Embodiment

[0051] An energy-saving and environment-friendly slurry for cotton and man-made cellulose fibers. The main components are Fluorine / Serra, wax and water.

[0052] When the size is PVA-free, starch-free, fully substituted formula, as shown in Table 1.

[0053] Table 1

[0054]

[0055] According to different yarn counts, the total warp number is constant.

[0056] When the slurry is PVA-free, semi-substituted formula, as shown in Table 2.

[0057] Table 2

[0058]

[0059]

[0060] According to different yarn counts, the total warp number is constant.

[0061] Wherein, the starch is selected from native starch or modified starch (such as CMS modified starch). The wax is emulsified oil-1.

[0062] The application of the above-mentioned energy-saving and environment-friendly size is applied to the sizing process. The sizing process includes the sizing process and the desizing process; Sizing, after injecting into the size tank, the method of single size tank sizing;...

Abstract

The invention relates to energy-saving environment-friendly slurry for cotton and man-made cellulose fiber and application of the energy-saving and environment-friendly slurry. The energy-saving and environment-friendly slurry is combination slurry of Ferro Lyocell and does not contain PVA. Compared with the prior art, the invention can achieve an excellent sizing effect under the condition that the solid content is only about 25% of the traditional process starch and PVA / acrylic acid (conventional product), and the strength and elongation of single yarn can reach the traditional process level; no skinning phenomenon appears in the sizing process and the dry separation is smooth; no slurry falling happens in weaving and the weaving environment is clean and tidy; the residual slurry can be reused, and the viscosity is stable under the same temperature and same solid content; the subsequent desizing, scouring and bleaching process is simple, and the comprehensive sewage COD is reducedby about 50%; the desized slurry itself has a flocculation effect on the sewage, which is truly economical, efficient, energy-saving and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of textile pulp, and in particular relates to an energy-saving and environment-friendly pulp for cotton and artificial cellulose fibers. Background technique [0002] Textile size plays a pivotal role in textile mills, and various sizes and auxiliaries appear on the market. Starch (including modified starch), polyvinyl alcohol (PVA) and polyacrylic size are still the three main sizes. [0003] The shortcomings of raw starch used in warp yarn sizing are mainly due to the large molecular weight, poor fluidity and impregnation; easy to form pulp skin, generally under high temperature conditions (above 95°C); unstable viscosity; poor film-forming properties, poor flexibility, The glass transition temperature is high, the size film is hard and brittle; the adhesion to hydrophobic fibers is not enough, the coating size is large, and the size falls during weaving. [0004] The Achilles' heel of PVA is non-environ...
