Embodiment Construction

[0018] When using one roving process and feeding single roving into the spinning frame, there are many idiopathic yarn defects, regular and evenness; poor spinnability, many ends broken, poor evenness, yarn hairiness, single yarn strength Low, unstable production, which is not conducive to the normal production of subsequent processes. Through adopting the production technique of the present invention, namely adopt: two road roving technique and double roving feeding spinning frame technique; Adopt the polytrimethylene terephthalate (PTT) fiber of (20~80)% with blending ratio and (80 ~20)% viscose blended yarn count is 14 ~ 37tex (42 s ∽16 s ) products have excellent yarn quality, strong spinnability, increased single yarn strength, reduced hairiness, evenness, and its physical indicators have reached the Q / WFBF 05-2004 standard. The number of branches is 14~37tex (42 s ∽16 s ) blended yarn, the knitted fabric has a smooth, uniform surface, good elasticity, soft hand feeli...

Abstract

The invented polytrimethylene terephthalate (PTT) second rove and double-rove feeding production process and product relates to the field of yam spinning technique of textile technology. Said invention utilizes the addition of process making first rove and double-rove be fed into spinning frame, and defines new blending ratio so as to overcome the defects of existent similar techniques. The product produced by adopting said invented new process is specially suitable for making high-grade knitted garment.

Description

Technical field: [0001] The invention relates to the field of spinning technology of textile technology. Background technique: [0002] The existing polytrimethylene terephthalate (PTT) fiber has low breaking strength and poor cohesion, and adopts a roving and a single roving feeding process for spinning, which has the following technical defects: poor spinnability; evenness Poor; single yarn hairiness is high; single yarn strength is low, which is not conducive to the subsequent production process. It is necessary to improve the spinnability performance of polytrimethylene terephthalate (PTT) fiber products; improve evenness; improve single yarn breaking strength and reduce single yarn hairiness, so as to facilitate the production of subsequent processes. Invention content: [0003] The purpose of the present invention is to provide a kind of spinnability that can improve polytrimethylene terephthalate (PTT) fiber product, improve evenness, improve single yarn breaking s...
