Method for weaving polyvinyl alcohol fiber lining cloth capable of dissolving in water at normal temperature

Abstract

The invention discloses a method for weaving polyvinyl alcohol fiber lining cloth capable of dissolving in water at normal temperature, comprising the following steps: (1) preparing polyvinyl alcohol fiber cotton; (2) loosely stirring the polyvinyl alcohol fiber cotton and splitting the polyvinyl alcohol fiber cotton into loose fine carded polyvinyl alcohol fiber cotton, evenly scattering and distributing the loose fine carded polyvinyl alcohol fiber cotton on a meshy conveying belt, and conveying the loose fine carded polyvinyl alcohol fiber cotton into a cotton spreading machine; (3) uniformizing and leveling the cover of cloth by the clamping and the rolling of the cotton yarn of cloth layer by two groups of axial rollers and the stretching of the cotton yarn of cloth layer by spiral sawtooth points, wherein sawteeth are distributed on the surfaces of the two groups of axial rollers which are arranged up and down; (4) hot rolling, strengthening and shaping cotton cloth by hot rolling wheels, wherein convex points are distributed on the surfaces of the hot rolling wheels; (5) making the rolled cotton cloth pass by the surface of a cooling cylinder wheel in which circulating ice water is filled so that the cotton cloth being rapidly cooled to the normal temperature; and (6) bundling the cotton cloth into a bundle. When being used for base cloth embroidered by a machine, the polyvinyl alcohol fiber lining cloth woven by the method can dissolve in water at lower normal temperature, and the embroidered threads can not fade when the polyvinyl alcohol fiber lining cloth dissolves in water at high temperature.

Description

technical field [0001] The invention relates to a method for weaving normal-temperature water-soluble interlining cloth with polyvinyl alcohol fibers as raw materials. Background technique [0002] Lace factories usually need to add base cloth to the embroidery thread when using machines to embroider. In order to keep the embroidered part beautiful and natural after embroidery is completed, some products must use interlining as the base material for the base fabric. Cloth base material, because the base fabric base material should be removed after embroidery, leaving only the embroidery thread part, and at the same time, the finished product can produce the style of hand embroidery. The choice of base fabric base material is relatively diverse, one of the more common choices is the interlining woven from polyvinyl alcohol fibers, which is generally called water-soluble interlining on the market. Reducing the processing time can also reduce the processing cost. Just put the ...

[0004] However, when the embroidery thread selected by the lace factory has poor color fastness (such as gold, silver and bright color series of embroidery threads), when the existing water-soluble lining is dissolved in high-temperature hot water, it will not only make the embroidery thread If the color fades, the withdrawn pigment molecules will also be transferred to other parts of the embroidery product, causing damage to the quality of the embroidery product
