Description

Technical Field

[0001] This invention belongs to the field of functional yarn-dyed fabric technology, specifically relating to a moisture-wicking, quick-drying, high-elastic fabric for iced coffee and its processing method. Background Technology

[0002] Cotton Tencel fabric combines the moisture-wicking and breathability of cotton with the smooth and delicate feel of Tencel, making it a widely used fabric in daily life. However, its moisture-wicking performance is poor. When the body sweats heavily, cotton Tencel fabric absorbs sweat to the point of saturation but cannot quickly wick it away, causing the damp fabric to stick to the skin and increase discomfort. Therefore, there is a need to develop a new type of clothing fabric that combines the comfort of cotton Tencel with rapid sweat wicking and durable performance to meet people's needs in conditions such as outdoor commuting.

[0003] When the human body sweats a little, the sweat enters the inner surface of the fabric in the form of liquid water through direct contact, and is conducted through the pores and capillaries between the yarn and fibers, and evaporates in the outer layer. The methods to make the fabric absorb water and dry quickly are: (1) Introduce moisture-wicking fibers or yarns with hollow structure and cross-shaped cross section, which have a faster water conduction speed than ordinary polyester due to the improvement of capillary effect. However, due to the presence of grooves and gaps on the fiber, the absorbed water is mechanically stored in the fiber, and the moisture release is not as good as ordinary polyester. At the same time, dust will be deposited in the grooves and pores on the fiber surface, and the water absorption and drying durability is not good. (2) Multi-layer composite fabric, which uses hydrophilic fibers as the inner layer structure of the fabric, conducts water from the gaps of the outer fabric to the outside, and achieves comfortable and cool performance. The moisture-wicking and quick-drying fabric described in patent CN222946346U consists of a moisture-wicking layer and a breathable layer. The moisture-wicking layer is made of a yarn made of cross-shaped polyester fibers wrapped with multi-strand yarn formed by twisting Tencel fibers and silver ion antibacterial fibers, interwoven with yarn spun from bamboo charcoal fibers. The breathable layer is made of yarn woven from twisted linen fibers and cashmere fibers. The inner moisture-wicking layer absorbs sweat and conducts it to the outer layer, while the outer breathable layer has several breathable holes to facilitate rapid drying. However, such multi-layered fabrics are prone to separation after repeated washing, and the fabric processing technology is complex. In addition, such double or multi-layered fabrics are generally thicker and heavier, which contradicts the demand for lightweight fabrics in summer. (3) Specific structural design. The inner surface of the fabric is provided with guide grooves, dot matrix protrusions, etc. to enhance the wicking effect and moisture conduction. However, this structure is prone to physical wear, collapse, and deformation after repeated wear and mechanical washing. Once the micro-geometric structure of the fabric surface is damaged, the capillary effect will be significantly weakened. (4) Water-absorbing and quick-drying finishing technology. This type of water-absorbing and quick-drying fabric, which is only finished with finishing agents, has insufficient durability, and at the same time, the hand feel becomes stiff and the breathability becomes worse. Moreover, most finishing agents only solve the problem of moisture absorption or quick drying, and have limited effect on promoting the rapid diffusion and evaporation of moisture, resulting in unbalanced finishing performance. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an iced coffee moisture-wicking, quick-drying, high-elastic fabric. This fabric combines iced coffee yarn with a cross-linking and setting process, leveraging the elasticity of the fabric to achieve superior moisture-wicking and quick-drying properties compared to ordinary woven fabrics. The fabric combines elasticity, coolness, and dryness, and also offers a comfortable feel. This invention also provides its processing method.

[0005] The iced coffee moisture-wicking, quick-drying, high-elastic fabric of the present invention comprises a cotton / Tencel / iced coffee yarn-dyed fabric woven from cotton / Tencel blended yarn and iced coffee elastic yarn, and the yarn-dyed fabric is obtained after being treated with modified polyurethane elastomer and bio-based non-organic silicone dispersion.

[0006] Preferably, the iced coffee elastic yarn is made by wrapping spandex yarn with iced coffee fiber, and the iced coffee fiber is ICEKAFE. ® Iced coffee fiber, available in one of the following specifications: 50D / 48F, 75D / 72F, or 100D / 96F; The modified polyurethane elastomer is TANA. ® PUR ONE, Shanghai Tuona Chemical New Materials Co., Ltd.; Bio-based non-organosilicon dispersion is MOOV AND COOL COMFORT NTL, Devan Chemicals NV.

[0007] Preferably, the cotton / Tencel blended yarn has a yarn count of 30-80 English single yarn or 60-160 English ply yarn, and the blending ratio of the cotton / Tencel blended yarn is one of 80 / 20, 70 / 30, 50 / 50, or 60 / 40.

[0008] Preferably, the fabric structure of the high-elastic fabric is one or a combination of several structures, including plain weave, twill weave, satin weave, striped weave, crepe weave, openwork weave, jacquard weave, and raised stripe weave.

[0009] The processing method of the moisture-wicking, quick-drying, high-elasticity fabric for iced coffee according to the present invention includes the following steps: (1) Fabric design: The fabric process design is carried out based on the yarn count and fabric structure; (2) Yarn dyeing: Dyeing of cotton / Tencel blended yarn and iced coffee yarn in packages; (3) Preparation of iced coffee elastic yarn: iced coffee yarn is wrapped with spandex yarn to prepare iced coffee elastic yarn; (4) Weaving: The cotton / Tencel blended yarn obtained in step (2) and the iced coffee elastic yarn obtained in step (3) are warped and sized, and woven according to the process design in step (1) to obtain the yarn-dyed fabric. (5) Finishing: The yarn-dyed fabric obtained in step (4) is desized, dry-set, stretched and pre-shrinked to obtain the finished fabric.

[0010] Preferably, in step (2), the cotton / Tencel blended yarn is dyed with reactive dyes at a temperature of 60-70℃; the iced coffee yarn is dyed with disperse dyes at a temperature of 120-140℃; and the dyeing time is 20-50 min.

[0011] Preferably, in step (5), desizing is performed using an enzyme, with an enzyme dosage of 10-40 g / L, a temperature of 80-95℃, and a machine speed of 70-100 m / min. The preferred enzyme is DS-HT desizing enzyme, manufactured by Zibo Lurui Fine Chemical Co., Ltd.

[0012] Preferably, in step (5), the desized fabric is dry-set at a temperature of 180-195℃ and a speed of 20-30m / min; the dry-set fabric is then stretched and set by padding with finishing liquid at a rate of 60%-70%, a temperature of 150-170℃, and a speed of 20-50m / min.

[0013] Preferably, the finishing solution has the following composition: Modified polyurethane elastomer TANA ® PUR ONE, 20-40g / L Bio-based non-organosilicon dispersion MOOV AND COOL COMFORT NTL, 20-30 g / L The rest is water.

[0014] Preferably, in step (5), the stretched fabric is pre-shrunken, the machine speed is 20-70m / min, and the rubber blanket temperature is 100-130℃.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Using polyester as a carrier, iced coffee yarn, which incorporates nano-sized mica particles and coffee grounds nanoparticles, gives the fabric a cool and dry feel.

[0016] 2. Based on the cotton / Tencel fabric, the weft yarn is replaced with iced coffee elastic yarn. The hygroscopicity of the iced coffee fiber itself and the high porosity of the elastic yarn help to absorb the moisture absorbed by the cotton / Tencel yarn, forming a synergistic effect of "cotton moisture absorption + iced coffee moisture wicking", improving the fabric's quick-drying efficiency, preventing sweat retention, and keeping the skin dry.

[0017] 3. In the finishing process, polyether polyurethane elastomers are used to seal some of the hydroxyl groups of cotton / Tencel, preventing water molecules from penetrating deep into the cotton / Tencel fibers, so as to achieve the purpose of absorbing water but not locking it in; bio-based non-organosilicon additives introduce water-based groups based on natural ingredients into the fabric, improving the moisture management ability of the fabric surface; the synergistic effect of the two further improves the moisture absorption and quick-drying performance of the fabric.

[0018] 4. The iced coffee elastic yarn creates a highly elastic fabric. Repeated stretching does not easily damage the yarn structure, ensuring functional stability during dynamic wear and solving the needs of moisture absorption without sticking to the body and quick-drying for a more refreshing feel.

[0065] Table 1. Test Results of Examples and Comparative Examples

[0066] Based on the indicators of the various embodiments in Table 1, the fabric of this invention exhibits good overall moisture absorption and quick-drying properties. The warp uses cotton / Tencel, and the weft uses iced coffee, achieving a synergistic effect of "cotton absorbing moisture + iced coffee wicking moisture," thus improving the fabric's quick-drying efficiency. Simultaneously, the selected finishing agent TANA... ® The combination of PUR ONE and MOOV forms cross-links on cotton / Tencel fibers, locking in some of the hydrophilic groups and preventing water molecules from penetrating deeper into the fibers. This also improves surface moisture management, further enhancing the fabric's absorbency and quick-drying properties. Comparative Example 1 shows that fabrics with both warp and weft made of cotton / Tencel have a long absorption time, possibly due to the added finishing agents, resulting in a low evaporation rate and a long time for absorbed water to evaporate. Comparative Example 2 shows that if cotton / Tencel is interwoven with ordinary polyester, although the absorption time is long, the evaporation rate is faster. Even with hydrophilic finishing agents, the weft wicking of ordinary polyester is not very high. Comparative Examples 3 and 4 show that, compared to TANA... ® PUR ONE and MOOV can improve the surface hydrophilicity of fabrics, increasing absorbency and wicking height, while TANA... ® PUR ONE seals the hydroxyl groups of cotton Tencel fibers during the stretching and setting process, preventing water from being absorbed into the fiber interior and only wetting the fiber surface. This results in slightly slower water absorption but slightly faster evaporation rate for the fabric.
