Problems solved by technology

Its shortcomings are: ①. The sizing procedure is more complicated, which brings difficulties to the operation, and there are also fluctuations in the quality of the size caused by human factors, which is not conducive to the stability of the quality of the sizing in actual production.
②. Due to the poor biodegradability of PVA, the desizing wastewater will pollute the environment
③. The amount of PVA in the traditional denim size formula is 5-10%. The average price of PVA in 2008 is about 17,000 yuan per ton, which is relatively expensive.

Embodiment 1

[0022] Embodiment 1: The ratio of components in parts by weight is: 72 parts of oxidized starch, 20 parts of acetate starch, 3 parts of polyacrylic size, and 5 parts of wax flakes. This size is suitable for denim fabrics with a warp of 32 counts.

Embodiment 2

[0023] Embodiment 2: The ratio of components in parts by weight is: 82 parts of oxidized starch, 10 parts of acetate starch, 3 parts of polyacrylic size, and 5 parts of wax flakes. This size is suitable for denim with 7 warp yarns.

Embodiment 3

[0024] Example 3: The ratio of components in parts by weight is: 77 parts of oxidized starch, 15 parts of acetate starch, 3 parts of polyacrylic size, and 5 parts of wax flakes. This size is suitable for denim fabrics with 21 warp yarns.

[0025] The invention discloses a method for preparing an environment-friendly denim special combined size, which comprises sequentially adding oxidized starch, acetate starch, polyacrylic acid type size, and wax flakes into a mixing tank, and mixing evenly to obtain a finished product.

Abstract

The invention relates to a environment-friendly type denim special combined sizing agent used or sizing on the 7-32 warp threads for weaving denim, which comprises polyacrylic acids sizing agent, wax pieces, oxidized starch and acetic ester starch, according to the weight proportion of: oxidized starch 72-82 parts, acetic ester starch 10-20 parts, polyacrylic acids sizing agent 3 parts and wax pieces 5 parts. The method for preparing the sizing agent in the invention is: adding the oxidized starch, acetic ester starch, polyacrylic acids sizing agent and wax pieces into a mixing pot in order; mixing uniformly and obtaining the finished product. The invention replaces the PVA in prior art formula by acetic ester starch, consequently, achieves the advantages of environmental protection, reduce cost, easy preparation and stable quality.

Description

technical field [0001] The invention relates to a combined size used for sizing denim warp yarns, in particular to a combined size used for denim warp yarns in the range of 7 to 32 counts, ring yarn, slub yarn and the like. Background technique [0002] Textile warp sizing is a complex project, usually using multi-component size formulations. Existing denim special size, its component comprises starch, polyvinyl alcohol PVA, polyacrylic size and wax sheet. Its disadvantages are: ①. The sizing procedure is more complicated, which brings difficulties to the operation, and there are also fluctuations in the quality of the slurry caused by human factors, which is not conducive to the stability of the quality of the sizing in actual production. ②. Due to the poor biodegradability of PVA, the desizing wastewater pollutes the environment. ③. The amount of PVA in the traditional denim size formula is 5-10%. The average price of PVA in 2008 is about 17,000 yuan per ton, which is re...
