Some companies also add a certain amount of ES two-component adhesive fibers to their products to improve the strength of the product through thermal bonding and reinforcement. However, since ES fibers themselves are non-degradable fibers, they are easily thrown into the sewer after use. Accumulated, it is easy to form clogged municipal sewer pipes after a long time

Embodiment Construction
[0025] The present invention is described below in conjunction with accompanying drawing and specific embodiment:
[0026] A process for producing a flushable and degradable spunlace nonwoven fabric by a stepwise mixing method, comprising the following steps:
[0027] 1. Pulp preparation: fully mix pulp short fiber and degradable long fiber with water to make a mixed fiber slurry of pulp short fiber and degradable long fiber with a concentration of 0.02%-0.05%; the pulp ratio range According to the customer's requirements for the product, it can fluctuate in the range of 50%-80%. The mass ratio of degradable long fibers to the mixed fibers is 20%-80%, and the length of degradable long fibers is 8-16mm.
[0028] 2. Set the stepped output end and the slurry step-type mixing The step-type mixing of the slurry: the output end of the slurry distributor 1 (preferably a conical slurry distributor) is connected with a stepped output end, such as figure 1 As shown, the stepped output ...

Abstract
A laddering mixed process for producing washable and degradable spunlace non-woven fabric comprises the steps of S1. pulp preparation; S2. theladdering output end isset and the pulp laddering is mixed; S3. wet-laying; S4. spunlace; S5. drying and winding. The laddering mixed process for producing washable and degradable spunlace non-woven fabric has simple process method, which ensures product flushability and usage frequency, through mixed fiber pulp formed by pulp short fiber and degradable long fiber passing thick round pipe, thin round pipe and thin square pipe laddering at output end successively to flow into formed end as enormous microturbulence and ensured the complete mixing of pulp short fiber and degradable long fiber as well as stability and also ensures the forming of even fiber web. While spunlace under spunlace pressure of 30-100bar ensures effective fiber entanglement without damaging fiber intrinsic performance, enabling the fine usage performance of fiber.
Description
technical field [0001] The invention relates to a production process of spunlace non-woven fabrics, in particular to a process for producing flushable and degradable spunlace non-woven fabrics by a stepwise mixing method. Background technique [0002] Flushable spunlace nonwovens are a kind of spunlace nonwovens. Compared with general spunlace nonwovens, they are flushable and degradable, and can completely replace non-degradable and petroleum-consuming polyester wipes. And the cost is very competitive. [0003] In June 2008 at the World Wipes Congress, the North American Nonwovens Industry Association (INDA) and the European Nonwovens Association (EDANA) jointly developed guidelines for flushability of absorbent hygiene products. "Flushable" nonwoven fabric means that the material has a certain strength during use. When the material is deposited in a large amount of water or aqueous solution, the fiber web can be broken into individual cellulose fibers under mild agitation...
