Embodiment 1

[0037] Warp yarn: T / R / PU covered yarn, weft yarn: CD-PET / R / PU covered yarn, A / R / PU covered yarn; the arrangement ratio of the two kinds of weft yarns is 1:1; 2 / 2 is used Weaving the twill weave, the overall coverage factor of the obtained gray cloth is 2117, and the ratio of the warp and weft direction coverage factor of the gray cloth is 1:0.9, and then finishing and processing after dyeing to obtain the product.

[0038] Among them, T / R / PU covered yarn and CD-PET / R / PU covered yarn: firstly, polyester staple fiber or cationic dye dyeable polyester staple fiber and ordinary viscose staple fiber with round cross section are made by spinning process. 40S / 2 T / R or CD-PET / R composite yarn, and then respectively covered with 70D spandex to form T / R / PU covered yarn with a twist of 850T / M, CD-PET / R / PU covered yarn Covering yarn; A / R / PU covered yarn: First, through spinning process, acrylic staple fiber and viscose staple fiber are made into 40S / 2 A / R composite yarn, and then covered ...

Embodiment 2

[0048] Warp yarn: 40S T / R+40D spandex, in which the length of T / R staple fiber is 38mm, using polyester staple fiber, ordinary circular section viscose staple fiber and spandex to be directly spun into T / R / PU composite elastic core-spun yarn with a twist of 800T / M;

[0049] Weft yarn: 30S A / R+40D spandex, using ultra-fine acrylic staple fiber, viscose staple fiber and spandex to directly spin into A / R / PU core-spun yarn by ring spinning core-spun yarn technology. Wherein the single fiber fineness of acrylic staple fiber is 0.9D, and it accounts for 57% of the mass percentage of yarn, viscose staple fiber is a flat section, and it accounts for 38% of the mass percentage of yarn, and spandex accounts for 57% of the mass percentage of yarn. 5%;

[0050] Adopt plain weave weave to weave, gained gray cloth overall coverage coefficient is 1920, and gray cloth warp-weft direction coverage coefficient ratio is 1: 0.8; Dyeing and finishing processing technology: with embodiment 1;

...

Embodiment 3

[0054] Warp yarn: T / R / PU covered yarn and A / R / PU with a ratio of 2:1, weft yarn: T / R / PU covered yarn, in which the single fiber fineness of acrylic staple fiber is 0.9D, and the weave adopts 3 / 1 / 2 / 1 changes twill weaving, other processes are the same as embodiment 1, and the content of T / R / PU covered yarn in the obtained functional fabric is 89.4%, and the content of A / R / PU covered yarn is 10.6%; The fabric cover factor is 3800, the warp and weft cover factor ratio is 1:0.6, and the fabric hairiness cover value is 0.57mm.

[0055] Product performance: The warp elasticity of the fabric is 17.5%, the elastic recovery rate is 90.5%, the weft elasticity is 17%, and the elastic recovery rate is 91%. The standard product (T / R / PU) is 0.8 degrees higher than that; after the functional fabric of the present invention is made into a garment, when the indoor temperature is 22 degrees, in a quiet state, the actual temperature sense of the skin is 31.3 degrees, which is 31.3 degrees compa...

Abstract

The invention discloses a functional fabric as well as a production method and an application thereof. 50 to 90 percent by weight of yarns in the fabric are covering yarns or wrap yarns which are formed by terylene short fibers, mucilage glue short fibers and spandex fibers, and 10 to 50 percent by weight of yarns in the fabric are covering yarns or wrap yarns which are formed by ultrafine acrylic short fibers, flat-cross-section mucilage glue short fibers and spandex fibers; and the ratio of the warp coverage coefficient and the weft coverage coefficient of the fabric is 1: 0.6 to 1, and the clo value is more than 0.65. The functional fabric has an insulation function and an elastic function and is suitable for being made into coats worn in autumn and winter, and the wash-and-wear property of the coat which is made of the functional fabric is more than grade 3.5.

Description

technical field [0001] The invention relates to a functional textile, in particular to a warm and non-ironing elastic fabric as well as its production method and application. Background technique [0002] With the improvement of people's living standards, functional fabrics are becoming more and more popular. Functional fabrics currently on the market emerge in an endless stream to cater to the needs of consumers. [0003] Fabrics such as thermal insulation include the use of film, hollow or porous yarns, and special organizational structures. For example, in Chinese patent CN200810201054.9, it is disclosed that a water-soluble fiber is used as core yarn or accompanying spinning yarn, and cotton, wool, polyester or acrylic staple fiber is used as outsourcing fiber or intertwined fiber to wrap core-spun yarn or sirofil Weaving with Er yarn, and then dissolving the water-soluble fiber to form a hollow or porous fabric, but its washing and non-ironing effect is not good, and ...
