Technical Field

The invention relates to the field of fabrics, in particular to a heating velvet seamless underwear formed by cutting and sewing heating velvet seamless fabrics.

Background

In the clothing industry, the wearing requirements are not only warm keeping, covering and fashionable and attractive, but also great changes in requirements have occurred in the field of textile clothing nowadays, the changes in requirements bring new research and development guidance to product design, and through market research and sales data analysis in the past year, the wearing requirements of users for underwear in autumn and winter gradually lean towards the directions of 'softness', 'comfort', 'high elasticity', 'light and thin heating'.

Because a large amount of chemical reagents are needed in the process of adding special chemical components, potential safety hazards exist when people wear the underwear in a body-attached mode, energy conservation and emission reduction are not facilitated, the process flow is complex, the price of the underwear is always high, and the development and popularization of the underwear with the moisture absorption and heating functions are limited. How to choose a healthy, comfortable and really high-cost performance thermal underwear is an urgent requirement for consumers. On the other hand, in the design of clothes, the warm-keeping effect is achieved by increasing the thickness, such as local patch warm-keeping, multilayer thickened warm-keeping and the like. This bulky design increases the inconvenience of human mobility.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings. The terms "inner" and "outer" are used to refer to directions toward and away from, respectively, the geometric center of a particular component.

The heating velvet seamless underwear provided by the invention is formed by cutting and sewing heating velvet seamless fabric as shown in figure 1; the heating velvet traceless fabric comprises a warm-keeping layer 100, a fleece layer 110 is formed on the inner surface of the warm-keeping layer 100, a blocking layer 200 is arranged on the outer surface of the warm-keeping layer 100, and the blocking layer 200 and the warm-keeping layer 100 are connected through spandex filaments 320.

It can be understood that the warm-keeping layer 100 is used for storing hot warm air and reducing the loss of heat emitted by a human body to the outside, the blocking layer 200 is used for reducing the loss of the hot warm air in the warm-keeping layer 100 to the outside so as to improve the warm-keeping effect of the fabric, the blocking layer 200 and the warm-keeping layer 100 are connected through the spandex filament 320, so that the fabric can have higher longitudinal and transverse elasticity, when the garment is worn, the garment can bend over and bend over freely without tearing feeling, and the fabric can be enabled to have no trace and no filament drop.

In order to improve the heat preservation effect of the fabric, a heating fabric is adopted, as shown in fig. 2, the heat preservation layer 100 is knitted by at least two heat preservation woven yarns 300, the heat preservation woven yarns 300 comprise a core layer 330 and an outer covering layer, the outer covering layer comprises viscose fibers 310 and spandex filaments 320, and the viscose fibers 310 and the spandex filaments 320 are wound outside the core layer 330 in a Z shape; the core layer 330 includes long staple cotton fibers 331 and aerogel particles 332.

The viscose fibers 310 are high in hygroscopicity, more human body water vapor is absorbed by the high-hygroscopicity viscose fibers 310, water molecules moving at high speed are captured, kinetic energy is converted into heat energy to release heat, and the heat energy is moisture absorption and heat emission; the fluffy densely covered micropore in aerogel granule 332's inside, aerogel granule 332 can lock hot warm air, because air thermal conductivity is not strong, remains the hot warm air in aerogel granule 332 inside, can improve the heat accumulation effect of surface fabric. On the other hand, on the yarn structure, the outer cladding layer comprises viscose fibers 310 and spandex filaments 320, and the viscose fibers 310 and the spandex filaments 320 are wound outside the core layer 330 in a Z shape; the core layer 330 comprises a fabric woven by the yarn structure of the long stapled cotton fibers 331 and the aerogel particles 332, and is more fluffy and thicker under the same gram weight, and can store heat and keep warm.

The fineness of the viscose 310 can influence the heat storage and warm keeping effects of the viscose on the warm-keeping woven yarn 300 core layer 330, so that the fineness of the viscose 310 is 0.9D-1.2D, and preferably, the fineness of the viscose 310 is 1.1D.

As shown in fig. 3, the barrier layer 200 needs to reduce convection between the inside of the garment and the outside so as to further reduce the dissipation of heat emitted by the human body to the outside, the barrier layer 200 is knitted by at least two barrier woven yarns 400, and the barrier woven yarns 400 are formed by blending bulked acrylic fibers 410 and viscose fibers 310 by siro spinning.

The bulk acrylic fiber 410 has the characteristic of swelling after thermal contraction, when the thermal insulation layer 100 is heated by human heat conduction, because the barrier layer 200 is directly contacted with the thermal insulation layer 100, the bulk acrylic fiber 410 in the barrier layer 200 swells after thermal contraction, and the heat loss is blocked to block the heat loss and the thermal air loss in the thermal insulation layer 100. The ratio of the bulk acrylic fiber 410 to the viscose fiber 310 in the barrier woven yarn 400 is 35: 65.

the fineness of the bulk acrylic fiber 410 is 0.8D-1.0D.

The fleece layer 110 includes a plurality of spaced fleece regions 111.

Those of ordinary skill in the art will understand that: the above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents, improvements and the like made within the spirit of the present invention should be included in the scope of the present invention.
