Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] like figure 1 As shown, the puffing device of this embodiment is used to produce regenerated fiber puffed yarn using bottle flakes as raw material. The above-mentioned puffing device includes a casing 10 and a silk channel 20 arranged in the casing 10 . The wire path 20 includes a wire feeding section 21 , a wire feeding section 22 , an expanding section 23 and a wire outlet section 24 which are sequentially connected from top to bottom. The end of the wire feeding section 21 away from the wire running section 22 forms a wire channel inlet 211 , and the end of the wire outlet section 24 away from the expansion section 23 forms a wire channel outlet 241 . Both sides of the connection b...

Abstract

The present invention provides a puffing device and a puffing method, wherein the puffing device includes a casing and a silk channel arranged in the casing, and the silk path includes a silk feeding section, a silk feeding section, an expanding section and a silk outlet section connected in sequence, The end of the wire feeding section away from the wire feeding section forms the wire channel inlet, and the end of the wire outlet section away from the expansion section forms the wire channel outlet, and the two sides of the connection between the wire feeding section and the expanding section have the first air inlet channel connected with the wire channel And the second air inlet is characterized in that the diameter of the wire-running section is 1.3mm to 1.5mm, and the length of the wire-running section is 20mm to 22mm. The technical scheme of the invention can effectively solve the problem of low product expansion degree when the expander in the prior art uses bottle flakes as raw material.

Description

technical field [0001] The invention relates to the technical field of chemical fiber manufacturing, in particular to an expanding device and an expanding method. Background technique [0002] At present, the technology of producing puffed silk by using petroleum slices at home and abroad is stable, no matter using the existing domestic or imported original puffers, it can be produced normally, and the product indicators are stable. However, the raw material used in the production of regenerated bulked yarn is polyester bottle flakes. Since the melting point and softening point of bottle flakes are 40°C lower than that of slices, if the puffing temperature of slices is still 200°C, the filaments have already softened or melted when they enter the puffer, which will easily block the puffer, resulting in stiff silk, yarn The thread strength is greatly reduced, the post-twisting and weaving yarn breakage, the production efficiency of the subsequent process is affected, and the...
