As an excellent textile material, the paper yarn can replace textiles which cause problems of allergic reaction of human bodies, environmental pollution and the like. Besides the advantages of the raw materials, for twisting and paper yarns, the hollow layer formed by twisting can greatly improve the heat preservation performance of the fabric, and in winter, when the paper yarn clothes are worn, the outer garment is sleeved to greatly improve the heat preservation effect. In addition, because of good air permeability, the clothing feels cool when worn in summer, and is comfortable clothing all the year round.
The raw paper for paper yarn (also called paper yarn raw paper) is made up by using plant fibre as main raw material, making it into paper under the specific condition, cutting it into paper strips, dyeing and twisting so as to obtain the invented paper yarn with different thickness for producing textile. At present, paper thread products in domestic market are mainly used for weaving various styles of colorful craft weaving paper for summer hats, fashion bags, disposable slippers, tatami, health mats and the like, and paper rope paper tape products such as paper braids, paper straw bags, colorful ropes and the like. The use requirement of the paper yarn base paper determines the quality requirement of the paper yarn base paper, and because the paper strips are subjected to the action of composite forces such as stretching, twisting and the like in the processes of cutting into narrow-width series of bobbin paper and rolling into paper wires after paper making, the base paper is required to have the characteristics of low ration, high strength and larger elongation.
In the prior art, paper yarn base paper is dyed, so that the color performance of the paper yarn base paper is reduced and the problem of large color difference is easy to occur in order to ensure the strength performance of the paper yarn base paper. Or when the color performance of the paper yarn base paper is ensured, the paper strength performance is sacrificed, including the problems of tensile property, tearing strength and elongation reduction of the paper yarn base paper.

Table 1 breaking strength test results of paper ropes
As shown in table 1, when the paper rope prepared in example 2 was compared with a pure paper rope on the market, the breaking strength of the paper rope finally obtained was improved by adding nanocellulose and plant cellulose and mixing them to prepare a paper yarn base paper. From the test results of the examples 1 and 2, it can be known that the breaking strength of the paper rope can be improved greatly by twisting and weaving the paper yarn and the polyester filament. From the test results of example 1 and example 3, it can be seen that the paper yarn and the polyester filament yarn are twisted and woven more optimally and have better strength than nylon filament yarn. As can be seen from the test results of the example 1 and the commercial paper yarn polyester cross-twisted product, the breaking strength of the paper rope made by cross-twisting and weaving is greatly improved.
Dry cleaning test:
the paper ropes prepared in the above examples were bound to a white cloth or a multi-fiber cloth at a distance of 5cm, and placed in a dry cup of 250ml of tetrachloroethylene and agitated for 30 minutes at a temperature of 30 c for two cycles, and the test results are shown in table 2.
And (3) water washing test:
3-5 paper ropes prepared in the above examples are sampled and nailed on the fabric. With reference to the ISO 6330-2012 standard, a front-mounted washing machine with 1000 ± 100 revolutions per minute (MIELE PW6065 fixed capacity) is used. The washing cloth is 100% polyester, and the area weight is 300 + -20 g/M 2 For a total of 4 layers, washing powder (tide) for household use was used. The washing method comprises the following steps: washing at 40 deg.C for 120 + -10 min, adding washing cloth 3.0 + -0.05 kg and household washing powder 30 + -1 g, washing for ten times, drum drying for one time, and drying at 80 deg.C for 90 + -10 min in a household dryer. The test results are shown in table 2.
TABLE 2 Dry and Water washing test results for paper cords
| Test sample | Dry cleaning | Washing with water |
| Example 1 | No obvious change of appearance color and no transfer dyeing | No obvious change of appearance color and no transfer dyeing |
| Example 2 | The appearance color is slightly lightened and slightly dyed | No obvious change of appearance color and no transfer dyeing |
| Example 3 | The appearance color is slightly lightened and slightly dyed | The appearance color is slightly lightened and slightly dyed |
| Paper rope product in market | The appearance color becomes light and obvious, and the transfer dyeing is serious | The appearance color is slightly lightened and slightly dyed |
| Commercial paper yarn and polyester yarn cross-twisting product | The appearance color is slightly lightened and slightly dyed | Slightly lighter appearance color and slightly pad dyeing |
As shown in table 2, the paper string prepared in example 2 has relatively good color fastness compared with the commercial paper string product. From the test results of example 1 and example 2, it can be seen that the color fastness of the paper rope obtained by twisting and weaving the paper yarn and the polyester filament is greatly improved. From the test results of example 1 and example 3, it can be seen that the paper yarn and the polyester filament yarn are better in cross twisting and weaving and have better color fastness performance than nylon filament yarn. Therefore, the existence of the nano-cellulose can enable the paper pulp to load more dyes, improve the color performance of the paper and enable the color fastness of the paper yarns to be increased. Meanwhile, in the process of twisting and weaving the paper rope product, the polyester filament yarns are added, and the color fastness performance of the paper rope product is greatly improved due to the excellent color fastness performance of the polyester. As can be seen from the comparison between the example 1 and the product of the cross-twisting of the polyester yarns on the market, the color fastness performance of the paper rope prepared in the example 1 is obviously superior to that of the product on the market.
Although the present invention has been disclosed by the above embodiments, the protection scope of the present invention is not limited thereto, and several deductions, substitutions and the like of the above components are made within the scope of the claims of the present invention without departing from the concept of the present invention.
