Embodiment 1

[0043] Embodiment 1 provides a composite method of air-through non-woven fabric and cotton non-woven fabric, the method comprising: the air-through non-woven fabric is used as the bottom layer, the non-woven fabric cotton web is laminated on the air-through non-woven fabric, and after pre-wetting , The finished product is obtained after the front and back spunlace compounding. Among them, the superposition of two layers of cloth needs to place the hot air non-woven fabric under the cotton non-woven fabric, because the hot air non-woven fabric has been initially formed, the surface tension of the chemical fiber is relatively large, the cloth surface is smooth, and the high-pressure water thorn flow directly hits the hot air. The non-woven fabric is not easy to penetrate, and the cotton net is not easy to pre-wet to discharge the air between the cotton layers; on the contrary, if the hot-air non-woven fabric is placed below, the high-pressure water thorn flow passes through the c...

Embodiment 2

[0070] see figure 2 with 3 , embodiment two provides a kind of preparation method of jacquard composite non-woven fabric, comprises the following steps:

[0071] S101 Opening and mixing: Opening, removing impurities and mixing raw cotton to obtain raw cotton fibers.

[0072] S102 carding into a web: carding the fibers provided in step S101 into a fiber web.

[0073] S103 cross-lapping: spread the fiber web obtained in step S102 in a reciprocating and staggered manner.

[0074] S104 Multi-roller drafting: Use different drafting speeds to adjust the arrangement of fibers to obtain non-woven cotton webs.

[0075] The above-mentioned process is the same as the production method of the existing spunlace cotton non-woven fabric. If a normal spunlace process is installed afterwards, its grammage will be 25-180 grams per square meter.

[0076] S105 Lamination: The non-woven fabric cotton web obtained in step S104 reaches the support net after multi-roller drafting, and the hot-ai...

Embodiment 3

[0084] Embodiment three provides a kind of preparation method of plain weave composite nonwoven fabric, and its method is basically consistent with step S101-S110 of embodiment two, and in step S110, jacquard roller is used as common hydroentanglement roller, plays the role of strengthening hydroentanglement nonwoven The effect of the vertical and horizontal strength of the cloth is different: it also includes: S111 Finishing: use flat net spunlace to finish the cloth surface twice (if there are missing stitches in the previous spunlace process, these two spunlace heads can to modify the fluff of the cloth surface), the spunlace pressure is the same as the finishing spunlace pressure in the production process of the existing spunlace cotton non-woven fabric.

Abstract

The invention discloses a compounding method of hot air through nonwoven fabric and all cotton nonwoven fabric, and belongs to the technical field of nonwoven fabric production. The method comprises the following steps: taking hot air through nonwoven fabric as the bottom layer, laminating a nonwoven fabric-cotton mesh on the hot air through fabric, and carrying out pre-wetting and front-back spunlace laminating to obtain the product. According to the method, a spunlace method is used to replace chemical adhering to compound chemical fiber nonwoven fabric and all cotton spunlace nonwoven fabric; the advantages of all cotton nonwoven fabric such as softness, water absorbing property, breathability, and the like, are preserved, at the same time, the advantages of hot air through nonwoven fabric such as high filling power, good elasticity, soft hand feeling, strong warm keeping performance, air penetrating and water penetrating performance, and the like are also preserved; moreover, the glue leakage is prevented, and the peeling strength meets the requirement.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric production, and in particular relates to a composite method of hot-air non-woven fabric and cotton non-woven fabric and a production system thereof, especially relates to a hot-air non-woven fabric (chemical fiber) and cotton spunlace non-woven fabric. The cloth adopts the process of physical spunlace compounding. Background technique [0002] Hot air non-woven fabric: one of the hot air bonded (hot rolling, hot air) non-woven fabrics. After the fiber (chemical fiber) is carded, the hot air on the drying equipment penetrates the fiber web to heat it. And the non-woven fabric that can be bonded. [0003] Cotton spunlace non-woven fabric: Cotton spunlace non-woven fabric is made of natural fiber pure cotton. After opening and loosening the cotton, the pure cotton is sorted into a net by using a cutting-edge carding machine, a web laying machine and a drafting machine. The dense needle-sha...
