Abstract

The invention provides a preparation method of a suede fabric for an automobile roof. The preparation method comprises the following steps: weaving grey cloth in a circular weaving mode by adopting monofilament conventional yarns, and performing pre-shaping, dyeing, suede drying, fluffing and suede shaping on the grey cloth. The light-weight suede fabric which can be applied to the automobile roofcan be prepared. The suede fabric comprises a fabric layer and a supporting layer, and the weight of the suede fabric is 190g / m <2> to 225g / m <2>. The suede fabric is directly made of conventional polyester yarn, strong base and strong acid solution treatment is not needed in the dyeing process, the difficulty of the production process is reduced, and pollution to the environment is reduced. Themonofilament polyester yarns are slightly thicker than the alkali-treated yarns, so that the processing steps are simplified. The supporting layer yarns are used as a main body of finished fabric to support the whole fabric, so that the strength is ensured. The light-weight suede fabric also has the advantages of better flame retardance, higher tensile strength and shrinkage elasticity, and strongwear resistance and light color fastness.

Description

technical field [0001] The invention relates to the technical field of making automotive interior ceiling materials, in particular to a method for preparing suede-like fabrics for automotive ceilings. Background technique [0002] Imitation suede fabric is a kind of artificial fabric similar to suede. In the textile industry, imitation suede fabric is called imitation suede or imitation suede, but in the textile industry, It is generally used to call imitation suede or imitation suede directly suede. Suede can be divided into knitted and woven. Knitted suede is divided into warp-knitted suede (more common) and weft-knitted suede. Woven suede is divided into warp-knitted suede and weft-wise suede. velvet. [0003] The feel and appearance of imitation suede are quite similar to natural suede, and its surface texture is also similar to natural suede. After special finishing, it is fine and smooth, soft and plump, more durable than natural suede, and easier to maintain ;It is...
