Description

Technical Field

[0001] The invention relates to a unidirectional moisture-conducting, ultra-fast-drying and sweat-removing yarn and a processing method and application thereof, belonging to the technical field of textile clothing processing. Background Art

[0002] Unidirectional moisture-conducting fabrics are the preferred choice for making sportswear. Unidirectional moisture-conducting means that water can only be transferred from one side of the fabric to the other side through absorption, diffusion and evaporation, and cannot be transferred reversely. The transfer is directional. This performance is mainly affected by two aspects: one is the difference in yarn hydrophilicity. The hydrophilicity of the yarns on both sides of the fabric is different, which makes the water move to the hydrophilic yarn, that is, the wetting gradient effect; the second is the change in fabric structure. The water uses the difference in the size of the pores in the fabric to transfer to one side of the small pores, that is, the differential capillary effect. At present, there are some problems in the practical application of unidirectional moisture-conducting fabrics. First, the moisture-conducting performance of this type of fabric is often not ideal, and it is impossible to quickly conduct sweat from the skin surface to the outer layer of the fabric in a short time, causing the wearer to feel wet and uncomfortable during exercise or high temperature environment; this type of fabric also has certain defects in durability. After multiple washings, the moisture-conducting and breathable properties may decrease significantly, affecting its service life. Finally, some chemical additives may be used in the production process of unidirectional moisture-conducting fabrics. These additives may cause potential harm to human health or the environment and need further research and improvement.

[0003] Therefore, it is very important to research and invent a unidirectional moisture-conducting yarn and fabric with good moisture-conducting performance, easy manufacturing and processing, high wearing comfort and good performance. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the one-way moisture-conducting fabric has the problems of poor moisture-conducting and perspiration-releasing effect, short service life, poor wearing comfort, etc. in practical application.

[0005] In order to solve the above problems, the present invention provides a unidirectional moisture-conducting, ultra-fast-drying, sweat-removing yarn, which includes a core yarn and a hydrophilic layer on its outer layer; the core yarn is made of a special-section polyester fiber, and the hydrophilic layer is a modified special-section wool blended yarn. The hydrophilic layer has the property of quickly absorbing moisture from the body surface, directing the moisture to the hydrophilic layer, and keeping itself dry. The moisture is locked into the core layer to prevent the moisture from diffusing, and the moisture is directed into the core layer by using the differential capillary effect. The core layer has the property of gathering moisture and quickly conducting the moisture out.

[0006] Preferably, the hydrophilic layer is made of descaled fine wool yarn, the raw material of which is fine wool with a fineness of 64-70 counts.

[0007] Preferably, the polyester fiber with a special-shaped cross section is a honeycomb microporous modified polyester, a triangular cross-section polyester fiber, a cross-section polyester fiber or a wavy cross-section fiber.

[0008] Preferably, the polyester fiber with a special-shaped cross-section is a filament with a linear density of 85-160 dtex and a special-shaped degree of more than 15%.

[0009] The present invention also provides a method for processing the above-mentioned unidirectional moisture-conducting, ultra-fast-drying and sweat-removing yarn: arranging the polyester fibers with special cross-sections in parallel into fiber bundles; cleaning and opening the wool blended yarn, performing a descaling modification treatment, and then spirally winding it around the fiber bundle in a Z-twist manner to form a hydrophilic layer.

[0010] Preferably, the descaling and modification treatment uses a protease to perform the modification and descaling treatment.

[0011] Preferably, the twist degree of the fiber bundle is less than 15 twists / m.

[0012] Preferably, the wrapping spinning twist number of the wool blended yarn outside the fiber bundle is 300-500 twists / m.

[0013] The present invention also provides an application of the above-mentioned unidirectional moisture-conducting, ultra-fast-drying and sweat-removing yarn: the yarn is combined with any non-hydrophilic yarn to produce a fabric by a double-sided weaving method, and the unidirectional moisture-conducting performance of the fabric is achieved through post-finishing, thereby obtaining a unidirectional moisture-conducting, ultra-fast-drying and sweat-removing fabric.

[0014] Preferably, the surface layer of the fabric is subjected to a hydrophobic finishing, and the inner layer is subjected to a hydrophilic finishing, so that the inner layer in contact with the body surface can quickly absorb sweat, and conduct it to the edge of the fabric through the unidirectional moisture conduction performance of the yarn, and the sweat can be shaken out through exercise. Among them, the method of hydrophilic finishing and hydrophobic finishing of the inner layer and the outer layer is to integrate hydrophilic or hydrophobic additives on the surface, the hydrophilic additives include nano zeolite, hydrophilic silicone oil, polyether modified silicone oil, silicone finishing agent, etc., and the hydrophobic additives include inorganic nanomaterials such as SiO 2 , ZnO, TiO 2 And organic siloxane, etc.

[0015] The principle of the present invention is to design a sheath-core structure yarn. The sheath layer uses hydrophilic fibers with excellent moisture absorption effect to quickly absorb water and keep the contact surface dry. The core layer uses special-shaped cross-section fibers to quickly gather the moisture absorbed by the sheath layer and transmit it to the end of the yarn through various groove cavities. Double-sided fabrics woven with this yarn and non-hydrophilic yarns, and hydrophilic and hydrophobic treatments on both sides, can obtain a fabric with excellent moisture absorption and perspiration removal effects.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. It has a better moisture absorption and perspiration-releasing effect: the water absorption of the polyester fiber with a special cross section used in the present invention can be increased by about 20% compared with the ordinary polyester fiber. The grooves on the surface of the fiber with a special cross section and the cavity inside facilitate the accumulation and drainage of moisture.

[0018] 2. Expand the application field of one-way moisture-conducting clothing: Common one-way moisture-conducting clothing on the market generally has a light and cool feeling as a common feature. The one-way moisture-conducting yarn provided by the present invention uses wool fiber as the outer layer, which has a softer and warmer touch than other one-way moisture-conducting yarns, and is more suitable for sports scenes in lower temperatures.

[0019] 3. Simple manufacturing and convenient steps: The steps for preparing a unidirectional moisture-conducting yarn provided by the present invention are simple, the structure is simple, and it is suitable for mass production. BRIEF DESCRIPTION OF THE DRAWINGS
