Problems solved by technology

[0002] Starch is a natural polymer compound with abundant resources, inexhaustible supply and good adhesion. It is commonly used in the textile industry as a treatment agent and sizing agent for yarn and fabric. The sizing process can Make the fibers stick to each other, increase the breaking strength and grinding ability of the yarn, can withstand various mechanical forces in weaving, and reduce fluffing and broken ends, but the original starch paste has high viscosity and poor fluidity, and there is "regression". Ther...

Embodiment 1

[0020] The indicators are: ash content% ≤ 0.44, the thickness has passed CQZO, water content ≤ 13.8, gluten strength ≥ 23.8, and the wheat heart powder flour with normal smell weighs 85kg, and stirs it evenly in a kneader at room temperature; weigh the crosslinking agent The amount of 0.5% is mixed with flour spray evenly. The above cross-linking agents can choose one or more of the following types: acrylic esters, cross-linking agents, adhesives, DE, EH, MH, acrylic polyesters, copolymers For hot-melt adhesive, self-crosslinking chain 7601, etc., if several components are selected, the ratio between them can be determined according to the situation, but the amount of the final cross-linking agent formulated remains unchanged at 0.5%; the cross-linking agent After mixing evenly with the flour spray, you can weigh 3% of penetrating agents, 1.4% of fatifying agents, 2.5% of dispersants, and 1% of stabilizers , 5% for smoothing agents, 0.6% for accelerators, 1% for slurries, and ...

Embodiment 2

[0023] The formula and proportion of phospholipid cross-linked starch are as follows: Weigh the super powder flour whose index is: pass Q / 320682RGW01-2004 standard, ash content%≤0.45, qualified thickness, moisture%≤13.7, normal smell, gluten strength≥27 The required amount is 92kg, and stir evenly in a kneader at room temperature; weigh 1% of the cross-linking agent and mix it with flour spray evenly. The above cross-linking agent can choose one or more of the following types: acrylate Class, cross-linking agent, adhesive, DE, EH, MH, acrylic polyester, copolymerized hot-melt adhesive, self-cross-linking 7601, etc., if several components are selected, the ratio between them can be determined according to the situation, but The amount of the final cross-linking agents formulated remains unchanged at 1%; after the cross-linking agents are evenly mixed with the flour spray, 2% of the penetrating agents can be weighed, and 1% of the lipidifying agents can be weighed. Amount of 1% ...

Embodiment 3

[0025] The formula and proportion of phospholipid cross-linked starch are as follows: Weigh the special flour with index ash %: ≤0.85, gluten %≥25, thickness: CB30 and CB36<10%, moisture %≤14, normal smell 86.9kg, stir evenly in the kneader at room temperature; weigh 0.5% of the cross-linking agent, mix it with flour spray, the above cross-linking agent can choose one or more of the following types: acrylate, cross-linking Chain agent, adhesive, DE, EH, MH, acrylic polyester, copolymerized hot-melt adhesive, self-crosslinking chain 7601, etc., if several components are selected, the ratio of each other can be determined according to the situation, but the final formulation The amount of the cross-linking agent is 0.5% unchanged; after the cross-linking agent is mixed with the flour spray evenly, the penetrating agent can be weighed in an amount of 1%, the fatifying agent can be weighed in an amount of 1.3%, and the dispersant can be weighed Weigh 2.1% of the amount, 0.7% of th...

Abstract

The invention discloses phosphate ester crosslinked starch and a production method thereof. The production method is as follows: wheat flour, a crosslinking agent, a penetrant, an esterifying agent, a dispersant, a stabilizer, a smoothing agent, an accelerant, an antistatic agent, an antifoaming agent, an antiseptical agent and slurry are weighed and directly and uniformly stirred in a kneader according to certain quantity, and a mixture obtained is weighed and packaged. As for selection of various raw materials, more than one raw material can be selected, and the composition effect of three to five raw materials is optimum. The content of the starch is correspondingly adjusted according to the ash and the biceps of the raw materials and various raw starch varieties such as wheat in different areas; the grade requirement of the slurry can be optimally adjusted according to the customer requirements; parameters of ten agent varieties are subjected to corresponding mechanical adjustment according to difference of finished products of the raw materials, etc., and lowest cost and optimum quality in any grade are realized; and the customer requirements on different varieties of sized yarns and slurry can be met by increase or reduction of the agent varieties.

Description

technical field [0001] The invention relates to a phospholipid crosslinked starch and a production method thereof. Background technique [0002] Starch is a natural polymer compound with abundant resources, inexhaustible supply and good adhesion. It is commonly used in the textile industry as a treatment agent and sizing agent for yarn and fabric. The sizing process can Make the fibers stick to each other, increase the breaking strength and grinding ability of the yarn, can withstand various mechanical forces in weaving, and reduce fluffing and broken ends, but the original starch paste has high viscosity and poor fluidity, and there is "regression". Therefore, its application is greatly limited, and the quality of the starch used is not stable enough, the batch difference is large, and the quality of sizing is not good or bad. [0003] In the traditional modified starch production process, strong alkali swelling, strong acid neutralization, and water washing are used, whic...
