preparation example Construction

[0034] The invention discloses a method for preparing water-soluble vinylon fiber spunlace nonwoven fabric, which is made by adopting 100% water-soluble vinylon fiber through a combination of semi-crossing and parallel laying, and adopting a spunlace reinforcement technology. The fiber web after the first carding machine is then formed into a four-layer cross-laid fiber web by the action of the cross-lapper, which has the functions of anti-friction and anti-fluffing. The fibers passing through the second carding machine are laid in parallel to obtain a flat fiber web. The fiber webs from the two carding machines are overlapped and superimposed, and are reinforced by a hydroentanglement machine to form six layers of four functional layers on the top and two protective layers on the bottom. Composite structure. Then it is dried by a drying machine, and then the water-soluble vinylon nonwoven material of the required specification is made through winding, slitting and other proce...

Embodiment 1

[0052] A kind of manufacture method of above-mentioned vinylon spunlaced nonwoven fabric 4, with reference to attached figure 1 , including the following steps:

[0053] (1) Prepare the fiber web of cross-lapping: adopt 100% water-soluble vinylon fiber, the average length of vinylon fiber is 38mm, the average fineness is 1.67dtex, the grammage of the fiber web of gained is 25.3g / m 2 , the fiber raw materials are sequentially opened by the W1051A cotton opener, carded by the AUTEFA carding machine and laid by the AUTEFA 500889 cross-lapper to obtain a 4-layer fiber web.

Abstract

The invention discloses a preparation method of a water-soluble vinylon fiber spunlace nonwoven fabric, which comprises the following steps: using 100% water-soluble vinylon fiber to prepare a cross-laid fiber web protection layer; using 100% water-soluble vinylon fiber to prepare a parallel-laid fiber web Mesh functional layer; spunlace compounding; drying; slitting and packaging, slitting and winding on the slitting machine according to the required specifications. The invention has the characteristics of good moisture absorption and air permeability, high strength, good chemical stability and fast water-soluble degradation. The invention does not produce any harmful pollutants during the production process, and the product can be degraded quickly in boiling water. It is fully in line with the current trend of green and environmental protection.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabric preparation, in particular to a method for preparing water-soluble vinylon fiber spunlace nonwoven fabric. It can be widely used in but not limited to the field of medical hygiene, protective clothing and water-soluble packaging materials. Background technique [0002] With the continuous emergence of new technologies, the functions of nonwovens have been continuously improved, and their applications have become more and more extensive. As a new type of nonwoven production technology, spunlace nonwoven technology has short processing process, no pollution to the environment, no damage to fibers during processing, no adhesive, and the products are hygroscopic, soft and high strength. In the prior art, the main raw material of spunlace nonwoven products is polyester. Although polyester spunlace nonwovens have good performance characteristics, they are difficult to degrade in a natural state...
