Embodiment 1

[0046] Reactive dyeing of short cotton fibers: ① pre-treatment (mixing cotton, refining, bleaching); ② then use reactive dyes, dyeing at 45 ~ 75 ℃ continuous heating; ③ post-treatment process (soaping, color fixing), Then, the cotton staple fibers obtained by dyeing above were blended with undyed cotton staple fibers (10:90) to obtain 32 cotton color-spun yarns.

[0047] Then with the above-mentioned made cotton color spinning yarn, the cross section polyester of 75D, 70D spandex according to the ratio of 45%, 50%, 5%, adopt such as figure 1 Weaving according to the weave diagram to obtain gray cloth, then performing soft resin finishing, and setting at 180°C to obtain the knitted elastic fabric of the present invention.

[0048] The elongation of the obtained fabric is 49% in the longitudinal direction and 31% in the transverse direction; the elongation recovery rate is 68% in the longitudinal direction and 70% in the transverse direction; the water absorption is within 1s, a...

Embodiment 2

[0050] The blending ratio of the dyed cotton staple fiber to the undyed cotton staple fiber is 60:40, and the rest is the same as in Example 1 to obtain 21 counts of all-cotton color-spun yarn.

[0051] Then with the above-mentioned made cotton colored spinning yarn, 75D cross / circular section polyester, 70D spandex according to the ratio of 60%, 30%, 10%, adopt such as figure 2 Weaving according to the weave diagram to obtain a gray cloth, and then performing soft resin finishing and setting at 190° C. to obtain the knitted elastic fabric of the present invention.

[0052] The elongation of the obtained fabric is 68% in the longitudinal direction and 41% in the transverse direction; the elongation recovery rate is 71% in the longitudinal direction and 73% in the transverse direction; the water absorption is 3s, and the residual moisture rate is 35.2% after 1 hour; the washing color fastness is Grade 4-5, the dry rubbing fastness is 4-5, and the wet rubbing fastness is 3-4. ...

Embodiment 3

[0054] The blending ratio of the dyed cotton staple fiber to the undyed polyester staple fiber is 90:10 and the rest is the same as in Example 1 to obtain 21 counts of cotton / polyester colored spun yarn.

[0055] Then the above-mentioned cotton / polyester color spun yarn, 75D cross-section polyester, 70D spandex are used according to the ratio of 65%, 30%, 5%, such as figure 1 Weaving according to the weave diagram to obtain gray cloth, and then performing soft resin finishing, setting at 185°C to obtain the knitted elastic fabric of the present invention.

[0056] The elongation of the obtained fabric is 51% in the longitudinal direction and 38% in the transverse direction; the elongation recovery rate is 69% in the longitudinal direction and 70% in the transverse direction; the water absorption is 3s, and the residual moisture rate after 1 hour is 38.9%; the color fastness to washing is Grade 4, the dry rubbing fastness is grade 4-5, and the wet rubbing fastness is grade 3.

Abstract

The invention discloses a knitting elastic fabric, a production method and purposes. The elastic fabric is a single-surfaced or double-surfaced weft knitting fabric formed by colored spun yarns, modified cross-section terylene and spandex. A fabric surface layer is weaved by cotton-fiber colored spun yarns; a base layer of the fabric is weaved by colored spun yarns, modified cross-section terylene and spandex; the content of the colored spun yarns is 45 to 65%; the content of the modified cross-section terylene long filaments is 30 to 50%; and the content of the spandex is 5 to 20%. The fabric has rich surface color and high color fastenss; and the knitting elastic fabric can be manufactured into elastic pants.

Description

technical field [0001] The invention relates to a knitted elastic fabric, in particular to a knitted elastic fabric with a mixed color effect on the surface. Background technique [0002] At present, the colored knitted elastic tights sold on the market generally use the method of piece dyeing, and the woven primary color gray cloth is put into a dyeing vat for dyeing to obtain knitted fabrics of different colors. After the resulting fabric is made into clothes, the color is monotonous. Such as patent document CN103628241A discloses a kind of knitted fabric, adopts polyester staple fiber, cotton fiber and spandex as raw material, and fish scale and its change structure are weaved to form gray cloth, then carry out processing including dyeing to obtain product, although gained fabric has excellent cotton feel, It is light and fluffy and has good water absorption and quick-drying functions, but it uses piece dyeing method, which has the problem of color difference between cot...
