Embodiment Construction
[0023] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0024] like figure 1 As shown, the puffing device of this embodiment is used to produce regenerated fiber puffed filaments using bottle flakes as raw materials. The above-mentioned puffing device includes a casing 10 and a thread path 20 arranged in the casing 10 . The thread path 20 includes a thread feed section 21 , a thread travel section 22 , an expansion section 23 and a thread outlet section 24 which are connected in sequence from top to bottom. One end of the wire feeding section 21 away from the wire running section 22 forms a wire passage inlet 211 , and one end of the wire outlet section 24 away from the expansion section 23 forms a wire passage outlet 241 ...

The invention provides a puffing device and a puffing method. The puffing device comprises a casing and a wire channel disposed in the casing; the wire channel comprises a wire inlet segment, a wire running segment, an expansion segment and a wire outlet segment which are sequentially connected; a wire channel inlet is formed at an end of the wire inlet segment and away from the wire segment; a wire channel outlet is formed at an end of the wire outlet segment and away from the expansion segment; a first inlet channel and a second inlet channel communicating with the wire channel are respectively arranged on both sides of the junction between the wire running segment and the expansion segment; and the wire running segment is characterized by a diameter of 1.3 mm to 1.5 mm, and a length of20 mm to 22 mm. The technical solution of the present invention can effectively solve the problem that the puffing device of the prior art has a low degree of product expansion when a bottle piece isused as a raw material.
Description
technical field [0001] The present invention relates to the technical field of chemical fiber manufacturing, in particular, to a puffing device and a puffing method. Background technique [0002] At present, the technology of using petroleum chips to produce puffed silk is stable at home and abroad. No matter whether the existing domestic or imported original puffers are used, they can be produced normally, and the product indicators are stable. However, the raw material used in the production of regenerated fiber bulked yarn is PET bottle flakes. Since the melting point and softening point of the bottle flakes are 40°C lower than those of the slices, if the puffing temperature of the slices is still 200°C, the filaments have softened or melted when entering the extruder, which is easy to block the extruder, produce stiff silk, yarn Significant drop in thread strength, yarn breakage in post-twisting and weaving, impact on the production efficiency of subsequent processes, u...
