Description
Technical field
The present invention relates to field of textiles, more particularly to a kind of elasticity performance difference authentication method.
Background technology
In textile industry, elastic force composite yarn is stronger due to its elasticity, and it is certain special to have during dyeing, weaving cotton cloth
Property, when such as being dyed using cheese form, elastic force composite yarn is after preceding processing, dyeing contour warm and humid processing procedure, bobbin
The elasticity of yarn ectonexine can produce larger difference.To avoid the uneven caused fabric quality problem of elasticity, it is necessary to choose except elasticity
The part yarn excessive with overall difference, and very big waste can be caused by choosing to remove.In addition, stretch yarn natural resiliency is essentially from spandex
Core, and the spandex core of different batches production, its elasticity may have different, when weaving cotton cloth (weft yarn uses elastic force composite yarn), if
Elastic force composite yarn elasticity is variant, then the problems such as causing the uneven door of the cloth cover after weaving cotton cloth, barre, or even in ready-made clothes
Afterwards, there is cloth cover bubble problem in wash water.
It there is no test, the assessment method of elasticity in the industry at present, therefore, to avoid cloth cover problem, production stretch fabric
Enterprise's majority can strictly control the raw yarn batch weaved cotton cloth consistent, including the refuse yarn chosen after dyeing and the residue used of being unstained
A small amount of yarn, all can not be mixed with the yarn of other batches, can directly scrap processing, causes more losses and wastes.
The content of the invention
Based on this, it is necessary to which a variety of elastic force composite yarn elastic performance difference tests can be conveniently used for subtract by providing one kind
The elasticity performance difference authentication method of few wasting of resources.
