Technical Field

The invention belongs to the technical field of knitted fabric preparation, and particularly relates to a red bean velvet light, thin and soft type heating functional fabric.

Background

In recent years, the development of various thermal underwear on the market and the requirements of people on lightness, thinness, warmness and comfort promote the updating and upgrading of novel thermal underwear. However, the traditional heating fabric mostly adopts the increase of the gram weight and the thickness of the fabric to improve the warmth retention property, the fabric is thick and uncomfortable to wear next to the skin, and particularly, the fabric is easy to generate overstaffed and uncomfortable feeling when being used as the fabric of underwear next to the skin, so that the application of the heating function on the light and thin fabric is greatly restricted. The multifunctional fabric with the performances of moisture absorption, heat generation and the like is not seen in the market at present due to the large processing difficulty, and has a certain development value.

Disclosure of Invention

The invention aims to solve the problems and provides a red bean velvet light, thin and soft heating functional fabric which is light, thin, comfortable, good in heat preservation performance and capable of absorbing moisture and heating.

In order to solve the technical problems, the invention adopts the following technical scheme: the red bean velvet light, thin and soft heating functional fabric is woven on a double-sided weft knitting machine with the gauge of 24 needles/inch or 28 needles/inch, an upper dial and a lower needle cylinder of the double-sided weft knitting machine are fully lined with needles, knitting needles of the upper dial are alternately arranged by an upper dial low needle and an upper dial high needle, knitting needles of the lower needle cylinder are alternately arranged by a lower needle cylinder low needle and a lower needle cylinder high needle, and the fabric is woven by adopting the following method:

the first path of yarn is looped with the high needle of the upper dial, looped with the low needle of the upper dial, not looped with the low needle of the lower needle cylinder, not looped with the high needle of the lower needle cylinder, and lined with spandex to form loops together;

the second path of yarn is tucked with the high needles of the upper dial, is not looped with the low needles of the upper dial, and is tucked with the low needles of the lower cylinder and the high needles of the lower cylinder;

the third path of yarn is not looped with the lower needle of the upper dial and the high needle of the upper dial, is looped with the high needle of the lower needle cylinder and the low needle of the lower needle cylinder, and is looped together with fusible spandex;

the fourth path of yarn is not looped with the high needle of the upper dial, is not looped with the low needle of the upper dial, is looped with the low needle of the lower needle cylinder, is looped with the high needle of the lower needle cylinder, and is looped together with spandex;

the fifth path of yarn is tucked with the lower needle of the upper dial, is not looped with the high needle of the upper dial, and is tucked with the high needle of the lower needle cylinder and is tucked with the lower needle of the lower needle cylinder;

the sixth path of yarn is not looped with the lower needle of the upper dial and the high needle of the upper dial, is looped with the high needle of the lower needle cylinder and the low needle of the lower needle cylinder, and is looped together with spandex;

the seventh path to the twelfth path repeat the weaving method of the first path to the sixth path, and the six paths are taken as a cycle and are repeated in cycles to obtain the grey cloth of the knitted fabric;

and carrying out double-sided napping treatment on the knitted fabric grey cloth on a napping machine, and carrying out shearing and ironing finishing on the napped and finished fabric to obtain the red bean velvet light, thin and soft heating functional fabric.

The speed of the napping machine is 14.5-26m/min, the clockwise rotation speed is 200-359r/min, the anticlockwise rotation speed is 200-359r/min, and the large cylinder rotation speed is 32-50 r/min.

The first path, the third path, the fourth path and the sixth path of yarns adopt pure bulked acrylic yarns or blended yarns containing bulked acrylic yarns, and the percentage of acrylic fibers in the blended yarns is 10-90%.

And the second path of yarn and the fifth path of yarn adopt 20D or 30D spandex.

The bulk acrylic fibers are nano titanium dioxide modified acrylic fibers, the modified acrylic fibers are prepared by blending and spinning nano titanium dioxide and an acrylic fiber spinning solution, and the fiber fineness is 0.9-1.1D.

Compared with the prior art, the invention has the following advantages:

the red bean velvet light, thin and soft type heating functional fabric prepared by the invention is light and thin in texture and is woven by a double-sided weft knitting machine, the second path and the fifth path are connected by spandex in the weaving process, and a large heat insulation air layer is formed in the middle of the weave, so that the weaving method is more favorable for improving the heat retention property of the fabric, improving the temperature rise value of moisture absorption and heating, and preventing the loss of heat, and simultaneously increasing the light, thin and soft characteristics of the fabric, all indexes of the fabric reach the GB/T30127-2013 standard requirements, the highest moisture absorption and heating temperature rise value reaches 7 ℃ and the average temperature rise value reaches 3.5 ℃ according to the national detection standard FZ/T73036-2010 detection standard.
