CN102808259A - Elastic yarn with comfortable elater - Google Patents

Abstract

The invention belongs to the field of textiles, and provides elastic yarn with comfortable elater. The elastic yarn is mainly characterized in that for the first time, traditional fiber is adopted to be mixed with the comfortable elater to spin the elastic yarn, wherein the comfortable elater is biomass elastic short fiber. Due to successful application of the comfortable elater, the historical situation that the elastic short fiber cannot be used for spinning is broken, and spandex elater can be replaced, so that the dependence of the elater over petrochemical resources and energy consumption are reduced. Compared with the prior spandex core-spun elastic yarn, the elastic yarn with the comfortable elater has the advantages of little hairiness detail, high elasticity, yarn evenness, no yarn deviation phenomenon, and the like, thereby laying a very good material basis for high-grade elastic fabric.

Description

A kind of easypro elater stretch yarn

Technical field

The invention belongs to field of textiles, relate to stretch yarn, propose a kind of novel elastic yarn, specifically propose a kind of easypro elater stretch yarn.

Background technology

Existing stretch yarn; It is a fixing covering device on ring throstle; Polyurethane elastic filament is sent into the preceding jaw of ring throstle by certain draw ratio, twist, polyurethane elastic filament is wrapped in the traditional fibre rove with the traditional fibre rove; Be spun into spandex core-covered stretch yarn, its process route is: the cotton fiber → lap → carded sliver → head also → two also → rove, polyurethane elastic filament → RING SPINNING.Polyurethane elastic filament is the elastic force long filament; Owing to receive the influence of factors such as the inclined to one side silk of polyurethane elastic filament quality and ring throstle; Spandex core-covered stretch yarn coats bad, adds that loom characteristic is limited, is prone to make the wrinkling float of fabrics cloth cover; Influence product quality, spandex core-covered stretch yarn can not adapt to the needs of producing high-grade elastic force cloth.

Summary of the invention

The applicant is a large-scale cotton spinning enterprise, in long-term weaving business activities, finds the today in the high-speed weaving machine development; Yarn filoplume is prone to make the loom opening unclear; Restricting woven production efficiency, and existing spandex core-covered stretch yarn is restricting the production of high-grade elastic force cloth because of certain defective is arranged, people have big demand to the elastic filament that is applicable to high-grade elastic force cloth; The personnel of organizational technology constantly tackle key problems; Purpose is to develop a kind of novel elastic yarn, and this stretch yarn can overcome the defective of existing stretch yarn, satisfies weaving production and consumption demand better.

The technical scheme that the present invention taked is a kind of easypro elater stretch yarn of design, adopts traditional fibre to mix at scutching cotton or mixing in doubling step with the easypro elater process of arbitrary proportion, is spun into a kind of easypro elater stretch yarn through ring throstle or rotor spinning machine.

Traditional fibre refers to cotton, fiber crops, wool and other chemical fibre, and easypro elater is a kind of living beings novel elastic staple fibre.

The present invention adopts the elastic force staple fibre to be used to spin stretch yarn first, has broken the historical situation that the elastic force staple fibre can not be used for the production spun yarn, is the once great innovation of textile industry; This easypro elater stretch yarn of the present invention is compared with existing spandex core-covered stretch yarn, and it is few to have a filoplume, and details is few; Elastic force is excellent, remarkable advantages such as the inclined to one side silk of the dried evenly nothing of bar phenomenon, the appearance of the easypro elater stretch yarn of the present invention; Be able to replace polyurethane elastic filament, make elastic filament reduce dependency degree, reduced energy resource consumption the petrochemical industry resource with the easypro elater of living beings; Reduced the greenhouse gas emission amount, economic results in society very significantly.

The specific embodiment

The present invention adopts cotton fiber and easypro elater in the 60:40 ratio, or other several kinds of process route blending below ratio process become a kind of easypro elater stretch yarn:

1. relax elater, the cotton fiber-lap-carded sliver-head also-two also-revolving cup spins-relaxes the elater stretch yarn;

2. { elater-lap that the relaxes-carded sliver, the cotton fiber-lap-carded sliver }-head also-two also-revolving cup spins-relaxes the elater stretch yarn;

3. relax elater, the cotton fiber-lap-carded sliver-head also-two also-rove-RING SPINNING-easypro elater stretch yarn;

4. { elater-lap that the relaxes-carded sliver, the cotton fiber-lap-carded sliver }-head also-two also-rove-RING SPINNING-the elater stretch yarn relaxes.

Spin through the examination of machine on ring throstle, the bar solid carbon dioxide of yarn is flat to be improved more than 30% with supporting ring ingot core-spun elastic yarn, and Yarn filoplume, cotton knot reduce respectively more than 50% with supporting ring ingot core-spun elastic yarn, and high-grade elastic force cloth provides good upstream product in order to weave.

Claims (2)

1. an easypro elater stretch yarn is characterized in that adopting traditional fibre to mix at scutching cotton or mixing in doubling step with the easypro elater process of arbitrary proportion, is spun into a kind of stretch yarn through ring throstle or rotor spinning machine.

2. easypro elater stretch yarn as claimed in claim 1 is characterized in that said stretch yarn adopts following process route spinning:

1. relax elater, the cotton fiber-lap-carded sliver-head also-two also-revolving cup spins-relaxes the elater stretch yarn;

2. { elater-lap that the relaxes-carded sliver, the cotton fiber-lap-carded sliver }-head also-two also-revolving cup spins-relaxes the elater stretch yarn;

3. relax elater, the cotton fiber-lap-carded sliver-head also-two also-rove-RING SPINNING-easypro elater stretch yarn;

4. { elater-lap that the relaxes-carded sliver, the cotton fiber-lap-carded sliver }-head also-two also-rove-RING SPINNING-the elater stretch yarn relaxes.
