Description
Technical Field
The invention relates to the technical field of textiles, in particular to a moisture-absorbing and sweat-releasing yarn, a preparation method and application.
Background
Under the working environment of hot summer or high temperature, a human body can discharge a large amount of sweat, at the moment, if the worn clothes are not breathable, the sweat cannot be discharged quickly, the surface of the human body can generate sultry discomfort, but the effect of ventilation and perspiration of general clothes is obtained by dyeing and finishing the fabric finished by weaving, so that along with the improvement of life quality, the requirements of people on the comfort, health, safety, environmental protection and the like of the fabric of the clothes are higher and higher, along with the increase of outdoor activity time of people, the trend that casual clothes and sportswear permeate and are integrated into a whole is increasingly favored by consumers, the fabric of the clothes not only requires good comfort, but also requires that once sweat flows down to the back, the clothes can not be pasted with the skin to generate cold and wet feeling. The cotton fabric has better moisture absorption and air permeability, so the cotton fabric is usually preferred for the garment fabric, but the moisture diffusion speed is low, the fibers transversely swell after absorbing a large amount of moisture, gaps among yarns are closed, sweat and moisture cannot diffuse outwards, the fabric is moist and hot, and the fabric is easy to stick to the skin, so the cold and wet feeling is brought to the human body. The common polyester fiber has poor moisture absorption and air permeability due to the hydrophobic characteristic of the common polyester fiber, and is easy to generate stuffiness feeling.
The yarn is a textile processed by various textile fibers into a certain fineness, can be used for weaving, rope making, thread making, knitting, embroidery and the like, and can be generally divided into staple fiber yarn, continuous filament yarn and the like. The yarn includes pure yarn and blended yarn according to the raw material classification of the yarn, and the pure yarn is yarn spun by a fiber material, such as cotton yarn, wool yarn, hemp yarn, silk yarn and the like. Such yarns are suitable for making pure woven fabrics; the blended yarn is yarn spun by two or more fibers, such as blended yarn of terylene and cotton, blended yarn of wool and viscose, and the like, and the yarn is used for fabrics for highlighting the advantages of the two fibers. The yarn includes thick, medium, thin and extra-thin yarns according to the yarn thickness, and the thick yarn is 32 tex or more (British 18 inches and less). Such yarns are suitable for thick fabrics, such as tweed, denim, and the like; the medium yarn refers to 21-32 tex (19-28 English count made by English) yarn. Such yarns are suitable for medium-thick fabrics, such as medium-flat cloths, gabardine, khaki, and the like; fine yarn refers to yarn of 11-20 tex (english 29-54 english). Such yarns are suitable for delicate fabrics, such as scrims, poplin, and the like; the extra fine yarn means a yarn of 10 tex or less (58 english count or more). The yarn is suitable for high-grade fine fabrics, such as high-count shirts, worsted next-to-skin woollens and the like.
The traditional yarn process can not meet the functional requirements of consumers, but some chemical fibers such as terylene can well increase the added value of the existing products. For example, after the fiber is modified, sweat can be rapidly transferred to the surface of the fabric and diffused by the action of absorption, diffusion, transmission and the like of the sweat through the capillary phenomenon generated by the micro-grooves on the surface of the fiber, so that the aim and the action of moisture conduction and quick drying are achieved, but the modified fiber only has the functions of moisture absorption and sweat release, does not have the advantages of strong heat insulation, good comfort, difficult wrinkling, soft hand feeling and the like, and is limited in use range.
In order to solve the problems, the invention provides a moisture-absorbing and sweat-releasing yarn.
