Problems solved by technology

However, because wicker is a pure natural plant fiber, it is not resistant to humidity and drying, resulting in reduced mechanical properties, easy mildew and fracture, and poor bearing capacity, which restricts the further development of products. If wicker is pretreated before weaving, it will improve Its adaptability to the external environment improves the mechanical properties, so that the quality of willow products will be greatly improved

Embodiment

[0011] The pretreatment agent of this embodiment is prepared from the following raw materials in parts by weight (kg): 0.1 hydrophilic silicone oil, 0.2 secondary alkyl sodium sulfonate, 0.3 nanocrystalline cellulose, 12 silica sol with a solid content of 20%, ascorbic acid Sodium 0.01, clarified lime water 7, polyethylene oxide 1.5, water 45.

[0012] The preparation method of present embodiment treatment agent is:

[0013] (1) First put sodium secondary alkyl sulfonate and sodium ascorbate into water, stir to dissolve the materials completely, then heat the mixed solution to 40-50°C, then add polyethylene oxide, stir and mix for 35 minutes, and the obtained solution is ready for use;

[0014] (2) Slowly add clarified lime water to the silica sol drop by drop, and keep stirring. After the dropwise addition, add nano-microcrystalline cellulose into the mixed solution, and ultrasonically disperse it evenly. The solution and other remaining materials are completely mixed evenly...

Abstract

The invention relates to the technical field of wicker modified treatment, in particular to a nano-microcrystalline cellulose-silica sol reinforced pretreating agent for willow weaving wickers and a preparation method thereof. The nano-microcrystalline cellulose-silica sol reinforced pretreating agent is composed of, by weight, 0.1-0.2 part of hydrophilic silicone oil, 0.1-0.2 part of secondary alkane sulphonate sodium, 0.2-0.4 part of nano-microcrystalline cellulose, 10-12 parts of silica sol with the solid content being 20-25%, 0.01-0.02 part of sodium ascorbate, 6-8 part of clear limewater, 1-2 parts of polyoxyethylene and 40-50 parts of water. After the pretreating agent permeates into the wickers, the functions of strengthening, toughening, plasticity improvement and the like are achieved; the clear limewater has the functions of assisting materials to be attached and bonded to fibers and the like; the modified wickers are better in weaving performance, smooth, pliable, tough and capable of achieving more high temperature resistance; products woven by the pretreated wickers are longer in service life, increase weight capacity and further widen the service range.

Description

technical field [0001] The invention relates to the technical field of wicker modification treatment for wicker, in particular to a nano-microcrystalline cellulose-silica sol reinforced pretreatment agent for wicker for wicker and a preparation method thereof. Background technique [0002] Willow weaving is one of the traditional folk handicrafts in China. In ancient times, it was only used as an ordinary daily practical product. It did not rise until the last few decades of the 20th century. It has gradually become an item for exporting foreign exchange in some parts of China. One of the large willow production bases. [0003] Wicker, as the material of wicker, can be woven into various simple and natural, beautiful, light and durable practical handicrafts through novel design. With the continuous development of the industry and the continuous innovation of products, there will be more novel, practical and beautiful willow products displayed in front of customers. However...
