORONA bicomponent fully stretched polyester FDY filament is 70%-74%:26%-30%.

[0007] The single-layer effect alkali-reduced, lightweight, quick-drying, antibacterial weft-knitted fabric is made of a front loop layer and a back loop layer interwoven and stacked. The front loop layer is composed of 40S microporous blended yarn, and the back loop layer is composed of 50D / 36F DuPont SORONA bicomponent fully stretched polyester FDY filament. The 40S microporous blended yarn covers the 50D / 36F DuPont SORONA bicomponent fully stretched polyester FDY filament, and the front loop layer and back loop layer are interwoven through a knitting process to form a plain weave.

[0008] The single-layer effect alkali reduction lightweight quick-drying antibacterial weft-knitted fabric forms a single-layer two-color alternating vertical stripe appearance.

[0009] The 40S microporous blended yarn is made of a blend of polyester, cotton and modal fibers, with a weight ratio of polyester, cotton and modal of 50%:25%:25%.

[0010] The fabric body is composed of a horizontal row of plain weft single-sided knit layer in a cyclic configuration, and the single-sided knit is configured with alternating single-needle loop formation and sinker-assisted loop release.

[0011] The single-layer effect alkali-reduced lightweight quick-drying antibacterial weft-knitted fabric has a weight per square meter of 145-150 g / m². 2 .

[0012] A method for producing a single-layer alkali-reducing, lightweight, quick-drying, antibacterial weft-knitted fabric includes a knitting process and a dyeing and finishing process, wherein the knitting process uses the following knitting method:

[0013] The fabric is knitted using a 28-needle 30-inch single-sided circular knitting machine with a single-sided weft configuration featuring 4 needle tracks, a sinker track, and a single-sided weft needle for loop removal. The minimum cycle of a complete structure of the single-layer effect alkali-reduced, lightweight, quick-drying, and antibacterial weft-knitted fabric is 1 warp row × 1 row, where: the warp row is formed by 4 needle tracks, 1 needle track, and 1 sinker track for loop removal; the row is formed by 1 loop-forming system around the needle track.

[0014] In this system, the arrangement of a single needle in a complete structure is designated as A, where A represents a high-heel needle. The yarn threading method of a single looping system in a complete structure is as follows: 40S microporous blended yarn (with a ratio of 50% polyester, 25% cotton, and 25% modal) is threaded through the upper hole of the yarn guide, and 50D / 36F DuPont SORONA bicomponent fully stretched polyester FDY filament is threaded through the lower hole of the yarn guide. The yarns in the upper and lower holes work simultaneously, and the face yarn covers the base yarn to form an interwoven structure.

[0015] Table 1 shows the triangle and yarn threading configuration for a complete fabric:

[0016]

[0017] The yarn configuration corresponds to: 1 indicates 40S microporous blended yarn (the proportions are: polyester 50%, cotton 25%, modal 25%), and 2 indicates 50D / 36F DuPont SORONA bicomponent fully stretched polyester FDY filament.
