Description
Technical Field
The application belongs to the technical field of textile size, and particularly relates to textile size with high adhesion performance and a preparation method thereof.
Background
In the process of manufacturing the yarn into the fabric, the weaving machine can repeatedly perform mechanical actions such as stretching, bending and friction on the yarn, so that the yarn needs to be strong enough to bear the strength in the weaving process, and the problem that fluffing and even breaking occur in the manufacturing process to influence the quality of the grey fabric is avoided. The textile size is usually adopted to size the yarns to improve the strength and the toughness of the yarns, improve the wear resistance of the yarns, ensure the hairiness of the yarns to be more comfortable and improve the weavability of the yarns.
Textile size used in the domestic textile industry is currently mainly divided into three types, namely starch size, polyvinyl alcohol size and acrylic size. The starch size uses starch as the main component of the size, but the starch size has insufficient adhesion to yarn fibers due to a cyclic polyhydroxy structure in the starch, and the starch size has high hardness and brittleness, so that the starch needs to be modified to better meet the requirement of yarn sizing. The polyvinyl alcohol sizing agent can form a film layer with better performance on the surface of the yarn to improve the weaving performance of the yarn, but the main component polyvinyl alcohol of the polyvinyl alcohol sizing agent is difficult to explain in natural environment and is easy to cause environmental pollution. The acrylic sizing agent has good adhesion to the yarn, is easy to form a film, has good flexibility after film forming, is beneficial to yarn weaving, and is easy to biologically explain, more environment-friendly and higher in cost compared with polyvinyl alcohol.
In view of the above, there is a need to develop a textile size that is more environmentally friendly, has high adhesion to yarns, has good flexibility of film layers, and is low in cost.

In table 1, viscosity thermal stability: stirring and heating the textile slurry to 95 ℃, firstly measuring the viscosity of the slurry when the temperature is kept for 1h, then measuring the viscosity of the slurry every 30min until 3h, measuring the viscosity of the slurry for five times in total, and calculating the thermal stability of the viscosity:
viscosity thermal stability (%) = 100-viscosity fluctuation ratio
Viscosity fluctuation ratio (%) = (max | η - η' |/η) × 100.
Wherein eta is the viscosity value of the slurry measured at the temperature of 95 ℃ for 1 h; max eta-eta' |/eta is the extreme difference of viscosity values measured five times at 95 ℃ for 1h and then every 30 min.
In table 1, breaking strength of slash: the slashing was first placed in a constant temperature and humidity cabinet 65% RH at 20 ℃ for 48h, and then the break strength of the slashing was tested on a single yarn strength meter.
As can be seen from Table 1, examples 1 to 8 of the present application were preparedThe viscosity thermal stability of the textile size is more than 95.6 percent, the adhesive force to cotton fiber is more than 50.2N, and the breaking strength of slashes prepared by the textile size of the embodiment 1-8 is 63.7N/mm 2 As described above, the textile size prepared in examples 1 to 8 of the present application has good thermal stability, good adhesion to cotton fiber, and high breaking strength of the prepared slashing.
As can be seen from comparative example 1, when sodium carbonate of example 3 was replaced with an equal weight part of sodium polyphosphate in comparative example 1, the adhesion of the prepared textile size to cotton fiber was significantly reduced, and the breaking strength of sized yarn was also reduced, which is probably because the swelling effect of sodium polyphosphate added alone to yarn was not as good as that of sodium carbonate and sodium polyphosphate added together, resulting in the failure of the size to better penetrate into yarn, affecting the absorption of the size by yarn, and thus affecting the adhesion and breaking strength.
As can be seen from comparative example 2, when sodium polyphosphate in example 3 was replaced with an equal weight part of sodium carbonate in comparative example 2, the adhesion of the prepared textile size to cotton fibers was significantly reduced and the breaking strength of slashed yarns was reduced, probably because the swelling effect of sodium carbonate alone to yarns was not as good as that of sodium carbonate and sodium polyphosphate simultaneously added, resulting in the failure of the size to penetrate into yarns well, affecting the absorption of the size by yarns, and thus affecting the adhesion and breaking strength.
It can be seen from comparative example 3 that, in comparative example 3, sodium carbonate and sodium polyphosphate are not added, but the sodium carbonate and the sodium polyphosphate are distributed into other substances in parts by weight, so that the adhesion of the prepared textile size to cotton fibers is remarkably reduced, the breaking strength of slashes is also remarkably reduced, and probably because the sodium carbonate and the sodium polyphosphate are not added, the textile size cannot be effectively swelled, the absorption of the size by yarns is reduced, the adhesion capability is reduced, and the size cannot be effectively infiltrated into the yarns, so that the breaking strength of the slashes is reduced.
It can be seen from comparative example 4 that when less sodium carbonate and more sodium polyphosphate were used in comparative example 4, the prepared textile size decreased in both the adhesion to cotton fibers and the breaking strength of slashing, indicating that relatively more sodium carbonate was advantageous in increasing the swelling effect of fibers and increasing the absorption of size, thereby improving the adhesion and breaking strength of slashing.
The present embodiment is merely illustrative, and not restrictive, and various changes and modifications may be made by persons skilled in the art without departing from the scope and spirit of the present invention. The technical scope of the present application is not limited to the content of the specification, and must be determined according to the scope of the claims.
