Latex solution for producing lignin nonwoven cloth for cigarette

Abstract

The invention discloses latex used for the production of tobacco used wood pulp non-woven, which consists of an adhesive, a cross-linking agent, water and a curing agent and a stabilizer; the adhesive is any one of the following substances: vinyl acetate, vinyl acetate copolymer, acrylic ester and acrylic copolymer or the mixture of vinyl acetate and vinyl acetate copolymer or the mixture of acrylic ester and acrylic copolymer; the cross-linking agent is any of the following substances: HMMM, polyfunctional aziridine, bifunctional end aziridine or closed isocyanate; the curing agent is ammonium chloride; and the stabilizer is ammonia water. Compared with the prior art, the tobacco used wood pulp non-woven produced with the latex has the advantages of higher humidity and strength, lower moisture regain, good compression elasticity, as well as good stiffness and filtering performance when being used as cigarette holder so that the cigarette is not apt to occur hot collapse or generate foreign odor when being smoked.

Description

technical field [0001] The invention relates to a latex for producing wood pulp non-woven fabrics, and in particular to a latex for producing wood pulp non-woven fabrics for cigarette filters. Background technique [0002] Traditional non-woven fabrics are mainly produced by methods such as spinning, melt blown, spunlace, needle punching, thermal bonding and chemical bonding. The web-forming technology mainly adopts dry-laid (including mechanical-laid and air-laid), wet-laid and polymer extrusion-laid. The reinforcement process of the fiber web includes mechanical reinforcement, chemical bonding and thermal bonding. [0003] Typically, air-laid, dry-laid, card-laid, and wet-laid nonwovens are different from traditional textiles that rely on yarn interweaving to create cohesion, and have little strength without treatment. In practice, they require physical, chemical or thermal consolidation to provide sufficient strength, stiffness and resilience, etc. [0004] When non-wo...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the shortcomings of low wet strength, high moisture regain, and poor compression resilience in the prior art, the present invention provides a latex for producing wood pulp non-woven fabrics for cigarettes, which has high wet strength, high moisture regain Advantages of low pressure and good compression resilience
