Polyester chemicals for sale

HT FINE CHEMICALS produce textile chemicals especially for polyester, here to introduce two types of chemicals: 

 


                             
Polyester auxiliaries Fixing Agent for Polyester DG-1

To prevent the dyeing fabric deformation, most synthetic fiber before dyeing should prior to finalize the design (temperature 193 ℃ ~ 200 ℃). But because of the oxygen in air under the light catalysis, with fabric of disperse dyes in polyester fiber and additives occur yellowing,discoloration; Or cause disperse dye in under the action of heat sublimation color shallow, we called sublimation fastness decline collectively referred to as thermal migration fastness decline. This phenomenon is the nearly twenty years textile widely used contains large number of non-ionic surfactant amino silicone oil micro emulsion type softener caused. The solution is to switch to a Special heat sublimation fastness ascending agent (Polyester fixing agent), used to finalize the design can prevent finalize the design before the disperse dye sublimation prison descend.
【Main composition】 Polycation compound
【General properties】
Appearance: light yellow liquid
pH: 5-7.5
Ionicity: Cation
Solubility: easily soluble in water
Stability: stable to acid and alkali
【Product features】
1.Note: this product is high concentrated state choose open diluted multiples of: 2-3 times.
2.Outstanding features: used to disperse dye which can improve the sublimation fastness effectively;
3.Can improve the fastness to washing, less effect of Fabric color.
【Application】
1. Padding process: this article 2 ~ 3% (O.W.F), drying, finalize the design.
2. Impregnation process: 10 ~ 40 g/L.

Polyester Brewing Agent


Helps dyestuffs migrate from high concentration to low concentration or liquor at high temperature and pressure, which is suitable for brewing, leveling and stripping of polyester with disperse dyestuffs.
【Main composition】 Compound of special polyether surfactants and solvents.
【General properties of brewing agent】
Appearance: pale transparent liquid
Ionicity: anionic/nonionic
Solubility: easily soluble in water
【Product features】
1.Strong migration to disperse dyestuffs without shade change after brewing dyeing flaws.
2.Excellent dispersibility, leveling and wetting.
3.Suitable for brewing and stripping of polyester.
【Application】
1. Shades repairing
HT-G:    0.5-1.5 g/L
Bath ratio: 1: 10-20
Temperature & time: 125-130℃ × 20-40 min
2. Stripping
HT-G:     1-3 g/L
Sodium hydrosulfite: 3-5 g/L
NaOH: 3-8 g/L
Bath ratio: 1: 10 -20
Temperature & time: 125-130℃ × 20-40 min
3. Leveling
Disperse dyestuff:    X%
HT-G:     0.5-1.0 g/L
pH:    5
Bath ratio: 1: 20
Temperature & time: 125-130℃ × 20 -40 min
Specific process should be adjusted by testing.

BMA to invest $204 mil to spur ramp up at Queensland coking coal plant

BHP Billiton Mitsubishi Alliance will invest $204 million to speed up the process of ramping up production at its new Caval Ridge coking coal processing plant in Queensland, Australia, to 10 million mt/year, BHP Billiton said Friday.  The investment will go towards a 11 km overland conveyor system, the Caval Ridge Southern Circuit, which is termed as the "missing link" to transport coal from the Peak Downs Mine to the Coal Handling Preparation Plant at the nearby Caval Ridge mine, said BHP Billiton president operations, Minerals Australia, Mike Henry.  "This investment furthers our productivity agenda, reduces costs, releases latent equipment capacity, and strengthens our coal business' global competitiveness," the company said.  It will result in the Caval Ridge preparation plant increasing its throughput to reach its 10 million mt/year capacity, it added.  Construction of the project is scheduled to begin mid-2017 and take 18 months to complete.  In addition t...

The General Steps for Examining the Quality of The Appearance of Textile

The contents for examining To examine the quality of the appearance of textile starts from the accuracy of colors The inspection process is as follows: to test the accuracy of color; raw materials, weaving defects, defect inspection and defect treatment before dyeing defect and finishing defects, in accordance with the standard requirements to determine whether to cut off or drop size. When the color accuracy test is in dispute, the dispute can be settled down according to the measurement results of the electronic color matching system. 1) Material defects The raw materials have obvious defects like big belly yarn evenness is not uniform, there are too many joints, yarn, fiber, silk, specific bad Spandex Covered Yarn Quality, blended yarn uneven mixing and so on, which are likely to cause the fabric etc.. 2) Weaving defects Weaving defects come from many aspects, such as equipment itself, raw materials, environment, temperature and humidity, operator technical level, fabric structu...
