Description

Technical Field

[0001] The invention relates to the technical field of textile production, in particular to a moisture-absorbing quick-drying fabric and a manufacturing process thereof. Background Art

[0002] In the hot summer, people sweat easily. Outdoor workers, such as traffic police on duty, construction workers, outdoor athletes, outdoor enthusiasts, etc., all hope that the clothes they wear are loose, breathable, light and cool. Even if the clothes are soaked with sweat, they hope that they can be dried quickly by the wind, so that they will not stick to the body, affect comfort, and cause harm to skin health.

[0003] At present, in view of the characteristics of summer clothing, there are some quick-drying fabrics on the market, which can quickly dry clothes after washing. However, the ingredients of some of these fabrics cannot quickly absorb moisture on the human body surface, and have low perspiration efficiency, making them stuffy to wear. They do not have the ability to dry quickly, protect against the sun or cool down, and they stick to the body when exposed to water, so they are not comfortable to wear. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a moisture-absorbing and quick-drying fabric and a manufacturing process to achieve rapid moisture absorption and perspiration release, good air permeability, skin-friendly and smooth, and comfortable and crisp wearing effects.

[0005] To achieve the above-mentioned invention object, the present invention adopts the following technical scheme: a moisture-absorbing quick-drying fabric, which is composed of regenerated cellulose fiber, flax fiber and special-section polyester filament fiber, the weight percentage of regenerated cellulose fiber in the fabric is 20-30%, the weight percentage of flax fiber is 20-30%, and the weight percentage of special-section polyester filament fiber is 40-60%; the fabric is a twill fabric.

[0006] Furthermore, the regenerated cellulose fiber is at least one of lyocell fiber, bamboo fiber, viscose fiber and modal fiber.

[0007] Furthermore, the polyester filament fibers with special-shaped cross-sections are irregular fiber filaments of cross shape, island shape, honeycomb shape, dumbbell shape, and four-leaf shape, and the filament fineness is between 40D and 75D.

[0008] Furthermore, the warp yarn number of the fabric is 18.2-9.7 tex, the weft yarn number is 18.2-14.5 tex, and the total weight of the fabric is 100-160 g / m 2 , preferably 120 to 150 g / m 2 .

[0009] A process for producing a moisture-absorbing and quick-drying fabric comprises the following steps:

[0010] (1) Warp production: sliver preparation, flax fiber and regenerated cellulose fiber are mixed in a ratio of 60:40, and before the cotton cleaning process, they are evenly mixed and then slotted in the disc grabber of the cotton opener. After the cotton cleaning process, the cotton rolls are made into cotton rolls with a dry weight of 360 g / m and a length of 30 m. Since flax fiber has poor cohesion and is easily broken, the process principle of light quantitative, heavy pressure and light blow is adopted; the cotton rolls are fed into the carding machine, the dry weight of the sliver is 18 g / 5 m, the cylinder speed is 260 rpm, the needle speed ratio is 2.0, and the carding adopts the process principle of soft carding and slow speed;

[0011] In the roughing process, the raw sliver is mixed in three passes on the drawing frame, the rough yarn is 4.0 g / 10m, the twist coefficient is 89, and the process principle of heavy pressure and slow speed is adopted;

[0012] In the spinning and winding process, 40D filaments are used to spin on the spun filament core-spun yarn device, and the filament tension coefficient is 1.2 times. The filaments introduced by the godet and the roving whiskers drawn in the back area enter the front roller jaws for drawing, and the filaments are in the center of the whiskers. The yarn number is 18.2-9.7 tex, and the twist coefficient is 380.

[0013] (2) Production of weft yarn: Preparation of raw sliver: flax fiber and regenerated cellulose fiber are mixed in a ratio of 40:60. After being evenly mixed before the cotton cleaning process, they are placed in a slot on the disc grabber of the cotton opener and then go through the cotton cleaning process to make cotton rolls. The dry weight of the cotton rolls is 380 g / m and the length is 30 m. Since flax fiber has poor cohesion and is easily broken, the process principle of light quantitative, heavy pressure and light blow is adopted; the cotton rolls are fed into the carding machine, the dry weight of the raw sliver is 16 g / 5 m, the cylinder speed is 280 rpm, the needle speed ratio is 2.0, and the carding adopts the process principle of soft carding and slow speed;

[0014] In the rough drawing process, the raw sliver 1 and raw sliver 2 are mixed according to the blending ratio, and the rough yarn is drawn by three steps, the rough yarn is 4.0 g / 10m, the twist coefficient is 82, and the process principle of heavy pressure and slow speed is adopted;

[0015] The spun yarn adopts compact spinning, the spun yarn number is 18.2-14.5 tex, and the twist coefficient is 390;

[0016] Yarn doubling, combining the spun yarn with two strands of 75D heterosexual cross-section polyester filament to form weft yarn;

[0017] (3) Fabric production: Fabric specification 98x53 2 / 1 right twill fabric, width 153 cm, warp yarn is warped in batches, the total number of warp roots is 9500 during warping, and the tension of each warp beam is controlled during warping to ensure uniform tension of the warp beam; reeding process: the number of ground weave insertions is 2, the number of side weave insertions is 3, 32 threads are inserted on each side, and the side weave insertions are: 1,1,2,2 (3 insertions); weaving adopts 2 / 1 twill weave.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: ① The special-shaped cross-section polyester filament fiber makes the fabric have an excellent capillary effect, quickly absorbs the moisture of the inner layer and guides it to the outer layer of the fabric, making the fabric cool and transparent. ② The flax fiber makes the fabric have moisture absorption and perspiration wicking properties. Flax has good moisture absorption and can quickly absorb sweat and moisture from the inner layer. It also has excellent moisture conductivity and can quickly discharge the absorbed moisture into the atmosphere, making the user feel comfortable. ③ The interwoven fabric of filament and staple fabric has the gloss and wrinkle resistance of filament fabric, which has strong protection, and also reflects the softness and comfort of staple fiber.

[0019] The present invention discloses a moisture-absorbing quick-drying fabric and a manufacturing process thereof. The main components are flax fiber and special-shaped cross-section polyester filaments, which can quickly absorb moisture and discharge sweat, have a large water absorption capacity, good stiffness, and will not stick to the body. The regenerated cellulose has the characteristics of good moisture absorption and softness, smoothness, and skin-friendliness. The manufacturing method is simple, simple and efficient. The fabric is a practical moisture-absorbing quick-drying clothing product for outdoor workers in summer. BRIEF DESCRIPTION OF THE DRAWINGS
