Description
Technical Field
The invention relates to pantyhose, in particular to a pair of pantyhose with moisture absorption, heating and warm keeping functions.
Background
In recent years, the continuous emergence of novel fiber materials provides a new development space for textiles, the wearability of the textiles is continuously improved, the material culture life of people is greatly enriched, and the fashionable requirements of people on the innovation, high quality and personalized expression of the use value of the textiles are met. At present, functional fibers in novel fiber materials are developed rapidly, and the production scale of novel fiber products such as sea-island fibers, profiled cross-section fibers and the like is expanded; biofunctional fibers, chitin fibers and the like are also beginning to be marketed; in addition, a batch of new fiber varieties with originality and independent intellectual property rights, such as silkworm pupa protein fibers, polylactic acid fibers developed based on starch and the like, are successfully researched and developed, and are put into batch production, so that the varieties of fiber raw materials are enriched.
Thirteen five textile industry scientific and technological concerns and industrialization projects (knitting) are provided, and the application of novel raw materials such as differential fibers and high-performance fibers in high-grade knitted fabrics is developed. The technology is a knitted product development technology which adopts natural fibers with special functions or differential and functional fibers (such as fibers with the functions of resisting bacteria, absorbing moisture, releasing sweat, keeping warm, negative ions, far infrared, resisting ultraviolet, hollow fibers, cross-section fibers and the like) and combines a knitting weaving technology to realize the functionalization of a knitted product.
Along with the trend of fashion and the pursuit of comfort, novel textile thermal insulation materials are more and more favored by people, along with the advance of society and the improvement of living standard of people, the requirement of people on comfort can not be met only by adding or subtracting the thickness of clothes, the fabric capable of adjusting the temperature becomes higher pursuit, a series of thermal insulation function clothes products are produced, and the development of pantyhose with high moisture absorption, heating and thermal insulation functions has very good economic benefit and market prospect.
At present, domestic research on thermal insulation textiles mainly focuses on the aspects of spinning processes and development of knitted fabrics, for example, moisture absorption heating fibers and modal fibers are blended, then the blended yarns and nylon-spandex core-spun yarns are used as raw materials to develop and produce knitted thermal underwear, and a set of production processes of spinning, weaving and dyeing and finishing is explored.
The invention discloses an Outmass air-conditioning fiber as a phase-change heat-storage temperature-regulating material, which is characterized in that a certain medium (considering that the phase-change temperature is within a certain range) is added in county committee, and the phase-change characteristic of the medium is utilized to ensure that the temperature of textiles is kept unchanged when the medium absorbs or emits heat. The novel touch functional fiber, namely the softwar fiber, developed by Dongli corporation in Japan combines the advantages of the special artificial wood pulp fiber and the differential acrylic fiber, has the characteristics of heating, warm keeping and soft touch, and the softwar fiber absorbs moisture emitted by human skin and converts the moisture into heat energy through chemical reaction to realize heating. EKS fibers developed by eastern jersey have a temperature and humidity control function, and are obtained by introducing hydrophilic groups such as amino groups and carboxyl groups into polyacrylic acid molecules and performing crosslinking treatment, and the EKS have moisture absorption capacity 3.5 times that of cotton and moisture absorption calorific value about 2 quilts of wool and down, and are widely used in underwear for women, bedding cotton, sportswear, ski shirts and the like.
In conclusion, the development of the novel moisture-absorbing and heating fiber and the application product of the clothing and apparel thereof has important significance for improving the added value of the textile, and is one of the important subjects which are researched and developed by scholars at home and abroad and enterprises for a period of time in the future.
Disclosure of Invention
