However, as a weaving yarn, wormwood fiber has poor weaving performance, and its development and application are not perfect enough. The sizing process is an important way to improve the weaving performance of wormwood fiber and the quality of its functional fabrics, but the existing sizing formula Most of them are refractory components, which not only have a very limited effect on improving the performance of wormwood fibers, but also cause environmental problems
For example, although PVA, acrylic, and starch are the three mainstream sizing materials in the current sizing market, they are difficult to apply to wormwood fiber, and among them, PVA is not biodegradable, which has caused environmental problems and is bound to be replaced. OK; the traditional acrylic size has severe re-viscosity, which makes it difficult to split; while the starch-based size fluctuates greatly in viscosity and poor pasting performance

Embodiment 1
[0030] Embodiment one: pulp raw material characteristic and its effect in the present invention
[0031] Oxidized starch: Almost all oxidants can oxidize starch. Compared with acid-thinned starch, oxidized starch also reduces the molecular weight, and also has the characteristics of high concentration and low viscosity; the temperature of paste formation is reduced, and the highest thermal viscosity is also reduced; more importantly The characteristic is that due to the addition of anionic genes in the molecule, the stability of the starch paste is greatly improved, the debasing is small, the transparency is high, and the adhesion is strong. In addition, oxidized starch has good film-forming properties and high film strength, which is beneficial to sizing; the increased water solubility of starch is beneficial to the preparation of size and desizing.
[0032] CD-DF868M: solid powder, white or light yellow powder. CD-DF868M replaces PVA sizing, the dry splitting resistance of ...
Embodiment 2
[0039] Embodiment two: a kind of wormwood / cotton blended yarn size
[0040] It is composed of 1.5% oxidized starch, 6% CD-DF868M, 1.5% corn starch, 1% solid acrylic acid; 0.5% glycerol as an auxiliary agent, 1% 2-naphthol, and 0.5% wax flakes.
[0041] The total solid content of the slurry is 12%, and the dry weight of the total slurry is 24g.
Embodiment 3
[0042] Embodiment three: a kind of wormwood / cotton blended yarn size
[0043] It is composed of 6% oxidized starch, 1.5% CD-DF868M, 1.5% corn starch, 1% solid acrylic acid; 0.5% glycerin as auxiliary agent, 1% 2-naphthol, and 0.5% wax flakes.
[0044] The total solid content of the slurry is 12%, and the dry weight of the total slurry is 24g.

Abstract
The invention discloses a wormwood / cotton blending yarn slurry and preparation and application thereof, and aims to develop a biodegradable high-quality slurry with low price to improve product performance, increase a product variety and simultaneously reduce the technical problem of environment pollution. The slurry is prepared from oxidized starch, CD-DF868M, corn starch, solid acrylic acid, glycerinum, 2-naphthol and wax. The slurry is applied to the wormwood / cotton blending yarn to carry out sizing processing to further detect a sizing effect. The slurry adopted by the wormwood / cotton blending yarn can replace PVA (Polyvinyl Acetate) for sizing, and the strength and elongation, the abrasive resistance, the anti-flexion performance and the flexibility of a slurry membrane after sizing can be greatly improved; in addition, the wormwood / cotton blending yarn slurry has the advantages of low price, environment protection and good economic benefit and social benefit and can be used for the production of a fine count high density variety, and the production requirement of high speed, high efficiency and high quality can be met.
Description
technical field [0001] The invention relates to the technical field of textiles, in particular to a wormwood / cotton blended yarn size and its preparation and application. Background technique [0002] With the progress of society, people's living standards are also improving, and correspondingly, the requirements for wearing are getting higher and higher. It is not only required that the clothing should have good warmth retention and comfort, but also that the clothing should be green and environmentally friendly. It has become a trend to apply the research results of functional fibers to daily life. The uninterrupted development and utilization of new fibers save a lot of energy such as oil and reduce environmental pollution. Natural fibers have a better affinity to the human body, and some natural fibers have the effect of medical care. With the advancement of science and technology and the improvement of living standards, people's pursuit of returning to nature and no c...
