Problems solved by technology

[0005] At present, low-temperature disperse dyes are used for dyeing corn fiber. The temperature is generally around 200°C, which will still damage the corn fiber, but the dyeing cannot be achieved at a lower temperature.

Embodiment 1

[0025] Corn fiber and cotton fiber with a length of about 36mm are blended according to a weight ratio of 1:1 to obtain a corn fiber / cotton blended fabric. The weaving mainly includes: opening and cleaning - carding - drawing - roving - spun yarn ——winding——warping——sizing——weaving; Sodium sulfonate 20-30wt%, sodium lauryl sulfate 3-5wt%, alkyl tertiary amine 2-3wt%, stearic acid amine 5-8wt%, water balance, sizing slurry is PVA-1799 slurry , Mechanical foaming, the foaming ratio is 15:1, the half-life is greater than 30min, and the sizing rate is controlled at 10-12%.

[0026] The dyeing and finishing process mainly includes weaving - scouring - bleaching - dyeing - finishing;

[0027] The woven corn fiber and cotton fiber are blended for scouring. The process: use NaOH 5-10g / L, high-efficiency refining agent KRD-1 1-2g / L, dispersing and chelating agent 1-2g / L, penetrating agent JFC 1g / L, detergent 2g / L, bath ratio 1:20, temperature 100°C, scouring time 40-60min, according...

Abstract

A dyeing and finishing process of a corn fiber / cotton blended fabric. The fabric is prepared from blended weaving of 50 wt.% of corn fiber and 50 wt.% of cotton fiber. The cotton fiber has main body length range of 30-40 mm; the dyeing and finishing process mainly includes weaving, boiling off, bleaching, dyeing and finishing; and the weaving process mainly includes opening picking, cotton carding, drawing, roving, spun yarn, spooling, beaming, slashing and weaving. After staining, the corn fiber and cotton fiber have good homochromatism, and strength damage of the fabric is reduced.

Description

[0001] technical field [0002] The invention relates to a fabric dyeing and finishing process, in particular to a dyeing and finishing process of a corn fiber / cotton blended fabric. Background technique [0003] Corn fiber is a kind of green fiber that is widely used now. In fact, the polylactic acid fiber made of corn, wheat and other starches, which is first fermented into lactic acid and then polymerized and melt-spun, is generally called corn fiber. . The fiber is biodegradable and will be converted into environmentally friendly carbon dioxide and water after being discarded, and the carbon dioxide and water can be converted into starch under photosynthesis, thereby realizing recycling. [0004] Corn fiber is soft and smooth, strong, moisture-absorbing and breathable. The processed products have silky luster and comfortable skin touch and feel, good drapability, good heat resistance and anti-ultraviolet function, and good wearability. Corn fiber is suitable for dyeing...
