Special size composition for sizing hank yarns

Abstract

The invention provides a special size composition for sizing hank yarns and application thereof and belongs to a hank yarn fiber spinning finishing agent. The special size composition is prepared from the following raw materials in part by weight: 50 to 60 weight parts of corn starch, 10 to 20 weight parts of polyvinyl alcohol, 10 to 15 weight parts of polyacrylic acid, 8 to 10 weight parts of sized yarn smooth paste, 3 to 6 weight parts of grease EL, 1 to 2 weight parts of DDF catalyst, 0 to 15 weight parts of bone glue, 1 to 2 weight parts of antistatic agent and a proper amount of water. The invention provides an ideal special size composition for sizing hank yarns, which has high yield, excellent yarn separability, low end breakage rate, no strip sticking nor sizing spot, and easy and complete de-sizing. As less polyvinyl alcohol (PVA) in adopted in formula, the ideal special size composition for sizing hank yarns is environment-friendly, diversified and suitable for small-batch production and can be mastered flexibly and operated conveniently. The composition of the invention solves the technical problem that no special size composition for sizing hank yarns exists in the prior art.

Description

technical field [0001] The invention relates to a sizing composition specially used for sizing skeins and an application thereof, which belongs to a skein fiber textile treatment agent. Background technique [0002] Skeined yarn is used for many varieties of designs and colors demanded by the market, leno fabric weaving and hand-knitting and embroidery techniques with different twisting methods, twist numbers, counts, different materials and many indicators of strength. There are many varieties and batches of skein yarn products Small, complex yarn count, especially for yarn-dyed polyester-cotton blended (T / C) and cotton (C) hank yarns, good sizing quality before weaving, complete desizing before dyeing, for yarn-dyed weaving Product quality is of the utmost importance. [0003] In the prior art, there is no special sizing material suitable for hank yarn sizing. Using other existing traditional sizing materials has low sizing rate, poor yarn separation, high end-breakage ra...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there is no special sizing material suitable for hank yarn sizing. Using other existing traditional sizing materials has low sizing rate, poor yarn separation, high end-breakage rate, and sticky streaks and sizing spots. , desizing is not complete, a large amount of non-biodegradable polyvinyl alcohol (PVA) is used in the formula, desizing is discharged, and the environment is polluted
