Description

Technical Field

[0001] The invention relates to a moisture-absorbing, breathable and flat-wrapped soft-stretch hexagonal fabric and an application and a preparation method thereof, belonging to the technical field of functional textile materials. Background Art

[0002] With the improvement of people's living standards and the pursuit of a healthy lifestyle, the demand for functional fabrics is increasing. Among the many demands, moisture absorption, breathability and smooth wrapping are important development directions for modern clothing fabrics. For example, in the field of sportswear, good moisture absorption and breathability can effectively absorb sweat discharged from the human body, keep the skin dry, and avoid stuffiness and discomfort caused by sweat accumulation. In addition, the smooth wrapping of fabrics can provide better fit for the wearer, reduce friction between clothing and skin, and improve wearing comfort.

[0003] However, existing fabric technology still has some shortcomings in achieving moisture absorption, breathability and a smooth wrapping feel. For example, although some fabrics have good moisture absorption, they have poor breathability, resulting in a noticeable feeling of stuffiness when worn. Other fabrics, although they have good breathability, perform poorly in terms of moisture absorption and perspiration, and cannot meet the needs of the human body during exercise or in high temperature environments. In addition, while pursuing softness and comfort, some fabrics often sacrifice elasticity and smoothness, resulting in a lack of support when worn.

[0004] In order to overcome these shortcomings, a variety of composite fabrics and functional fiber fabrics have been attempted on the market. For example, fabrics with multi-layer structure design can achieve multiple functions such as moisture absorption, breathability and warmth retention through the fiber characteristics of different layers. However, the preparation process of these fabrics is often more complicated, and in actual use, the bonding strength and functional stability between the layers still need to be further optimized.

[0005] Therefore, developing a soft and elastic hexagonal fabric that is both moisture-absorbent and breathable and flat is of great significance to meet the high-performance requirements of modern clothing and home textile fabrics. This fabric should be able to effectively absorb and dissipate human sweat while providing good elasticity and fit to meet the needs of various wearing and use scenarios such as sports, leisure, and sleep. Summary of the invention

[0048] Second embodiment:

[0049] A method for preparing a finished product of a moisture-absorbing, breathable and flat-wrapped soft-elastic Liumeiji fabric comprises the following steps: The soft elastic six-layer fabric with both moisture absorption, breathability and flat wrapping prepared in Example 1 is dyed to obtain a finished soft elastic six-layer fabric with both moisture absorption, breathability and flat wrapping feeling; Among them, the dyeing process is as follows: Unwinding, flat-width ultrasonic washing, pre-setting, dyeing, dehydration, drying, setting, and finished products; Dyeing is divided into two steps, first dyeing with disperse dyes (specific process as Figure 3 ), and then dyeing with reactive dyes (specific process such as Figure 4 ); The pre-setting temperature is 180℃, the machine speed is 25m / min, the frame is 10 knots; the air volume (up / down) is 100%, the overfeed is 40%, and the dosage of auxiliary degreasing agent is 2%; The setting temperature is 130℃, the machine speed is 30m / s, the frame is 86 inches, the air volume (up / down) is 80%, the overfeed is 12%, and the amount of auxiliary softener is 5%; Hydrophilic softeners and moisture wicking aids are added during dyeing and when the finished product is set; anti-phenol yellowing aids are added when the finished product is set.

[0050] The obtained soft and stretchy Liumeiji fabric with both moisture absorption, breathability and flat wrapping was subjected to performance testing, and the test results are as follows: Table 1 performance Test Results Pilling performance Level 3-4 Pilling performance after 2000 frictions Level 3-4 Snagging performance 3-4 vertical levels, 4 horizontal levels Tensile elastic elongation (%) Vertical 38.0 Horizontal 83.0 Tensile elastic recovery rate (%) test Vertical 85.1 Horizontal 81.6 <![CDATA[Water vapor permeability ((g / (m 2 ·24 h))]]> <![CDATA[1.01×10 4 ]]> Air permeability (mm / s) 636 (coefficient of variation: 2.4%) Anti-wrinkle performance (grade) Level 4 <![CDATA[Cool touch coefficient (J / (cm 2 ·S)]]> 0.21 (average of 5 groups) Wear resistance (10,000 revolutions) (front) ＞10000 Static voltage half-life Static voltage (kv) 0.76 Static voltage half-life (s) 0.052 Excellent antistatic performance Washing performance (dimensional change) No abnormal changes in samples after washing Dimensional change after washing (%) Vertical -1.1 Horizontal -0.3 (- indicates contraction, + indicates extension) Appearance smoothness after washing and drying (grade) 4 .

[0051] Comparative Example 1: The surface needs to be skin-friendly and delicate to improve the touch of the fabric; omitting the first yarn will result in a less delicate feel; The secondary surface layer uses spandex to improve the vertical and horizontal elasticity of the fabric, which is suitable for different products; the second yarn is omitted, and the elasticity of the fabric decreases; The surface layer uses polyester filaments to improve the anti-snagging performance of the fabric, improve the quick-drying performance of the fabric, and increase the overall thickness of the fabric. The third yarn is omitted, and the anti-snagging performance decreases; The secondary lining uses polyester filaments to improve the fabric's anti-snagging performance, improve the fabric's quick-drying performance, and increase the overall thickness of the fabric. The fifth yarn is omitted, and the anti-snagging performance decreases; The inner layer uses spandex to improve the vertical and horizontal elasticity of the fabric, which is suitable for different products; if the sixth yarn is omitted, the elasticity of the fabric will decrease.

[0052] Comparative Example 2: The first, second and third yarns are all made of 80-nein Eukosil / Modal compact spinning yarn, which cannot be woven, and lacks pilling resistance and strength, and the bottom is exposed; Both routes 5 and 6 use semi-dull polyester filaments, and the fabrics lack elasticity.

[0053] Comparative Example 3: The first, second and third yarns are woven together, the fabric has poor anti-snagging performance, and the fabric cannot form an air layer, and cannot achieve a good breathable effect; The 5th and 6th weaves are combined, the fabric is not thick enough, the three-dimensional effect is insufficient, and the breathability will be worse.

[0054] Although the present invention has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
