Abstract
The invention relates to imitating lining leather. A preparation process of the imitating lining leather comprises the following steps that step 1, polyester fibers are subjected to needling by a plurality of high-speed needling machines to obtain non-woven fabrics; step 2, imitation cotton velvet is laid on the non-woven fabrics, and mixing and strengthening are performed by the multiple high-speed needling machines; and step 3, cutting, pressing and rolling are carried out to obtain finished products; the weight ratio of the non-woven fabrics to the imitation cotton velvet is 7 to 8, and non-woven fabric and imitation cotton velvet raw materials are pre-dyed through color masterbatch. The imitating lining leather has the following advantages that multiple times of needling is performed on the non-woven fabrics to increase the density, so that the flexibility of the imitating lining leather is closer to lining leather; the imitation cotton velvet is smoother and softer than the non-woven fabrics in hand feeling, and the non-woven fabrics and the imitation cotton velvet are mixed for needling with the weight ratio of 7 to 8, so that the hand feeling of the imitating lining leatheris smoother; and meanwhile, the imitation cotton velvet is looser than the non-woven fabrics after multiple times of needling, and the non-woven fabrics are filled with the imitation cotton velvet, sothat the imitating lining leather is further enabled to be closer to the lining leather in terms of flexibility.
Description
technical field [0001] The invention relates to the field of non-woven fabrics, in particular to an imitation leather. Background technique [0002] The non-woven fabric is composed of directional or random fibers. The non-woven fabric has no warp and weft threads. It is very convenient to cut and sew, and it is light in weight and easy to shape. It is very popular among handicraft lovers. However, when using non-woven fabrics to make luggage linings, people hope that the non-woven fabrics can have a leather-like texture. [0003] The Chinese patent with publication number CN102587037A discloses an imitation leather nonwoven fabric and a preparation method thereof. The preparation method includes the following steps: (1) processing into a cotton web: raw polyester fibers are sequentially opened by needles and carded. A preliminary cotton web is formed after the machine carding and cotton laying machine lays cotton; (2) Needling reinforcement: the cotton web includes a fiber...
