Embodiment Construction

[0033] The invention provides a secondary polymerization process of fiber elastic body. The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings, so as to make it easier to understand and grasp.

[0034] Fiber elastomer secondary polymerization process, such as figure 1 shown, including the following steps:

[0035] Choose a fiber elastomer,

[0036] A fibrous elastic body made of heat-melt fibers and elastic polyester fibers laminated in a net is used.

[0037] Among them, the melting point of the hot-melt fiber is less than or equal to 110°C, and the fiber elastic body adopts the process in CN104805600B, and the hot-melt fiber and the elastic polyester fiber are mixed with long and short fibers and then hot-melt formed.

[0038] The fiber elastic body obtained by this process is relatively fluffy and has a certain degree of elasticity, but it meets the high elastic recovery requirements of cushions and...

Abstract

The invention discloses a fiber elastomer secondary polymerization process, which comprises the following steps: adopting a fiber elastomer layered by hot-melt fibers and elastic polyester fibers in a net; and performing penetrating deep cleaning on the fiber elastomer by spraying or soaking ; The fiber elastomer after deep cleaning is modified by spraying the modified solution, and the modified solution includes at least softener and chain extender; the sprayed fiber elastomer is heated by a hot air blower to obtain secondary polymerization Fiber Elastomer. The invention can improve the elasticity and softness of the fiber elastic body through the secondary polymerization process, meet the elastic recovery and softness requirements of cushions, mattresses and other cushion bodies, and has excellent fatigue resistance. By modifying the fiber elastomer before welding, it can take into account both heat setting and heat resistance, and the welding surface can be effectively protected, while the rigidity of the welding can be prevented, and the elasticity of the matrix will not be lost. The technological process is concise and ingenious, and is easy to implement and popularize.

Description

technical field [0001] The invention relates to a secondary polymerization process of fiber elastic body, and belongs to the technical field of fiber elastic body elasticity improvement technology. Background technique [0002] Fiber refers to a substance consisting of continuous or discontinuous filaments. In animals and plants, fibers play an important role in maintaining tissues. Fibers are widely used and can be woven into thin threads, thread ends and hemp ropes, and can also be woven into fiber layers when making paper or felt. They are also commonly used to make other materials and form composite materials with other materials. [0003] The Chinese invention patent with the authorized notification number CN104805600B discloses a bionic honeycomb cotton and its manufacturing method, which forms a bionic honeycomb cotton sub-layer by sorting the fiber bodies, and fuses the fiber bodies with different melting points through a hot-melt process to form Layered bionic hon...
