Embodiment 1

[0020] A novel stitch-bonded Lixin cloth of the present invention is made of 30wt% of bamboo fibers with a fiber fineness of 1-7D and a fiber length of 25-70mm and 70wt% of chemical fibers through a non-woven method. Wherein, the chemical fiber used is polyester fiber, polypropylene fiber or acrylic fiber.

[0021] The manufacture method of a kind of novel seam-bonding Lixin cloth of the present invention, is that 1-7D is 1-7D with 30wt% fiber fineness, and the fiber length is the mixture of the bamboo fiber of 25-70mm and the chemical fiber of 70wt% as raw material, thus raw material It is manufactured through the processes of opening, carding, net laying, stitching and tentering in sequence. Wherein, the chemical fiber used is polyester fiber, polypropylene fiber or acrylic fiber. in:

[0022] The opening process is: send the raw bamboo fiber and chemical fiber into the opening machine to make it fluffy to the greatest extent and mix them together evenly;

[0023] The car...

Abstract

The invention discloses a novel stitch knitting stitch bond fabric and a preparation method thereof. The stitch bond fabric is prepared by raw material of mixed material of 30-100wt% of raw bamboo fiber with the fiber fineness of 1-7D and the fiber length of 25-70mm and 0-70wt% of chemical fiber through opening, carding, lapping, stitch knitting and tentering sizing procedures in sequence. The invention takes natural degradable raw bamboo fiber as main raw material and has the advantages of environment protection and degradable ability, good antibacterial action and strong hydroscopic property and the like, wherein the bacteriostasis rate reaches 60-90%, and the moisture regain of 120min at 140 DEG C is more than or equal to 8; besides, fiber web is only processed by stitch hemming for reinforcement, the undisturbedness of the fiber web is maintained, poriness is high, and ventilation property is excellent, the ventilation property of 120min at 140 DEG C is more than or equal to 200L / dmmin. Meanwhile, the product has small thermal contractibility through the tendering sizing procedure, and the thermal contractibility of 120min at 140 DEG C is less than or equal to 1%.

Description

technical field [0001] The invention relates to the application field of stitch-bonding of nonwoven fabrics, in particular to a stitch-bonded Lixin cloth and a manufacturing method thereof. Background technique [0002] At present, Lixin cloth produced by stitching technology in the field of non-woven fabrics is mainly made of non-degradable chemical fibers. For example, polyester fiber, polypropylene fiber, acrylic fiber, etc. are used as raw materials. These fibers are thermoplastic fibers. The Lixin cloth produced is relatively poor in air permeability and moisture absorption performance, and has no natural antibacterial effect. [0003] Bamboo fiber has the advantages of excellent antibacterial, good air permeability, and strong hygroscopicity, which have been widely recognized by everyone. At present, bamboo pulp fibers made of bamboo as raw materials have been applied to various fields of textiles, but due to previous production costs and technical conditions Factors ...
