Technical Field

The invention relates to the technical field of spinning, in particular to a bamboo fiber and chemical fiber interwoven fabric and a weaving method thereof.

Background

The special superfine micropore structure in the bamboo fiber enables the bamboo fiber to have strong adsorption capacity, so that the bamboo fiber has good hygroscopicity and air permeability, and is known as a respiratory fiber by experts. And the bamboo fiber contains 'bamboo jade' antibacterial substances, so that the clothes made of the bamboo fiber also have the effects of deodorizing and removing peculiar smell. The ultraviolet penetration rate of the bamboo fiber is six ten-thousandth, the ultraviolet resistance is 41.7 times of that of cotton, the bamboo fiber does not have any free charge, is antistatic, stops itching and is comfortable to wear. The bamboo fiber is also a real environment-friendly green product, has no chemical components and no pollution, and is 100 percent biodegradable. But bamboo fiber also has a hard-brittle nature. The wear resistance is not good as a cotton fabric based on the characteristics of the production process of a bamboo fiber product, the higher the content is, the more comfortable the use is, the less wear resistant the product is, the yarn is easy to fall and break compared with a cotton product, and the service life is not long as the cotton fabric. Furthermore, the bamboo washing fiber fabric can not be twisted and kneaded forcefully, otherwise the bamboo washing fiber fabric is easy to damage. It is a new development trend to adopt new technology to promote the performance of bamboo fiber fabric.

Preferably, the primary impregnation mangle ratio is 85% -90%, and the secondary impregnation mangle ratio is 90% -95%.

The invention is based on the fact that bamboo fibers are weaker in elasticity than synthetic fibers, and therefore the maximum tension value of the bamboo fibers is taken as the maximum pressure value applied by a weaving machine for weaving. According to the technical scheme, the defects that single bamboo fiber is fragile and easy to damage are overcome by adopting a mode of blending the bamboo fiber, the modal fiber and the viscose fiber in proportion in the weft yarn. Meanwhile, the method of two-dipping and two-rolling treatment is adopted in the weaving method, so that the wrinkle resistance and the shrinkage rate of the fabric are improved. The primary impregnation is by crosslinking the fibers with a finish. When the system is acted by external force, due to covalent crosslinking or resin fixation, the deformation of cellulose macromolecules can be reduced, the relative displacement between fiber molecules is more effectively limited, and the displacement resistance is improved, so that the aim of resisting wrinkles is fulfilled. After the secondary impregnation, impurities are taken away by washing, and then the sizing is carried out, so that the influence of the impurities on the shrinkage can be avoided. In addition, the baking time is short, the setting temperature is not more than 140 ℃, the strength of the fabric can be well maintained, and the wrinkle resistance of the fabric is improved while the fabric is prevented from being greatly influenced by high temperature. The fabric adopts warp surface satin, warp yarns are shown on the surface, weft yarns are shown on the back surface, the outer surface is firm and durable, the inner surface is skin-adhered and comfortable, simultaneously, the wrinkle resistance, the wear resistance and the shrinkage of the bamboo fiber fabric are improved, and the economic value of the fabric is improved.
