Texturing Equipment manufacturers Adapt to Changing Market.

Bulked continuous filament B(BCF) yarns feature a mechanical crimp. BCF yarn can be manufactured via gear crimping, air texturing, and twisting. During the last ten years, many carpet manufacturers have introduced backward integration to increase control over inventory, pricing, availability of product, and specialty niche products. The a..

Optimizing the Fiber-to-Yarn Production Process with a Combined Neural Network/Genetic Algorithm Approach

Yarn quality is an important aspect of fiber to yarn processing. The resulting yarn must possess optimal properties and minimal defects. The fiber to yarn process is very complex, and a mathematical function has not been developed to represent the entire process. Researchers used a neural network combined with a genetic algorithm to simul..

The Prediction of Spinning Performance and Yarn Quality.

Research on the prediction of wool spinning performance and yarn quality developed a quality control package that predicts these variables in terms of the best commercial practice. With this package, a textile mill can quickly evaluate the performance of a yarn lot based on count and twist. The package also uses top properties, including ..

A New Benchmark in Blending

Rieter Spinning System's UNiblend A 80 with four dosing modules ensures uniformly proportioned homogenous blends. The UNiblend A 80 processes a variety of fibers and fiber blends, including cotton, manmade, and waste fibers. Individual dosing modules can

Characteristics of effluent from wet processing of yarns

Wet-processing effluents from the treatment of carpet yarns are examined. it is found that the effluents are only mildly toxic, and then only when mothproofing is carried out from the second bowl or when excessive dye bleeding occurs. This effluent is essentially non-biodegradable. Measures for establishing discharge limits for effluents,..

Fine dtex fibres for nonwovens

Courtaulds has been developing finer decitex fibres for use in nonwovens. Such fibres are used in dry-laid nonwovens for a lower base weight, increased fabric strength, better wicking performance, improved cover, and better barrier and filter performance, improved cover, and better barrier and filter performance. Suitable finishes for use..

Yarn quality, sizing, and weavability

Warp yarn quality and sizing are the two major factors influencing the weavability of warp yarn. Earlier studies at ATIRA have shown that count strength product (CSP) is a good integrated index of yarn quality and correlates well with the warp breakage rate in weaving. This paper presents experimental results of five cotton yarns of 40s c..

Sizing methods for reducing yarn hairiness

The levels of yarn hairiness after conventional sizing, sizing with separate end drying and sizing with reduced end density using two sow-boxes are compared. The effect of the addition of polyvinyl alcohol on hairiness is also evaluated.

Intermingling/interlacing: a broad review

The current state of intermingling/tanglelacing is reviewed and methods used to evaluate yarn quality are evaluated. The mechanism of nip insertion is discussed. There are 33 references.

Study of blend inhomogeneity in air-jet textured yarns

Nylon/nylon, nylon/polyester and polyester/polyester air-jet textured yarns are investigated for blend inhomogeneity after texturing under dry and pre-wetted conditions using cylindrical and convergent/divergent nozzles. Randaom blend irregularity can be achieved unde optimum texturing conditions. use of filaments having dissimilar charac..
