At present, the production process of dyed cotton spunlace products is: cleaning - degreasing - bleaching - drying - carding - laying - spunlace - drying - dyeing - finished product coiling, in this production method, due to spunlace The cotton fibers are entangled together to initially form a spunlace product with texture. When dyeing it, the whole spunlace product needs to be dyed, which requires more dyes and costs more.

Embodiment 1
[0030] Such as figure 2 Shown is a dyed cotton spunlace product 1 provided by the present invention, which includes multiple layers of dyed cotton fibers 11, and each layer of dyed cotton fibers 11 is formed by intersecting single fibers 111 with mixed colors.
[0031] Such as figure 1 As shown, the present invention simultaneously provides a production process for producing the above-mentioned dyed cotton spunlace product 1, comprising the following process steps:
[0032] (1) Raw material preparation: Raw cotton, that is, pure natural seedless lint cotton, is prepared for use.
[0033] (2) Blowing: Utilize the cleaning machine to remove impurities and defects in the raw cotton. This step is a known technology and is the same as the prior art.
[0034] (3) Degreasing: wax and grease on the cotton fibers are removed to enhance the water absorption of the cotton fibers. This step is the same as the degreasing process in the prior art.
[0035] (4) Bleaching: to obtain bleac...
Embodiment 2
[0045] Such as image 3 Shown is another dyed cotton spunlace product 2 provided by the present invention, which includes multiple layers of dyed cotton fibers 21, each layer of dyed cotton fibers 21 is a different color, and the cotton fibers of different colors are alternately stacked at intervals. In this embodiment, the dyed cotton fibers 21 include white cotton fibers 211 and red cotton fibers 212, wherein the red cotton fibers 212 are placed between two layers of white cotton fibers 211, and the white cotton fibers 211 are composed of white single fibers 2111 The red cotton fibers 212 are formed by crossing each other, and the red cotton fibers 212 are formed by crossing red single fibers (not shown).
[0046] The present invention simultaneously provides a production process for producing the above-mentioned dyed cotton spunlace product 2, comprising the following process steps:
[0047] (1) Raw material preparation: Raw cotton, that is, pure natural seedless lint cott...

Abstract
The invention is applied in the field of non-woven fabrics, and provides a dyed cotton spun-laced production process and a dyed cotton spun-laced product. The process comprises the following steps of: blowing, degreasing, bleaching, dyeing, primary drying, carding, lapping, spinning-lacing, secondary drying and finished product coiling. The dyed cotton spun-laced product obtained by the process has multiplayer dyed cotton fibers, and the dyed cotton fiber of each layer contains multiple colors and can also contain one color. Spinning-lacing and dyeing in the traditional dyed cotton spun-laced production process are changed into dyeing and spinning-lacing, only partial cotton fibers before spinning-lacing are dyed, then un-dyed cotton fibers and the dyed fibers are blended in different modes, and finally the cotton fibers of different colors are fully entwisted by the spinning-lacing treatment and the colors are distributed uniformly, so that the dyed cotton spun-laced products of different styles can be obtained, and meanwhile, the purpose of obtaining good dyeing effect with little dye is also fulfilled; and compared with the traditional process, the production cost is saved.
Description
technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to a dyed cotton spunlace production process and product. Background technique [0002] Spunlace products generally use natural cotton as raw material, and use high-pressure water needles to spray cotton fiber webs to fully entangle the fibers in the fiber webs. It is widely used due to the advantages of sufficient raw materials, simple handling, softness, and good water absorption. At present, the production process of dyed cotton spunlace products is: cleaning - degreasing - bleaching - drying - carding - laying - spunlace - drying - dyeing - finished product coiling, in this production method, due to spunlace The cotton fibers are entangled together to initially form a spunlace product with lines. When dyeing it, it is necessary to dye the whole spunlace product, which requires more dyes and costs more. Contents of the invention [0003] The technical pro...
