Problems solved by technology

As a result, the water molecules and vapor molecules of the fabric are difficult to discharge or absorb through the fibers. Generally, the air permeability is 280mm / s, and the moisture permeability is 7000g / m 2 .d or so, and poor elastic recovery, easy to wrinkle, poor hand feeling and drapability
Wearing it as a shirt or underwear fabric is dull, airtight and uncomfortable
These problems have always restricted the popularization and application of fabrics.
[0004] The amino silicone oil used in the normal variety is a diamine type structure. Because the amino group in the molecule is very polar, it is easy to combine with the hydroxyl group, carboxyl group, and amido group on the fiber to form a stable silicone film. The film makes the fabric show various hand properties such as softness, smoothness, crispness, plumpness, and flexibility, but it blocks the passage of water molecules and vapor molecules, and reduces the performance of weaving and moisture absorption and perspiration. Such softeners cannot be used

Embodiment Construction

[0023] Dyeing and finishing methods of cotton high-count and high-density fabrics:

[0024] 1. Singeing:

[0025] High-count and high-density fabrics have a large amount of sizing, and the hairiness is closely attached. It is difficult to burn off the hairiness during singeing. This invention adopts four pairs of steel wire brushes, brushing the front and back sides, and is equipped with copper roller singeing to implement contact singeing. , to ensure the quality of singeing.

[0026] Process flooding process: gray cloth→turning the seam head→two positive and two reverse bristles→two positive and two reverse four burner singeing→copper roller singeing→steam fire extinguishing

[0027] Flame temperature: 1200~1300℃

[0028] Speed: 80~85m / min

[0029] 2. Cold stack:

[0030] Technological process: Rolling working liquid → coiling → rotating and stacking for 24 hours

[0031] Working pressure: NaOH: 50-55g / L

[0032] Scouring agent: 5g / L

[0033] Chelating age...

Abstract

The invention discloses a method for dyeing and finishing pure-cotton high-count high-density fabric, which includes steps of singeing, cold dome, desizing and boiling-off, bleaching, mercerization, dyeing, moisture absorption and breath, no-iron sorting, tentering, pre-shrinking and packaging. The fabric dyed and finished by the present invention has advantages of high rebound, moisture absorption and breath, crease-resistance and soft feel.

Description

technical field [0001] The invention relates to a method for dyeing and finishing cotton high-count and high-density fabrics. Background technique [0002] With the improvement of living conditions, people have higher requirements for clothing. From the original pursuit of beauty, two new concepts of comfort and environmental protection have been added, thus putting forward higher requirements for the chemical indicators of fabrics. , and high-count and high-density fabrics are mostly used as shirts or underwear fabrics, which are in direct contact with human skin, so this problem is even more important. [0003] Cotton high-count and high-density fabrics have a delicate and smooth appearance, and are relatively high-end clothing fabrics. The weave structure of cotton high-count and high-density poplin is a plain weave fabric, with the most interweaving points among all fabrics. In addition, high-count yarns have low strength. When sizing yarns in textile mills, a large amo...
