Description
Technical field
The utility model belongs to textile material technical field, and in particular to a kind of compound core-spun yarn.
Background technique
With the improvement of living standards, people have abandoned the idea that is only used for hushing up a scandal, keep warm in terms of dress, start to strong
Health, environmental protection, fashion, comfortable, functionalization direction are developed.Traditional linen-cotton silk hair and petroleum base synthesis chemical fibre have been unable to meet
The exploitation of demand of the modern garment to raw material, environmentally protective fiber natural function fabric has become research hotspot.Polylactic acid
Fiber is starch to extract in the plants such as corn grain in storage for years, cassava, stalk as raw material, and the fermented lactic acid that is converted to is aggregated again,
Biology base chemical synthetic fiber made of spinning.In recent years, in textile and garment enterprise, acid fiber by polylactic starts by people's
Pay attention to.Acid fiber by polylactic produces overall process environmental sound, pollution-free.Meanwhile the fiber has good biodegradability,
If burying and composting after discarded, can be degraded to carbon dioxide and water, go back to nature, free from environmental pollution.And resource is renewable,
Also there is good biocompatibility and Bioabsorbable simultaneously, be a kind of natural function weaving green wood of full ecological, environmental protective
Material.
In recent years, elastic fabric clothing because its it is outstanding it is elastic, with oneself attached body, effect of cultivating one's moral character is good due to be commercially available
Increasingly extensive application.Especially elastic undergarment and sports wear, fabric are close to skin, and the superiority and inferiority of material to human health and is relaxed
Adaptive is most important.Especially in summer, human body is easy to perspire, if elastic undergarment and sports wear increase after being soaked by sweat
Feeling of oppression and heat, bacterium easy to breed.Sports wear also pursues lightweight, to reduce the resistance of motion.Therefore, the excellent of elastic fibers is had both
The natural bacteriostatic pro-skin functional fabric of good elasticity, fabric stability and acid fiber by polylactic is urgently developed.Further, since polylactic acid
Tissue curing can occur at high temperature for fiber non-refractory, and fibre structure is destroyed, or even the problems such as fracture, and fabric is rear
Thermal finalization is had to pass through just in continuous technical process and can guarantee the stability of fabric, therefore when woven fabric includes simultaneously polylactic acid
When fiber and elastic fibers, need to guarantee that product can complete thermal finalization and destroy the characteristic of acid fiber by polylactic.
Utility model content
The purpose of the utility model is to provide a kind of compound core-spun yarns, are suitable for light-weighted movement flexible fabric, tool
There are excellent elasticity, thermal finalization stability and antibacterial skin-friendly.
The utility model provides the following technical solution:
Compound core-spun yarn, including wrap yarn and heart yarn, wrap yarn are polylactic acid long filament, and heart yarn is double groups of skin-core structure
Part fiber filament, the cortex of heart yarn are polylactic acid long filament, and the sandwich layer of heart yarn is polyolefin elastic long filament, and the cross section of heart yarn is more
Side polymorphic structure is equipped with gap between heart yarn and wrap yarn.Gap between heart yarn and wrap yarn has this covering yarn warming
Function, and reduce the averag density of composite yarn, make yarn fabric more lightweight;Polylactic acid as wrap yarn is long
Silk has excellent pro-skin bacteriostasis property, and glossiness is good;The setting temperature of polyolefin elastic long filament and polylactic acid long filament has
115-125 DEG C of intersection, therefore can be flexibly formed in this temperature range by the fabric that the utility model spins;Polyolefin elastic is long
Elasticity is good for silk, is combined into covering yarn with the polylactic acid long filament of cortex and wrap yarn, can be used for movement flexible underwear.
Preferably, cotton layer is additionally provided between wrap yarn and heart yarn, cotton layer enhances the moisture absorption of covering yarn.
Preferably, the cross section of heart yarn is quadrangle hub-and-spoke configuration, and the sky of four spinning tapers is formed between heart yarn and cotton layer
Gap.The star-like heart yarn in quadrangle can make to form biggish gap between heart yarn and cotton layer, while it is biggish transversal to have heart yarn
Area guarantees the tensile strength of heart yarn.
Preferably, the fineness of heart yarn is 10-30D, and the fineness of wrap yarn is 30-50D;The weight ratio of heart yarn and wrap yarn is
1:1.
Preferably, the weight ratio of the cortex of heart yarn and sandwich layer is 1:1.
The beneficial effects of the utility model are: the gap between heart yarn and wrap yarn, makes this covering yarn have warming function
Can, make yarn fabric more lightweight;The outer layer of composite yarn is set to as the polylactic acid long filament of wrap yarn, with skin contact
Soft comfortable and there is excellent pro-skin bacteriostasis property, glossiness is good;The sizing of polyolefin elastic long filament and polylactic acid long filament
Temperature has 115-125 DEG C of intersection, therefore can be flexibly formed in this temperature range by the fabric that the utility model spins;Polyolefin
Elasticity is good for elastic filament, thus the covering yarn integrally elasticity with higher that is combined.
Detailed description of the invention
